1 Judge not, that ye be not judged. 2 For with what judgment ye judge, ye shall be judged: and with what measure ye mete, it shall be measured to you again. 3 And why beholdest thou the mote that is in thy brother's eye, but considerest not the beam that is in thine own eye? 4 Or how wilt thou say to thy brother, Let me pull out the mote out of thine eye; and, behold, a beam is in thine own eye? 5 Thou hypocrite, first cast out the beam out of thine own eye; and then shalt thou see clearly to cast out the mote out of thy brother's eye. 6 Give not that which is holy unto the dogs, neither cast ye your pearls before swine, lest they trample them under their feet, and turn again and rend you. 7 Ask, and it shall be given you; seek, and ye shall find; knock, and it shall be opened unto you: 8 For every one that asketh receiveth; and he that seeketh findeth; and to him that knocketh it shall be opened. 9 Or what man is there of you, whom if his son ask bread, will he give him a stone? 10 Or if he ask a fish, will he give him a serpent? 11 If ye then, being evil, know how to give good gifts unto your children, how much more shall your Father which is in heaven give good things to them that ask him? 12 Therefore all things whatsoever ye would that men should do to you, do ye even so to them: for this is the law and the prophets. 13 Enter ye in at the strait gate: for wide is the gate, and broad is the way, that leadeth to destruction, and many there be which go in thereat: 14 Because strait is the gate, and narrow is the way, which leadeth unto life, and few there be that find it. 15 Beware of false prophets, which come to you in sheep's clothing, but inwardly they are ravening wolves. 16 Ye shall know them by their fruits. Do men gather grapes of thorns, or figs of thistles? 17 Even so every good tree bringeth forth good fruit; but a corrupt tree bringeth forth evil fruit. 18 A good tree cannot bring forth evil fruit, neither can a corrupt tree bring forth good fruit. 19 Every tree that bringeth not forth good fruit is hewn down, and cast into the fire. 20 Wherefore by their fruits ye shall know them. 21 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. 22 Many will say to me in that day, Lord, Lord, have we not prophesied in thy name? and in thy name have cast out devils? and in thy name done many wonderful works? 23 And then will I profess unto them, I never knew you: depart from me, ye that work iniquity. 24 Therefore whosoever heareth these sayings of mine, and doeth them, I will liken him unto a wise man, which built his house upon a rock: 25 And the rain descended, and the floods came, and the winds blew, and beat upon that house; and it fell not: for it was founded upon a rock. 26 And every one that heareth these sayings of mine, and doeth them not, shall be likened unto a foolish man, which built his house upon the sand: 27 And the rain descended, and the floods came, and the winds blew, and beat upon that house; and it fell: and great was the fall of it. 28 And it came to pass, when Jesus had ended these sayings, the people were astonished at his doctrine: 29 For he taught them as one having authority, and not as the scribes.

Let us therefore, brethren, be of humble mind, laying aside all haughtiness, and pride, and foolishness, and angry feelings; and let us act according to that which is written (for the Holy Spirit says, "Let not the wise man glory in his wisdom, neither let the mighty man glory in his might, neither let the rich man glory in his riches; but let him that glories glory in the Lord, in diligently seeking Him, and doing judgment and righteousness" [Jeremiah 9:23-24]), being especially mindful of the words of the Lord Jesus which He spoke teaching us meekness and long-suffering. For thus He spoke: "Be merciful, that you may obtain mercy; forgive, that it may be forgiven to you; as you do, so shall it be done unto you; as you judge, so shall you be judged; as you are kind, so shall kindness be shown to you; with what measure you measure, with the same it shall be measured to you." [Matthew 5:7, Matthew 6:14, Matthew 7:1-2] By this precept and by these rules let us establish ourselves, that we walk with all humility in obedience to His holy words. For the holy word says, "On whom shall I look, but on him that is meek and peaceable, and that trembles at my words?" [Isaiah 66:2]

And therefore has the Lord said: "Judge not, that you be not judged: for with what judgment you shall judge, you shall be judged." [Matthew 7:1-2] [The meaning is] not certainly that we should not find fault with sinners, nor that we should consent to those who act wickedly; but that we should not pronounce an unfair judgment on the dispensations of God, inasmuch as He has Himself made provision that all things shall turn out for good, in a way consistent with justice. For, because He knew that we would make a good use of our substance which we should possess by receiving it from another, He says, "He that has two coats, let him impart to him that has none; and he that has meat, let him do likewise." [Luke 3:11] And, "For I was an hungered, and you gave Me meat; I was thirsty, and you gave Me drink; I was naked and you clothed Me." [Matthew 25:35-36] And, "When you do your alms, let not your left hand know what your right hand does." [Matthew 6:3] And we are proved to be righteous by whatsoever else we do well, redeeming, as it were, our property from strange hands.

[AD 220] Tertullian on Matthew 7:1
Is there any risk of a different result in the case of a Lord so just in estimating, so potent in executing? Why, then, do we believe Him a Judge, if not an Avenger too? This He promises that He will be to us in return, saying, "Vengeance belongeth to me, and I will avenge; " that is, Leave patience to me, and I will reward patience. For when He says, "Judge not, lest ye be judged," does He not require patience? For who will refrain from judging another, but he who shall be patient in not revenging himself? Who judges in order to pardon? And if he shall pardon, still he has taken care to indulge the impatience of a judger, and has taken away the honour of the one Judge, that is, God.

"But," say they, "God is `good, 'and `most good, ' and `pitiful-hearted, 'and `a pitier, 'and `abundant in pitiful-heartedness, ' which He holds `dearer than all sacrifice, ' `not thinking the sinner's death of so much worth as his repentance', `a Saviour of all men, most of all of believers.' And so it will be becoming for `the sons of God' too to be `pitiful-hearted' and `peacemakers; ' `giving in their turn just as Christ withal hath given to us; ' `not judging, that we be not judged.' For `to his own lord a man standeth or falleth; who art thou, to judge another's servant? ' `Remit, and remission shall be made to thee.'"

Otherwise; He forbids us to judge God touching His promises; for as judgments among men are founded on things uncertain, so this judgment against God is drawn from somewhat that is doubtful. And He therefore would have us put away the custom from us altogether; for it is not here as in other cases where it is sin to have given a false judgment; but here we have begun to sin if we have pronounced any judgment at all.

Wherefore He does not say, 'Do not cause a sinner to cease,' but do not judge; that is, be not a bitter judge; correct him indeed, but not as an enemy seeking revenge, but as a physician applying a remedy.

Otherwise; He does not forbid us to judge all sin absolutely, but lays this prohibition on such as are themselves full of great evils, and judge others for very small evils. In like manner Paul does not absolutely forbid to judge those that sin, but finds fault with disciples that judged their teacher, and instructs us not to judge those that are above us.

[AD 407] John Chrysostom on Matthew 7:1
What then? Ought we not to blame them that sin? Because Paul also says this selfsame thing: or rather, there too it is Christ, speaking by Paul, and saying, Romans 14:10 Why do you judge your brother? And thou, why do you set at nought your brother? and, Who are you that judgest another man's servant? Romans 14:4 And again, Therefore judge nothing before the time, until the Lord come. 1 Corinthians 4:5

How then does He say elsewhere, Reprove, rebuke, exhort, 2 Timothy 4:2 and, Them that sin rebuke before all? And Christ too to Peter, Go and tell him his fault between you and him alone, and if he neglect to hear, add to yourself another also; and if not even so does he yield, declare it to the church likewise? And how has He set over us so many to reprove; and not only to reprove, but also to punish? For him that hearkens to none of these, He has commanded to be as a heathen man and a publican. Matthew 18:17 And how gave He them the keys also? Since if they are not to judge, they will be without authority in any matter, and in vain have they received the power to bind and to loose.

And besides, if this were to obtain, all would be lost alike, whether in churches, or in states, or in houses. For except the master judge the servant, and the mistress the maid, and the father the son, and friends one another, there will be an increase of all wickedness. And why say I, friends? Unless we judge our enemies, we shall never be able to put an end to our enmity, but all things will be turned upside down.

What then can the saying be? Let us carefully attend, lest the medicines of salvation, and the laws of peace, be accounted by any man laws of overthrow and confusion. First of all, then, even by what follows, He has pointed out to them that have understanding the excellency of this law, saying, Why do you behold the mote that is in your brother's eye, but considerest not the beam that is in your own eye? Matthew 7:3

But if to many of the less attentive, it seem yet rather obscure, I will endeavor to explain it from the beginning. In this place, then, as it seems at least to me, He does not simply command us not to judge any of men's sins, neither does He simply forbid the doing of such a thing, but to them that are full of innumerable ills, and are trampling upon other men for trifles. And I think that certain Jews too are here hinted at, for that while they were bitter accusing their neighbors for small faults, and such as came to nothing, they were themselves insensibly committing deadly sins. Herewith towards the end also He was upbraiding them, when He said, You bind heavy burdens, and grievous to be borne, but you will not move them with your finger, Matthew 23:4 and, ye pay tithe of mint and anise, and have omitted the weightier matters of the law, judgment, mercy, and faith. Matthew 23:23

Well then, I think that these are comprehended in His invective; that He is checking them beforehand as to those things, wherein they were hereafter to accuse His disciples. For although His disciples had been guilty of no such sin, yet in them were supposed to be offenses; as, for instance, not keeping the sabbath, eating with unwashen hands, sitting at meat with publicans; of which He says also in another place, You which strain at the gnat, and swallow the camel. But yet it is also a general law that He is laying down on these matters.

And the Corinthians 1 Corinthians 4:5 too Paul did not absolutely command not to judge, but not to judge their own superiors, and upon grounds that are not acknowledged; not absolutely to refrain from correcting them that sin. Neither indeed was He then rebuking all without distinction, but disciples doing so to their teachers were the object of His reproof; and they who, being guilty of innumerable sins, bring an evil report upon the guiltless.

This then is the sort of thing which Christ also in this place intimated; not intimated merely, but guarded it too with a great ter ror, and the punishment from which no prayers can deliver.

(Chapter VII - Verses 1, 2) Do not judge, so that you may not be judged. For with the judgment you judge, you will be judged; and with the measure you use, it will be measured to you. If judging is prohibited, what is the consequence of Paul judging the fornicator in Corinth (1 Cor. 5), and Peter rebuking Ananias and Sapphira for lying (Acts 5)? But he shows what he prohibits from the consequences, saying: just as you judge, you will be judged. Therefore, he did not prohibit judgment, but taught it.

[AD 430] Augustine of Hippo on Matthew 7:1-2
(ubi sup.) Since when these temporal things are provided beforehand against the future, it is uncertain with what purpose it is done, as it may be with a single or double mind, He opportunely subjoins, Judge not.

(Serm. in Mont. ii. 18.) I suppose the command here to be no other than that we should always put the best interpretation on such actions as seem doubtful with what mind they were done. But concerning such as cannot be done with good purpose, as adulteries, blasphemies, and the like, He permits us to judge; but of indifferent actions which admit of being done with either good or bad purpose, it is rash to judge, but especially so to condemn. There are two cases in which we should be particularly on our guard against hasty judgments, when it does not appear with what mind the action was done; and when it does not yet appear, what sort of man any one may turn out, who now seems either good or bad. Wherefore we should neither blame those things of which we know with what mind they are done, nor so blame those things which are manifest, as though we despaired of recovery. Here one may think there is difficulty in what follows, With what judgment ye judge ye shall be judged. If we judge a hasty judgment, will God also judge us with the like? Or if we have measured with a false measure, is there with God a false measure whence it may be measured to us again? For by measure I suppose is here meant judgment. Surely this is only said, that the haste in which you punish another shall be itself your punishment. For injustice often does no harm to him who suffers the wrong; but must always hurt him who does the wrong.

(De. Civ. Dei, xxi. 11.) Some say, How is it true that Christ says, And with what measure ye shall mete it shall be measured to you again, if temporal sin is to be punished by eternal suffering? They do not observe that it is not said the same measure, because of the equal space of time, but because of the equal retribution—namely, that he who has done evil should suffer evil, though even in that sense it might be said of that of which the Lord spoke here, namely of judgments and condemnations. Accordingly, he that judges and condemns unjustly, if he is judged and condemned, justly receives in the same measure though not the same thing that he gave; by judgment he did what was unjust, by judgment he suffers what is just.

[AD 430] Augustine of Hippo on Matthew 7:1-2
This carries the same intent as another passage, “Pass no judgment before the time, until the Lord comes, who will both bring to light the hidden things of darkness and reveal the thoughts of the heart; and then everyone will have his praise from God.” Some actions are indifferent, and, since we do not know with what intention they are performed, it would be rash for any to pass judgment on them and most rash to condemn them. The time for judging these actions will come later, when the Lord “will bring to light the hidden things of darkness and reveal the thoughts of the heart.” And in another passage the same apostle also says, “Some sins are manifest even before the judgment, but some sins afterward.” When it is clear with what intention they are committed, he calls them manifest sins, and these sins precede judgment. This means that if judgment follows them at once, it will not be rash judgment. But concealed sins follow judgment, because not even these will remain hidden in their proper time. And this is to be understood about good works as well, for he thus continues: “In like manner also the good works are manifest, and whatever things are otherwise cannot be hidden.” On things that are manifest, therefore, let us pass judgment, but with regard to hidden things, let us leave the judgment to God. For whether the works themselves be bad or good, they cannot remain hidden when the time comes for them to be revealed.

[AD 430] Augustine of Hippo on Matthew 7:1
And inasmuch as when such things are either provided against the time to come, or reserved, if there is no cause wherefore you should expend them, it is uncertain with what intention it is done, since it may be done with a single heart, and also with a double one, He has seasonably added in this passage: Judge not, that you be not judged. For with what judgment ye judge, you shall be judged, and with what measure ye mete, it shall be measured to you again. In this passage, I am of opinion that we are taught nothing else, but that in the case of those actions respecting which it is doubtful with what intention they are done, we are to put the better construction on them. For when it is written, By their fruits you shall know them, the statement has reference to things which manifestly cannot be done with a good intention; such as debaucheries, or blasphemies, or thefts, or drunkenness, and all such things, of which we are permitted to judge, according to the apostle's statement: For what have I to do to judge them also that are without? Do not ye judge them that are within? But concerning the kind of food, because every kind of human food can be taken indiscriminately with a good intention and a single heart, without the vice of concupiscence, the same apostle forbids that they who ate flesh and drank wine be judged by those who abstained from such kinds of sustenance: Let not him that eats, says he, despise him that eats not; and let not him which eats not, judge him that eats. There also he says: Who are you that judges another man's servant? To his own master he stands or falls. For in reference to such matters as can be done with a good and single and noble intention, although they may also be done with an intention the reverse of good, those parties wished, howbeit they were [mere] men, to pronounce judgment upon the secrets of the heart, of which God alone is Judge.

To this category belongs also what he says in another passage: Therefore judge nothing before the time, until the Lord come, who both will bring to light the hidden things of darkness, and will make manifest the thoughts of the hearts: and then shall every man have praise of God. There are therefore certain ambiguous actions, respecting which we are ignorant with what intention they are performed, because they may be done both with a good or with an evil one, of which it is rash to judge, especially for the purpose of condemning. Now the time will come for these to be judged, when the Lord will bring to light the hidden things of darkness, and will make manifest the counsels of the hearts. In another passage also the same apostle says: Some men's aims are manifest beforehand, going before to judgment; and some men they follow after. He calls those sins manifest, with regard to which it is clear with what intention they are done; these go before to judgment, because if a judgment shall follow, it is not rash. But those which are concealed follow, because neither shall they remain hid in their own time. So we must understand with respect to good works also. For he adds to this effect: Likewise also the good works of some are manifest beforehand; and they that are otherwise cannot be hid. Let us judge, therefore, with respect to those which are manifest; but respecting those which are concealed, let us leave the judgment to God: for they also cannot be hid, whether they be good or evil, when the time shall come for them to be manifested.

There are two things, moreover, in which we ought to beware of rash judgment; when it is uncertain with what intention any thing is done; or when it is uncertain what sort of a person he is going to be, who at preset is manifestly either good or bad. If, therefore, any one, for example, complaining of his stomach, would not fast, and you, not believing this, were to attribute it to the vice of gluttony, you would judge rashly. Likewise, if you were to come to know the gluttony and drunkenness as being manifest, and were so to administer reproof as if the man could never be amended and changed, you would nevertheless judge rashly. Let us not therefore reprove those things about which we do not know with what intention they are done; nor let us so reprove those things which are manifest, as that we should despair of a return to a right state of mind; and thus we shall avoid the judgment of which in the present instance it is said, Judge not, that you be not judged.

