:
1 Let not your heart be troubled: ye believe in God, believe also in me. 2 In my Father's house are many mansions: if it were not so, I would have told you. I go to prepare a place for you. 3 And if I go and prepare a place for you, I will come again, and receive you unto myself; that where I am, there ye may be also. 4 And whither I go ye know, and the way ye know. 5 Thomas saith unto him, Lord, we know not whither thou goest; and how can we know the way? 6 Jesus saith unto him, I am the way, the truth, and the life: no man cometh unto the Father, but by me. 7 If ye had known me, ye should have known my Father also: and from henceforth ye know him, and have seen him. 8 Philip saith unto him, Lord, shew us the Father, and it sufficeth us. 9 Jesus saith unto him, Have I been so long time with you, and yet hast thou not known me, Philip? he that hath seen me hath seen the Father; and how sayest thou then, Shew us the Father? 10 Believest thou not that I am in the Father, and the Father in me? the words that I speak unto you I speak not of myself: but the Father that dwelleth in me, he doeth the works. 11 Believe me that I am in the Father, and the Father in me: or else believe me for the very works' sake. 12 Verily, verily, I say unto you, He that believeth on me, the works that I do shall he do also; and greater works than these shall he do; because I go unto my Father. 13 And whatsoever ye shall ask in my name, that will I do, that the Father may be glorified in the Son. 14 If ye shall ask any thing in my name, I will do it. 15 If ye love me, keep my commandments. 16 And I will pray the Father, and he shall give you another Comforter, that he may abide with you for ever; 17 Even the Spirit of truth; whom the world cannot receive, because it seeth him not, neither knoweth him: but ye know him; for he dwelleth with you, and shall be in you. 18 I will not leave you comfortless: I will come to you. 19 Yet a little while, and the world seeth me no more; but ye see me: because I live, ye shall live also. 20 At that day ye shall know that I am in my Father, and ye in me, and I in you. 21 He that hath my commandments, and keepeth them, he it is that loveth me: and he that loveth me shall be loved of my Father, and I will love him, and will manifest myself to him. 22 Judas saith unto him, not Iscariot, Lord, how is it that thou wilt manifest thyself unto us, and not unto the world? 23 Jesus answered and said unto him, If a man love me, he will keep my words: and my Father will love him, and we will come unto him, and make our abode with him. 24 He that loveth me not keepeth not my sayings: and the word which ye hear is not mine, but the Father's which sent me. 25 These things have I spoken unto you, being yet present with you. 26 But the Comforter, which is the Holy Ghost, whom the Father will send in my name, he shall teach you all things, and bring all things to your remembrance, whatsoever I have said unto you. 27 Peace I leave with you, my peace I give unto you: not as the world giveth, give I unto you. Let not your heart be troubled, neither let it be afraid. 28 Ye have heard how I said unto you, I go away, and come again unto you. If ye loved me, ye would rejoice, because I said, I go unto the Father: for my Father is greater than I. 29 And now I have told you before it come to pass, that, when it is come to pass, ye might believe. 30 Hereafter I will not talk much with you: for the prince of this world cometh, and hath nothing in me. 31 But that the world may know that I love the Father; and as the Father gave me commandment, even so I do. Arise, let us go hence.

[AD 367] Hilary of Poitiers on John 14:1
Our Lord speaks in words deliberately chosen, so that whatever he claims for the Father, he signifies in modest language to be appropriate to himself. Take for example the command, “Believe in God, and believe in me.” He is identified with God in honor. How, I ask you, can he be separated from his nature? He says, “Believe in me also,” just as he said “Believe in God.” Do not the words “in me” signify his nature? Separate the two natures, but then you must also separate the two beliefs. If it is life that we should believe in God without Christ, strip Christ of the name and qualities of God. But if perfect life is given to those who believe in God only when they believe in Christ also, let the careful reader ponder the meaning of the saying, “Believe in God, and believe in me also,” for these words, uniting faith in him with faith in God, unite his nature to God’s. He enjoins first of all the duty of belief in God but adds to it the command that we should believe in himself also, which implies that he is God, since those who believe in God must also believe in him. Yet he excludes the suggestion of a unity contrary to religion, for the exhortation “Believe in God, believe in me also” forbids us to think of him as alone in solitude.

This He says, because it was probable that when they heard they would be troubled. For if the leader of their band, one so entirely fervent, was told that before the cock crew he should thrice deny his Master, it was likely that they would expect to have to undergo some great reverse, sufficient to bend even souls of adamant. Since then it was probable that they considering these things would be astounded, see how He comforts them, saying, Let not your heart be troubled. By this first word showing the power of His Godhead, because, what they had in their hearts He knew and brought to light.

You believe in God, believe also in Me. That is, All dangers shall pass you by, for faith in Me and in My Father is more powerful than the things which come upon you, and will permit no evil thing to prevail against you. Then He adds,
[AD 407] John Chrysostom on John 14:1

And it will permit no evil thing to prevail against you.

(Hom. lxxiii. 1) Or thus: Our Lord having said above to Peter, Whither I go, thou canst not follow Me now, but thou shalt follow Me afterwards, that they might not think that this promise was made to Peter only, He says, In My Father's house are many mansions; i. e. You shall be admitted into that place, as well as Peter, for it contains abundance of mansions, which are ever ready to receive you: If it were not so, I would have told you: I go to prepare a place for you.

(Hom. lxxiii. 1) Having said, Thou canst not follow Me now, that they might not think that they were cut off for ever, He adds: And if I go and prepare a place for you, I will come again and receive you unto Myself, that where I am, there ye may be also: a recommendation to them to place the strongest trust in Him.

(Hom. xxiii. 2) He shows them that He is aware of their curiosity to know His meaning, and thus excites them to put questions to Him.

[AD 430] Augustine of Hippo on John 14:1
1. Our special attention, brethren, must be earnestly turned to God, in order that we may be able to obtain some intelligent apprehension of the words of the holy Gospel, which have just been ringing in our ears. For the Lord Jesus says: Let not your heart be troubled. Believe in God, and believe [or, believe also] in me. That they might not as men be afraid of death, and so be troubled, He comforts them by affirming Himself also to be God. Believe, He says, in God, believe also in me. For it follows as a consequence, that if you believe in God, you ought to believe also in me: which were no consequence if Christ were not God. Believe in God, and believe in Him, who, by nature and not by robbery, is equal with God; for He emptied Himself; not, however, by losing the form of God, but by taking the form of a servant. Philippians 2:6-7 You are afraid of death as regards this servant form, let not your heart be troubled, the form of God will raise it again.

2. But why have we this that follows, In my Father's house are many mansions, but that they were also in fear about themselves? And therein they might have heard the words, Let not your heart be troubled. For, was there any of them that could be free from fear, when Peter, the most confident and forward of them all, was told, The cock shall not crow till you have denied me thrice? Considering themselves, therefore, beginning with Peter, as destined to perish, they had cause to be troubled: but when they now hear, In my Father's house are many mansions: if it were not so, I would have told you; for I go to prepare a place for you, they are revived from their trouble, made certain and confident that after all the perils of temptations they shall dwell with Christ in the presence of God. For, albeit one is stronger than another, one wiser than another, one more righteous than another, in the Father's house there are many mansions; none of them shall remain outside that house, where every one, according to his deserts, is to receive a mansion. All alike have that penny, which the householder orders to be given to all that have wrought in the vineyard, making no distinction therein between those who have labored less and those who have labored more: Matthew 20:9 by which penny, of course, is signified eternal life, whereto no one any longer lives to a different length than others, since in eternity life has no diversity in its measure. But the many mansions point to the different grades of merit in that one eternal life. For there is one glory of the sun, another glory of the moon, and another glory of the stars: for one star differs from another star in glory; and so also the resurrection of the dead. The saints, like the stars in the sky, obtain in the kingdom different mansions of diverse degrees of brightness; but on account of that one penny no one is cut off from the kingdom; and God will be all in all in such a way, that, as God is love, 1 John 4:8 love will bring it about that what is possessed by each will be common to all. For in this way every one really possesses it, when he loves to see in another what he has not himself. There will not, therefore, be any envying amid this diversity of brightness, since in all of them will be reigning the unity of love.

3. Every Christian heart, therefore, must utterly reject the idea of those who imagine that there are many mansions spoken of, because there will be some place outside the kingdom of heaven, which shall be the abode of those blessed innocents who have departed this life without baptism, because without it they cannot enter the kingdom of heaven. Faith like this is not faith, inasmuch as it is not the true and catholic faith. Are you not so foolish and blinded with carnal imaginations as to be worthy of reprobation, if you should thus separate the mansion, I say not of Peter and Paul, or any of the apostles, but even of any baptized infant from the kingdom of heaven; do you not think yourselves deserving of reprobation in thus putting a separation between these and the house of God the Father? For the Lord's words are not, In the whole world, or, In all creation, or, In everlasting life and blessedness, there are many mansions; but He says, In my Father's house are many mansions. Is not that the house where we have a building of God, a house not made with hands, eternal in the heavens? 2 Corinthians 5:1 Is not that the house whereof we sing to the Lord, Blessed are they that dwell in Your house; they shall praise You for ever and ever? Will you then venture to separate from the kingdom of heaven the house, not of every baptized brother, but of God the Father Himself, to whom all we who are brethren say, Our Father, who art in heaven, Matthew 6:9 or divide it in such a way as to make some of its mansions inside, and some outside, the kingdom of heaven? Far, far be it from those who desire to dwell in the kingdom of heaven, to be willing to dwell in such folly with you: far be it, I say, that since every house of sons that are reigning can be nowhere else but in the kingdom, any part of the royal house itself should be outside the kingdom.

4. And if I go, He says, and prepare a place for you, I will come again, and receive you unto myself; that where I am, there ye may be also. And whither I go ye know, and the way ye know. O Lord Jesus, how can You go to prepare a place, if there are already many mansions in Your Father's house, where Your people shall dwell with Yourself? Or if Thou receive them unto Yourself, how will You come again, who never withdrawest Your presence? Such subjects as these, beloved, were we to attempt to explain them with such brevity as seems within the proper bounds of our discourse today, would certainly suffer in clearness from compression, and the very brevity would become itself a second obscurity; we shall therefore defer this debt, which the bounty of our Family-head will enable us to repay at a more suitable opportunity.
[AD 430] Augustine of Hippo on John 14:1
Our Lord consoles his disciples who, as men, would be naturally alarmed and troubled at the idea of his death, by assuring them of his divinity, … “Let not your heart be troubled: you believe in God, believe also in me,” as if they must believe in him if they believed in God. This would not follow unless Christ were God.… You are in fear for this form of a servant. Let not your heart be troubled. The form of God shall raise it up.

Source: TRACTATES ON THE GOSPEL OF JOHN 67.2
[AD 430] Augustine of Hippo on John 14:1-4
(Tr. lxvii. 1) Our Lord consoles His disciples, who, as men, would be naturally alarmed and troubled at the idea of His death, by assuring them of His divinity: Let not your heart be troubled: ye believe in God, believe also in Me; as if they must believe in Him, if they believed in God; which would not follow, unless Christ were God. Ye are in fear for this form of a servant; let not your heart be troubled; the form of God shall raise it up.

(Tr. lxvii. 2) And as the disciples were afraid for themselves, when Peter, the boldest and most zealous of them, had been told, The cock shall not crow, till thou hast denied Me thrice, He adds, In My Father's house are many mansions, by way of an assurance to them in their trouble, that they might with confidence and certainty look forward, after all their trials, to dwelling together with Christ in the presence of God. For though one man is bolder, wiser, juster, holier than another, yet no one shall be removed from that house of God, but each receive a mansion suited to his deserts. The penny indeed which the householder paid to the labourers who worked in his vineyard, was the same to all; for life eternal, which this penny signifies, is of the same duration to all. But there may be many mansions, many degrees of dignity, in that life, corresponding to people's deserts.

(Tr. lxvii. 2) And thus God will be all in all; that is, since God is love, love will bring it to pass, that what each has, will be common to all. That which one loves in another is one's own, though one have it not one's self. And then there will be no envy at superior grace, for in all hearts will reign the unity of love.

(Tr. lxvii. 3) But they are rejected by the Christians, who infer from there being many mansions that there is a place outside the kingdom of heaven, where innocent souls, that have departed this life without baptism, and could not there enter into the kingdom of heaven, remain happy. But God forbid, that when every house of every heir of the kingdom is in the kingdom, there should be a part of the regal house itself not in the kingdom. Our Lord does not say, In eternal bliss are many mansions, but they are in My Father's house.

He means evidently that there are already many mansions, and that there is no need of His preparing one.

(Tract. lxviii. 1) But why does He go and prepare a place, if there are many mansions already? Because these are not as yet so prepared as they will be. The same mansions that He hath prepared by predestination, He prepares by operation. They are prepared already in respect of predestination; if they were not, He would have said, I will go and prepare, i. e. predestinate, a place for you; but inasmuch as they are not yet prepared in respect of operation, He says, And if I go and prepare a place for you. And now He is preparing mansions, by preparing occupants for them. Indeed, when He says, In My Father's house are many mansions, what think we the house of God to be but the temple of God, of which the Apostle saith, The temple of God is holy, which temple ye are. (1 Cor. 3:17) This house of God then is now being built, now being prepared. (c. 3.). But why has He gone away to prepare it, if it is ourselves that He prepares: if He leaves us, how can He prepare us? The meaning is, that, in order that those mansions may be prepared, the just must live by faith: and if thou seest, there is no faith. Let Him go away then, that He be not seen; let Him be hid, that He be believed. Then a place is prepared, if thou live by faith: let faith desire, that desire may enjoy. If thou rightly understandest Him, He never leaves either the place He came from, or that He goes from. He goes, when He withdraws from sight, He comes, when He appears. But except He remain in power, that we may grow in goodness, no place of happiness will be prepared for us.

[AD 444] Cyril of Alexandria on John 14:1
Ye believe in God, believe also in Me.

He is making an able soldier out of one who but now was a coward, and while the disciples were smarting with the anxieties of fear He bids them take to themselves the terrible power of faith. For thus are we safe, and not otherwise, according surely to the song of the Psalmist: The Lord is my illumination and my saviour; whom shall I fear? The Lord is the shield of my life; of tvhom shall I be afraid? For if the all-powerful God fights for us and shields us, who could ever have power to harm us? And who will by any chance advance to such a height of power as to keep the elect in subjection to him, and to force them to submit to the evil designs of his perverse imagination? Or who could take by his spear and lead captive those that wear the panoply of God? Faith therefore is a weapon whose blade is stout and broad, that drives away all cowardice that may spring from expectation of coming suffering, and that renders the darts of evil-doers utterly void of effect and utterly profitless of success in their temptations. And this being the nature of faith, we must further notice another point: Christ bade them believe not in God alone, but also on Himself, not implying thereby that He is at all different from the One Who is in His nature God, I mean as regards identity of essence; but that to believe in God and to suppose that the province of faith must be wholly bound up in this one phrase, is rather a peculiar characteristic of the Jewish imagination, whereas the inclusion of the name of the Son within the compass of faith in God indicates the acceptance of an injunction of evangelic preaching. For those at least who are rightly minded must believe in God the Father, and not merely in the Son, but also in the fact of His Incarnation, and in the Holy Ghost. For the Persons of the Holy and Consubstantial Trinity are distinguished both by difference of names and by the peculiar qualities and special offices of each: for the Father is Father and not Son, the Son again is Son and not Father, and the Holy Ghost is the Spirit peculiar to the Godhead. And yet the Trinity is summed up into a common Unity of Essence, so that our Creed gives us not three Gods, but one God. Still, I maintain that we must preserve accurately the definitions of our faith, not content with saying "We believe in God," but fully explaining our confession, and attaching to each Person the same measure of glory. For in our minds there should be no difference as to the intensity of our faith: our faith in the Father is not to be greater than our faith in the Son, or even than our faith in the Holy Ghost. But one and the same is the extent and the manner of our confession, uttered in regard to each of the three Persons with the same measure of faith; in such a way that herein again the Holy Trinity may appear in Unity of nature, so that the glory that encircles It may be seen in unchallenged perfection, and our souls may display our faith in the Father and in the Son, even in His Incarnation, and in the Holy Ghost. And I believe no man, if he were wise, would make any distinction between the Word of God and the Temple formed from the virgin, at least as regards the question of sonship; for there is One Lord, Jesus Christ, according to the saying of Paul. But let him who would sever into two sons Him Who is One and One alone, know surely that he is denying the faith. The inspired Paul, for instance, in working out very excellently and accurately the doctrine on this point, would have us confess our belief not simply in Christ as the Only-begotten, but also in Him as made like unto us, that is, made man, and as having both died and risen again from the dead. For what does he say? The word is nigh thee, in thy mouth, and in thy heart: that is, the word of faith, which we preach: that if thou shalt say with thy mouth, Jesus is Lord, and shalt believe in thy heart that God raised Him from the dead, thou shalt be saved: for with the heart man believeth unto righteousness; and with the mouth confession is made unto salvation. Now if we believe on the Son as having risen again, who was He that died so that He might rise again? But it is evident that He is reckoned to have died according to the flesh. For His own body was imprisoned in the bonds of death, and restored to life again: for it was a body that shared in our natural life, though containing in itself in full perfection that peculiar indwelling power so mysteriously united to it, namely an energy capable of bestowing life. Whensoever therefore any one shall sever these two natures, and in separating the flesh from Him Who corporeally dwelt therein shall dare to speak of two sons, let him know that he is believing on the flesh alone. For the Divine Scriptures teach us to believe on Him Who was crucified and died and rose again from the dead, as being no other than the Word of God Himself; not so much in regard to identity of essence, for the body of Christ is body and not Word, though it be the body of the Word; but rather in respect of veritable sonship. And if any one were to think that herein we are not speaking with all possible accuracy, he would have to come forward and show us the Word Who is from God dead as regards His Divine nature, a thing which it is impossible or rather impious even to conceive.
[AD 444] Cyril of Alexandria on John 14:1
Let not your heart be troubled.

By saying that Peter's courage will fail him so utterly that he will deny his Master thrice, and will suffer so sad a downfall in one single night, He almost seems by the overwhelming weight of His words to arouse in the disciples the extremity of terror at the dangers before them. Whence it may very well have happened that the other disciples began at once to reason with one another, saying: "What can be the nature, the extent, or the exceeding heaviness of that dread of coming troubles, and of that temptation so irresistible as to attack the chief among us and overcome him, not once only, but many times by the same assault, and that within so brief a space of time? Surely, who among us will escape a yet worse plight, or how can any other among us withstand such an attack, when Peter wavers and yields as of necessity to the grievous weight of the trials that beset him? Vainly it seems have we endured toils for the sake of our duty in following Him: our efforts are ending only in the exhaustion of our vital powers, though they seemed to hold out to us a prospect of life with God." There is surely nothing improbable in supposing that the disciples were thus reasoning in their inmost thoughts: and since it was needful to restore again their drooping spirits, He introduces as it were the necessary antidote to the reasonings and fears that His words had aroused, and bids them arm themselves with a calm and untroubled spirit, saying to them: Let not your heart be troubled. Notice, however, in how guarded a manner He promises them the forgiveness of |232 their coming feebleness of spirit. He does not say plainly: "I will forgive you even in spite of your weakness," or. "I will be present with you none the less, although you deny Me and forsake Me;" His object therein being, not to completely remove their fears of shame, or completely take away their suspicions of failure, lest He should seem to make out their error to be a light matter and teach them to regard as of no account the blame they would incur in their denial of Him. But in bidding them not be troubled, He placed them as it were on the borderland betwixt hope and fear: so that, if they fell into weakness and suffering in their human frailty, the hope of His clemency might help them to recovery; while the fear of stumbling might urge them to fall but seldom, since they had not yet been endowed with the power never to fail at all, not having as yet been clothed with the power from above, from on high, I mean the grace that comes through the Spirit. He bids them therefore not to be troubled, teaching them at once that it was fitting that those who were prepared for the conflict, and ready to enter on the struggles for the sake of the glory that is on high, should be altogether superior to feelings of cowardice: for an untroubled mind is a great help towards a courageous temper: at the same time, with somewhat obscure and not very distinct intimations, yet certainly, sowing the seed of a germinant hope of forgiveness, if ever it should really happen to them in their human weakness to fall away into cowardice. For a mind that is not yet stablished by the grace that comes from above is timid and easily upset, and very apt to be disturbed. For this reason also surely the very wise Paul prays for certain to whom he is writing, in the words: And the peace of Christ, which passeth all understanding, shall guard your hearts. For this is in reality to be untroubled in heart.
[AD 444] Cyril of Alexandria on John 14:1
In commanding them not to be troubled, Jesus placed them, as it were, on the threshold between hope and fear. This way, if they fell into weakness and suffering in their human frailty, the hope of his mercy might help them to recover. On the other hand, the fear of stumbling might urge them to fall less often inasmuch as they had not yet been endowed with the power from above, from on high—I mean the grace that comes through the Spirit that always keeps them from failure.

He acted thus from apprehension of me, and imagining that he could in this manner obliterate the charge against him among the churches, as if he did not entertain strange opinions. He was then an impostor and knave, and in process of time hurried away many with him. And having even venom imbedded in his heart, and forming no correct opinion on any subject, and yet withal being ashamed to speak the truth, this Callistus, not only on account of his publicly saying in the way of reproach to us, "Ye are Ditheists," but also on account of his being frequently accused by Sabellius, as one that had transgressed his first faith, devised some such heresy as the following. Callistus alleges that the Logos Himself is Son, and that Himself is Father; and that though denominated by a different title, yet that in reality He is one indivisible spirit. And he maintains that the Father is not one person and the Son another, but that they are one and the same; and that all things are full of the Divine Spirit, both those above and those below. And he affirms that the Spirit, which became incarnate in the virgin, is not different from the Father, but one and the same. And he adds, that this is what has been declared by the Saviour: "Believest thou not that I am in the Father, and the Father in me? " For that which is seen, which is man, he considers to be the Son; whereas the Spirit, which was contained in the Son, to be the Father. "For," says (Callistus), "I will not profess belief in two Gods, Father and Son, but in one. For the Father, who subsisted in the Son Himself, after He had taken unto Himself our flesh, raised it to the nature of Deity, by bringing it into union with Himself, and made it one; so that Father and Son must be styled one God, and that this Person being one, cannot be two." And in this way Callistus contends that the Father suffered along with the Son; for he does not wish to assert that the Father suffered, and is one Person, being careful to avoid blasphemy against the Father. (How careful he is!) senseless and knavish fellow, who improvises blasphemies in every direction, only that he may not seem to speak in violation of the truth, and is not abashed at being at one time betrayed into the tenet of Sabellius, whereas at another into the doctrine of Theodotus.

[AD 390] Gregory of Nazianzus on John 14:2
Are there many mansions in God’s house, as you have heard, or only one? Of course you will admit that there are many, and not just one. Now, are they all to be filled, or only some, and others not, so that some will be left empty and will have been prepared to no purpose? Of course all will be filled, for nothing can be in vain that has been done by God.

[AD 407] John Chrysostom on John 14:2
As He comforts Peter when bewildered by saying, but you shall follow afterwards, so also He gives this glimpse of hope to the others. For lest they should think that the promise was given to him alone, He says, In My Father's house are many mansions.

If it were not so I would have said to you, I go to prepare a place for you.

That is, The same place which receives Peter shall receive you. For a great abundance of dwellings is there, and it may not be said that they need preparation. When He said, You cannot follow Me now, that they might not deem that they were finally cut off, He added,
[AD 428] Theodore of Mopsuestia on John 14:2
With my Father there is such an abundance that he can give everyone the delights of eternal happiness.… He tells us that here since the custom among us, when space is scarce, is to reserve a place to stay in advance due to lack of available rooms.

[AD 430] Augustine of Hippo on John 14:2
But he is in a certain sense preparing the dwellings by preparing for them the dwellers. As, for instance, when he said, “In my Father’s house are many dwellings.” What else can we suppose the house of God to mean but the temple of God? And what that is, ask the apostle, and he will reply, “For the temple of God is holy, which temple you are.” This is also the kingdom of God that the Son is yet to deliver up to the Father.… For it is to this kingdom, standing then at the right hand, that it shall be said in the end, “Come, you blessed of my Father, receive the kingdom.” In other words, you who were the kingdom but without the power to rule, come and reign so that what you formerly were only in hope, you may now have the power to be in reality. This house of God, therefore, this temple of God, this kingdom of God and kingdom of heaven, is as yet in the process of building, of construction, of preparation, of assembling. There will be dwellings in it even as the Lord is now preparing them. There are in fact such dwellings already even as the Lord has already ordained them.

[AD 444] Cyril of Alexandria on John 14:2
Having forcibly enjoined upon them that they ought not to be troubled, and having bidden them rather believe both in God the Father and in Himself, He now tells them plainly as an encouragement to them to shake off their feebleness of mind, that they shall not be excluded from the holy courts, but shall be made to dwell in the mansions above, living their eternal life in the Church of the Firstborn, in the enjoyment of bliss unending. He says moreover that in His Father's house are many mansions, teaching them thereby that heaven is wide enough for all, and that the world He has created needs no enlargement at all to make it capable of containing those who love Him. And it seems likely that in speaking of the many mansions He wishes also to indicate the different grades of honour, implying that each one who desires to live a life of virtue will receive as it were his own peculiar place, and the glory that is suitable to his own individual acts. Therefore if the mansions in God the Father's home had not been many in number, He would have said that He was going on before them, namely to prepare beforehand the habitations of the saints: but knowing that there are many such, already fully prepared and awaiting the arrival of those who love God, He says that He will depart not for this purpose, but for the sake of securing the way to the mansions above, to prepare a passage of safety for you, and to smooth the path that was impassable in old time. For heaven was then utterly inaccessible to mortal man, and no flesh as yet had ever trodden that pure and all-holy realm of the angels; but Christ was the first Who consecrated for us the means of access to Himself, and granted to flesh a way of entrance into heaven; presenting Himself as an offering to God the Father, as it were the firstfruits of them that are asleep and are lying in the tomb, and the first of mankind that ever appeared in heaven. Therefore also it was that the angels in heaven, knowing nothing of the august and stupendous mystery of the Incarnation, were astonished in wonder at His coming, and exclaim almost in perplexity at the strange and unusual event: Who is this that cometh from Edom? that is, from the earth. But the Spirit did not leave the host above uninstructed in the marvellous wisdom of God the Father, but bade them rather open the heavenly gates in honour to the King and Master of all, proclaiming: Lift up the gates, O ye princes, and be ye lift up, ye everlasting doors, and the King of Glory shall come in. Therefore our Lord Jesus the Christ consecrated for us a new and living way, as Paul says; not having entered into a holy place made with hands, but into heaven itself, now to appear before the face of God for us. For it is not that He may present Himself before the presence of God the Father that Christ has ascended up on high: for He ever was and is and will be continually in the Father, in the sight of Him Who begat Him, for He it is in Whom the Father ever takes delight: but now He Who of old was the Word with no part or lot in human nature, has ascended in human form that He may appear in heaven in a strange and unwonted manner. And this He has done on our account and for our sakes, in order that He, though found as a man, may still in His absolute power as Son, while yet in human form, obey the command: Sit Thou on My right hand, and so may transfer the glory of adoption through Himself to all the race. For in that He has appeared in human form He is still one of us as He sits at the right hand of God the Father, even though He is far above all creation; and He is also Consubstantial with His Father, in that He has come forth from Him as truly God of God and Light of Light. He has presented Himself therefore as Man to the Father on our behalf, that so He may restore us, who had been removed from the Father's presence by the ancient transgression, again as it were to behold the Father's face. He sits there in His position as Son, that so also we through Him may be called sons and children of God. For this reason also Paul, who insists that he has Christ speaking by his voice, teaches us to regard the events that happened in the life of Christ alone as common to the whole race; saying that God raised us up with Him, and made us to sit with Him in the heavenly places, in Christ. For to Christ, as by nature Son, it belongs as a special prerogative to sit at the Father's side, and the glory of this dignity we can ascribe rightly and truly to Him, and Him alone. But the fact that Christ Who sits there is in all points like unto us, in that He has appeared as Man, while we believe Him to be God of God, seems to confer on us also the privilege of this dignity. For even if we shall not sit at the side of the Father Himself,----for how could the servant ever ascend to equal honour with the master?----yet nevertheless Christ promised the holy disciples that they should sit on thrones. For He says: When the Son of Man shall sit on the throne of His glory, ye also shall sit upon twelve thrones, judging the twelve tribes of Israel.

"I shall not then," He says, "depart to prepare mansions for you, for many there are already, and to make new habitations for creation is needless; but I go to make ready a place for you on account of the sin that has mastery over you, that so those who are on the earth may be able to be mingled with the holy angels; for else the saintly multitude of those above would never have mingled with those who had been so denied. But now, when I shall have accomplished this work, and united the world below to the world above, and given you a path of access to the city on high, I will return again at the time of the regeneration, and receive you 5 with Myself; that where I am, there ye may be also." And this is also in the mind of Paul, when he thus writes in his own letter: For this we say unto you by the word of the Lord, that we that are alive, that are left unto the coming of the Lord, shall in no wise precede them that are fallen asleep. For the Lord Himself shall descend from heaven, with a shout, with the voice of the archangel, and with the trump of God: and the dead in Christ shall rise first: then we that are alive, that are left, shall together with them be caught up in the clouds, to meet the Lord in the air: and so shall we ever be with the Lord.
[AD 407] John Chrysostom on John 14:3
So earnest have I been concerning this matter, that I should already have been given up to it, had not preparation been made long ago for you. Showing them that they ought to be very bold and confident. Then that He may not seem to speak as though enticing them, but that they may believe the thing to be so, He adds,
[AD 430] Augustine of Hippo on John 14:3
1. We acknowledge, beloved brethren, that we are owing you, and ought now to repay, what was left over for consideration, how we can understand that there is no real mutual contrariety between these two statements, namely, that after saying, In my Father's house are many mansions: if it were not so, I would have told you, that I go to prepare a place for you;— where He makes it clear enough that He said so to them for the very reason that there are many mansions there already, and there is no need of preparing any; — the Lord again says: And if I go and prepare a place for you, I will come again and receive you unto myself; that where I am, there ye may be also. How is it that He goes and prepares a place, if there are many mansions already? If there were not such, He would have said, I go to prepare. Or if the place has still to be prepared, would He not then also properly have said, I go to prepare? Are these mansions in existence already, and yet needing still to be prepared? For if they were not in existence, He would have said, I go to prepare. And yet, because their present state of existence is such as still to stand in need of preparation, He does not go to prepare them in the same sense as they already exist; but if He go and prepare them as they shall be hereafter, He will come again and receive His own to Himself: that where He is, there they may be also. How then are there mansions in the Father's house, and these not different ones but the same, which already exist in a sense in which they can admit of no preparation, and yet do not exist, inasmuch as they are still to be prepared? How are we to think of this, but in the same way as the prophet, who also declares of God, that He has [already] made that which is yet to be. For he says not, Who will make what is yet to be, but, Who has made what is yet to be. Therefore He has both made such things and is yet to make them. For they have not been made at all if He has not made them; nor will they ever be if He make them not Himself. He has made them therefore in the way of fore-ordaining them; He has yet to make them in the way of actual elaboration. Just as the Gospel plainly intimates when He chose His disciples, that is to say, at the time of His calling them; Luke 6:13 and yet the apostle says, He chose us before the foundation of the world, Ephesians 1:4 to wit, by predestination, not by actual calling. And whom He did predestinate, them He also called; Romans 8:30 He has chosen by predestination before the foundation of the world, He chooses by calling before its close. And so also has He prepared those mansions, and is still preparing them and He who has already made the things which are yet to be, is now preparing, not different ones, but the very mansions He has already prepared: what He has prepared in predestination, He is preparing by actual working. Already, therefore, they are, as respects predestination; if it were not so, He would have said, I will go and prepare, that is, I will predestinate. But because they are not yet in a state of practical preparedness, He says, And if I go and prepare a place for you, I will come again, and receive you unto myself.

2. But He is in a certain sense preparing the dwellings by preparing for them the dwellers. As, for instance, when He said, In my Father's house are many dwellings, what else can we suppose the house of God to mean but the temple of God? And what that is, ask the apostle, and he will reply, For the temple of God is holy, which [temple] you are. 1 Corinthians 3:17 This is also the kingdom of God, which the Son is yet to deliver up to the Father; and hence the same apostle says, Christ, the beginning, and then they that are Christ's in His presence; then [comes] the end, when He shall have delivered up the kingdom to God, even the Father; 1 Corinthians 15:23-24 that is, those whom He has redeemed by His blood, He shall then have delivered up to stand before His Father's face. This is that kingdom of heaven whereof it is said, The kingdom of heaven is likened unto a man who sowed good seed in his field. But the good seed are the children of the kingdom; and although now they are mingled with tares, at the end the King Himself shall send forth His angels, and they shall gather out of His kingdom all things that offend. Then shall the righteous shine forth as the sun in the kingdom of their Father. The kingdom will shine forth in the kingdom when [those that are] the kingdom shall have reached the kingdom; just as we now pray when we say, Your kingdom come. Matthew 6:10 Even now, therefore, already is the kingdom called, but only as yet being called together. For if it were not now called, it could not be then said, They shall gather out of His kingdom everything that offends. But the realm is not yet reigning. Accordingly it is already so far the kingdom, that when all offenses shall have been gathered out of it, it shall then attain to sovereignty, so as to possess not merely the name of a kingdom, but also the power of government. For it is to this kingdom, standing then at the right hand, that it shall be said in the end, Come, you blessed of my Father, receive the kingdom; Matthew 25:34 that is, you who were the kingdom, but without the power to rule, come and reign; that what you formerly were only in hope, you may now have the power to be in reality. This house of God, therefore, this temple of God, this kingdom of God and kingdom of heaven, is as yet in the process of building, of construction, of preparation, of assembling. In it there will be mansions, even as the Lord is now preparing them; in it there are such already, even as the Lord has already ordained them.

3. But why is it that He went away to make such preparation, when, as it is certainly we ourselves that are the subjects in need of preparation, His doing so will be hindered by leaving us behind? I explain it, Lord, as I can: it was surely this You signified by the preparation of those mansions, that the just ought to live by faith. Romans 1:17 For he who is sojourning at a distance from the Lord has need to be living by faith, because by this we are prepared for beholding His countenance. 2 Corinthians 5:6-8 For blessed are the pure in heart, for they shall see God; Matthew 5:8 and He purifies their hearts by faith. Acts 15:9 The former we find in the Gospel, the latter in the Acts of the Apostles. But the faith by which those who are yet to see God have their hearts purified, while sojourning at a distance here, believes what it does not see; for if there is sight, there is no longer faith. Merit is accumulating now to the believer, and then the reward is paid into the hand of the beholder. Let the Lord then go and prepare us a place; let Him go, that He may not be seen; and let Him remain concealed, that faith may be exercised. For then is the place preparing, if it is by faith we are living. Let the believing in that place be desired, that the place desired may itself be possessed; the longing of love is the preparation of the mansion. Prepare thus, Lord, what You are preparing; for You are preparing us for Yourself, and Yourself for us, inasmuch as You are preparing a place both for Yourself in us, and for us in You. For You have said, Abide in me, and I in you. As far as each one has been a partaker of You, some less, some more, such will be the diversity of rewards in proportion to the diversity of merits; such will be the multitude of mansions to suit the inequalities among their inmates; but all of them, none the less, eternally living, and endlessly blessed. Why is it that You go away? Why is it You come again? If I understand You aright, Thou withdrawest not Yourself either from the place You go from, or from the place You come from: You go away by becoming invisible, You come by again becoming manifest to our eyes. But unless You remain to direct us how we may still be advancing in goodness of life, how will the place be prepared where we shall be able to dwell in the fullness of joy? Let what we have said suffice on the words which have been read from the Gospel as far as I will come again, and receive you to myself. But the meaning of what follows, That where I am, there ye may be also; and whither I go ye know, and the way ye know, we shall be in a better condition— after the question put by the disciple, that follows, and which we also may be putting, as it were, through him— for hearing, and more suitably situated for making the subject of our discourse.
[AD 430] Augustine of Hippo on John 14:3
But why has he gone away to prepare it, if it is ourselves that he prepares? If he leaves us, how can he prepare us? The meaning is that in order that those mansions may be prepared, the just must live by faith … and if you see, there is no faith.… Let Christ go away then so that he is not seen. Let him remain concealed that faith may be exercised. Then a place is prepared if you live by faith. Let faith desire so that the place desired may itself be possessed. The longing of love is the preparation of the mansion. In this way, Lord, prepare what you are preparing. For you are preparing us for yourself and yourself for us, inasmuch as you are preparing a place both for yourself in us and for us in you. For you have said, “Abide in me, and I in you.” As far as each one has been a partaker of you, some less, some more, such will be the diversity of rewards in proportion to the diversity of merits. The multitude of mansions will suit the multitude of inequalities among their occupants. But all of them, nonetheless, will live eternally and will be endlessly blessed.

[AD 430] Augustine of Hippo on John 14:3
When he says, therefore, “That where I am, there you may be also,” where else were they to be but in himself? In this way he is also in himself, and they, therefore, are just where he is, that is, in himself. Accordingly, he himself is that eternal life that is yet to be ours, when he has received us unto himself. As he is that life eternal, so is it in him, that where he is there shall we be also, that is to say, in himself. “For as the Father has life in himself”—and certainly that life that he has is in no way different from what he is himself as its possessor—“so has he given to the Son to have life in himself.” This is so because he is the very life that he has in himself. But will we then actually be what he is, [namely], the life when we begin our existence in that life, that is, in himself? Certainly not, for he, by his very existence as the life, has life. He is himself what he has. And just as the life is in him, so he is in himself. But we are not that life. We are partakers of his life. And we shall be there in such a way as to be wholly incapable of being in ourselves what he is. But even while we ourselves are not the life, we will be able to have him as our life. And he himself has life because of the very fact that he himself is the life.

But since he already knew that there were many homes already fully prepared and awaiting the arrival of those who love God, he says that he will depart, but not for this purpose. Rather, he leaves in order to secure the way to the mansions above, to prepare a passage of safety for you and to smooth the paths that were formerly impassible.

Otherwise, the holy multitude of those above would never mingle with those [below] who were so defiled. But now, when I shall have accomplished the work of uniting the world below with that above—giving you a way of access to the city on high as well—I will return again at the time of regeneration and ‘receive you with myself, so that where I am, there you may be also.’ ”

[AD 407] John Chrysostom on John 14:4
Do you see that He gives them proof that these things were not said without a meaning? And He used these words, because He knew in Himself that their souls now desired to learn this. For Peter said what he said, not in order to learn, but that he might follow. But when Peter had been rebuked, and Christ had declared that to be possible which for the time seemed impossible, and when the apparent impossibility led him to desire to know the matter exactly, therefore He says to the others, And the way ye know. For as when He has said, You shall deny Me, before any one spoke a word, searching into their hearts, He said, Be not troubled, so here also by saying You know, He disclosed the desire which was in their heart, and Himself gives them an excuse for questioning. Now the, Where are You going? Peter used from a very loving affection, Thomas from cowardice.
[AD 430] Augustine of Hippo on John 14:4
1. We have now the opportunity, dearly, beloved, as far as we can, of understanding the earlier words of the Lord from the later, and His previous statements by those that follow, in what you have heard was His answer to the question of the Apostle Thomas. For when the Lord was speaking above of the mansions, of which He both said that they already were in His Father's house, and that He was going to prepare them; where we understood that those mansions already existed in predestination, and are also being prepared through the purifying by faith of the hearts of those who are hereafter to inhabit them, seeing that they themselves are the very house of God; and what else is it to dwell in God's house than to be in the number of His people, since His people are at the same time in God, and God in them? To make this preparation the Lord departed, that by believing in Him, though no longer visible, the mansion, whose outward form is always hid in the future, may now by faith be prepared: for this reason, therefore, He had said, And if I go away and prepare a place for you, I will come again, and receive you to myself; that where I am, there ye may be also. And whither I go ye know, and the way ye know. In reply to this, Thomas says unto Him, Lord, we know not whither You go: and how can we know the way? Both of these the Lord had said that they knew; both of them this other declares that he does not know, to wit, the place to which, and the way whereby, He is going. But he does not know that he is speaking falsely; they knew, therefore, and did not know that they knew. He will convince them that they already know what they imagine themselves still to be ignorant of. Jesus says unto him, I am the way, and the truth, and the life. What, brethren, does He mean? See, we have just heard the disciple asking, and the Master instructing, and we do not yet, even after His voice has sounded in our ears, apprehend the thought that lies hid in His words. But what is it we cannot apprehend? Could His apostles, with whom He was talking, have said to Him, We do not know You? Accordingly, if they knew Him, and He Himself is the way, they knew the way; if they knew Him who is Himself the truth, they knew the truth; if they knew Him who is also the life, they knew the life. Thus, you see, they were convinced that they knew what they knew not that they knew.

2. What is it, then, that we also have not apprehended in this discourse? What else, think you, brethren, but just that He said, And whither I go ye know, and the way ye know? And here we have discovered that they knew the way, because they knew Him who is the way: the way is that by which we go; but is the way the place also to which we go? And yet each of these He said that they knew, both whither He was going, and the way. There was need, therefore, for His saying, I am the way, in order to show those who knew Him that they knew the way, which they thought themselves ignorant of; but what need was there for His saying, I am the way, and the truth, and the life, when, after knowing the way by which He went, they had still to learn whither He was going, but just because it was to the truth and to the life He was going? By Himself, therefore, He was going to Himself. And whither go we, but to Him, and by what way go we, but by Him? He, therefore, went to Himself by Himself, and we by Him to Him; yea, likewise both He and we go thus to the Father. For He says also in another place of Himself, I go to the Father; and here on our account He says, No man comes unto the Father but by me. And in this way, He goes by Himself both to Himself and to the Father, and we by Him both to Him and to the Father. Who can apprehend such things save he who has spiritual discernment? And how much is it that even he can apprehend, although thus spiritually discerning? Brethren, how can you desire me to explain such things to you? Only reflect how lofty they are. You see what I am, I see what you are; in all of us the body, which is corrupted, burdens the soul, and the earthly tabernacle weighs down the mind that muses upon many things. Wisdom 9:15 Do we think we can say, To You have I lifted up my soul, O Thou that dwellest in the heavens? But burdened as we are with so great a weight, under which we groan, how shall I lift up my soul unless He lift it with me who laid His own down for me? I shall speak then as I can, and let each of you who is able receive it. As He gives, I speak; as He gives, the receiver receives; and as He gives, there is faith for him who cannot yet receive with understanding. For, says the prophet, If you will not believe, you shall not understand.

3. Tell me, O my Lord, what to say to Your servants, my fellow-servants. The Apostle Thomas had You before him in order to ask You questions, and yet could not understand You unless he had You within him; I ask You because I know that You are over me; and I ask, seeking, as far as I can, to let my soul diffuse itself in that same region over me where I may listen to You, who usest no external sound to convey Your teaching. Tell me, I pray, how it is that You go to Yourself. Did Thou formerly leave Yourself to come to us, especially as You came not of Yourself, but the Father sent You? I know, indeed, that You emptied Yourself; but in taking the form of a servant, Philippians 2:7 it was neither that Thou laid down the form of God as something to return to, or that You lost it as something to be recovered; and yet You came, and placed Yourself not only before the carnal eyes, but even in the very hands of men. And how otherwise save in Your flesh? By means of this You came, yet abiding where You were; by this means You returned, without leaving the place to which You had come. If, then, by such means You came and return, by such means doubtless You are not only the way for us to come unto You, but wast the way also for Yourself to come and to return. For when You returned to the life, which You are Yourself, then of a truth that same flesh of Yours You brought from death unto life. The Word of God, indeed, is one thing, and man another; but the Word was made flesh, or became man. And so the person of the Word is not different from that of the man, seeing that Christ is both in one person; and in this way, just as when His flesh died. Christ died, and when His flesh was buried, Christ was buried (for thus with the heart we believe unto righteousness, and thus with the mouth do we make confession unto salvation Romans 10:10); so when the flesh came from death unto life, Christ came to life. And because Christ is the Word of God, He is also the life. And thus in a wonderful and ineffable manner He, who never laid down or lost Himself, came to Himself. But God, as was said, had come through the flesh to men, the truth to liars; for God is true, and every man a liar. Romans 3:4 When, therefore, He withdrew His flesh from among men, and carried it up there where no liar is found, He also Himself— for the Word was made flesh— returned by Himself, that is, by His flesh, to the truth, which is none other but Himself. And this truth, we cannot doubt, although found among liars, He preserved even in death; for Christ was once dead, but never false.

4. Take an example, very different in character and wholly inadequate, yet in some lit tle measure helpful to the understanding of God, from things that are in peculiarly intimate subjection to God. See here in my own case, while as far as pertains to my mind I am just the same as yourselves, if I keep silence I am so to myself; but if I speak to you something suited to your understanding, in a certain sense I go forth to you without leaving myself, but at the same time approach you and yet quit not the place from which I proceed. But when I cease speaking, I return in a kind of way to myself, and in a kind of way I remain with you, if you retain what you have heard in the discourse I am delivering. And if the mere image that God made is capable of this, what may not God, the very image of God, not made by, but born of God; whose body, wherein He came forth to us and returned from us, has not ceased to be, like the sound of my voice, but abides there, where it shall die no more, and death shall have no more dominion over it? Romans 6:9 Much more, perhaps, might and ought to have been said on these words of the Gospel; but your souls ought not to be burdened with spiritual food, however pleasant, especially as the spirit is willing, but the flesh is weak. Matthew 26:41
[AD 444] Cyril of Alexandria on John 14:4
"I Myself," He seems to say, "am going on before to make ready for you the path of entrance into the heavens: but if you wish, and if it is the delight of your heart, to rest within those mansions, and if you have devoted all your endeavours to reach the city above and to dwell in the company of the holy spirits, then ye know the way, which is Myself; for assuredly through Me. and none other, will you gain that blessing so marvellous. No other will ever open the heavens to you, or ever smooth for you the ground that none on earth could hitherto ever tread or ever know, except Myself alone." And the saying is true. Therefore surely it was that the prophet Jeremiah, speaking by the Spirit, bade us ever seek this way most diligently, saying: Stand ye in the ways, and ask for the everlasting paths of the Lord, and see what is the good way, and walk therein; and ye shall find sanctification to your souls. For the ways and paths of the Lord are, according to the prophet, the saving precepts of the holy prophets; but if any one devote his mind to them, he will find the Good Way, that is, Christ, through Whom cometh the perfect sanctification to our souls: for we are justified by faith, and are made partakers of the Divine nature by sharing in the gift of the Holy Spirit. Nay, more, Isaiah himself, that prophet of mighty-sounding voice, thus heralded forth to us the coming of Christ, saying: There shall be in that time an undefiled way, and it shall be called a holy way; where by the phrase "in that time" he clearly means to speak of the time of the Incarnation of the Only-begotten: for He has made Himself for us an Undefiled and Holy Way, along which whosoever shall travel will at the appointed season behold the fair brightness of the city of the saints, and the Jerusalem which is free. And again, the inspired Psalmist himself says to us, addressing himself as to God the Father: Teach me, O Lord, in Thy way: for he is desirous to be instructed in the laws that are given by Christ, as one who is not unaware that he will travel onward even to the city above, if led by the Evangelic teaching, journeying straight towards every blessing. And it would not be difficult to bring forward also many other testimonies out of the prophets, from which we might know assuredly that Jesus was called by them the holy "Way"; but I consider that there is |240 no necessity for laying excessive stress on arguments whose effective use is so self-evident. "Ye know therefore," He says, "the way by which you yourselves also may pass to the mansions above;" signifying thereby just this, and nothing else: "There are indeed resting-places in God the Father's home, many and glorious; and I am going on before you to prepare for you a means of access whereby you may in all boldness enter the regions yonder. But be well assured that no man would ever be able to reach those courts save through Me, and Me alone." If therefore any one fall away from the love of Christ, or (giving way to profane babblings and to impure and unnatural suggestions on the part of men whose hearts are set on false slanders) venture to degrade to the condition of slavery His nature so ineffable and incomprehensible, numbering among those born in the world Him Who is the Word begotten of the Father's essence in perfect freedom, or having any like base thoughts; let that man be well assured that he has lost the track of the journey to heaven above, and that he has been "deceived as to the waggon-wheels of his own farm," according to the saying of some one, and will most certainly undergo the penalties that are merited by those who cling to the world below. Therefore also the most wise Paul says of those who in madness have refused to order their lives in the manner of Christ, rushing back to the shadows of the law, that they have been alienated from Christ, and have fallen from grace in their desire to be justified by the law. For even as he who strays from the direct and beaten path will certainly be exposed to the disastrous consequences of his wandering, just so methinks and in the same degree will they who have rejected the righteousness that is in Christ, and have set at nought the teaching of the Evangelic dispensation, never see the city above, and never dwell with the saints. For Christ alone is the Way that can bring them thither.
[AD 444] Cyril of Alexandria on John 14:4
“I myself,” he seems to say, “am going ahead to prepare the path of entry into the heavens.” But if you wish, and if it is the delight of your heart to rest within those mansions, and if you have devoted everything to reaching that city above and dwelling in the company of the holy spirits—then “you know the way,” which is myself. For assuredly it is through me and no one else that you will ever gain that marvelous blessing. No other will ever open the heavens to you or smooth over the ground that one on earth could ever walk—except myself alone.

