John 15:15

15 Henceforth I call you not servants; for the servant knoweth not what his lord doeth: but I have called you friends; for all things that I have heard of my Father I have made known unto you.
Commentaries
Irenaeuson John 15:15AD 202
Inasmuch, then, as all natural precepts are common to us and to them (the Jews), they had in them indeed the beginning and origin; but in us they have received growth and completion. For to yield assent to God, and to follow His Word, and to love Him above all, and one's neighbour as one's self (now man is neighbour to man), and to abstain from every evil deed, and all other things of a like nature which are common to both [covenants], do reveal one and the same God. But this is our Lord, the Word of God, who in the first instance certainly drew slaves to God, but afterwards He set those free who were subject to Him, as He does Himself declare to His disciples: "I will not now call you servants, for the servant knoweth not what his lord doeth; but I have called you friends, for all things which I have heard from My Father I have made known." For in that which He says, "I will not now call you servants," He indicates in the most marked manner that it was Himself who did originally appoint for men that bondage with respect to God through the law, and then afterwards conferred upon them freedom. And in that He says, "For the servant knoweth not what his lord doeth," He points out, by means of His own advent, the ignorance of a people in a servile condition. But when He terms His disciples "the friends of God," He plainly declares Himself to be the Word of God, whom Abraham also followed voluntarily and under no compulsion (sine vinculis), because of the noble nature of his faith, and so became "the friend of God." But the Word of God did not accept of the friendship of Abraham, as though He stood in need of it, for He was perfect from the beginning ("Before Abraham was," He says, "I am"), but that He in His goodness might bestow eternal life upon Abraham himself, inasmuch as the friendship of God imparts immortality to those who embrace it.
Apostolic Constitutionson John 15:15AD 380
"But blessed are your eyes, for they see; and your ears, for they hear." Yours, I say, who have believed in the one God, not by necessity, but by a sound understanding, in obedience to Him that called you. For you are released from the bonds, and freed from the servitude. For says He: "I call you no longer servants, but friends; for all things that I have heard of my Father have I made known unto you." For to them that would not see nor hear, not for the want of those senses, but for the excess of their wickedness, "I gave statutes that were not good, and judgments whereby they would not live;" they are looked upon as not good, as burnings and a sword, and medicines are esteemed enemies by the sick, and impossible to be observed on account of their obstinacy: whence also they brought death upon them being not obeyed.
Gregory of Nazianzuson John 15:15AD 390
The fear of the Lord is the beginning of wisdom, and, so to say, its first swathing band. But, when wisdom bursts the bonds of fear and rises up to love, it makes us friends of God and children instead of slaves.
Source: ON THE GREAT ATHANASIUS, ORATION 21.6
Ambrose of Milanon John 15:15AD 397
God himself made us friends instead of servants.… He gave us a pattern of friendship to follow. We are to fulfill the wish of a friend, to unfold to him our secrets that we hold in our own hearts, and are not to disregard his confidences. Let us show him our heart, and he will open his to us.… A friend, then, if he is a true one, hides nothing. He pours forth his soul as the Lord Jesus poured forth the mysteries of his Father.
John Chrysostomon John 15:14-15AD 407
"Ye are My friends-henceforth I call you not servants, for the servant knoweth not what his lord doeth. Ye are My friends, for all things which I have heard of My Father I have made known unto you."

How then saith He, "I have many things to tell you, but ye cannot bear them now"? By the "all" and the "hearing" He showeth nothing else, but that He uttered nothing alien, but only what was of the Father. And since to speak of secrets appears to be the strongest proof of friendship, "ye have," He saith, "been deemed worthy even of this communion." When however He saith "all," He meaneth, "whatever things it was fit that they should hear." Then He putteth also another sure proof of friendship, no common one.
Augustine of Hippoon John 15:15AD 430
If He made man out of filth, will He not make an angel out of man? He absolutely will. He made men His friends, will He not make them angels? I no longer call you servants, but friends. To those still bearing flesh, still dying, still dwelling in this poverty and frailty of life, He said, I no longer call you servants, but friends. And what will He give to His friends? What He showed in Himself when He rose again. They will be crowned and converted into heavenly glory and will be equal to the angels of God. There will be no corruption, no temptation. There we will not be told: Cleanse yourselves from all defilement of flesh and spirit. We will not labor, nor will we be promised a reward, because we will already have received it. Nor will we be told to groan, because we will already be praising. Thus, mortal flesh will be converted into the body of an angel. Thus, will groans be converted into praises. Here, penance, distress, and groans; there, praises, joy, and gladness.