[AD 500] Desert Fathers on Matthew 7:1-5
There once came from the city of Rome a monk who had held a high place in the palace. He lived near the church in Scetis, and had with him a servant to take care of him. The priest of the church saw that he was weak and knew that he was used to comfort: and so he passed on to him whatever the Lord gave to him or to the church. After he had lived in Scetis for twenty-five years, he became well known as a man of prayer who had the spirit of prophecy. One of the great Egyptian monks heard of his reputation and came to see him in the hope that he would find there a more austere way of life. He came into his cell and greeted him; after they had prayed they sat down. But the Egyptian saw he had soft clothing, and a bed of reeds, and a blanket under him, and a little pillow under his head, and clean feet with sandals, and he was inwardly contemptuous. In Scetis they never used to live like this, but practised sterner austerity. But the old Roman, with his gift of prayer and insight, saw that the Egyptian monk was shocked to the core. So he said to his servant: ‘Make us a good meal today, for this abba who has come.’ He cooked the few vegetables that he had, and they ate at the proper hour: he had a little wine because of his weakness, and they drank that. In the evening they said twelve psalms, and went to sleep afterwards; they did the same in the night. In the morning the Egyptian got up and left, and saying, ‘Pray for me,’ he went away, not at all impressed. When he had gone a little way the old Roman wanted to heal his mind, and sent after him and called him back. He said: ‘What is your province?’ He answered, ‘I am an Egyptian.’ He said, ‘Of what city?’ He answered, ‘Of no city, I never lived in a city.’ He said, ‘Before you were a monk, how did you earn your living?’ He answered, ‘I was a herdsman.’ He said to him, ‘Where did you sleep?’ He answered, ‘In the fields.’ He said, ‘Had you a mattress?’ He answered, ‘Why should I have a mattress for sleeping in a field?’ He said, ‘So how did you sleep?’ He replied, ‘On the ground.’ He said, ‘What did you eat when you were in the fields? What wine did you drink?’ He answered, ‘What kind of food and drink do you find in a field?’ He said, ‘How then did you live?’ He answered, ‘I ate dry bread, and salt fish if there was any, and I drank water.’ Then the Roman said, ‘A hard life,’ and he added, ‘Was there a bath on the farm where you worked?’ The Egyptian said, ‘No: I washed in the river, when I wanted to.’ When the hermit had extracted these answers, and knew how the Egyptian lived and worked before he became a monk, he wanted to help him: and so he described his own past life in the world. ‘This wretch in front of you came from the great city of Rome, where I had an important post at the palace in the Emperor’s service.’ When the Egyptian heard this first sentence, he was moved, and began to listen attentively. He went on, ‘So I left Rome, and came into this desert. I, whom you see, had great houses and wealth and I scorned them, and came to this little cell. I, whom you see, had beds decked with gold, with costly coverings: and instead of them God gave me this bed of reeds and this blanket. My clothes were rich and expensive: and instead of them I wear these tatters.’ He went on, ‘I used to spend much money on my dinner table and instead of it He has given me these few vegetables and this little cup of wine. Many servants used to wait upon me, and instead the Lord has given one man alone to look after me. Instead of a bath I dip my feet in a little bowl of water, and I use sandals because of my infirmity. For the pipe and the lyre and all the varieties of music which used to delight me at dinner I say twelve psalms in the day, and twelve psalms in the night. For the sins which once I committed, I now offer this poor and useless service to God in quietness. See then, abba, do not be scornful of my weakness.’ When the Egyptian had listened to him, he came to his senses and said, ‘I am a fool. I came from a hard life of labour to be at rest in the monk’s way of life and now I have what I didn’t have before. But you have come of your own accord to this hard life, and have left the comforts of the world; you came from honour and wealth to loneliness and poverty.’ So he went away with much profit; and he became his friend, and used to go to the old man for his soul’s good, for Arsenius (this was his name) was a man of discernment, and full of the fragrance of the Holy Spirit.

[AD 1107] Theophylact of Ohrid on Matthew 7:1
He forbids condemning others, but not reproving others. A reproof is for another’s benefit, but condemnation expresses only derision and scorn. You may also understand that the Lord is speaking of one who, despite his own great sins, condemns others who have lesser sins of which God will be the judge.
[AD 1274] Pseudo-Chrysostom on Matthew 7:1-2
Otherwise; He has drawn out thus far the consequences of his injunctions of almsgiving; He now takes up those respecting prayer. And this doctrine is in a sort a continuation of that of the prayer; as though it should run, Forgive us our debts, and then should follow, Judge not, that ye be not judged.

But some explain this place after a sense, as though the Lord did not herein forbid Christians to reprove others out of good will, but only intended that Christians should not despise Christians by making a show of their own righteousness, hating others often on suspicion alone, condemning them, and pursuing private grudges under the show of piety.

But that not even thus should Christians correct Christians is shown by that expression, Judge not. But if they do not thus correct, shall they therefore obtain forgiveness of their sins, because it is said, and ye shall not be judged? For who obtains forgiveness of a former sin, by not adding another thereto? This we have said, desiring to show that this is not here spoken concerning not judging our neighbour who shall sin against God, but who may sin against ourselves. For whoso does not judge his neighbour who has sinned against him, him shall not God judge for his sin, but will forgive him his debt even as he forgave.

[AD 407] John Chrysostom on Matthew 7:2
That is, it is not the other, says Christ, that you condemn, but yourself, and you are making the judgment-seat dreadful to yourself, and the account strict. As then in the forgiveness of our sins the beginnings are from us, so also in this judgment, it is by ourselves that the measures of our condemnation are laid down. You see, we ought not to upbraid nor trample upon them, but to admonish; not to revile, but to advise; not to assail with pride, but to correct with tenderness. For not him, but yourself, do you give over to extreme vengeance, by not sparing him, when it may be needful to give sentence on his offenses.

Do you see, how these two commandments are both easy, and fraught with great blessings to the obedient, even as of evils on the other hand, to the regardless? For both he that forgives his neighbor, has freed himself first of the two from the grounds of complaint, and that without any labor; and he that with tenderness and indulgence inquires into other men's offenses, great is the allowance of pardon, which he has by his judgment laid up beforehand for himself.

What then! say you: if one commit fornication, may I not say that fornication is a bad thing, nor at all correct him that is playing the wanton? Nay, correct him, but not as a foe, nor as an adversary exacting a penalty, but as a physician providing medicines. For neither did Christ say, stay not him that is sinning, but judge not; that is, be not bitter in pronouncing sentence.
[AD 430] Augustine of Hippo on Matthew 7:2
Is it the case, then, that if we shall judge any thing with a rash judgment, God will also judge rashly with respect to us? Or if we shall measure any thing with an unjust measure, is there with God also an unjust measure, according to which it shall be measured to us again? (for by the expression measure also, I suppose the judgment itself is meant.) By no means does God either judge rashly, or recompense to any one with an unjust measure; but it is so expressed, inasmuch as that very same rashness wherewith you punish another must necessarily punish yourself. Unless, perchance, it is to be imagined that injustice does harm in some way to him against whom it goes forth, but in no way to him from whom it goes forth; but nay, it often does no harm to him who suffers the injury, but it must necessarily do harm to him who inflicts it. For what harm did the injustice of the persecutors do to the martyrs? None; but very much to the persecutors themselves. For although some of them were turned from the error of their ways, yet at the time at which they were acting as persecutors, their wickedness was blinding them. So also a rash judgment frequently does no harm to him who is the object of the rash judgment; but to him who judges rashly, the rashness itself must necessarily do harm. According to such a rule, I judge of that saying also: Every one that strikes with the sword shall perish with the sword. For how many take the sword, and yet do not perish with the sword, Peter himself being an instance! But lest any should think that he escaped such punishment by the pardon of his sins (although nothing could be more absurd than to think that the punishment of the sword, which did not befall Peter, could have been greater than that of the cross, which actually befell him), yet what would they say of the malefactors who were crucified with our Lord; for both he who got pardon, got it after he was crucified, and the other did not get it at all? Or had they perhaps crucified all whom they had slain; and did they therefore themselves too deserve to suffer the same thing? It is ridiculous to think so. For what else is meant by the statement, For all they that take the sword shall perish with the sword, but that the soul dies by that very sin, whatever it may be, which it has committed?
[AD 367] Hilary of Poitiers on Matthew 7:3-5
Otherwise; The sin against the Holy Spirit is to take from God power which has influences, and from Christ substance which is of eternity, through whom as God came to man, so shall man likewise1 come to God. As much greater then as is the beam than the mote, so much greater is the sin against the Holy Spirit than all other sins. As when unbelievers object to others carnal sins, and secrete in themselves the burden of that sin, to wit, that they trust not the promises of God, their minds being blinded as their eye might be by a beam.

If they see him but partaking rather largely of food, they become bitter accusers, while they themselves are daily drinking to excess and surfeiting: not knowing, that besides their own sins, they do hereby gather up for themselves a greater flame, and deprive themselves of every plea. For on this point, that your own doings must be strictly inquired into, you yourself hast first made the law, by thus sentencing those of your neighbor. Account it not then to be a grievous thing, if you are also yourself to undergo the same kind of trial.
[AD 407] John Chrysostom on Matthew 7:3-5
Many do this, if they see a Monk having a superfluous garment, or a plentiful meal, they break out into bitter accusation, though themselves daily seize and devour, and suffer from excess of drinking.

And it is to be noted, that whenever He intends to denounce any great sin, He begins with an epithet of reproach, as below, Thou wicked servant, I forgave thee all that debt; (Mat. 18:32.) and so here, Thou hypocrite, cast out first. For each one knows better the things of himself than the things of others, and sees more the things that be great, than the things that be lesser, and loves himself more than his neighbour. Therefore He bids him who is chargeable with many sins, not to be a harsh judge of another's faults, especially if they be small. Herein not forbidding to arraign and correct; but forbidding to make light of our own sins, and magnify those of others. For it behoves you first diligently to examine how great may be your own sins, and then try those of your neighbour; whence it follows, and then shalt thou see clearly to cast the mote out of thy brother's eye.

[AD 407] John Chrysostom on Matthew 7:3-5
Here Christ wants to show the great outrage he has toward people who do such things. For wherever he wants to show that the sin is great and that the punishment and anger for it is great, he begins with an open rebuke. For example, to show that he was provoked to anger he said to the man who was demanding the hundred silver coins, “Wicked slave, I forgave you all that debt.” In the same way also here he says, “Hypocrite.” For the verdict that one’s brother needs a splinter taken from his eye does not come from concern but from contempt for humanity. Even while one is putting on a mask of love toward others, one is actually performing a deed of consummate evil by inflicting numerous criticisms and accusations on close companions, thereby usurping the rank of teacher when one is not even worthy to be a disciple. For this reason he called this one “hypocrite.”So then, you who are so spiteful as to see even the little faulty details in others, how have you become so careless with your own affairs that you avoid your own major faults? “First remove the plank from your eye.” You see that Jesus does not forbid judging but commands that one first remove the plank from one’s own eye. One may then set right the issues relating to others. For each person knows his own affairs better than others know them. And each one sees major faults easier than smaller ones. And each one loves oneself more than one’s neighbor. So if you are really motivated by genuine concern, I urge you to show this concern for yourself first, because your own sin is both more certain and greater.

(Vers. 3-5.) But why do you see the speck in your brother's eye, and not see the beam in your own eye? Or how can you say to your brother, 'Brother, let me remove the speck from your eye,' while the beam is in your own eye? Hypocrite, first remove the beam from your own eye, and then you will see clearly to remove the speck from your brother's eye. He speaks of those who, while being subject to mortal sin themselves, do not overlook minor sins of their brothers: straining out a gnat and swallowing a camel (Matthew 23). Therefore, those who hypocritically pretend to be just, as we said above, are called hypocrites, who, while they have a beam in their own eye, look at the speck in their brother's eye.

[AD 430] Augustine of Hippo on Matthew 7:3
And inasmuch as the Lord is admonishing us in this passage with respect to rash and unjust judgment,— for He wishes that whatever we do, we should do it with a heart that is single and directed toward God alone; and inasmuch as, with respect to many things, it is uncertain with what intention they are done, regarding which it is rash to judge; inasmuch, moreover, as those parties especially judge rashly respecting things that are uncertain, and readily find fault, who love rather to censure and to condemn than to amend and to improve, which is a fault arising either from pride or from envy; therefore He has subjoined the statement: And why do you behold the mote that is in your brother's eye, but considerest not the beam that is in your own eye? So that if perchance, for example, he has transgressed in anger, you should find fault in hatred; there being, as it were, as much difference between anger and hatred as between a mote and a beam. For hatred is inveterate anger, which, as it were simply by its long duration, has acquired so great strength as to be justly called a beam. Now, it may happen that, though you are angry with a man, you wish him to be turned from his error; but if you hate a man, you cannot wish to convert him.
[AD 430] Augustine of Hippo on Matthew 7:3-5
(De. Civ. Dei, xxi. 11.) Some say, How is it true that Christ says, And with what measure ye shall mete it shall be measured to you again, if temporal sin is to be punished by eternal suffering? They do not observe that it is not said the same measure, because of the equal space of time, but because of the equal retribution—namely, that he who has done evil should suffer evil, though even in that sense it might be said of that of which the Lord spoke here, namely of judgments and condemnations. Accordingly, he that judges and condemns unjustly, if he is judged and condemned, justly receives in the same measure though not the same thing that he gave; by judgment he did what was unjust, by judgment he suffers what is just.

(Serm. in Mont. ii. 18.) The Lord having admonished us concerning hasty and unjust judgment; and because that they are most given to rash judgment, who judge concerning things uncertain; and they most readily find fault, who love rather to speak evil and to condemn than to cure and to correct; a fault that springs either from pride or jealousy—therefore He subjoins, Why seest thou the mote in thy brother's eye, and seest not the beam in thy own eye?

(ubi sup.) As if he perhaps have sinned in anger, and you correct him with settled hate. For as great as is the difference between a beam and a mote, so great is the difference between anger and hatred. For hatred is anger become inveterate. It may be if you are angry with a man that you would have him amend, not so if you hate him.

(Serm. in Mont. ii. 19.) When then we are brought under the necessity of finding fault with any, let us first consider whether the sin be such as we have never had; secondly that we are yet men, and may fall into it; then, whether it be one that we have had, and are now without, and then let our common frailty come into our mind, that pity and not hate may go before correction. Should we find ourselves in the same fault, let us not reprove, but groan with the offender, and invite him to struggle with us. Seldom indeed and in cases of great necessity is reproof to be employed; and then only that the Lord may be served and not ourselves.

(Serm. in Mont. ii. 19.) For to reprove sin is the duty of the good, which when the bad do, they act a part, dissembling their own character, and assuming one that does not belong to them.

(ubi sup.) For having removed from our own eye the beam of envy, of malice, or hypocrisy, we shall see clearly to cast the beam out of our brother's eye.

Source: Catena Aurea by Aquinas
[AD 430] Augustine of Hippo on Matthew 7:3-5
The word hypocrite is aptly employed here, since the denouncing of evils is best viewed as a matter only for upright persons of goodwill. When the wicked engage in it, they are like impersonators, masqueraders, hiding their real selves behind a mask, while they portray another’s character through the mask. The word hypocrites in fact signifies pretenders. Hence we ought especially to avoid that meddlesome class of pretenders who under the pretense of seeking advice undertake the censure of all kinds of vices. They are often moved by hatred and malice.Rather, whenever necessity compels one to reprove or rebuke another, we ought to proceed with godly discernment and caution. First of all, let us consider whether the other fault is such as we ourselves have never had or whether it is one that we have overcome. Then, if we have never had such a fault, let us remember that we are human and could have had it. But if we have had it and are rid of it now, let us remember our common frailty, in order that mercy, not hatred, may lead us to the giving of correction and admonition. In this way, whether the admonition occasions the amendment or the worsening of the one for whose sake we are offering it (for the result cannot be foreseen), we ourselves shall be made safe through singleness of eye. But if on reflection we find that we ourselves have the same fault as the one we are about to reprove, let us neither correct nor rebuke that one. Rather, let us bemoan the fault ourselves and induce that person to a similar concern, without asking him to submit to our correction.