We shall be able to see from what follows: If ye had known Me, ye should have known My Father also. In His incarnation asserting His Divinity, He maintained a certain order of sight and knowledge: separating the time of seeing from that of knowing. For Him, who He saith must be known, He speaks of as already seen: that henceforward they might from this revelation have knowledge of the Divine Nature which they had all along seen in Him.

If the Jews questioned among themselves when they heard (of His departure), although desirous to be rid of Him, much more would those desire to learn, who wished never to be separated from Him. They feared therefore to ask Him, but yet they asked Him, from their great love and anxiety. What then says Christ?
[AD 407] John Chrysostom on John 14:5-7
(Hom. xxiii. 2) He shows them that He is aware of their curiosity to know His meaning, and thus excites them to put questions to Him.

(Hom. lxxiii. 2) If the Jews, who wished to be separated from Christ, asked whither He was going, much more would the disciples, who wished never to be separated from Him, be anxious to know it. So with much love, and, at the same time, fear, they proceed to ask: Thomas saith unto Him, Lord, we know not whither Thou goest; and how can we know the way?

(Hom. lxxiii. 2) For if, He says, ye have Me for your guide to the Father, ye shall certainly come to Him. Nor can ye come by any other way. (c. 6:44) Whereas He had said above, No man can come to Me, except the Father draw him, now He says, No man cometh unto the Father but by Me, thus equalling Himself to the Father. The next words explain, Whither I go ye know, and the way ye know. If ye had known Me, He says, ye should have known My Father also; i. e. If ye had known My substance and dignity, ye would have known the Father's. They did know Him, but not as they ought to do. Nor was it till afterwards, when the Spirit came, that they were fully enlightened. On this account He adds, And from henceforth ye know Him, know Him, that is, spiritually. And have seen Him, i. e. by Me; meaning that he who had seen Him, had seen the Father. They saw Him, however, not in His pure substance, but clothed in flesh.

[AD 430] Augustine of Hippo on John 14:5-7
(Tr. lxix. 1) Our Lord had said that they knew both, Thomas says that they knew neither. Our Lord cannot lie; they knew not that they did know. Our Lord proves that they did: Jesus saith unto Him, I am the way, the truth, and the life.

(de Verb. Dom. s. liv) As if He said, I am the way, whereby thou wouldest go; I am the truth, whereto thou wouldest go; I am the life, in which thou wouldest abide. The truth and the life every one understands (capit); but not every one hath found the way. Even the philosophers of the world have seen that God is the life eternal, the truth which is the end of all knowledge. And the Word of God, which is truth and life with the Father, by taking upon Him human nature, is made the way. Walk by the Man, and thou wilt arrive at God. For it is better to limp on the right way, than to walk ever so stoutly by the wrong.

(Tr. lxix. 2) They knew then the way, because they knew He was the way. But what need to add, the truth, and the life? Because they were yet to be told whither He went. He went to the truth; He went to the life. He went then to Himself, by Himself. But didst Thou leave Thyself, O Lord, to come to us? (c. 3.). I know that Thou tookest upon Thee the form of a servant; by the flesh Thou camest, remaining where Thou wast; by that Thou returnedst, remaining where Thou hadst come to. If by this then Thou camest, and returnedst, by this Thou wast the way, not only to us, to come to Thee, but also to Thyself to come, and to return again. And when Thou wentest to life, which is Thyself, Thou raisedst that same flesh of Thine from death to life. Christ therefore went to life, when His flesh arose from death to life. And since the Word is life, Christ went to Himself; Christ being both, in one person, i. e. Word-flesh. Again, by the flesh God came to men, the truth to liars; for God is true, but every man a liar. When then He withdrew Himself from men, and lifted up His flesh to that place in which no liar is, the same Christ, by the way, by which He being the Word became flesh, by Himself, i. e. by His flesh, by the same returned to Truth, which is Himself, which truth, even amongst the liars He maintained unto death. Behold I myself1, if I make you understand what I say, do in a certain sense go to you, though I do not leave myself. And when I cease speaking, I return to myself, but remain with you, if ye remember what ye have heard. If the image which God hath made can do this, how much more the Image which God hath begotten? Thus He goes by Himself, to Himself and to the Father, and we by Him, to Him and to the Father.

The Comforter is holy, and the Word is holy, the Son of the Father, by whom He made all things, and exercises a providence over them all. This is the Way which leads to the Father, the Rock, the Defence, the Key, the Shepherd, the Sacrifice, the Door of knowledge, through which have entered Abraham, and Isaac, and Jacob, Moses and all the company of the prophets, and these pillars of the world, the apostles, and the spouse of Christ, on whose account He poured out His own blood, as her marriage portion, that He might redeem her. All these things tend towards the unity of the one and only true God. But the Gospel possesses something transcendent [above the former dispensation], viz. the appearing of our Saviour Jesus Christ, His passion, and the resurrection itself. For those things which the prophets announced, saying, "Until He come for whom it is reserved, and He shall be the expectation of the Gentiles," have been fulfilled in the Gospel, [our Lord saying, ] "Go ye and teach all nations, baptizing them in the name of the Father, and of the Son, and of the Holy Ghost." All then are good together, the law, the prophets, the apostles, the whole company [of others] that have believed through them: only if we love one another.

Since, therefore, the tradition from the apostles does thus exist in the Church, and is permanent among us, let us revert to the Scrip-rural proof furnished by those apostles who did also write the Gospel, in which they recorded the doctrine regarding God, pointing out that our Lord Jesus Christ is the truth.

For whereas in the Gospels, and in the epistles of the apostles, the name of Christ is alleged for the remission of sins; it is not in such a way as that the Son alone, without the Father, or against the Father, can be of advantage to anybody; but that it might be shown to the Jews, who boasted as to their having the Father, that the Father would profit them nothing, unless they believed on the Son whom He had sent. For they who know God the Father the Creator, ought also to know Christ the Son, lest they should flatter and applaud themselves about the Father alone, without the acknowledgment of His Son, who also said, "No man cometh to the Father but by me." But He, the same, sets forth, that it is the knowledge of the two which saves, when He says, "And this is life eternal, that they might know Thee, the only true God, and Jesus Christ, whom thou hast sent." Since, therefore, from the preaching and testimony of Christ Himself, the Father who sent must be first known, then afterwards Christ, who was sent, and there cannot be a hope of salvation except by knowing the two together; how, when God the Father is not known, nay, is even blasphemed, can they who among the heretics are said to be baptized in the name of Christ, be judged to have obtained the remission of sins? For the case of the Jews under the apostles was one, but the condition of the Gentiles is another. The former, because they had already gained the most ancient baptism of the law and Moses, were to be baptized also in the name of Jesus Christ, in conformity with what Peter tells them in the Acts of the Apostles, saying, "Repent, and be baptized every one of you in the name of the Lord Jesus Christ, for the remission of sins, and ye shall receive the gift of the Holy Ghost. For this promise is unto you, and to your children, and to all that are afar off, even as many as the Lord our God shall call." Peter makes mention of Jesus Christ, not as though the Father should be omitted, but that the Son also might be joined to the Father.

Nor ought custom, which had crept in among some, to prevent the truth from prevailing and conquering; for custom without truth is the antiquity of error. On which account, let us forsake the error and follow the truth, knowing that in Esdras also the truth conquers, as it is written: "Truth endureth and grows strong to eternity, and lives and prevails for ever and ever. With her there is no accepting of persons or distinctions; but what is just she does: nor in her judgments is there unrighteousness, but the strength, and the kingdom, and the majesty, and the power of all ages. Blessed be the Lord God of truth!" This truth Christ showed to us in His Gospel, and said, "I am the truth."

And since we have Him as an Advocate with the Father for our sins, let us, when as sinners we petition on behalf of our sins, put forward the words of our Advocate.

For the Lord Himself said: ‘I and the Father will come and make our home with him’ [John 14:23]. Next, the Son is life-for He said: ‘I am the life’ (John 14:6)- and so we are said to be given life in the Spirit... But when we are given life in the Spirit, Christ Himself is said to live in us.

Whatever is devoid of death or decay is that which is without end. That, likewise, is called everlasting that does not exist only for a time. That, therefore, which is neither everlasting nor without end is surely seen in the nature that is perishable and mortal. And so, the one who predicates “unendingness” of the one and only God and does not include the Son in the assertion of “unendingness” and “eternity” maintains by such a proposition that he whom he thus contrasts with the eternal and unending is perishable and temporary. But we, even when we are told that God “alone has immortality,” understand by “immortality” the Son. For life is immortality, and the Lord is that life who said, “I am the Life.”

[AD 397] Ambrose of Milan on John 14:6
If they say that the Father alone is true God, they cannot deny that God the Son alone is the truth. For Christ is the truth. Is the truth then something inferior to him that is true, seeing that according to the use of terms a person is called true from the word truth, as also wise from wisdom, just from justice? We do not consider it so between the Father and the Son. For there is nothing lacking in the Father, because the Father is full of truth. And the Son, because he is the truth, is equal to him who is true.

[AD 407] John Chrysostom on John 14:6
Why then, when He was asked by Peter, 'Where are You going,' did He not say directly, 'I go to the Father, but you cannot come now'? Why did He put in a circuit of so many words, placing together questions and answers? With good reason He told not this to the Jews; but why not to these? He had indeed said both to these and to the Jews, that He came forth from God, and was going to God, now He says the same thing more clearly than before. Besides, to the Jews He spoke not so clearly; for had He said, You cannot come to the Father but by Me, they would straightway have deemed the matter mere boasting; but now by concealing this, He threw them into perplexity. But why, says some one, did He speak thus both to the disciples and to Peter? He knew his great forwardness, and that he would by reason of this the more press on and trouble Him; in order therefore to lead him away, He hides the matter. Having then succeeded in what He wished by the obscurity and by veiling His speech, He again discloses the matter. After saying, Where I am, no man can come, He adds, In My Father's house are many mansions; and again, No man comes to the Father but by Me. This He would not tell them at first, in order not to throw them into greater despondency, but, now that He has soothed them, He tells them. For by Peter's rebuke He cast out much of their despondency; and dreading lest they should be addressed in the same way, they were the more restrained. I am the Way. This is the proof of the, No man comes to the Father but by Me; and, the Truth, and the Life, of this, that these things shall surely be. There is then no falsehood with Me, if I am 'the Truth'; if I am 'Life' also, not even death shall be able to hinder you from coming to Me. Besides; if I am 'the Way,' you will need none to lead you by the hand; if I am also 'the Truth,' My words are no falsehoods; if I am also 'Life,' though ye die you shall obtain what I have told you. Now His being the Way, they both understood and allowed, but the rest they knew not. They did not indeed venture to say what they knew not. Still they gained great consolation from His being the Way. If, says He, I have sole authority to bring to the Father, you shall surely come there; for neither is it possible to come by any other way. But by saying before, No man can come to Me except the Father draw him; and again, If I be lifted up from the earth, I shall draw all men unto Me John 12:32; and again, No man comes to the Father but by Me John 14:6; He shows Himself equal to Him who begot Him. But how after saying, Whither I go ye know, and the way ye know, has He added,
[AD 407] John Chrysostom on John 14:6
“I am the way.” This is the proof that “No one comes to the Father but by me.” “The truth and the life” prove that these statements will be carried out. “There is, then, no falsehood with me if I am ‘the truth.’ It is also the same if I am ‘life,’ since not even death shall be able to stop you from coming to me. Besides, if I am ‘the way,’ you will need no one to lead you by the hand. And, if I am also ‘the truth,’ my words are not false. If I am also ‘life,’ although you die you shall obtain what I have told you.” His being “the way” they both understood and allowed, but the rest they did not understand. Indeed they did not venture to say what they did not know. Still they gained great consolation from his being “the way.” “If,” he says, “I have sole authority to bring you to the Father, you shall surely come this way. For neither is it possible to come by any other way.”

Persevere now in walking by faith in the truth, that you may succeed in coming at a definite and due time to the sight of the same truth. For as the apostle says, “While staying here in the body, we are away from the Lord. For we are walking by faith, not by sight.” We are led to the direct sight and vision of the Father by Christian faith. That is why the Lord says, “No one comes to the Father except through me.”

The one who is himself the Truth and the Word, by whom all things were made, was made flesh so that he might dwell among us. And yet, the apostle still says, “Even though we have known Christ after the flesh, yet from now on we know him no more.” For Christ, desiring not only to give the possession to those who had completed the journey but also to be himself the way to those who were just setting out, determined to take a fleshly body. This is the source of that expression, “The Lord created me in the beginning of his way.” Those who desire to come [to the Father] begin their journey in [the Son]. The apostle, therefore, although still on the way … had already passed over the beginning of the way and had now no further need of it. And yet, everyone who wants to attain to the truth and to rest in eternal life has to start the journey by this way. For Jesus says, “I am the way, and the truth and the life”; that is, by me men and women come. To me they come, in me they rest. For when we come to him, we come to the Father also, because through an equal an equal is known.

[AD 444] Cyril of Alexandria on John 14:6
Christ willed not as yet to tell His disciples in so many words that He was going away to the world above and returning to His Father, although in dark hints and through many impressive sayings He had been referring to the event. But one of His disciples, that one being Thomas, now questions Him directly, and by introducing at the same time a sort of argument, all but forces Him in spite of Himself to tell them plainly both whither it is that He is going, and where the path of His journey lies. For we know not, said he, whither Thou goest: so then, how could we know the way? Christ in His reply evades the excessive curiosity of His disciple, for He does not give the desired answer at all, but treasuring up the question in His all-knowing mind, and rather reserving it for a more convenient moment, He in His kindness unfolds a truth which it was essential for them to learn. He says, therefore: I am the Way, I the Truth, I the Life. Now as to the truth of the Lord's saying in these words concerning Himself, no reasonable person can ever have felt the slightest shadow of doubt; yet I conceive it is needful to examine the question attentively. For how comes it that, whereas in the inspired Scriptures He is spoken of as Light, and Wisdom, and Power, and by many other names, He selects a few only as being of very especial significance for the present occasion, calling Himself the Way, and the Truth, and the Life? For the real force of the words is deep and not easily discernible, as it seems to me; yet still we must not shrink from attempting to discover it. I shall say exactly what occurs to my own mind, commending to those who are wont to speculate more keenly the task of thinking out a higher meaning.

There are then three means whereby we shall reach the Divine courts that are above and enter the Church of the firstborn; namely, by practice in virtue of every kind, by faith in rightness of doctrine, and by hope of life to come. Is there any one else than our Lord Jesus the Christ, who could ever be a leader, a helper, or a means for granting us success in such matters as these? Surely not: do not think it. For He Himself has taught us things that are beyond the Law; He has pointed out to us the way that any one might safely take as leading to a virtue mighty in operation, and to a zealous and unhindered performance of those acts that are after the pattern of Christ. And so He Himself is the Truth, He is the Way; that is, the true boundary of faith, and the exact rule and standard of an unerring conception concerning God. For by a true belief in the Son, namely as begotten of the very essence of God the Father, and as bearing the title of Son in its fullest and truest meaning, and not even in any sense a made or created being, we shall then clothe ourselves in the confidence of a true faith. For he who has received the Son as a Son, has fully confessed a belief also in Him of Whose essence the Son is, and knows and will straightway accept God as the Father. Therefore He is the Truth, He is the Life; for none other will restore to us the life which is within our hopes, namely, that life which is in incorruption, and blessedness, and sanctification: for He it is that raises us up, and will bring us back again from the death we died under the ancient curse, to the state in which we were at the beginning. In Him therefore and through Him, all that is best and all that is precious has already appeared, and will appear for us. And notice again that the meaning connected with these words is very suitable to the idea involved in the previous verses. For while the disciple was still in doubt, and saying: How know we the way? He showed him briefly that since they knew Himself to be the motive cause, the leader, and the prince of the blessings that would bring them to the world above, they would have no further need of knowing the way.

But since He has added hereunto the words: No one cometh unto the Father but by Me, let us give some attention to this point in what we are about to say; first examining the question how one could go to the Father. We approach Him in two ways: either by becoming holy, as far as is possible for humanity, we thus are led to cleave to a holy God, for it is written: Ye shall be holy, for I am holy; or else we arrive, through faith and contemplation, at that knowledge of the Father which is as it were in a mirror darkly, as it is written. But no man would ever be holy and make progress in a life according to the rule of virtue, unless Christ were the guide of his footsteps in everything: and none would ever be united to God the Father save through the mediation of Christ. For He is Mediator between God and men, through Himself and in Himself uniting humanity to God. For since He is born of the essence of God the Father, in that He is the Word, the Effulgence, and the very Image, He is one with the Father, being wholly in the Father, and having the Father in Himself; while in that He has become a man like unto us, He is united to all on the earth in everything except in our sin: and so He has become a sort of border-ground, containing in Himself all that concurs to unity and friendship.

No man therefore will come to the Father, that is, will appear as a partaker of the Divine nature, save through Christ alone. For if He had not become a Mediator by taking human form, our condition could never have advanced to such a height of blessedness; but now, if any one approach the Father in a spirit of faith and reverent knowledge, he will do so, by the help of our Saviour Christ Himself. For even as I said just now, so I will say again, the course of the argument being in no wise different. By accepting the Son truly as Son a man will arrive also at the knowledge of God the Father: for one could not be looked upon as a son, except the father who |244 begat him were fully acknowledged at the same time. The knowledge of the Father is thus necessarily concurrent with belief in the Son, and knowledge of the Son with belief in the Father. And so the Lord says most truly: No man cometh unto the Father but by Me. For the Son is in nature and essence an Image of God the Father, and not (as some have thought) a Being moulded merely into His likeness by attributes specially bestowed, Himself being by nature something essentially different, and being so esteemed.
[AD 444] Cyril of Alexandria on John 14:6
There are three means by which we shall reach the divine courts that are above and enter the church of the firstborn: by practicing every kind of virtue; by faith in right doctrine; by hope of the life to come. Is there anyone other than our Lord Jesus the Christ who could ever be a leader, a helper or a means for granting us success in these kinds of things? Surely not! Do not even entertain such an idea! For he himself has taught us things beyond the Law. He has pointed out to us the way that anyone might safely take that would lead to a life of incredible virtue and to a highly motivated and unhindered performance of those actions that follow the pattern of Christ. And so he himself is the truth, he is the way, that is, the true boundary of faith and the exact rule and standard of an unerring conception concerning God. For by a true belief in the Son, namely, as begotten of the very essence of God the Father and as bearing the title of Son in its fullest and truest meaning—and not even in any sense a made or created being—we shall then clothe ourselves in the confidence of a true faith. For one who has received the Son as a Son has fully confessed a belief also in him of whose essence the Son is, and that person knows and will immediately accept God as the Father. Therefore he is the truth, he is the life, for no one else will restore to us the life that is within our hopes, namely, that life that is in incorruption, blessedness and sanctification. For it is he that raises us up and who will bring us back again from the death we died under the ancient curse to the state in which we were at the beginning.

As soon as the soul leaves the body, stench, corruption, rottenness, the worm, ashes, horror and everything that is loathsome to the sight take its place. When God leaves, immediately the stench of faithlessness, the corruption of sin, the rottenness of the vices, the worm of guilt, the ashes of vanities and the horror of infidelity enter the soul, and there comes to pass in the living tomb of the body the death of the soul now buried.

The cross of Christ, which was set up for the salvation of mortals, is both a sacrament and an example: a sacrament whereby the divine power takes effect, an example whereby one’s devotion is excited. For to those who are rescued from the prisoner’s yoke, redemption further procures the power of following the way of the cross by imitation. For if the world’s wisdom so prides itself in its error that everyone follows the opinions and habits and whole manner of life of him whom he has chosen as his leader, how shall we share in the name of Christ except by being inseparably united to him who is, as he himself asserted, “the way, the truth and the life”—the way, that is, of holy living, the truth of divine doctrine and the life of eternal happiness.

How can knowledge of him be knowledge of the Father? For the apostles see him wearing the aspect of that human nature that belongs to him. But God is not encumbered with body and flesh and is unrecognizable by those who dwell in our weak and fleshly body. The answer is given by the Lord, who asserts that under the flesh that, in a mystery, he had taken, his Father’s nature dwells within him.… He makes a distinction between the time of seeing and the time of knowing. He says that from this time onward they shall know him whom they had already seen and so shall possess, from the time of this revelation onward, the knowledge of that nature on which, in him, they had gazed for so long.

And a recognition of God the Son produces a recognition of God the Father.

And from this time onward you shall know him, and you have seen him.” The [knowing] belongs to the future; the [seeing] belongs to the present. Both are brought about “by me.” By “sight,” he means knowledge by intellectual perception. For those who are seen we may see but not know. Those, however, who are known we cannot both know and not know.… These words are used so that you may learn that the one who has seen him knows him who begat him. But they beheld him not in his unveiled essence but clothed with flesh.

[AD 430] Augustine of Hippo on John 14:7
1. The words of the holy Gospel, brethren, are rightly understood only if they are found to be in harmony with those that precede; for the premises ought to agree with the conclusion, when it is the Truth that speaks. The Lord had said before, And if I go and prepare a place for you, I will come again and receive you unto myself; that where I am, there ye may be also: and then had added, And whither I go ye know, and the way ye know; and showed that all He said was that they knew Himself. What, therefore, the meaning was of His going to Himself by Himself—for He also lets the disciples see that it is by Him that they are to come to Him—we have already told you, as we could, in our last discourse. When He says, therefore, That where I am, there ye may be also, where else were they to be but in Himself? In this way is He also in Himself, and they, therefore, are just where He is, that is, in Himself. Accordingly, He Himself is that eternal life which is yet to be ours, when He has received us unto Himself; and as He is that life eternal, so is it in Him, that where He is there shall we be also, that is to say, in Himself. For as the Father has life in Himself, and certainly that life which He has is in no wise different from what He is Himself as its possessor, so has He given to the Son to have life in Himself, inasmuch as He is the very life which He has in Himself. But shall we then actually be what He is, (namely), the life, when we shall have begun our existence in that life, that is, in Himself? Certainly not, for He, by His very existence as the life, has life, and is Himself what He has; and as the life, is in Him, so is He in Himself: but we are not that life, but partakers of His life, and shall be there in such wise as to be wholly incapable of being in ourselves what He is, but so as, while ourselves not the life, to have Him as our life, who has Himself the life on this very account that He Himself is the life. In short, He both exists unchangeably in Himself and inseparably in the Father. But we, when wishing to exist in ourselves, were thrown into inward trouble regarding ourselves, as is expressed in the words, My soul is cast down within me: and changing from bad to worse, cannot even remain as we were. But when by Him we come unto the Father, according to His own words, No man comes unto the Father but by me, and abide in Him, no one shall be able to separate us either from the Father or from Him.

2. Connecting, therefore, His previous words with those that follow, He proceeded to say, If you had known me, you should certainly have known my Father also. This conforms to His previous words, No man comes unto the Father but by me. And then He adds: And from henceforth ye know Him, and have seen Him. But Philip, one of the apostles, not understanding what he had just heard, said, Lord, show us the Father, and it suffices us. And the Lord replied to him, Have I been so long time with you, and yet have ye not known me, Philip? He that sees me, sees also the Father. Here you see He complains that He had been so long time with them, and yet He was not known. But had He not Himself said, And whither I go ye know, and the way ye know; and on their saying that they knew it not, had convinced them that they did know, by adding the words: I am the way, and the truth, and the life? How, then, says He now, Have I been so long time with you, and have ye not known me? when, in fact, they knew both whither He went and the way, on no other grounds save that they really knew Himself? But this difficulty is easily solved by saying that some of them knew Him, and others did not, and that Philip was one of those who did not know Him; so that, when He said, And whither I go ye know, and the way ye know, He is understood as having spoken to those that knew, and not to Philip, who has it said to him, Have I been so long time with you, and have ye not known me, Philip? To such, then, as already knew the Son, was it now also said of the Father, And from henceforth ye know Him, and have seen Him: for such words were used because of the all-sided likeness subsisting between the Father and the Son; so that, because they knew the Son, they might henceforth be said to know the Father. Already, therefore, they knew the Son, if not all of them, those at least to whom it is said, And whither I go ye know, and the way ye know; for He is Himself the way. But they knew not the Father, and so have also to hear, If you have known me, you have known my Father also; that is, through me you have known Him also. For I am one, and He another. But that they might not think Him unlike, He adds, And from henceforth ye know Him, and have seen Him. For they saw His perfectly resembling Son, but needed to have the truth impressed on them, that exactly such as was the Son whom they saw,was the Father also whom they did not see. And to this points what is afterwards said to Philip, He that sees me, sees also the Father. Not that He Himself was Father and Son, which is a notion of the Sabellians, who are also called Patripassians, condemned by the Catholic faith; but that Father and Son are so alike, that he who knows one knows both. For we are accustomed to speak in this way of two who closely resemble each other, to those who are in the habit of seeing one of them, and wish to know what like the other is, so that we say, In seeing the one, you have seen the other. In this way, then, is it said He that sees me, sees also the Father. Not, certainly, that He who is the Son is also the Father, but that the Son in no respect disagrees with the likeness of the Father. For had not the Father and Son been two persons, it would not have been said, If you have known me, you have known my Father also. Such is certainly the case for no one, He says, comes unto the Father but by me: if you have known me, you have known my Father also; because it is I, who am the only way to the Father, that will lead you to Him, that He also may Himself become known to you. But as I am in all respects His perfect image, from henceforth ye know Him in knowing me; and have seen Him, if you have seen me with the spiritual eyesight of the soul.

3. Why, then, Philip, do you say, Show us the Father, and it suffices us? Have I been so long time with you, and yet have ye not known me, Philip? He that sees me, sees the Father also. If it interests you much to see this, believe at least what you see not. For how, He says, do you say, Show us the Father? If you have seen me, who am His perfect likeness, you have seen Him to whom I am like. And if you can not directly see this, do you not believe, at least, that I am in the Father, and the Father in me? But Philip might say here, I see You indeed, and believe Your full likeness to the Father; but is one to be reproved and rebuked because, when he sees one who bears a likeness to another, he wishes to see that other to whom he is like? I know, indeed, the image, but as yet I know only the one without the other; it is not enough for me, unless I know that other whose likeness he bears. Show us, therefore, the Father, and it suffices us. But the Master really reproved the disciple because He saw into the heart of his questioner. For it was with the idea, as if the Father were somehow better than the Son, that Philip had the desire to know the Father: and so he did not even know the Son, because believing that He was inferior to another. It was to correct such a notion that it was said, He that sees me, sees the Father also. How do you say, Show us the Father? I see the meaning of your words: it is not the original likeness you seek to see, but it is that other you think the superior. Do you not believe that I am in the Father, and the Father in me? Why do you desire to dis cover some distance between those who are thus alike? Why do you crave the separate knowledge of those who cannot be separated? What, after this, He says not only to Philip, but to all of them together, must not now be thrust into a corner, in order that, by His help, it may be the more carefully expounded.
[AD 444] Cyril of Alexandria on John 14:7
And from henceforth ye know Him, and have seen Him.

Wonderful, it seems to me, is the gracious intention and the unspeakably profound purpose that underlies this saying also. For after having just said: If ye had known Me, ye would have known My Father also, and seeming thus to reproach His disciples for their ignorance of truths so essential, He immediately passes on to comfort them with the assurance: From henceforth ye know Him and have seen Him. For since they were destined to become rulers of the Churches throughout the world, in obedience to the Saviour's commission: Go ye and make disciples of all nations, for this reason above all others, as I think, He first utters a most useful truth of universal reference to all time, that whosoever knoweth the Son will most assuredly also know God the Father of Whom the Son is begotten; and then in His kindness He goes on to testify that His disciples possess this knowledge: not speaking at all by way of compliment, for He could never utter aught but truth, but inasmuch as they really knew Him and had most fully acknowledged Him. For that they knew and had believed that the Lord was really Son of God can by no means be a matter of doubt to right-minded persons. For how came it that Nathaniel the Israelite, when he heard Christ say: Before that Philip called thee, when thou wast under the fig-tree, I saw thee, immediately put forth his full confession of faith, saying: Rabbi, Thou art the Son of God, Thou art the King of Israel? Moreover, when the sea was marvellously and supernaturally calmed, how was it that those who were in the ship worshipped Him, saying: Truly Thou art the Son of God? Will any one maintain that this saying was uttered by men who did not know that He was God and begotten of God the Father? Surely such an one would give a most convincing proof of his want of intelligence. When, in the district of Caesarea Philippi, they were asked by Christ Himself: Who do men say that I the Son of Man am? did not they first of all give the opinions of others? Some, they say, think Thou art Elijah, and others Jeremiah, or one of the prophets. But Who they themselves said that He was, they shrank not from telling Him plainly, all speaking by the mouth of their chief, and that was Peter, affirming positively: Thou art the Christ, the Son of the Living God. Yet when Christ says: If ye had known Me, ye would have known My Father also, do not suppose that the saying is uttered entirely for the sake of the disciples: it is rather a general declaration laid down for all, the holy disciples being taken as representatives of all mankind.

Notice carefully then how clearly we shall find that they have not been ignorant that He is God and the Son of God; but when He spoke of Himself as "the Way" of God, then they did not understand what seemed to be spoken enigmatically: and this will comprise the full extent of any charge of ignorance that can be brought against them. For this reason surely, having briefly refuted the idea of their inability to understand what was told them indirectly, and then grounded on this a declaration affecting all men, teaching plainly that whosoever knows not the Son will also lose his knowledge of the Father; He then most justly testifies to the disciples' knowledge of Him, inasmuch as they had already made open confession of their faith: and this He does in the words: From henceforth ye know Him and have seen Him. And He uses the word "henceforth," not with reference to that hour or that day on which He was uttering His teaching on these matters: but He uses the word in order to contrast with the days of the old and first dispensation the new and recently-arisen season of His own presence, whereby the knowledge of the Father as seen through the Son has been made clearer for all men throughout the world. Therefore also in the Book of Psalms, as speaking to God the Father, He says: The knowledge of Thee has been greatly magnified by Me. For having seen the Son excelling in deeds incredibly marvellous, and with God-befitting authority easily accomplishing His own good pleasure, we have been led on thereby to accept in reverent admiration the knowledge of the Father, believing it to be no other than the knowledge of the Son Who came forth from Him. From henceforth, therefore, ye know Him and have seen Him. For through the Son we have been led, as I said just now, to know Who the Father is, and not only have we known, but we have also beheld or seen. For knowledge indicates that mental contemplation at which one may very well arrive concerning the Divine and ineffable nature that is above all, and through all, and in all. But to have seen the Truth signifies the fulfilment of our knowledge by the vision of the miraculous works. For we have not simply known the bare fact that the Father is in His nature Life; nor have we had within ourselves the knowledge of the matter ideally and theoretically only: we have seen the truth carried out by the Son, in giving life to the dead, and restoring to existence those who had seen corruption. We have not simply known the fact that the God and Father of all is in His nature Life, and has the whole creation in subjection beneath His feet; and that He rules in sovereign authority over all things made by Him, so that, as it is written: All His works shake and tremble at Him, we have seen evidence of the truth in the action of the Son, when, in rebuking the sea and the winds, He said with all authority, Peace, be still.

Since therefore He was intending to say that "you have not only known, but have even seen the Father," He considered it essential to prefix the word "henceforth;" and why so? The reason was this: the law of Moses declared to the children of Israel, The Lord thy God is one Lord, and never offered the doctrine concerning the Son to the men of old time; it was content with driving them away from the worship of many gods and calling them to adore One, and One only: but our Lord Jesus the Christ by His Incarnation made known to us the Father through Himself by many signs and mighty works, and has shown that the nature of the Godhead which we believe to be contained in the Holy Trinity is in truth One. And so He does well to say "henceforth," on account of the imperfection of knowledge possessed by those who walk after the law, and order their lives in that system. And we must note well that in saying that He Himself and not the Father has been seen, He in no way denies the real and individual existence of the God and Father from Whom He is; nor does He even say that He Himself is the Father, inasmuch as He claims to have come to represent the Father's Person. But since He is Consubstantial with the Father, He says that His Father is seen in His Person; just as if an ordinary man's son, wishing to indicate plainly the nature of his father, were to point to himself and say to any chance inquirer in the matter: "In me thou hast seen my father." Here again, however, the Godhead will entirely transcend the power of the example to illustrate.
[AD 444] Cyril of Alexandria on John 14:7
If ye had known Me, ye would have known My Father also.

Some may perchance say and think that the Son is here speaking of His own accord, and at His own suggestion. But it is not so. For He never uttered anything in an uncalled-for, or merely casual way; though He does occasionally repeat Himself in a most instructive manner, especially because of the utter inability of some to follow His teaching. But in the present instance His words are most profitable to us in connection with what He had said just before. For when Thomas questioned Him, asking: "Whither wilt Thou depart; or how can we know the way, if we know not whither Thou wilt go?" He thereupon answered him most effectively in the words: I am the Way, and the Life, and the Truth; and again: No man cometh unto the Father but by Me; thereby showing that if any one willed to know the way which would lead to eternal life, he would strive with all diligence to know Christ. But since it was likely that some, who had been trained in Jewish rather than in Evangelic doctrine, might suppose that a confession of faith in and a knowledge of One Person only out of all was sufficient for a right belief, and that it was needless to learn the doctrine concerning the Holy and Consubstantial Trinity; Christ seems to absolutely exclude those who hold this opinion from a true knowledge concerning God, unless they would also accept Himself. For it is through the Son that we must draw near to God the Father. For in a manner analogous to our acceptance of the Offspring, we shall arrive at our belief in the Parent also. For it is utterly impossible to doubt that a belief in the sonship of Son, as begotten of the essence of the Father, will certainly lead to a knowledge of the Father.

According then to the simpler and more obvious interpretation, He must be supposed to have spoken with this meaning: but if any one believes that He is employing subtle ideas so as to penetrate to the very root of the whole matter, he will find once more that the Son is teaching truth. The Divine Nature, indeed, is utterly incomprehensible by any human intellect; and to claim for oneself to have fully discovered Who and What in very essence the Creator of the universe is, would involve a display of absolute folly. Still, it is not impossible for us, though in a shadowy and uncertain manner, to obtain some kind of knowledge by holding up as a mirror to our mind's eye the catalogue of Divine attributes which are inherent by nature in the Son. For from a knowledge of what Christ is in Himself, and of the works He has wrought when He became Incarnate as well as before His Incarnation, one might afterwards ascend by analogous reasoning to a contemplation of the Father Who begat Him. Behold, I pray thee, the glory and the power that were His: gaze on His authority, that extended without hindrance over all. Tell me, is there anything conceivable or inconceivable that He does not appear to have achieved with perfect success at His own free will, both before and since His Incarnation? Nay, more, He Who showed Himself to us so mighty by the evidence of His works, says expressly: I and the Father are One, and: He that hath seen Me hath seen the Father. We must therefore, in reliance on what we have just quoted, pass onward from the Likeness to the Archetype, and from the Very Image to the full realisation of Him Whom the Very Image represents. We do not say, as some of the heterodox would have us say, that the Son is fashioned after the Father's likeness by means of certain attributes bestowed upon Him from without; nor even would we admit, as some in error suppose, that He is styled the Image of God the Father as possessing His glory, His power, and His wisdom, although being Himself really of a different nature: these are the foolish babblings of the heretics, sheer nonsense delicately veiled, or rather absolute impiety, designed according to their unholy and ungodly object to overthrow and destroy the doctrine of the Son's Consubstantiality with the Father. But Christ is a Son in very truth, begotten ineffably and incomprehensibly of the essence of God the Father, and as such is the Very Image and Likeness and Effulgence of Him, bearing innate within Himself the proper characteristics of His Father's essence, and possessing in all their beauty the attributes that are naturally the Father's. For we will not imitate the heretics in their extravagant madness, and degrade our own minds to such a depth of foolishness as to say that Christ in any respect differs from a Being Who is in very nature God, or to deny that He is begotten of the essence of God the Father, and so refuse to attribute to Him the glory of God; neither would we allow that any nature which was created and brought into existence out of nothing could ever, without undergoing change, be endowed with the Divine power and wisdom, or ever be such as the Divine and ineffable nature of God the Father may be imagined to be. For else, what distinction could any longer exist between the Creator and the creature; or what could intervene or sever, that is to say, between the thing made and Him Who made it, in regard to identity and essence? For if a creature possesses glory and power and wisdom exactly to the same degree as God the Father, I should be utterly unable to say, and I conceive the heretics would be in the same perplexity, wherein God's superiority can possibly consist, or how He can be greater than we or than His creature. Therefore we maintain that the Son is in no wise fashioned so as to resemble the Father by the addition of attributes from without, nor is He like a representation in a picture, adorned by us with merely ideal colours which gloss over and falsely indicate the royal dignity; but He is truly the Very Image and Likeness of His Father, displaying to us the Father's nature in clearest light by the graces that are His own by nature. And this is why Christ pronounces it impossible for any to have fully known the Father without first knowing Himself, that is, the Son.
[AD 328] Alexander of Alexandria on John 14:8
Whence, also, to Philip, who then was desirous to see Him, the Lord shows this abundantly. For when he said, "Show us the Father"
[AD 367] Hilary of Poitiers on John 14:8
A declaration so new startled Philip. Our Lord is seen to be man. He confesses Himself to be the Son of God, declares that, if He were known, the Father would be known, that, if He is seen, the Father is seen. The familiarity of the Apostle therefore breaks forth into questioning our Lord, Philip said to Him, Lord, show us the Father, and it suffices us. He did not deny He could be seen, but wished to be shown him; nor did he wish to see with his bodily eyes, but that He whom he had seen might be made manifest to his understanding. Hehad seen the Son in the form of man, but how through that form He saw the Father, he did not know. This he wants to be strewn him, strewn to his understanding, not set before his eyes; and then he will be satisfied: And it suffices us.
He reproves the ignorance of Philip in this respect. For whereas his actions had been strictly divine, such as walking on the water, commanding the winds, remitting sins, raising the dead, He complained that in His assumed humanity, the Divine nature was not discerned. Accordingly to Philip’s request, to be strewn the Father, Our Lord answers, He that has seen Me, has seen the Father.
He does not mean the sight of the bodily eye: for His fleshly part, born of the Virgin, does not avail towards contemplating the form and image of God in Him; but the Son of God being known with the understanding, it follows that the Father is known also, forasmuch as He is the image of God, not differing from but expressing His Author. For our Lord’s expressions do not spear; of one person solitary and without relationship, but teach us His birth. The Father also excludes the supposition of a single solitary person, and leaves us no other doctrine but that the Father is seen in the Son, by the incommunicable likeness of birth.
For what excuse was there for ignorance of the Father, or what necessity to show Him, when the Father was seen in the Son by His essential nature, while by the identity of unity, the Begotten and the Begetter are one: Believe you not that I am in the Father and the Father in Me? .
Butthe Father is in the Son, and the Son in the Father, not by a conjunction of two harmonizing essences, nor by a nature grafted into a more capacious substance as in material bodies, in which it is impossible that what is within can be made external to that which contains it; but by the birth of a nature which is life from life; forasmuch as from God nothing but God canbe born.
The unchangeable God follows, so to speak, His own nature, by begetting unchangeable God. Nor does the perfect birth of unchangeable God from unchangeable Godforsake His own nature. We understand then here the nature of God subsisting in Him, since God is in God, nor besides Him who is God, can any other be God.
Wherein He neither desires Himself to be the Son, nor hides the existence of His Father’s power in Him. In that He speaks, it is Himself that speaks in His own person; in that He speaks not of Himself, He witnesses His nativity, that He is God from God.
That the Father dwells in the Son, show that He is not single, or solitary; that the Father works by the Son, shows that He is not different or alien. As He is not solitary who does not speak from Himself, so neither is He alien and separable who speaks by Him. Having shown then that the Father spoke and worked in Him, He formally states this union: Believe Me that I am in the Father, and the Father in Me: that they might not think that the Father works and speaks in the Son as by a mere agent or instrument, not by the unity of nature implied in His Divine birth.
[AD 367] Hilary of Poitiers on John 14:8
The novel sound of these words of Jesus disturbed the apostle Philip. A man is before their eyes. This man asserts that he is the Son of God and declares that when they have known him they will know the Father. He tells them that they have seen the Father and that, because they have seen him, they shall know him hereafter.… And so Philip spoke out with the loyalty and confidence of an apostle, requesting, “Lord, show us the Father, and that will suffice.” He was not tampering with the faith. It was only a mistake made in ignorance.… Philip did not deny that the Father could be seen but only asked that he might see him. He did not ask that the Father should be unveiled so that he could see him with his bodily eyes, but that he might have some further indication that would enlighten him concerning how the Father could be seen. For he had seen the Son under the aspect of humanity but cannot understand how he could thereby have seen the Father.

(vii. de Trin) Or thus: When it is said that the Son is the way to the Father, is it meant that He is so by His teaching, or by His nature? We shall be able to see from what follows: If ye had known Me, ye should have known My Father also. In His incarnation asserting His Divinity, He maintained a certain order of sight and knowledge: separating the time of seeing from that of knowing. For Him, who He saith must be known, He speaks of as already seen: that henceforward they might from this revelation have knowledge of the Divine Nature which they had all along seen in Him.

(vii. de Trin) A declaration so new startled Philip. Our Lord is seen to be man.

[AD 407] John Chrysostom on John 14:8
1. The Prophet said to the Jews, You had the countenance of a harlot, thou were shameless towards all men. Jeremiah 3:3, Septuagint Now it seems fitting to use this expression not only against that city, but against all who shamelessly set their faces against the truth. For when Philip said to Christ, Show us the Father, He replied, Have I been so long time with you, and have you not known Me, Philip? And yet there are some Who even after these words separate the Father from the Son. What proximity do you require closer than this? Indeed from this very saying some have fallen into the malady of Sabellius. But let us, leaving both these and those as involved in directly opposite error, consider the exact meaning of the words. Have I been so long time with you, and have you not known Me, Philip? He says. What then? Replies Philip, Are you the Father after whom I enquire? No, He says. On this account He said not, have you not known Him, but, have you not known Me, declaring nothing else but this, that the Son is no other than what the Father is, yet continuing to be a Son. But how came Philip to ask this question? Christ had said, If you had known Me, you should have known My Father also John 14:7, and He had often said the same to the Jews. Since then Peter and the Jews had often asked Him, Who is the Father? since Thomas had asked Him, and no one had learned anything clear, but His words were still not understood; Philip, in order that He might not seem to be importunate and to trouble Him by asking in his turn after the Jews, Show us the Father, added, and it suffices us, we seek no more. Yet Christ had said, If you had known Me, you should have known My Father also, and by Himself He declared the Father. But Philip reversed the order, and said, Show us the Father, as though knowing Christ exactly. But Christ endures him not, but puts him in the right way, persuading him to gain the knowledge of the Father through Himself, while Philip desired to see Him with these bodily eyes, having perhaps heard concerning the Prophets, that they saw God. But those cases, Philip, were acts of condescension. Wherefore Christ said, No man has seen God at any time John 1:18; and again, Every man that has heard and has learned from God comes unto Me. John 6:45 You have neither heard His voice at any time, nor seen His shape. John 5:37 And in the Old Testament, No man shall see My face, and live. Exodus 33:20 What says Christ? Very reprovingly He says, Have I been so long time with you, and have you not known Me, Philip? He said not, have you not seen, but, have you not known Me. Why, Philip might say, do I wish to learn concerning You? At present I seek to see Your Father, and You say unto me, have you not known Me? What connection then has this with the question? Surely a very close one; for if He is that which the Father is, yet continuing a Son, with reason He shows in Himself Him who begot Him. Then to distinguish the Persons He says, He that has seen Me has seen the Father, lest any one should assert that the same is Father, the same Son. For had He been the Father, He would not have said, He that has seen Me has seen Him. Why then did He not reply, you ask things impossible, and not allowed to man; to Me alone is this possible? Because Philip had said, it suffices us, as though knowing Christ, He shows that he had not even seen Him. For assuredly he would have known the Father, had he been able to know the Son. Wherefore He says, He that has seen Me, has seen the Father. If any one has seen Me, he shall also behold Him. What He says is of this kind: It is not possible to see either Me or Him. For Philip sought the knowledge which is by sight, and since he thought that he had so seen Christ, he desired in like manner to see the Father; but Jesus shows him that he had not even seen Himself. And if any one here call knowledge, sight, I do not contradict him, for, he that has known Me, says Christ, has known the Father. Yet He did not say this, but desiring to establish the Consubstantiality, declared, he that knows My Essence, knows that of the Father also. And what is this? says some one; for he who is acquainted with creation knows also God. Yet all are acquainted with creation, and have seen it, but all do not know God. Besides, let us consider what Philip seeks to see. Is it the wisdom of the Father? Is it His goodness? Not so, but the very whatever God is, the very Essence. To this therefore Christ answers, He that has seen Me. Now he that has seen the creation, has not also seen the Essence of God. If any one has seen Me, he has seen the Father, He says. Now had He been of a different Essence, He would not have spoken thus. But to make use of a grosser argument, no man that knows not what gold is, can discern the substance of gold in silver. For one nature is not shown by another. Wherefore He rightly rebuked him, saying, Am I so long with you? Have you enjoyed such teaching, have you seen miracles wrought with authority, and all belonging to the Godhead, which the Father alone works, sins forgiven, secrets published, death retreating, a creation wrought from earth, and have you not known Me? Because He was clothed with flesh, therefore He said, Have you not known Me?

2. You have seen the Father; seek not to see more; for in Him you have seen Me. If you have seen Me, be not over-curious; for you have also in Me known Him.
[AD 407] John Chrysostom on John 14:8-11
(Hom. lxxiv. 1) Or thus: Philip, because [he thought] he had seen the Son with his bodily eye, wished to see the Father in the same way; perhaps too remembering what the Prophet said, I saw the Lord, and therefore he says, show us the Father. (Isa. 6:1) The Jews had asked, who was His Father; and Peter and Thomas, whither He went; and neither were told plainly. Philip therefore, that he might not seem burdensome, after saying, show us the Father, adds, And it sufficeth us: i. e. we seek for no more. Our Lord in reply does not say, that he asked an impossible thing, but that he had not seen the Son to begin with, for that if he had seen Him, he would have seen the Father: Have I been so long time with you, and yet hast thou not known Me? He does not say, not seen Me, but, not known Me; not known that the Son, being what the Father is, does in Himself fitly show the Father. Then dividing the Persons, He says, He that hath seen Me hath seen the Father; that none might maintain that He was both the Father and the Son. The words show too that even the Son was not seen in a bodily sense. So if any one takes seeing here, for knowing, I will not contradict him, but will take the sentence as if it was, He that hath known Me, hath known the Father. He shows here His consubstantiality with the Father: He that hath seen My substance, hath seen the Father. Whence it is evident He is not a creature: for all know and see the creature, but not all God; Philip, for instance, who wished to see the substance of the Father. If Christ then had been of another substance from the Father, He would never have said, He that hath seen Me, hath seen the Father. A man cannot see the substance of gold in silver: one nature cannot be made apparent by another.

(Hom. lxxiv. 2) Mark the abundant proof of the unity of substance. For He continues; But the Father that dwelleth in Me, He doeth the works. As if He said, My Father and I act together, not differently from each other; agreeing with what He said below: If I do not the works of My Father, believe Me not. But why does He pass from words to works? Why does He not say as we might have expected, He speaketh the words? Because He means to apply what He says both to His doctrine, and to His miracles; or because His words are themselves works.

(Hom. lxxiv. 2) But if this does not suffice to show ray consubstantiality, at least learn it from My works: Or else believe Me for the very works' sake. Ye have seen My miracles, and all the proper signs of My divinity; works which the Father alone worketh, sins remitted, life restored, and the like.