Augustine of Hippoon John 15:15AD 430
It is a worthy subject of inquiry how these words of the Lord are to be understood, "But I have called you friends: for all things that I have heard of my Father I have made known unto you." For who is there that dare affirm or believe that any man knoweth all things that the only-begotten Son hath heard of the Father; when there is no one that can comprehend even how He heareth any word of the Father, being as He is Himself the only Word of the Father? Nay more, is it not the case that a little afterwards, in this same discourse, which He delivered to the disciples between the Supper and His passion, He said, "I have yet many things to say unto you, but ye cannot bear them now"? How, then, are we to understand that He made known unto the disciples all that He had heard of the Father, when there are many things that He saith not, just because He knows that they cannot bear them now? Doubtless what He is yet to do He says that He has done as the same Being who hath made those things which are yet to be. For as He says by the prophet, "They pierced my hands and my feet," and not, They will yet pierce; but speaking as it were of the past, and yet predicting what was still in the future: so also in the passage before us He declares that He has made known to the disciples all, that He knows He will yet make known in that fullness of knowledge, whereof the apostle says, "But when that which is perfect is come, then that which is in part shall be done away." For in the same place he adds: "Now I know in part, but then shall I know, even as also I am known; and now through a glass in a riddle, but then face to face." For the same apostle also says that we have been saved by the washing of regeneration, and yet declares in another place, "We are saved by hope: but hope that is seen is no hope; for what a man seeth, why doth he yet hope for? But if we hope for that we see not, then do we with patience wait for it." To a similar purpose it is also said by his fellow-apostle Peter, "In whom, though now seeing Him not, ye believe; and in whom, when ye see Him, ye shall rejoice with a joy unspeakable and glorious: receiving the reward of faith, even the salvation of your souls." If, then, it is now the season of faith, and faith's reward is the salvation of our souls; who, in that faith which worketh by love, can doubt that the day must come to an end, and at its close the reward be received; not only the redemption of our body, whereof the Apostle Paul speaketh, but also the salvation of our souls, as we are told by the Apostle Peter? For the felicity springing from both is at this present time, and in the existing state of mortality, a matter rather of hope than of actual possession. But this it concerns us to remember, that our outward man, to wit the body, is still decaying; but the inward, that is, the soul, is being renewed day by day. Accordingly, while we are waiting for the immortality of the flesh and salvation of our souls in the future, yet with the pledge we have received, it may be said that we are saved already; so that knowledge of all things which the Only-begotten hath heard of the Father we are to regard as a matter of hope still lying in the future, although declared by Christ as something He had already imparted.
Augustine of Hippoon John 15:15AD 430
But let us mark what follows. "Henceforth I call you not servants; for the servant knoweth not what his lord doeth." How, then are we to understand the good servant to be both servant and friend, when He says, "Henceforth I call you not servants; for the servant knoweth not what his lord doeth"? He introduces the name of friend in such a way as to withdraw that of servant; not as if to include both in the one term, but in order that the one should succeed to the place vacated by the other. What does it mean? Is it this, that even in doing the Lord's commandments we shall not be servants? Or this, that then we shall cease to be servants, when we have been good servants? And yet who can contradict the Truth, when He says, "Henceforth I call you not servants?" and shows why He said so: "For the servant," He adds, "knoweth not what his lord doeth." Is it that a good and tried servant is not likewise entrusted by his master with his secrets? What does He mean, then, by saying, "The servant knoweth not what his lord doeth"? Be it that "he knoweth not what he doeth," is he ignorant also of what he commands? For if he were so, how can he serve? Or how is he a servant who does no service? And yet the Lord speaks thus: "Ye are my friends, if ye do whatsoever I command you. Henceforth I call you not servants." Truly a marvellous statement! Seeing we cannot serve the Lord but by doing His commandments, how is it that in doing so we shall cease to be servants? If I be not a servant in doing His commandments, and yet cannot be in His service unless I so do, then, in my very service, I am no longer a servant.
Augustine of Hippoon John 15:15AD 430
Let us understand, and may the Lord enable us to understand, and enable us also to do what we understand. And if we know this, we know of a truth what the Lord doeth; for it is only the Lord that so enables us, and by such means only do we attain to His friendship. For just as there are two kinds of fear, which produce two classes of fearers; so there are two kinds of service, which produce two classes of servants. There is a fear, which perfect love casteth out; and there is another fear, which is clean, and endureth for ever. The fear that lies not in love, the apostle pointed to when he said, "For ye have not received the spirit of service again to fear." But he referred to the clean fear when he said, "Be not high-minded, but fear." In that fear which love casteth out, there has also to be cast out the service along with it: for both were joined together by the apostle, that is, the service and the fear, when he said, "For ye have not received the spirit of service again to fear." And it was the servant connected with this kind of service that the Lord also had in His eye when He said, "Henceforth I call you not servants; for the servant knoweth not what his lord doeth." Certainly not the servant characterized by the clean fear, to whom it is said, "Well done, thou good servant: enter thou into the joy of thy lord;" but the servant who is characterized by the fear which love casteth out, of whom He elsewhere saith, "The servant abideth not in the house for ever, but the Son abideth ever." Since, therefore, He hath given us power to become the sons of God, let us not be servants, but sons: that, in some wonderful and indescribable but real way, we may as servants have the power not to be servants; servants, indeed, with that clean fear which distinguishes the servant that enters into the joy of his lord, but not servants with the fear that has to be cast out, and which marketh him that abideth not in the house for ever.
Augustine of Hippoon John 15:15AD 430
But let us bear in mind that it is the Lord that enableth us to serve so as not to be servants. And this it is that is unknown to the servant, who knoweth not what his Lord doeth; and who, when he doeth any good thing, is lifted up as if he did it himself, and not his Lord; and so, glories not in the Lord, but in himself, thereby deceiving himself, because glorying, as if he had not received. But let us, beloved, in order that we may be the friends of the Lord, know what our Lord doeth. For it is He who makes us not only men, but also righteous, and not we ourselves. And who but He is the doer, in leading us to such a knowledge? For "we have received not the spirit of this world, but the Spirit which is of God, that we might know the things that are freely given to us of God." Whatever good there is, is freely given by Him. And so because this also is good, by Him who graciously imparteth all good is this gift of knowing likewise bestowed; that, in respect of all good things whatever, he that glorieth may glory in the Lord.
Augustine of Hippoon John 15:14-15AD 430
(viii. de Trin. c. viii) From one and the same love, we love God and our neighbour; but God for His own sake, our neighbour for God's. So that, there being two precepts of love, on which hang all the Law and the Prophets, to love God, and to love our neighbour, Scripture often unites them into one precept. For if a man love God, it follows that he does what God commands, and if so, that he loves his neighbour, God having commanded this. Wherefore He proceeds: Ye are My friends, if ye do whatsoever I command you.