[AD 500] Desert Fathers on Matthew 7:3-5
This story was told: There were three friends, serious men, who became monks. One of them chose to make peace between men who were at odds, as it is written, ‘Blessed are the peacemakers’ (Matt. 5:9). The second chose to visit the sick. The third chose to go away to be quiet in solitude. Now the first, toiling among contentions, was not able to settle all quarrels and, overcome with weariness, he went to him who tended the sick, and found him also failing in spirit and unable to carry out his purpose. So the two went away to see him who had withdrawn into the desert, and they told him their troubles. They asked him to tell them how he himself had fared. He was silent for a while, and then poured water into a vessel and said, ‘Look at the water,’ and it was murky. After a little while he said again, ‘See now, how clear the water has become.’ As they looked into the water they saw their own faces, as in a mirror. Then he said to them, ‘So it is with anyone who lives in a crowd; because of the turbulence, he does not see his sins: but when he has been quiet, above all in solitude, then he recognizes his own faults.’

Otherwise; This is spoken to the doctors. For every sin is either a great or a small sin according to the character of the sinner. If he is a laie, it is small and a mote in comparison of the sin of a priest, which is the beam.

That is, with what face can you charge your brother with sin, when yourself are living in the same or a yet greater sin?

Otherwise; How sayest thou to thy brother; that is, with what purpose? From charity, that you may save your neighbour? Surely not, for you would first save yourself. You desire therefore not to heal others, but by good doctrine to cover bad life, and to gain praise of learning from men, not the reward of edifying from God, and you are a hypocrite; as it follows, Thou hypocrite, cast first the beam out of thine own eye.

[AD 430] Augustine of Hippo on Matthew 7:4
First cast the hatred away from you, and then, but not before, shall you be able to amend him whom you love. And He well says, Thou hypocrite. For to make complaint against vices is the duty of good and benevolent men; and when bad men do it, they are acting a part which does not belong to them; just like hypocrites, who conceal under a mask what they are, and show themselves off in a mask what they are not. Under the designation hypocrites, therefore, you are to understand pretenders. And there is, in fact, a class of pretenders much to be guarded against, and troublesome, who, while they take up complaints against all kinds of faults from hatred and spite, also wish to appear counsellors. And therefore we must piously and cautiously watch, so that when necessity shall compel us to find fault with or rebuke any one, we may reflect first whether the fault is such as we have never had, or one from which we have now become free; and if we have never had it, let us reflect that we are men, and might have had it; but if we have had it, and are now free from it, let the common infirmity touch the memory, that not hatred but pity may go before that fault-finding or administering of rebuke: so that whether it shall serve for the conversion of him on whose account we do it, or for his perversion (for the issue is uncertain), we at least from the singleness of our eye may be free from care. If, however, on reflection, we find ourselves involved in the same fault as he is whom we were preparing to censure, let us not censure nor rebuke; but yet let us mourn deeply over the case, and let us invite him not to obey us, but to join us in a common effort.

For in regard also to what the apostle says—Unto the Jews I became as a Jew, that I might gain the Jews; to them that are under the law, as under the law (not being under the law), that I might gain them that are under the law; to them that are without law, as without law (being not without law to God, but under the law to Christ), that I might gain them that are without law. To the weak became I as weak, that I might gain the weak: I am made all things to all men, that I might gain all,— he did not certainly so act in the way of pretence, as some wish it to be understood, in order that their detestable pretence may be fortified by the authority of so great an example; but he did so from love, under the influence of which he thought of the infirmity of him whom he wished to help as if it were his own. For this he also lays as the foundation beforehand, when he says: For although I be free from all men, yet have I made myself servant unto all, that I might gain the more. And that you may understand this as being done not in pretence, but in love, under the influence of which we have compassion for men who are weak as if we were they, he thus admonishes us in another passage, saying, Brethren, you have been called unto liberty; only use not liberty for an occasion to the flesh, but by love serve one another. And this cannot be done, unless each one reckon the infirmity of another as his own, so as to bear it with equanimity, until the party for whose welfare he is solicitous is freed from it.
[AD 407] John Chrysostom on Matthew 7:5
Here His will is to signify the great wrath, which He has against them that do such things. For so, wheresoever He would indicate that the sin is great, and the punishment and wrath in store for it grievous, He begins with a reproach. As then unto him that was exacting the hundred pence, He said in His deep displeasure, Thou wicked servant, I forgave you all that debt; Matthew 18:32 even so here also, Thou hypocrite. For not of protecting care comes such a judgment, but of ill will to man; and while a man puts forward a mask of benevolence, he is doing a work of the utmost wickedness, causing reproaches without ground, and accusations, to cleave unto his neighbors, and usurping a teacher's rank, when he is not worthy to be so much as a disciple. On account of this He called him hypocrite. For thou, who in other men's doings art so bitter, as to see even the little things; how have you become so remiss in your own, as that even the great things are hurried over by you?

First cast out the beam out of your own eye.

Do you see, that He forbids not judging, but commands to cast out first the beam from your eye, and then to set right the doings of the rest of the world? For indeed each one knows his own things better than those of others; and sees the greater rather than the less; and loves himself more than his neighbor. Wherefore, if you do it out of guardian care, I bid you care for yourself first, in whose case the sin is both more certain and greater. But if you neglect yourself, it is quite evident that neither do you judge your brother in care for him, but in hatred, and wishing to expose him. For what if he ought to be judged? It should be by one who commits no such sin, not by you.

Thus, because He had introduced great and high doctrines of self denial, lest any man should say, it is easy so to practise it in words; He willing to signify His entire confidence, and that He was not chargeable with any of the things that had been mentioned, but had duly fulfilled all, spoke this parable. And that, because He too was afterwards to judge, saying, Woe unto you, Scribes and Pharisees, hypocrites. Matthew 23:1 Yet was not he chargeable with what has been mentioned; for neither did He pull out a mote, nor had He a beam on His eyes, but being clean from all these, He so corrected the faults of all. For it is not at all meet, says He, to judge others, when one is chargeable with the same things. And why marvel at His establishing this law, when even the very thief knew it upon the cross, saying to the other thief, Do you not fear God, seeing we are in the same condemnation; expressing the same sentiments with Christ?

But you, so far from casting out your own beam, dost not even see it, but another's mote thou not only see, but also judgest, and essayest to cast it out; as if any one seized with a grievous dropsy, or indeed with any other incurable disease, were to neglect this, and find fault with another who was neglecting a slight swelling. And if it be an evil not to see one's own sins, it is a twofold and threefold evil to be even sitting in judgment on others, while men themselves, as if past feeling, are bearing about beams in their own eyes: since no beam is so heavy as sin.

His injunction therefore in these words is as follows, that he who is chargeable with countless evil deeds, should not be a bitter censor of other men's offenses, and especially when these are trifling. He is not overthrowing reproof nor correction, but forbidding men to neglect their own faults, and exult over those of other men.

For indeed this was a cause of men's going unto great vice, bringing in a twofold wickedness. For he, whose practice it had been to slight his own faults, great as they were, and to search bitterly into those of others, being slight and of no account, was spoiling himself two ways: first, by thinking lightly of his own faults; next, by incurring enmities and feuds with all men, and training himself every day to extreme fierceness, and want of feeling for others.
[AD 430] Augustine of Hippo on Matthew 7:5
Rarely, therefore, and in a case of great necessity, are rebukes to be administered; yet in such a way that even in these very rebukes we may make it our earnest endeavour, not that we, but that God, should be served. For He, and none else, is the end: so that we are to do nothing with a double heart, removing from our own eye the beam of envy, or malice, or pretence, in order that we may see to cast the mote out of a brother's eye. For we shall see it with the dove's eyes—such eyes as are declared to belong to the spouse of Christ, whom God has chosen for Himself a glorious Church, not having spot or wrinkle, i.e. pure and guileless.
[AD 1107] Theophylact of Ohrid on Matthew 7:5
. He who would rebuke others ought to be blameless himself. If he himself has a plank in his eye, that is, some great sin, and he finds fault with another who has only a speck, he causes that man to be even more shameless in his sin. The Lord shows that he who has sinned greatly is not even able to see clearly the sin of his brother. For how could one who has a plank in his eye even see another man who is only slightly injured.
[AD 100] Didache on Matthew 7:6
Now concerning the Thanksgiving (Eucharist), thus give thanks.

And concerning the broken bread: We thank You, our Father, for the life and knowledge which You made known to us through Jesus Your Servant; to You be the glory forever. Even as this broken bread was scattered over the hills, and was gathered together and became one, so let Your Church be gathered together from the ends of the earth into Your kingdom; for Yours is the glory and the power through Jesus Christ forever. But let no one eat or drink of your Thanksgiving (Eucharist), but they who have been baptized into the name of the Lord; for concerning this also the Lord has said, Give not that which is holy to the dogs. [Matthew 7:6]

But after you are filled, thus give thanks: We thank You, holy Father, for Your holy name which You caused to tabernacle in our hearts, and for the knowledge and faith and immortality, which You made known to us through Jesus Your Servant; to You be the glory forever. You, Master almighty, created all things for Your name's sake; You gave food and drink to men for enjoyment, that they might give thanks to You; but to us You freely gave spiritual food and drink and life eternal through Your Servant. Before all things we thank You that You are mighty; to You be the glory forever. Remember, Lord, Your Church, to deliver it from all evil and to make it perfect in Your love, and gather it from the four winds, sanctified for Your kingdom which You have prepared for it; for Yours is the power and the glory forever. Let grace come, and let this world pass away. Hosanna to the God (Son) of David! If any one is holy, let him come; if any one is not so, let him repent. Maran atha. Amen. But permit the prophets to make Thanksgiving as much as they desire.

Yet surely further on, it will be said, He commanded, What you have heard in the ear, that preach ye upon the housetops. Matthew 10:27 But this is in no wise contrary to the former. For neither in that place did He simply command to tell all men, but to whom it should be spoken, to them He bade speak with freedom. And by dogs here He figuratively described them that are living in incurable ungodliness, and affording no hope of change for the better; and by swine, them that abide continually in an unchaste life, all of whom He has pronounced unworthy of hearing such things. Paul also, it may be observed, declared this when He said, But a natural man receives not the things of the Spirit, for they are foolishness unto him. And in many other places too He says that corruption of life is the cause of men's not receiving the more perfect doctrines. Wherefore He commands not to open the doors to them; for indeed they become more insolent after learning. For as to the well-disposed and intelligent, things appear venerable when revealed, so to the insensible, when they are unknown rather. Since then from their nature, they are not able to learn them, let the thing be hidden, says He, that at least for ignorance they may reverence them. For neither does the swine know at all what a pearl is. Therefore since he knows not, neither let him see it, lest he trample under foot what he knows not.

For nothing results, beyond greater mischief to them that are so disposed when they hear; for both the holy things are profaned by them, not knowing what they are; and they are the more lifted up and armed against us. For this is meant by, lest they trample them under their feet, and turn again and rend you.

Nay, surely, says one, they ought to be so strong as to remain equally impregnable after men's learning them, and not to yield to other people occasions against us. But it is not the things that yield it, but that these men are swine; even as when the pearl is trampled under foot, it is not so trampled, because it is really contemptible, but because it fell among swine.

And full well did He say, turn again and rend you: for they feign gentleness, so as to be taught: then after they have learned, quite changing from one sort to another, they jeer, mock and deride us, as deceived persons. Therefore Paul also said to Timothy, 2 Timothy 4:15 Of whom also beware; for he has greatly withstood our words; and again in another place, From such turn away, and, A man that is an heretic, after the first and second admonition, reject.

It is not, you see, that those truths furnish them with armor, but they become fools in this way of their own accord, being filled with more willfulness. On this account it is no small gain for them to abide in ignorance, for so they are not such entire scorners. But if they learn, the mischief is twofold. For neither will they themselves be at all profited thereby, but rather the more damaged, and to you they will cause endless difficulties.

Let them hearken, who shamelessly associate with all, and make the awful things contemptible. For the mysteries we too therefore celebrate with closed doors, and keep out the uninitiated, not for any weakness of which we have convicted our rites, but because the many are as yet imperfectly prepared for them. For this very reason He Himself also discoursed much unto the Jews in parables, because they seeing saw not. For this, Paul likewise commanded to know how we ought to answer every man. Colossians 4:6
[AD 420] Jerome on Matthew 7:6
(Verse 6) Do not give what is holy to the dogs. Holy, it is the bread of the children. Therefore, we should not take the bread of the children and give it to the dogs.

Do not cast your pearls before swine, lest they trample them under their feet, and turn and tear you to pieces. The pig does not appreciate ornamentation, as it wallows in the mire. And according to the Proverbs of Solomon: If he has a golden circle, he is found to be more vile. (Prov. XI, 22). Some interpret them as dogs who return to the vomit of their sins after believing in Christ: but they interpret pigs as those who have not yet believed in the Gospel, and who wallow in the mire of unbelief and vice. Therefore, it is not fitting for men of this kind to quickly believe the Gospel pearl, lest they trample on it and, once converted, begin to scatter us.

Source: Commentary on Matthew
[AD 430] Augustine of Hippo on Matthew 7:6
(ubi sup.) For having removed from our own eye the beam of envy, of malice, or hypocrisy, we shall see clearly to cast the beam out of our brother's eye.

(ubi sup.) Because the simplicity to which He had been directing in the foregoing precepts might lead some wrongly to conclude that it was equally wrong to hide the truth as to utter what was false, He well adds, Give not that which is holy to the dogs, and cast not your pearls before swine.

(Serm. in Mont. ii. 20.) Let us see now what is the holy thing, what are the dogs, what the pearls, what the swine? The holy thing is all that it were impiety to corrupt; a sin which may be committed by the will, though the thing itself be undone. The pearls are all spiritual things that are to be highly esteemed. Thus though one and the same thing may be called both the holy thing and a pearl, yet it is called holy because it is not to be corrupted; and called a pearl because it is not to be contemned.

(ubi sup.) The dogs are those that assault the truth; the swine we may not unsuitably take for those that despise the truth. Therefore because dogs leap forth to rend in pieces, and what they rend, suffer not to continue whole, He said, Give not that which is holy to the dogs; because they strive to the utmost of their power to destroy the truth. The swine though they do not assault by biting as dogs, yet do they defile by trampling upon, and therefore He said, Cast not your pearls before swine.

(ubi sup.) That which is despised is said to be trodden under foot: hence it is said, Lest perchance they tread them under foot.

(ubi sup.) That which follows, Turn again and rend you, He means not the pearls themselves, for these they tread under foot, and when they turn again that they may hear something further, then they rend him by whom the pearls on which they had trode had been cast. For you will not easily find what will please him who has despised things got by great toil. Whoever then undertake to teach such, I see not how they shall not be trode upon and rent by those they teach.

(ubi sup.) We must be careful therefore not to explain ought to him who does not receive it; for men the rather seek that which is hidden than that which is opened. He either attacks from ferocity as a dog, or overlooks from stupidity as swine. But it does not follow that if the truth be kept hid, falsehood is uttered. The Lord Himself who never spoke falsely, yet sometimes concealed the truth, as in that, I have yet many things to say unto you, the which ye are not now able to bear. (John 16:12.) But if any is unable to receive these things because of his filthiness, we must first cleanse him as far as lays in our power either by word or deed. But in that the Lord is found to have said some things which many who heard Him did not receive, but either rejected or contemned them, we are not to think that therein He gave the holy thing to the dogs, or cast His pearls before swine. He gave to those who were able to receive, and who were in the company, whom it was not fit should be neglected for the uncleanness of the rest. And though those who tempted Him might perish in those answers which He gave to them, yet those who could receive them by occasion of these inquiries heard many useful things. He therefore who knows what should be answered ought to make answer, for their sakes at least who might fall into despair should they think that the question proposed is one that cannot be answered. But this only in the case of such matters as pertain to instruction of salvation; of things superfluous or harmful nothing should be said; but it should then be explained for what reason we ought not to make answer in such points to the enquirer.