[AD 430] Augustine of Hippo on John 14:8
When Philip said to him, “Lord, show us the Father, and that is enough for us,” he understood well enough that being shown the Father could satisfy him. But if the one who is equal to the Father was not enough for him, how would the Father be enough? And why wasn’t he enough for him? Because he was not seen. Why wasn’t he seen? Because the eye he could be seen with was not yet whole. As for the Lord’s body, which could be seen with these eyes, it was not only the ones who revered him who saw him but also the Jews who crucified him. So if he wanted to be seen in another way, it means he was requiring other eyes. And that is why he gave this reply to the one who said, “Show us the Father, and that is enough for us: Have I been with you all this time, and you do not know me? Philip, whoever sees me also sees the Father.” And to heal the eyes of faith in the meantime, he is first admonished in terms of faith, so that he may be enabled to attain to sight. And in case Philip should assume that God is to be thought of in the same way as he saw the Lord Jesus Christ in the flesh, he immediately added, “Do you not believe that I am in the Father, and the Father is in me?”

[AD 430] Augustine of Hippo on John 14:8-11
(i. de Trin. c. viii) For to that joy of beholding His face, nothing can be added. Philip understood this, and said, Lord, show us the Father, and it sufficeth us. But he did not yet understand that he could in the same way have said, Lord, show us Thyself, and it sufficeth us. But our Lord's answer enlightens him, Jesus saith unto him, Have I been so long with you, and yet hast thou not known Me, Philip?

(Tr. lxx. 1) But how is this, when our Lord said that they knew whither He was going, and the way, because they knew Him? The question is easily settled by supposing that some of them knew, and others not; among the latter, Philip.

(Tr. lxx) When two persons are very like each, we say, If you have seen the one, you have seen the other. So here, He that hath seen Me, hath seen the Father; not that He is both the Father, and the Son, but that the Son is an absolute likeness of the Father.

(Tr. lxx. 3) But is he to be reproved, who, when he has seen the likeness, wishes to see the man of whom he is the likeness? No: our Lord rebuked the question, only with reference to the mind of the asker. Philip asked, as if the Father were better than the Son; and so showed that He did not know the Son. Which opinion our Lord corrects: Believest thou not that I am in the Father, and the Father in Me? as if He said, If it is a great wish with thee to see the Father, at any rate believe what thou dost not see.

(i. de. Trin. 8) He wished him to live by faith, before he had sight, and therefore says, Believest thou not? Spiritual vision is the reward of faith, vouchsafed to minds purified by faith.

(Tr. lxx. 3. and lxxi. 1) He then addresses all of them, not Philip only: The word that I speak unto you, I speak not of Myself. What is, I speak not of Myself, but, I that speak am not of Myself? He attributes what He does to Him, from whom He Himself, the doer, is.

(Tr. lxx. 1, 2) For he that edifieth his neighbour by speaking, doth a good work. These two sentences are brought against us by different sects of heretics; the Arians saying that the Son is unequal to the Father, because He does not speak of Himself; the Sabellians, that the same who is the Father is the Son. For what is meant, they ask, by, The Father that dwelleth in Me, He doeth the works, but, I that dwell in Myself, do these works.

(Tr. lxxi. 2) Philip alone was reproved before.

(Tr. lxxi. 2) Believe then for My works' sake, that I am in the Father, and the Father in Me; for, were we separated, we could not be working together.

[AD 444] Cyril of Alexandria on John 14:8
Philip is anxious to learn, but not very keen in that understanding which is adapted to Divine vision; for else he would never have supposed it possible with bodily eyes to behold in its fulness the Divine nature in spite of the plain declaration of God: No man shall see My Face and live. For even if God in days of old appeared to the saints, as the inspired Scripture tells us, yet no one I think would suppose that the Divine nature was ever made manifest in its full perfection, but rather that it moulded itself into that peculiar fashion of outward appearance which was more specially suitable for each occasion. For example, the Prophets have seen Him in different manners, and their description of God varies greatly. For Isaiah beheld Him in one way, and Ezekiel again in a manner not resembling the wonder recorded in Isaiah. Philip therefore ought to have understood that it was absolutely impossible that he could see the Divine Essence in the flesh and yet in no fleshly form; especially as it was far from wise, with the Likeness and Very Exact Image of God the Father present before his eyes, to seek to penetrate onward to the presence of the Archetype, as though it were not then visible before him and manifested in the most fitting manner. For surely the contemplation of Christ is most fully sufficient as a representation of the Essence of God the Father, unfolding most beautifully and most exactly the marvellous grace of the Kingly Essence from which He was begotten. For the tree is known by its fruit, according to the saying of the Saviour Himself. Seeing therefore that to one who is really thoughtful the contemplation of the Son suffices to represent to us in perfect fulness the nature of Himself and of His Father, we may in all probability reckon the saying of the disciple as out of place; but still it will be found meet to be reckoned within the number of things that deserve the highest praise. For I think we must admire him, and that more than moderately, for saying: show us the Father, and it sufficeth us. For it is as though he had said: "We should acknowledge that we were in the enjoyment of every pleasure, and there would be nothing for us to seek to fill our cup of happiness, if we ourselves also were deemed worthy of the longed-for sight of God the Father." But a man who preferred to every blessing, and to everything that could be imagined to contribute to his pleasure, the sight of God the Father, would surely be acknowledged to be worthy of all admiration. In this sense we shall understand the meaning in this passage, as I think, according to the obvious and simpler view taken by most men. But if it is needful to glance at a more elaborated sense, and perhaps to speak of some of the hidden meanings, we may suppose that Philip both spoke and also thought something on this wise. The leaders of the Jews, and besides them the scribes also and Pharisees, were stung to the quick by the Saviour's wondrous works, and pierced as by stones cast into their heart by His immeasurable proofs of Divine power; they were bursting with jealousy and knew that they were utterly powerless either to perform such wonders themselves or to prevent Him from working them. And so they cavilled at His miraculous acts, seeking to make light of His glory by deceitful words; and running up and down the whole territory of Judaea and Jerusalem itself, they spread reports, at one time that He wrought His signs in the power of Beelzebub; at another time, in the fury of their uncontrollable madness, that He had a devil and knew not what He said. For they kept rebuking the multitudes, saying: He hath a devil, and is mad: why hear ye Him? Moreover [there was another plan of theirs] devised in an insufferable manner to ruin His good reputation; and what this was, I feel it my duty to explain. For they tried to persuade the people, as we showed just now, not to attend to our Saviour's discourses, but to desert His teaching as contrary to the law; hastening to avoid Him as much as possible, and to adhere more firmly to the precepts given as from God by Moses. And on what grounds did they urge this? They said that the great Moses led forth the people of old to meet with God, as it is written, and presented them at the Mount Sinai, showing to them God in the mountain, and preparing them to hear His words, and assuring them most fully and clearly that God was uttering the laws: whereas Christ gave no such proofs of His authority, and did nothing at all of the like. And that this comparison was currently accepted among them thou wilt learn from hence. For thou wilt behold them saying to the man born blind whom the Saviour healed by ineffable power: Thou art His disciple, but we are disciples of Moses. For we know that God hath spoken unto Moses; but as for this Man, we know not whence He is. Those therefore who were arguing with Jewish pleas considered that their argument on this head was difficult to meet and impossible for most men to refute; and, as is probable, they did thereby confound and ensnare many. Bearing this in mind, and thinking that all the gainsaying of the Jews would be stopped if Christ Himself also would show the Father to those who believe on Him, Philip addresses Him in the words: Lord, show us the Father, and it sufficeth us. For conceive him to imply this much: "All things, O Master, that are conducive to faith are effected by Thy authority, and by wonders innumerable one might rebuke the immoderate extravagance of the Jewish gibings. But nothing whatever will fail us, if Thou Thyself wilt show forth to us God the Father; for this will be sufficient for Thy disciples, so as to enable them in the future very successfully to arm themselves in defence with the very arguments of those who put forth the former objections." By applying some such view as this to the passage before us, we shall I think succeed in arriving at the argument suitable to the occasion. For Philip himself invites our attention to this view of ths case, by saying, "It sufficeth us to see God the Father," as though this and this alone were wanting to those who have believed. And the Saviour Himself also may seem to suggest the same idea, by saying in what follows: The words that I say unto you, I speak not from Myself: but the Father abiding in Me, He doeth the works. But the sense we should attribute to this saying will be explained not in the present but in the more suitable and neighbouring passage.
[AD 220] Tertullian on John 14:9
For God the Father none ever saw, and lived. And accordingly it is agreed that the Son of God Himself spake to Moses, and said to the people, "Behold, I send mine angel before thy"-that is, the people's-"face, to guard thee on the march, and to introduce thee into the land which I have prepared thee: attend to him, and be not disobedient to him; for he hath not escaped thy notice, since my name is upon him.

They would have the entire revelation of both Testaments yield to these three passages, whereas the only proper course is to understand the few statements in the light of the many.

I ask whether he is the visible likeness of the invisible God and whether the infinite God can also be presented to view under the likeness of a finite form. For a likeness must necessarily repeat the form of that of which it is the likeness. Let those, however, who want there to be a nature of a different sort in the Son determine what sort of likeness of the invisible God they wish the Son to be. Is it a bodily likeness exposed to the gaze and moving from place to place with human gait and motion? No, rather let them remember that according to the Gospels and the prophets both Christ is a Spirit and God is a Spirit. If they confine this Christ the spirit within the bounds of shape and body, such a corporeal Christ will not be the likeness of the invisible God, nor will a finite limitation represent that which is infinite.

At present I want to see your Father, and you say to me, ‘Have you not known me?’ ” What connection then does this have with the question? Surely a very close one. For if he is that which the Father is, yet continues to be a Son, there is a definite reason for showing in himself the one who begat him. Then to distinguish the persons he says, “He who has seen me has seen the Father,” in case anyone should assert that the same person is Father and Son. For had he been the Father, he would not have said, “He who has seen me has seen him.”

So, he says, was not such a long time sufficient to teach you about my Father and me? And yet you still are looking to see him. If you had known me, you would have known the Father through me and would have not thought that he can be seen with bodily eyes. Since the expression “you still do not know me” seemed not to fit in with the words “show us the Father,” he clearly explains this by saying, “Whoever has seen me has seen the Father. How can you say, ‘Show us the Father?’ ” There is no difference, he says, so that whoever sees me sees the Father himself. There is a perfect similarity between us two that shows the Father himself in me. Very aptly he adds, “How can you say?” as he confirms through his open amazement the words said above. How can you ask me, he says, to show you the Father, if not for the fact that you ignore me completely? Therefore what I said is true, “You neither know my Father nor me. If you had known me, you would have known him too,” because the perfect likeness would have shown him.

[AD 444] Cyril of Alexandria on John 14:9
How sayest thou then, show us the Father?

"Thou mightest, Philip," He would say, "have beheld the glory of the Father in Me, and from what I am have perceived the nature of My Parent: for I have appeared in My true character as a Very and Exact Image and as a Perfect Likeness of His essence, bearing engraved on Myself the entire nature of God the Father. What additional manner of Divine vision other than this couldst thou ask for, at least if thou wouldst display thy ability to estimate things in true proportion; or tell Me what kind of contemplation thou dost require? Dost thou really suppose that a better and fuller manifestation was granted to the men of former times, when I came down on Mount Sinai in a vision of fire?" For this above all else was the greatest and most usual boast of the Jews.

This we may in all probability suppose to have been the meaning of Christ's answer. We must now, I conceive, feel it our duty to state in all boldness that the manifestation of the miracles of our Saviour Christ was a better guide to the knowledge of God the Father than the vision that appeared on Mount Sinai. For thus thou wilt see that Philip, when the true Image was before his eyes, was in no way constrained to ask for that other sight of God the Father which on Mount Sinai was granted to those of former time. For there the Lord descended, as it is written, in a form of fire, while the Israelites were looking on. But no one could, I think, thereby be made to advance to a right conception concerning God, or to ascend with one bound to a fitting comprehension of the Godhead. For how by means of fire as an image could we be led to realise the existence of God the Father as the Archetype [thereby shadowed forth]? For God is naturally good, and moreover is a Creator, calling previously non-existent things into being, bringing together the universe into consistence, and quickening all things: He is also Wisdom and Power, kind, compassionate, and merciful. And none of these attributes belong to fire. For no one would suppose, at least if he were gifted with sense, that fire was kind and compassionate to men; nor would any one soberly maintain that it was a creative influence, endowed with wisdom and the power of bestowing life. If this be so, tell me how any one could possibly from a vision of fire gather any ideas concerning the true nature of the Godhead. Or how could one behold in a mirror darkly any of those attributes that are inherent in it? What then, one may say, was the ground or reason that induced God to declare Himself in the form of fire on Mount Sinai? We shall answer that as the children of Israel were, at that moment above all others in their career, beginning their education in the way of godliness, and were about to draw up the law which was to be observed as a strict rule to govern their own lives; it was most especially needful that God should appear as a Chastiser and a Terrible One to them, so that transgressors might be able to realise that they had to do with a Fire. Therefore surely it was that the great Moses also in speaking to the children of Israel said: Our God is a consuming Fire. And we should not at all be inclined to say that it was in order to exhibit to us the nature of God that the very wise writer thus compared Him to fire, but that he bestowed this title on God from the fact that, owing to His excessive hatred of wickedness, God shrinks not from wasting and consuming, like an all-devouring fire, those who despise Him. Therefore it is not in consequence of what He is in His nature that God makes Himself known in a vision of fire: but it was found to conduce to the profit of those who listened, that He should be thus named, and that He should have then appeared as fire. Let us pass now to that true and most exact vision of the Father granted to us in the Son. For we shall see Him to be an Image of the One Who begat Him, if we gaze intently with the eye of our minds on the extraordinary powers that are displayed in Him. Goodness belongs naturally to God the Father, and the same we shall find in the Son. For surely He is good, Who endured so great humiliation for our sakes, coming into the world to save sinners, and laying down His life for them. Similarly the Father is powerful, and so it is with the Son. For what power could be greater than that which commanded even the elements themselves, rebuking the sea and the winds, and transforming the nature of substances at His will; bidding the leper be cleansed, and giving sight to the blind: and all with God-befitting authority? The Father is in His nature Life: the Son also is equally Life, quickening those who have been turned to corruption, overthrowing the power of death, and thereby raising the dead to life. Rightly then does he say to Philip: He that hath seen Me hath seen the Father. "For whereas," He would say, "thou mightest in Me and through Me behold very clearly My Father, what other manner of Divine vision dost thou ask for, when thou hast received a far better one than that vouchsafed to the men of former time, and hast met with a most true Likeness of the Father, namely Mine own Self?"
[AD 444] Cyril of Alexandria on John 14:9
Jesus saith unto him, Have I been so long time with you, and dost thou not know Me, Philip? He that hath seen Me hath seen the Father.

In an unexpected way He convicts the disciple of ignorance. For the less easily discernible portions of the meanings implied, in the apprehension of which our mental faculties are necessarily put to a more subtle test, will certainly, although possibly not in any short period yet still in a longer extension of time, be grasped by those who are desirous to learn, and will explain themselves most clearly; and those whose minds are not hardened and whose knowledge is unobstructed, may at once be expected to perceive such meanings and accept them with perfect ease. "What is it therefore," He seems to say," that hinders you, O Philip, from arriving at perfection of knowledge of Myself? Tell Me. For although so long a time has elapsed since I have been with you as to suffice for a perfect knowledge of all that it was needful for thee to learn, nevertheless thou art still in doubt, or rather art convicted of absolute ignorance, as to Who I am by nature, and whence I come; and yet thou findest Me to be the Creator of all that is more especially admired in thy sight. How was it that thou didst not know that he who hath seen Me hath seen the Father? Thou supposest that the Jews of old saw the Divine Nature on Mount Sinai, and heard it speaking in delivering the laws that govern men's conduct; but not yet hast thou realised that through Me and in Me thou hast seen the Father. For he that hath seen Me hath seen the Father." And to show my hearers that it is no corporeal contemplation that Christ here indicates, needs I think not many words. For no thoughtful person would ever maintain that the Divine Nature can be made an object of corporeal vision; nay, no one could endure to behold with the eyes of the body that which is now apprehended dimly as in a mirror: for we see darkly, and I believe that even the man who boasts of the very highest knowledge has but a faint idea concerning God.

But this also we must say to the enemies of the truth, who are profuse in their railings against us, or rather against the very essence of the Only-begotten. For if it is untrue that the Son is of the very essence of God the Father, so as to be by generation That which He is, namely in His nature and in very truth God; and if He is made illustrious by the mere addition to Himself of features that were not originally His own, so that He shines as it were by reflected light from glories bestowed upon Him, and not by His own natural lustre, while appearing all the while as a true Likeness of the Father and an unchanging Image of God; then surely in the first place He could not be in His nature a Son, or even in any true sense an Offspring, but He must be either a created object like unto ourselves, or some other being standing in a similar relation: and this much being admitted and accepted as true, we shall then, it seems, have established this consequence also, that the Father could never be really and naturally a Father, but only so in will and in semblance, just as He is reckoned a Father of us also. And what will be the natural sequence of this? We shall still necessarily have to acknowledge a Trinity: only no longer do we express any belief whatever in the Holy Trinity, but rather in three utterly distinct Persons, each having nothing essentially in common with any other, each one of those named receding as it were into the special peculiarity of His own nature, each totally separate from the other. For the weightiness of the subject forces us to speak even more firmly still on the point. And if we allow that this is true, and confess that it follows as we have said, and admit that the Son is utterly different from the essence of God the Father, surely then Christ will be speaking falsely in the words: He that hath seen Me hath seen the Father. For since the Father is from the beginning in His nature God, how could the Son, although not being (according to the view of these heretics) in His nature God, show forth the Father in Himself? For how shall we behold the Uncreated in the created? And in one who once was not (according to their theory), how could any man possibly behold Him Who was from all eternity? For let not any of these blasphemers tell me, in his sophistical declamations against the power of truth, that because Christ is endued with the glory of God and His power and wisdom and good and omnipotence, so that He can bring into being things that never before existed, therefore He is also an Image of Him: but first let such an one prove whether Christ does not display Himself as in His nature God, and that so irrefutably that there is nothing which impairs the universal and absolute resemblance of the Image to the Archetype. And if he hesitates in perplexity and is unwilling to prove this, we will in the next place ask him to tell us what explanation will allow of one who (according to their accursed notions) is not in His nature God, being enabled to fulfil the works that belong to the Godhead: for this is what they mean by saying that He bears the Image of the Father. For if the Son, without possessing as His own a power sufficient for the purpose, borrows the power from the Father, and is by Him supplied with wisdom and might, so as to be able to perform actions which we shall allow to be beyond the power of any nature save that of the Father alone; then in so doing He will be falsely representing the Image and the Likeness. And if we refuse to admit that He (being of the nature we have just been describing) is guilty of falsehood, and accept the truth of His words, we shall then find ourselves convicted of wronging the glory of God the Father in a manner that I will now explain. We are constrained to admit one of two things: either He falsely represents the Image of God the Father, in that He possesses not in Himself the might sufficing for His acts, but is supplied therewith from another, whereas it is not so with the Archetype; or else, if it is true as He says that in Him the Father is seen by us, and that there is really nothing whatever that disfigures or obscures or perverts His perfect similarity, it is absolutely necessary, willingly or unwillingly, to admit that the Father Himself holds His power as something received from another. For in this way He willed to display to us Himself in the Image of His own nature and of His glory.

"Is it possible then," one might go on to say to these heretics, "that you do not perceive whither your theory, when once it quits the safe path, will lead you on, and into what an abyss of error it will plunge those who have held such views?" "But," say they, "surely it is possible that the Son, although a created being, may yet fulfil the works whereof by His nature He is capable, and so advance the glory of God the Father?" Now what suggestion can appear more impious than this? If this be as they say, there can no longer be any superiority or any higher dignity by which God excels His creatures, if even one of them is to be invested with the glory and power of the Godhead. For let no one be so excessively deranged in mind as to suppose that he is imagining and uttering a marvellous and magnificent compliment concerning the Son in thinking or saying that "He is a creature, but not as one of the creatures." Let him be well assured that he is thus in no small degree disparaging His glory. For the question is not whether His nature is specially superior beyond all other creatures, but whether He is at all a created being. For how could He avoid the consequences of being a creature, even though He were the noblest of all creatures? And if the glory of the Son is disparaged by saying that He was brought into existence, why do they vainly advance (to heal as it were His offended dignity) the statement that He was created in the highest of all possible ranks? It follows therefore that we shall offer insult to the essence of God the Father if we bestow such power on the Son, supposing the Son (according to their ignorant and unskilful reasoning) is Himself a created being. And we shall not tolerate them when they tell us that the Son performs the acts of the Godhead, though Himself in His nature a creature, so as to glorify God the Father. If they can prove as much from the Divine Scripture, let them bring forward their citations, and let them observe the sayings of the holy writers in all sincerity: but if these are inventions of their own brains, and if they have themselves manufactured their arguments in this matter, we shall salute them with the words: Woe to those who prophesy after their own heart! For we shall allow that the Father ever is desirous of whatsoever He knows will maintain in integrity His Divine glory and preserve the absolute truth of the declarations made concerning Himself. And so we shall now bid farewell to the ignorant suggestions of those heretics and pass on to the real truth concerning Christ, believing that He is in truth begotten as Son of the essence of God the Father, and that He is in His nature God of God. For thus He speaks in perfect truth, in that He is both the Very Image and the Likeness of God the Father, when He says: He that hath seen Me hath seen the Father.

"With what view else did He so emphatically dwell on this point, if it Were not to clear up that which He wished men to understand-namely, that He was the Son? And then, again, by saying, "Believest thou not that I am in the Father, and the Father in me," He laid the greater stress on His question on this very account, that He should not, because He had said, "He that hath seen me, hath seen the Father," be supposed to be the Father; because He had never wished Himself to be so regarded, having always professed Himself to be the Son, and to have come from the Father.

The words of the Lord, “I am in the Father and the Father is in me,” confuse many minds, and this is only natural since the powers of human reason cannot provide them with any intelligible meaning. It seems impossible that one object should be both within and without another, or that—since it is laid down that the beings of whom we are treating, although they do not dwell apart, retain their separate existence and condition—these beings can reciprocally contain one another so that one should permanently envelope and be permanently enveloped by the other whom yet he envelopes.

He is not falsely concealing the fact that he is God the Father. He is not a single person who hides his features under a mask so that we might imagine that two are present. He is not a solitary being, now posing as his own Son, and then again calling himself the Father, adorning the one unchanging nature with varying names.… It is the height of impiety to believe that Father and Son are two gods.

These attributes must be in the Image to make it true that whoever “has seen” the Son “has seen the Father.” If the Son is not all this, but, as the Arians consider, he is originate and not eternal, this is not a true image of the Father, unless indeed they give up shame and go on to say that the title of image, given to the Son, is not a token of a similar essence, but his name only.

The Father that dwells in Me, He does the works.

How, beginning with words, does He come to works? For that which naturally followed was, that He should say, the Father speaks the words. But He puts two things here, both concerning doctrine and miracles. Or it may have been because the words also were works. How then does He them? In another place He says, If I do not the works of My Father, believe Me not. John 10:37 How then says He here that the Father does them? To show this same thing, that there is no interval between the Father and the Son. What He says is this: The Father would not act in one way, and I in another. Indeed in another place both He and the Father work; My Father works hitherto, and I work John 5:17; showing in the first passage the unvaryingness of the works, in the second the identity. And if the obvious meaning of the words denotes humility, marvel not; for after having first said, Do you not believe?

Among all the words said so far, especially here, he clearly shows that he talks about their likeness. Indeed, in the same way, by turning the speech to the Father and him, he reveals the perfect likeness of their nature, so that, as the Father lives in him, and he in the Father, a perfect likeness can be shown in each of them. Then he proves and confirms his words by saying, “The words that I say to you I do not speak on my own.” If you do not believe, he says, in these words, know that so perfect is the conformity of nature, ideas, and virtue that there is no difference in the words either. Whatever I say is in common, and do not only speak on my own. The Father who dwells in me does his works. It would have been opportune to add, “My Father speaks through the words: I do not speak.” But he had said above, “The words that I say,” and here, “The Father does his works,” in order to show that the nature is common, the words are common and the works are common as well. From this it is evident that through the words, “I do not speak on my own,” he does not signify an inferior state, but a perfect communion and an inseparable union. And this appears especially from the context.

[AD 430] Augustine of Hippo on John 14:10
1. Give close attention, and try to understand, beloved; for while it is we who speak it is He Himself who never withdraws His presence from us who is our Teacher. The Lord says, what you have just heard read, The words that I speak unto you, I speak not of myself: but the Father, that dwells in me, He does the works. Even His words, then, are works? Clearly so. For surely he that edifies a neighbor by what he says, works a good work. But what mean the words, I speak not of myself, but, I who speak am not of myself? Hence He attributes what He does to Him, of whom He, that does them, is. For the Father is not God [as born, etc.] of any one else, while the Son is God, as equal, indeed, to the Father, but [as born] of God the Father. Therefore the former is God, but not of God; and the Light, but not of light: whereas the latter is God of God, Light of Light.

2. For in connection with these two clauses,— the one where it is said, I speak not of myself; and the other, which runs, but the Father that dwells in me, He does the works,— we are opposed by two different classes of heretics, who, by each of them holding only to one clause, run off, not in one, but opposite directions, and wander far from the pathway of truth. For instance, the Arians say, See here, the Son is not equal to the Father, He speaks not of Himself. The Sabellians, or Patripassians, on the other hand, say, See, He who is the Father is also the Son; for what else is this, The Father that dwells in me, He does the works, but I that do them dwell in myself? You make contrary assertions, and that not only in the sense that any one thing is false, that is, contrary to truth, but in this also, when two things that are both false contradict one another. In your wanderings you have taken opposite directions; midway between the two is the path you have left. You are a far longer distance apart from each other than from the very way you have both forsaken. Come hither, you from the one side, and you from the other: pass not across, the one to the other, but come from both sides to us, and make this the place of your mutual meeting. You Sabellians, acknowledge the Being you overlook; Arians, set Him whom you subordinate in His place of equality, and you will both be walking with us in the pathway of truth. For you have grounds on both sides that make mutual admonition a duty. Listen, Sabellian: so far is the Son from being the same as the Father, and so truly is He another, that the Arian maintains His inferiority to the Father. Listen, Arian: so truly is the Son equal to the Father, that the Sabellian declares Him to be identical with the Father. Do thou restore the personality you have abstracted, and thou, the full dignity you have lowered, and both of you stand together on the same ground as ourselves: because the one of you [who has been an Arian], for the conviction of the Sabellian, never lets out of sight the personality of Him who is distinct from the Father, and the other [who has been a Sabellian] takes care, for the conviction of the Arian, of not impairing the dignity of Him who is equal with the Father. For to both of you He cries, I and my Father are one. When He says one, let the Arians listen; when He says, we are, let the Sabellians give heed, and no longer continue in the folly of denying, the one, His equality [with the Father], the other, His distinct personality. If, then, in saying, The words that I speak unto you, I speak not of myself, He is thereby accounted of a power so inferior, that what He does is not what He Himself wills; listen to what He also said, As the Father raises up the dead and quickens them, even so the Son quickens whom He will. And so likewise, if in saying, The Father that dwells in me, He does the works, He is on that account not to be regarded as distinct in person from the Father, let us listen to His other words, What things soever the Father does, these also does the Son likewise; and He will be understood as speaking not of one person twice over, but of two who are one. But just because their mutual equality is such as not to interfere with their distinct personality, therefore He speaks not of Himself, because He is not of Himself; and the Father also, that dwells in Him, Himself does the works, because He, by whom and with whom He does them, is not, save of [the Father] Himself. And then He goes on to say, Believe ye not that I am in the Father, and the Father in me? Or else believe me for the very works' sake. Formerly it was Philip only who was reproved, but now, it is shown that he was not the only one there that needed reproof. For the very works' sake, He says, believe ye that I am in the Father, and the Father in me: for had we been separated, we should have been unable to do any kind of work inseparably.

3. But what is this that follows? Verily, verily, I say unto you, He that believes in me, the works that I do shall he do also; and greater works than these shall he do; because I go unto my Father. And whatsoever you shall ask in my name, that will I do, that the Father may be glorified in the Son. If you shall ask anything in my name, I will do it. And so He promised that He Himself would also do those greater works. Let not the servant exalt himself above his Lord, or the disciple above his Master. He says that they will do greater works than He does Himself; but it is all by His doing such in or by them, and not as if they did them of themselves. Hence the song that is addressed to Him, I will love You, O Lord, my strength. But what, then, are those greater works? Was it that their very shadow, as they themselves passed by, healed the sick? Acts 5:15 For it is a mightier thing for a shadow, than for the hem of a garment, to possess the power of healing. Matthew 14:36 The one work was done by Christ Himself, the other by them; and yet it was He that did both. Nevertheless, when He so spoke, He was commending the efficacious power of His own words: for it was in this sense He had said, The words that I speak unto you, I speak not of myself; but the Father that dwells in me, He does the works. What works was He then referring to, but the words He was speaking? They were hearing and believing, and their faith was the fruit of those very words: howbeit, when the disciples preached the gospel, it was not small numbers like themselves, but nations also that believed; and such, doubtless, are greater works. And yet He said not, Greater works than these shall you do, to lead us to suppose that it was only the apostles who would do so; for He added, He that believes in me, the works that I do shall he do also; and greater works than these shall he do. Is the case then so, that he that believes in Christ does the same works as Christ, or even greater than He did? Points like these are not to be treated in a cursory way, nor ought they to be hurriedly disposed of; and, therefore, as our present discourse must be brought to a close, we are obliged to defer their further consideration.
[AD 430] Augustine of Hippo on John 14:10
The Father was not born of the Virgin, and yet this birth of the Son from the Virgin was the work of both Father and Son. The Father did not suffer on the cross, and yet the passion of the Son was the work of both Father and Son. The Father did not rise again from the dead, and yet the resurrection of the Son was the work of both Father and Son. You have the persons quite distinct, and their working inseparable. So let us never say that the Father worked anything without the Son, the Son anything without the Father. Or perhaps you are worried about the miracles Jesus did, in case perhaps he did some that the Father did not do? Then what about “But the Father abiding in me does his works”?

Source: SERMON 52.14
[AD 430] Augustine of Hippo on John 14:10
So then, with all these ways of speaking we still have to understand that the activities of the divine three are inseparable, so that when an activity is attributed to the Father he is not taken to engage in it without the Son and the Holy Spirit. And when it is an activity of the Son, it is not without the Son and the Holy Spirit. And when it is an activity of the Son, it is not without the Father and the Son. That being the case, those who have the right faith, or better still the right understanding as far as they can, know well enough that the reason it is said about the Father, “He does the works,” is that the works have their origin in the one from whom the co-working persons have their very existence. The Son, you see, is born of him, and the Holy Spirit proceeds primarily from him of whom the Son is born, being the Spirit common to them both.

[AD 444] Cyril of Alexandria on John 14:10
The words that I speak, I speak not from Myself: but the Father abiding in Me Himself doeth the works.

"If," He would say, "My Father had spoken anything to you, He would have used words no other than these which I now speak. For so great is the equality in essence between Myself and Him, that My words are His words, and whatsoever I do may be believed to be His actions: for abiding in Me, by reason of the exact equivalence in essence, He Himself doeth the works." For since the Godhead is One, in the Father, in the Son, and in the Spirit, every word that cometh from the Father comes always through the Son by the Spirit: and every work or miracle is through the Son by the Spirit, and yet is considered as coming from the Father. For the Son is not apart from the essence of the Father, nor indeed is the Holy Ghost; but the Son, being in the Father, and having the Father again in Himself, claims that the Father is the doer of the works. For the nature of the Father is mighty in operation, and shines out clearly in the Son.

And one might add to this another meaning that is involved, suggested clearly by the principles that underlie the Incarnation. He says: I speak not of Myself, meaning "not in severance from or in lack of accordance with God the Father." For since He appeared to those who saw Him in human form, He refers His words back to the Divine nature, as speaking in the Person of the Father; and the same with His actions: and He almost seems to say: "Let not this human form deprive Me of that reverent estimation which is due and befitting to Me, and do not suppose that My words are those of a mere man or of one like unto yourselves, but believe them to be in very truth Divine, and such as befit the Father equally with Myself. And He it is Who works, abiding in Me: for I am in Him, and He is in Me. Think not therefore that a mighty and extraordinary privilege was granted to the men of former days, in that they saw God in a vision of fire, and heard His voice speaking unto them. For ye have in reality seen the Father through Me and in Me; since I have appeared among you, being in My nature God, and have come visibly, according to the words of the Psalmist. And be well assured that in hearing My words, ye heard the words of the Father; and ye have been spectators of His works, and of the might that is in Him. For by Me He speaks, as by His own Word; and in Me He carries out and achieves His wondrous works, as though by His own Power."

And so I suppose that no reasonable theory would ever separate Him Who is the Word of the Father and the mighty Power of His essence, from the essence of the Father. Eather would every one freely confess that the Word ever was from the beginning in His nature contained in the Father's essence, every one at least who is anything but distraught in mental perplexity.
[AD 444] Cyril of Alexandria on John 14:10
Believest thou not that I am in the Father and the Father in Me?

"I indeed, O Philip," He would say, "in depicting in Myself the nature of My Father, am the Image of His essence, moulded as that implies after His likeness, not (as might be supposed) by the bestowal of glories that once were not Mine, nor even by the reflected brilliancy of Divine endowments that once were unfamiliar but have been granted from without: but rather in My own nature are contained the qualities peculiar to My Father; and whatsoever He may be, that in very truth am I, in regard to sameness in essence. To this thou wilt surely reply: for it seems thou didst not go on to realise that I am in the Father, and the Father in Me. And yet the force of my words shall constrain thee henceforth, even in spite of thyself, to acknowledge thy assent to this. Therefore, whatsoever I say is spoken as the words of the Father; and whatsoever I do, is done by the Father also." And Christ says this, not as one making use of the words of another, nor even as speaking in the office and capacity of a prophet to interpret the commands that came from the Father above: for the prophets ever spake, not their own words, but the words which they received by inspiration from God. Again, He attributes to His Father the successful performance of His miracles, not implying that He works His wonders by a power not His own, as did for instance those Apostles who said to the people: "Give not heed to us, as though by our own power or godliness we had healed the sick man." For the saints are wont to use no power of their own in working their miracles, but rather the power of God: for they appear as ministers and servants, showing forth the words and also the works of God. But since the Son is Consubstantial with the Father, differing from Him in no respect except as to distinct personality, He says that His own words are those of the Father, since the Father could in no wise make use of words differing from those of the Son. And further, thou wilt understand the same to be signified in the majesty of His works. For since the Father could never by any possibility carry into effect any work without the Son's knowledge and co-operation, Christ attributes His works to His Father. For consider Him as saying more clearly this: "I am in all respects like to Him Who begat Me, and an Image of His essence; not merely adorned with the outward appearance of a glory that is not Mine, but, owing to the identity of essence, containing within Myself My Father in all His fulness."
[AD 444] Cyril of Alexandria on John 14:10
If, he would say, my Father had spoken anything to you, he would not have used any other words than these that I am now speaking. For so great is the equality in essence between myself and him that my words are his words, and whatever I do may be believed to be his actions. For, because he “abides in me,” by reason of the exact equivalence in essence, he himself does the works.

Every work or miracle is through the Son by the Spirit, and yet it is considered as coming from the Father. For the Son is not apart from the essence of the Father, nor indeed is the Holy Spirit.

He almost seems to say, Do not let this human form deprive me of that reverent estimation that is due and befitting to me, and do not suppose that my words are those of a mere human or of one like yourselves. Rather, believe them to be in very truth divine words that would be just as fitting for the Father as they are for me. And he is the one who works, “abiding in me.” For I am in him, and he is in me. Do not think therefore that a mighty and extraordinary privilege was granted to the people of former days because they saw God in a vision of fire and heard his voice speaking to them.

If, indeed, He meant the Father to be understood as the same with the Son, by saying, "He who seeth me seeth the Father," how is it that He adds immediately afterwards, "Believest thou not that I am in the Father, and the Father in me? " He ought rather to have said: "Believest thou not that I am the Father? "With what view else did He so emphatically dwell on this point, if it Were not to clear up that which He wished men to understand-namely, that He was the Son? And then, again, by saying, "Believest thou not that I am in the Father, and the Father in me," He laid the greater stress on His question on this very account, that He should not, because He had said, "He that hath seen me, hath seen the Father," be supposed to be the Father; because He had never wished Himself to be so regarded, having always professed Himself to be the Son, and to have come from the Father.

His power belonged to his nature, and his working was the exercise of that power. In the exercise of that power, then, they might recognize in him the unity with the Father’s nature. To the extent that anyone recognized him to be God in the power of his nature, that person would come to know God the Father who was present in that mighty nature. The Son, who is equal with the Father, showed by his works that the Father could be seen in him so that when we perceived in the Son a nature like the Father’s in its power, we might know that in Father and Son there is no distinction of nature.

[AD 407] John Chrysostom on John 14:11
You ought not, when you hear of 'Father' and 'Son,' to seek anything else to the establishing of the relationship as to Essence, but if this is not sufficient to prove to you the Condignity and Consubstantiality, you may learn it even from the works. Had the, he that has seen Me, has seen My Father, been used with respect to works, He would not afterwards have said,

Or else believe Me for the very works' sake. And then to show that He is not only able to do these things, but also other much greater than these, He puts them with excess. For He says not, I can do greater things than these, but, what was much more wonderful, I can give to others also to do greater things than these.
[AD 444] Cyril of Alexandria on John 14:11
Or else believe for the very works' sake.

In these words He distinctly says that He could never have worked out and achieved those miracles which were characteristic of the Divine nature alone, if He had not been Himself essentially of that nature. And see on what sure grounds and also with what truth He makes this declaration. He does not claim credence for His words alone, although He knew no deceit, so much as for His actions. And why this is so I will tell you. There would be nothing to prevent any man, however mad and however foolish, from falsely using God-befitting words and speeches, and uttering such expressions in a most reckless manner: but who could ever display a God-befitting power of action? And to whom of created beings will the Father grant that glory which is especially His own? Do we not always say that the power of doing all things and the possession of an all-supreme might is the glory of God alone, attaching to no other being, at least to no one ever numbered among the creatures of God? Therefore it is that Christ, wishing to give a proof of His Divinity resting on cogent and unquestionable arguments, urged them to believe the evidence of His actual works that He was in the Father, and that the Father again was in Him: that is, that he bears in His own substance the nature of the Father, as being His very own Offspring and most truly His Fruit, and appearing in natural relation to Him as Son to Father. But while the Church of Christ, in perfect confidence in the rightness of her teaching, holds in this form her doctrine concerning the Only-begotten, on the other hand the ungodly heretics have attempted to seduce to a different belief those who follow after and attend to their pernicious teachings. For the miserable creatures are furious in their outcries against Christ, and consider one another not to provoke unto godliness, but to the end that each one may appear more godless than another, and may utter something yet more unseemly. For since they drink the wine of Sodom and gather the bitter clusters of Gomorrah, because they receive not from the Divine Spirit their knowledge concerning Him, nor yet by revelation from the Father, but from the dragon himself; they can conceive in their minds nothing that is sound and right, but they utter sayings which bring to absolute wretchedness the souls of those who hear them, hurling them down to Hades and the abyss below. They venture moreover to publish these opinions in books, thus stereotyping their own wickedness for all time. It ought to have been sufficient for us to have said just so much on the present passage as would have been likely to benefit those who may chance to read it, by way of establishing in absolute accuracy the true conception concerning the Son, without making any allusion whatever to the heretical writings. But as it is in no way improbable that some persons of feeble intelligence may, on chancing to meet with their miserable sayings, be carried away by them; I considered it necessary to put an end to the harm that might result from their foolish talk, by exposing the utter weakness of the slanders they wish to raise in their vehement attack on the Son, or rather, for that is the truer way of putting the case, on the whole Divine nature.

I happened then to meet with a pamphlet of our opponents, and on investigating what they had to say on the text now before us, I found, in the course of reading it, these words used after certain others: "The Son therefore being essentially encompassed by the Father, has within Himself the Father, and it is the Father Who utters the words and accomplishes the miracles. This is the interpretation of His words: The things that I speak unto you, I speak not from Myself; but the Father abiding in Me, He doeth the works"

Such are the exact expressions of the author's quibbling jugglery. Now since it is my duty to mention this view, which is opposed to the language of Scripture, and which may very well perplex an inexperienced mind, I make this assertion. As to their phrase, that "the Son is essentially encompassed by the Father," I do not in the least understand what in the world it means, or what it signifies,----I speak the truth, as I feel it my duty to do,----so great is the obscurity of the expression. The real sense of the words seems ashamed of itself, and inclined to veil itself in overmuch dimness, not daring to explain itself openly and clearly. For even as he that doeth ill hateth the light, and cometh not to the light, lest he should be improved, according to the Saviour's word; even so every argument with an ill tendency is wont to move through dark ideas, and will not go towards the light of plain speaking, lest the meanness of its inherent unsoundness should be reproved. What then may we suppose to be the meaning of the Son's being "essentially encompassed by the Father?" For I will spare no pains to discover reasonings which may sift in |268 every possible way the real import of that which is here so dimly expressed, and which perhaps shrinks from being understood lest it may then reveal the folly of its author. If then the meaning be this, that the Son, appearing in the essence of the Father as Consubstantial with Him, displays also in His own Person the Father brilliantly shining in the nature of His Offspring, we also will assent to the truth of the statement: still, the use of the word "encompass" would perchance do more than a slight injustice in its application to the Son. But if this be not the meaning,----and surely it cannot be, for never would it be admitted that the Son is begotten of the essence of the Father by one who has vomited such blasphemy against Him, insisting that like some finite body the nature of the Son is enclosed within that of the Father,----certainly such an one will be convicted of evident blasphemy, and will be shown to be full of the most excessive madness. For while admitting in words that the Son is God, they endeavour most illogically to invest Him with properties peculiar to [created] bodies. For the being parted off by a boundary line and separated by a definitely conceived measure, the starting from a fixed origin and ceasing at a fixed limit, all this surely implies existence conditioned by place and size and fashion and form. And these are surely attributes of [created] bodies. Shall we not then in this way be thinking of Him Who is above us as though He were on a level with us as one of ourselves? Would He not then be a brother to the rest of creation, having henceforth nothing in Himself by way of superiority to it, inasmuch as this theory has come to speak of His existence as merely finite? And, being so, at least according to the foolish supposition of our opponents, why did He vainly reproach us in the words: Ye are from beneath; I am from above, and again: Ye are of this world; I am not of this world? For in saying that He Himself is "from above," He does not simply mean that He came from heaven: else, how would He excel the holy angels, since we shall find that they also are "from above," if we interpret the meaning in a merely local sense? But He signifies that He is the Offspring of that essence which is from above, and which is more excellent than all else in the universe. How then after this can He be speaking the truth, if He possesses the peculiar attributes of [created] bodies in common with all creation, and is "encompassed" by the Father, even as those things that are brought into existence out of nothing? For of course we are ready to agree that no created thing can be situated outside of the Father. And the inspired Psalmist also, speaking surely by the Spirit deep truths and hidden mysteries, says that the Son is all-pervading, attesting thereby His incorporeal and illimitable nature, and that as God He is confined to no one locality. For his words are: Whither can I go from Thy Spirit, and whither can I fly from Thy Presence? If I ascend into heaven, Thou art there; if I descend into Hades, Thou art present: if I take my wings in the morning, and go unto the uttermost parts of the sea, even there also Thy hand shall guide me, and Thy right hand shall hold me. But these heretics, in utter recklessness ranging their own opinions in antagonism to the words of the Spirit, subject the Only-begotten to limitations and boundaries, although they ought to have understood the matter from the cogent and instructive reasoning of this Scripture. For if He has filled the heavens and the uttermost parts of the earth, and therefore also the regions of Hades, is it not excessively unreasonable to apply to Him the word "encompassed," without reflecting that if His Presence, that is, if the Spirit----for the Psalmist calls the Spirit the Presence of the Son----fills all things, it is inconceivable that Christ Himself should be "encompassed" within any boundary, even though it be in the substance of God the Father? Nay, it will be no less outrageous to limit within a confined space that which is incorporeal than to include in a measure that which exists in no finite form. For to say that He is "essentially encompassed by God the Father" is surely nought else than to imply that His essence is finite, exactly like any individual thing of the works that were made by Him: and these we shall safely and truly allow to be capable of being "encompassed ": for they are [created] bodies, even though perchance not all such as ours.

But besides, there is this also to be thought of. If we maintain that it is necessary that whatever is enfolded by anything lies entirely within the limits of that which is said to "encompass" it, will it not certainly follow that we should think of that which is "encompassed" as something less than that which "encompasses" it, and should speak of it as limited thereby, and as it were enclosed within the compass of that which is greater than itself? What sayest thou now, my friend? Here we have Christ presenting Himself before us as a Likeness of God the Father, and plainly saying: He that hath seen Me hath seen the Father, and again straightway adding: I am in the Father, and the Father is in Me. Let us assume then that He means, as you would understand Him to say, that "although I am the Very Image and Likeness of My Father, yet I am essentially encompassed by Him." Surely it is acknowledged by all men that He would have us hold just such ideas concerning the Father as we would conceive concerning Himself also. Therefore it would follow that the Father also is subject to limitation, for He is in the Son: and let the heretic search if he will and find out who or what is greater than the Father; I should deem it impious to express or even to conceive such an idea. The Son can never be a Likeness of the Father in one way and not so in another. For if He has in Himself anything at all that would alter or interfere with His resemblance in all points, He would be, as a consequence of that, a partial and not a perfect Likeness. But where could you show us the Holy Scripture teaching such a doctrine as this? For most certainly we are not going to be led astray by your words so as to reject the plain truth of the Sacred statements. And I wonder how it is they did not shrink in dismay from adding to their former arguments the following: "Just as Paul had Christ speaking in him and effecting the mighty deeds, exactly in the same way also the Son had the Father speaking in Him and working the miracles; wherefore He says: Believe that I am in the Father, and the Father in Me: or else believe Me for the very works' sake." After this, who will any longer allow the name of Christian to one who holds such views and thinks such thoughts concerning Christ? For behold how very evidently he maintains that Christ is no longer truly God: recklessly He invests Him with the limitations properly characteristic of creatures, proclaiming Him to be a sort of God-bearer, or one who participates in God, rather than One begotten God of God. To put it briefly, his aim is throughout the utter severance of Christ, in every way and in every respect, from the essence of God the Father; and to cut Him off altogether from that intimate relationship in nature and essence which He has with God His own Father.

Now what could be conceived to surpass such views as these in the immense amazement they are calculated to excite? How could one refrain from shedding in torrents uncontrollable tears of love over men so utterly abandoned to ungodliness, as though they were already dead and perished? One might say, and that very appropriately: Who will give to my head water, and to mine eyes a fountain of tears, and I will weep for this people day and night? For over those who have chosen to think such thoughts as these, one might fitly shed innumerable tears. But since it is by means of the doctrines of the truth that I conceive we ought to refute their slanders, for the sake of that which is profitable to simple folk, come now, and let us answer them by saying that we have been very jealous for the Lord. For assuredly, my friends, the inspired Paul or any other among the saints, while they had in themselves Christ tabernacled in their hearts by the Spirit, very easily did such things as seemed good unto God, and appeared as workers of miraculous deeds. It is an established fact therefore, and one that thou wouldst thyself admit to be true, that being really human in nature, and different in essence from the Holy Spirit of Christ that dwelt within them, they were fearers of God, and were glorious by reason of the grace bestowed on them by Christ. And thou wilt altogether agree with us in saying that they were at one time destitute of this gift, and were called thereunto when it seemed good to God, Who directs all things well, that thus it should be. It was then not impossible that, by some untoward action, or deed not well done, the blessed Paul, or any other of those similarly favoured, should after being joined unto God be capable of losing again the grace given to him, and being thrust back again to return to the humiliation whence he had arisen. For that which is wholly adventitious and from without may easily be spurned away, and is capable of being taken back even as it was given. Now then, my good sir: for my question is coming back to thee: if it is true, according to thy ignorant notions and most impious imagination, that even as Christ was speaking and working wonders in Paul, so one must admit that the Father is in the Son; what manner of doubt can there be that He must be in no sense whatever in His nature God, but rather something different from the Father indwelling in Him, the Father being God in very truth? For thus it was that Christ was in Paul. So then, [according to you,] the Only-begotten is a sort of instrument or implement [in the hand of the Father], cunningly devised to set forth His glory, in no wise differing from a flute or a lyre, giving utterance to whatsoever the mouth of the player might breathe into it or the touch of his finger call forth in rhythmic melody. And He will be acceptable to the Father as an assistance in the performance of His wonders, as one might conceive of a saw or an axe in the hands of a skilful carpenter. And then what can be more paradoxical than this? For if He is by nature as those heretics say, He must be altogether alien from God the Father; whereas in our opinion He is by nature God, and none other than God. But if the Son is severed from the essence of the Father, as far at least as pertains to His being in nature God, surely we are correct in inferring that the Son Who sits at the Father's right hand is placed in the same rank with the created world, and reckoned among the results of God's workmanship, and regarded in the light of a mechanical instrument, and looked upon henceforth as a servant to ourselves rather than as a master; or indeed that He is in strict truth not actually a Son at all. For never could one regard or accept in the light of a Son a being who was placed in the rank of a mere instrument. The Father, it would appear, has begotten an instrument to show forth His wisdom and skill, and is deemed to have generated something quite different from that which He is Himself. How could this possibly happen? Surely it is the height of folly to conceive such a notion. If therefore thou refusest to surrender that opinion concerning the Son which regards Him as an instrument or a servant, and if thou art unwilling to acknowledge Him as at all in truth a Son, and deniest His ineffable generation from the essence of God the Father; thou wilt be doing injustice to the glory even of the Father Himself: for then the Father will cease to be Father in veritable reality; for how could one who had not begotten a son of his own essence be at all in his nature a father? It would follow that the Holy Trinity is altogether falsely named, if neither the Father is truly Father, nor the Son in His nature Son. And the logical sequence to this view will be blasphemy against the Holy Ghost as well.