(Tract. lxxxv. 2) Great condescension! Though to keep his Lord's commandments, is only what a good servant is obliged to do, yet, if they do so, He calls them His friends. The good servant is both the servant, and the friend. But how is this? He tells us: Henceforth I call you not servants, for the servant knoweth not what his Lord doeth. Shall we therefore cease to be servants, as soon as ever we are good servants? And is not a good and tried servant sometimes entrusted with his master's secrets, still remaining a servant? (c. 3.). We must understand then that there are two kinds of servitude, as there are two kinds of fear. There is a fear which perfect love casteth out; which also hath in it a servitude, which will be cast out together with the fear. And there is another, a pure (castus) fear, which remaineth for ever. It is the former state of servitude, which our Lord refers to, when He says, Henceforth I call you not servants, for the servant knoweth not what his Lord doeth; not the state of that servant to whom it is said, Well done, thou good servant, enter thou into the joy of thy Lord: (Matt. 25:21) but of him of whom it was said below, The servant abideth not in the house for ever, but the Son abideth ever. Forasmuch then as God hath given us power to become the sons of God, so that in a wonderful way, we are servants, and yet not servants, we know that it is the Lord who doth this. This that servant is ignorant of, who knoweth not what his Lord doeth, and when he doeth any good thing, is exalted in his own conceit, as if he himself did it, and not his Lord; and boasts of himself, not of his Lord.
But I have called you friends, for all things that I have heard of My Father, I have made known unto you.