But inasmuch as the word guileless may mislead some who are desirous of obeying God's precepts, so that they may think it wrong, at times, to conceal the truth, just as it is wrong at times to speak a falsehood, and inasmuch as in this way—by disclosing things which the parties to whom they are disclosed are unable to bear—they may do more harm than if they were to conceal them altogether and always, He very rightly adds: Give not that which is holy to the dogs, neither cast ye your pearls before swine, lest they trample them under their feet, and turn again and rend you. For the Lord Himself, although He never told a lie, yet showed that He was concealing certain truths, when He said, I have yet many things to say unto you, but you cannot bear them now. And the Apostle Paul, too, says: And I, brethren, could not speak unto you as unto spiritual, but as unto carnal, even as unto babes in Christ. I have fed you with milk, and not with meat: for hitherto you were not able to bear it, neither yet now are you able. For you are yet carnal.
68. Now, in this precept by which we are forbidden to give what is holy to the dogs, and to cast our pearls before swine, we must carefully require what is meant by holy, what by pearls, what by dogs, what by swine. A holy thing is something which it is impious to violate and to corrupt; and the very attempt and wish to commit that crime is held to be criminal, although that holy thing should remain in its nature inviolable and incorruptible. By pearls, again, are meant whatever spiritual things we ought to set a high value upon, both because they lie hidden in a secret place, are as it were brought up out of the deep, and are found in wrappings of allegory, as it were in shells that have been opened. We may therefore legitimately understand that one and the same thing may be called both holy and a pearl: but it gets the name of holy for this reason, that it ought not to be corrupted; of a pearl for this reason, that it ought not to be despised. Every one, however, endeavours to corrupt what he does not wish to remain uninjured: but he despises what he thinks worthless, and reckons to be as it were beneath himself; and therefore whatever is despised is said to be trampled on. And hence, inasmuch as dogs spring at a thing in order to tear it in pieces, and do not allow what they are tearing in pieces to remain in its original condition, Give not, says He, that which is holy unto the dogs: for although it cannot be torn in pieces and corrupted, and remains unharmed and inviolable, yet we must think of what is the wish of those parties who bitterly and in a most unfriendly spirit resist, and, as far as in them lies, endeavour, if it were possible, to destroy the truth. But swine, although they do not, like dogs, fall upon an object with their teeth, yet by recklessly trampling on it defile it: Do not therefore cast your pearls before swine, lest they trample them under their feet, and turn again and rend you. We may therefore not unsuitably understand dogs as used to designate the assailants of the truth, swine the despisers of it.

But when He says, they turn again and rend you, He does not say, they rend the pearls themselves. For by trampling on them, just when they turn in order that they may hear something more, they yet rend him by whom the pearls have just been cast before them which they have trampled on. For you would not easily find out what pleasure the man could have who has trampled pearls under foot, i.e. has despised divine things whose discovery is the result of great labour. But in regard to him who teaches such parties, I do not see how he would escape being rent in pieces through their anger and wrathfulness. Moreover, both animals are unclean, the dog as well as the swine. We must therefore be on our guard, lest anything should be opened up to him who does not receive it: for it is better that he should seek for what is hidden, than that he should either attack or slight at what is open. Neither, in fact, is any other cause found why they do not receive those things which are manifest and of importance, except hatred and contempt, the one of which gets them the name of dogs, the other that of swine. And all this impurity is generated by the love of temporal things, i.e. by the love of this world, which we are commanded to renounce, in order that we may be able to be pure. The man, therefore, who desires to have a pure and single heart, ought not to appear to himself blameworthy, if he conceals anything from him who is unable to receive it. Nor is it to be supposed from this that it is allowable to lie: for it does not follow that when truth is concealed, falsehood is uttered. Hence, steps are to be taken first, that the hindrances which prevent his receiving it may be removed; for certainly if pollution is the reason he does not receive it, he is to be cleansed either by word or by deed, as far as we can possibly do it.

Then, further, when our Lord is found to have made certain statements which many who were present did not accept, but either resisted or despised, He is not to be thought to have given that which is holy to the dogs, or to have cast pearls before swine: for He did not give such things to those who were not able to receive them, but to those who were able, and were at the same time present; whom it was not meet that He should neglect on account of the impurity of others. And when tempters put questions to Him, and He answered them, so that they might have nothing to gainsay, although they might pine away from the effects of their own poisons, rather than be filled with His food, yet others, who were able to receive His teaching, heard to their profit many things in consequence of the opportunity created by these parties. I have said this, lest any one, perhaps, when he is not able to reply to one who puts a question to him, should seem to himself excused, if he should say that he is unwilling to give that which is holy to the dogs, or to cast pearls before swine. For he who knows what to answer ought to do it, even for the sake of others, in whose minds despair arises, if they believe that the question proposed cannot be answered: and this in reference to matters that are useful, and that belong to saving instruction. For many things which may be the subject of inquiry on the part of idle people are needless and vain, and often hurtful, respecting which, however, something must be said; but this very point is to be opened up and explained, viz. why such things ought not to form the subject of inquiry. In reference, therefore, to things that are useful, we ought sometimes to give a reply to what is asked of us: just as the Lord did, when the Sadducees had asked Him about the woman who had seven husbands, to which of them she would belong in the resurrection. For He answered that in the resurrection they will neither marry, nor be given in marriage, but will be as the angels in heaven. But sometimes, he who asks is to be asked something else, by telling which he would answer himself as to the matter he asked about; but if he should refuse to make a statement, it would not seem to those who are present unfair, if he himself should not hear anything as to the matter he inquired about. For those who put the question, tempting Him, whether tribute was to be paid, were asked another question, viz. whose image the money bore which was brought forward by themselves; and because they told what they had been asked, i.e. that the money bore the image of Cæsar, they gave a kind of answer to themselves in reference to the question they had asked the Lord: and accordingly from their answer He drew this inference, Render therefore unto Cæsar the things which are Cæsar's, and unto God the things that are God's. When, however, the chief priests and elders of the people had asked by what authority He was doing those things, He asked them about the baptism of John: and when they would not make a statement which they saw to be against themselves, and yet would not venture to say anything bad about John, on account of the bystanders, Neither tell I you, says He, by what authority I do these things; a refusal which appeared most just to the bystanders. For they said they were ignorant of that which they really knew, but did not wish to tell. And, in truth, it was right that they who wished to have an answer to what they asked, should themselves first do what they required to be done toward them; and if they had done this, they would certainly have answered themselves. For they themselves had sent to John, asking who he was; or rather they themselves, being priests and Levites, had been sent, supposing that he was the very Christ, but he said that he was not, and gave forth a testimony concerning the Lord: a testimony respecting which if they chose to make a confession, they would teach themselves by what authority as the Christ He was doing those things; which as if ignorant of they had asked, in order that they might find an avenue for calumny.
[AD 430] Augustine of Hippo on Matthew 7:6
Now in this precept we are forbidden to give a holy thing to dogs or to cast pearls before swine. We must diligently seek to determine the gravity of these words: holy, pearls, dogs and swine. A holy thing is whatever it would be impious to profane or tear apart. Even a fruitless attempt to do so makes one already guilty of such impiety, though the holy thing may by its very nature remain inviolable and indestructible. Pearls signify all spiritual things that are worthy of being highly prized. Because these things lie hidden in secret, it is as though they were being drawn up from the deep. Because they are found in the wrappings of allegories, it is as though they were contained within shells that have been opened. It is clear therefore that one and the same thing can be called both a holy thing and a pearl. It can be called a holy thing because it ought not to be destroyed and a pearl because it ought not to be despised. One tries to destroy what one does not wish to leave intact. One despises what is deemed worthless, as if beneath him. Hence, whatever is despised is said to be trampled under foot.You know that dogs rush madly to tear apart whatever they attack, leaving nothing intact. Hence the Lord says, “Do not give to dogs what is holy.” For although the holy thing itself cannot be shattered or destroyed but remains intact and unharmed, what must be considered is the desire of those who resist the truth with the utmost violence and bitterness. They do everything in their power to destroy what is holy, as if its destruction were possible. Although swine—unlike dogs—do not attack by biting, they befoul a thing by trampling all over it. Therefore “do not cast your pearls before swine, lest they trample them under their feet and turn and attack you.” Thus we may rightly understand that these words (dogs and swine) are now used to designate respectively those who assail the truth and those who resist it.
By saying “lest they turn and tear you apart” Jesus does not say, “Lest they tear apart the pearls themselves.” For by trampling on the pearls even when they turn around to hear something further, they lacerate the one who cast the pearls they have already trampled upon. Of course, it would not be easy to find anything that would please one who would trample on pearls. Who could please one who despises divine truth revealed at such great cost? But I do not see how anyone who tries to teach such people will not themselves be torn apart by indignation and disgust, for both dogs and swine are unclean animals. Therefore we must be careful not to reveal anything to one who cannot bear it, for it is better that one make a search for what is concealed than assail or despise what is revealed. Indeed, it is only through hatred or contempt that people refuse to accept truths of manifest importance. Hence for one reason some are called dogs, and for the other reason some are called swine.

[AD 1107] Theophylact of Ohrid on Matthew 7:6
The dogs are the unbelievers and the swine are believers who lead a filthy and shameful way of life. One ought not therefore to speak of the mysteries to the unbelievers, nor speak brilliant and lustrous words of theology to those who are unclean. For the swine trample them underfoot, that is, despise what is said, while the dogs turn on us and tear us limb from limb. This is what those so-called philosophers do; when they hear that God was crucified, they stab us with their syllogisms, reasoning with their sophistry that this is impossible.
[AD 1274] Pseudo-Chrysostom on Matthew 7:6
Otherwise; The Lord had commanded us to love our enemies, and to do good to those that sin against us. That from this Priests might not think themselves obliged to communicate also the things of God to such, He checked any such thought saying, Give not that which is holy to the dogs; as much as to say, I have bid you love your enemies, and do them good out of your temporal goods, but not out of My spiritual goods, without distinction. For they are your brethren by nature but not by faith, and God gives the good things of this life equally to the worthy and the unworthy, but not so spiritual graces.

Otherwise; That which is holy denotes baptism, the grace of Christ's body, and the like; but the mysteries of the truth are intended by the pearls. For as pearls are inclosed in shells, and such in the deeps of the sea, so the divine mysteries inclosed in words are lodged in the deep meaning of Holy Scripture.

Otherwise; The dog and the swine are unclean animals; the dog indeed in every respect, as he neither chews the cud, nor divides the hoof; but swine in one respect only, seeing they divide the hoof, though they do not chew the cud. Hence I think that we are to understand by the dog, the Gentiles who are altogether unclean, both in their life, and in their faith; but by the swine are to be understood heretics, because they seem to call upon the name of the Lord. Give not therefore that which is holy to the dogs, for that baptism and the other sacraments are not to be given but to them that have the faith. In like manner the mysteries of the truth, that is, the pearls, are not to be given but to such as desire the truth and live with human reason. If then you cast them to the swine, that is, to such as are grovelling in impurity of life, they do not understand their preciousness, but value them like to other worldly fables, and tread them under foot with their carnal life.

Or; The swine not only trample upon the pearls by their carnal life, but after a little they turn, and by disobedience rend those who offend them. Yea often when offended they bring false accusation against them as sowers of new dogmas. The dogs also having trode upon holy things by their impure actions, by their disputings rend the preacher of truth.

With good reason He forbade pearls to be given to swine. For if they are not to be set before swine that are the less unclean, how much more are they to be withheld from dogs that are so much more unclean. But respecting the giving that which is holy, we cannot hold the same opinion; seeing we often give the benediction to Christians who live as the brutes; and that not because they deserve to receive it, but lest perchance being more grievously offended they should perish utterly.

[AD 407] John Chrysostom on Matthew 7:7
For inasmuch as He had enjoined things great and marvellous, and had commanded men to be superior to all their passions, and had led them up to Heaven itself, and had enjoined them to strive after the resemblance, not of angels and archangels, but (as far as was possible) of the very Lord of all; and had bidden His disciples not only themselves duly to perform all this, but also to correct others, and to distinguish between the evil and them that are not such, the dogs and them that are not dogs (although there be much that is hidden in men):— that they might not say, these things are grievous and intolerable, (for indeed in the sequel Peter did utter some such things, saying, Who can be saved? and again, If the case of the man be so, it is not good to marry): in order therefore that they might not now likewise say so; as in the first place even by what had gone before He had proved it all to be easy, setting down many reasons one upon another, of power to persuade men: so after all He adds also the pinnacle of all facility, devising as no ordinary relief to our toils, the assistance derived from persevering prayers. Thus, we are not ourselves, says He, to strive alone, but also to invoke the help from above: and it will surely come and be present with us, and will aid us in our struggles, and make all easy. Therefore He both commanded us to ask, and pledged Himself to the giving.

However, not simply to ask did He command us, but with much assiduity and earnestness. For this is the meaning of seek. For so he that seeks, putting all things out of his mind, is taken up with that alone which is sought, and forms no idea of any of the persons present. And this which I am saying they know, as many as have lost either gold, or servants, and are seeking diligently after them.

By seeking, then, He declared this; by knocking, that we approach with earnestness and a glowing mind.

Despond not therefore, O man, nor show less of zeal about virtue, than they do of desire for wealth. For things of that kind you have often sought and not found, but nevertheless, though thou know this, that you are not sure to find them, you put in motion every mode of search; but here, although having a promise that you will surely receive, thou dost not show even the smallest part of that earnestness. And if you dost not receive straightway, do not even thus despair. For to this end He said, knock, to signify that even if He should not straightway open the door, we are to continue there.
[AD 407] John Chrysostom on Matthew 7:7-8

However, Jesus did not simply command us to ask but to ask with great concern and concentration—for this is the meaning of the word he used for “seek.” For those who are seeking put aside everything else from their minds. They become concerned only with the thing that they are seeking and pay no attention at all to the circumstances. Even those who are looking for gold or servants that have been lost understand what I am saying. So this is what he meant by seeking. But by knocking Jesus meant that we approach God with intensity and passion. Therefore, O mortal, do not give up. Do not show less eagerness for virtue than desire for possessions. For you frequently sought possessions but did not find them. Nevertheless, although you knew that you could not guarantee that you would find them, you used every means of searching for them. Yet even though in this case you have a promise that you surely will receive, you do not even demonstrate the smallest fraction of that same eagerness. But if you do not receive immediately, do not despair in this way. For it is because of this that Jesus said “knock” to show that even if he does not open the door immediately we should remain at the door knocking.

Or if he asks for a fish, will give him a serpent? He shows what we should seek, who had forbidden earthly things to be asked for. If it is given to the one who asks, and the one who seeks finds, and to the one who knocks it is opened, then it is clear that the one who has not been given, and the one who has not found, and the one to whom it has not been opened, has not asked, sought, and knocked properly. Let us therefore knock at the door of Christ, of which it is said: This is the gate of the Lord, the just shall enter into it (Ps.

Since, therefore, a command had been given that what is holy should not be given to dogs, and pearls should not be cast before swine, a hearer might object and say, conscious of his own ignorance and weakness, and hearing a command addressed to him, that he should not give what he felt that he himself had not yet received—might (I say) object and say, What holy thing do you forbid me to give to the dogs, and what pearls do you forbid me to cast before swine, while as yet I do not see that I possess such things? Most opportunely He has added the statement: Ask, and it shall be given you; seek, and you shall find; knock, and it shall be opened unto you. For every one that asks receives; and he that seeks finds; and to him that knocks it shall be opened. The asking refers to the obtaining by request soundness and strength of mind, so that we may be able to discharge those duties which are commanded; the seeking, on the other hand, refers to the finding of the truth. For inasmuch as the blessed life is summed up in action and knowledge, action wishes for itself a supply of strength, contemplation desiderates that matters should be made clear: of these therefore the first is to be asked, the second is to be sought; so that the one may be given, the other found. But knowledge in this life belongs rather to the way than to the possession itself: but whoever has found the true way, will arrive at the possession itself which, however, is opened to him that knocks.