It would therefore follow in this case that we have been grossly deceived: our faith is a falsehood: the Holy Scripture is coining a lie when it calls God by the name of the Father. And if the Son is not in His nature God, as having been begotten of God the Father, we have been led astray, and together with us the citizens of the world above have erred also, even the undefiled multitude of the holy angels, when they joined us in glorifying and adoring the Son as One Who is in His nature God; being led on in some mysterious manner to sing the praise of one who (if we speak after the manner of the heretics' accursed folly) is a God-bearing vessel, the work of God's hands. And if the Father ever willed to withdraw from His relationship to the Son and His indwelling in Him, the Son would then be in no respect different from others who have fallen away from their original sovereignty, with nothing to distinguish Him, no trace within His nature of the Father Who begat Him; but rather one like ourselves in all things, who had only been strengthened by the Divine grace, and indeed honoured with the title of sonship, in the same degree as ourselves. Tell me then, why does He not Himself acknowledge His natural relationship to us? Why is it written: We perish for ever, whereas Thou abidest for ever? And why are we "servants" and He "Lord "? For even if we are called the sons of God, yet by acknowledging none the less our own proper nature we do not disgrace the honour done to us: but tell me the reason why----if He is like unto us and not at all superior to His creatures, inasmuch as He is not in nature God (for this is their ignorant opinion)----He does not confess His community with us in being a servant? Eather we find Him investing Himself with the honour and glory that peculiarly befit and are specially ascribed to the Divine nature, and saying to the holy disciples: Ye call Me Lord and Master, and ye say well; for so I am. This is the Saviour's saying: but our illustrious expositors, who introduce these doctrines attacking His Divinity, accept his words and affirmation asserting that He was truly called Lord, and yet thrust Him away from His natural lordship, because they are unwilling to confess Him as in His nature God of God; though they are not bold enough to bring against Him the worst of all the charges that their accursed blasphemy implies.

For that He wills not to be reckoned among those who hold the rank of servants, or even in the category of created objects, but rather that He ever looks to the freedom inherent in Himself by nature, even at the time when He was made in the form of a servant----all this thou wilt learn in the following manner. He had arrived at Capernaum, as we read in the Gospels: the collectors of the legal tribute-money came to Peter, and said: Doth not your Master pay the half-shekel? And when Christ heard of this, it is right that we should notice the question He addressed to Peter: The kings of the earth, from whom do they receive toll or tribute? from their sons or from strangers? And after Peter had wisely and sensibly acknowledged that it was a stranger to the kingdom, as regards birth and kinship as it is reckoned among us, who would be compelled to submit to ordinances and taxation; Christ forthwith brought forward His claim that a God-befitting nature was truly existent in Himself, by adding the words: Therefore the sons are free. Whereas if He had been a fellow-servant, and not a Son truly begotten of the essence of the Father, with no intimate natural relationship to the Father; why is it that, after implying that all besides are subject to the tribute, inasmuch as their nature is foreign to that of Him Who of right receives the tribute, and they are only in the rank of servants, He has claimed freedom for Himself alone? For it is by an inaccurate use of terms that attributes, which mainly and truly are befitting to the Godhead alone, are ascribed to us; whereas in Him they are in very truth inherent. And so if any one were to investigate accurately the nature of things created, he would perceive that to that nature the title as well as the fact of slavery most appropriately belongs; whereas if any like ourselves have been decorated with the glorious name of freedom, an honour that is due to God alone is attributed to them only by an inexact use of language.

Now here again is another question I should be very glad to ask them. Will they allow to Paul the epithet; of God-bearer, seeing that Christ dwells in him through the Holy Spirit, or will they be silly enough to deny this? For if they shall say that he is not in truth a God-bearer, this will be sufficient I think to persuade all men for the future to reject the nonsense they talk, and to hate them utterly, as men who shrink from saying no absurd thing. And if, avoiding this, they shall turn to the duty of saying the truth, and confess him to be truly a God-bearer, because that Christ dwells in him, will they not be convicted of very impiously saying that the Son is alien from the essence of God the Father? For Paul is no longer a God-bearer, if the Son is not in His nature God. But sometimes they blush, and say----for they are also characterised by recklessness and perverseness in argument----that the Son is truly God, yet not in His nature begotten of God. And there is no manner of doubt that any man whatever will exclaim against them on this point too; for how could one who is not in his nature begotten of God be God? Further, we add this. You say that the Son is in His nature God: how then could He Who is in His nature God be a God-bearer or a partaker of God? For no one could ever be a partaker of himself. For to what end will God dwell in God, as though in something different? For if the recipient is in nature just the same as the indweller may be conceived to be, what henceforth becomes of the need of the participation? And if in the same way that Christ dwelt in Paul, the Father also dwelt in Him, will not Christ be a God-bearer in the same way as Paul? And He will not in any other sense possess the quality of being in His nature God, through His having the need of a greater one, namely, the indwelling God. Then again this noble friend of ours goes further in his clever inventions, and by many proofs (as he seems to think them) he attempts to talk people round to his peculiar doctrine. For I think it is worth while to go through all his words in detail, and to make a direct investigation of the impious plot that he has laid, in order that he may be clearly convicted of numbering the Only-begotten among things created. And the wretched man, having buried his impiety towards Christ beneath a heap of cleverly devised conceits, confesses Him to be God, and yet, excluding Him from the Divinity that is truly and naturally His, imagines that he will elude the observation of those who are looking for the real truth.

Accordingly he writes thus: "But even as we, while we are said to be in Him, have our substance in no way mingled with His; in the same way also the Son, while He is in the Father, has His essence entirely different from the Uncreated One."

What lamentable audacity! What extravagant language, and how full of folly, or rather of all perversity and madness! Professing themselves to be wise they in reality became fools; and holding these views concerning the Only-begotten, they denied the Master that bought them, as it is written. For if they say that the Word of God is a man and one like ourselves, there remains nothing that prevents them from saying that He is in God in the same way that we are: but if they believe Him to be God, and have learnt to worship Him as being so by nature, why do they not rather ascribe to Him existence in a God-befitting way in His own Father, and also the possession of the Father in Himself? For this I think would be more fitting for those who are really lovers of God to think and say. And if we find them still cherishing their shamelessness undaunted, and persisting in the words they have uttered,----saying that the Father is in the Son in the same manner as may be the case with any one of us, who have been created out of nothing and formed out of the earth by Him,----why is it not permissible for those who wish to do so, to say henceforth with impunity: He that hath seen me hath seen the Father, and: I am in the Father, and the Father is in me? But I think that in this way any one would be condemned, and very properly, on a charge of the most utter folly possible. For not only is it absurd, but such a thing was never said by any of the saints in the inspired Scripture. On the other hand, they all concede to Him Who is in His nature Lord and God, the Only-begotten, an incomparable excellence above all good men; yea, verily, they proclaim aloud and say: Who among the sons of God shall be likened unto the Lord? How then is the Only-begotten any longer like us, if (according to the language of the saints) no one is His equal or His peer? Whereas if He is in God in just the same way that we are, we shall in consequence be compelled to say that the 3ompany of the saints are untruthful, and to ascribe to Him Who is in His nature Son nothing extraordinary which might distinguish Him as of a different rank from those who are sons only by adoption. Away with the loathsome idea, man! For we will not be so persuaded; God forbid! On the contrary, following the opinions of the holy fathers, we believe that we shall be well-pleasing unto God.

But seeing that they brought forward, as a proof of what they think and say, that well-known saying of Paul, that in God we live, and move, and have our being, arguing that when the Son is said to be in the Father the expression lacks precision, being adopted from our everyday life; come and let us subject their statement to the requisite investigation, and so convict them of deliberately misrepresenting the mind of the holy Apostle and most foolishly perverting to their own views what was said in absolute truth. For when the blessed Paul was at Athens and saw the inhabitants abjectly devoted to polytheistic error, although the people in that city were reputed wise, he attempted to lead them back from their ancient delusion, seeking (by argumentative exhortations to true piety) skilfully to convince them of the necessity for the future of knowing one God and one only, Who bestows on those that have been made by Him the power of moving and living and having their being. For the Creator of all, being in His nature Life, implants life in all, infusing into them by an ineffable process the power of His own Individuality. For in no other way was it possible that things which had received their allotted birth out of nothing should preserve their capability of existence: for surely each would have returned to its own nature, I mean back again to non-existence, unless, by the help of its relationship to the Self-Existent One, it had overcome the weakness of its own condition at birth. Therefore the inspired Paul very rightly and properly said, by way of showing that God is the life of the universe, that in Him we live, and move, and have our being: not at all meaning what the heretics invented for themselves, in corrupting (to suit their own peculiar theories) the true signification of the Holy Scriptures; but rather saying exactly what was true, and also highly profitable for those who were just being trained up to a knowledge of God. And, if it is needful to put it even more plainly, he has never wished to imply that we, who are in our nature men, are yet contained in the essence of the Father, and appear as existing in Him; but rather that we live and move and have our being in God, that is, our life consists in Him.

For notice that Paul did not say simply and unreservedly, "We are in God," and nothing more. This was on account of thy ignorance, my good friend, and most naturally so. But he employed different expressions, by way of interpreting the exact meaning of his words. After beginning with the statement: "We live," he added thereto the further idea: "We move" and thirdly he brought in the phrase: "We have our being;" presenting this also, so as to supplement the meaning of the previous words. And I think that the correct argument we shall use concerning this matter will very probably put to shame the ungodly heretic: but if he insists in his opposition, and drags round the words "in God" to the meaning which pleases himself and no one else, we will set |280 forth the common use of the inspired Scripture. Scripture is wont occasionally to use the words "in God" in the sense of "by God." For let that man tell us what is the meaning of a certain Psalmist's declaration, when he says: "In God" let us do valiantly; and again, addressing God: "In Thee" will we push down our enemies. For surely no one will suppose that the Psalmist means this, that he promises to accomplish something valiantly "in the essence of God," nor even that "in that essence" we shall discover our own enemies and push them down: but he uses the words "in God" in the sense of"by [the help of] God," and again, "in Thee" in the sense of "by Thee." And why also did the blessed Paul say in his letter to the Corinthians: I thank my God concerning you all for the grace which was given you "in Christ Jesus," and again: But of Him are ye "in Christ Jesus," Who was made unto us wisdom from God, and righteousness, and sanctification, and redemption? For will any one reasonably maintain that the Spirit-bearer says that the grace which was bestowed on the Corinthians from above was given "in the actual essence of Christ," or to quote the authority of Paul in support of heterodoxy? Surely such a one would be evidently talking nonsense. Why therefore, setting aside the ordinary usage of terms in the Sacred Scriptures, and misrepresenting the intention of the blessed Paul, dost thou say that we are "in God," that is, "in the essence of the Father," because thou hearest him say to those in Athens, that in Him we live, and move, and have our being?

"Yes," says the defender of the pernicious opinions, "but if it seems to thee right and proper that the words 'in God' should bear and be acknowledged to bear the sense of ' by God,' why dost thou make so much needless ado? And why dost thou bring against us charges of blasphemy when we maintain that the Son was made ' by the Father'? For behold, He Himself says: I am 'in the Father,' in the sense of 'by the Father,' at least according to thy explanation, Sir, and |281 according to the common usage, which thou hast just laid before us in thy quotations from the Sacred Scriptures."

But I say that it is necessary to defend myself again in reply to this, and lay bare their mischievous intentions and pernicious notions. For I am astonished that, after hearing gladly that it is a usage of the Sacred Scripture to use the words "in God" as equivalent to "by God," and after approving and accepting the phrase merely for the sake of being able to say something against the glory of the Only-begotten, they have by no means become conscious of the fact that they will again be convicted of talking as foolishly as before, although they claim to be wise and acute. For if our opponents were the only ones entrusted with the duty of defending from time to time the usage of the inspired Scripture in reference to the essence of the Only-begotten, and of saying that He was made by the Father, because of this, that He says He is "in God," and we have allowed that "in God" is to be understood in the sense of "by God;" then it might have seemed at least probable that their mischievous intention rested on grounds not altogether unreasonable. But if in truth there is nothing which can prevent us also, in our eagerness to refute by a reductio ad absurdum the unsoundness of the sentiments they hold, from carrying on the force of the meaning implied so as to make it refer to the Father Himself, and from saying plainly that since Christ also adds this: The Father is "in Me," we must understand it in the sense of "by Me," so that as a consequence the Father Himself also will be a creature; surely then they, having relied on arguments so very foolish, will be universally condemned as guilty of unmitigated folly. For just as the Son says that He Himself is "in" the Father, so also He said that the Father, is "in" Him: and if they wish the words "in the Father" to be understood in the sense of "by the Father," what is there that prevents us from saying that the words "in the Son" shall be understood in the sense of "by the Son "? But we will not suffer ourselves again to be drawn down with them into such an abyss of folly. For neither will we say that the Son is made by the Father, nor indeed that He from Whom are all things, namely God the Father, was brought into existence by the Son; but rather, referring the usage of the inspired Scripture in due proportion to each occasion or person or circumstance, we shall thus weave together our theory so as to make it on all essential points faultless and indisputable. For with regard to those who out of nothing have been created into being, and have been brought into existence by God, surely it would be most fitting that we should regard them and speak of them as being "in God" in the sense of "by God:" but with regard to Him Who is in His nature Son and Lord, and God and Creator of the universe, this signification could not be specially or truly suitable. The real truth is that He is naturally in the Father, and in Him from the beginning, and has Him in Himself, by reason of His showing Himself to possess identity of essence, and because He is subject to no power that can sever between Them, and divide Them into a diversity of nature.

And perhaps it might seem to minds more open to conviction that this matter has been sufficiently discussed, as indeed I think myself: yet our opponent will by no means assent to this; but he will meet us again with the objection, dishing up again the argument introduced by him at the first, that the Father is in the Son in the same manner, as we are in Him.

"What then," we might say, judiciously rebuking the unsoundness and childishness of his thoughts and words, "dost thou say that the Son is in the Father even as we are in Him? Be it so. What limit to our natural capacity then," we shall reply, "is there, that prevents us from using expressions with respect to ourselves as exalted as any of those which Christ is seen to have used? For He Himself, seeing that He is in the Father and has the Father in Himself, inasmuch as He is thereby both an Exact Likeness and Very Image of Him, uses the expressions: He that hath seen Me hath seen the Father: I and the Father are One. But with regard to ourselves, tell me, if we are in Him and if we have Him in ourselves exactly in the same way that Christ Himself is in the Father and the Father in Him, why do we not extend our necks as much as we can, and, holding our heads high above those around us, say with boldness: "I am in Christ and Christ in me: He that hath seen me hath seen Christ: I and Christ are one "? Then what would come next? No one, I think, would any longer have any just cause for alarm, or any sufficient ground for hesitation, to prevent his speaking as follows, daring henceforth to say concerning the Father Himself: "I and the Father are one." For if the Father is one with the Son, surely such a man, having become an exact image of the Exact Image, namely of the Son, will share henceforth in all the Son's relations to the Father Himself. Who therefore will ever descend to such a depth of madness as to dare to say: "He who hath seen me hath seen Christ: I and Christ are one"? For if thou attributest to the Son the being in the Father and the having the Father in Himself in some non-essential manner and not in His nature, and supposest that we in like manner are in Christ and Christ in us; in the first place the Son will be on the same footing as ourselves, and in the next place there is nothing that prevents us at our pleasure from passing by the Son Himself as though He were an obstacle in our way, and rushing straight on to the Father Himself, and claiming that we are so exactly assimilated to Him that nothing can be found which distinguishes us from Him. For the being said to be one with anything would naturally bear this meaning. Do ye not then see into what a depth of folly and at the same time of impiety their minds have sunk, and of what absurd arguments the wild attack upon us has consisted? What their excuse is therefore for saying and upholding such things, and for buoying themselves up on such rotten arguments, I will now again tell. Their one endeavour is to show that the Son is altogether alien and altogether foreign to the essence of the Father. For we shall know that we are speaking the truth in saying this, by reference to the words that follow after and are closely connected with the heretic's previous blasphemies. For he proceeds thus: "But even as we, while we are in Him, have our substance in no way mingled with His; in the same way also the Son, while He is in the Father, has His essence entirely different from the Unbegotten God." What sayest thou, O infatuated one? Hast thou made thy blasphemy against the Son in such plain language? Will any one therefore venture to say that we are trying to heap upon the heads of the God-opposers groundless and false accusations'? For see clearly, they attribute to Him no superiority whatever over those who have been made of earth and have been by Him brought into existence. And although I can scarcely endure the things which the wretched men have dared to say, I will endeavour to prove this, as being in accordance with the scope of Divine Scripture, namely, that since they deny the Son they deny at the same time the Father also, and thenceforth are without God and without hope in this world, as it is written. And to prove that we are right in saying this, the God-beloved John will come forward as a trustworthy witness on our side, for he wrote thus: He that denieth the Father and the Son. Whosoever denieth the Son, the same hath not the Father; he that confesseth the Son hath the Father also. And surely the Spirit-bearer speaketh very rightly, not failing to make his statement conform fittingly to his argument. For because he knows that [God the Father] is essentially in His nature what He is said to be, namely a Father, and that not merely in name but rather in reality, he consequently says that the One is necessarily denied when the Other is denied. For concurrently in some way or other with One Who is really in His nature a Father and is so conceived of, there must always be the knowledge and manifestation of the Offspring that proceedeth from Him; and One Who has been in very truth begotten involves the Personal existence of Another capable by nature of begetting. For no sooner do we recognise a man as a father than we understand him to have begotten offspring, and we can by no means consider the idea of an offspring without implying that some father has begotten it. Thus by either term the other conception is produced in the minds of those who hear it, and so any one who denies that God is truly a Father makes out the generation of the Son to be altogether impossible, and similarly any one who does not confess the Son to be an Offspring must by implication lose all knowledge of the Father. When therefore, as from a sling, he hurls at us his unholy arguments, and maintains that the Son has His essence quite distinct from that of the Unbegotten God, why does He not openly deny that the Son is really a Son? And if there is not a Son, the Father Himself can no longer be conceived of as truly a Father. For whose Father will He be, if He has not begotten any Offspring? What we say is, that the Son is quite distinct from the Person, but not from the essence, of the Father; not being alien from Him in His nature, as forsooth these God-opposers think, but being possessed of His own Person and His own distinct subsistence, inasmuch as He is Son and not Father. But, if we understand our own mind rightly, we would not ourselves say, nor would we assent to any of the brethren who say, that He is distinct from the Father in regard to essence. For how can distinction exist in that one thing, with reference to which each individual has some special characteristic? For Peter is Peter, and not Paul, and Paul is not Peter; yet they remain without distinction in their nature. For both possess one kind of nature, and the individuals who are associated in a uniformity of nature have that same kind without any difference at all. |286

For what reason are we saying such things as this? We confess that our object is to show that those who hold such blasphemous opinions rob the Son of the Godhead which is His by nature, when they (as we have already explained) ascribe to Him nothing more than a non-essential relationship to God the Father. Else why do they put forward ourselves in illustration of their argument, and say: "Even as we have our substance in no way mingled with His, while we are in Him; so also He Himself has His essence entirely different from God, although He is said to be in Him "? Is not their craftiness patent to all men? Will not any one be right in saying that the man who vomited forth such an abominable statement as this must surely be one of the "mockers" announced beforehand by the Spirit? For what does Jude, the disciple of the Saviour, write to us in his epistle? But ye, beloved, remember ye the words which have been spoken before by the apostles of our Lord Jesus Christ; how that they said to you, that in the last time there shall come mockers, walking after their own ungodly lusts. These are they who make separations, sensual, having not the Spirit. For no man whatsoever, who speaks in the Holy Spirit, will say anything against the glory of the Only-begotten. For I maintain that this is just the same as saying: Jesus is anathema. On the other hand, sensual and worthless men, and those whose hearts are devoid of the Holy Spirit, make separations between the Father and the Son; asserting that the latter is as essentially and completely severed from the former as are created things and each of the works made by Him, and believing Him to be in the Father only in the same way that we are in Him.

And that they who have dared to write such things have thereby reached the furthest verge of folly, let us if you please proceed to show in another way, as is quite possible, from the Divine Scripture; and let us hasten to prove to our hearers that we are in the Son in one way, whereas the Son is in His own Father in another way. For one person is not a likeness of another's substance when he conforms himself to that other by the exercise of a virtuous will, nor is he on that account said to be in the other; but when he is in natural identity with the other, and possesses one essence with him. And let the most wise John be called in as a witness for us on this point, since he says: Yea, and our fellowship is with the Father and with His Son Jesus Christ. How then, pray, do they say, and in what manner do they think fit to assert, that we have fellowship with the Father and with His Son Jesus Christ? For if we are considered to be in Them, as having our own essence commingled with the Divine nature, that is, with the Father and the Son, and if the expression "fellowship" does not rather refer to the similarity of our wills; how can we have it with the Father and with the Son, when (according to these heretics) the Father and the Son are not Consubstantial? For in that case we must hold opinions worthy of ridicule, and say that we have cleft our own nature asunder into two parts, and given one half to the Father and the other to ourselves and to the Son, and thus we consider ourselves to be in Them. Or else we must reject such absurdity of statement, and say that by doing our best to make our own disposition brightly radiant through the exercise of a virtuous will and through conformity to the Divine and ineffable beauty, we obtain for ourselves the grace of fellowship with Them. But shall we therefore say that the Son is in the Father after a similar manner to this, and that He only possesses a non-essential and artificially-added fellowship with the One Who begat Him? And yet, if so, why in the world does He wish, through the similarity and indeed identity of their works, to lead our mind to feel the necessity of believing without any hesitation that He is Himself in the Father, and that He again has also the Father in Himself? For is it not seen by every one to be perfectly evident and true that, wishing the brilliancy of His deeds to be investigated by us, He shows Himself equal in strength to |288 His own Father, as if the severance as regards essence and the difference as to nature no longer maintained their position; since both Himself and the Father glorify themselves by similar achievements"?

For observe how we who constantly strive after conformity with God do (so to say) render ourselves worthy of fellowship with Him, not in such ways as these, but in certain other ways. For when we show pity to one another, are ardently devoted to works of love, and practise all that is truly respectable in our ordinary life, even then we can hardly venture to pronounce ourselves "in God." And John is our witness, saying: Hereby know we that we are in Him: he that saith he abideth in Him ought himself also to walk even as He walked; and again: As for you, he says, let that abide in you which ye heard from the beginning. For if that which ye heard from the beginning abide in you, ye also shall abide in the Son, and in the Father. And what he means by "that which ye heard from the beginning," which he bids to remain in us in order that we may be in God, he himself will make no less clear to us when he says: For this is the command which ye heard from the beginning, that ye should love one another. Thou hearest how we are in God, namely, by practising love one towards another, and striving to the utmost of our power to walk in the footsteps of our Saviour, imitating His virtue. When I say virtue, I do not mean such as was shown by Him in being able to create heaven, and make angels, and set fast the earth, and spread out the sea; nor that which He exhibited when, in His ineffable and simple majesty, by a word He lulled the violence of the winds, and raised up the dead, and graciously bestowed sight on the blind, and with great authority bade the leper be cleansed: but rather that virtue which may be suitable to the capacities of our humanity. We shall find Him, as indeed Paul says, reviled by the unholy Jews, yet not reviling again; instead of that, we see Him suffering, yet not threatening, but rather committing Himself to Him that judgeth righteously. Again, we shall find Him saying: Learn of Me; for I am meek and lowly in heart; and ye shall find rest unto your souls.

So then, when we strive by such conduct as this to imitate Christ Who is our guide unto all virtue, we are said to abide both in the Father and in Him, obtaining this distinction as a reward and compensation for the worthiness of our life. But the Son does not wish us to estimate in this way the brilliance that is inherent in Him: He bids us direct our natural shrewdness of attention to the magnificence of His miracles, and infer from thence the exact resemblance which He has to His own Father; so that henceforth we may believe that, as they are Consubstantial, it is thus that He has in Himself the One Who begat Him, and that He Himself is also in the Father. Or let our opponents come forward and teach, that when the Son is conceived of as being in the Father, He too in common with ourselves has this distinction as a reward, and as a fair payment for conducting His life according to the law of the Gospel. But I suppose that even this appears to them nothing dreadful: for to men by whom no form of talking is unpractised, what expression, however extravagant and monstrous, seems unfit for use? It is possible therefore that they will say even this, that the Son is in the Father and again has also the Father in Himself on this account, namely, because He fashions Himself like to the Father by practising the virtues that are also attainable by us. And we would reply, "Why then, honoured Sirs, when Philip said: Lord, show us the Father, did not the Christ put forward all the holy Apostles as a likeness and accurate representation of Him Whom they meant, and say, 'Have we [all] been so long time with one another, and dost thou not know the Father?" Whereas He does not associate with Himself a single one of the others, but comparing Himself alone to the Father alone, He passes over our attributes as small matters altogether; and not willing that the Divine essence should be thought accurately imaged in human attributes, He has reserved to Himself alone the perfection of resemblance. For He says: He that hath seen Me hath seen the Father. Then to these words He straightway added: Believe that I am in the Father and the Father is in Me. For seeing that He possesses resemblance in the most absolute exactness, He must as a necessary consequence possess in Himself the Father, and be possessed (so to speak) by the Father. For think of something of the same kind, and accept it as an illustration of the words we are considering. If, for instance, any one were by chance to bring into our presence the son of Abraham or of any other man, and then were to question him as to the nature of his parent, desiring to learn precisely who and what kind of person the parent was; would not the youth employ reasonable language if he were to point to his own nature and say, "He that hath seen me hath seen my father: I am in my father, and my father is in me?" Then as a proof of his speaking the truth, would it not be fitting that he should draw attention to the identity with his father exhibited in his human doings and his physical peculiarities, and say: "Believe me for the very works' sake, seeing that I have all the qualities and can perform all the actions which pertain to human nature?" Indeed I think every one will say and will justly allow, both that he speaks the truth and that (in alleging the identity) he puts forward an accurate indication of the relationship involved in their particular actions. Why then do not they, who pervert such things as are right, persuade their own disciples to travel on the straight path of reasoning, instead of thrusting them off from the well-trodden king's highway, and taking an untrodden and rugged route, both deceiving themselves and destroying those who feel it their duty to follow them? We, however, not taking their road, will keep along the direct path; and, giving credit to the Sacred Scriptures, we believe that the Son, Who is in His nature begotten of God the Father, is of equal strength and Consubstantial with the Father, and essentially His Image; and therefore that He is in the Father, and the Father in Him.
[AD 444] Cyril of Alexandria on John 14:11
Believe that I am in the Father, and the Father is in Me

CHAPTER I. That by reason of the identity of Their nature, the Son is in the Father, and the Father again is in the Son.

He now admits plainly, or rather enjoins on the disciples henceforth, that it is fitting that we should be no otherwise minded than as the Word of Truth Himself may desire. For He is Consubstantial with His Father, nothing whatever intervening or in any way separating One from the Other into a diversity of nature. He is One with Him, so that the Son's nature appears in the essence of the Father, and in the essence of the Offspring appears conspicuously that of God the Father; just as one might see happen in the case of human relations. For we are in no way different in our nature from our offspring, nor are we sundered from them in an alienation of nature, although we are distinguished by a difference of outward personality; in illustration of which, let any man who has looked upon the son begotten by himself consider the history of the blessed Abraham. But in the case of men the difference is often very considerable, each one tending definitely, in a way, towards a retirement and withdrawal of himself into a peculiar line of life and manners, without feeling personally bound up in the other; although their unity of essence may be certain and evident to all. But in the case of God, Who is ever in perfect accordance with His nature, thou wilt believe it to be otherwise. The Father indeed is in individual personality Father and not Son; and again similarly He Who cometh forth from the Father is Son and not Father; and the Spirit is peculiarly Spirit. But since the Holy Trinity is united and joined together into a oneness of Godhead, there is among us One God alone: and it would be impossible to attribute to each one of the Persons here indicated the habit of secession from the others, and neither will ever withdraw into absolute separation; but we believe that each Person is in very substance exactly what we have here entitled Him. We consider that the Son, being of the Father, that is, of His essence, proceeded forth from Him in a manner ineffable, and yet abides in Him. Likewise also concerning the Holy Spirit: He proceeds in very truth from God as He is by nature, and yet is in no wise severed from His essence; but rather proceeds forth from Him, still abiding ever in Him, and is supplied to the saints through Christ; for all things come through the Son by the Holy Spirit. Such is the true and upright teaching that the wisdom of the holy fathers has taught us: thus we have been trained also by the Holy Scriptures themselves to speak and to think. And the Lord would cheer us onward to accept this unreviled faith, when he says: Believe that I am in the Father, and the Father in Me.
[AD 444] Cyril of Alexandria on John 14:11
In these words Christ distinctly says that he could never have worked and accomplished those miracles that are unique to the divine nature if he, himself, had not been essentially of the same divine nature.… [Only heretics] whose hearts are devoid of the Holy Spirit make separations between the Father and the Son and assert that the Son is essentially and completely severed from the Father in the way that created things and divine works are separate from God the Father.

This refers to the other miracles that the apostles did, such as healing a man through their shadow falling on him. But this incident did not reveal the fullness of this saying, but rather it was fulfilled in the fact that, when he used the power of the Godhead for an act of kindness, the disciples on the one hand worked through the power given to them for the service of those who believe and the punishment of the extremely wicked, and on the other hand they exceeded the power of their teacher, even though he was mightier in his ability to punish the godless, since he chose to restrain and control his power to punish in the meantime until the right moment of judgment.

And so he promised that he himself would also do those greater works. Do not let the servant exalt himself above his Lord or the disciple above his Master. He says that they will do greater works than he does himself, but it is all by his doing such works in or by them, and not as if they did them of themselves. And so we have the song that is addressed to him, “I will love you, O Lord, my strength.” But what, then, are those greater works? Was it that their very shadow, as they themselves passed by, that healed the sick? For it is a mightier thing for a shadow, than for the hem of a garment, to possess the power of healing. The one work was done by Christ himself, the other by them. And yet it was he that did both.

But there is still something to excite thought in his doing such greater works by the apostles. For he did not say, as if merely with reference to them, “the works that I do shall you do also. And greater works than these shall you do,” but wishing to be understood as speaking of all that belonged to his family, he said, “He who believes in me, the works that I do shall he do also. And greater works than these shall he do.” If, then, he who believes shall do such works, he who shall not do them is certainly no believer, just as “He who loves me, keeps my commandments” implies, of course, that whoever does not keep them does not love.… In a similar way, also, it is said here, “He who believes in me shall do such works.” The one who does not do good works, therefore, is no believer. What have we here, then, brothers? Is it that one is not to be counted among believers in Christ who will not do greater works than Christ? It would be hard, unreasonable, intolerable to suppose so, that is, unless it is rightly understood. Let us listen, then, to the apostle when he says, “To him who believes in him who justifies the ungodly, his faith is counted for righteousness.” This is the work in which we may be doing the works of Christ, for even our very believing in Christ is the work of Christ.

[AD 430] Augustine of Hippo on John 14:12-14
(Tr. lxxi. 3) But what are these greater works? Is it that the shadow of the Apostles, as they passed, by, healed the sick? It is indeed a greater thing that a shadow should heal, than that the border of a garment should. Nevertheless, by works here our Lord refers to His words. For when He says, My Father that dwelleth in Me, He doeth the works, what are these works but the words which He spoke? And the fruit of those words was their faith. But these were but few converts in comparison with what those disciples made afterwards by their preaching: they converted the Gentiles to the faith. Did not the rich man go away sorrowful from His words? And yet that which one did not do at His own exhortation, many did afterwards when He preached through the disciples. He did greater works when preached by the believing, than when speaking to men's ears. (lxxii. 2). Still these greater works He did by His Apostles, whereas He includes others besides them, when He says, He that believeth on Me. Are we not to compute any one among the believers in Christ, who does not do greater works than Christ? This sounds harsh if not explained. The Apostle says, To him that believeth on Him that justifieth the ungodly, his faith is counted for righteousness. (Rom. 4:5) By this work then we shall do the works of Christ, the very believing in Christ being the work of Christ, for He worketh this in us, though not without us. Attend then'; He that believeth on Me, the works that I do, shall he do also. First I do them, then he will do them: I do them, that he may do them. Do what works but this, viz. that a man, from being a sinner, become just? which thing Christ worketh in us, though not without us. This in truth I call a greater work to do, than to create the heaven and the earth; for heaven and earth shall pass away, but the salvation and justification of the predestinated shall remain. (c. 3.). However, the Angels in heaven are the work of Christ; shall he who worketh with Christ for his own justification, do greater even than these? Judge any one which be the greater work, to create the just, or to justify the ungodly? At least, if both be of equal power, the latter hath more of mercy. But it is not necessary to understand all the works of Christ, when He says, greater works than these shall he do. These perhaps refers to the works He had done that hour. He had then been instructing them in the faith1. And surely it is a less work to preach righteousness, which He did without us, than to justify the ungodly, which He so does in us, as that we do it ourselves. Great things truly did our Lord promise His people, when He went to His Father: Because I go unto My Father.

(Tract. lxxiii. 2) And that no one might attribute the merit to himself, He shows, that even those greater works were His own doing: And whatsoever ye shall ask in My name, that will I do. Before it was, He shall do, now, I will do: as if He said, Let not this appear impossible to you. He that believeth in Me, will not be greater than I; but I shall do greater works then than now; greater by him that believeth on Me, than now by Myself; which will not be a failing, but a condescension.

(Tract. lxxii. 2) Whatsoever ye shall ask. Then why do we often see believers asking, and not receiving? Perhaps it is that they ask amiss. When a man would make a bad use of what he asks for, God in His mercy does not grant him it. Still if God even in kindness often refuses the requests of believers, how are we to understand, Whatsoever ye shall ask in My name, I will do? Was this said to the Apostles only? No. He says above, He that believeth on Me, the works that I do shall he do also. And if we go to the lives of the Apostles themselves, we shall find that he who laboured more than they all, prayed that the messenger of Satan might depart from him, but was not granted his request. But attend: does not our Lord lay down a certain condition? In My name, which is Christ Jesus. Christ signifies King, Jesus, Saviour. Therefore whatever we ask for that would hinder our salvation, we do not ask in our Saviour's name: and yet He is our Saviour, not only when He does what we ask, but also when He does not. When He sees us ask any thing to the disadvantage of our salvation, He shows Himself our Saviour by not doing it. The physician knows whether what the sick man asks for is to the advantage or disadvantage of his health; and does not allow what would be to his hurt, though the sick man himself desires it; but looks to his final cure. And some things we may even ask in His name, and He will not grant them us at the time, though He will some time. What we ask for is deferred, not denied. He adds, that the Father may be glorified in the Son. The Son does not do any thing without the Father, inasmuch as He does it in order that the Father may be glorified in Him.

[AD 444] Cyril of Alexandria on John 14:12
If anyone should think to discourse hereon commensurately with the extent of the meaning of what is here submitted to us. the task would be broad and deep. But if we consider what is rather profitable for the hearers, we shall think it beseems us to grasp in general wise the things signified, and to curtail the length of our discourse. For so would the meaning be most easy to be received by most men. So then, wishing to show forth that He was Consubstantial with His own Father, and that He is a Very Image of Him; carried in the Father as in an Archetype, albeit having the Archetype in Himself, as being a Very Image both naturally and essentially, and not in virtue of any shaping which implies a process of moulding and fashioning; for the Divinity transcends shape, inasmuch as. it is incorporeal withal: I, He says, am in the Father and the Father is in Me. But to the end that we may not look for the identity of the resemblance and the exact conformity thereof in any other sort than as a conclusion from those prerogatives alone that attach to His nature; for it was possible therefrom to see that the similarity is essential and natural; He says: Or else, believe by reason of the works. For indeed He very rightly thought that of a surety if any man beheld Him radiant with the like mighty works to those of God the Father, He would accept Him for a really natural Image and Likeness of His essence; for nought save what is naturally of God would ever do equivalent deeds to those of God; nay, neither could the power to work wonders on any wise in equal measure with the Divine nature come to belong to any created thing. For utterly unapproachable and beyond reach to them that have been called into being out of nothing are the proper excellences of the Eternal. And in no wise was it likely that any would doubt that the Saviour's saying would be utterly irreproachable, at least in the eyes of the right-minded; yet, as God, He was not ignorant that even what was well said would be, to them that held opposite opinions, an occasion and a pretext for strange teaching. With intent then that no place for loquacity might be left herein for them that pervert such things as are right, and lest they should say it was not of His immanent might nor of His own power that the Son became a worker of wonders, but only inasmuch as He had within Him the Father doing the works: on this account, as He Himself said and insisted, the Lord (when need arose) courted them with words that might allure their minds: for He promises herein that He will be to them that believe on Him a Supplier of what things soever they will ask, and promises that He will supply to them not merely an equal power and authority but the same with increase: for greater things, He says, than I have done, shall he do. Seest thou then how He cuts short, and profitably so, the boldness of our opponents, and by His refutations of error reins in men (as it were) when they are rushing over precipices? For anyone will say to them: "O fools and blind, whereas ye suppose the Son to have been able to effect nothing of Himself, but rather to have been supplied by the Father with the power and authority for all those things that have been wondrously accomplished; how does He promise that He will grant to them that believe on Him to effect even greater things? How shall another, by borrowing the power from Him, effect what He has not done Himself? For notice that He has not said herein that the Father will supply power to them that believe; but, Whatsoever ye shall ask in My Name, I will do it. But He Who as God imparts to others the power to effect even those greater things, how could He have been Himself supplied with the power by another?" So that what they say is utter nonsense, and thoughtless trash, and inventions of a devilish perversity. But no man would contemplate the power of the Son as in any wise limited, nor as extending to one thing but insufficient to reach things still greater; nay, but as doing easily whatsoever it will, and bestowing on the worthy the power to glory in thrones, it may be of equal honour, or it may be even more highly exalted. And let none suppose us to say that any of those who have set store by their faith in Him will ever have such excess of power as to be able to fashion a heaven, or to make a sun and a moon, or the brilliant choir of the stars, or peradventure to create angels, or an earth, or such things as are therein. For the aim of His words is not directed towards these things, but is bent upon the things whereon it was reasonable that so it should be; and He overpasses not the measure of the splendour that beseems mankind, in glory to wit, and holiness. For surely it is for this cause, by way of restraining His words from ranging as it were whithersoever a man might desire, and of confining Himself to those wondrous works which He did while on earth after He became man, when He draws the contrast with the greatness of the still greater deeds, that He says: "He shall do the things which I have done, and greater things than these." For it was not because He was too weak to accomplish the greater things, that He held back His own power within the bounds of the things which He accomplished; but when He has done what was needful, and all perchance for which opportunity offered, He kindly gives us to understand by these words, that the reach of the incomprehensible greatness of His immanent power is not limited to those things. But to the end that, preserving the order of the thoughts presented to us, we may set the minds of our hearers on the contemplation of His utterance, [we will repeat that] He says: Verily, I say unto you, he that believeth on Me, the works that I do shall he do also; and greater works than these shall he do; because I go unto the Father.

Then, "What is this?" one of the hearers might say with some reason, "I mean the Son's going to the Father in order that they who believe on Him may be able to effect things even still greater than the deeds exhibited by Himself? Surely the saying introduces some hidden subject for contemplation." To learn what it is that He says, consider Him as perhaps meaning: ----"O ministers and genuine pupils of My words, so long as I abode with you on the earth, and had My conversation as a man, I did not exhibit the power of the Godhead undimmed before you: I both spake and acted as befitted the measure of My humiliation and the condition of a slave. But thereafter, when those things shall have been be-seemingly accomplished, then also will the mystery of the dispensation in the flesh be completed for Me. For almost immediately I shall suffer death and shall rise to life again. And I promise to then bestow on you the power to accomplish works still greater than My own miracles. And the time for this is even now at hand, and so is the glory of their accomplishment. For I am going to the Father, that is, to sit down with Him and to reign with Him as God of God in unveiled power and authority, [and in the fulness] of My own nature to give good things unto My friends. Whatsoever ye shall ask," He says, "in My Name, I will do it, when the time has been completed wherein it was necessary," He says, "that I should show Myself in the garb of humiliation. I have observed all that was requisite to the proper carrying out of the scheme of the Incarnation; and now henceforth I promise that unveiledly as God I will work the works of God, not thrusting out the Father from the glory so God-befitting, but with intent that He may be glorified in the Son." For if the Offspring is glorified, the Parent also shall assuredly be glorified in Him. For the Son, being ever in His nature God, would have been declared by many other signs; yet no less also is He disclosed by receiving the prayers of the saints, and granting them whatsoever they might ask and wish. How then should not the Father be glorified in Him? For like as He would have been grievously blamed, and naturally so, if the Offspring that came forth from Him had not been in His nature God; in like manner He will be exceeding glorious in that He has for the Fruit that came forth from His essence One Who is God and can skill so well to do all things and to enable others to do them.

But if it tends to the glory of the Father that the Son should be seen possessed of God-befitting prerogatives, what manner of punishment shall fasten upon the heretic, forasmuch as he dreads not to disparage Him with shameless blasphemies in divers manners? And I will further say another thing, in no small measure (as I deem) at issue with their crude ignorances. For if we pray to the Son and seek our petitions from Him, and He pledges His promise to grant them; how could it be that He is not by nature God, and begotten of One Who is in His nature God? For if they conceive Him not so to be, and say that He was created, how shall we any longer be distinguished from those who invoke the sun, or the heaven, or any other of the creatures? For if, exceeding mischievously, ashamed of the ungainliness of their own folly, they say that albeit a creature equally with the rest of the creatures yet He hath a certain incomparable supereminence over all; notwithstanding let them be assured that none the less will they outrage the glory of the Father, that is, the Son, so long as ever they say that He is one in the number of the things that have been made. For the issue is, not whether He is haply a great or a small creature, but whether He is a creature at all, and is not rather in His nature God; which indeed is the truth.
[AD 1107] Theophylact of Ohrid on John 14:12-14
This is an explanation of the doctrine of miracles. It is by prayer, and invocation of His name, that a man is able to work miracles.

Observe the order (ἀκολουθίαν) in which the glorifying of the Father comes. In the name of Jesus miracles were done, by which men were made to believe the Apostles' preaching. This brought them to the knowledge of the Father, and thus the Father was glorified in the Son.

But if we think it impious to believe that the Father has handed over all judgment to the Son in such a way that he does not have it himself—for he has it and cannot lose what the divine majesty has by its very nature—we ought to consider it equally impious to suppose that the Son cannot give what either men and women can merit or any creature can receive, especially as he himself has said, “I go to my Father, and whatever you shall ask of him in my name, that will I do.” For if the Son cannot give what the Father can give, the Truth has lied and cannot do what the Father has been asked for in his name. He therefore did not say, “For whom it has been prepared by my Father,” in order that requests should be made only of the Father. For all things that are asked of the Father, [the Son] has declared that he [himself] will give. And finally, he did not say, “Whatever you shall ask of me, that will I do” but “Whatever you shall ask of him in my name, that will I do.”

Do you see His authority? The things done by means of others Himself does; has He no power for the things done by Himself, except as being wrought in by the Father? And who could say this? But why does He put it second? To confirm His own words, and to show that the former sayings were of condescension. But the, I go to the Father, is this: I shall not perish, but remain in My own proper Dignity, and Am in Heaven. All this He said, comforting them. For since it was likely that they, not yet understanding His discourses concerning the Resurrection, would imagine something dismal, He in other discourses promises that He will give them such things, soothing them in every way, and showing that He abides continually; and not only abides, but that He will even show forth greater power.

3. Let us then follow Him, and take up the Cross. For though persecution be not present, yet the season for another kind of death is with us. Mortify, it says, your members which are upon earth. Colossians 3:5 Let us then quench concupiscence, slay anger, abolish envy. This is a living sacrifice. Romans 12:1 This sacrifice ends not in ashes, is not dispersed in smoke, wants neither wood, nor fire, nor knife. For it has both fire and a knife, even the Holy Spirit. Using this knife, circumcise the superfluous and alien portion of your heart; open the closedness of your ears, for vices and evil desires are wont to stop the way against the entrance of the word. The desire of money, when it is set before one, permits not to hear the word concerning almsgiving; and malice when it is present raises a wall against the teaching concerning love; and some other malady falling on in its turn, makes the soul yet more dull to all things. Let us then do away these wicked desires; it is enough to have willed, and all are quenched. For let us not, I entreat, look to this, that the love of wealth is a tyrannical thing, but that the tyranny is that of our own slackmindedness. Many indeed say that they do not even know what money is. For this desire is not a natural one; such as are natural were implanted in us from the first, from the beginning, but as for gold and silver, for a long time not even what it is was known. Whence then grew this desire? From vainglory and extreme slackmindedness. For of desires some are necessary, some natural, some neither the one nor the other. For example, those which if not gratified destroy the creature are both natural and necessary, as the desire of meat and drink and sleep; carnal desire is natural indeed but not necessary, for many have got the better of it, and have not died. But the desire of wealth is neither natural nor necessary, but superfluous; and if we choose we need not admit its beginning. At any rate, Christ speaking of virginity says, He that is able to receive it, let him receive it. Matthew 19:12  But concerning riches not so, but how? Except a man forsake all that he has, he is not worthy of Me. Luke 14:33 What was easy He recommended, but what goes beyond the many He leaves to choice. Why then do we deprive ourselves of all excuse? The man who is made captive by some more tyrannical passion shall not suffer a heavy punishment, but he who is subdued by a weak one is deprived of all defense. For what shall we reply when He says, You saw Me hungry and fed Me not? Matthew 25:42; what excuse shall we have? We shall certainly plead poverty; yet we are not poorer than that widow, who by throwing in two mites overshot all the rest. For God requires not the quantity of the offering, but the measure of the mind; and that He does so, comes from His tender care. Let us then, admiring His lovingkindness, contribute what is in our power, that having both in this life and in that which is to come obtained in abundance the lovingkindness of God, we may be able to enjoy the good things promised to us, through the grace and lovingkindness of our Lord Jesus Christ, to whom be glory for ever and ever. Amen.
[AD 430] Augustine of Hippo on John 14:14
1. The Lord, by His promise, gave those whose hopes were resting on Himself a special ground of confidence, when He said, For I go to the Father; and whatsoever you shall ask in my name, I will do it. His proceeding, therefore, to the Father, was not with any view of abandoning the needy, but of hearing and answering their petitions. But what is to be made of the words, Whatsoever you shall ask, when we behold His faithful ones so often asking and not receiving? Is it, shall we say, for no other reason but that they ask amiss? For the Apostle James made this a ground of reproach when he said, You ask and receive not, because ye ask amiss, that you may consume it upon your lusts. James 4:3 What one, therefore, wishes to receive, in order to turn to an improper use, God in His mercy rather refuses to bestow. Nay, more, if a man asks what would, if answered, only tend to his injury, there is surely greater cause to fear, lest what God could not withhold with kindness, He should give in His anger. Do we not see how the Israelites got to their own hurt what their guilty lusting craved? For while it was raining manna on them from heaven, they desired to have flesh to eat. Numbers 11:32 They disdained what they had, and shamelessly sought what they had not: as if it were not better for them to have asked not to have their unbecoming desires gratified with the food that was wanting, but to have their own dislike removed, and be made themselves to receive aright the food that was provided. For when evil becomes our delight, and what is good the reverse, we ought to be entreating God rather to win us back to the love of the good, than to grant us the evil. Not that it is wrong to eat flesh, for the apostle, speaking of this very thing, says, Every creature of God is good, and nothing to be refused which is received with thanksgiving; 1 Timothy 4:4 but because, as he also says, It is evil for that man who eats with offense; Romans 14:20 and if so, with offense to man, how much more so if to God, to whom it was no light offense, on the part of the Israelites, to reject what wisdom was supplying, and ask for that which lust was craving: although they would not actually make the request, but murmured because it was wanting. But to let us know that the wrong lies not with any creature of God, but with obstinate disobedience and inordinate desire, it was not in swine's flesh that the first man found death, but in an apple; Genesis 3:6 and it was not for a fowl, but for a dish of pottage, that Esau lost his birthright. Genesis 25:34

2. How, then, are we to understand Whatsoever you shall ask, I will do it, if there are some things which the faithful ask, and which God, even purposely on their behalf, leaves undone? Or ought we to suppose that the words were addressed only to the apostles? Surely not. For what He has got the length of now saying is in the very line of what He had said before: He that believes in me, the works that I do shall he do also; and greater works than these shall he do; which was the subject of our previous discourse. And that no one might attribute such power to himself, but rather to make it manifest that even these greater works were done by Himself, He proceeded to say, For I go to the Father; and whatsoever you shall ask in my name, I will do it. Was it the apostles only that believed on Him? When, therefore, He said, He that believes in me, He spoke to those, among whom we also by His grace are included, who by no means receive everything that we ask. And if we turn our thoughts even to the most blessed apostles, we find that he who labored more than they all, yet not he, but the grace of God that was with him, 1 Corinthians 15:10 besought the Lord thrice that the messenger of Satan might depart from him, and received not what he had asked. 2 Corinthians 12:8 What shall we say, beloved? Are we to suppose that the promise here made, Whatsoever you shall ask in my name, I will do it, was not fulfilled by Him even to the apostles? And to whom, then, will ever His promise be fulfilled, if therein He has deceived His own apostles?