(Tract. lxxxvi. 1) But how did He make known to His disciples all things that He had heard from the Father, when He forebore saying many things, because He knew they as yet could not bear them? He made all things known to His disciples, i. e. He knew that He should make them known to them in that fulness of which the Apostle saith, Then we shall know, even as we are known. (1 Cor. 13:12) For as we look for the death of the flesh, and the salvation of the soul; so should we look for that knowledge of all things, which the Only-Begotten heard from the Father.
Cyril of Alexandriaon John 15:15AD 444
But we must consider this point especially at this juncture, for it will be of no small profit. For if friendship towards Christ will be sufficient in the case of any for the dignity of freedom and the being no longer called slaves, how could He be a slave except as made and created, according to the thoughtlessness of some? For He is not able to allot the honour of freedom to all others, while His own Nature is bereft of this attribute. For I suppose He must appear in possession of it more than all the rest, for then will He most suitably give to those who have it not the blessing that is His own. But the dignity must be conferred on and given to the holy Apostles, or perhaps also to all others who mount up through faith to the friendship that is towards our Lord Jesus Christ, as by way of honour, but not existing in like manner with that enjoyed by Him. For they, mounting up by their likeness to Him to the glory of liberty, would display by this that which naturally belongs to Him alone. For that which is by position is compared with that which is by nature.

This however we must demonstrate; for I think it is necessary to go through every inquiry which is useful and particularly necessitates explanation. For the justice which is derived from faith in Christ has a more ancient manifestation than that justice which is according to the law; and further, because the knowledge of the Divine mysteries is revealed to those that believe and obey Christ, and the counsel of God the Father is interpreted by him who knows that of the Son, but to those who are disobedient, not at all.

Come then, let us again illustrate this by the inspired Scripture, dwelling somewhat at length upon it to advantage. It has then been written in a book of Moses that Abraham believed in God, but his faith was accounted unto him for righteousness; and he was called the friend of God. And what was the manner of his faith, or how then was he called the friend of God? He heard the words, Get thee out of thy country, and from thy kindred, unto a land that I will show thee. Moreoyer, when he was enjoined to sacrifice his only son as a type of Christ he learnt the purpose hidden in God. And for this reason the Saviour spoke concerning him to the impious Jews, saying: Your father Abraham rejoiced to see My day; and he saw it and was glad. Therefore the inspired Abraham, owing to obedience and sacrifice, was called the friend of God and put on himself the boast of righteousness.

And not only this, but he was deemed worthy of Divine converse, and knew the counsel of God, which came to pass in the last times. For in the fulness of time Christ died for us----the true, sacred, and holy sacrifice which taketh away the sin of the world.

But see again a like fulfilment in the case of those who mount up by faith to the friendship of our Saviour Christ. They also heard the words Get thee out of thy country. And that they did it eagerly we may learn from what they say: For we have not here an abiding city, but we seek after the city which is to come, whose builder and maker is God. For they are strangers and sojourners upon earth, being citizens of heaven and leaving the land of their birth to speak allegorically of their heavenward aspirations, desiring eagerly the resting-place above. For this the Saviour set before them when He said, I go and will prepare a place for you; and when I come, I will receive you with Myself; that where I am, there ye may be also. They were told to go forth from their kindred; and how shall we show this? We will refer to Christ's own words: He that loveth father or mother more than Me is not worthy of Me. And that the things of God were preferred to their earthly and fleshly relationship, and their love towards Christ set forth as far stronger, is certainly unquestioned among those who reverence Him. And the blessed Abraham was ordered to bring to God his own son for an odour of a sweet-smelling savour, while others, girding themselves with the righteousness that is by faith, were commanded to offer not others but themselves. For he says: Present your bodies a living sacrifice, holy, acceptable to God, which is your reasonable service. Since it has been written concerning them: They that are of Christ Jesus have crucified the flesh with the passions and the lusts thereof, they knew the mystery that is in Christ. For they know the powers of the age to come, and what will be in the last days; for they will receive the rewards of their labours, and take as requital the recompence of their piety towards Christ. Therefore we shall become just and the friends of God, as did Abraham. And the Gospel dispensation is far more ancient than that of the Law. I mean by the Gospel dispensation that which is by faith and friendship towards God, then moulded first in Abraham, as in the beginning of his race according to the flesh, that is of Israel, but now coming as from a type to truth, and being well fulfilled in the holy disciples themselves, as in the beginning of a spiritual race preserved as a people for God's own possession, which also is called a holy nation and a royal priesthood. Therefore it has been said to the mother of the Jews, I mean the synagogue, by the voice of the Psalmist: Instead of fathers thy sons have been born.