In order, therefore, that these three things— viz. asking, seeking, knocking— may be made clear, let us suppose, for example, the case of one weak in his limbs, who cannot walk: in the first place, he is to be healed and strengthened so as to be able to walk; and to this refers the expression He has used, Ask. But what advantage is it that he is now able to walk, or even run, if he should go astray by devious paths? A second thing therefore is, that he should find the road that leads to the place at which he wishes to arrive; and when he has kept that road, and arrived at the very place where he wishes to dwell, if he find it closed, it will be of no use either that he has been able to walk, or that he has walked and arrived, unless it be opened to him; to this, therefore, the expression refers which has been used, Knock.
[AD 430] Augustine of Hippo on Matthew 7:7-8
(ubi sup.) We must be careful therefore not to explain ought to him who does not receive it; for men the rather seek that which is hidden than that which is opened. He either attacks from ferocity as a dog, or overlooks from stupidity as swine. But it does not follow that if the truth be kept hid, falsehood is uttered. The Lord Himself who never spoke falsely, yet sometimes concealed the truth, as in that, I have yet many things to say unto you, the which ye are not now able to bear. (John 16:12.) But if any is unable to receive these things because of his filthiness, we must first cleanse him as far as lays in our power either by word or deed. But in that the Lord is found to have said some things which many who heard Him did not receive, but either rejected or contemned them, we are not to think that therein He gave the holy thing to the dogs, or cast His pearls before swine. He gave to those who were able to receive, and who were in the company, whom it was not fit should be neglected for the uncleanness of the rest. And though those who tempted Him might perish in those answers which He gave to them, yet those who could receive them by occasion of these inquiries heard many useful things. He therefore who knows what should be answered ought to make answer, for their sakes at least who might fall into despair should they think that the question proposed is one that cannot be answered. But this only in the case of such matters as pertain to instruction of salvation; of things superfluous or harmful nothing should be said; but it should then be explained for what reason we ought not to make answer in such points to the enquirer.

(ubi sup.) Otherwise; when He commanded not to give the holy thing to dogs, and not to cast pearls before swine, the hearer conscious of his own ignorance might say, Why do you thus bid me not give the holy thing to dogs, when as yet I see not that I have any holy thing? He therefore adds in good season, Ask, and ye shall receive.

(Serm. in Mont. ii. 21.) Asking, is that we may get healthiness of soul that we may be able to fulfil the things commanded us; seeking, pertains to the discovery of the truth. But when any has found the true way, he will then come into actual possession, which however is only opened to him that knocks.

(Retract. i. 19.) How these three differ from one another, I have thought good to unfold with this travail; but it were better to refer them all to instant prayer; wherefore He afterwards concludes, saving, He will give good things to them that ask him.

(Tract. in Joan. 44. 13.) Wherefore God hears sinners; for if He do not hear sinners, the Publican said in vain, Lord, be merciful to me a sinner; (Luke 18:13.) and by that confession merited justification.

(Prosper, Sent. 212.) He who in faith offers supplication to God for the necessities of this life is heard mercifully, and not heard mercifully. For the physician knows better than the sick man what is good for his sickness. But if he asks that which God both promises and commands, his prayer shall be granted, for love shall receive what truth provides.

(Ep. 31. 1.) But the Lord is good, who often gives us not what we would, that He may give us what we should rather prefer.

(Serm. in Mont. ii. 21.) There is need moreover of perseverance, that we may receive what we ask for.

(Serm. 61. 5.) In that God sometimes delays His gifts, He but recommends, and does not deny them. For that which is long looked for is sweeter when obtained; but that is held cheap, which comes at once. Ask then and seek things righteous. For by asking and seeking grows the appetite of taking. God reserves for you those things which He is not willing to give you at once, that you may learn greatly to desire great things. Therefore we ought always to pray and not to fail.

But when the precept was given that a holy thing should not be given to dogs and that pearls should not be cast before swine, questions abound. Mindful of our own ignorance and frailty and hearing it prescribed that we are not to give away something that we have not yet received, we might therefore ask, “What holy thing do you forbid me to give to dogs, and what pearls do you forbid me to cast before swine? For I do not see that I have as yet received them.” Most aptly, then, did the Lord go on to say, “Ask, and it shall be given you; seek and you shall find; knock, and it shall be opened to you. For everyone who asks, receives; and one who seeks, finds; and to one who knocks, it shall be opened.” The asking refers to obtaining soundness and strength of mind through prayer, in order that we may be able to fulfill the precepts that are being given. The seeking refers to finding truth. For the blessed life is made up of acting and knowing. Action requires a store of strength, while contemplation requires the manifestation of truths. Of these two, we are to ask for the first and we are to seek for the other in order that the one may be given and that the other may be found. In this life, however, knowledge consists in knowing the way toward that blessedness rather than in possessing it. But when anyone has found the true way, that one will arrive at that possession. As for you, it is to one who knocks that the door is opened. In order that these three things—the asking, the seeking and the knocking—may be illustrated by an example, let us consider the case of one who is unable to walk because of weak limbs. Of course, such a one must first be healed and strengthened for walking. Hence the Lord said, “Ask.”

Otherwise; Having given them some commands for the sanctification of prayer, saying, Judge not, He adds accordingly, Ask, and it shall be given unto you, as though He were to say, If ye observe this mercy towards your enemies, whatever seems to you shut, knock, and it shall be opened to you. Ask therefore in prayer, praying day and night; seek with care and toil; for neither by toiling only in the Scriptures do we gain knowledge without God's grace, nor do we attain to grace without study, lest the gift of God should be bestowed on the careless. But knock with prayer, and fasting, and alms. For as one who knocks at a door, not only cries out with his voice, but strikes with his hand, so he who does good works, knocks with his works. But you will say, this is what I pray that I may know and do, how then can I do it, before I receive? Do what you can that you may become able to do more, and keep what you know that you may come to know more. Or otherwise; having above commanded all men to love their enemies, and after enjoined that we should not under pretext of love give holy things to dogs; He here gives good counsel, that they should pray God for them, and it shall be granted them; let them seek out those that are lost in sins, and they shall find them; let them knock at those who are shut up in errors, and God shall open to them that their word may have access to their souls. Or otherwise; Since the precepts given above were beyond the reach of human virtue, He sends them to God to whose grace nothing is impossible, saying, Ask, and it shall be given you, that what cannot be performed by men may be fulfilled through the grace of God. For when God furnished the other animals with swift foot, or swift wing, with claws, teeth, or horns, He so made man that He Himself should be man's only1 strength, that forced by reason of his own weakness, he might always have need of his Lord.

He had said, Ask, and ye shall receive; which sinners hearing might perchance say, The Lord herein exhorts them that are worthy, but we are unworthy. Therefore He repeats it that He may commend the mercy of God to the righteous as well as to sinners; and therefore declares that every one that asketh receiveth; that is, whether he be righteous or a sinner, let him not hesitate to ask; that it may be fully seen that none is neglected but he who hesitates to ask of God. For it is not credible that God should enjoin on men that work of piety which is displayed in doing good to our enemies, and should not Himself (being good) act so.

Moreover, great hope has been given, and is given, by Him who does not deceive when He promises.
Hence there is need of perseverance, in order that we may receive what we ask, and find what we seek, and that what we knock at may be opened. Now, just as He talked of the fowls of heaven and of the lilies of the field, that we might not despair of food and clothing being provided for us, so that our hopes might rise from lesser things to greater; so also in this passage, Or what man is there of you, says He, whom if his son ask bread, will he give him a stone? Or if he ask a fish, will he give him a serpent? If you then, being evil, know how to give good gifts unto your children, how much more shall your Father which is in heaven give good things to them that ask Him? How do the evil give good things? Now, He has called those evil who are as yet the lovers of this world and sinners. And, in fact, the good things are to be called good according to their feeling, because they reckon these to be good things. Although in the nature of things also such things are good, but temporal, and pertaining to this feeble life: and whoever that is evil gives them, does not give of his own; for the earth is the Lord's, and the fullness thereof, who made heaven, and earth, the sea, and all that therein is. How much reason, therefore, there is for the hope that God will give us good things when we ask Him, and that we cannot be deceived, so that we should get one thing instead of another, when we ask Him; since we even, although we are evil, know how to give that for which we are asked? For we do not deceive our children; and whatever good things we give are not given of our own, but of what is His.
[AD 1107] Theophylact of Ohrid on Matthew 7:8
. In what has preceded the Lord has commanded us to do great and difficult things. Here He shows us how these things can be accomplished: through unceasing prayer. For He said, "Ask," that is, "keep asking," meaning, "ask continuously." For He did not say, "Ask one time." Then He affirms what He has said by an example from everyday life.
[AD 220] Tertullian on Matthew 7:9
And so, in petitioning for "daily bread," we ask for perpetuity in Christ, and indivisibility from His body. But, because that word is admissible in a carnal sense too, it cannot be so used without the religious remembrance withal of spiritual Discipline; for (the Lord) commands that bread be prayed for, which is the only food necessary for believers; for "all other things the nations seek after." The like lesson He both inculcates by examples, and repeatedly handles in parables, when He says, "Doth a father take away bread from his children, and hand it to dogs? " and again, "Doth a father give his son a stone when he asks for bread? " For He thus shows what it is that sons expect from their father. Nay, even that nocturnal knocker knocked for "bread." Moreover, He Justly added, "Give us this day," seeing He had previously said, "Take no careful thought about the morrow, what ye are to eat." To which subject He also adapted the parable of the man who pondered on an enlargement of his barns for his forthcoming fruits, and on seasons of prolonged security; but that very night he dies.

[AD 407] John Chrysostom on Matthew 7:9-11
There are two things behoveful for one that prays; that he ask earnestly; and that he ask such things as he ought to ask. And those are spiritual things; as Solomon, because he asked such things as were right, received speedily.

This He said not detracting from human nature, nor confessing the whole human race to be evil; but He calls paternal love evil when compared with His own goodness. Such is the superabundance of His love towards men.

[AD 407] John Chrysostom on Matthew 7:9
Because, as among men, if you keep on doing so, you are even accounted troublesome, and disgusting: so with God, when you do not so, then thou dost more entirely provoke Him. And if you continue asking, though thou receive not at once, thou surely wilt receive. For to this end was the door shut, that He may induce you to knock: to this end He does not straightway assent, that you may ask. Continue then to do these things, and you will surely receive. For that you might not say, What then if I should ask and not receive? He has blocked up your approach with that similitude, again framing arguments, and by those human things urging us to be confident on these matters; implying by them that we must not only ask, but ask what we ought.

For which of you is there, a father, of whom if his son shall ask bread, will he give him a stone? So that if you receive not, your asking a stone is the cause of your not receiving. For though thou be a son, this suffices not for your receiving: rather this very thing even hinders your receiving, that being a son, you ask what is not profitable.

Do thou also therefore ask nothing worldly, but all things spiritual, and you will surely receive. For so Solomon, because he asked what he ought, behold how quickly he received. Two things now, you see, should be in him that prays, asking earnestly, and asking what he ought: since you too, says He, though ye be fathers, wait for your sons to ask: and if they should ask of you anything inexpedient, you refuse the gifts; just as, if it be expedient, you consent and bestow it. Do thou too, considering these things, not withdraw until thou receive; until thou have found, retire not; relax not your diligence, until the door be opened. For if you approach with this mind, and say, Except I receive, I depart not; you will surely receive, provided thou ask such things, as are both suitable for Him of whom you ask to give, and expedient for you the petitioner. But what are these? To seek the things spiritual, all of them; to forgive them that have trespassed, and so to draw near asking forgiveness; to lift up holy hands without wrath and doubting. If we thus ask, we shall receive. As it is, surely our asking is a mockery, and the act of drunken rather than of sober men.

What then, says one, if I ask even spiritual things, and do not receive? You did not surely knock with earnestness; or you made yourself unworthy to receive; or quickly left off.

And wherefore, it may be inquired, did He not say, what things we ought to ask? Nay verily, He has mentioned them all in what precedes, and has signified for what things we ought to draw near. Say not then, I drew near, and did not receive. For in no case is it owing to God that we receive not, God who loves us so much as to surpass even fathers, to surpass them as far as goodness does this evil nature.
[AD 420] Jerome on Matthew 7:9-11
Or perhaps he called the Apostles evil, in their person condemning the whole human race, whose heart is set to evil from his infancy, as we read in Genesis. Nor is it any wonder that He should call this generation evil, (Gen. 8:22.) as the Apostle also speaks, Seeing the days are evil.

(Serm. 61. 5.) In that God sometimes delays His gifts, He but recommends, and does not deny them. For that which is long looked for is sweeter when obtained; but that is held cheap, which comes at once. Ask then and seek things righteous. For by asking and seeking grows the appetite of taking. God reserves for you those things which He is not willing to give you at once, that you may learn greatly to desire great things. Therefore we ought always to pray and not to fail.

(Serm. in Mont. ii. 21.) As above He had cited the birds of the air and the lilies of the field, that our hopes may rise from the less to the greater; so also does He in this place, when He says, Or what man among you?

(ubi sup.) Or; He calls evil (Eph. 5:16.) those who are lovers of this age; whence also the good things which they give are to be called good according to their sense who esteem them as good; nay, even in the nature of things they are goods, that is, temporal goods, and such as pertain to this weak life.

(Serm. 61, 3.) For that good thing which makes men good is God. Gold and silver are good things not as making you good, but as with them you may do good. If then we be evil, yet as having a Father who is good let us not remain ever evil.

(Serm. in Mont. ii. 21.) If then we being evil, know how to give that which is asked of us, how much more is it to be hoped that God will give us good things when we ask Him?

But how do evil people give good gifts? Those whom he here calls evil are sinners. As such they are still lovers of this world. It is in accordance with their notion of good that their gifts are to be called good. Their gifts are called good, that is, because the givers consider them good. Although these things are good in the order of nature, they are nevertheless temporal things pertaining to the infirmities of life. Moreover, whenever an evil person bestows them, he is not giving what is his own, for “the earth and the fullness thereof is the Lord’s.… Who made heaven and earth, the sea, and all things that are in them.” So even we who are evil know how to give what is asked. How much more confidence ought we to have that God will give us good things when we ask. God will not deceive us by giving us one thing rather than another when we ask of him. Even we do not deceive our children. And whatever good gifts we bestow, we give what is God’s and not our own.

By the fish we may understand the word concerning Christ, by the serpent the Devil himself. Or by the loaf may be understood spiritual doctrine; by the stone ignorance; by the fish the water of Holy Baptism; by the serpent the wiles of the Devil, or unbelief.

The sense therefore is; we need not fear that should we ask of God our Father bread, that is doctrine or love, He will give us a stone; that is, that He will suffer our heart to be contracted either by the frost of hatred or by hardness of soul; or that when we ask for faith, He will suffer us to die of the poison of unbelief. Thence it follows, If then ye being evil.

And be it known that where Matthew says, He shall give good things, Luke has, shall give his Holy Spirit. (Luke 11:13.) But this ought not to seem contrary, because all the good things which man receives from God, are given by the grace of the Holy Spirit.

Or; bread which is the common food signifies charity, without which the other virtues are of no avail. The fish signifies faith, which is born of the water of baptism, is tossed in the midst of the waves of this life and yet lives. Luke adds a third thing, an egg, (Luke 11:12.) which signifies hope; for an egg is the hope of the animal. To charity, He opposes a stone, that is, the hardness of hatred; to faith, a serpent, that is, the venom of treachery; to hope, a scorpion, that is, despair, which stings backward, as the scorpion.

And what are the things that we ought to ask, he shows under the likeness of a loaf, and a fish. The loaf is the word concerning the knowledge of God the Father. The stone is all falsehood that has a stumbling-block of offence to the soul.

Because in comparison of God who is preeminently good, all men seem to be evil, as all light shows dark when compared with the sun.

[AD 407] John Chrysostom on Matthew 7:11
Now this He said, not to bring an evil name on man's nature, nor to condemn our race as bad; but in contrast to His own goodness He calls paternal tenderness evil, so great is the excess of His love to man.

Do you see an argument unspeakable, of power to arouse to good hopes even him that has become utterly desperate?

Now here indeed He signifies His goodness by means of our fathers, but in what precedes by the chief among His gifts, by the soul, by the body. And nowhere does He set down the chief of all good things, nor bring forward His own coming:— for He who thus made speed to give up His Son to the slaughter, how shall He not freely give us all things?— because it had not yet come to pass. But Paul indeed sets it forth, thus saying, He that spared not His own Son, how shall He not also with Him freely give us all things. Romans 8:32 But His discourse with them is still from the things of men.