3. Wake up, then, believer, and give careful heed to what is stated here, in my name: for in these words He does not say, whatsoever you shall ask in any way; but, in my name. How, then, is He called, who promised so great a blessing? Christ Jesus, of course: Christ means King, and Jesus means Saviour! For certainly it is not any one who is a king that will save us, but only the Saviour-King; and therefore, whatsoever we ask that is adverse to the interests of salvation, we do not ask in the name of the Saviour. And yet He is the Saviour, not only when He does what we ask, but also when He refuses to do so; since by not doing what He sees to be contrary to our salvation, He manifests Himself the more fully as our Saviour. For the physician knows which of his patient's requests will be favorable, and which will be adverse, to his safety; and therefore yields not to his wishes when asking what is prejudicial, that he may effect his recovery. Accordingly, when we wish Him to do whatsoever we ask, let it not be in any way, but in His name, that is, in the name of the Saviour, that we present our petition. Let us not, then, ask anything that is contrary to our own salvation; for if He do that, He does it not as the Saviour, which is the name He bears to His faithful disciples. For He who condescends to be the Saviour of the faithful, is also a Judge to condemn the ungodly. Whatsoever, therefore, any one that believes in Him shall ask in that name which He bears to those who believe in Him, He will do it; for He will do it as the Saviour. But if one that believes in Him asks something through ignorance that is injurious to his salvation, he asks it not in the name of the Saviour; for His Saviour He will no longer be if He do anything to impede his salvation. And hence, in such a case, in not doing what He is entreated to do, His way is kept the clearer for doing what His name imports. And on that account, not only as the Saviour, but also as the good Master, He taught us, in the very prayer He gave us, what we should ask, in order that, whatsoever we shall ask, He may do it; and that we, too, might thereby understand that we cannot be asking in the Master's name anything that is inconsistent with the rule of His own instructions.

4. There are some things, indeed, which, although really asked in His name, that is, in harmony with His character as both Saviour and Master, He does not at the time we ask them, and yet He fails not to do them. For when we pray that the kingdom of God may come, it does not imply that He is not doing what we ask, because we do not begin at once to reign with Him in the everlasting kingdom: for what we ask is delayed, but not denied. Nevertheless, let us not fail in pray ing, for in so doing we are as those that sow the seed; and in due season we shall reap. Galatians 6:9 And even when we are asking aright, let us ask Him at the same time not to do what we ask amiss; for there is reference to this also in the Lord's Prayer, when we say, Lead us not into temptation. Matthew 6:9-13 For surely the temptation is no slight one if your own request be hostile to your cause. But we must not listen with indifference to the statement that the Lord (to prevent any from thinking that what He promised to do to those that asked, He would do without the Father, after saying, Whatsoever you shall ask in my name, I will do it) immediately added, That the Father may be glorified in the Son: if you shall ask anything in my name, I will do it. In no respect, therefore, does the Son act without the Father, since He so acts for the very purpose that in Him the Father may be glorified. The Father, therefore, acts in the Son, that the Son may be glorified in the Father: and the Son acts in the Father, that the Father may be glorified in the Son; for the Father and the Son are one.
[AD 444] Cyril of Alexandria on John 14:14
Undisguisedly now He says that, being Very God, He will accept exceeding readily the prayers of His own people, and will supply right gladly what things soever they desire to receive, meaning of course spiritual gifts and such as are worthy of the heavenly munificence. And not as the minister of another's benevolence, nor yet as subserving another's kindness, does He say such things; but as, with the Father, having all things in His power; and as Himself being the One through Whom are all things, both from us to God-ward, and to us-ward from Him. For this cause Paul also prays on behalf of the worthy for such supplies of benefits as are by him ever mentioned in conjunction, in the following words: Grace to you and peace from God our Father and the Lord Jesus Christ; and surely no man in his senses will ever in the face of this suppose that the Father by Himself separately grants a grace, and again the Son by Himself separately and as it were in turn does so; but the grace is one and the same, albeit it is spoken of as coming through Both. Notwithstanding, it is by the Father through the Son that all good things are wrought for the worthy, and the distribution of the Divine gifts is made; through the Son, I say, not as accepted in the rank of a servant, as we have already explained, but as conceived to be Co-Giver and Co-Supplier, and moreover as being so of a truth. For the nature of the Godhead is one, and also is believed so to be. For although it is extended to Father and Son and to the Holy Spirit, yet it has no absolute and entire severance; I mean, into each of the Persons indicated. For we shall be orthodox in believing that the Son is naturally both of the Father and in the Father, and that the own Spirit of the Father and of the Son, that is, the Holy Spirit, is both of and in the Father. So then, forasmuch as the Godhead of Their nature both is and is conceived of as One, Their gifts will be supplied to the worthy through the Son from the Father in the Spirit, and our offerings will be carried to God manifestly through the mediation of the Son: for no one cometh unto the Father but through Him, as to be sure He also Himself fully confesses. So then the Son both has become and is the Door and the Way as well of our friendship as of our progress towards God the Father, and the Co-Giver as well as Distributer of His bounty, forasmuch as it proceeds from a single and common munificence. For one is the nature of the Godhead in the person and substance both of the Father and of the Son and of the Holy Ghost. And forasmuch as it was unwonted in a way with them of old time, and as yet foreign to their practice, to approach the Father through the Son, He teaches this also for our profit, and laying first in His own disciples a foundation as it were of the structure, He implants in them both faith in this and knowledge, and despatches to ourselves instruction both how we are to pray and wherein lies our hope. For He promises that He will Himself give us what we ask in prayer; a proof of the Godhead in His nature, and of the royal authority inherent in Him; adding this to the other proofs thereof.
[AD 258] Cyprian on John 14:15
From which an example is given us to avoid the way of the old man, to stand in the footsteps of a conquering Christ, that we may not again be incautiously turned back into the nets of death, but, foreseeing our danger, may possess the immortality that we have received. But how can we possess immortality, unless we keep those commands of Christ whereby death is driven out and overcome, when He Himself warns us, and says, "If thou wilt enter into life, keep the commandments? " And again: "If ye do the things that I command you, henceforth I call you not servants, but friends." Finally, these persons He calls strong and stedfast; these He declares to be founded in robust security upon the rock, established with immoveable and unshaken firmness, in opposition to all the tempests and hurricanes of the world. "Whosoever," says He, "heareth my words, and doeth them, I will liken him unto a wise man, that built his house upon a rock: the rain descended, the floods came, the winds blew, and beat upon that house; and it fell not: for it was founded upon a rock." We ought therefore to stand fast on His words, to learn and do whatever He both taught and did. But how can a man say that he believes in Christ, who does not do what Christ commanded him to do? Or whence shall he attain to the reward of faith, who will not keep the faith of the commandment? He must of necessity waver and wander, and, caught away by a spirit of error, like dust which is shaken by the wind, be blown about; and he will make no advance in his walk towards salvation, because he does not keep the truth of the way of salvation.

[AD 398] Didymus the Blind on John 14:15-17
(Didym. De Spiritu Sancto.) But the Holy Ghost was another Comforter: differing not in nature, but in operation. For whereas our Saviour in His office of Mediator, and of Messenger1, and as High Priest, made supplication for our sins; the Holy Ghost is a Comforter in another sense, i. e. as consoling our griefs. But do not infer from the different operations of the Son and the Spirit, a difference of nature. For in other places we find the Holy Spirit performing the office of intercessor2 with the Father, as, The Spirit Himself intercedeth for us. (Rom. 8:26) And the Saviour, on the other hand, pours consolation into those hearts that need it: as in Maccabees, He strengthened those of the people that were brought low. (1 Macc. 14:15)

[AD 407] John Chrysostom on John 14:15-17
Our Lord having said, Whatsoever ye shall ask in My name, that I will do; that they might not think simply asking would be enough, He adds, If ye love Me, keep My commandments. And then I will do what ye ask, seems to be His meaning. Or the disciples having heard Him say, I go to the Father, and being troubled at the thought of it, He says, To love Me, is not to be troubled, but to keep My commandments: this is love, to obey and believe in Him who is loved. And as they had been expressing a strong desire for His bodily presence, He assures them that His absence will be supplied to them in another way: And I will pray the Father, and He will give you another Comforter.

(Hom. lxxiv. 2) He says, I will ask the Father, to make them believe Him: which they could not have done, had He simply said, I will send.

(Hom. lxxiv) But what had He more than the Apostles, if He could only ask the Father to give others the Spirit? The Apostles did this often even without praying.

(Hom. lxxv. 1) That He may abide with you for ever. The Spirit does not depart even at death. He intimates too that the Holy Ghost will not suffer death, or go away, as He has done. But that the mention of the Comforter might not lead them to expect another incarnation, a Comforter to be seen with the eye, He adds, Even the Spirit of truth, Whom the world cannot receive, because it seeth Him not, neither knoweth Him.

(Hom. lxxv. 1) The Spirit of truth He calls Him, because He unfolds the figures of the Old Testament. The world are the wicked, seeing is certain knowledge; sight being the most certain of the senses.

(Hom. lxxv. 1) As if He said, He will not dwell with you as I have done, but will dwell in your souls.

(Hom. lxxv. 1) This speech levels at a stroke, as it were, the opposite heresies. The word another, shows the distinct personality of the Spirit: the word Paraclete, His consubstantiality.

(Hom. lxxv. 1) When He had cleansed His disciples by the sacrifice of His passion, and their sins were remitted, and they were sent forth to dangers and trials, it was necessary that they should receive the Holy Spirit abundantly. But they were made to wait some time for this gift, in order that they might feel the want of it, and so be the more grateful for it when it came.

[AD 407] John Chrysostom on John 14:15
1. We need everywhere works and actions, not a mere show of words. For to say and to promise is easy for any one, but to act is not equally easy. Why have I made these remarks? Because there are many at this time who say that they fear and love God, but in their works show the contrary; but God requires that love which is shown by works. Wherefore He said to the disciples, If you love Me, keep My commandments. For after He had told them, Whatsoever you shall ask, I will do it, that they might not deem the mere asking to be availing, He added, If you love Me, then, He says, I will do it. And since it was likely that they would be troubled when they heard that, I go to the Father, He tells them to be troubled now is not to love, to love is to obey My words. I have given you a commandment that you love one another, that you do so to each other as I have done to you; this is love, to obey these My words, and to yield to Him who is the object of your love.

And I will ask the Father, and He shall give you another Comforter. Again His speech is one of condescension. For since it was probable, that they not yet knowing Him would eagerly seek His society, His discourse, His presence in the flesh, and would admit of no consolation when He was absent, what says He? I will ask the Father, and He shall give you another Comforter, that is, Another like Me. Let those be ashamed who have the disease of Sabellius, who hold not the fitting opinion concerning the Spirit. For the marvel of this discourse is this, that it has stricken down contradictory heresies with the same blow. For by saying another, He shows the difference of Person, and by Paraclete, the connection of Substance. But why said He, I will ask the Father? Because had He said, I will send Him, they would not have so much believed and now the object is that He should be believed. For afterwards He declares that He Himself sends Him, saying, Receive the Holy Ghost John 20:22; but in this place He tells them that He asks the Father, so as to render His discourse credible to them. Since John says of Him, Of His fullness have all we received John 1:16; but what He had, how receives He from another? And again, He shall baptize you with the Holy Ghost and with fire. Luke 3:16 But what had He more than the Apostles, if He was about to ask It of His Father in order to give It to others, when they often even without prayer appear to have done thus? And how, if It is sent according to request from the Father, does It descend of Itself? And how is that which is everywhere present sent by Another, that which divides to every man severally as He will 1 Corinthians 12:11, and which says with authority, Separate Me Paul and Barnabas? Acts 13:2 Those ministers were ministering unto God, yet still It called them authoritatively to Its own work; not that It called them to any different work, but in order to show Its power. What then, says some one, is, 'I will ask the Father?'? (He says it) to show the time of Its coming. For when He had cleansed them by the sacrifice, then the Holy Ghost lighted upon them. And why, while He was with them, came it not? Because the sacrifice was not yet offered. But when afterwards sin had been loosed, and they were being sent forth to dangers, and were stripping themselves for the contest, then need was that the Anointer should come. But why did not the Spirit come immediately after the Resurrection? In order that being greatly desirous of It, they might receive It with great joy. For as long as Christ was with them, they were not in tribulation; but when He departed, being made defenseless and thrown into much fear, they would receive It with much readiness.

He remains with you. This shows that even after death It departs not. But lest when they heard of the Paraclete, they should imagine a second Incarnation, and expect to see It with their eyes, He sets them right by saying, Whom the world cannot receive, because it sees Him not. He will not be with you as I have been, but will dwell in your very souls; for this is the, shall be in you. He calls it the Spirit of truth; thus explaining the types in the Old Testament. That He may be with you. What is, may be with you? That which He says Himself, that I am with you. Matthew 28:20 Besides, He also implies something else, that the case of the Spirit shall not be the same as Mine, He shall never leave you. Whom the world cannot receive, because it sees Him not. Why, what is there belonging to the other Persons that is visible? Nothing; but He speaks here of knowledge; at least He adds, neither knows Him. For He is wont, in the case of exact knowledge, to call it sight; because sight is clearer than the other senses, by this He always represents exact knowledge.  By world, He here speaks of the wicked, thus too comforting the disciples by giving to them a special gift. See in how many particulars He raised His discourse concerning It. He said, He is Another like Me; He said, He will not leave you; He said, Unto you alone He comes, as also did I; He said, that He remains in you; but not even so did He drive out their despondency. For they still sought Him and His society. To cure then this feeling, He says,
[AD 407] John Chrysostom on John 14:15
At all times it is works and actions that we need, not a mere show of words. It is easy for anyone to say or promise something, but it is not so easy to act on that word or promise.… “If you love me,” Christ said, “keep my commandments.” … I have commanded you to love one another and to do to one another as I have done to you. To love me is to obey these commands and to submit to me, your beloved.

[AD 430] Augustine of Hippo on John 14:15-17
(Tract. lxxiv. 4) Wherein He shows too that He Himself is the Comforter. Paraclete means advocate, and is applied to Christ: We have an Advocate with the Father, Jesus Christ the righteous. (1 John 2:1)

(contra Serm. Arrian. c. xix.) Yet to show that His works are inseparable from His Father's, He says below, When I shall go, I will send Him unto you.

(Tract. lxxiv. 1) This is the Holy Ghost in the Trinity, Whom the Catholic faith professes to be consubstantial and coeternal with the Father and the Son.

(Tract. lxxiv. 4) Thus the world, i. e. the lovers of the world, cannot, He says, receive the Holy Spirit: that is to say, unrighteousness cannot be righteous. The world, i. e. the lovers of the world, cannot receive Him, because it seeth Him not. The love of the world hath not invisible eyes wherewith to see that, which can only be seen invisibly. It follows: But ye know Him, for He dwelleth (manebit) with you. And that they might not think this meant a visible dwelling, in the sense in which we use the phrase with respect to a guest, He adds, And shall be in you.

(Tract. lxxiv. 5) To be in a place is prior to dwelling. Be in you, is the explanation of dwell with you: i. e. shows that the latter means not that He is seen, but that He is known, He must be in us, that the knowledge of Him may be in us. We see the Holy Ghost then in us, in our consciences.

(contr. Serm. Arrian. c. xix.) Comforter, the title of the Holy Spirit, the third Person in the Trinity, the Apostle applies to God: God that comforteth those that are cast down, comforted us. (2 Cor. 7:6) The Holy Spirit therefore Who comforts those that are cast down, is God. Or if they will have this said by the Apostle of the Father or the Son, let them not any longer separate the Holy Spirit from the Father and the Son, in His peculiar office of comforting.

(Tract. lxxiv. c. 1) But when the love of God is shed abroad in our hearts by the Holy Ghost which is given unto us, (Rom. 5:6) how shall we love and keep the commandments of Christ, so as to receive the Spirit, when we are not able to love or to keep them, unless we have received the Spirit? Does love in us go first, i. e. do we so love Christ and keep His commandments as to deserve to receive the Holy Spirit, and to have the love of God the Father shed abroad in our hearts? This is a perverse opinion. For he who does not love the Father, does not love the Son, however he may think he does. (c. 2). It remains for us to understand, that he who loves has the Holy Spirit, and by having Him, attains to having more of Him, and by having more of Him, to loving more. The disciples had already the Spirit which our Lord promised; but they were to be given more of Him: they had Him secretly, they were to receive Him openly. The promise is made both to him who has the Spirit, and to him who has Him not; to the former, that he shall have Him; to the latter, that He shall have more of Him.

[AD 430] Augustine of Hippo on John 14:15
How, then, did the apostles love, but in the Holy Spirit? And yet they are commanded to love him and keep his commandments before they have received him and, in fact, in order to receive him. And yet, without having that Spirit, they certainly could not love him and keep his commandments. We are therefore to understand that he who loves already has the Holy Spirit, and by what he has he becomes worthy of a fuller possession, that by having more he may love more. The disciples, therefore, already had that Holy Spirit whom the Lord promised, for without him they could not call him Lord. But they had him not as yet in the way promised by the Lord.… He was yet to be given them in an ampler measure.

Source: TRACTATES ON THE GOSPEL OF JOHN 74.1-2
[AD 444] Cyril of Alexandria on John 14:15
Having ordained that when men pray they must ask in His Name and promising that He will Himself supply to them that ask whatsoever they desire to receive, He takes great thought not to seem to speak falsehood, having in view the unholy slanders of such as are wont to be captious. For a man can see, and best out of the Sacred Writings themselves, that some approach and ask earnestly in His Name, and notwithstanding in no wise receive; because God is not ignorant of what is fitting for each and profitable for the askers. Therefore to the end that our Lord Jesus the Christ might clearly exhibit who they are in reference to whom the word has been spoken and stands good, and to whom is due the grace of the promise; He straightway introduced the mention of the persons who love Him, in whose case the promise will assuredly be fulfilled, and conjoins with His saying the exactly-defined keeper of the law, showing that unto such and not unto others shall the promise of kindness and the bestowal of the spiritual blessings hold good and come to pass. For that oftentimes the bounteous hand of God is shortened in hesitation, cutting off from them that will not ask aright the consummation of their hopes, thou wilt easily understand, from what the disciple of Christ is at pains to write on this wise: Ye ask, and receive not, because ye ask amiss, when ye will spend it in your pleasures. Wherefore also again he says, about them that are wont to be double-minded: For let not that man think that he shall receive anything of the Lord; for [he is] a double-minded man, unstable in all his ways. For to them that ask for the grace that is from above, not for establishing of virtue, but for enjoyment of carnal pleasure and worldly lusts, God well-nigh shuts fast His ear, and in no wise grants them anything; for what things soever He forbids and wholly casts out by reason of the abomination that is in them, how could He grant them to any? And the spring of all sweetness, how could it give forth a bitter stream? But that unto the lovers of spiritual gifts with rich and readiest hand He distributes blessings, thou shalt easily perceive, when thou hearest Him saying unto them by the mouth of Isaiah the prophet: While thou art yet speaking, 1 will say, What is it? and by the voice of the Psalmist: The eyes of the Lord are upon the righteous, and His ears are open unto their prayer.

So having determined and expressly declared that the enjoyment of the heavenly blessings, supplied, that is, through Him by the Father, is both due to them that love Him, and in very truth shall be theirs; He straightway goes on to describe the power of love, and instructs us excellently and irreproachably, for our profit, with intent that we should devote ourselves to the pursuit thereof. For albeit a man say that he loves God, he will not therefore straightway win the credit of truly loving, forasmuch as the power of virtue stands not in bare speech, nor is the beauty of piety towards God fashioned in naked words; but rather it is really distinguished by means of good deeds effected and an obedient temper; and the keeping of the Divine precepts best gives living expression to love towards the Divinity, and presents the picture of a virtue wholly living and true; not sketched out in mere sounds that flow from the tongue, as we have said, but gleaming as it were and altogether radiant with brilliant colours, to wit, the portraits of good works. And indeed our Lord Jesus the Christ shows us this plainly, when He says: Not every one that saith unto Me, Lord, Lord, shall enter into the kingdom of heaven; but he that doeth the will of My Father, Which is in heaven. For the proof of faith lies not in barren words or professions, but in the qualities of acts, and indeed the Holy Scripture says that it is dead when the works do not follow therewith. For the knowledge that God is One, it says, we shall find, not only in human minds, but in the unclean devils themselves; who also shudder, even involuntarily, at the power of Him that made them. Howbeit to keep the radiance of their acts concurrent with their faith is manifestly the beauty and ornament of those only who truly love God. So then the proof of love and the most perfect definition of faith is the observance of the Evangelic decrees and the keeping of the Divine precepts. And perhaps it would be in no wise difficult to add other things hereunto, akin in their drift; only that I suppose they do not suit the present occasion. Wherefore we must once more betake ourselves to such points as are more suitable to what lies before us. If ye love Me, He says, ye will keep My commandments. For indeed thou must understand once again and call well to mind that oftentimes, when conversing with His own disciples or even with the Jews themselves, He would say: The words that I speak are not Mine, but His Who sent Me; and again: I speak not from Myself, but the Father Which sent Me, He hath given Me a commandment, what I should say, and what I should speak; and again: The things therefore which I speak, are not Mine, but His Who sent Me. And yet now again, notwithstanding He has confessed at large, up and down His discourses, that the words He addressed to us are God the Father's, He here says they are His own commandments, which He has spoken to us. And no one that has sense will suppose that He speaks falsely, for let not this thought come into the mind of a Christian; and moreover He will of course speak truly, forasmuch as He is Himself the Truth. For it was not in the manner of one of the prophets, as if with the rank of a minister and a servant, that He conveyed the message from the Father to us; but as bearing such likeness to Him that not even in word was He haply observed to differ, but rather naturally to speak on such wise as the Father Himself might peradventure talk with us. For the exact similarity of essence leads us to believe that the Son also corresponds in His utterances to Him that begat Him; and inasmuch as He is Himself the Word and Wisdom and Purpose of God the Father, He says that He has received commandment what to say and what He shall speak. For we also ourselves individually see that our own minds well-nigh even lay a commandment on our speech uttered through words, as it proceeds to the world without, that it shall interpret what is in the mind itself. Small indeed is the force of the illustration as applied to God; but notwithstanding this, by taking the analogy of human things to assure us of the things that transcend them, we apprehend the Divine Mysteries as it were in a mirror and darkly.
[AD 444] Cyril of Alexandria on John 14:15
Having determined and expressly declared that the enjoyment of the heavenly blessings (supplied, that is, through him by the Father) is both due to those who love him and in very truth shall be theirs, he immediately goes on to describe the power of love. He provides excellent and irreproachable instruction to us for our profit with the intent that we should devote ourselves to its pursuit. For even if a person says that he loves God, he will not immediately merit credit for having true love of God, since the power of virtue does not stand on bare speech alone, nor piety on naked words. Rather, it is distinguished by performance of good deeds and an obedient disposition. Keeping the divine commandments is the best way to give living expression to our love toward God. It presents the picture of a life lived in all its fullness and truth. It is not a life sketched out in mere sounds that flow from the tongue. It gleams instead with the altogether radiant and brilliant colors that paint a portrait of good works.

(v. Mor.) The Holy Spirit kindles in every one, in whom He dwells, the desire of things invisible. And since worldly minds love only things visible, this world receiveth Him not, because it rises not to the love of things invisible. In proportion as secular minds enlarge themselves by the spread of their desires, in that proportion they narrow themselves, with respect to admitting Christ.

(ii. Mor.) But if the Holy Spirit abides in the disciples, how is it a special mark of the Mediator that He abides in Him. (supr. 1:32. ἐπʼ αὐτὸν) We shall better understand, if we distinguish between the different gifts of the Spirit. In respect of those gifts without which we cannot attain to salvation, the Holy Spirit ever abides in all the Elect: but in respect of those which do not relate to our own salvation, but to the procuring that of others, He does not always abide in them. For He sometimes withdraws His miraculous gifts, that His grace may be possessed with humility. Christ has Him without measure and always.

There are not then either three Fathers, or three Sons, or three Paracletes, but one Father, and one Son, and one Paraclete. Wherefore also the Lord, when He sent forth the apostles to make disciples of all nations, commanded them to "baptize in the name of the Father, and of the Son, and of the Holy Ghost," not unto one [person] having three names, nor into three [persons] who became incarnate, but into three possessed of equal honour.

This promise shows once again Christ’s consideration. Because his disciples did not yet know who he was, it was likely that they would greatly miss his companionship, his teaching, his actual physical presence, and be completely disconsolate when he had gone. Therefore he said, “I will ask the Father, and he will give you another Counselor,” meaning another like himself.… They received the Spirit after Christ had purified them by his sacrifice. The Spirit did not come down on them while Christ was still with them because this sacrifice had not yet been offered. But when sin had been blotted out and the disciples, sent out to face danger, were preparing themselves for the battle, they needed the Holy Spirit’s coming to encourage them. If you ask why the Spirit did not come immediately after the resurrection, this was in order to increase their gratitude for receiving him by increasing their desire. They were troubled by nothing as long as Christ was with them, but when his departure had left them desolate and very much afraid, they would be most eager to receive the Spirit.

I will confer the grace of the Holy Spirit, he says, so that you may always have it with you to teach you the truth. He speaks of another Advocate, as of another instructor, a comforter. This is a doctrine for those in dire straits because the Spirit, through its grace, will make the afflictions inflicted on them by people lighter. And, as a consolation, through its gifts, it will enable them to easily endure their afflictions. This is what actually happened. Indeed, the more his disciples feared death before, the more they rejoiced in tribulations after the descent of the Spirit. He calls it “Spirit of truth” since it teaches nothing but the truth, nor can it ever change to the contrary in order to teach anything different from the truth. He says “another” in relation to himself, for while he was among them, he certainly filled the same role for them. In addition they received from the Holy Spirit the confirmation of all those things that he had taught them when he was present. Thus our Lord said, “But you will receive power when the Holy Spirit has come on you. And you will be my witness in Jerusalem, in all Judea and among the Samaritans, and all nations.”

Source: DISCOURSES AGAINST THE ARIANS 19
[AD 444] Cyril of Alexandria on John 14:16
He mingles once more the human with the Divine, and neither reverts to the pure glory of the Godhead, nor yet altogether confines His range within the limits of humanity, but traverses both, wondrously and at the same time indistinguishably too, forasmuch as He is at once both God and man. For He was God by His nature, inasmuch as He was the Fruit of the Father and the Effulgence of His essence; and again, He was man, inasmuch as He has become Flesh. Accordingly He speaks as God and at the same time as man: for after this manner it was possible to preserve duly such forms of language as befitted the dispensation in flesh. Notwithstanding, while we are searching for the meaning of the passage before us, we say this: that at this point also, of necessity, our Lord has introduced the mention of God the Father, for the building up of their faith, and for the exceeding profit of the hearers; as indeed the argument will demonstrate as it proceeds. For when He bade us ask in His Name, and revealed, along with the other truths, a manner of praying unused among the ancients, promising withal even very earnestly that He will give whatsoever things we wish to receive: with intent that He might not seem thereby to thrust aside the Person of God the Father, nor yet to curtail the power of Him Who begat Him, the power (I mean) of satisfying the aspirations of the saints, He said that the Father would be a Co-Supplier for our profit, and would join in bestowing on us the Paraclete: adding also the words "I will ask," as man; and referring peculiarly to the whole Divine and unspeakable nature what befits it especially, as in the Person of God the Father. For this was His custom, as we have oftentimes said already in the foregoing parts of this work.

Another Paraclete, however, is the name He gives to the Spirit that proceeds from the essence of God the Father and from that of Himself. For the kind of the essence is the same in the case of Both, not excluding the Spirit, but allowing the manner of His distinctness to be understood as lying solely in His being and subsisting in a separate personality. For the Spirit is not a Son, but we will accept in faith verily and properly to be and to subsist as That Which He is; for He is the Spirit of the Father and of the Son. But [the Son] knowing that He Himself also both is in truth a Paraclete and is so named in the Sacred Writings, He calls the Spirit another Paraclete; not on the ground that the Spirit can skill to effect in the Saints something else perchance more than what He also can, Whose Spirit He both is and is called. And that the Son also Himself both was named and is a Paraclete, John will bear record, in his own compositions, when he says: These things say I unto you, that ye may not sin. And if any man sin, we have a Paraclete with the Father, Jesus Christ the righteous: and He is the propitiation for our sins. So Jesus calls the Spirit another Paraclete, willing Him to be conceived of as possessing the attributes of a proper personality; albeit having so close a likeness to Himself, and able so to work in exact correspondence what things soever He Himself might haply work, as that He might seem to be the Son Himself and no whit different: for He is His Spirit. And indeed Jesus called Him the Spirit of Truth, saying also in the discourse before us that He is Himself the Truth.

But any one will naturally say to those who suppose the Son alien to the essence of God the Father: "How is it, pray, that the Father gives the Spirit of Truth, that is, of the Son, not as foreign or alien, but as His own Spirit; notwithstanding that according to you He has the kind of His essence distinct from that of the Son, and, for of this there is no question, the Spirit is the Son's? And once more, how is it, if it be so that the Son is of another essence, that He gives the Spirit of the Father as His own?" For it is written that He breathed on His disciples, saying, Receive ye the Holy Ghost. So then will not a man suppose, and very rightly, or rather will he not be even firmly convinced, that the Son, being essentially partaker of the natural excellences of God the Father, has the Spirit after the same manner as the Father also would be understood to have Him: that is, not as something added or from without, for it were simple or rather mad to hold such an opinion; but as each of us has within himself his own breath, and pours it forth without from the inmost parts of his body? For indeed it was for this cause that Christ breathed on them even bodily, showing that as the breath proceeds bodily from the human mouth, so also from the Divine essence the [Spirit] from Him is in God-befitting manner poured forth. Forasmuch then as He is the Spirit both of God the Father and of the Son, how can it be but that the power They thus possess at once in division and in conjunction will be altogether one? For the Father is a Father and not a Son, and the Son is a Son and not a Father; notwithstanding, the Father is in the Son, and the Son in the Father; moreover, it is not the Father separately by Himself, or the Son separately by Himself, Who gives the Paraclete or the Holy Spirit, but rather He is supplied to the saints from the Father through the Son. For indeed on this account [we must understand that] when the Father is said to give, the Son also gives, through Whom are all things; and that when the Son is said to give, the Father also gives, of Whom are all things.

But that the Spirit is both Divine and not of another essence, in reference I mean to the Father and the Son, is I imagine doubtful to no one who is right-minded; and furthermore a necessary argument will convince us thereof. For if a man say that the Spirit is not of the essence of God, how then henceforward would the creature in receiving the Spirit be a partaker of God? And after what manner shall we be entitled temples of God, and be so, if we receive a created or an alien spirit, and not rather That Which is of God? And how are those who have a share of the Spirit partakers of the Divine nature, according to the words of the sacred writers, if He is in the number of the things that are made, and does not rather proceed for us from the Divine nature itself; not passing through it unto us, as something foreign to it, but so to speak becoming in us a certain quality of the Godhead, and dwelling in the saints, and remaining for ever----[as He does] if by cleansing the eye of their understanding by all goodness, and by unyielding earnestness in the pursuit of every virtue, they preserve the grace in their hearts. For Christ says that the Spirit is uncontainable and invisible for them that are in the world, that is, for those that savour of the things in the world, and choose to love the things that are on earth; yet that He is containable and easily beheld by the saints. For what reason? They who have an uncleanness hard to be washed out of them, and who have filled their own mind as it were with some unhealthy humour, do not narrowly consider the beauty of the Divine nature, nor yet accept the law of the Spirit, forasmuch as they are wholly tyrannised over by the passions of the flesh; whereas the good and sober, keeping their heart free from the evils that are in the world, voluntarily induce the Paraclete to dwell within themselves, and after receiving Him keep Him and (so far as it is attainable by men) behold Him spiritually, winning therefrom something large and great and enviable for their prize. For He will sanctify them, and will make them at once fulfillers of all good things, and will release them from the shame of man-befitting slavery, and will endue them with the prerogative of the adoption of sons. And Paul will bear witness to this, saying: And because ye are sons, God sent forth the Spirit of His Son into your hearts, crying, Abba, Father.

And that which bestows sonship upon the creation could not be alien from the Son. For we should have otherwise to seek another spirit, so that by him this Spirit might be joined to the Word. But that would be absurd. The Spirit, therefore, does not belong to things originated. He pertains to the Godhead of the Father, and in him the Word makes things originated divine. But he in whom creation is made divine cannot be outside the Godhead of the Father.

As the Paraclete he reflects the goodness of the Paraclete (the Father)29 who sent him, and his own dignity reveals the majesty of him from whom he proceeded.… If we are illumined by divine power and fix our eyes on the beauty of the image of the invisible God, and [if we] through the image are led up to the indescribable beauty of its source, it is because we have been inseparably joined to the Spirit of knowledge. He gives those who love the vision of truth the power that enables them to see the image. And this power is himself. He does not reveal it to them from outside sources but leads them to knowledge personally: “No one knows the Father except the Son,” and “No one can say ‘Jesus is Lord’ except in the Holy Spirit.” Notice that it does not say through the Spirit but in the Spirit. It also says, “God is Spirit, and those who worship him must worship in spirit and truth,” and “in your light do we see light,” through the illumination of the Holy Spirit, “the true light that enlightens every one who comes into the world.” He reveals the glory of the Only Begotten in himself, and he gives true worshipers the knowledge of God in himself. The way to divine knowledge ascends from one Spirit through the one Son to the one Father.

The apostle says, “The love of God is shed abroad in our hearts by the Holy Spirit who is given to us.” How then does the Lord say here, “If you love me, keep my commandments, and [then] I will ask the Father, and he will give you another Comforter”? Notice he says this about the Holy Spirit. But without the Spirit we can neither love God nor keep his commandments. How can we love so that we will receive him when, without him, we cannot love at all? How can we keep the commandments so that we will receive him when, without him, we have no power to keep them? Or is it the case that the love by which we love Christ has a prior place in us so that by loving Christ in this way and keeping his commandments we become worthy of receiving the Holy Spirit so that the love of God the Father (not of Christ, which we already had) may be shed abroad in our hearts by the Holy Spirit who is given to us? That kind of thinking is all wrong. For whoever believes he loves the Son without loving the Father loves some figment of his own imagination, not the Son.…We should therefore understand that whoever loves already has the Holy Spirit, and by having him he becomes worthy of having even more of him. And the more he has the Spirit the more he loves. The disciples already had the Holy Spirit whom the Lord promised.… But they did not yet have him in the way the Lord promised. And so they had him and did not have him inasmuch as they did not have to the extent that they would later. They had him in a more limited sense. He was later to be given to them more fully. They had him in a hidden way, but he was yet to be given to them more openly.… Let us admit then that without the Holy Spirit we can neither love Christ nor keep his commandments. [But it is also true that] the less experience we have of the Spirit’s presence, the less we can do, while the fuller our experience of the Spirit is, the greater is our ability. And so this is no empty promise of Jesus here—either to the one who does not have the Holy Spirit or to the one who has him. For the promise is made to the one who does not have the Spirit so that he may have him, and it is made to the one who does have the Spirit so that he may have him more abundantly.

But they were made to wait some time for this gift, in order that they might feel the want of it, and so be the more grateful for it when it came.

(Hom. lxxv. 1) At the first He said, Whither I go ye shall come; but as this was a long time off, He promises them the Spirit in the interval. And as they knew not what that was, He promises them that they most desired, His own presence, I will come to you: but intimates at the same time that they are not to look for the same kind of presence over again: Yet a little while, and the world seeth Me no more: as if He said, I will come to you, but not to live with you every day as I did before. And, I will come to you alone, He says, thus preventing any inconsistency with what He had said to the Jews: Henceforth ye shall not see Me.

(Tr. lxxv. 1) That no one might think, because our Lord was about to give the Holy Spirit, that He would therefore not be present Himself in Him, He adds, I will not leave you comfortless. The Greek word ὀρφανοὶ signifies "wards." Although then the Son of God has made us the adopted sons of the Father, yet here He Himself shows the affection of a Father towards us.

(Tr. lxxv. 2) For the world saw Him then with the carnal eye, manifest in the flesh, though it did not see the Word hidden under the flesh. But after the resurrection He was unwilling to show even His flesh, except to His own followers, whom He allowed to see and to handle it: Yet a little while, and the world seeth Me no more; but ye shall see Me. But, inasmuch as the world, by which are meant all who are aliens from His kingdom, will see Him at the last judgment, it is better perhaps to understand Him here as pointing to that time, when He will be taken for ever from the eyes of the wicked, to be seen thenceforth by those who love Him. A little while, He says, for that which seems a long time to men, is but a moment in the eyes of God.
Because I live, ye shall live also.

(Tr. lxxv. 3) But why does He speak of life as present to Him, future to them? Because His resurrection preceded, theirs was to follow. His resurrection was about so soon to take place, that He speaks of it as present; theirs being deferred till the end of the world, He does not say ye live, but ye shall live. Because He lives, therefore we shall live: As by man came death, by man came also the resurrection of the dead. (1 Cor. 15:21) It follows: In that day (the day of which He saith, ye shall live also) ye shall know, i. e. whereas now ye believe, then ye shall see, that I am in the Father, and ye in Me, and I in you. For when we shall have attained to that life in which death is swallowed up, then shall be finished that which is now begun by Him, that He should be in us, and we in Him.

(Tract. lxxv. 5) He that hath them in mind, and keepeth them in life; he that hath them in words, and keepeth them in works; he that hath them by hearing, and keepeth them by doing; he that hath them by doing, and keepeth them by persevering, he it is that loveth Me. Love must be shown by works, or it is a mere barren name.

(Tract. lxxv. 5) I will love him, as if now He did not love him. What meaneth this? He explains it in what follows: And will manifest Myself unto him, i. e. I love him so far as to manifest Myself to him; so that, as the reward of his faith, he will have sight. Now He only loves us so that we believe; then He will love us so that we see. And whereas we love now by believing that which we shall see, then we shall love by seeing that which we have believed.

(ad Paul. de videndo Dei, Ep. 112:100, 10) He promises to show Himself to them that love Him as God with the Father, not in that body which He bore upon earth, and which the wicked saw.

[AD 444] Cyril of Alexandria on John 14:18
Of necessity our Lord Jesus the Christ at this point finishes the discourse touching the Holy and Consubstantial Trinity. For He has already shown before, setting forth both words and facts for assurance unto them that love Him, both that He is in His nature God and is begotten of God the Father, and is of equal might and like mind with Him. For to this end He also at one time said: What I speak, I speak not from Myself; and at another time again: If I do not the works of My Father, believe Me not. But if I do them, though ye believe not Me, believe My works. But besides these things it was in no small measure needful also that men should receive the right and irreproachable doctrine with reference to the Holy Spirit Himself; for so might the minds of His hearers be directed wholly unto Tightness of faith. Therefore I will set forth in few words what Christ teaches us by the passage before us. By saying that "Another" shall be sent unto us from God the Father, He once more, in accordance with His careful and wise plan, renders the expression of the faith secure. For it was only likely that some, not rightly understanding what was said, would think that He meant that the Holy Spirit was not of the essence of God (as in fact some of the witless did suppose), but that He was in His nature something different; for to say "Another," among the more ignorant sort at least, might carry the appearance of some such ground for its use. So with intent to exhibit clearly that He does not wish the kind of distinctness which the Spirit possesses to be understood in any other way, save solely in virtue of His being in a peculiar and proper sense that which His Name implies, for the Spirit is a Spirit and not a Son, even as the Son is a Son and not a Father; after saying that the Paraclete shall be sent forth, He promises that He will come Himself; showing that the Spirit is not something other than what He is Himself, forasmuch as He is a proper Spirit proceeding from the Father, and is conceived of as the Son's, and for this cause is also called His Mind. For example, Paul says, signifying withal this very thing: But we have the Mind of Christ. So then, understanding the matter rightly and without all error, and rejecting as ungainly all perversion in any direction contrary to what is reasonable, and following the words of the inspired Scripture, we say that He is not something different from the Son so far as regards natural identity, but the same; yet with characteristics both distinct and personal. For, so understanding it, I imagine, the inspired Paul also oftentimes mingles Them and introduces Either as identical with the Other; the Paraclete, I mean, and the Son. For thou wilt find him saying: But if any man hath not the Spirit of Christ, he is none of His, and again directly after: And if Christ is in you, the body is dead because of the sin; but the Spirit is life because of righteousness. Hearest thou how he expressly confesses that they have Christ who have received His Spirit? And he says also in another place: For I think that I also have the Spirit of God. And he who spake this unto us, also says: If ye seek a proof of Christ That speaketh in Me; and oftentimes prays that in us also, who have believed, Christ may dwell by faith, howbeit himself receiving the Holy Spirit. And let no one suppose that we say that he annuls the fixity of name or person in respect of each, or that he says that the Son is not a Son but a Spirit, or at least that he does not know the Spirit as Spirit, but says He is a Son; this was not the aim in his mind, and indeed neither do we so believe. For he knows how to count the Persons of the Holy and Coessential Trinity, and teaches that each of the Persons signified subsists in His proper distinctness: notwithstanding he proclaims clearly that the Holy Trinity is fixed in absolute identity. Else how ean it be that the Spirit is and is called God? For do ye not know, he says, that ye are a temple of God, and the Spirit of God dwelleth in you? But if, forasmuch as the Spirit dwelleth in us, we are made temples of God, how can the Spirit not be of God, i.e. of His Essence, whereas He makes God to dwell in us through Himself? So then by way of showing that the Spirit is not alien from His own Nature, the Only-begotten, having said that the Paraclete is being sent forth from the Father for the Saints, promises that He will come Himself and fill the place of a father, to the end that they be not found like some orphans destitute of the assistance of one to stand forth for them, and for this cause be found henceforth easy to be taken in the snares of the devil, and exceedingly easily assailed by the offences in the world, for all they be many and come as of necessity, by reason of the ungovernable madness of them that bring them to pass. So then for a shield and an irrefragable security unto our souls, the Father has given the Spirit of Christ, to fulfil in us His grace and presence and power. For it were impossible for a man's soul to effect ought that is good, or to have power over its own passions, or to escape the great subtilty of the snare of the devil, if it were not fortified by the grace of the Holy Spirit, and had not Christ Himself by reason thereof within itself. And indeed the inspired Psalmist? composing for us through the wisdom that was in him his thanksgivings on this behalf, cried aloud unto God: Lord, Thou didst crown us as with a shield of favour----meaning by a shield of favour nothing else than the Holy Spirit Who shields us, and constrains us, by gifts of unexpected strength, to [the fulfilling of] the good pleasure of God. And so He promises that none the less He will be present and will help through the Spirit them that believe on Him, albeit He ascend into the very heavens, after His Revival from the dead, now to appear in the presence of God for us, according to the words of Paul.
[AD 444] Cyril of Alexandria on John 14:18
It is impossible for one’s soul to accomplish anything good, or to have power over its own passions or to escape the great subtlety of the devil’s snare if the soul is not fortified by the grace of the Holy Spirit and has Christ himself within it.… Christ promises nothing less than that he will be present and will help those who believe on him through the Spirit, even though he ascends into the heavens after his resurrection from the dead.

By love, and the observance of His commandments, that will be perfected in us which He has begun, viz. that we should be in Him, and He in us.

AS if He said, Though I shall die, I shall rise again. And ye shall live also, i. e. when ye see Me risen again, ye will rejoice, and be as dead men brought to life again.

As if He said, Ye think that by sorrowing, as ye do, for my death ye prove your affection; but I esteem the keeping of My commandments the evidence of love. And then He shows the privileged state of one who loves: And he that loveth Me shall be loved of My Father, and I will love him.

Or, as after the resurrection He was to appear to them in a body more assimilated to His divinity, that they might not take Him then for a spirit, or a phantom, He tells them now beforehand not to have misgivings upon seeing Him, but to remember that He shows Himself to them as a reward for their keeping His commandments; and that therefore they are bound ever to keep them, that they may ever enjoy the sight of Him.

Because I live, you shall live also.

The world, that is, all the other people, sees me for a short time only, but you will see me again after my resurrection so that this vision of yours may testify that I am living again. And you will not only see me living, but the same thing will happen to you. When you also resurrect at the right time after your death, you will live and will participate in a second life. He does not say, “because I live” casually, that is, you will see me because I live. But he means You will witness the fact that I am alive, and by seeing it you will know that I resurrected from the dead and live and that I did not remain subject to death, as many believe.

[AD 444] Cyril of Alexandria on John 14:19
Now that the Passion is close at hand, and brings along with it the moment of His Assumption, He says that He will be invisible to the world, that is, to them that value the enjoyment of things temporal before the Divine blessings, and set more store by earthly things than by heavenly. And by way of making our belief to the end thereof kindred and consistent with what has been already said above, we shall be right in saying, that God the Father has given the Paraclete, i.e. the Holy Spirit, of course through the Son; for all things are through Him from the Father. Notwithstanding He has come, not on all indiscriminately, both evil and good, but on them on whom it was fitting He should go forth. For so far forth as touches the most rich and unstinted grace of the Giver, no man of all in the earth remained a non-partaker: For I will pour out, He says in the prophets, of my Spirit on all flesh. Yet each man is unto himself an accessory cause of his possessing or else wholly failing to get the God-given blessing. For some men, because that in no wise do they strive to cleanse their own mind by all goodness, but love exceedingly to dwell in the evils in the world, shall abide non-partakers of the Divine grace, and shall not see Christ in themselves, forasmuch as they have a heart void of the Spirit. For this cause albeit they are ranged on the side of the Protector of the orphans they are torn in pieces by simply everything that is strong enough to overreach, be it a passion or a devil, or yet any other worldly lust, and by everything that can drag them down as it were and overpower them unto sin. Howbeit, unto the holy and them that were purposed to receive Him, He said, as was likely He would, forasmuch as they were going to endure none of those ills, I will not leave you orphans, I am coming unto you. And so He says He shall be invisible and wholly unbeheld by them that mind the hings in the world, after His Departure hence, I mean His Ascension into heaven. But He says He will be found visible unto the holy, forasmuch as the Holy Spirit is putting a certain Divine and spiritual flash in the eyes of their heart, and sowing therein all good knowledge.