For the inspired disciples are truly sons of the synagogue of the Jews, for they were nourished up in the Mosaic usages. They became fathers, holding the position of Abraham, and were the beginning of the spiritual race, and for this reason were ordained as rulers, offering up as a sacrifice the Gospel of Christ in all the world, as did Abraham Isaac as a type of Christ. We thus speak, not depriving the blessed Abraham of the glory which is his due and befits him, but showing in him, as in a figure, what has been appointed in the last days by Christ. The reward of friendship with God which was then seen in Abraham first is intimately conjoined with the freedom which comes by faith, and now also it is seen in the holy disciples as the firstfruits of a new generation. Let then the inspired Paul point out to us the necessity of thus speaking, vehemently contending with the Jews, that the righteousness that is of faith is far older than that of the Law. For when he made mention of the circumcision according to the flesh, he affirmed that this was given to the firstfruits of the race, that is Abraham, for no other reason save his becoming the sign and seal of the faith which he had while he was in uncircumcision. But if uncircumcision with which also is faith was before the Law, but circumcision which has not the glory of faith after the Law, and Abraham believed in uncircumcision, how will not the justice through faith of those who are justified and freed through love towards God, as was Abraham, be more ancient than the dispensation by the Law? For thus also he will be father of many nations by promise, not according to the flesh. And these things have we now pertinently said on account of our Lord's word: No longer do I call you servants: ye are My friends; for all things that I heard from My Father, I have made known unto you.
Gregory the Dialogiston John 15:15AD 604
(Hom. xxvii.) Or all things which He heard from the Father, which He wished to be made known to His servants; the joys of spiritual love, the pleasures of our heavenly country, which He impresses daily on our minds by the inspiration of His love. For while we love the heavenly things we hear, we know them by loving, because love is itself knowledge. He had made all things known to them then, because being withdrawn from earthly desires, they burned with the fire of divine love.
Gregory the Dialogiston John 15:15AD 604
"I will no longer call you servants, because the servant does not know what his master does. But I have called you friends, because all things whatsoever I have heard from my Father, I have made known to you." What are all these things which He heard from His Father, which He wished to make known to His servants, that He might make them His friends, except the joys of interior charity, except those festivals of the heavenly homeland, which He daily imprints on our minds through the inspiration of His love? For when we love the heavenly things we have heard, we already know what we love, because love itself is knowledge. Therefore He had made all things known to those who, changed from earthly desires, were burning with the torches of supreme love. Indeed the Prophet had beheld these friends of God when he said: "But to me Your friends, O God, are exceedingly honored." For a friend is called, as it were, a guardian of the soul. Because therefore the Psalmist foresaw that the elect of God, separated from the love of this world, would guard the will of God in heavenly commandments, he marveled at the friends of God, saying: "But to me Your friends, O God, are exceedingly honored." And as if we were immediately asking him to reveal to us the reasons for such great honor, he at once added: "Their sovereignty is exceedingly strengthened." Behold, the elect of God subdue the flesh, strengthen the spirit, command demons, shine with virtues, despise present things, preach the eternal homeland by their conduct as well as by their voice; they love it even unto death, and reach it through torments. They can be killed, but they cannot be bent. Therefore their sovereignty is exceedingly strengthened. In that very passion by which they fell in the death of the flesh, see how great was the height of their minds. Whence this, except because their sovereignty was strengthened? But perhaps those who are so great are few? He added: "I will count them, and they will be multiplied beyond the sand." Behold the whole world, brothers: it is full of martyrs. Now we are scarcely as many as we can see compared to how many witnesses of the truth we have. Therefore those who are countable to God are multiplied beyond the sand for us, because how many they are cannot be comprehended by us.
Theophylact of Ohridon John 15:15AD 1107
"I," He says, "love you so much that I have revealed to you ineffable mysteries. For I have communicated to you all that I heard from My Father."
How then does He say in another place (John 16:12): "I have many things to say to you, but you cannot bear them now"? He communicated to them everything that they were able to hear and that they could now understand. And when He says "all things that I have heard from My Father," do not think that He needs to be taught, but rather He shows that He proclaims nothing foreign, but only what belongs to the Father, and that all His words are the words of the Father.
Bernard of Clairvauxon John 15:15AD 1153
Nor is John the only one, it is true also of all to whom the Angel of the Great Counsel said: "I call you friends, because I have made known to you everything I have learnt from my Father." Paul drank of it, because the Good News he preached is not a human message nor did he receive it through men, it is something he learned only through a revelation of Jesus Christ.