6. After this, to indicate that we ought neither to feel confidence in prayer, while neglecting our own doings; nor, when taking pains, trust only to our own endeavors; but both to seek after the help from above, and contribute withal our own part; He sets forth the one in connection with the other. For so after much exhortation, He taught also how to pray, and when He had taught how to pray, He proceeded again to His exhortation concerning what we are to do; then from that again to the necessity of praying continually, saying, Ask, and seek, and knock. And thence again, to the necessity of being also diligent ourselves.
[AD 420] Jerome on Matthew 7:11-12
(Ver. 11, 12.) So if you, being evil, know how to give good things to your children, how much more will your Father who is in heaven give good things to those who ask Him! Therefore, whatever you want men to do to you, do also to them, for this is the Law and the Prophets. It should be noted that when he referred to the apostles as evil, unless perhaps under the guise of the apostles the entire race of men is condemned, whose hearts are inclined to evil from infancy in comparison to divine mercy. Read Genesis (Genesis 8). It is not surprising if people of this age are called evil, since even the apostle Paul recalls: Redeeming the time, for the days are evil (Ephesians 5:16).

He says not, All things whatsoever, simply, but All things therefore, as though He should say, If ye will be heard, besides those things which I have now said to you, do this also. And He said not, Whatsoever you would have done for you by God, do that for your neighbour; lest you should say, But how can I? but He says, Whatsoever you would have done to you by your fellow-servant, do that also to your neighbour.

Summing up all in brief, and signifying, that virtue is compendious, and easy, and readily known of all men.

And He did not merely say, All things whatsoever ye would, but, Therefore all things whatsoever ye would. For this word, therefore, He did not add without purpose, but with a concealed meaning: if you desire, says He, to be heard, together with what I have said, do these things also. What then are these? Whatsoever ye would that men should do to you. Do you see how He has hereby also signified that together with prayer we need exact conversation? And He did not say, whatsoever things you would to be done unto you of God, those do unto your neighbor; lest you should say, But how is it possible? He is God and I am man: but, whatsoever you would to be done unto you of your fellow servant, these things do thou also yourself show forth towards your neighbor. What is less burdensome than this? What fairer?

Then the praise also, before the rewards, is exceeding great.

For this is the law and the prophets. Whence it is evident, that virtue is according to our nature; that we all, of ourselves, know our duties; and that it is not possible for us ever to find refuge in ignorance.
[AD 407] John Chrysostom on Matthew 7:12
In this statement Jesus briefly sums up all that is required. He shows that the definition of virtue is short and easy and known already to all. And he did not merely say, “Whatever things that you want,” but “Therefore whatever things that you want.” For he did not add this word therefore in its straightforward sense, but rather he used it with a deeper meaning. He is saying, “If you want to be heard, do these things in addition to those about which I have already spoken.” What are these additional things? “Whatever are those things that you want people to do to you.” Do you see how this shows that our wishes imply careful regulation of our behavior? Note that he did not say, “Whatever things that you want God to do for you, do these things to your neighbor.” Thus you cannot say, “How is that even possible? He is God and I am a human being!” Instead, Jesus said, “Whatever things that you want your fellow servant to do, you yourself also perform for your neighbor.” What is less of a burden than this? What is more just? Then the praise is exceedingly great: “For this is the law and the prophets.” From this it is clear that virtue is defined in accordance with our nature. So we all know within ourselves what our duties are. We cannot ever again find refuge in ignorance.

[AD 430] Augustine of Hippo on Matthew 7:12
(ubi sup.) Firmness and strength of walking by the way of wisdom in good habits is thus set before us, by which men are brought to purity and simplicity of heart; concerning which having spoken a long time, He thus concludes, All things whatsoever ye would, &c. For there is no man who would that another should act towards him with a double heart.

(Serm. 61. 7.) Otherwise; The Lord had promised that He would give good things to them that ask Him. But that He may own his petitioners, let us also own ours. For they that beg are in every thing, save having of substance, equal to those of whom they beg. What face can you have of making request to your God, when you do not acknowledge your equal? This is that is said in Proverbs, Whoso stoppeth his ear to the cry of the poor, he shall cry and shall not be heard. (Prov. 21:13.) What we ought to bestow on our neighbour when he asks of us, that we ourselves may be heard of God, we may judge by what we would have others bestow upon us; therefore He says, All things whatsoever ye would.

(Serm. in Mont. ii. 22.) Some Latin copies add here, good thingsb, which I suppose was inserted to make the sense more plain. For it occurred that one might desire some crime to be committed for his advantage, and should so construe this place, that he ought first to do the like to him by whom he would have it done to him. It were absurd to think that this man had fulfilled this command. Yet the thought is perfect, even though this be not added. For the words, All things whatsoever ye would, are not to be taken in their ordinary and loose signification, but in their exact and proper sense. For there is no will but only in the good; (but vid. Retract. i. 9. n. 4.) in the wicked it is rather named desire, and not will. Not that the Scriptures always observe this propriety; but where need is, there they retain the proper word so that none other need be understood.

(Serm. in Mont. ii. 22.) This precept seems to refer to the love of our neighbour, not of God, as in another place He says, there are two commandments on which hang the Law and the Prophets. But as He says not here, The whole Law, as He speaks there, He reserves a place for the other commandment respecting the love of God.

(De Trin. viii. 7.) Otherwise; Scripture does not mention the love of God, where it says, All things whatsoever ye would; because he who loves his neighbour must consequently love Love itself above all things; but God is Love; therefore he loves God above all things.

Source: Catena Aurea by Aquinas
[AD 430] Augustine of Hippo on Matthew 7:12
Moreover, a certain strength and vigour in walking along the path of wisdom ties in good morals, which are made to extend as far as to purification and singleness of heart—a subject on which He has now been speaking long, and thus concludes: Therefore all good things whatsoever ye would that men should do to you, do ye even so to them: for this is the law and the prophets. In the Greek copies we find the passage runs thus: Therefore all things whatsoever ye would that men should do to you, do ye even so to them. But I think the word good has been added by the Latins to make the sentence clear. For the thought occurred, that if any one should wish something wicked to be done to him, and should refer this clause to that—as, for instance, if one should wish to be challenged to drink immoderately, and to get drunk over his cups, and should first do this to the party by whom he wishes it to be done to himself—it would be ridiculous to imagine that he had fulfilled this clause. Inasmuch, therefore, as they were influenced by this consideration, as I suppose, one word was added to make the matter clear; so that in the statement, Therefore all things whatsoever ye would that men should do to you, there was inserted the word good. But if this is wanting in the Greek copies, they also ought to be corrected: but who would venture to do this? It is to be understood, therefore, that the clause is complete and altogether perfect, even if this word be not added. For the expression used, whatsoever ye would, ought to be understood as used not in a customary and random, but in a strict sense. For there is no will except in the good: for in the case of bad and wicked deeds, desire is strictly spoken of, not will. Not that the Scriptures always speak in a strict sense; but where it is necessary, they so keep a word to its perfectly strict meaning, that they do not allow anything else to be understood.

Moreover, this precept seems to refer to the love of our neighbour, and not to the love of God also, seeing that in another passage He says that there are two precepts on which hang all the law and the prophets. For if He had said, All things whatsoever ye would should be done to you, do ye even so; in this one sentence He would have embraced both those precepts: for it would soon be said that every one wishes that he himself should be loved both by God and by men; and so, when this precept was given to him, that what he wished done to himself he should himself do, that certainly would be equivalent to the precept that he should love God and men. But when it is said more expressly of men, Therefore all things whatsoever ye would that men should do to you, do ye even so to them, nothing else seems to be meant than, You shall love your neighbour as yourself. But we must carefully attend to what He has added here: for this is the law and the prophets. Now, in the case of these two precepts, He not merely says, The law and the prophets hang; but He has also added, all the law and the prophets, which is the same as the whole of prophecy: and in not making the same addition here, He has kept a place for the other precept, which refers to the love of God. Here, then, inasmuch as He is following out the precepts with respect to a single heart, and it is to be dreaded lest any one should have a double heart toward those from whom the heart can be hid, i.e. toward men, a precept with respect to that very thing was to be given. For there is almost nobody that would wish that any one of double heart should have dealings with himself. But no one can bestow anything upon a fellowman with a single heart, unless he so bestow it that he expects no temporal advantage from him, and does it with the intention which we have sufficiently discussed above, when we were speaking of the single eye.

The eye, therefore, being cleansed and rendered single, will be adapted and suited to behold and contemplate its own inner light. For the eye in question is the eye of the heart. Now, such an eye is possessed by him who, in order that his works may be truly good, does not make it the aim of his good works that he should please men; but even if it should turn out that he pleases them, he makes this tend rather to their salvation and to the glory of God, not to his own empty boasting; nor does he do anything that is good tending to his neighbour's salvation for the purpose of gaining by it those things that are necessary for getting through this present life; nor does he rashly condemn a man's intention and wish in that action in which it is not apparent with what intention and wish it has been done; and whatever kindnesses he shows to a man, he shows them with the same intention with which he wishes them shown to himself, viz. as not expecting any temporal advantage from him: thus will the heart be single and pure in which God is sought. Blessed, therefore, are the pure in heart: for they shall see God.
[AD 430] Augustine of Hippo on Matthew 7:12
Elsewhere Jesus says that there are two precepts on which the whole law and the prophets depend. The present precept seems to concern only the love of neighbor and not the love of God as well. Of course, if he had said, “All things whatever you wish to have done to you, do you also those things,” he would then have embraced those two precepts in the one maxim, for it would be readily understood that everyone would wish to be loved by both God and other persons. So, when someone would be given that one precept—when he would be required to do whatever he would wish to have done to him—then he would of course implicitly be given the other precept as well: that he should love both God and neighbor. But it would seem that the present maxim means nothing more than “You shall love your neighbor as yourself,” for it seems very expressly restricted to persons, since it reads, “Whatever you wish that people would do to you, do so to them.” However, we must pay close attention to his further observation on this point, for Jesus goes on to say, “This is the law and the prophets.” In the case of the previously mentioned two precepts, he did not say merely that “the law and the prophets depend on them.” He said that “the whole law and the prophets depend” on them, for that is the sum of prophecy. But by omitting the word whole in the present instance, he seems to reserve a place for the other precept—the precept that pertains to the love of God. At any rate, the present instruction is one that was most apt for the occasion when he was expounding the precepts that pertain to singleness of heart. For there might be reason to fear that a person may have a double heart toward another, since the matters of the heart are hidden. But there is hardly anyone who would wish that others would deal double-heartedly with oneself. It is impossible for one to render service single-heartedly to another unless one renders it in such a way that one looks for no temporal advantage from it. And one cannot do this unless one is motivated by the kind of intention that we have sufficiently discussed earlier, when we were speaking about the eye that is single.

[AD 407] John Chrysostom on Matthew 7:13-14
But seeing He declares below, My yoke is pleasant, and my burden light, how is it that He says here that the way is strait and narrow? Even here He teaches that it is light and pleasant; for here is a way and a gate as that other, which is called the wide and broad, has also a way and a gate. Of these nothing is to remain; but all pass away. But to pass through toil and sweat, and to arrive at a good end, namely life, is sufficient solace to those who undergo these struggles. For if sailors can make light of storms and soldiers of wounds in hope of perishable rewards, much more when Heaven lies before, and rewards immortal, will none look to the impending dangers. Moreover the very circumstance that He calls it strait contributes to make it easy; by this He warned them to be always watching; this the Lord speaks to rouse our desires. He who strives in a combat, if he sees the prince admiring the efforts of the combatants, gets greater heart. Let us not therefore be sad when many sorrows befal us here, for the way is strait, but not the city; therefore neither need we look for rest here, nor expect any thing of sorrow there. When He says, Few there be that find it, He points to the sluggishness of the many, and instructs His hearers not to look to the prosperity of the many, but to the toils of the few.

[AD 407] John Chrysostom on Matthew 7:13-14
Remember that later Jesus would say, “My yoke is easy, and my burden is light.” And here he implies the same thing. Does it not seem inconsistent then to say here that the good road is narrow and constricted? Pay attention. He has made it clear the burden is very light, easy and agreeable. “But how,” one may say, “is the narrow and constricted road easy?” Because it is both a gate and a road. The other road is, of course, both a gate and a road, but on that way there is nothing that is enduring. All things on that way are temporary, both things pleasant and painful.

[AD 407] John Chrysostom on Matthew 7:13-14
It is not only on the way that the things of excellence become easy. In the end they become even more agreeable. For it is not just the passing away of toil and sweating but also the anticipated arrival at a pleasant destination that is sufficient to encourage the traveler. For this road ends in life! The result is that both the temporary nature of the toils and the eternal nature of the victor’s crowns, combined with the fact that these toils come first and the victor’s crowns come afterward, become a hearty encouragement.

[AD 407] John Chrysostom on Matthew 7:13
And yet after this He said, My yoke is easy, and my burden is light. Matthew 11:30 And in what He has lately said also, He intimated the same: how then does He here say it is strait and confined? In the first place, if you attend, even here He points to it as very light, and easy, and accessible. And how, it may be said, is the narrow and confined way easy? Because it is a way and a gate; even as also the other, though it be wide, though spacious, is also a way and a gate. And of these there is nothing permanent, but all things are passing away, both the pains and the good things of life.

And not only herein is the part of virtue easy, but also by the end again it becomes yet easier. For not the passing away of our labors and toils, but also their issuing in a good end (for they end in life) is enough to console those in conflict. So that both the temporary nature of our labors, and the perpetuity of our crowns, and the fact that the labors come first, and the crowns after, must prove a very great relief in our toils. Wherefore Paul also called their affliction light; not from the nature of the events, but because of the mind of the combatants, and the hope of the future. For our light affliction, says he, works an eternal weight of glory, while we look not at the things which are seen, but at the things which are not seen. 2 Corinthians 4:17-18 For if to sailors the waves and the seas, to soldiers their slaughters and wounds, to husbandmen the winters and the frosts, to boxers the sharp blows, be light and tolerable things, all of them, for the hope of those rewards which are temporary and perishing; much more when heaven is set forth, and the unspeakable blessings, and the eternal rewards, will no one feel any of the present hardships. Or if any account it, even thus, to be toilsome, the suspicion comes of nothing but their own remissness.

See, at any rate, how He on another side also makes it easy, commanding not to hold intercourse with the dogs, nor to give one's self over to the swine, and to beware of the false prophets; thus on all accounts causing men to feel as if in real conflict. And the very fact too of calling it narrow contributed very greatly towards making it easy; for it wrought on them to be vigilant. As Paul then, when he says, We wrestle not against flesh and blood, does so not to cast down, but to rouse up the spirits of the soldiers: even so He also, to shake the travellers out of their sleep, called the way rough. And not in this way only did He work upon men, to be vigilant, but also by adding, that it contains likewise many to supplant them; and, what is yet more grievous, they do not even attack openly, but hiding themselves; for such is the race of the false prophets. But look not to this, says He, that it is rough and narrow, but where it ends; nor that the opposite is wide and spacious, but where it issues.

And all these things He says, thoroughly to awaken our alacrity; even as elsewhere also He said, Violent men take it by force. For whoever is in conflict, when he actually sees the judge of the lists marvelling at the painfulness of his efforts, is the more inspirited.

Let it not then bewilder us, when many things spring up hence, that turn to our vexation. For the way is strait, and the gate narrow, but not the city. Therefore must one neither look for rest here, nor there expect any more anything that is painful.

Now in saying, Few there be that find it, here again He both declared the careless ness of the generality, and instructed His hearers not to regard the felicities of the many, but the labors of the few. For the more part, says He, so far from walking this way, do not so much as make it their choice: a thing of most extreme criminality. But we should not regard the many, nor be troubled thereat, but emulate the few; and, by all means equipping ourselves, should so walk therein.
[AD 420] Jerome on Matthew 7:13-14
Attend to the words, for they have an especial force, many walk in the broad way—few find the narrow way. For the broad way needs no search, and is not found, but presents itself readily; it is the way of all who go astray.

Many, after they have found the way of truth, caught by the pleasures of the world, desert midway.