For we shall either suppose that this is what He means by Yet a little while and the world beholdeth Me no more; but ye behold Me; or else turning aside to a different point of view----especially when there is intertwined with His words the saying Because I live, ye shall live also----we reason somewhat on this wise. For after His Revival from the dead, when He had effected for our nature the return unto that whereunto it existed from the beginning, and had made man incorruptible, He ascended, as it were by way of first-fruits and in the Temple of His own Body first, unto God the Father in heaven. But after in the meanwhile accomplishing a short time, He will descend again, as we believe, and will return again unto us, in the glory of His Father with the Holy Angels, and will set up the appalling tribunal before all men, both evil and good. For all created things shall come to judgment. And rendering becoming awards, corresponding to the life each one has led, He will say to them on the left, i.e. to those that have minded the things in the world: Depart from Me ye cursed, into the eternal fire prepared for the devil and his angels; howbeit to them on the right, i.e. to the holy and good: Come ye blessed of My Father, inherit the kingdom prepared for you from the foundation of the world. For they shall be with Christ and shall reign with Him, and shall revel in the heavenly blessings, having been made conformable to His Resurrection, and escaped the meshes of the ancient corruption, being endued with the long and ineffable life, and living endlessly with the ever-living Lord. For that they who have practised a life dear to God and exalted, shall be with Christ without ceasing, to wit contemplating His divine and unspeakable beauty, Paul will make clear where he says: For the Lord Himself shall descend from Heaven, with a shout, with the voice of the archangel, and with the trump of God: and the dead in Christ shall rise first: then we that are alive, that are left, shall together with them be caught up in the clouds, to meet the Lord in the air: and so shall we ever be with the Lord; and again, to them that have chosen to mortify worldly passions: For ye died, and your life is hid with Christ in God. When Christ, Who is our life, shall be manifested, then shall ye also with Him be manifested in glory. So----for I will sum up the meaning of the Lord's saying----the lovers of the evil things in the world shall go down to Hades and be banished from the presence of Christ; howbeit there shall be with Him and dwell with Him for ever the lovers of virtue, they who have kept inviolate the earnest of the Spirit, and being with Him of a surety they shall also behold His Divine Beauty without all hindrance. For, he says, the Lord shall be thine eternal Light, and God thy glory. And it is also likely that this is what the Lord means to make manifest, when we hear Him saying: Yet a little while and the world beholdeth Me no more; but ye behold Me; because I live ye shall live also. Howbeit in no wise will He speak falsely in saying that the time intervening, before His Revelation as it were, is a little while. For to God Who always is, even what is a long time with us counts utterly for nothing; and the Psalmist will testify this when he says: For a thousand years in Thy sight, O Lord, are but as yesterday that is past, and a watch in the night.
[AD 444] Cyril of Alexandria on John 14:19
Those who love evil in the world will go down to Hades and be banished from the presence of Christ. However, the lovers of virtue who have kept inviolate the earnest of the Spirit will be with him and dwell with him. And being with him surely they shall also behold his divine beauty without any hindrance. For he says, “the Lord shall be your eternal light and God shall be your glory.”

If he wished to indicate a mere unity of will, why did he set forth a kind of gradation and sequence in the completion of the unity, unless it were that, since he was in the Father through the nature of deity and we on the contrary are in him through his birth in the body, he would have us believe that he is in us through the mystery of the sacraments? And thus there might be taught a perfect unity through a mediator while, we abiding in him, he abode in the Father and as abiding in the Father abode also in us. In this way we might arrive at unity with the Father, since in him who dwells naturally in the Father by birth, we also dwell naturally while he himself abides naturally in us also.

[AD 407] John Chrysostom on John 14:20
With regard to the Father, these words refer to Essence; with regard to the disciples, to agreement of mind and help from God. And how, tell me, is this reasonable? says some one. And how, pray, is the contrary reasonable? For great and altogether boundless is the interval between Christ and the disciples. And if the same words are employed, marvel not; for the Scripture is often wont to use in different senses the same words, when applied to God and to men. Thus we are called gods, and sons of God, yet the word has not the same force when applied to us and to God. And the Son is called Image, and Glory; so are we, but great is the interval between us. Again, You are Christ's, and Christ is God's 1 Corinthians 3:23, but not in like manner as Christ is God's are we Christ's. But what is it that He says? When I am arisen, He says, -->you shall know that I am not separated from the Father, but have the same power with Him, and that I am with you continually, when facts proclaim the aid which comes to you from Me, when your enemies are kept down, and you speak boldly, when dangers are removed from your path, when the preaching of the Gospel flourishes day by day, when all yield and give ground to the word of true religion. As the Father has sent Me, so send I you. John 20:21 Do you see that here also the word has not the same force? For if we take it as though it had, the Apostles will differ in nothing from Christ. But why says He, Then you shall know? Because then they saw Him risen and conversing with them, then they learned the exact faith; for great was the power of the Spirit, which taught them all things.
[AD 428] Theodore of Mopsuestia on John 14:20
Then, he says, from these facts only you will learn that what I said to you was true about which you now have your doubts. I said, “I am in my Father” concerning the equality of nature and the inseparable connection when I will appear so. And I said “you are in me” concerning your faith and love for me when you will be made a participant with me in charity and also in the gift of the Spirit. “And I in you” is said with reference to what the close connection will cause when, after being regenerated by the power of the Spirit, you are with me in the body and I am with you in the head.

[AD 444] Cyril of Alexandria on John 14:20
The meaning of the passage before us is somewhat hard to reach, and as it were demands that the inquiry applied to it be keen, and imposes very considerable delay on our discourse: howbeit we believe that Christ will once more direct us into truth. Now some, albeit among the number of those once supposed among the impious heretics to be of eminence, refusing malignantly to confess that the Son is of the essence of God the Father, and is therefore in Him, conceive that the union is an accidental one and not one of nature; and in fact they have written----belching forth thereby what proceeds from their own minds, not from the Holy Spirit----that, forasmuch as the Son is loved by the Father, and Himself loves the Father in return, it is after this sort that He is in Him. And these demented men bring as a proof hard to overthrow, the words attached to the clause before us, to wit concerning us and Him; and indeed they say, resting withal their blasphemies on the staff of a reed, that as we are said to be in Him, and have Him in ourselves, and are not united to Him in the matter of our essence, but the manner of the union is determined by our capacity to love and be loved in return; so the Son also, one of them would say, is not at all within the essence of God the Father, but being wholly distinct in the matter of His nature, and being quite differently characterised, is understood to be in the Father solely by virtue of the law of love. For it is their aim, as we said just now, to show that the Only-begotten is an effect and a creature, and produced and honoured merely with His preeminence over the rest of the creatures, notwithstanding He is external to the essence of God the Father.

But forasmuch as concerning this we have already spoken at length, assaying thereby to show to the best of our power, that the Son is by nature in the Father and that the union which He has with Him is substantial, we will forbear further for the present to extend our remarks touching this subject. Howbeit we will not wholly leave as it were the ground of the argument clear for our opponents to overrun, but will set the battle in array against them in a few words, exhibiting so far as possible at once the mischief and the ignorance of their wicked and loathsome artifice; and particularly we will say: If it is solely by reason that He is loved and loves that the Son is in the Father, and if by the same law we are in Him and He in us, and no different bond of union is discernible, whether we consider that which binds the Son to the Father, or us to Him and Him to us: in what sense or on what principle, I pray you, does He say that it is in that day we shall know the mystery of this? For seemingly we do not yet know that the Father loves the Son, and the Son also loves the Father; nor, I suppose, do we yet know our own condition, but a vain calculation mocks us, when we think that the Son loved us, and for this cause won us unto the Father, and that we also loved Him! For when He says In that day ye shall know, He shows that the time of the knowledge is not yet present; then, why did the Lord all in vain make our ears ring with His words: The Father loveth the Son? For that He Himself loves the Father, who will deny? And how, I pray you, said He also that His choosing to suffer in our behalf was a clear proof of His love to us-ward? For greater love hath no man than this, He says, that a man lay down His life for His friends. And why did He manifestly seek for love from us towards Himself, and that for this cause we should be eager to fulfil His good pleasure? For he that loveth Me, He says, will keep My commandments. For when shall we keep the Divine commandment, if at the present we make no account thereof? Forasmuch then as it is fit we believe that the Son loves the Father, and loves us and is beloved by us, how is it not consistent to conceive that the Son has purposed to signify something diverse from this, and not to define the manner of the union by the law of love; or rather that He has manifestly introduced it to us as after some different sort, when He says: In that day ye shall know that I am in My Father and ye in Me and I in you. But peradventure the opponent will answer, that before the Passion Christ said such things as these to us, to wit that He loves the Father and is loved again by the Father, and He loves us also and we Him; but that after the Passion and the Revival from the dead, when we saw that He burst the bonds of death, we learnt that He is in the Father, forasmuch as also He is loved, and for this cause rose from the dead. For this cause also He is in us and we in Him, according to the same law of love.

But we reply: Your opposition is exceeding idle, and wholly without understanding, and a tissue of rotten words. But, excellent Sirs, consider once more that what we knew of a truth before the Resurrection from the dead, there was no need to learn after the Resurrection. For if it was only imperfectly that we believed that the Son is loved of His own Father, and Himself loves the Father, it was indeed necessary to await the Resurrection, with intent we might therefrom have the perfection of knowledge. But if the Father be worthy of belief when He says even before the Resurrection: He is My beloved Son; and if the Saviour Himself also speaks true when He says: The Father loveth the Son; and if the law of love is fittingly to be conceived in its entire perfection; why do ye foolishly strike at us with hard words? And why, thrusting aside the beauty of the Truth, do ye fashion you an unsightly lie, dragging outside of the Father's essence the Son that is of Him and through Him, and withal inventing right rotten words, and contriving tricks of absurd argumentation? For that the Only-begotten loved us, and that we also loved Him, will be open to any one to see with utmost readiness, so he be willing to regard intently the nature of the truth: For being in the form of God the Father, He counted it not a prize to be on an equality with God, but emptied Himself, taking the form of a servant. Then what, I pray you, was the ground of such actions? Was it not the law of love towards us? And how is it possible to doubt? And our willingness too on behalf of Christ and readiness to abandon our very life to the persecutors, that we may not deny our own Lord, will it not supply proof to demonstration of our love to Him? But a man will also say that this either is entirely true, or will condemn the Holy Martyrs as having wrought a desperate struggle for Christ for no useful end, and endured so grievous a danger all unrecompensed. So then, whereas it is proved with all clearness that the Father has towards the Son love in perfection, and that in like sort also He loves the Father, and we Him and He us, what reason could there be in supposing that the discernment thereof is referred perchance to other times, when the Lord says: In that day ye shall know that I am in the Father, and ye in Me, and I in you.

For away with their idle talkings and the pretentiousness of their God-hating speculations! But we waxing bold in the consciousness of bearing the torch of the Spirit, will not hesitate to say what seems to be right, with intent to clear up the questions at issue. So then, having said above: Because I live ye shall live also, straightway He is found to have added: In that day ye shall know that I am in My Father, and ye in Me, and I in you. Then to what man, upright and wont to think rightly, would it not be abundantly clear, that He limits a day, the time to wit of the knowledge hereof, upon which we ourselves also, renovated after His likeness, shall ascend unto eternal life, escaping from the curse of death? And something after this sort the Christ-bearer seems to me to indicate----I mean, Paul----when, revealing to us the Divine Mystery, he writes to some: For ye died and your life is hid with Christ in God; when then Christ, which is your life, shall appear, then shall ye also appear with Him in glory. For He shall transform the body of our humiliation----this body assuredly, and not a diverse----to be conformable unto His glory, and shall transmute the nature of man unto the ancient type with power unspeakable, changing all things easily unto whatsoever He will, none forbidding; for He is very God That maketh all things and changeth the fashion of them, as it is written. So then at that day, or time, when ye also yourselves shall live----for I do live, albeit made man like unto you, and clad with the body which as touching its proper nature is subject to corruption----ye shall recognise clearly, He says, that I am in the Father, and ye in Me, and I in you. And we shall be disposed to think that the Lord said this unto us, not with intent we might suppose that He is in the Father according to the law of love, as indeed our opponents thought fit to believe, but according to the power of a deep mystery, which is also both difficult to conceive, and hard to utter; howbeit I will essay how I may be able to expound it.

Now I hold that the mind of any man on earth is very far from equal to the accurate exposition hereof; notwithstanding, in the fervour of love, albeit with powers of sight and utterance but little whetted, let us now consider the aim of the Incarnation of the Only-begotten. Let us, I pray you, examine the cause, wherefore, being as God in the form of God the Father, He counted it not a prize to be on an equality with God, but emptied Himself, taking the form of a servant, and endured the cross despising the shame. For in this way the depth of the mysteries before us will be manifest, so far as is possible, howbeit hardly so. But we shall learn how the Son is in the Father, naturally, that is, and not by virtue of the relation of being loved and loving as invented by our opponents; and we again in Him after the same sort, and He in us. Well then, one cause the wise Paul expounded was a true and most general cause of the Incarnation of the Only-begotten, when he said: For God the Father was pleased to gather together in one all things in Christ; and "gathering in one," both the name and the thing, plainly involves the bringing back again and resumption of the things that have digressed to an unconformable end unto what they were in the beginning. Then desiring to put before us in a clear light the methods of the gathering in detail, at one time he said: For what the Law could not do, in that it was weak through the flesh, God, sending His own Son in the likeness of sinful flesh and as an offering for sin, condemned sin in the flesh: that the ordinance of the Law might be fulfilled in us, who walk not after the flesh, but after the Spirit; and at another again: Since then the children are sharers in flesh and blood, He also Himself in like manner partook of the same; that through death He might bring to nought him that had the power of death, that is the devil; and might deliver all them who through fear of death were all their lifetime subject to bondage. And herein we have two methods of the gathering together which Paul expounded the doctrine of the Incarnation of the Only-begotten as of necessity involving; but a further method, inclusive of the others, was set forth by the wise Evangelist John. For he writes thus touching Christ: He came unto His own, and they that were His own received Him not. But as many as received Him, to them gave He the right to become children of God, even to them that believe on His Name: which were born not of blood, nor of the will of the flesh, nor of the will of man, but of God. So then it is abundantly evident and manifest I conceive unto all, that it was for these causes especially that, being by nature God and of God, the Only-begotten has become man; namely with intent to condemn sin in the flesh, and by His own Death to slay Death, and to make us Sons of God, regenerating in the Spirit them that are on earth unto supernatural dignity. For it was, I trow, exceeding good, after this sort to gather together again into one and to recover unto the ancient estate the sore-stumbled race, to wit, the human. Again, let us set each of the causes just given side by side with the Lord's saying, and thereupon make such remarks that seem fit. For we must inquire in what sense it may be seemly to conceive that God the Father condemned sin in the flesh by sending His own Son in likeness of sinful flesh. For albeit the Son were by nature God and had shone forth from His essence and possessed naturally the immutability of His proper being, and for this cause in no wise could stumble into sin, or turn aside anywhither into what is not right, the Father caused him voluntarily to descend into the flesh that is subject to sin, with intent that making very flesh His own, He might bring it over unto His own natural property, to wit, sinlessness. For, I conceive, we shall not be right in believing that it was with intent to effect this for the Temple of His own Body alone that the Only-begotten has been made man; for where were the glory and profit of His Advent unto us to be seen, if He accomplished the salvation of His own Body alone? But we believe rather that it was to secure the benefits for all nature through Himself and in Himself first as in the firstfruits of humanity, that the Only-begotten has become like us. For like as we have followed after not only death but all the sufferings of the flesh, undergoing this suffering in the first man by reason as well of the transgression as of the divine curse; after the same sort, I conceive, shall we all of us follow Christ, as He saves in many ways and sanctifies the nature of the flesh in Himself. Wherefore also Paul said: And as we love the image of the earthy, we shall bear also the image of the heavenly. For the image of the earthy, to wit of Adam, is to be in sufferings and corruption; and the image of the heavenly, to wit of Christ, is to be in impassibility and incorruption. So then the Word being God by nature condemned sin in His own flesh, by charging it to cease its activity, or rather so amending it as that it should move after the good pleasure of God, and no longer at its own will; and so whereas the body was natural, He made it spiritual. This then is one method of the gathering together; but the method that is most befitting and appropriate to the drift of the passage before us shall follow it. And it will be our task to speak touching eternal life and the slaying of Death, and how the Only-begotten removed from human nature the corruption that came of the transgression. Therefore forasmuch as the children are partakers of blood and flesh, He also in like manner took part in the same with intent to slay Death, and that He that created all things unto immortality and made the generations of the world healthful, according as it is written, might remould once more the fashion of things unto their ancient estate.

And once again, albeit my argument be more minute than behoves, yet, as it needs must, it shall proceed, setting forth the ancient condition of our estate. For I conceive the sincere purpose to grasp the meaning of the words before us, will wholly escape the dangers that come of mere loitering. So then this rational creature upon earth, I mean man, was made from the beginning after the image of Him that created him, according to the Scriptures; and the meaning of image is various. For an image may be, not after one sort, but after many; howbeit the element of the likeness to God that made him, which is far the most manifest of all, was his incorruptibility and indestructibility. But never, I conceive, would the creature have been sufficient unto himself to be so, merely by virtue of the law of his own nature; for how could he that is of the earth in his own nature have been shown to possess the glory of incorruption, unless it were from the God that is by nature both incorruptible and indestructible and ever the same, that he was enriched with this boon in like manner as with all others? For what hast thou that thou didst not receive? saith somewhere unto us the inspired Paul, with exceeding reason and truth. With intent then that what was once brought into being out of that which is not, might not, by sinking back to its own original, once more vanish into nothing, but rather be preserved evermore----for this was the aim of Him that created it----God makes it partaker of His own nature. For He breathed into his face the breath of life, i.e. the Spirit of the Son, for He is Himself the Life with the Father, holding all things together in being. For the things that are receptive of life both move in Him and live, according to the words of Paul.

And let none of us found hereupon any words of false teaching, by supposing that we said that the Divine inbreathing has become a soul unto the living creature; for this we deny, guided unto the truth of the matter by such reasoning as this. If any suppose that the Divine inbreathing became a soul, let him tell us whether it was turned aside from its own nature and has been made into a soul, or has it remained in its own identity? For if they say it has been on anywise changed and that it traversed the law of its own nature, they will be convicted of blasphemy; for they will say that the immutable and ever-unchanging Nature is altogether mutable; whereas if it was in no wise turned aside, but has ever remained what it always was, after coming forth from God, to wit His inbreathing, how did it deflect unto sin, and become susceptible of so great diversity of passions? For, I trow, they would not say that there is, in anywise, in the Divine Nature the possibility of transgression. But to get over the words due to the subject before us without using lengthy proofs, I say we must repeat this once again and say,----that no one, I imagine, rightly minded would suppose that the Breath which proceeded from the Divine Essence became the creature's soul, but that after the creature was ensouled, or rather had attained unto the propriety of its perfect nature by means of both, soul and body to wit, then like a stamp of His own Nature the Creator impressed on it the Holy Spirit, i. e. the Breath of Life, whereby it became moulded unto the archetypal Beauty, and completed after the image of Him that created it, enabled unto every form of excellence, by virtue of the Spirit given to dwell in it. But whereas, being free of will, and entrusted with the reins of its own purposes----for this also is an element in the image, forasmuch as God has power over His own purposes----it turned and has fallen----but how this came to pass the Holy Scripture must teach you, for the account of it therein is plain----God the Father both determined and took in hand to gather together once more in Christ the nature of man unto its ancient estate, and willing it accomplished it withal. So then it naturally follows that we should observe how it has come to pass. It was not otherwise possible for man, forasmuch as he was of a nature that was perishing, to escape death, save by recovering that ancient grace, and partaking once more in God Who holdeth all things together in being and preserveth them in life through the Son in the Spirit. Therefore He hath become partaker of blood and flesh, i.e. He hath become man, being by nature Life, and begotten of the Life that is by nature, i.e. of God the Father----to wit, His Only-begotten Word, with intent that ineffably and inexpressibly and as He alone could skill to do, uniting Himself with the flesh that by the law of its own nature was perishing, He might bring it back unto His own Life and make it through Himself partaker of God the Father. For He is Mediator between God and men, according as it is written, knit unto God the Father naturally as God and of Him, and again unto men as man; and withal having in Himself the Father and being Himself in the Father; for He is the impress and effulgence of His Person, and not distinct from the Essence, whereof He is impress and wherefrom He proceeds as effulgence; but both being Himself in It, and having It in Himself; and again having us in Himself according as He wears our nature and our body has become entitled the Body of the Word. For the Word was made flesh, according to the utterance of John. And He wears our nature, remoulding it unto His own Life. And He is also Himself in us; for we have all been made partakers of Him, and have Him in ourselves through the Spirit; for, for this cause we have Both, being made partakers of the Divine Nature, and are entitled sons, after this sort having in us also the Father Himself through the Son. And Paul will testify hereof where he says: Because ye are sons God sent forth the Spirit of His Son into your hearts, crying, Abba, Father. For His Spirit is not something diverse from the Son, I mean as touching the law of identity, to wit, identity of nature.

This being the result of the progress of our discourse of these things, let us now take the meaning of what has been set forth, and adapt it to the interpretation of our Saviour's words: For in that day ye shall know, He says, that I am in the Father, and ye in Me, and I in you. For I live Myself, He says, for I am Life by nature, and have shown the Temple of My own Body alive; but when ye also yourselves, albeit ye are of a corruptible nature, shall behold yourselves living in like manner as I do, then indeed ye shall know exceeding clearly, that I, being Life by nature, did knit you through Myself unto God the Father, Who is also Himself by nature Life, making you partakers as it were and sharers in His Incorruption. For naturally am I in the Father----for I am the Fruit of His Essence and Its real Offspring, subsisting in It, having shone forth from It, Life of Life----and ye are in Me and I in you, forasmuch as I appeared as a man Myself, and made you partakers of the Divine Nature by putting My Spirit to dwell in you. For Christ is in us through the Spirit, converting that which has a natural tendency to corruption into incorruption, and transferring it from the condition of dying unto that which is otherwise. Wherefore also Paul says that He that raised Jesus Christ from the dead, shall quicken also your mortal bodies, through His Spirit that dwelleth in you. For albeit the Holy Spirit proceeds from the Father, yet He comes through the Son, and is His Own; for all things are through the Son from the Father. For that it was through the Spirit we were wrought anew unto eternal life, the Divine Psalmist will bear us record, when he cries as unto the God of all: When Thou openest Thine Hand, all things shall be filled with goodness; when Thou turnest away Thy Face they shall be troubled; Thou shalt take away their breath and they shall fail and shall turn again to their dust. Thou shalt send forth Thy Spirit and they shall be made, and Thou shalt renew the face of the earth. Hearest thou how the transgression that was in Adam, and the "turning away" as it were from the Divine precepts, sore troubled the nature of man, and made it return to its own earth? But when God sent forth His Spirit, and made us partakers of His own Nature, and through Him renewed the face of the earth, we were transfigured unto newness of life, casting off the corruption that comes of sin, and once more grasping eternal life, through the grace and love towards mankind of our Lord Jesus Christ, through Whom and with Whom unto God the Father, be glory with the Holy Spirit unto the ages. Amen.
[AD 444] Cyril of Alexandria on John 14:20
If it is merely because he loves and is loved that the Son is in God the Father, and if by the same law we are in the Son and he in us, and no different bond of union is discernible—whether we consider that which binds the Son to the Father or us to him and him to us—then in what sense, or on what principle, I ask you, does Jesus say that “in that day” we shall know the mystery of this?…“For in that day you shall know,” he says, “that I am in the Father, and you are in me, and I am in you.” For I myself live, he says, for I am life by nature and have shown the temple of my own body alive. But when you yourselves (albeit you are of a corruptible nature) also behold yourselves living in a similar way as I do, then indeed you shall know very clearly that I, being life by nature, knitted you through myself into God the Father, who is also himself life by nature, making you partakers as it were and sharers in his incorruption. For I am in the Father naturally, being the fruit of his essence and its real offspring, subsisting in it, having shone forth from it. I am life of life, and you are in me and I in you, forasmuch as I appeared as a man myself and made you partakers of the divine nature by having my Spirit dwell in you. For Christ is in us through the Spirit, converting that which has a natural tendency to corruption into incorruption and transferring it from the condition of dying to that which is otherwise. And so Paul also says that “he who raised Jesus Christ from the dead shall enliven also your mortal bodies through his Spirit that dwells in you.” For albeit the Holy Spirit proceeds from the Father, yet he comes through the Son and is his own. For all things are through the Son from the Father. The divine psalmist will testify that it was through the Spirit that we were recreated for eternal life when he cries as one speaking to the God of all …, “You shall take away their breath and they shall fail and shall turn again to their dust. You shall send forth your Spirit, and they shall be made, and you shall renew the face of the earth. Do you hear how the transgression that was in Adam and the “turning away” from the divine commandments, troubled the nature of humanity and made it return to its own earth? But when God sent forth his Spirit and made us partakers of his own nature and through him renewed the face of the earth, we were transfigured to “newness of life,” casting off the corruption that comes with sin and once more grasping eternal life through the grace and love toward the human race that our Lord Jesus Christ has.

[AD 407] John Chrysostom on John 14:21
It is not enough merely to have them, we need also an exact keeping of them. But why does He frequently say the same thing to them? As, If you love Me, you will keep My commandments John 14:15; and, He that has My commandments and keeps them; and, If any one hears My word and keeps it, he it is that loves Me— he that hears not My words, loves Me not. John 14:24 I think that He alluded to their despondency; for since He had uttered many wise sayings to them concerning death, saying, He that hates his life in this world shall save it unto life eternal John 12:25; and, Unless a man take his cross and follow Me, he is not worthy of Me Matthew 10:38; and is about to say other things besides, rebuking them, He says, Think ye that you suffer sorrow from love? The not sorrowing would be a sign of love. And because He wished all along to establish this, as He went on He summed up His discourse in this same point; If you loved Me, He says, ye would have rejoiced, because— I go to My Father John 14:28, but now you are in this state through cowardice. To be thus disposed towards death is not for those who remember My commandments; for you ought to be crucified, if you truly loved Me, for My word exhorts you not to be afraid of those that kill the body. Those that are such both the Father loves and I. -->And I will manifest Myself unto him. Then says Judas,
[AD 428] Theodore of Mopsuestia on John 14:21
Whoever loves me and keeps my commandments will enjoy my love and that of the Father and will obtain in addition a vision of who I really am. They will not be disadvantaged by the fact that they did not see me in body. Indeed, they will also enjoy that vision at the appropriate time as well when they see me coming down from heaven.

[AD 430] Marcus Eremita on John 14:21
Do you see how [Jesus] has hidden his manifestation in the commandments? Of all the commandments, therefore, the most comprehensive is to love God and our neighbor. This love is made firm through abstaining from material things and through stillness of thoughts.Knowing this, the Lord enjoins us “not to be anxious about tomorrow,” and rightly so. For if someone has not freed himself from material things and from concern about them, how can he be freed from evil thoughts? And if he is beset by evil thoughts, how can he see the reality of the sin concealed behind them? This sin wraps the soul in darkness and obscurity and increases its hold on us through our evil thoughts and actions. The devil initiates the whole process by testing a person with a provocation that the person is not compelled to accept. But the one urged on by self-indulgence and self-esteem begins to entertain this provocation with enjoyment. Even if their discrimination tells them to reject it, yet in practice they take pleasure in it and accept it. If someone has not perceived this general process of sinning, when will he pray about it and be cleansed from it? And if he has not been cleansed, how will he find purity of nature? And if he has not found this, how will he behold the inner dwelling place of Christ? For we are a dwelling place of God, according to the words of prophet, evangelist and apostle.

[AD 444] Cyril of Alexandria on John 14:21
Our Saviour here says that the revelation of the mystery in us will then be clearest when we see ourselves living in conformity with His likeness. For as I live, He says, ye shall live also; the mind of each being fulfilled as it were not with what he has heard and believed merely, but rather with what he actually enjoys, when he has reached the completion of the promise. For experience is more powerful than language in ability to convince and satisfy. That we may not think that all without distinction are endowed with the power to partake of so holy a blessing, even though they be not good men and illuminated by the fear of God, He has added at once to His speech the qualification, "they that love Me;" clearly showing thereby that no others will be allowed to choose so incomparable a grace, but those who have chosen to live most righteously: for they would be "those that love Him." For even if it be the fact that Christ raises the bodies of all men, for there will be a resurrection of the evil and the good alike, yet not to all without distinction will a new life of glory and felicity be given. For it is clear that some only rise again to punishment, and will have a life more grievous than any death, while others spending ages of blessedness, will actually live the desirable and holy life in Christ. For that they who are doomed to receive the sentence of punishment from Christ on the occasion of the judgment, will abide without a taste of the blessed life, although they shared with the Saints the lot of resurrection, He makes plain by these words: He that believeth on the Son hath eternal life, but he that obeyeth not the Son shall not see life, but the wrath of God shall abide on Him. For know that although while all the evil and the good alike await the resurrection, He says that those who are fast bound by the charge of disobedience cannot even attain to a glimpse of the life, as He declares that it is not the mere act of resurrection that is life, but that that life rather consists in rest and glory and felicity, spiritual of course and of no other kind. A spiritual kind of felicity is meant, the perfect knowledge of God and the complete revelation of the mysteries of Christ, not as in a glass and in riddles, even as now showing the characters of the object of our quest dimly, but shining out to us and glistening in perfect purity and making our knowledge quite complete. For that which is in part shall be done away, as Paul says.

Our Lord Jesus Christ then, when He teaches us that to those who choose to love Him and to those who do His commandments is the promise of His revelation given, and to them it is more appropriate and pertinent, and not to those who are otherwise minded and who do the contrary, has conveyed this useful lesson in the words: He that hath My commandments and keepeth them, he it is that loveth Me. And a man has His commands when he has received the faith, and, laying it to heart, has let into his inmost soul the unpolluted and unmistakeable teaching of the Gospel commandments. And he fulfils them by carrying them out into actuality, and by making haste to distinguish himself by the light of his actions. Such a man then is perfect and wholly wedded to righteousness, a shining light by his faith and conduct, who has witness borne him of his holiness after the pattern of Christ. For At the mouth of two or three witnesses shall every word be established, according to the Scripture. A man of this sort again, God the Father will surely love, and no less also the Son will love him. For as He is of the same Substance, so also has He the same Will as His Father. For as the Substance is one the Will also is one, and there is one purpose over all, and there is no discord severing Their Wills in twain. For to those who are thought worthy of the Divine love He promises that He will give a glorious reward and that He will crown them with exceeding great blessings. For I will manifest Myself unto him, He says. For to the pure in heart the mystery of the Godhead will be clearly revealed, and Christ gives them light, illuminating the path of every duty by His Spirit, and unveiling Himself and making Himself visible as it were by the ineffable torchlight of the soul. And those who have made their choice once for all are blessed and worthy of all admiration. And methinks the prophet David was a man after this sort when he says, I will hear what the Lord God will say in me. And so is also the Divine Apostle when he exhorts us, saying, If ye seek a proof of Christ that speaketh in me; for He speaks of things concerning Himself in His Saints by His Spirit; yea, reveals other mysteries besides. Therefore it is true that knowing these things well, the Saints sometimes say, Unto us God revealed them through the Spirit; sometimes, But we have the mind of Christ, meaning by His mind His Spirit.
[AD 444] Cyril of Alexandria on John 14:21
Jesus has added the qualification “he who loves me,” clearly showing that none other than those who have chosen to live most righteously will be allowed to choose such an incomparable grace, for they are the ones who love him. While it is true that Christ raises the bodies of all—for there will be a resurrection of the evil and the good alike—a new life of glory and happiness will not be given to all without distinction. For it is clear that some only rise again to punishment and will have a life worse than any death, while others … will live a desirable and holy life in Christ.

Even now the Son loves those who love him and the Father. But he loves them now so that they may live properly as a result of their faith, which works through love. Then (in the future), he will love them as well, but in such a way that they may come to the vision of the truth of which they only had a taste through faith. When he adds, “I will show myself to him,” he will indeed show himself to all human beings but will show his very own being only to the elect.

For by this he testified that while the Spirit of Christ abides in us the Spirit of God abides in us. The Spirit of him who was raised from the dead is no different from the Spirit of him who raised him from the dead. For they come and dwell in us. I ask whether they will come as strangers associated together and make their abode or in unity of nature? No, the teacher of the Gentiles contends that it is not two spirits—the spirits of God and of Christ—that are present in those who believe but the Spirit of Christ, which is also the Spirit of God. This is no joint indwelling; it is one indwelling, yet an indwelling under the mysterious semblance of a joint indwelling. For it is not the case that two spirits indwell, nor is one that indwells different from the other. For there is in us the Spirit of God and there is also in us the Spirit of Christ, and when the Spirit of Christ is in us there is also in us the Spirit of God. And so, since what is of God is also of Christ, and what is of Christ is also of God, Christ cannot be anything different from what God is. Christ, therefore, is God, one Spirit with God.

[AD 398] Didymus the Blind on John 14:22-27
(Didym. de Spir. Sancto, l. ii. inter opera Hieron.) The Saviour affirms that the Holy Spirit is sent by the Father, in His, the Saviour's, name; which name is the Son. Here an agreement of nature and propriety1, so to speak, of persons is shewn. The Son can come in the Father's name only, consistently with the proper1 relationship of the Son to the Father, and the Father to the Son. No one else comes in the name of the Father, but in the name of God, of the Lord, of the Almighty, and the like. As servants who come in the name of their Lord, do so as being the servants of that Lord, so the Son who comes in the name of the Father, bears that name as being the acknowledged only-begotten Son of the Father. That the Holy Spirit then is sent in the Son's name, by the Father, shows that He is in unity with the Son: whence He is said too to be the Spirit of the Son, and to make those sons by adoption, who are willing to receive Him. The Holy Spirit then, Who cometh in the name of the Son from the Father, shall teach them, who are established in the faith of Christ, all things; all things which are spiritual, both the understanding of truth, and the sacrament of wisdom. But He will teach not like those who have acquired an art or knowledge by study and industry, but as being the very art, doctrine, knowledge itself. As being this Himself, the Spirit of truth will impart the knowledge of divine things to the mind.

(Hom. lxxv. 1, 2) Or thus: Judas thought that he should see Him, as we see the dead in sleep: How is it, that Thou wilt manifest Thyself unto us, and not unto the world? meaning, Alas, as Thou art to die, Thou wilt appear to us but as one dead. To correct this mistake, He says, I and My Father will come to him, i. e. I shall manifest Myself, even as My Father manifests Himself. And will make our abode with Him; which is not like a dream. It follows, And the word which ye hear is not Mine, but the Father's which sent Me; i. e. He that heareth not My words, inasmuch as he loveth not Me, so loveth he not My Father. This He says to show that He spoke nothing which was not the Father's, nothing beside what seemed good to the Father.

(Hom. lxxv. 3) These things have I spoken unto you, being yet present with you. Some of these things were obscure, and not understood by the disciples.

(Hom. lxxv. 3) To enable them to sustain His bodily departure more cheerfully, He promises that that departure shall be the source of great benefit; for that while He was then in the body, they could never know much, because the Spirit would not have come: But the Comforter, which is the Holy Ghost, Whom the Father will send in My name, He shall teach you all things, and bring all things to your remembrance, whatsoever I have said unto you.

(Hom. lxxv. 3) He often calls Him the Comforter, in allusion to the affliction in which they then were.

(Hom. lxxiv. 3) Peace I leave with you, My peace I give unto you: He says this to console His disciples, who were now troubled at the prospect of the hatred and opposition which awaited them after His departure.

(Hom. lxxv. 3) External peace is often even hurtful, rather than profitable to those who enjoy it.

[AD 430] Augustine of Hippo on John 14:22-27
(Tract. lxxvi. 1) Our Lord having said, A little while, and the world seeth Me no more: but ye shall see Me: Judas, not the traitor named Scariot, but he whose Epistle is read among the Canonical Scriptures, asks His meaning: Judas saith unto Him, not Iscariot, Lord, how is it that Thou wilt manifest Thyself unto us, and not unto the world? Our Lord in reply explains why He manifests Himself to His own, and not to aliens, viz. because the one love Him, the other do not. Jesus answered and said unto him, If a man love Me, he will keep My words.

(Tract. lxxvi. 2) Love distinguishes the saints from the world: it maketh men to be of one mind in an house; in which house the Father and the Son take their abode; who give that love to those, to whom in the end they will manifest themselves. For there is a certain inner manifestation of God, unknown to the ungodly, to whom there is no manifestation made of the Father and the Holy Spirit, and only could be of the Son in the flesh; which latter manifestation is not as the former, being only for a little while, not for ever, for judgment, not for joy, for punishment, not for reward. And We will come unto him: They come to us, in that we go to Them; They come by succouring, we go by obeying; They come by enlightening, we go by contemplating; They come by filling, we go by holding: so Their manifestation to us is not external, but inward; Their abode in us not transitory, but eternal. It follows, And will make Our abode with him.

(Tract. lxxvi. 4) But while the Father and the Son make Their abode with the loving soul, is the Holy Spirit excluded? What meaneth that which is said of the Holy Spirit above: He dwelleth with you, and shall be in you, but that the Spirit makes His abode with us? Unless indeed a man be so absurd as to think that when the Father and the Son come, the Holy Spirit departs, as if to give place to His superiors. Yet even this carnal thought is met by Scripture, in that it says, Abide with you for ever. (v.16) He will therefore be in the same abode with Them for ever. As He did not come without Them, so neither They without Him. As a consequence of the Trinity, acts are sometimes attributed to single persons in it: but the substance of the same Trinity demands, that in such acts the presence of the other Persons also be implied.

(Tract. lxxvi. 5) And perhaps there is a distinction at bottom, since He speaks of His sayings, when they are His own, in the plural number; as when He says, He that loveth Me not, keepeth not My sayings: when they are not His own, but the Father's, in the singular, i. e. as the Word, which is Himself. For He is not His own Word, but the Father's, as He is not His own image, but the Father's, or His own Son, but the Father's.

(Tract. lxxvii. 1) The abode He promised them hereafter is altogether a different one from this present abode He now speaks of. The one is spiritual and inward, the other outward, and perceptible to the bodily sight and hearing.

(Tract. lxxvii. 2) So then the Son speaks, the Holy Spirit teaches: when the Son speaks we take in the words, when the Holy Spirit teaches, we understand those words. The whole Trinity indeed both speaks and teaches, but unless each person worked separately as well, the whole would be too much for human infirmity to take in.

(Tract. xxvii. 2) Suggest, i. e. bring to your remembrance. Every wholesome hint to remember that we receive is of the grace of the Spirit.

(Tract. lxxvii. 2) He left no peace in this world; in which we conquer the enemy, and have love one to another: He will give us peace in the world to come, when we shall reign without an enemy, and where we shall be able to avoid disagreement. This peace is Himself, both when we believe that He is, and when we shall see Him as He is. But why does He say, Peace I leave with you, without the My, whereas He puts in My in, My peace I give unto you? Are we to understand My in the former; or is it not rather left out with a meaning? His peace is such peace as He has Himself; the peace which He left us in this world is rather our peace than His. He has nothing to fight against in Himself, because He has no sin: but ours is a peace in which we still say, Forgive us our debts. (Matt. 6:12) And in like manner we have peace between ourselves, because we mutually trust one another, that we mutually love one another. But neither is that a perfect peace; for we do not see into each other's minds. I could not deny however that these words of our Lord's may be understood as a simple repetition. He adds, Not as the world giveth, give I unto you: i. e. not as those men, who love the world, give. They give themselves peace, i. e. free, uninterrupted enjoyment of the world. And even when they allow the righteous peace, so far as not to persecute them, yet there cannot be true peace, where there is no true agreement, no union of heart.

(de Verb. Dom. serm. ix) But there is a peace which is serenity of thought, tranquillity of mind, simplicity of heart, the bond of love, the fellowship of charity. None will be able to come to the inheritance of the Lord who do not observe this testament of peace; none be friends with Christ, who are at enmity with the Christians.

Judas the holy, not the impure, the follower, not the persecutor of our Lord, asks why Jesus will make himself known to his own but not to the world.… Jesus answers that is because the one loves him and the other does not.… The saints are distinguished from the world by that love that moves those who are of one mind to dwell together in a house. In this house Father and Son make their home and impart that very love to those whom they shall also honor at last with this promised self-manifestation that the disciple asked his master about.

God is not too grand to come, he is not too fussy or shy, he is not too proud—on the contrary he is pleased to come if you do not displease him. Listen to the promise he makes. Listen to him indeed promising with pleasure, not threatening in displeasure, “We shall come to him,” he says, “I and the Father.” To the one he had earlier called his friend, the one who obeys his precepts, the keeper of his commandment, the lover of God, the lover of his neighbor, he says, “We shall come to him and make our abode with him.”

[AD 444] Cyril of Alexandria on John 14:22
It is out of love that the disciple proceeds to make this inquiry, but he clearly does not quite understand our Saviour's language. For our Lord Jesus Christ promised to His Saints a kind of special knowledge and not like that vouchsafed to others. For the characters of Divine |327 mysteries are more defined and shine out far more clearly among the men of God: while those who have not yet attained to such purity of heart as to be able definitely to choose the knowledge of those things which pass understanding by the gift of the Spirit, display their knowledge in bare logical processes, and it is limited to their chance acquaintance with the doctrine that Christ is God and truly the Son of the living God. Although then there lies this vast difference between them, widely dissevering the knowledge of the vulgar from that which is seen in the Saints, the disciple, making no distinction, proceeds to inquire why He does not promise to reveal Himself to all in the world, but only to the Saints. And by the exclamation, How comes it to pass? he means to hint at some such meaning as this: Is the aim of Thy coming amongst us, Lord, to give to some a complete knowledge of Thyself, which to others is wholly denied? For we heard in the prophets that all flesh shall see the salvation of God, and Thou Thyself didst cry out, saying, Rejoice and be glad, daughter of Sion, for lo! I come and shall dwell in thy midst, saith the Lord, and all nations shall flee to the Lord on that day and shall be His people. And when we had continual converse with Thee, we heard with our own ears Thy voice when Thou didst say unto us, I, if I be lifted up from the earth, will draw all men unto Myself; and Thou saidst also to the Jews themselves, And other sheep I have which are not of this fold; them also I must bring, and they shall become one flock, one shepherd. Now then, when the expectation is raised that Thy grace will be poured upon all men and that all will be gathered in to the knowledge of God, and when Thou Thyself hast made us this clear promise and the voice of the holy prophets bears this testimony----What is come to pass? cries the Apostle. Whither has the purpose of the promise then shifted and diverted? Why dost Thou manifest Thyself not to all that are in the world but only to us? This then and no other I think is the meaning of the disciple's words. It is well to show what it was that in fact led him astray from truly apprehending our Saviour's words.

For when our Lord Jesus Christ used the words, A little while, and, the world beholdeth Me no more; but ye behold Me, it is very clear that by the world He did not at all mean those who are in this life or living upon the earth, for all men are in this world, evil and good alike: but by the world He rather meant those who are persuaded to mind earthly; things, who have yoked their understanding to the vanity of the world. The disciple then, not quite understanding this, thought that He said that of all the rest of mankind who dwell in this earthly sphere He would escape the eye, I mean the inner and secret vision of the soul, and would be wholly unseen, and known by no living man but His disciples only; and this was the cause of the disciple's misapprehension. For if he had understood at first, he would never have proceeded to ask, What is come to pass that Thou wilt manifest Thyself unto us, and not unto the world? For he had this meaning I have spoken of suggested to him through his taking the signification of the word in its common and generally-received sense. For we are accustomed to mean by the world, using it in its well-worn and obvious sense, all the inhabitants of the world, just as when one speaks of the city one means all the dwellers in it. Still the disciple, even when he says these words, deserves our admiration. For see how he longs that the glory of the Saviour should shine forth through all the world like the sun, although if he had only been taking thought for his own personal welfare, he might, as he had the promise of knowledge, have enjoyed blessings peculiar to himself. But it was not enough to gratify his soul that the boon should be granted as it were to him individually, but because he was at once a lover of God and of his fellow men he longs for the glory of the Saviour to have a wider field and that grace should be extended to all his brethren. For what joy can equal the being called to the complete knowledge of God?
[AD 444] Cyril of Alexandria on John 14:22-23
Just as we ourselves cannot bear to live among filth and stench and are eager to rid our houses of such if there should be any, will not the pure and all-holy God even more disdain the polluted soul and abhor a heart sunk in the swamp of sxin? Of this there can be no question.

(Hom. xxx. in Evang.) If thou wouldest prove thy love, show thy works. The love of God is never idle; whenever it is, it doeth great things: if it do not work, it is not.

(Hom. xxx.) Into some hearts He cometh, but not to make His abode with them. For some feel compunction for a season and turn to God, but in time of temptation forget that which gave them compunction, and return to their former sins, just as if they had never lamented them. But whoso loveth God truly, into his heart the Lord both comes, and also makes His abode therein: for the love of the Godhead so penetrates him, that no temptation withdraws him from it. He truly loves, whose mind no evil pleasure overcomes, through his consent thereto.

(Hom. xxx.) In proportion as a man's love rests upon lower things, in that proportion is he removed from heavenly love: He that loveth Me not, keepeth not My sayings. To the love then of our Maker, let the tongue, mind, life bear witness.

(Hom. xxx. in Evang.) Paraclete is Advocate, or Comforter. The Advocate then intercedes with the Father for sinners, when by His inward power He moves the sinner to pray for himself. The Comforter relieves the sorrow of penitents, and cheers them with the hope of pardon.

(Hom. xxx.) Unless the Spirit be present to the mind of the hearer, the word of the teacher is vain. Let none then attribute to the human teacher, the understanding which follows in consequence of his teaching: for unless there be a teacher within, the tongue of the teacher outside will labour in vain. Nay even the Maker Himself does not speak for the instruction of man, unless the Spirit by His unction speaks at the same time.

(Hom. xxx.) But why is it said of the Spirit, He shall suggest2 all things to you: to suggest being the office of an inferior? The word is used here, as it is used sometimes, in the sense of supplying secretly. The invisible Spirit suggests, not because He takes a lower place in teaching, but because. He teaches secretly.

The proof of love is its manifestation in deeds. This is why John says in his letter, “He who says, ‘I love God’ and does not observe his commandments is a liar.” Our love is true if we keep our self-will in check according to his commandments. One who is still wandering here and there through his unlawful desires does not really love God, because he is opposing him in his self-will.

Consider, dearly beloved, how great this solemnity is that commemorates the coming of God as a guest in our hearts. If some rich and powerful friend were to enter your home, you would quickly clean the entire house for fear something there might offend your friend’s eyes when he entered. Let anyone then who is preparing his inner house for God cleanse away the dirt of his evil deeds.… He does indeed enter the hearts of some but does not make his home there because through repentance they acquire respect for God, but during a time of temptation they forget that they have repented and so return to committing sins as if they had never wept over them at all. The Lord comes into the heart and makes his home in one who truly loves God and observes his commandments, since the love of his divine nature so penetrates him that he does not turn away from it during times of temptation. That person loves truly whose heart does not consent to be overcome by wicked pleasures.

Or, as after the resurrection He was to appear to them in a body more assimilated to His divinity, that they might not take Him then for a spirit, or a phantom, He tells them now beforehand not to have misgivings upon seeing Him, but to remember that He shows Himself to them as a reward for their keeping His commandments; and that therefore they are bound ever to keep them, that they may ever enjoy the sight of Him.

The Holy Spirit then was both to teach and to bring to remembrance: to teach what Christ had forborne to tell His disciples, because they were not able to bear it; to bring to remembrance what Christ had told them, but which on account of its difficulty, or their slowness of understanding, they were unable to remember.

Christ is the true Son, and so when we receive the Spirit, we are made sons. For it says; ‘you did not receive the spirit of slavery leading you back into fear, but you have received the Spirit of adopted sonship’ [Romans 8:15]. But when we are made sons in the Spirit, it is clear that we are called children of God in Christ... And when the Spirit is given to us-the Saviour said: ‘Receive the Holy Spirit’ [John 20:22]- God [The Father] is in us... But when God is in us, the Son is also in us. For the Lord Himself said: ‘I and the Father will come and make our home with him’ (John 14:23). Next, the Son is life-for He said: ‘I am the life’ [John 14:6]- and so we are said to be given life in the Spirit... But when we are given life in the Spirit, Christ Himself is said to live in us. For it says: ‘I am crucified with Christ. It is no longer I who live, but Christ who lives in me.’ [Galatians 2:19-20]. - "Letters to Separion On the Spirit, Letter 1, Chapter 19"
[AD 407] John Chrysostom on John 14:23
All but saying, As the Father reveals Himself, so also do I. And not in this way only He removed the suspicion, but also by saying, We will make Our abode with him, a thing which does not belong to dreams. But observe, I pray you, the disciple confounded, and not daring to say plainly what he desired to say. For he said not, Woe to us, that Thou diest, and will come to us as the dead come; he spoke not thus; but, How is it that You will show Yourself to us, and not unto the world? Jesus then says, that I accept you, because ye keep My commandments. In order that they might not, when they should see Him afterwards, deem Him to be an apparition, therefore He says these things beforehand. And that they might not deem that He would appear to them so as I have said, He tells them also the reason, Because ye keep My commandments; He says that the Spirit also will appear in like manner. Now if after having companied with Him so long time, they cannot yet endure that Essence, or rather cannot even imagine It, what would have been their case had He appeared thus to them at the first? On this account also He ate with them, that the action might not seem to be an illusion. For if they thought this when they saw Him walking on the waters, although His wonted form was seen by them, and He was not far distant, what would they have imagined had they suddenly seen Him arisen whom they had seen taken and swathed? Wherefore He continually tells them that He will appear, and why He will appear, and how, that they may not suppose Him to be an apparition.
[AD 444] Cyril of Alexandria on John 14:23
When He saw that the disciple did not quite understand, He goes back again to what He said at first, and teaches clearly that He will not manifest Himself to His own, according to the conception he had formed in his mind, but that the manner of His manifestation will be special to His disciples, and not that common to the rest of mankind. For the vulgar, and those, for instance, who have just escaped from the deceitfulness of idols and have been called to the knowledge of the Living God, rest their faith on bare and unquestioned axioms, merely having learnt to know that there is no idol in the world, and that the Living God is One only; while they who have their minds illumined by every virtue and are already in a state to fitly apprehend Divine and hidden mysteries, will receive the torch of the Spirit, and will behold with the eyes of the soul the Lord Himself, Who has taken up His abode in them. The knowledge therefore that the Saints possess is not common to the rest, but is in a manner special and distinct and widely diverse. Christ then benefits us by every kind of word and way. For, first of all, anyone that loves Him is very broadly distinguished from the rest, showing as it seems to me, and as I justly apprehend, that it has not been given to all men to receive the power of His grace, but only to those in whom the glory of intimate connection with Him may be seen indwelling through their keeping His commandments.