All of these indeed could say with felicity and truth: "It is the only Son who is in the Father's bosom who has made it known to us." And this revelation -- what can you call it but a kiss? But it was the kiss of the kiss, not of the mouth.
Bonaventureon John 15:15AD 1257
No longer will I call you servants, although previously you were: Romans 8: "You have not received the spirit of servitude again in fear, but the spirit of the adoption of sons." And he shows this by a sign: Because the servant does not know what his lord does: but you are not so: therefore he says: But I have called you friends, because all things whatsoever I have heard from my Father, I have made known to you. This is a sign of great friendship, the revelation of secrets: Ephesians 1: "He has made known to us the mystery of his will"; Matthew 13: "To you it has been given to know the mysteries of the kingdom of God," etc.

Question IV. Likewise it is asked about what he says: I will no longer call you servants.

Contra: 1. Matthew 25: Well done, good and faithful servant; and if he calls those about to be beatified servants, what then does he mean when he says: I will not call you servants?

2. Likewise, above in chapter 13 he called himself their lord; therefore by the correlation of relatives he also called them servants.

I respond: It must be said that servant is said in two ways: in one way, insofar as it denotes obedience and subjection; and in this sense servant is not distinguished from friend, and thus all friends of God are his servants. In another way, servant is said of one who fears in a servile manner; and such a one, who serves from fear alone, is not a friend. And he speaks here of such a one, because he did not want them to fulfill his commandments in a servile manner, but rather in a manner befitting friends.

Question V. Likewise it is asked about what he says: All things whatsoever I have heard from my Father, I have made known to you.

On the contrary: The Son heard infinite things from the Father; therefore he made known infinite things.

They respond that he does not speak of those things which he heard insofar as he is God, but insofar as he is man.

Then it is objected: because Christ as man knew the day of judgment, yet he did not wish to reveal it to his disciples.

On account of this they respond further that [he made known] all things pertaining to salvation.

On the contrary: below in chapter 16: I have yet many things to say to you, which you cannot bear now; and it is certain that [these pertained] to their salvation; therefore etc.

Augustine responds: He made all things known, that is, he disposed to make them known; for Scripture frequently speaks in this way, putting the past tense in place of the future as a sign of certainty.

Or: all things necessary for salvation according as they were able to grasp them. And thus all things are clear.
Thomas Aquinason John 15:15AD 1274
2013 The sign of Christ's friendship for them is mentioned when he says, No longer do I call you servants. First, he excludes what seems opposed to friendship; secondly, he mentions the sign of true friendship (v 15b).

2014 Servitude is opposed to friendship; and he rejects this by saying, No longer do I call you servants. It is like saying: although you were formerly servants under the law, now you are free under grace: "You have received the spirit of adoption" [Rom 8:15].

Secondly, he adds the reason for this when he says, for the servant does not know what his master is doing: for a servant is like a stranger to his master, "The slave does not continue in the house for ever" (8:35). Now secrets should not be told to strangers, "Do not tell a secret to a stranger" [Prv 25:9]. And so secrets should not be given to those who are now servants. This verse shows the servant does not act for the sake of himself, because charity does not seek its own, but the interests of Jesus and the salvation of one's neighbor. Those who act entirely by reason of another are bad servants. Thus it is clear that the disciples were servants, but it was a good servitude springing from love.