How narrow is the gate and confined is the way that leads to life! And few are those who find it. The wide path is the pleasure of the world, which people desire. The narrow path, which is opened through struggles and fasting, which even the Apostle entered (II Cor. VI, XI): and Timothy is encouraged to enter through it (I Tim. V). At the same time, consider how clearly he has spoken about each path. Many walk the broad path, but few find the narrow one. The broad path is not sought after, nor is there a need for discovery: it offers itself willingly, and is the path of those who wander. But the narrow path, not everyone finds it, and those who do find it, do not immediately enter it. Indeed, many, once they have found the path of truth, are captivated by the pleasures of the world and turn back from the middle of the journey.

He says this not because the Lord’s yoke is rough or his burden heavy but because there are a few who wish their labors to end. They do not put their full trust in the Lord when he cries, “Come to me, all you who labor, and I will give you rest. Take my yoke upon you, and learn from me, for I am meek and humble of heart.… For my yoke is easy, and my burden light.” Hence the humble and the meek of heart are named at the very beginning of this sermon. But because there are many who spurn this smooth yoke and this light burden, it comes to pass that the way that leads to life is demanding and the entry gate is narrow.

But because this belongs to few, He now begins to speak of searching for and possessing wisdom, which is a tree of life; and certainly, in searching for and possessing, i.e. contemplating this wisdom, such an eye is led through all that precedes to a point where there may now be seen the narrow way and the strait gate. When, therefore, He says in continuation, Enter ye in at the strait gate: for wide is the gate, and broad is the way, that leads to destruction, and many there be which go in thereat: because strait is the gate, and narrow is the way, which leads unto life, and few there be that find it; He does not say so for this reason, that the Lord's yoke is rough, or His burden heavy; but because few are willing to bring their labours to an end, giving too little credit to Him who cries, Come unto me, all you that labour, and I will give you rest. Take my yoke upon you, and learn of me; for I am meek and lowly in heart: for my yoke is easy, and my burden is light (hence, moreover, the sermon before us took as its starting-point the lowly and meek in heart): and this easy yoke and light burden which many spurn, few submit to; and on that account the way becomes narrow which leads unto life, and the gate strait by which it is entered.
[AD 500] Desert Fathers on Matthew 7:13-14
A hermit was asked, ‘What is meant by the text “Narrow and strait is the way” (Matt. 7:14)?’ He answered, ‘Narrow and strait is the way by which a man does violence to his thoughts and for God’s sake breaks down his self-will. This is what was written about the apostles, “Lo, we have left all, and followed thee” (Matt. 19:27).’

. The narrow gate means both trials that are voluntarily undertaken, such as fasting and the like, and trials that are involuntarily experienced, such as imprisonment and persecution. Just as a man who is fat, or who is carrying a great load, cannot go in through a narrow gate, neither can a gourmandizer or a rich man. These go in through the wide gate. To show that narrowness is temporary and that width is likewise transitory, He calls them a "gate" and a "way." For the gate is hardship, and he who undergoes hardship passes through his hardship as quickly as he would pass through a gate. And the pleasures of the gourmandizer’s feast are as transitory as any moment in a journey along a road. Since both are temporary, we ought to choose the better of the two.
[AD 1274] Pseudo-Chrysostom on Matthew 7:13-14
Otherwise; This third precept again is connected with the right method of fasting, and the order of discourse will be this; But thou when thou fastest anoint thy head; and after comes, Enter ye in at the strait gate. For there are three chief passions in our nature, that are most adhering to the flesh; the desire of food and drink; the love of the man towards the woman; and thirdly, sleep. These it is harder to cut off from the fleshly nature than the other passions. And therefore abstinence from no other passion so sanctifies the body as that a man should be chaste, abstinent, and continuing in watchings. On account therefore of all these righteousnesses, but above all on account of the most toilsome fasting, it is that He says, Enter ye in at the strait gate. The gate of perdition is the Devil, through whom we enter into hell; the gate of life is Christ, through whom we enter into the kingdom of Heaven. The Devil is said to be a wide gate, not extended by the mightiness of his power, but made broad by the license of his unbridled pride. Christ is said to be a strait gate not with respect to smallness of power, but to His humility; for He whom the whole world contains not, shut Himself within the limits of the Virgin's womb. The way of perdition is sin of any kind It is said to be broad, because it is not contained within the rule of any discipline, but they that walk therein follow whatever pleases them. The way of life is all righteousness, and is called narrow for the contrary reasons. It must be considered that unless one walk in the way, he cannot arrive at the gate; so they that walk not in the way of righteousness, it is impossible that they should truly know Christ. Likewise neither does he run into the hands of the Devil, unless he walks in the way of sinners.

The fact that there are such men confessing themselves to be Christians, and admitting the crucified Jesus to be both Lord and Christ, yet not teaching His doctrines, but those of the spirits of error, causes us who are disciples of the true and pure doctrine of Jesus Christ, to be more faithful and steadfast in the hope announced by Him. For what things He predicted would take place in His name, these we do see being actually accomplished in our sight. For he said, 'Many shall come in My name, clothed outwardly in sheep's clothing, but inwardly they are ravening wolves.' [Matthew 7:15] And, 'There shall be schisms and heresies.' [1 Corinthians 11:19] And, 'Beware of false prophets, who shall come to you clothed outwardly in sheep's clothing, but inwardly they are ravening wolves.' [Matthew 7:15] And, 'Many false Christs and false apostles shall arise, and shall deceive many of the faithful.' [Matthew 24:11] There are, therefore, and there were many, my friends, who, coming forward in the name of Jesus, taught both to speak and act impious and blasphemous things; and these are called by us after the name of the men from whom each doctrine and opinion had its origin.

The Lord teaches us that many "ravening wolves shall come in sheep's clothing." Now, what are these sheep's clothing's, but the external surface of the Christian profession? Who are the ravening wolves but those deceitful senses and spirits which are lurking within to waste the flock of Christ? Who are the false prophets but deceptive predictors of the future? Who are the false apostles but the preachers of a spurious gospel? Who also are the Antichrists, both now and evermore, but the men who rebel against Christ? Heresies, at the present time, will no less rend the church by their perversion of doctrine, than will Antichrist persecute her at that day by the cruelty of his attacks, except that persecution make seven martyrs, (but) heresy only apostates.

Behold together with the dogs and swine another kind of ambush and conspiracy, far more grievous than that. For those are acknowledged and open, but these shaded over. For which cause also, while from those He commanded to hold off, these He charged men to watch with exact care, as though it were not possible to see them at the first approach. Wherefore He also said, beware; making us more exact to discern them.

Then, lest when they had heard that it was narrow and strait, and that they must walk on a way opposite to the many, and must keep themselves from swine and dogs, and together with these from another more wicked kind, even this of wolves; lest, I say, they should sink down at this multitude of vexations, having both to go a way contrary to most men, and therewith again to have such anxiety about these things: He reminded them of what took place in the days of their fathers, by using the term, false prophets, for then also no less did such things happen. Be not now, I pray you, troubled (so He speaks), for nothing new nor strange is to befall you. Since for all truth the devil is always secretly substituting its appropriate deceit.
[AD 407] John Chrysostom on Matthew 7:15
Jesus reminded them of what happened to their ancestors who were attracted to false prophets. The same dangers are now faced as those that occurred in earlier days. He reminded them of the experience of their ancestors so that they would not despair at the multitude of troubles that would mount up on this way that is narrow and constricted. He reminded them that it is necessary to walk in a way that goes contrary to the common opinion. One must guard oneself not only against pigs and dogs but those other, more elusive creatures: the wolves. They were going to face inward anxieties as well as outward difficulties, but they are not to despair. “Therefore do not be thrown into confusion,” Jesus says in effect, “for nothing will happen that is new or strange. Remember that the ancient adversary is forever introducing deception as if true.”

Notice that along with the dogs and pigs there is another form of ambush and plotting that causes far more trouble than that of dogs or pigs. For the dogs and pigs do not hide their nature. They are obvious. But the movements of wolves are hidden in shadows. Hence he commanded that one should not only avoid the dogs and pigs but also that one should continuously and carefully look out for wolves, because one cannot see them the moment they attack. For this reason he says, “Watch out!”—to make his hearers more careful to distinguish deception from truth.

Having taught that the gate is strait, because there are many that pervert the way that leads to it, He proceeds, Take heed of false prophets. In the which that they might be the more careful, He reminds them of the things that were done among their fathers, calling them false prophets; for even in that day the like things fell out.

Yet He may seem here to have aimed under the title of false prophets, not so much at the heretic, as at those who, while their life is corrupt, yet wear an outward face of virtuousness; whence it is said, By their fruits ye shall know them. For among heretics it is possible many times to find a good life, but among those I have named never.

And a hypocrite is easily discerned; for the way they are commanded to walk is a hard way, and the hypocrite is loth to toil. And that you may not say that you are unable to find out them that are such, He again enforces what He had said by example from men, saying, Do men gather grapes of thorns, or figs of thistles?

But that none should say, An evil tree brings forth indeed evil fruit, but it brings forth also good, and so it becomes hard to discern, as it has a two-fold produce; on this account He adds, A good tree cannot bring forth evil fruit, neither can an evil tree bring forth good fruit.

He had not enjoined them to punish the false prophets, and therefore shows them the terrors of that punishment that is of God, saying, Every tree that bringeth not forth good fruit shall be hewn down, and cast into the fire. In these words He seems to aim also at the Jews, and thus calls to mind the word of John the Baptist, denouncing punishment against them in the very same words. For he had thus spoken to the Jews, warning them of the axe impending, the tree that should be cut down, and the fire that could not be extinguished. But if one will examine somewhat closely, here are two punishments, to be cut down, and to be burned; and he that is burned is also altogether cut out of the kingdom; which is the harder punishment. Many indeed fear no more than hell; but I say that the fall of that glory is a far more bitter punishment, than the pains of hell itself. For what evil great or small would not a father undergo, that he might see and enjoy a most dear son? Let us then think the same of that glory; for there is no son so dear to his father as is the rest of the good, to be deceased and to be with Christ. The pain of hell is indeed intolerable, yet are ten thousand hells nothing to falling from that blessed glory, and being held in hate by Christ.

What is here spoken of false prophets we may apply to all whose dress and speech promise one thing, and their actions exhibit another. But it is specially to be understood of heretics, who by observing temperance, chastity, and fasting, surround themselves as it were with a garment of sanctity, but inasmuch as their hearts within them are poisoned, they deceive the souls of the more simple brethren.

We would ask those heretics who affirm that there are two natures directly opposed to each other, if they admit that a good tree cannot bring forth evil fruit, how it was possible for Moses, a good tree, to sin as he did at the water of contradiction? Or for Peter to deny his Lord in the Passion, saying, I know not the man? Or how, on the other hand, could Moses' father-in-law, an evil tree, inasmuch as he believed not in the God of Israel, give good counsel?

It is possible to understand all things, as those who promise one thing in appearance and speech but show another thing in action. But especially, this should be understood about heretics, who seem to clothe themselves in the appearance of piety through continence, chastity, and fasting, but inwardly they have a poisoned heart and deceive the minds of the simple brothers. Therefore, from the fruits of the soul, which drag innocence to ruin, they are compared to ravenous wolves.

Here, therefore, those who promise a wisdom and a knowledge of the truth which they do not possess, are especially to be guarded against; as, for instance, heretics, who frequently commend themselves on account of their fewness. And hence, when He had said that there are few who find the strait gate and the narrow way, lest they [the heretics] should falsely substitute themselves under the pretext of their fewness.
[AD 430] Augustine of Hippo on Matthew 7:15-20
(Serm. in Mont. ii. 23.) When the Lord had said that there were few that find the strait gate and narrow way, that heretics, who often commend themselves because of the smallness of their numbers, might not here intrude themselves, He straightway subjoins, Take heed of false prophets.

(Serm. in Mont. ii. 24.) Wherefore it is justly asked, what fruits then He would have us look to? For many esteem among fruits some things which pertain to the sheep's clothing, and in this manner are deceived concerning wolves. For they practise fasting, almsgiving, or praying, which they display before men, seeking to please those to whom these things seem difficult. These then are not the fruits by which He teaches us to discern them. Those deeds which are done with good intention, are the proper fleece of the sheep itself, such as are done with bad intention, or in error, are nothing else than a clothing of wolves; but the sheep ought not to hate their own clothing because it is often used to hide wolves. What then are the fruits by which we may know an evil tree? The Apostle says, The works of the flesh are manifest, which are, fornication, uncleanness, &c. (Gal. 5:19.) And which are they by which we may know a good tree? The same Apostle teaches, saying, The fruits of the Spirit are love, joy, peace.

(non occ.) But from their actions we may conjecture whether this their outward appearance is put on for display. For when by any temptations those things are withdrawn or denied them which they had either attained or sought to attain by this evil, then needs must that it appear whether they be the wolf in sheep's clothing, or the sheep in his own.

(Serm. in Mont. ii. 25.) In this place we must guard against the error of such as imagine that the two trees refer to two different natures; the one of God, the other not. But we affirm that they derive no countenance from these two trees; (Manichees, vid. infr.) as it will be evident to any who will read the context that He is speaking here of men.

(De Civ. Dei, 12. 4.) These men of whom we have spoken are offended with these two natures, not considering them according to their true usefulness; whereas it is not by our advantage or disadvantage, but in itself considered, that nature gives glory to her Framer. All natures then that are, because they are, have their own manner, their own appearance, and as it were their own1 harmony, and are altogether good.

(Serm. in Mont. ii. 25.) From this speech the Manichees suppose that neither can a soul that is evil be possibly changed for better, nor one that is good into worse. As though it had been, A good tree cannot become bad, nor a bad tree become good; whereas it is thus said, A good tree cannot bring forth evil fruit, nor the reverse. The tree is the soul, that is, the man himself; the fruit is the man's works. An evil man therefore cannot work good works, nor a good man evil works. Therefore if an evil man would work good things, let him first become good. But as long as he continues evil, he cannot bring forth good fruits. Like as it is indeed possible that what was once snow, should cease to be so; but it cannot be that snow should be warm; so it is possible that he who has been evil should be so no longer; but it is impossible that an evil man should do good. For though he may sometimes be useful, it is not he that does it, but it comes of Divine Providence superintending.

(vid. Op. Imp. in. Jul. v. 40. &c. et alibi.) But as it is manifest that all evil works proceed from an evil will, as its fruits from an evil tree; so of this evil will itself whence will you say that it has sprung, except that the evil will of an angel sprung from an angel, of man from man? And what were these two before those evils arose in them, but the good work of God, a good and praiseworthy nature. See then out of good arises evil; nor was there any thing at all out of which it might arise but what was good. I mean the evil will itself, since there was no evil before it, no evil works, which could not come but from evil will as fruit from an evil tree. Nor can it be said that it sprung out of good in this way, because it was made good by a good God; for it was made of nothing, and not of God.

The Lord had before commanded His Apostles, that they should not do their alms, prayers, and fastings before men, as the hypocrites; and that they might know that all these things may be done in hypocrisy, He speaks saying, Take heed of false prophets.

What is written below that the Law and the Prophets were until John, (Mat. 11:13.) is said, because there should be no prophecy concerning Christ after He was come. Prophets indeed there have been and are, but not prophesying of Christ, rather interpreting the things which had been prophesied of Christ by the ancients, that is by the doctors of the Churches. For no man can unfold prophetic meaning, but the Spirit of prophecy. The Lord then knowing that there should be false teachers, warns them of divers heresies, saying, Take heed of false prophets. And forasmuch as they would not be manifest Gentiles, but lurk under the Christian name, He said not 'See ye,' but, Take heed. For a thing that is certain is simply seen, or looked upon; but when it is uncertain it is watched or narrowly considered. Also He says Take heed, because it is a sure precaution of security to know him whom you avoid. But this form of warning, Take heed, does not imply that the Devil will introduce heresies against God's will, but by His permission only; but because He would not choose servants without trial, therefore He sends them temptation; and because He would not have them perish through ignorance, He therefore warns them beforehand. Also that no heretical teacher might maintain that He spoke here of Gentile and Jewish teachers and not of them, He adds, who come to yon in sheep's clothing. Christians are called sheep, and the sheep's clothing is a form of Christianity and of feigned religion. And nothing so casts out all good as hypocrisy; for evil that puts on the semblance of good, cannot be provided against, because it is unknown. Again, that the heretic might not allege that He here speaks of the true teachers which were yet sinners, He adds, But inwardly they are ravening wolves. But Catholic teachers should they indeed have been sinners, are spoken of as servants of the flesh, yet not as ravening wolves, because it is not their purpose to destroy Christians. Clearly then it is of heretical teachers that He speaks; for they put on the guise of Christians, to the end they may tear in pieces the Christian with the wicked fangs of seduction. Concerning, such the Apostle speaks, I know that after my departure there will enter among you grievous wolves, not sparing the flock. (Acts 20:29.)