Then in what way He will declare Himself and how He will take up His abode in them He goes on to declare. For My Father will love him, He says. For any man who has honoured by his obedience to the Son the Father from Whom He springs, will reap His love as the fruit of his conduct. Then He clearly shows what will be the issue thereof and what profit such a man will gain when He says, I and the Father will come unto him and make Our abode with him. For when our Saviour Christ dwells in us by the Holy Spirit, surely there too will be also His Father; for the Spirit of Christ is the Spirit of the Father Himself also, and the inspired Paul at one time speaks of the Spirit as belonging to the Father, and at another as belonging to the Son: not by way of logical contradiction, but rather saying what is true of either, for it is so in fact. He says then to some: He that raised up Christ Jesus from the dead shall quicken also your mortal bodies through His Spirit that dwelleth in you. Then again, And because ye are sons, God sent forth the Spirit of His Son into your hearts, crying, Abba, Father. Do you see that the same Spirit is of the Father and the Son? When then the Only-begotten dwells in your hearts, the Father is not far from you: for the Son hath in Himself the Father, being of one substance with Him, and is Himself by nature in the Father.

This then we may give as the definition and incontrovertible doctrine of the faith; and I should be glad to question thereupon those who have chosen heretical opinions from excess of ignorance and who arm their tongues with conceits about the Spirit. For what have they to answer when we say to them, "If the Spirit is created and alien to the substance of God, as you say, how can God abide in us through Him? And how can he that receiveth the Spirit partake of God?" For if it is within the bounds of possibility by the agency of any created being whatever for us to partake of the ineffable Divine Nature, what can be found to hinder God the Father thrusting aside the Spirit and by means of any other created being that He chooses to select dwelling in us and sanctifying us? But this is impossible: for no one can partake of the living God by any other means than by the Spirit. The Spirit therefore is God and of God, and is not numbered among creatures, as some think.

This consideration also must be taken into account. That which partakes of anything as being superior in nature and distinct from what it is itself must of necessity be different in nature from that which is partaken of. If then the Spirit is created or made, what remains for the sum of creation to partake of? Surely not itself! For in that case both that which partakes and that which is partaken of would alike owe their origin to a creator. But as it is, we being by nature both created and begotten partake of the Spirit as being different in nature from ourselves. The Spirit therefore is not created. And if this is true, and it is true, the Spirit is God and of God, as we have said. For nothing that exists can escape being included in the category of created things except the living God alone, from Whom the Holy Spirit, ineffably proceeding, dwelleth in us as He from Whom He springs. For He is an attribute of His Substance, and as it were a quality of His holiness.

So much for my controversy with these heretics. But as against the Anomoeans and those who have resolved on war with the Son, who are diseased with a like and kindred madness to these which we have just spoken of, I will refute them as briefly as possible. If a man love Me, he will keep My word; and My Father will love Him, and We will come unto him, and make Our abode with him. What, then, my good Sirs, have you to say if any one chooses to inquire and desires to know of you whether we shall have two Gods indwelling in us, the Father and the Son, or whether you conceive of one God as really existing in us. For if the Son is wholly distinct in nature and is conceived of as having a separate nature, how can we avoid believing that there is a duality of Gods in us when we keep His commandment? And if we are temples of one, that is, and not of two Gods, when the Father and the Son take up Their abode in us, how can you prove that the two coalesce unto unity in us, as, according to your crazy notion, identity of nature is out of the question? For either you must say that Christ has told us falsehoods, and that the Father only dwells in us by the Spirit, or He Himself dwells in us and the Father is absent. But this is absurd, and there is one God in us when we receive both. The Only-begotten then will appear to be not different in substance from His Father, but of Him and in Him, as the light includes the effulgence which proceeds from it. Such, and no other, is the true meaning of the mystery. And certainly the inspired Paul did not call us temples of two Gods, but clearly of one and the same. Know ye not, he says, that ye are a temple of God, and that the Spirit of God dwelleth in you? You see that making the Father and Son coalesce in identity of Substance he says that we have been made temples not of Gods but of one God. Why then do you bring your rash arguments into conflict with the power of the truth, and sow the seed of your poisonous impiety in those who are wont heedlessly to handle the holy and inspired writings?
[AD 108] Ignatius of Antioch on John 14:24
But the Holy Spirit does not speak His own things, but those of Christ, and that not from himself, but from the Lord; even as the Lord also announced to us the things that He received from the Father. For, says He, "the word which ye hear is not Mine, but the Father's, who sent Me."

So that he that hears not these sayings not only does not love Me, but neither does he love the Father.

And how is the word 'yours' and 'not yours'? This means, I speak not without the Father, nor say anything of Myself contrary to what seems good to Him.
[AD 410] Gaudentius of Brescia on John 14:24
He made known to them many things concerning the oneness of his own divinity with that of the Father. He made clear that there was no separation between them so that even the words he spoke to them were not his, he declared, but the Father’s. “And the word that you have heard is not mine but the Father’s who sent me.” In this sentence he makes it abundantly clear that all who reject the teaching of his only-begotten Son reject the teaching of the Father also, since the Son says that the words he spoke are not his but the Father’s. And from this it follows that if they are the words of the Father, they are also the words of the Son, for he declares, “All things whatever the Father has are mine.” … And this is clearly because of the oneness of the divine substance that recognizes nothing as part of it that does not belong to the divine nature.

[AD 444] Cyril of Alexandria on John 14:24
He that loveth Me not keepeth not My words.

When He has premised and rightly defined who those that love Him are, and of what blessings they will partake, He at once proceeds to treat of others who have not yet chosen to love Him. "For they will not keep My words," He says; for this is the meaning of the saying, "he will not keep My word," spoken as if of and concerning one man, even though it has a broad and generic signification. And this that He says has a very apt connection with what precedes. For, if the keeping of His commandments or His Word is a clear proof of love towards Him, surely the converse of this will be true. For treating His bidding as of no account and thrusting His commandment aside will be a sign that we refuse to love Him, as these are the acts of men inured to evil-doing. But just as He promised that together with God the Father He would Himself abide with those who keep His laws, for the same reason, I think, He will pass away from and wholly abandon those who do the reverse. For thus the truth of Solomon's saying will be seen: Into the soul of him that maketh iniquity wisdom will not enter, nor dwell in the body given over to sin. For in common life you can observe that a similar result follows: for does not a man gain repute by conversing with those who are likeminded and who choose the same path of life, rather than with others? And Every creature loves his like, according to the saying, and Man will seek union with his like. And if it seems most desirable even among ourselves to live with those of similar habits to ourselves, how can we escape the reflection that this is still more the case with God? For as He is good by nature and the beginning and source of all virtue, He takes up His abode not in the lovers of wickedness but in the workers of virtue, and disdains the impure, and with good reason. As then we ourselves are naturally eager to rid our houses of filth and stench if any such there be, disdaining to live in them, will not the pure and all-holy God still more disdain the polluted soul, and abominate a heart sunk in the slough of sin? Of this there can be no question. For that he that doth not keep His commandment will be found among these and not elsewhere, being as he is impure and of filthy lusts, our speculation will perforce teach you. For in not keeping the Divine commands the origin of sin is found.

For just as the deprivation of light introduces its opposite, I mean darkness, just so refusing to do virtuous acts causes wickedness to spring up. For inasmuch as the subject-matter that underlies them is one and the same, things diverse from each other in quality may admit of comparison (I am far from saying they are identical) according to the law of contraries.

And so vice and virtue are separate and widely opposed to each other in quality, or how could one speak without falling into error? But both characters cannot belong to any one among us in the same relation and be fulfilled in action. For either a man is good or bad, though he may not have reached the height of iniquity or virtue. Then when the one principle is powerful within us, the other, that is the opposite, will be weak. And so if the formal principle of virtue consist in keeping His commandments, is it not most plain that in not keeping them wickedness originates? Just as to have in himself the Father and the Son, which is the origin and basis of all satisfaction of soul and glory, is in store for him that keeps His commandments, so he that keepeth them not is wholly cut off from participation in the ineffable Divine nature; which is, in effect, incapacity to enjoy any blessing. If any man then think it a good and desirable thing to partake of the Divine nature and to have God Who is the Father of the universe indwelling and abiding in the shrine of the heart by His Son, in the Spirit, let him thoroughly purge his soul, and wash away the stain of wickedness, by whatever means he can; and most of all, by all kinds of well-doing. For then will he become truly the temple of God; and He will rest and abide in him, according to the Scripture. For then it will not be with him as it was with the lawyer mentioned in the Gospels, who did not wait for grace from the Saviour, but said that he went self-called to follow Him; and, eager to seize so desirable a blessing, exclaimed, Master, I will follow Thee whithersoever Thou goest: but what said Christ to him as in a parable and in riddles, The foxes have holes and the birds of the heaven have nests, but the Son of Man hath not where to lay His Head. By foxes and birds of the heaven He meant wicked and unclean devils, and the spirits of the world and of the air, which love to dwell and take up their abode in the hearts of pleasure-seekers, fulfilling their own lusts, and so cramping the miserable souls of those who receive them that God can find no place at all for rest in them. This is what He means by laying His Head.

Let us then cleanse our hearts from every defilement, for so will God dwell in us and will render us proof against all the malice of the devil, and will make us happy and blessed, and will render us partakers of His ineffable Divine nature.
[AD 444] Cyril of Alexandria on John 14:24
And the word which ye hear is not Mine but the Father's Who sent Me.

He once more deals with a difficult subject which required of Him accurate explanation, and again brings forward illustrations by which they might have their understanding better fitted to fully comprehend the depth of the mystery. And He confirms the minds of His hearers in order that they might not be allured by the ignorant prejudices of the Jews, and in their desire to bring their own ideas into conformity with the Jewish do despite unto the holy teaching of the Gospel. What I wish to say is this in plain words: For the law having a shadow and an impressed type until a time of reformation, according to the saying of Paul, hath been our tutor to bring us unto Christ, and provided, as it were, a preliminary training for virtue according to godliness. If any one then were to call the Mosaic dispensation preparatory to true worship in Spirit, he would not miss the mark. For, for this reason, the Law brought nothing to perfection; but our Lord Jesus Christ showed us no longer the shadows of things, but the reality itself openly, no longer sketching the outline of virtue in types and figures, as Moses did, but setting it up naked in the public sight, accomplishing the perfect man in righteousness. The instruction of the words of Christ was then a shifting and moulding of the types into truth. And since, as the truth was already shining forth, it was superfluous for the shadow any longer to prevail, Christ ordained that those who came to Him by faith should no longer frame their conduct by the types of the Law. This was very grievous to the Jews, for they thought that Christ came to destroy the old Law, although they heard Him saying openly, I come not to destroy the Law, but to fulfil. For I say unto you, one jot or one tittle shall in no wise pass away from the Law till all things be accomplished. The realisation of excellence which was introduced by the laws of Christ brings with it the fulfilment of the shadow of the Law, as we have just said. For inasmuch as in their headstrong passion they became backsliders into disobedience, and assuming a zeal for the Law not according to knowledge, they thought themselves to be advocating the Law by rejecting the commandments of Christ, it was for this very reason in order that He might not seem to any to be laying down some new and peculiar laws adverse to the will of God the Father He conveyed this useful and necessary rebuke----The word which ye hear is not Mine, but the Father s Who sent Me. Let not any one of those who come to Me by faith, He says, think that I have made any discourse not in accord with the will of God the Father. The tidings of the Gospel are His and not another's, but He gave them not as ashamed of the older enactments, nor again as though the better commandment had been unveiled at the moment; but rather because the type had been moulded into reality at the fitting time. For He That said those things by Me to the men of old time says this also now to you: for I am the living Word That interprets the ineffable Will of God the Father, wherefore am I called the Angel of great counsel.

For either after this manner we shall receive the saying, I mean the following ---- The word which ye hear is not Mine, but the Father s Who sent Me, or we shall understand it in another way. For He says that His own word is the word of God the Father, that they who keep it may know that they honour God when they are persuaded by the words which come from Him: while others, falling into the contrary extreme and not disdaining by disobedience to insult the commandment given to them, sin against the nature of the Most Highest. Now it was possible in two ways to confirm the minds of His hearers: for either the wish to honour God would incline them at all events to obedience, or the fear of coming into conflict with Him would also have this effect. For the calculation of what is useful and expedient runs through both methods. And when He says, "It is not My word," He does not at all put out of our sight the peculiar character which He bears as the Word and God. And, while He still wears His homely shape, and appears and truly is in the guise of manhood, and is really like as we are when He is saying this, He is not willing that His word should be thought merely human, but really Divine and regal; of necessity merging His character in that of the Father, in order that He might not by sundering Himself admit the conception of two Sons, as the Son is one and the same both before and after His Incarnation. For Christ is one, and not two, as some say: for the Word proceeding from the Father, being God, became flesh according to the saying of John not by conversion into flesh, but by enshrining His divinity in flesh from the womb of the holy virgin. In order then that we may not think His word is merely human, or divest the Gospel teaching of its Divine character, but may be convinced that it comes from the God Who is over all, appropriately and with great reason, inasmuch as He was then appearing to them in the form of man, He attributes His words to His Divine Nature, as in the character of God the Father, from Whom and in Whom He is by nature as His effulgence and His word and the Express Image of His Person.
[AD 604] Gregory the Dialogist on John 14:24
You know, dearly beloved, that the one speaking, the only-begotten Son, is the Father’s Word. Therefore the word that the Son speaks is not his but the Father’s, because the Son himself is the Father’s Word.

[AD 430] Augustine of Hippo on John 14:25
1. In the preceding lesson of the holy Gospel, which is followed by the one that has just been read, the Lord Jesus had said that He and the Father would come to those who loved Them, and make Their abode with them. But He had also already said above of the Holy Spirit, But you shall know Him; for He shall dwell with you, and shall be in you John 14:17: by which we understood that the divine Trinity dwells together in the saints as in His own temple. But now He says, These things have I spoken unto you while [still] dwelling with you. That dwelling, therefore, which He promised in the future, is of one kind; and this, which He declares to be present, is of another. The one is spiritual, and is realized inwardly by the mind; the other is corporal, and is exhibited outwardly to the eye and the ear. The one brings eternal blessedness to those who have been delivered, the other pays its visits in time to those who await deliverance. As regards the one, the Lord never withdraws from those who love Him; as regards the other, He comes and goes. These things, He says, have I spoken unto you, while [still] dwelling with you; that is, in His bodily presence, wherein He was visibly conversing with them.

2. But the Comfort, He adds, [which is] the Holy Ghost, whom the Father will send in my name, He shall teach you all things, and bring all things to your remembrance, whatsoever I have said unto you. Is it, then, that the Son speaks, and the Holy Spirit teaches, so that we merely get hold of the words that are uttered by the Son, and then understand them by the teaching of the Spirit as if the Son could speak without the Holy Spirit, or the Holy Spirit teach without the Son: or is it not rather that the Son also teaches and the Spirit speaks, and, when it is God that speaks and teaches anything, that the Trinity itself is speaking and teaching? And just because it is a Trinity, its persons required to be introduced individually, so that we might hear it in its distinct personality, and understand its inseparable nature. Listen to the Father speaking in the passage where you read, The Lord said unto me, You are my Son: listen to Him also teaching, in that where you read, Every man that has heard, and has learned of the Father, comes unto me. The Son, on the other hand, you have just heard speaking; for He says of Himself, Whatsoever I have said unto you: and if you would also know Him as a Teacher, bethink yourself of the Master, when He says, One is your Master, even Christ. Matthew 23:10 Furthermore, of the Holy Spirit, whom you have just been told of as a Teacher in the words, He shall teach you all things, listen to Him also speaking, where you read in the Acts of the Apostles, that the Holy Spirit said to the blessed Peter, Go with them, for I have sent them. The whole Trinity, therefore, both speaks and teaches: but were it not also brought before us in its individual personality, it would certainly altogether surpass the power of human weakness to comprehend it. For as it is altogether inseparable in itself, it could never be known as the Trinity, were it always spoken of inseparably; for when we speak of the Father, and the Son, and the Holy Spirit, we certainly do not pronounce them simultaneously, and yet in themselves they cannot be else than simultaneous. But when He added, He will bring to your remembrance, we ought also to understand that we are commanded not to forget that these pre-eminently salutary admonitions are part of that grace which the Holy Spirit brings to our remembrance.

3. Peace, He said, I leave with you, my peace I give unto you. It is here we read in the prophet, Peace upon peace: peace He leaves with us when going away, His own peace He will give us when He comes in the end. Peace He leaves with us in this world, His own peace He will give us in the world to come. His own peace He leaves with us, and abiding therein we conquer the enemy. His own peace He will give us when, with no more enemies to fight, we shall reign as kings. Peace He leaves with us, that here also we may love one another: His own peace will He give us, where we shall be beyond the possibility of dissension. Peace He leaves with us, that we may not judge one another of what is secret to each, while here on earth: His own peace will He give us, when He will make manifest the counsels of the heart; and then shall every man have praise of God. 1 Corinthians 4:5 And yet in Him and from Him it is that we have peace, whether that which He leaves with us when going to the Father, or that which He will give us when we ourselves are brought by Him to the Father. And what is it He leaves with us, when ascending from us, save His own presence, which He never withdraws? For He Himself is our peace who has made both one. Ephesians 2:14 It is He, therefore, that becomes our peace, both when we believe that He is, and when we see Him as He is. 1 John 3:2 For if, so long as we are in this corruptible body that burdens the soul, and are walking by faith, not by sight, He forsakes not those who are sojourning at a distance from Himself; 2 Corinthians 5:6-7 how much more, when we have attained to that sight, shall He fill us with Himself?

4. But why is it that, when He said, Peace I leave with you, He did not add, my; but when He said, I give unto you, He there made use of it? Is my to be understood even where it is not expressed, on the ground that what is expressed once may have a reference to both? Or may it not be that here also we have some underlying truth that has to be asked and sought for, and opened up to those who knock thereat? For what, if by His own peace He meant such to be understood as that which He possesses Himself? Whereas the peace, which He leaves us in this world, may more properly be termed our peace than His. For He, who is altogether without sin, has no elements of discord in Himself; while the peace we possess, meanwhile, is such that in the midst of it we have still to be saying, Forgive us our debts. Matthew 6:12 A certain kind of peace, accordingly, we do possess, inasmuch as we delight in the law of God after the inward man: but it is not a full peace, for we see another law in our members warring against the law of our mind. Romans 7:22-23 In the same way we have peace in our relations with one another, just because, in mutually loving, we have a mutual confidence in one another: but no more is such a peace as that complete, for we see not the thoughts of one another's hearts; and we have severally better or worse opinions in certain respects of one another than is warranted by the reality. And so that peace, although left us by Him, is our peace: for were it not from Him, we should not be possessing it, such as it is; but such is not the peace He has Himself. And if we keep what we received to the end, then such as He has shall we have, when we shall have no elements of discord of our own, and we shall have no secrets hid from one another in our hearts. But I am not ignorant that these words of the Lord may be taken so as to seem only a repetition of the same idea, Peace I leave with you, my peace I give unto you: so that after saying peace, He only repeated it in saying my peace; and what He had meant in saying I leave with you, He simply repeated in saying I give unto you. Let each one understand it as he pleases; but it is my delight, as I believe it is yours also, my beloved brethren, to keep such hold of that peace here, where our hearts are making common cause against the adversary, that we may be ever longing for the peace which there will be no adversary to disturb.
5. But when the Lord proceeded to say, Not as the world gives, give I unto you, what else does He mean but, Not as those give who love the world, give I unto you? For their aim in giving themselves peace is that, exempt from the annoyance of lawsuits and wars, they may find enjoyment, not in God, but in the friendship of the world; and although they give the righteous peace, in ceasing to persecute them, there can be no true peace where there is no real harmony, because their hearts are at variance. For as one is called a consort who unites his lot (sortem) with another, so may he be termed concordant whose heart has entered into a similar union. Let us, therefore, beloved, with whom Christ leaves peace, and to whom He gives His own peace, not after the world's way, but in a way worthy of Him by whom the world was made, that we should be of one heart with Himself, having our hearts run into one, that this one heart, set on that which is above, may escape the corruption of the earth.
[AD 444] Cyril of Alexandria on John 14:25
Contrariwise, His speech has in it the human element, and is not quite foreign to the standards we apply to ourselves, to the extent that the mind into which it entered was fitted to receive the words before us. Perhaps some one will plausibly say that Christ is not amongst us according to the power of His Godhead, although He fills the Universe and is not wholly separated from anything, but rather encompasses with unspeakable might earth and heaven, and does not leave the depths of the abyss: for where is not God"? When, then, He says, These things have I spoken unto you, while yet abiding with you, we must think that He there speaks as a man; and since He was about to vanish from our sight, I mean according to the flesh, He says this when the preparation for His departure into heaven was complete; and He says that the most perfect and complete revelation to us of the mystery is through the Comforter, that is the Holy Ghost, sent from the Father in His Name, I mean that of the Son. For as His Spirit is Christ in us, therefore He says, He shall teach you all things that I said. For since He is the Spirit of Christ, and His mind, as it is written, which is nought else but what He is, in regard to identity of nature, even though He be both conceived of and is existent, He knows all that is in Him. And Paul will be our witness, saying, For who knoweth the things of a man, save the spirit of the man which is in him? even so the things of God none knoweth save the Spirit of God. Wherefore as knowing what is in the counsel of the Only-begotten, He reporteth all things to us, not having the knowledge thereof from learning, that is; that He may not seem to fill the rank of a minister and to transmit the words of another but as His Spirit, as we said just now, and knowing untaught all that belongeth to Him of Whom and in Whom He is, He revealeth to the Saints the Divine mysteries; just as man's mind too, knowing all things that are therein, ministereth externally by uttered word the desires of the soul whose mind it is, being mentally discerned in the thoughts, and named as something else than itself, not other by nature, but as a part complemental of the whole, existing in it and believed to go forth from it. Such a relation as this is inapplicable to the ineffable Divine Nature. For small is all the power of illustrations, even if it go on to subtleties. The perfect knowledge then is begotten in the Saints by the Spirit. And indeed the inspired Paul exhorts some: I also, having heard of the faith in the Lord Jesus which is among you, and the love which ye show toward all the Saints, cease not to give thanks for you, making mention of you in my prayers; that the God of our Lord Jesus Christ, the Father of glory, may give unto you a spirit of wisdom and revelation in the knowledge of Him; having the eyes of your heart enlightened, that ye may know what is the hope of His calling, what the riches of the glory of His inheritance in the Saints, and what the exceeding greatness of His power to us-ward who believe, according to the working which He hath wrought in Christ, when He raised Him from the dead, and made Him to sit at His right hand in the heavenly places, far above all rule, and authority, and power, and dominion, and every name that is named, not only in this world, but also in that which is to come. For in the revelation of these things by the Spirit working in us in an unspeakable way, we see the deep meaning of the Incarnation and the power of the hidden mystery. And that His Spirit, indwelling in the Saints, accomplishes the presence and the power of Christ Himself and teaches all things that He has spoken unto us, Paul will once more make none the less clear to us by the words: For this cause I bow my knees unto the Father, from Whom every family both in heaven and on earth is named, that He would grant you, according to the riches of His glory, that ye may be strengthened with power through His Spirit in the inward man; that Christ may dwell in your hearts through faith to the end; that ye, being rooted and grounded in love, may be strong to apprehend with all the Saints what is the breadth, and length, and depth, and height, and to know the love of Christ, which passeth knowledge, that ye may be filled unto all the fulness of God.

Furthermore, we must show that when He said that all would be revealed by the Spirit to the Saints, He does not give them over to another master----do not think that: but He keeps them by His side, through the Spirit, no longer seen by the eye of the flesh, but rather gazed upon as became a God by the intellectual vision of the heart.
[AD 461] Leo the Great on John 14:25
He withdrew his bodily presence for a time, for he is to abide at the right hand of the Father until the times that have been divinely decreed for the multiplication of the children of the church are accomplished. And then in the same body in which he ascended he will come again to judge the living and the dead. And so what was visible in Christ is now veiled in mystery. And, so that faith might be more perfect and more steadfast, vision was succeeded by revealed truth whose authority the hearts of the faithful, illumined by light from above, would now begin to follow.

[AD 379] Basil of Caesarea on John 14:26
The Spirit is simple in being. His powers are many. They are entirely present everywhere and in everything. He is distributed but does not change. He is shared yet remains whole. Consider the analogy of the sunbeam: each person on whom its kindly light falls rejoices as if the sun existed for him alone, yet it illumines land and sea and is master of the atmosphere. In the same way, the Spirit is given to each one who receives him as if he were the possession of that person alone, yet he sends forth sufficient grace to fill the entire universe. Everything that partakes of his grace is filled with joy according to its capacity—the capacity of its nature, not of his power.The Spirit does not take up his abode in someone’s life through a physical approach. How could a corporeal being approach the bodiless One? Instead, the Spirit comes to us when we withdraw ourselves from evil passions that have crept into the soul through its friendship with the flesh, alienating us from a close relationship with God. Only when a person has been cleansed from the shame of his evil and has returned to his natural beauty, and [only when] the original form of the royal image has been restored in him, is it possible for him to approach the Paraclete. Then, like the sun, he will show you in himself the image of the invisible, and with purified eyes you will see in this blessed image the unspeakable beauty of its prototype. Through him hearts are lifted up, the infirm are held by the hand, and those who progress are brought to perfection. He shines on those who are cleansed from every spot and makes them spiritual people through fellowship with himself. When a sunbeam falls on a transparent substance, the substance itself becomes brilliant and radiates light from itself. So too Spirit-bearing souls, illumined by him, finally become spiritual themselves, and their grace is sent forth to others. From this comes knowledge of the future, understanding of mysteries, apprehension of hidden things, distribution of wonderful gifts, heavenly citizenship, a place in the choir of angels, endless joy in the presence of God, becoming like God, and the highest of all desires, becoming God.

The Son can come in the Father’s name only, consistent with the proper relationship of the Son to the Father and the Father to the Son. No one else comes in the name of the Father, but in the name of God, of the Lord, of the Almighty, and the like.… As servants who come in the name of their Lord do so as being the servants of that Lord, so the Son who comes in the name of the Father bears that name as being the acknowledged only-begotten Son of the Father. That the Holy Spirit then is sent in the Son’s name, by the Father, shows that he is in unity with the Son: from this he is said also to be the Spirit of the Son and to make those sons [children] by adoption who are willing to receive him. The Holy Spirit who then comes in the name of the Son from the Father shall teach those who are established in the faith of Christ all things—all things that are spiritual, that is, both the understanding of truth and the sacrament of wisdom. But he will teach, not like those who have acquired an art or knowledge by study and industry but as being the very art, doctrine, knowledge itself. As being this himself, the Spirit of truth will impart the knowledge of divine things to the mind.

He wanted them, in other words, to see his departure as a blessing. Notice how he often calls [the Spirit] Comforter, because of the troubles they had to deal with. And since they were still troubled, even after hearing all this, because of their sadness, the struggles and his departure, he calms them again by saying, “Peace I leave you.” … And because he brings up the subject of leaving again, which is enough in itself to trouble them, he again says, “Do not let your heart be troubled, neither let it be afraid.”

But the Holy Spirit was not only in heaven, nor was he only on the earth.

But so that a clear faith and separate belief in the Father, Son and Holy Spirit might be given to those who believe, it is accordingly written that the Father sends both the Son and the Holy Spirit, since neither he who sends nor he who is sent can be believed to be God if there is a place where he is and a place where he is not. Let us believe in the Son speaking to us, since he is the Truth: “I am not alone,” he says, “because the Father is with me.” And again, speaking of the Holy Spirit, he says, “But if I by the Spirit of God cast out devils.” … Accordingly, since nowhere is the divinity of the Trinity not present, it is part of the divine plan for the redemption of humankind that it is spoken of as both sending and being sent. For otherwise the human mind could not grasp that the Father is the Father, and the Son is the Son and the Holy Spirit is the Holy Spirit, unless it should learn their separateness by the naming of one as sent and one as sending.

Many of you, dearly beloved, know that the Greek word Paraclete means in Latin “advocate” or “consoler.” He is called an advocate because he intervenes before the Father’s justice on behalf of the wrongdoings of sinners. He who is of one substance with the Father, and the Son is said to plead earnestly on behalf of sinners because he causes those whom he fills to do so. This is why Paul says, “For the Spirit himself pleads for us with unutterable groanings.” But one who pleads is of less importance than the one receiving the plea. How is the Spirit, then, who is not less important, said to plead? The Spirit pleads, rousing those he fills to plead. The same Spirit is called a consoler because when he prepares a hope of pardon for those grieving over their sins he is lifting up their hearts from sorrow and affliction.

[AD 604] Gregory the Dialogist on John 14:26
It is only right that Jesus promised, “He will teach you all things,” because unless the Spirit is present in the heart of a listener, the teacher’s utterance is useless. No one should attribute to his teacher what he understands from him, because unless there is an inner teacher, the one outside is exerting himself in vain. You all hear equally the single voice of the person speaking, and yet you each have a different perception of the meaning. The voice is not different—why do your hearts understand it differently? Is it not that through what the speaker’s voice counsels generally there is an inner master who teaches each one individually about its meaning? John says this about the anointing of the Spirit: “His anointing teaches you about everything.” No one is instructed by a voice when his heart is not anointed by the Spirit. But why do I speak in this way about human teaching when our Creator himself does not speak for the instruction of any person unless he speaks to that person by the anointing of the Spirit?

The Holy Spirit warns us, and says, "What man is he that desireth to live, and would fain see good days? Refrain thy tongue from evil, and thy lips that they speak no guile. Eschew evil, and do good; seek peace, and ensue it." The son of peace ought to seek peace and ensue it. He who knows and loves the bond of charity, ought to refrain his tongue from the evil of dissension. Among His divine commands and salutary teachings, the Lord, when He was now very near to His passion, added this one, saying, "Peace I leave with you, my peace I give unto you." He gave this to us as an heritage; He promised all the gifts and rewards of which He spoke through the preservation of peace. If we are fellow-heirs with Christ, let us abide in the peace of Christ; if we are sons of God, we ought to be peacemakers. "Blessed," says He, "are the peacemakers; for they shall be called the sons of God." It behoves the sons of God to be peacemakers, gentle in heart, simple in speech, agreeing in affection, faithfully linked to one another in the bonds of unanimity.

That charity and brotherly affection are to be religiously and stedfastly practised. In Malachi: "Hath not one God created us? Is there not one Father of us all? Why have ye certainly deserted every one his brother? " Of this same thing according to John: "Peace I leave with you, my peace I give unto you." Also in the same place: "This is my commandment, That ye love one another, even as I have loved you. Greater love than this has no man, than that one should lay down his life for his friends." Also in the same place: "Blessed are the peacemakers, for they shall be called the sons of God." Also in the same place: "Verily I say unto you, That if two of you shall agree on earth concerning everything, whatever you shall ask it shall be given you from my Father which is in heaven. For wherever two or three are gathered together in my name, I am with them." Of this same thing in the first Epistle to the Corinthians: "And I indeed, brethren, could not speak unto you as to spiritual, but as to carnal, as to babes in Christ. I have given you milk for drink, not meat: for while ye were yet little ye were not able to bear it, neither now are ye able. For ye are still carnal: for where there are in you emulation, and strife, and dissensions, are ye not carnal, and walk after man? " Likewise in the same place: "And if I should have all faith, so that I can remove mountains, but have not charity, I am nothing. And if I should distribute all my goods for food, and if I should deliver up my body to be burned, but have not charity, I avail nothing. Charity is great-souled; charity is kind; charity envieth not; charity dealeth not falsely; is not puffed up; is not irritated; thinketh not evil; rejoiceth not in injustice, but rejoiceth in the truth. It loveth all things, believeth all things, hopeth all things, beareth all things. Charity shall never fail." Of this same thing to the Galatians: "Thou shalt love thy neighbour as thyself. But if ye bite and accuse one another, see that ye be not consumed one of another." Of this same thing in the Epistle of John: "In this appear the children of God and the children of the devil. Whosoever is not righteous is not of God, and he who loveth not his brother. For he who hateth his brother is a murderer; and ye know that no murderer hath eternal life abiding in him." Also in the same place: "If any one shall say that he loves God, and hates his brother, he is a liar: for he who loveth not his brother whom he seeth, how can he love God whom he seeth not? " Of this same thing in the Acts of the Apostles: "But the multitude of them that had believed acted with one soul and mind: nor was there among them any distinction, neither did they esteem as their own anything of the possessions that they had; but all things were common to them." Of this same thing in the Gospel according to Matthew: If thou wouldest offer thy gift at the altar, and there rememberest that thy brother hath ought against thee; leave thou thy gift before the altar, and go; first be reconciled to thy brother, and then come and offer thy gift at the altar." Also in the Epistle of John: "God is love l and he that dwelleth in love dwelleth in God, and God in him." Also in the same place: "He who saith he is in the light, and hateth his brother, is a liar, and walketh in darkness even until now."

Christ stopped those who were waging war and established peace by destroying the might of those waging war. Those opposing powers have no power against those of the household of Christ who came out of captivity as soon as they learned to know the Redeemer. Therefore, they have an unshakeable peace because it is a peace of the soul that has been led to freedom and has put off fear and shed all trouble. Since these good things of the soul have been assured and cannot be taken away, the peace of the soul has been made sure.

The God of peace is Christ, who said, “My peace I give you, my peace I leave you.” … But the peace of God is one thing, the peace of the world another, because even malignant and foul people have peace, but [this is] to their damnation. The peace of Christ is free from sins. For it flees faithlessness, spurns trickery and rejects evil deeds. This peace is pleasing and congenial to God, hostile to the devil. A person who has peace will also have love and the God of both to keep him safely guarded forever.

[AD 397] Ambrose of Milan on John 14:27
It is the part of those who have been perfected not to be easily influenced by worldly things or to be troubled with fear or tormented with suspicion or stunned with dread or distressed with pain. Rather, as if on a shore of total safety, they ought to calm their spirit, immovable as it is in the anchorage of faith against the rising waves and tempests of the world. Christ brought this support to the spirits of Christians when he brought an inner peace to the souls of those who had proved themselves, so that our heart should not be troubled or our spirit be distressed.… The fruit of peace is the absence of disturbance in the heart. In short, the life of the righteous person is calm, but the unrighteous person is filled with disquiet and disturbance. Therefore the ungodly person is struck down more by his own suspicions than most people are by the blows of others, and the stripes of the wounds in his soul are greater than those in the bodies of those who are lashed by others.

(Hom. lxxv. 3) After saying, Peace I leave with you, which was like taking farewell, He consoles them: Let not your heart be troubled, neither let it be afraid: the two feelings of love and fear were now the uppermost in them.

(Hom. lxxv. 4) Or thus: The Apostles did not yet know what the resurrection was of which He spoke when He said, I go, and come again to you; or what they ought to think of it. They only knew the great power of the Father. So He tells them: Though ye fear I shall not be able to save Myself, and do not trust to My appearing again after My crucifixion; yet when ye hear that I go to My Father, ye should rejoice, because I go to one greater, one able to dissolve and change all things. All this is said in accommodation to their weakness: as we see from the next words; And now I have told you before it come to pass; that when it does come to pass, ye may believe.

(Hom. lxxvi. 1) Arise, let us go hence, is the beginning of the sentence which follows. The time and the place (they were in the midst of a town, and it was night time) had excited the disciples' fears to such a degree, that they could not attend to any thing that was said, but rolled their eyes about, expecting persons to enter and assault them; especially when they heard our Lord say, Yet a little while I am with you; and, The prince of this world cometh. To quiet their alarm then, He takes them to another place, where they imagine themselves safe, and would be able to attend to the great doctrines which He was going to set before them.

All but saying, What are you harmed by the trouble of the world, provided ye be at peace with Me? For this peace is not of the same kind as that. The one is external, is often mischievous and unprofitable, and is no advantage to those who possess it; but I give you peace of such a kind that you be at peace with one another, which thing renders you stronger. And because He said again, I leave, which was the expression of One departing, and enough to confound them, therefore He again says,

Let not your heart be troubled, neither let it be afraid.

Do you see that they were affected partly by loving affection, partly by fear?

This makes you stronger.”

[AD 430] Augustine of Hippo on John 14:27-31
(Tract. lxxviii. 1) Though He was only going for a time, their hearts would be troubled and afraid for what might happen before He returned; lest in the absence of the Shepherd the wolf might attack the flock: Ye have heard how I said unto you, I go away, and come again to you. In that He was man, He went: in that He was God, He stayed. Why then be troubled and afraid, when He left the eye only, not the heart? To make them understand that it was as man that He said, I go away, and come again to you; He adds, If ye loved Me ye would rejoice, because I said, I go unto My Father; for My Father is greater than I. In that the Son then is unequal with the Father, through that inequality He went to the Father, from Him to come again to judge the quick and dead: in that He is equal to the Father, He never goes from the Father, but is every where altogether with Him in that Godhead, which is not confined to place. Nay, the Son Himself, because that being equal to the Father in the form of God, He emptied Himself, not losing the form of God, but taking that of a servant, is greater even than Himself: the form of God which is not lost, is greater than the form of a servant which was put on. In this form of a servant, the Son of God is inferior not to the Father only, but to the Holy Ghost; in this the Child Christ was inferior even to His parents; to whom we read, He was subject. Let us acknowledge then the twofold substance of Christ, the divine, which is equal to the Father, and the human, which is inferior. But Christ is both together, not two, but one Christ: else the Godhead is a quaternity, not a Trinity. Wherefore He says, If ye loved Me, ye would rejoice, because I said, I go to the Father; for human nature should exult at being thus taken up by the Only Begotten Word, and made immortal in heaven; at earth being raised to heaven, and dust sitting incorruptible at the right hand of the Father. Who, that loves Christ, will not rejoice at this, seeing, as he doth, his own nature immortal in Christ, and hoping that He Himself will be so by Christ.

(Tract. lxxix. 1) But is not the time for belief before a thing takes place? Is it not the praise of faith, that it believes what it does not see? according to what is said below to Thomas: Because thou hast seen, thou hast believed. He saw one thing, believed another: what he saw was man, what he believed was God. And if belief can be talked of with reference to things seen, as when we say that we believe our eyes; yet it is not mature faith, but is merely preparatory to our believing what we do not see. When it has come to pass; then He says, because after His death they would see Him alive again, and ascending to His Father; which sight would convince them that He was the Christ, the Son of God; able as He was to do so great a thing, and to foretell it. Which faith however would not be a new, but only an enlarged faith; or a faith which had failed at His death, and been renewed by His resurrection.

(Tract. lxxix. 2) i. e. the devil; the prince of sinners, not of creatures; as the Apostle saith, Against the rulers of this world. (Eph. 6:12) Or, as He immediately adds by way of explanation, this darkness, meaning, the ungodly. And hath nothing in Me. God had no sin as God, nor had His flesh contracted it by a sinful birth, being born of the Virgin. But how, it might be asked, canst thou die, if thou hast no sin: He answers, But that the world may know that I love the Father, and as the Father gave Me commandment, even so I do. Arise, let us go hence. He had been sitting at table with them all this time. Let us go: i. e. to the place, where He, Who had done nothing to deserve death, was to be delivered to death. But He had a commandment from His Father to die.

(contr. Serm. Arrian. c. xi.) That the Son is obedient to the will and commandment of the Father, no more shows a difference in the two, than it would in a human father and son. But over and above this comes the consideration that Christ is not only God, and as such equal to the Father, but also man, and as such inferior to the Father.

And yet it is in him and from him that we have peace, whether it is the peace he leaves with us when going to the Father or that which he will give us when we ourselves are brought by him to the Father. And what is it he leaves with us, when ascending from us, other than his own presence, which he never withdraws? For he himself is our peace who has made both one. It is he, therefore, who becomes our peace, both when we believe that he is and when we see him as he is. For if—so long as we are in this corruptible body that burdens the soul and are walking by faith, not by sight—he does not forsake those who are sojourning at a distance from himself, how much more, when we have attained to that sight, shall he fill us with himself?

I mean he would never separate an innocent person instead of a guilty one, or by separating the guilty forsake the innocent.… It was Judas himself who separated himself from the Lord.

[AD 444] Cyril of Alexandria on John 14:27
Herein when He reminds His holy Apostles of His ascension into heaven, and prepares them for the knowledge that they will be left thereby alone by the saying: These things have I spoken unto you while yet abiding with you, He was stricken at heart by the knowledge, being as He was by nature God, that the saying gave them no small alarm, and put them into great fear and trembling, and by laying a burden of grief upon them had stirred the mind of each to its depths. For what could be more grievous than their sorrow, and what so burdensome as to be robbed of the highest blessings and to undergo the unexpected loss of that which was most dear to them? He therefore stablishes them when they were disturbed by grief and fear. For the cause and root of their sorrow, His being about to leave them and go to His Father, was most well-grounded. But He considered their apprehension of unknown suffering as the cause of their grief, and very readily, as He Who was strong to save was no longer present, according to the actual vision of the body. And how does He stablish them, and in what way does He produce in them the brightness of a cheerful spirit, and how are their minds lulled again into a Divine calm? Peace I give unto you, He says, My peace I leave with you. I have often told you, He says, that I will not leave you desolate, nor will you dwell alone in the earth, stripped and robbed of your defender; nay, rather, I will be with you, and though absent in the flesh will again edify you by My consolations as God, and will set you above every terror, and no man shall surpass you in boldness; for all fear shall dwindle away, and cowardice shall vanish from your path, and a Divine power shall spring up in you, bringing you with peaceful mind, and heart at rest, to the revelation of those things which pass man's understanding. And now, He says, Peace I give unto you, not simply, but My peace. And this was clearly nothing else but saying: I will bring the Spirit, and of Myself will abide with those who receive Him.

For that the peace of Christ is His Spirit, it needs no long argument to completely demonstrate. But I suppose one ought to say this, if He is peace in heaven and on the earth, how can it fail to be clear to everyone, that as we have said, the peace is certainly His Spirit? And indeed the inspired Paul said to some: And the peace of God which passeth all understanding shall guard your hearts and your thoughts. And surely it is right to reflect, that it is not about that peace which has reference to common thought and action that He says this. For that disposition which loathes dispute and strife has and works peace, so far as its own waverings and inclinations will allow it. And we shall not think that the peace which is here meant is something which has not a real and independent existence; but we must suppose that it is found in the temper of those who love it. How then can one think that such a peace as this surpasses all understanding? For that which nowhere and nohow has an independent existence, how could that be thought better and nobler than men, or angels, or even higher beings? for these too we say are mind. The peace therefore that is above all principality, and power, and thrones, and sovereignties, and excels all intellectual existence, is the Spirit of Christ, by Which the Son reconciles all things to God the Father, by willing the things that are His and by wishing to think and do them, and not by being perverted or falling away through turning aside to wickedness. And it is easy and expedient to reflect on this. For just in the same way as since the Son is by nature life, and wisdom, and power, and the Spirit is called and is His, the Spirit is of life, and wisdom, and power; so since the true and sovereign peace is He Himself and no other, His Spirit might rightly be named and thought as He is----" peace." For this reason and in a special manner referring His own peace, that is to say the Spirit, to His own nature, He says concerning Him, My peace I leave with you. That also in the holy prophets the Spirit of Christ has been so named, you will easily perceive, when you hear this from the mouth of Isaiah: O Lord our God grant us peace: for Thou hast given us all things. For as the Law brought nothing to completion, and righteousness according to it did not suffice to bring men to perfect piety, He entreats that the Holy Spirit be vouchsafed, by Whom, reconciled to God the Father, we have been admitted into fellowship with Him, who have before been shown to be reprobates through the sin that reigneth in us. Grant us then peace, he says, Lord; for Thou hast given us all things. And what he wants to show, I say, is this: "Grant us too, Lord, the peace; for we shall then confess that we have all things, and no blessing will be found lacking to him that has once for all reached the fulness of Christ. For it is the completion of all good that God should dwell in us by the Spirit." For since the Spirit is fully sufficient to allay all tumult of the mind, and to dispel all cowardice in us, He promises to give us as provision by the way, that which is needful to maintain our courage and peace, when He says, My peace I leave with you: let not your heart be troubled, neither let it be fearful.
[AD 542] Caesarius of Arles on John 14:27
Peace, indeed, is serenity of mind, tranquility of soul, simplicity of heart, the bond of love, the fellowship of charity. It removes hatred, settles wars, restrains wrath, tramples on pride, loves the humble, pacifies the discordant and makes enemies agree. For it is pleasing to everyone. It does not seek what belongs to another or consider anything as its own. It teaches people to love because it does not know how to get angry, or to extol itself or become inflated with pride. It is meek and humble to everyone, possessing rest and tranquility within itself. When the peace of Christ is exercised by a Christian, it is brought to perfection by Christ. If anyone loves it, he will be an heir of God, while anyone who despises it rebels against Christ. When our Lord Jesus Christ was returning to the Father, he left his peace to his followers as their inherited good, teaching them and saying, “My peace I give to you, my peace I leave with you.” Anyone who has received this peace should keep it, and one who has destroyed it should look for it, while anyone who has lost it should seek it. For if anyone is not found with it, he will be disinherited by the Father and deprived of his inheritance.

In Genesis: "Then said the Lord to Adam, Because thou hast hearkened to the voice of thy wife, and hast eaten of that tree of which alone I commanded thee that thou shouldest not eat, cursed shall be the ground in all thy works; in sadness and groaning shalt thou eat of it all the days of thy life: thorns and thistles shall it cast forth to thee; and thou shalt eat the herb of the field in the sweat of thy brow. Thou shall eat thy bread until thou return unto the earth from which also thou wast taken; because earth thou art, and to earth thou shall go." Also in the same place: "And Enoch pleased God, and was not found afterwards: because God translated him." And in Isaiah: "All flesh is grass, and all the glory of it as the flower of grass. The grass withered, and the flower hath fallen away; but the word of the Lord abideth for ever." In Ezekiel: "They say, Our bones are become dry, our hope hath perished: we have expired. Therefore prophesy, and say, Thus saith the Lord, Behold, I open your monuments, and I will bring you forth from your monuments, and I will bring you into the land of Israel; and I will put my Spirit upon you, and ye shall live; and I will place you into your land: and ye shall know that I the Lord have spoken, and will do it, saith the Lord." Also in the Wisdom of Solomon: "He was taken away, lest wickedness should change his understanding; for his soul was pleasing to God." Also in the eighty-third Psalm: "How beloved are thy dwellings, Thou Lord of hosts? My soul desires and hastes to the courts of God." And in the Epistle of Paul to the Thessalonians: "But we would not that you should be ignorant, brethren, concerning those who sleep, that ye sorrow not as others which have no hope. For if we believe that Jesus died and rose again, so also them which have fallen asleep in Jesus will God bring with Him." Also in the first Epistle to the Corinthians: "Thou fool, that which thou sowest is not quickened except it have first died." And again: "Star differeth from star in glory: so also the resurrection. The body is sown in corruption, it rises without corruption; it is sown in ignominy, it rises again in glory; it is sown in weakness, it rises again in power; it is sown an animal body, it rises again a spiritual body." And again: "For this corruptible must put on incorruption, and this mortal put on immortality. But when this corruptible shall have put on incorruption, and this mortal shall have put on immortality, then shall come to pass the word that is written, Death is absorbed Into striving. Where, O death, is thy sting? Where, O death, is thy striving?