As for the second difficulty, we should say that the servant who is moved only by another and not by himself, is related to the one who moves him as a tool to the worker. Now a tool shares with the worker in the work, but not in the reason for the work. So such servants share only in the work. But when a servant acts by his own will, it is necessary for him to know the reason for the work and have secrets revealed to him so he can know what he is doing. "If you have a servant, regard him as your own soul" [Sir 33:31]. Now the apostles, as was said, were moved by themselves to accomplish good works, that is, they were moved by their own will, inclined by love. And so our Lord revealed his secrets to them. But bad servants do not know what their master is doing. What things don't they know? Strictly speaking, they do not know what God does in us. For God acts in us in all the good we do: "O Lord... you have wrought for us all our works" (Is 26:12). So the bad servant, darkened by the pride in his own heart, does not know what his master is doing when this servant attributes to himself what he does.

2016 Now he sets down the true sign of friendship on his own part, which is that all that I have heard from my Father I have made known to you. For the true sign of friendship is that a friend reveals the secrets of his heart to his friend. Since friends have one mind and heart, it does not seem that what one friend reveals to another is placed outside his own heart: "Argue your case with your neighbor" (Prv 25:9). Now God reveals his secrets to us by letting us share in his wisdom: "In every generation she [Wisdom] passes into holy souls and makes them friends of God and prophets" (Wis 7:27).

2017 There is a question here as to what and in what way the Son hears from the Father. The answer has already been indicated in many ways. Since to hear is to receive knowledge from another, for the Son to hear from the Father is nothing other than for the Son to receive knowledge from the Father. Now the knowledge of the Son is his own essence. Thus, for the Son to hear from the Father is for the Son to receive his essence from the Father.

2018 Another question concerns the statement, all that I have heard from my Father I have made known to you. If he did make all things known to them it would follow that the disciples knew as much as the Son. The answer, according to Chrysostom, is that all that I have heard means all that I have heard which you ought to hear, but not absolutely all things, I have made known to you: "I have yet many things to say to you, but you cannot bear them now" (16:12).

Or, one could say, according to Augustine, that what he would say to them was so certain that he used the past tense instead of the future. So the meaning becomes, all that I have heard from my Father I have made known to you, that is, I will make known with that fullness of which the Apostle says: "Then I shall understand fully, even as I have been fully understood" (1 Cor 13:12). And below we read, "The hour is coming when I shall tell you plainly of the Father" (16:25), that is, when I lead you to the vision of the Father. For all things the Son knows the Father knows. So when he reveals the Father to us, the Son will reveal all that the Son himself knows and which we know.

Again, one could say with Gregory, and this is better, that the same thing can be known perfectly or imperfectly. For example, in the sciences it is obvious that a person who knows all the principles of a science is said to know that science, although imperfectly. And so a person who teaches some principles of a science can say that he teaches that science, because everything that belongs to that science is virtually contained in its principles. But one will know that same science more perfectly when he knows the individual conclusions which are virtually in the principles. In the same way we can have a twofold knowledge of divine matters. One is imperfect, and is gained by faith, which is a foretaste of that future happiness and knowledge which we will have in heaven: "Faith is the substance of things to be hoped for" [Heb 11:2]. He says of this knowledge, all... I have made known to you, that is, in faith, by a kind of foretaste, like conclusions are virtually contained in their principles. So Gregory says: "All the things he has made known to his servants are the joys of interior love and the feasts of our heavenly fatherland, which he excites in our minds every day by the breath of his love. For as long as we love the sublime heavenly things we have heard, we already know what we love, because the love itself is knowledge."
CS Lewison John 15:15AD 1963
How or why does such faith occur sometimes, but not always, even in the perfect petitioner? We, or I, can only guess. My own idea is that it occurs only when the one who prays does so as God's fellow-worker, demanding what is needed for the joint work. It is the prophet's, the apostle's, the missionary's, the healer's prayer that is made with this confidence and finds the confidence justified by the event. The difference, we are told, between a servant and a friend is that a servant is not in his master's secrets. For him, "orders is orders". He has only his own surmises as to the plans he helps to execute. But the fellow-worker, the companion or (dare we say?) the colleague of God is so united with Him at certain moments that something of the divine foreknowledge enters his mind. Hence his faith is the "evidence"—that is, the evidentness, the obviousness—of things not seen.

As the friend is above the servant, the servant is above the suitor, the man praying on his own behalf.