We confess that the only-begotten God, while he abode in the form of God, abode in the nature of God, but we do not at once reabsorb into the substance of the divine unity his unity bearing the form of a servant. Nor do we teach that the Father is in the Son, as if he entered into him bodily.… God, born of God, being found as man in the form of a servant but acting as God in his miracles, was at once God as his deeds proved, and yet man, for he was found in the fashion of man.

The Father is greater, for the Son prays to him to render glory to the manhood he has assumed. The Son is not less, for he receives back his glory with the Father. Thus are consummated at once the mystery of the birth and the dispensation of the incarnation. The Father, as Father—and as glorifying him who now is Son of man—is greater. Father and Son are one in that the Son, born of the Father, after assuming an earthly body is taken back to the glory of the Father.

[AD 379] Basil of Caesarea on John 14:28
“Greater” is used when talking about size, time, dignity, power, or the cause of something. The Father cannot be called greater than the Son in size because he is incorporeal. He cannot be called greater than the Son in time because the Son is the creator of time. You can’t say that he is greater in dignity either, because he was not made into something that he had not previously been, nor can you say he is greater in power since, “whatever the Father does, the Son does as well.” And finally, no one can say the Father is greater because he is the cause of the Son’s existence, because he is also the cause of our existence, and this would place the Son on a similar footing with us. Instead, see the words as expressing the honor that is given by the Son to the Father instead of devaluing the Son who speaks these words. You should also realize that what is greater is not necessarily of a different essence. One human being is called greater than another human being, just like one horse is called greater than another horse. If the Father is called greater, it does not immediately follow that he is of another substance. In a word, the comparison lies between beings of one substance, not between those of different substances. A human being is not properly said to be greater than a brute or an inanimate thing. Human beings are compared to human beings, just as brutes are compared with other brutes. The Father is therefore of one substance with the Son, even though he is called greater.

[AD 398] Didymus the Blind on John 14:28
How then is “greater” to be understood? Does it pertain to the size of bodies? Or does it mean “more advanced” in age? Or does it mean “adorned with more virtue”? But all these things can be quantified—whatever can be perceived and measured. But in God there is nothing that can be perceived or measured. Thus, the words greater and less cannot be spoken concerning the Word of God or concerning the Father. For by nature God cannot be measured or quantified. But if you say that the Father is greater since he is unbegotten while the Son is begotten, we reply that these words speak of their natures, not of their properties of existence. And especially in the cases of those incorporeal beings one does not diminish the value of those of the same substance by granting more or less to this one or to that one. For by nature Absolute Being cannot be measured in essence or in knowledge simply by any measure or quantity of size. Then why did [Christ] say these things?The Savior in one word set forth a double manner of teaching, for the meaning of the word he spoke is twofold. It is just as in the phrases “the one sending me” and “I depart”: he alluded to the body embraced by definite locations, inasmuch as it is circumscribed by them, and he did not refer to the uncircumscribed divine nature that embraces all things. By analogy, then, when he says “greater,” he indicates that his divinity can be equaled to that of the Father, since he is of the same substance with him, but the Father is greater because the Son accepted a body, since the Son’s nature is understood to be less than that of the Father inasmuch as the Son has become man. And do not marvel that the Savior says that he is less than the Father since he became man, since he also has said that he became lower than the angels, as in this verse: “We see Jesus made lower than the angels for a little time because of the suffering of his death, but now crowned with glory and honor.” He was also said to be lower than his own disciples, for he said, “I am in your midst as your servant” and as the least. Therefore, things that are compared share the same substance, but things that are undivided (whether in our knowledge or by their essence) cannot admit of “greater” and “less.” Now if you wish to understand the sentence, “The Father who sent me is greater than me,” to apply to the divinity of the Son apart from considering that he has taken on flesh, you will have to suppose that he is enclosed in and restricted to certain places and that he was sent where he had not previously been and removed from where he had been. But this makes no sense.

Let us, along with the disciples, listen to the Teacher’s words, and not, with strangers, give heed to the wiles of the deceiver. Let us acknowledge the twofold substance of Christ, namely, the divine, in which he is equal with the Father, and the human, in respect to which the Father is greater. And yet at the same time both are not two, for Christ is one. And God is not a quaternity but a Trinity. For as the rational soul and the body form but one man, so Christ, while both God and man, is one. Thus Christ is God, a rational soul and a body. In all of these we confess him to be Christ. We confess him in each. Who, then, is he who made the world? Christ Jesus, but in the form of God. Who is it that was crucified under Pontius Pilate? Christ Jesus, but in the form of a servant. And this is true of the several aspects of which he consists as man. Who is he who was not left in hell? Christ Jesus, but only in respect of his soul. Who was to rise on the third day, after being laid in the tomb? Christ Jesus, but solely in reference to his flesh. In reference, then, to each of these, he is likewise called Christ. And yet, all of them are not two or three but one Christ. On this account, therefore, he said, “If you loved me, you would surely rejoice, because I go to the Father.” For human nature is worthy of congratulation in being so assumed by the only-begotten Word as to be constituted immortal in heaven and, earthly in its nature, to be so sublimated and exalted that, as incorruptible dust, it might take its seat at the right hand of the Father.

[AD 444] Cyril of Alexandria on John 14:28
If ye loved Me, ye would have rejoiced, because I go unto the Father; for My Father is greater than I.

CHAPTER I. That in nothing is the Son inferior to God the Father, but rather equal to and like Him in nature.

He turns the occasion of sorrow into a source of solace, and plainly rebukes them because they do not rather rejoice at what now gives them pain: and at the same time tries to teach them, that those who practise an unaffected and sincere love towards others, must not merely seek their own pleasure and advantage, but rather to benefit those they love, when an opportunity to do this gives them inducement. Therefore also Paul exhorts us in the words: Love vaunteth not itself, is not puffed up, doth not behave itself unseemly, seeketh not its own. He speaks of some who seek not their own but others' good. For true love shows itself in our not only providing for our own advantage but also considering our neighbour's benefit. For our Saviour, in the words before us, persuades His disciples to lay this to heart. And, further, let us imprint the power of this thought in clearer characters on our hearts as on a tablet, and thereby attain unto the mystery of Christ. For a type taken from trifling things will oftentimes avail to enable us to arrive even at those things which we hold to admit of no comparison. It was pleasant then, for example, to the disciples of Paul that they should be always with him, but better for Paul to depart and be with Christ, as he has assured us by his own words. It was the duty then of those who chose to love him to be eager to fulfil their love towards him, and not to consider that only as endurable which was pleasant to themselves, but rather to reflect upon this, that his departure would be to the benefit of their master; for he was eager to be with Christ.

You have the outline of the speculation so far as concerns Christ's human nature. Let us therefore, illuminating as it were with varied tints our sketch of the power of the mystery of Christ, clearly show the absolute truth. For the Only-begotten, being in the form of God the Father, and in equality with the Spirit, counted it not a prize to be on an equality with God, and through His love towards us emptied Himself of His glory, taking the form of a servant, and underwent this that He might direct us all to perfect knowledge of virtue, so as to prepare us by the incomparable brightness of His miracles to behold the power, and glory, and exceeding might that is inherent in the Divine Nature. For so He might have induced those who have fallen into the depths of ignorance to recover knowledge once more, and no longer to worship the creature beyond the Creator, but to figure to themselves the One true and living God. And the Only-begotten has aided us in other ways by His incarnation, for He destroyed the power of death, and loosed the bonds of sin, and granted us to tread upon serpents and scorpions, and over all the power of the enemy. It was then, and with great reason, sweet and pleasant beyond all description to ourselves and the holy disciples, to have continual converse with Christ the Giver of such blessings to us, and to be ever present with Him and in His company. But it was clearly not to His advantage, so long a time to choose to abide in the guise of humility, which He had taken for our advantage, through His love to us, as we just now said: rather was He bound, when His dispensation towards us had been already suitably accomplished, to ascend to His own glory, and, with the flesh that He had taken for our sake, to hasten back to equality with God the Father, which thinking it not robbery to do (for He might have had this honour in His own right), He descended to human humiliation. For while He was yet upon the earth, though He was truly God and Lord of all, He was thought no better than the rest of men, by those who knew not His glory. Nay, more, He was smitten, and spat upon, and crucified, and underwent the ridicule of the impious Jews, who dared to say, If Thou art the Son of God, come down now from the cross, and we will believe Thee. And when after He had fulfilled the mystery of our redemption, He ascended to God the Father in the heavens, when the time of His humiliation was already past, and the period of His voluntary degradation accomplished, He showed Himself very God to the powers above. For heaven did not deny the Lord of all when He ascended, but the charge was given to the sentinels at the gates above, that the Lord of Hosts was drawing nigh, although He was borne upward in the raiment of the flesh; and the Spirit was representing the opening of the gates, when He said: Lift up the gates ye rulers, and be lifted up ye everlasting doors, and the King of Glory shall come in. The Lord strong and mighty, the Lord mighty in battle, the Lord of Hosts, He is the King of Glory. For the manifold wisdom of God which He purposed in Christ was known unto the principalities and the powers, as Paul says. For when He ascended to the Father, although He may be thought greater than the Son in this respect, that He remained in His everlasting home, while the Son underwent voluntary humiliation, and descended in the form of a servant, and ascended up again to His own glory, and heard the words: Sit down on My right hand until I make Thine enemies Thy footstool. And it was to the intent that He might not seem too presumptuous, and that God the Father in the heavens had not of His own will made the Son sit on His right hand, the Father Himself is introduced saying this: Sit Thou on My right hand, the Psalmist says this. And no one with any sense will say that the Father has the second place of honour though He has the Son on His right hand, but will rather take what I have said into consideration. For it is not the Father, but rather the Son, on account of His voluntary degradation and suffering, Who must be conceived as sitting on the right hand, and having a place from which no inferiority could be inferred, as He might be numbered among inferior beings by those who cannot comprehend the mystery of His Incarnation. Therefore a place on the right hand of His Father, against Whom no such charge can be brought, is allotted to the Son that His equality may be maintained.

We have done well to introduce these explanations now, which have an intimate connection with the present subject. Now taking up again and unfolding from the beginning the whole purpose of our disquisition, I proceed to say that continual converse with our Saviour Christ is sweet and acceptable and pleasant to us, although for our sake He has emptied Himself of His glory, as has been written, and taken the form of a servant and the dishonour of man's nature. For what is man's nature as compared with God! Nor was the Incarnation to the advantage of the Son, but to ascend to His Father profited Him more, and to recover His own glory and power and Divine honour in the sight of all, and no longer obscured. For He sat on the right hand by the will of His Father. For He loves Him as His own Offspring and the fruit of His Substance, and therefore He says, If ye loved Me, ye would have rejoiced because I go unto the Father: for the Father is greater than I. Surely it was a proof of His Father's love towards Him that He did not sorrow over His seeming abandonment and the compulsory absence that He had taken on Himself, but rather took into consideration that He went to the glory befitting Him, and His due, and to His ancient honour, that is the Godhead manifest. Nay more, the Psalmist, though he speaks mysteries by the Spirit, says, Clap your hands, all ye people: then he explained the occasion of the festival, and introduced the Ascension of the Saviour into heaven, saying, God is gone up with a shout, the Lord with the sound of a trump: meaning by the shout and the trump the piercing and clear voice of the Spirit, when He bade the powers above open the gates, and named Him Lord of Hosts, as we said just now. On the same occasion moreover, we shall find the choir of the Saints rejoicing with great joy of heart. Then too he said in one place, The Lord reigneth, let the earth rejoice; and in another, The Lord reigneth: the Lord hath put on glorious apparel, the Lord hath put on and girded Himself with might. For He that was with us as a man before His resurrection from the dead, when He ascended to His Father in the heavens, then put on His own glorious apparel, and girded Himself with the might that was His from the beginning, for He sat and reigneth with the Father. Then it is right and meet that those who love Him should rejoice because He has gone to His Father in the heavens, to take upon Him His own glory, and to reign again with Him as at the beginning. And He says that He is greater, not because He sat down on the right hand as God, but as He was still with us, that is, in human shape. For as He still wore the guise of a servant, and the time had not yet come that He should be reinstated, He calls God the Father greater. Moreover, when He endured the precious cross for us, the Jews brought Him vinegar and gall when He was athirst, and when He drank, He said, It is finished. For already the time of His humiliation was fulfilled, and He was crucified as man. He had overcome the power of death, not as man but rather as God, I say by the working of His power and the glory and might of His conquest, not according to the flesh. The Father then is greater since the Son was still a servant and in the world, as He says that He is God of Himself, and adds this attribute to His human form. For if we believe that He degraded and humbled Himself, will it not be obvious to all that He descended from superiority to an inferiority, and rather from equality with the Father to the reverse. The Father underwent nothing of this, and He abode where He was at the beginning. He is greater therefore than He that chose inferiority by His own dispensation, and remained in such a state until He was restored to His ancient condition, I mean His own and natural glory in which He was at the beginning. We may rightly judge that His equality with the Father, which while He might have had it uninterruptedly He did not consider robbery to take for our sake, is His own and natural position.

And as we have spoken at length about the equality of the Son with God the Father in previous books, it may well be fitting to proceed to illustrate all things in order, leaving long discussions on the subject for the present. And since a certain dull-witted heretic, receiving from the Jews some marvellous knowledge of the holy writings, and attempting to explain the verse we have before us, has committed to writing intolerable blasphemies against the Only-begotten, I deemed it a mark of feebleness, and very unbecoming to myself, calmly to pass them by, and to dismiss in silence the awful madness of the man to whom I allude. I think then we ought to encounter him in argument, and show that his words are baseless and old wives' fables, and wholly devoid of sense, and the quibbles of a perverted logic. And with reference to the same passage, I will read over to you what he has dared to write when giving the view he took of the text: "When He called His Father greater than Himself, He not only displayed His own humility but also refuted the heresy of those who maintain that His nature is twofold." And having thus shattered the opinion of Sabellius, he makes a furious and vigorous onslaught, as he thinks, on those who put the Son on an equality with the Father in these words: "Some have reached such a pitch of madness that they cannot at all endure to say that the Father is superior to the divinity of the Only-begotten, but only that the Father seems to surpass Him when compared with Him in reference to the Incarnation, though they are not even able to look at them together in this aspect; and things different in kind can in no way be compared. For no one would ever say that man is wiser than a beast, or that a horse runs faster than a tortoise; but that one man has more reason than another, and that one horse has greater speed than another. Since then only things belonging to the same class are capable of comparison with each other, we must admit that the Father is greater even than the divinity of the Son. For those who fall into the contrary error of drawing a comparison with reference to the Incarnation, so far as in them lies, lessen the honour of the Father."

Such are his puerile babblings. And we must take care to show that he does not even know that he is inconsistent with himself. For he admits that the Son maintains becoming humility, when He says, The Father is greater than I; and I marvel that he did not also lay this to heart. For whatever was it which induced him to meddle with theology, although one would not make of no account the knowledge of the fitting time to speak or act if one were wise? What need was there then of such unseasonable discussion of the Divine Nature to His disciples in their agony, when He was about to depart from the world to God the Father? For what kind of consolation could this consideration bring to them? And why does not He merely rebuke them, saying, "If you loved Me, you would rejoice that I go to the Father, because the Father is greater than I?" Tell me then, did He think that this tended to solace the disciples, or to rid them of the sorrow they felt from their love of God, that He was going to the Father Who was greater than Himself? Although when Philip asked Him and said, Lord, show us the Father, and it sufficeth us, then indeed, and very opportunely, as the occasion for theological teaching had arrived, He showed that the Father was in Him, and He Himself in the Father, and that He was in no way inferior to Him, but distinguished by His perfect equality, when He said: Have I been so long time with you, and dost thou not know Me, Philip? He that hath seen Me hath seen the Father. Believest thou not that I am in the Father, and the Father in Me? I and the Father are one. Then indeed, very opportunely, He unravels His discourse thereupon, and it is worthy of admiration. But here, how is the reference opportune? Or what construction would it admit of other than His desire to allay His disciples' grief, and to furnish them, as it were, with a medicine of consolation bidding them rejoice because He "goes to the Father?" Is it not then obvious to any one, however dull-witted he may be, from the very state of the case, that since He was hastening to return to His own glory with the Father, He bade those who loved Him rejoice at this, devising this admirable means of consolation for them with the rest?

But I will now pass this by, and will not lay much stress on their demented folly. But I say that we ought rather to go on to the following considerations. For He thought perhaps when comparing His Incarnate Nature with His Divine, they could not help making profit out of the inquiry, when we say that the Son was emptied of His glory when He became a Man. Is it not so? How could it be otherwise? But speaking of His Divine glory, in contrast with His place as a servant, and His position of subjection, we say that the Son was inferior to the Father, in so far as He was human; but that He was reinstated into His equality with the Father after His sojourn here, not endued with any new, or adventitious, or unaccustomed glory, but rather restored to that state in which He was at the beginning with the Father. And indeed, the inspired writer who initiates us into mysteries, I mean Paul, no longer attributing to Him the humiliation belonging to man's estate after His resurrection from the dead and ascension into heaven, exhorts us saying: Even though we have known Christ after the flesh, yet now we know Him so no more. And of himself again: Paul, an apostle of Jesus Christ, not from men, neither through man, but through Jesus Christ. And yet, why is it that when He says that on His second coming to us He will change the body of our humiliation, that it may be conformed to the body of His glory, he now denies it, saying: Not from men, neither through man, although destined to be an apostle by Jesus Christ? But how is it that he says he knew Him not in the flesh? Did he then, tell me, deny the Master that bought him? God forbid; for he is rightminded. For when the period of the actual humiliation or degradation of the Only-begotten had been accomplished, and come to an end, He makes haste to proclaim Himself and to gain recognition, not in the character which He presented when emptied of His glory, but of His natural attributes of God. For when it had once been known and admitted that He was human, He was bound to instruct believers in Him that He was also God by nature; and for this reason He chooses to speak of His divinity, rather than anything else.

And I marvel that the heretic of whom we are speaking does not blush when he says that "as only things which belong to the same class admit of comparison with each other, they must confess the Father is greater than the Divinity of the Son." For he does not perceive, it seems, that he has armed his own argument against himself. For let him answer us this pertinent inquiry: From what starting point can comparisons of things of the same class best proceed? Can we reasonably start with what they are, according to the common definition of their nature, or with the qualities which belong to, or are deficient in each, or inhere or do not inhere in each? And I will give an example, and will select that which he gave to us by way of illustration. If any one choose to compare one man with another, looking to the one common definition of their essence, he would find no distinction; for there is no difference between man and man, so far as each is a thinking animal, mortal, and capable of sense and knowledge, as in all men there is one and the same definition of their essence. Nor does one horse differ from another in its essential character as a horse; but one man differs from another in some special sort of knowledge, as writing, and in divers other ways. This does not affect the essence, but clearly proceeds from quite another cause. So also one horse excels another in speed, or is smaller or larger than another; but you will find that superiority or inferiority in these respects lies outside the definition of their essence, otherwise things brought into mutual comparison could have no distinctions made between them. For if one man had a less or greater degree of the essential character of man, how could we conceive or speak of him at all? Then all things of the same type in their essential characters are uniform. But the difference lies in those attributes which either inhere in them, or which lie outside (viewing them in the light of accidents). Since then, according to his premise or statement, which I will proceed to deal with, only things of like nature admit of comparison at all appropriately, he must start by admitting that the Son is of the same class as the Father, that is, of the same Essence. For so you will have the same class in view; for he proved that man might be compared with man, and horse with horse. Then let him go on to tell us the reason why, when the Son is compared with God the Father as being of the same class He has any kind of inferiority to Him, and where we shall find it, when one and the same definition of their essence belongs to things of the same class? For in the case of the essence of a class, its definition is not perfect in some cases and imperfect in others, but is one and the same for all. But we may say that any accident may have a separate cause and accrue to a thing in a different manner.

In order to make what I have said quite clear, I will set before you the illustration I gave at the outset. No man differs from another in his essential character as man; but one man is pious and another wicked; and one is weak and maimed, while another is healthy and strong; and one is vile and another good. But when a man accurately investigates the reasons for these distinctions, he will not trace them to their common definition of the essence, but rather attributes the causes to diseases of mind or body. As then, there is one definition of Godhead for the Father and the Son both in conception and reality (otherwise one could not but go astray), for They are compared as belonging to the same class, and I will use his words for the purpose of the argument----let these deluded men tell us what they think it was that paved the way for the inferiority of the Son to God the Father; was it disease, or indolence, and those things which are known to affect created beings'? Who would be so mad and such a slave of contradictions as even to lend an ear to such blasphemy? When then, being (as He is), of the same class as the living God, He Himself also is manifestly by nature God----for He is brought into comparison with the Father: and nothing can hinder His having a like state with His Father----how is He inferior?

Since, then, this adversary of the truth has given in detail a mass of contradictions, with reference to the text, and has not hesitated to affirm that "the Father is greater than the Godhead of the Son," let us then, after having made a brief defence of the Incarnation, and separated it in our demonstration from the consideration of the matter under discussion, compare the Divinity of the Son with that of the Father, according to Their definition; but let us previously inquire of him who dares to say this, whether he thinks that God, when He is God, is so by nature, or something else besides, but honoured with the appellation of Divinity, as there are many so that are called gods and lords in heaven, and many on earth. When then he asserts that the Son has been honoured by the bare appellation of Divinity, but that He is not by nature really that which He is said to be, we who are rightminded will encounter him, and openly exclaim, "My good Sir, if He is not really God, we shall worship the creature in preference to the Creator, and not only we who inhabit this earthly sphere, but also the multitude of holy angels; and we shall also accuse every Saint who has spoken of Him as the real and true God, and most of all we charge S. John, who said of Him: We know that the Son of God is come, and hath given us an understanding, that we may know the true God, and we are in His true Son Jesus Christ: this is the true God, and eternal life." But if, rejecting all inspired writings alike, he confess that He is really God, and be so minded and still suggest the doctrine that even so He falls below the Father's dignity in some respect, has he not introduced to us a new God, wholly dissevered from His natural connection with the Father, and conceived of as having a separate existence and not inhering in the substance of God the Father? But I think the matter is obvious to every one. For if nothing is conceived of as being greater or less than itself, but as greater than anything which is less, and less than anything which is greater, must he not perforce admit that there are two true and real Gods, so that one is thought the greater, and the other the less. So the faith of the Church is wholly destroyed and overturned by their doctrine, for we shall have not one God but two. Whose temples then are we according to the Scriptures? Surely His Who established His Spirit in our hearts. When then we find in the Holy Writings the Spirit spoken of as not of the Father only but also of the Son, what are we to infer, and what view must we take? Which of the two reject and call the other God? If, however, we are to admit a duality of Gods, one less and the other greater, we shall say that both abide in our hearts by separate Spirits, and we shall be found temples of more than one God, and there are two Spirits dwelling in us, a greater and a less, corresponding to the nature of those who gave them. For who could tolerate such ravings, and who cannot see that their doctrine is absurd and ridiculous, after he has considered the view I have just set forth? But, perhaps, if he is forced to admit that there is a duality of Gods by nature, one the greater and the other the less, he will proceed to that doctrine that is always recurring in his writings; I mean, he will say that the Son has a separate nature----though He is not wholly devoid of the nature of a created being, yet neither does He wholly decline from the Divinity of God the Father. For those who do not scruple to say plainly that He is a creature take refuge in refinements of language, trying as it were to gloss over their profanity. When then we say that the Son has such a nature as not to be wholly God, nor yet to fall entirely into the category of creatures, but that He holds an intermediate place, so as to fall beneath the dignity of God the Father, and yet to exceed created beings in glory, we will say first of all, that there is no authority to induce us to lay down the doctrine they choose to propound. For either let them satisfy us from the holy and inspired writings, or confessing they have no voucher for their private opinion, blush for laying down definitions in matters of faith from their own private judgment.

But since it occurred to them to say this in their rash folly, I will proceed to the view they have propounded, and I will say once more that if only things of the same class are properly capable of mutual comparison,----and the Son has proved that He may properly be compared with God the Father in the plainest language, The Father is greater than I,----must not then the Father be conceived of as having the same nature you attribute to the Son? What follows then? Your whole speculation is upset. For so long as you maintain that the Father is greater than the Son, but a created being is less according to you, the nature of the Only-begotten lies between the two. And when the nature of the Father is lessened to that of the Son, one of the extremes is left out, as there is no longer anything above and superior to the Son. And if, as he says, He is compared with the Father as being one of the same class, must not the definition of Their Essence be one and the same for both? And if you scruple to admit that the Son is of the same Essence with the Father, but rather put Him in a position of inferiority, and debase the glory of the Father to that of a being whom you reckon less than and inferior to Him, do you not see blasphemy springing up like a thorn? Does not then a root of bitterness springing up rankle in the heart of those thus minded? Why then do you leave the straight path of truth, and launch into such absurd discussions? Grant then to the Only-begotten in your thoughts an equality with God the Father. For thus there will be One God, worshipped and glorified in the holy and consubstantial Trinity, both by us and by the holy angels.
[AD 444] Cyril of Alexandria on John 14:28
You learnt, He says, from no other lips than Mine My departure hence, for you heard My sayings with your own ears, and what have I, Who cannot lie, promised unto you? I go away, and I come unto you. If then His words had threatened that His departure would leave them comfortless, and that their bereavement would be eternal, it was very likely that they would thereupon be dreadfully dismayed, and find it unbearable, and fall into excess of despondency. And whereas I said unto you not simply that I would go away, but that I would come again in due season, why then, He says, do you let into your hearts only the cause of grief, and slight by your forgetfulness that which is able to cheer. Let that which knows how to succour arise in you to combat that which affrights: and let the power of the Comforter wrestle with the incitements to grief. For it has been ordained that I should ascend to God the Father, but I have promised to come again. He allays then the agony of grief He found in His disciples; and just as a fond and good father, compelled for some needful purpose to take his children from the nurse that bears them, and seeing a flood of tears bedewing their delicate and dear cheeks, he tries every blandishment, and by always insisting on the good that will result from her absence, arms in some sort hope against grief, where the affections are most nearly concerned; so also our Lord Jesus Christ shields the souls of His Saints from sorrow. For He knew, being truly God, that His abandonment of them would be very grievous unto them, although He were ever with them by the Spirit. And this proves His love and extreme holiness. For to wish to be with Christ, how does not that most truly become the Saints? And of a truth the admirable Paul has this aim in view when he says: It is better to depart and be with Christ
[AD 444] Cyril of Alexandria on John 14:28
Jesus soothes the agony of grief he found in his disciples, and just as a beloved and good father, compelled for some legitimate reason to take his children from the nurse that bears them, and seeing a flood of tears flowing down their delicate cheeks, he coaxes them by insisting on the good that will result from her absence and arms them against grief with hope. So also our Lord Jesus Christ shields the souls of his saints from sorrow. For he knew, being truly God, that his abandonment of them would be hard for them to take, even though he would always be with them through the Spirit. This proves his love and extreme holiness.

Sometimes, therefore, I [Jesus] say that I am equal to the Father, and at other times I say that the Father is greater. I am not contradicting myself, but I am showing that I am God and a human being—God through the lofty words, and a human being through the humble ones. But if you want to know how the Father is greater than I, I was talking from the flesh, not from the person of the divinity.

If we say that the Father is the origin of the Son and greater than the Son, we do not suggest any precedence in time or superiority in nature of the Father over the Son (for through his agency he made the ages) or superiority in any other respect except causation. And we mean by this that the Son is begotten of the Father and not the Father of the Son, and the Father naturally is the cause of the Son. So then, whenever we hear it said that the Father is the origin of the Son and greater than the Son, let us understand it to mean in respect of causation.

[AD 407] John Chrysostom on John 14:29
As though He had said, You would not have known, had I not told you. And I should not have told you, had I not been confident. Do you see that the speech is one of condescension? For when He says, Think ye that I cannot pray to the Father, and He shall presently give Me more than twelve legions of Angels Matthew 26:53, He speaks to the secret thoughts of the hearers; since no one, even in the height of madness, would say that He was not able to help Himself, but needed Angels; but because they thought of Him as a man, therefore He spoke of twelve legions of Angels. Yet in truth He did but ask those who came to take Him a question, and cast them backwards. John 18:6 (If any one say that the Father is greater, inasmuch as He is the cause of the Son, we will not contradict this. But this does not by any means make the Son to be of a different Essence.) But what He says, is of this kind: As long as I am here, it is natural that you should deem that I am in danger; but when I have gone 'there,' be confident that I am in safety; for Him none will be able to overcome. All these words were addressed to the weakness of the disciples, for, I Myself am confident, and care not for death. On this account, He said, I have told you these things before they come to pass; but since, He says, you are not yet able to receive the saying concerning them, I bring you comfort even from the Father, whom you entitle great. Having thus consoled them, He again tells them sorrowful things,
[AD 430] Augustine of Hippo on John 14:29
1. Our Lord and Saviour, Jesus Christ, had said unto His disciples, If you loved me, you would surely rejoice, because I go unto the Father; for the Father is greater than I. And that He so spoke in His servant-form, and not in that of God, wherein He is equal with the Father, is well known to faith as it resides in the minds of the pious, not as it is feigned by the scornful and senseless. And then He added, And now I have told you before it come to pass, that, when it has come to pass, you might believe. What can He mean by this, when the fact rather is, that a man ought, before it comes to pass, to believe that which demands his belief? For it forms the very encomium of faith when that which is believed is not seen. For what greatness is there in believing what is seen, as in those words of the same Lord, when, in reproving a disciple, He said, Because you have seen, you have believed; blessed are they that see not, and yet believe. And I hardly know whether any one can be said to believe what he sees; for this same faith is thus defined in the epistle addressed to the Hebrews: Now faith is the substance of those that hope, the assurance of things not seen. Accordingly, if faith is in things that are believed, and that, too, in things which are not seen, what mean these words of the Lord, And now I have told you before it come to pass, that, when it has come to pass, you might believe? Ought He not rather to have said, And now I have told you before it come to pass, that you may believe what, when it has come to pass, you shall see? For even he who was told, Because you have seen, you have believed, did not believe only what he saw; but he saw one thing, and believed another: for he saw Him as man, and believed Him to be God. He perceived and touched the living flesh, which he had seen in the act of dying, and he believed in the Deity infolded in that flesh. And so he believed with the mind what he did not see, by the help of that which was apparent to his bodily senses. But though we may be said to believe what we see, just as every one says that he believes his own eyes, yet that is not to be mistaken for the faith which is built up by God in our souls; but from things that are seen, we are brought to believe in those which are invisible. Wherefore, beloved, in the passage before us, when our Lord says, And now I have told you before it come to pass, that, when it has come to pass, you might believe; by the words, when it has come to pass, He certainly means, that they would yet see Him after His death, alive, and ascending to His Father; at the sight of which they should then be compelled to believe that He was indeed the Christ, the Son of the living God, seeing He could do such a thing, even after predicting it, and also could predict it before He did it: and this they should then believe, not with a new, but with an augmented faith; or at least [with a faith] that had been impaired by His death, and was now repaired by His resurrection. For it was not that they had not previously also believed Him to be the Son of God, but when His own predictions were actually fulfilled in Him, that faith, which was still weak at the time of His here speaking to them, and at the time of His death almost ceased to exist, sprang up again into new life and increased vigor.

2. But what says He next? Hereafter I will not talk much with you; for the prince of this world comes; and who is that, but the devil? And has nothing in me; that is to say, no sin at all. For by such words He points to the devil, as the prince, not of His creatures, but of sinners, whom He here designates by the name of this world. And as often as the name of the world is used in a bad sense, He is pointing only to the lovers of such a world; of whom it is elsewhere recorded, Whosoever will be a friend of this world, becomes the enemy of God. James 4:4 Far be it from us, then, so to understand the devil as prince of the world, as if he wielded the government of the whole world, that is, of heaven and earth, and all that is in them; of which sort of world it was said, when we were lecturing on Christ the Word, And the world was made by Him. The whole world therefore, from the highest heavens to the lowest earth, is subject to the Creator, not to the deserter; to the Redeemer, not to the destroyer; to the Deliverer, not to the enslaver; to the Teacher, not to the deceiver. And in what sense the devil is to be understood as the prince of the world, is still more clearly unfolded by the Apostle Paul, who, after saying, We wrestle not against flesh and blood, that is, against men, went on to say, but against principalities and powers, and the world rulers of this darkness. For in the very next word he has explained what he meant by world, when he added, of this darkness; so that no one, by the name of the world, should understand the whole creation, of which in no sense are fallen angels the rulers. Of this darkness, he says, that is, of the lovers of this world: of whom, nevertheless, there were some elected, not from any deserving of their own, but by the grace of God, to whom he says, You were sometimes darkness; but now are you light in the Lord. Ephesians 5:8 For all have been under the rulers of this darkness, that is, [under the rulers] of wicked men, or darkness, as it were, in subjection to darkness: but thanks be to God, who has delivered us, says the same apostle, from the power of darkness, and has translated us into the kingdom of the Son of His love. Colossians 1:12-13 And in Him the prince of this world, that is, of this darkness, had nothing; for neither did He come with sin as God, nor had His flesh any hereditary taint of sin in its procreation by the Virgin. And, as if it were said to Him, Why, then, dost Thou die, if You have no sin to merit the punishment of death? He immediately added, But that the world may know that I love the Father, and as the Father gave me commandment, even so I do: arise, let us go hence. For He was sitting at table with those who were similarly occupied. But let us go, He said, and whither, but to the place where He, who had nothing in Him deserving of death, was to be delivered up to death? But He had the Father's commandment to die, as the very One of whom it had been foretold, Then I paid for that which I took not away; and so appointed to pay death to the full, while owing it nothing, and to redeem us from the death that was our due. For Adam had seized on sin as a prey, when, deceived, he presumptuously stretched forth his hand to the tree, and attempted to invade the incommunicable name of that Godhead which was disallowed him, and with which the Son of God was endowed by nature, and not by robbery.
[AD 430] Augustine of Hippo on John 14:29
If faith is in things that are believed and in things that are not seen, what does our Lord mean when he says, “And now I have told you before it happens, so that when it does happen you might believe”? Shouldn’t he rather have said, And now I have told you before it happens so that you may believe what you shall see when it happens? For even [Thomas], who was told, “Because you have seen, you have believed,” did not believe only what he saw. But he saw one thing and believed another. For he saw [Jesus] as man and believed him to be God.… But though we may be said to believe what we see, just as everyone says that he believes his own eyes, yet that is not to be mistaken for the faith that is built up by God in our souls. Rather, from things that are seen, we are brought to believe in those that are invisible. Wherefore, beloved, in the passage before us, when our Lord says, “And now I have told you before it happens, that when it happens you might believe,” by the words “when it happens” he certainly means that they would yet see him after his death, alive and ascending to his Father. And when they saw this, they would then be compelled to believe that he was indeed the Christ, the Son of the living God, seeing he could do such a thing even after predicting it and also could predict it before he did it. And this then they would believe, not with a new but with an increased faith—or at least [with a faith] that had been impaired by his death and was now repaired by his resurrection.

[AD 444] Cyril of Alexandria on John 14:29
A prophecy of the future is manifestly a sure pledge of what the future has in store for us. Christ confirms therefore the heart of His disciples, and seems to inspire in them a firm conviction that He is really ascending to God the Father in the heavens, to reign with Him and share His throne as God, and as God really begotten of Him. For do not, He says, set My departure, which is according to the flesh and an object of sight (for I will be with you as God for ever), on a level with that of the holy prophets. For they, as they passed from the earth and paid the debt of nature, were brought low, and died according to the law of human creatures. But I, Who am the true God, am not measured by the same standard as My creatures awaiting the time of the resurrection. For I live for ever, and I am the True Life. And I will send the Comforter, and I will grant you My peace also, and will not lie; but to the intent that, when you: receive the promise and are illumined by the grace of the Holy Spirit, you may ratify the truth of My words, recollecting what I have said in the light of experience, and to the intent that you may have the firm conviction that I live and reign with the Father, I have foretold and spoken this to you. The fulfilment of the promise will then confirm the truth of My words. For if I be not the Life, He says, and if I be not enthroned with God the Father, how can I Myself vouchsafe Divine and spiritual graces? And I will bestow them as I have promised, and I will bring to you the Spirit and peace. Is it not then beyond dispute that I am the Life, and that I reign with the Father. For it is not the act of one who is dead, or powerless to illumine with Divine graces those who love him, but it is the act of One Who is living and powerful and Who reigns for ever. Christ therefore has hereby taught us that He made no empty prophecy of the future. For He says that He made this discourse that they might have their faith in Him confirmed, when they came to think upon and reflect on His promises, after they had experienced His grace.
[AD 235] Hippolytus of Rome on John 14:30
For as a serpent cannot mark its track upon a rock, so the devil could not find sin in the body of Christ. For the Lord says, "Behold, the prince of this world cometh, and will find nothing in me." -For as a ship, sailing in the sea, leaves no traces of her way behind her, so neither does the Church, which is situate in the world as in a sea, leave her hope upon the earth, because she has her life reserved in heaven; and as she holds her way here only for a short time, it is not possible to trace out her course.-As the Church does not leave her hope behind in the world, her hope in the incarnation of Christ which bears us all good, she did not leave the track of death in Hades.-Of whom but of Him who is born of the Holy Spirit and the Virgin?-who, in renewing the perfect man in the world, works miracles, beginning from the baptism of John, as the Evangelist also testifies: And Jesus was then beginning to be about thirty years of age. This, then, was the youthful and blooming period of the age of Him who, in journeying among the cities and districts, healed the diseases and infirmities of men.

[AD 430] Augustine of Hippo on John 14:30
Why be surprised that Christ died, although Christ committed no sin whatever? He wanted to pay back for you what he did not owe himself, in order to deliver you from debt. The devil, having taken in the human race, was in possession of it by right. He possessed what he had taken; he had taken what he had taken in. Christ brought along in his mortal flesh his blood to be shed, with which to cancel the bill of our sins. That other one would still be holding the guilty if he had not put the innocent to death. But now see with what justice he is told, “You have put to death one who had no debt. Now hand over the debtors.” “Behold,” he says, “the prince of this world is coming, and in me he will find nothing.” “How nothing? Haven’t you got a soul, haven’t you got flesh? Aren’t you also the Word? Is all that nothing?”Of course not. Nothing of his own, because [I have] no sin. He is the prince of sinners. The prince of sinners will find nothing in me. I have not sinned, I have contracted nothing from Adam, because I came to you from the Virgin. I did not add anything, because I did not have anything to add it to, and by living a just life I committed no sin. Let him come and find something of his own in me, if he can. But he will find nothing of his own in me. I have no sin. Born innocently, I have led an innocent life. Let him come, he will find nothing. “So why are you dying, if he is coming and will find nothing?” And he gives the reason why he must die: “Behold, the prince of this world is coming, and he will find nothing in me.” And if we might hypothetically ask, “So then, why are you dying?” he would answer, “So that all might know that I am doing the will of my Father. Arise, let us go from here”;55 That is, let us go to [my] passion. He was willing to die because if was the will of his good Father, not because he owed it to the evil prince.

[AD 444] Cyril of Alexandria on John 14:30
Now when the impious Jews were already at hand, with the band of soldiers whom they brought, and their leader who also had promised to betray Him, and were ready to take Him and bear Him away in no long time to His sufferings upon the cross, and before the Crucifixion, He declared that He would break off His discourse with them. For, He says, the time is short and already past. And now that the bloodthirsty spirit of the Jews is at its height against Me, and shows itself already within the gates, the time for speech with you is past, and the period of My passion has arrived. But He says, The prince of this world hath nothing in Me. And I shall die very gladly, and undergo death to save the world, and through reverence to My Father and love towards Him willingly encounter inconceivable anguish, that I may fulfil His Will. The aim of what He says here is very plain, and compressing His words into smaller compass we say: Adam, the author of our race, underwent death by a Divine curse, through his breaking the commandment given to him, accused by himself and the devil. He indeed seems to have suffered for good reason, since the doom of punishment justly pursues those who have sinned from indolence; but the second Adam, that is our Lord Jesus Christ, Who can have no such charge brought against Him at all, for He did no sin, neither was guile found in His mouth, underwent His sufferings for us, having of Himself no responsibility whatever for them, but by His sufferings procured a ransom for the world, owing to His love for the Father, Who yearned for the salvation of the world. For it was truly the work of His love for the Father not to set at nought His decree and firm resolve, but to hasten to bring it into effect. And what was this decree? He willed that His own Son, though of like fashion with Himself and distinguished by His perfect equality with Him, should descend to such humiliation as to take the form of man for our sakes, and not shrink from death to save the world. This the Son did through love of His Father, Who is said to have ordered Him by His own power to suffer death in His fleshly nature, and to destroy the power of corruption, and to quicken the dead, and to restore them to their ancient state. Therefore He says that the time for speech is short. For My suffering is drawing nigh, and the presumptuous counsels of the Jews have burst into flame. I will suffer willingly, as for this cause I have come.

But the prince of this world cometh, and hath nothing in Me; that is, I shall not be convicted of sin, and the Jews will not be able to establish their charge of drunkenness against Me, the devil hath no part in Me, for vices are as it were his attributes, and wickedness owes its parentage to him. For the truth of our Saviour's words will be most clearly seen from what follows. For how did He sin, Who knew no sin, the true and living God, Who was wholly incapable of turning from the path of righteousness? And we shall see this most clearly by the actual writings of the holy Evangelists. For the most wise John has represented Pilate saying, I find no crime in Him; and again, after putting on Him the crown of thorns, as saying these words: Behold, I bring Him out to you, that ye may know that I find no crime in Him; and Matthew says that he so hated the crime, that he washed his hands before the Jews and said, I am innocent of the blood of this righteous man; and the same Evangelist points Him out to us, when He was brought into the presence of the high priests themselves, and says: Now the chief priests and the whole council sought false witness against the Christ, that they might put Him to death; and they found it not, though many false witnesses came. Still, though accusations were sought against Him by the agency of men, the devil used them as ministers and instruments of his own malice, and it was he more than any one else who sought to find sin in Him. It is then true that the devil had no part in Him, whom Christ called prince of this world, speaking of the present moment, not as though he were truly lord of it, but as a foreign intruder who has gained by the law of conquest what does not belong to him. For by sin he subjected mankind to himself, and driving them away from God as sheep who have no shepherd, he ruled over them though they were not his own. Therefore was he rightly cast out from the kingdom he had so obtained. For Christ has become King over us, and therefore He says: Now shall the prince of this world be east out; and I, if I be lifted up from the earth, will draw all men unto Myself.
[AD 397] Ambrose of Milan on John 14:31
Let us withdraw from the bond of the body and leave everything earthly so that when the adversary comes he may find nothing of his in us. Let us strive for the eternal and fly up to the divine on the wings of love and the oars of charity. Let us rise up from here, that is, from the things of the age and those of the world. For the Lord has said, “Rise, let us be on our way,” teaching that each one should arise from the earth, raise up his soul that lies on the ground, lift it to the things that are above and call forth his eagle, the eagle of whom it is said, “Your youth will be renewed like the eagle’s.”

Source: DEATH AS A GOOD 5.16
[AD 407] John Chrysostom on John 14:31
1. ' Ignorance' makes the soul timid and unmanly, just as instruction in heavenly doctrines makes it great and sublime. For when it has enjoyed no care, it is in a manner timid, not by nature but by will. For when I see the man who once was brave, now become a coward, I say that this latter feeling no longer belongs to nature, for what is natural is immutable. Again, when I see those who but now were cowards all at once become daring, I pass the same judgment, and refer all to will. Since even the disciples were very fearful, before they had learned what they ought, and had been deemed worthy of the gift of the Spirit; yet afterwards they became bolder than lions. So Peter, who could not bear the threat of a damsel, was hung with his head downwards, and was scourged, and though he endured ten thousand dangers, would not be silent, but enduring what he endured as though it were a dream, in such a situation spoke boldly; but not so before the Crucifixion. Wherefore Christ said, Arise, let us go hence. But why, tell me? Did he not know the hour at which Judas would come upon Him? Or perhaps He feared lest he should come and seize them, and lest the plotters should be upon him before he had furnished his most excellent teaching. Away with the thought! These things are far from His dignity. If then He did not fear, why did He remove them, and then after finish ing His discourse lead them into a garden known to Judas? And even had Judas come, could He not have blinded their eyes, as He also did when the traitor was not present? Why did He remove them? He allows the disciples a little breathing time. For it was likely that they, as being in a conspicuous place, would tremble and fear, both on the account of the time and the place, (for it was the depth of night,) and would not give heed to His words, but would be continually turning about, and imagining that they heard those who were to set upon them; and that more especially when their Master's speech made them expect evil. For, yet a little while, He says, and I am not with you, and, the ruler of this world comes. Since now when they heard these and the like words they were troubled, as though they should certainly be taken immediately, He leads them to another place, in order that thinking themselves in safety, they might listen to Him without fear. For they were about to hear lofty doctrines. Therefore He says, Arise, let us go hence. Then He adds, and says, I am the Vine, you are the branches. What wills He to imply by the comparison? That the man who gives no heed to His words can have no life, and that the miracles about to take place, would be wrought by the power of Christ. My Father is the Husbandman. How then? Does the Son need a power working within? Away with the thought! This example does not signify this. Observe with what exactness He goes through the comparison. He says not that the root enjoys the care of the Husbandman, but, the branches. And the foot is brought in in this place for no other purpose, but that they may learn that they can work nothing without His power, and that they ought to be united with Him by faith as the branch with the vine.
[AD 407] John Chrysostom on John 14:31
For they who now trembled and feared, after they had received the Spirit sprang into the midst of dangers and stripped themselves for the contest against steel, and fire, and wild beasts, and seas, and every kind of punishment. And they, the unlettered and ignorant, spoke so boldly as to astonish their hearers. For the Spirit made them men of iron instead of men of clay, gave them wings and allowed them to be cast down by nothing human. For such is that grace: if it finds despondency, it disperses it; if evil desires, it consumes them; if cowardice, it casts it out and does not allow one who has partaken of it to be afterward a mere person but, as it were removing him to heaven itself, causes him to imagine to himself all that is there.

Any number of different punishments will befall sinners. From all these things it will be clear that I was unjustly executed. But because of my love for the Father I accomplish his [primordial] will that all would be saved. The defeat of death that I will justly accomplish through the intervention of the omnipotent one will be the destiny for all humanity by grace.

Source: COMMENTARY ON JOHN 6.14.30-31
[AD 444] Cyril of Alexandria on John 14:31
The common and usual acceptation of the words before us suggests the thought, that as the period of the madness of the Jews had come, and the priceless Cross of our Saviour was well-nigh set up, He was hastening to depart with His holy disciples, to that place in which the band of men and officers found and took Him. And the thought is a plausible one. But probably there was another meaning hinted at; I mean a spiritual and hidden meaning. For when He says the words, Arise, let us go hence, He means to signify that to all of us there lies open by Him and with Him a change from one state to another, and a refuge from a worse condition in a better; in order that we may realise some such conception as this,----the passing from death unto life, and from corruption into incorruption, by Him and with Him, as I just said, as passing from one place into another. It is a fine saying then, Arise, and let us go hence; or you may interpret it to yourselves in some other way. From henceforth we are bound to be transformed from loving to think on earthly things into choosing the will to do God's pleasure; and besides this, to pass from slavery into the dignity of sonship; from earth into the city above; from sin to righteousness,----the righteousness I mean that is due to faith in Christ; from the impurity of man's nature to the sanctification by the Spirit; from dishonour to honour; from ignorance to knowledge; and from cowardice and faintheartedness to endurance in goodness.

Localising then, figurating as it were, our transgressions upon earth in the spot whereon He stood, He says, Arise, and let us go hence. For if this meaning entered into the scope of His speech, and He means to show thereby His affinity to us, it can do us no harm at all to act in this way, since He found it in His nature so to do. Moreover, in other places you will find Him saying to His own disciples: We must work the works of Him That sent us, while it is day; the night cometh, when no man can work. Do you hear how He implicates Himself together with us in the duty of doing work, although He does not lie under the necessity of working as we do? And this form of speech is usual with us, and we shall find it just as much amongst ourselves; and the inspired Paul, when he rebuked the Corinthians, ventured on this expression, exhorting them in these words: Now these things, my brethren, I have in a figure transferred to myself and Apollos; that in us ye might learn not to think beyond the things which are written. And there is no question that we have not an elder, nor an angel, but the Lord of all Himself, though He was not subject to our infirmities, to point out the way to all that is good, and to turn us from our old lusts to better things. For we have been ransomed not by ourselves, nor by any other creature, but rather by Christ Himself our Saviour. Therefore, when escaping as it were with us, in our company, from the wickedness of the world, He says, Arise, let us go hence. He speaks these words not as subject to it as we are, or bound by human infirmities; but as our leader and champion and guide, to point out the way to incorruption and life in sanctification and love of God.