The fruits of a man are the confession of his faith and the works of his life; for he who utters according to God the words of humility and a true confession, is the sheep; but he who against the truth howls forth blasphemies against God, is the wolf.

The grape has in it a mystery of Christ. As the bunch sustains many grapes held together by the woody stem, so likewise Christ holds many believers joined to Him by the wood of the Cross. The fig again is the Church which binds many faithful by a sweet embrace of charity, as the fig contains many seeds inclosed in one skin. The fig then has these significations, namely, love in its sweetness, unity in the close adhesion of its seeds. In the grape is shown patience, in that it is cast into the wine-press—joy, because wine maketh glad the heart of man—purity, because it is not mixed with water—and sweetness, in that it delighteth. The thorns and thistles are the heretics. And as a thorn or a thistle has sharp pricks on every part, so the Devil's servants, on whatsoever side you look at them, are full of wickedness. Thorns and thistles then of this sort cannot bear the fruits of the Church. And having instanced in particular trees, as the fig, the vine, the thorn, and the thistle, He proceeds to show that this is universally true, saying, Thus every good tree bringeth forth good fruit, but an evil tree bringeth forth evil fruit.

The bad (natural) tree cannot produce good fruit. But oddly, it can produce fruits that by all external tests are indistinguishable from the good ones: the act done from one's own separate and unredeemed, tho' 'moral' will, looks exactly like the act done by Christ in us. And oddly enough it is the tree's real duty to go on producing these imitation fruits till it recognises this futility and despairs and is made a new (spiritual) tree. The trouble in the XVIth century was that Luther - who intuited the truth - was fundamentally an uneducated man, a peasant type: and really let the whole question get immediately entangled with political and ecclesiological questions which were really quite irrelevant to it. But the whole question must now be raised again.

What most people who talk about Reunion don't realise is that continental Protestantism regards the Church of England as still theologically 'un-reformed' and the Lutheran-Anglican gap is really at present at least as wide as the Anglical-Roman. It is thus a three cornered affair.

Persons are still living who remember them,-their own actual disciples and successors,-who cannot therefore deny the lateness of their date. But, in fact, by their own works they are convicted, even as the Lord said. For since Marcion separated the New Testament from the Old, he is (necessarily) subsequent to that which he separated, inasmuch as it was only in his power to separate what was (previously) united.

[AD 407] John Chrysostom on Matthew 7:16
And by the figure of false prophets, here, I think He shadows out not the heretics, but them that are of a corrupt life, yet wear a mask of virtue; whom the generality are wont to call by the name of impostors. Wherefore He also said further,

By their fruits you shall know them. Matthew 7:16

For among heretics one may often find actual goodness, but among those whom I was mentioning, by no means.

What then, it may be said, if in these things too they counterfeit? Nay, they will be easily detected; for such is the nature of this way, in which I commanded men to walk, painful and irksome; but the hypocrite would not choose to take pains, but to make a show only; wherefore also he is easily convicted. Thus, inasmuch as He had said, there be few that find it, He clears them out again from among those, who find it not, yet feign so to do, by commanding us not to look to them that wear the masks only, but to them who in reality pursue it.

But wherefore, one may say, did He not make them manifest, but set us on the search for them? That we might watch, and be ever prepared for conflict, guarding against our disguised as well as against our open enemies: which kind indeed Paul also was intimating, when he said, that by their good words they deceive the hearts of the simple. Let us not be troubled therefore, when we see many such even now. Nay, for this too Christ foretold from the beginning.
[AD 407] John Chrysostom on Matthew 7:16
It does not seem to me that “false prophets” here refers to the heretics but rather to persons who live morally corrupt lives while wearing a mask of virtue. They are usually called frauds by most people. For this reason Jesus continued by saying, “By their fruits you will know them.” For it is possible to find some virtuous persons living among heretics. But among the corrupted of whom I speak it is in no way possible. “So what difference does it make,” Jesus says in effect, “if even among these false prophets some do put on a hypocritical show of virtue? Certainly they will soon be detected easily.” The nature of this road upon which he commanded us to walk is toilsome and hard. The hypocrite would seldom choose to toil but would prefer only to make a show. For this very reason the hypocrite is easily detected. When Jesus notes that “there are few who find it,” he distinguishes these from those who do not find the way yet pretend to find it. So do not look to the mask but to the behavioral fruits of those who pursue the narrow way.

[AD 430] Augustine of Hippo on Matthew 7:16
And in [the interpretation of] this passage we must be very much on our guard against the error of those who judge from these same two trees that there are two original natures, the one of which belongs to God, but the other neither belongs to God nor springs from Him. And this error has both been already discussed in other books [of ours] very copiously, and if that is still too little, will be discussed again; but at present we have merely to show that the two trees before us do not help them. In the first place, because it is so clear that He is speaking of men, that whoever reads what goes before and what follows will wonder at their blindness. Secondly, they fix their attention on what is said, A good tree cannot bring forth evil fruit, neither can a corrupt tree bring forth good fruit, and therefore think that neither can it happen that an evil soul should be changed into something better, nor a good one into something worse; as if it were said, A good tree cannot become evil, nor an evil tree good. But it is said, A good tree cannot bring forth evil fruit, neither can a corrupt tree bring forth good fruit. For the tree is certainly the soul itself, i.e. the man himself, but the fruits are the works of the man; an evil man, therefore, cannot perform good works, nor a good man evil works. If an evil man, therefore, wishes to perform good works, let him first become good. So the Lord Himself says in another passage more plainly: Either make the tree good, or make the tree bad. But if He were figuratively representing the two natures of such parties by these two trees, He would not say, Make: for who of the sons of men can make a nature? Then also in that passage, when He had made mention of these two trees, He added, You hypocrites, how can you, being evil, speak good things? As long, therefore, as any one is evil, he cannot bring forth good fruits; for if he were to bring forth good fruits, he would no longer be evil. So it might most truly have been said, snow cannot be warm; for when it begins to be warm, we no longer call it snow, but water. It may therefore come about, that what was snow is no longer so; but it cannot happen that snow should be warm. So it may come about, that he who was evil is no longer evil; it cannot, however, happen that an evil man should do good. And although he is sometimes useful, this is not the man's own doing; but it is done through him, in virtue of the arrangements of divine providence: as, for instance, it is said of the Pharisees, What they bid you, do; but what they do, do not consent to do. This very circumstance, that they spoke things that were good, and that the things which they spoke were usefully listened to and done, was not a matter belonging to them: for, says He, they sit in Moses' seat. It was, therefore, when engaged through divine providence in preaching the law of God, that they were able to be useful to their hearers, although they were not so to themselves. Respecting such it is said in another place by the prophet, They have sown wheat, but shall reap thorns; because they teach what is good, and do what is evil. Those, therefore, who listened to them, and did what was said by them, did not gather grapes of thorns, but through the thorns gathered grapes of the vine: just as, were any one to thrust his hand through a hedge, or were at least to gather a grape from a vine which was entangled in a hedge, that would not be the fruit of the thorns, but of the vine.

The question, indeed, is most rightly put, What are the fruits He would wish us to attend to, whereby we might know the tree? For many reckon among the fruits certain things which belong to the sheep's clothing, and in this way are deceived by wolves: as, for instance, either fastings, or prayers, or almsgivings; but unless all of these things could be done even by hypocrites, He would not say above, Take heed that you do not your righteousness before men, to be seen of them. And after prefixing this sentence, He goes on to speak of those very three things, almsgiving, prayer, fasting. For many give largely to the poor, not from compassion, but from vanity; and many pray, or rather seem to pray, while not keeping God in view, but desiring to please men; and many fast, and make a wonderful show of abstinence before those to whom such things appear difficult, and by whom they are reckoned worthy of honour: and catch them with artifices of this sort, while they hold up to view one thing for the purpose of deceiving, and put forth another for the purpose of preying upon or killing those who cannot see the wolves under that sheep's clothing. These, therefore, are not the fruits by which He admonishes us that the tree is known. For such things, when they are done with a good intention in sincerity, are the appropriate clothing of sheep; but when they are done in wicked deception, they cover nothing else but wolves. But the sheep ought not on this account to hate their own clothing, because the wolves often conceal themselves therein.

What the fruits are by the finding of which we may know an evil tree, the apostle tells us: Now the works of the flesh are manifest, which are these; adulteries, fornications, uncleanness, lasciviousness, idolatry, witchcraft, hatreds, variances, emulations, wrath, strife, seditions, heresies, envyings, murders, drunkenness, revellings, and such like: of the which I tell you before, as I have also told you in time past, that they which do such things shall not inherit the kingdom of God. And what the fruits are by which we may know a good tree, the very same apostle goes on to tell us: But the fruit of the Spirit is love, joy, peace, long-suffering, gentleness, goodness, faith, meekness, temperance. It must be known, indeed, that joy stands here in a strict and proper sense; for bad men are, strictly speaking, not said to rejoice, but to make extravagant demonstrations of joy: just as we have said above, that will which the wicked do not possess, stands in a strict sense where it is said, All things whatsoever ye would that men should do to you, do ye even so to them. In accordance with that strict sense of the word, in virtue of which joy is spoken of only in the good, the prophet also speaks, saying: Rejoicing is not for the wicked, says the Lord. So also faith stands, not certainly as meaning any kind of it, but true faith: and the other things which find a place here have certain resemblances of their own in bad men and deceivers; so that they entirely mislead, unless one has the pure and single eye by which he may know such things. It is accordingly the best arrangement, that the cleansing of the eye is first discussed, and then mention is made of what things were to be guarded against.
[AD 1107] Theophylact of Ohrid on Matthew 7:16
. The heretics are cunning and deceitful, which is why He says, "Beware." They produce sweet words and feign a decent life, but within lies the hook. "Sheep’s clothing" is meekness, which some pretend to employ, in order to flatter and to deceive. But they are recognized by their "fruit," that is, by their deeds and by their life. For though they can dissemble for a time, they are unmasked by those who are heedful.
[AD 220] Tertullian on Matthew 7:17
Now, if the world is a fault, as is the body, such must be its parts-faulty too; so in like manner must be the heaven and its celestial (contents), and everything which is conceived and produced out of it. And "a corrupt tree must needs bring forth evil fruit." The flesh of Christ, therefore, if composed of celestial elements, consists of faulty materials, sinful by reason of its sinful origin; so that it must be a part of that substance which they disdain to clothe Christ with, because of its sinfulness,-in other words, our own.

Now what He says is like this: they have nothing gentle nor sweet; it is the sheep only so far as the skin; wherefore also it is easy to discern them. And lest you should have any the least doubt, He compares it to certain natural necessities, in matters which admit of no result but one. In which sense Paul also said, The carnal mind is death; for it is not subject to the law of God, neither indeed can be.
[AD 407] John Chrysostom on Matthew 7:17
Even though Jesus seems to make virtually the same point a second time, it is hardly redundant. For in the second time around he prevents anyone from concluding, “The evil tree bears evil fruit, but it also bears good fruit, so as to make it difficult to recognize an evil tree, because the crop is of two kinds.” No. Jesus says, “This is not so. For the evil tree bears only evil fruits and would never13 bear good fruits. So also it is the same way with the opposite kind of tree.”What then? Is there no such thing as a good person who becomes corrupt? Or a corrupt person who becomes good? Isn’t life full of many examples of such reversals? But the Messiah is not saying that the evil person is incapable of changing or that the good person will never fail in anything. But he is saying that so long as a person is living in a degenerate way, he will not be able to generate good fruit. For he may indeed change to virtue, being evil, but while continuing in wickedness, he will not bear good fruit.
What then? Did not David, even though good, bear evil fruit? No, because he did not bear evil fruit while remaining good but while being changed. For if indeed he had remained continually good as he had been, he would not have produced the bad fruit. For it surely was not while abiding in the habits of excellence that he had the audacity to do the very things that he had the audacity to do.

[AD 407] John Chrysostom on Matthew 7:18
And if He states the same thing twice, it is not tautology. But, lest any one should say, Though the evil tree bear evil fruit, it bears also good, and makes the distinction difficult, the crop being twofold: This is not so, says He, for it bears evil fruit only, and never can bear good: as indeed in the contrary case also.

What then? Is there no such thing as a good man becoming wicked? And the contrary again takes place, and life abounds with many such examples.

But Christ says not this, that for the wicked there is no way to change, or that the good cannot fall away, but that so long as he is living in wickedness, he will not be able to bear good fruit. For he may indeed change to virtue, being evil; but while continuing in wickedness, he will not bear good fruit.

What then? Did not David, being good, bear evil fruit? Not continuing good, but being changed; since, undoubtedly, had he remained always what he was, he would not have brought forth such fruit. For not surely while abiding in the habit of virtue, did he commit what he committed.

Now by these words He was also stopping the mouths of those who speak evil at random, and putting a bridle on the lips of all calumniators. I mean, whereas many suspect the good by reason of the bad, He by this saying has deprived them of all excuse. For you can not say, 'I am deceived and beguiled;' since I have given you exactly this way of distinguishing them by their works, having added the injunction to go to their actions, and not to confound all at random.
[AD 407] John Chrysostom on Matthew 7:18
Jesus also said these things to shut the mouths of those who say nothing but slander and to reign in the lips of those who speak maliciously. For many are suspicious of good people because so many others are evil, but Jesus by this saying has deprived them of all excuse. For on this premise one would not even be able to say, “I am deceived and was misled.” For he has provided you a rule by which accurately to identify the frauds by their deeds. He has also commanded you to proceed on the basis of practices and not to mix up all cases at random.

(Verse 18 and following) A good tree cannot bear bad fruit, nor can a bad tree bear good fruit. Every tree that does not bear good fruit will be cut down and thrown into the fire. Therefore, by their fruits you will know them. Let us ask the heretics who claim that there are two contradictory natures, if according to their understanding, a good tree can never bear bad fruit, then how did Moses, a good tree, sin by striking the rock (Deut. 32)? And how did David, after killing Uriah, sleep with Bathsheba (2 Sam. 11)? And how did Peter, during the Passion of the Lord, deny Him, saying: 'I do not know the man' (Matt. 26:72)? Or what connection is there between Jethro, the father-in-law of Moses, a bad tree who did not believe in the God of Israel, giving good advice to Moses (Exod. 18)? And how did Achior, in speaking to Holofernes, say something useful (Judith 5)? And as the comedian said (which the Apostle confirmed): 'Evil company corrupts good morals' (1 Cor. 5). And when they do not find what to answer, let us infer that Judas (John 13) , once a good tree, bore bad fruits after betraying (or handing over) the Savior; and that Saul (Philippians 3) , a bad tree at the time he persecuted the Church of Christ, bore good fruits afterwards, when he was transformed from a persecutor into a vessel of election (Acts 9) . Therefore, a good tree does not bear bad fruits as long as it perseveres in the pursuit of goodness; and a bad tree remains in the fruits of sin as long as it does not convert to repentance. For no one remains in what he was, he begins to be what he has not yet begun.

A corrupt tree cannot bring forth good fruit as long as it is diseased. But if it has changed its condition, it can bring forth good fruit. See that He did not say, "it will not be able," but only that as long as it is corrupt it does not bear good fruit.

Others maintain that these things are said with reference to teachers of foreign doctrines and to people who mingle lies with the truth. Just as one cannot gather evil fruit from a tree that produces good fruit, neither can one gather grapes or figs from one that bears thorns; similarly, from an evil mindset, one does not hear good words, nor would you expect evil teaching to come from a pious teacher. But in protecting the others so that they may not be easily deluded, Jesus at the same time deters those who would attempt to teach evil things. For, he says, “every tree that does not bear good fruit is cut down and cast into the fire.” Just as fruitless trees are thrown into the fire, so human beings who do not bear the fruits of religion with their mouths will consequently receive punishment.

On this point, one must carefully avoid the error of those who think that they find in these two trees a reason for believing that there are two natures and that one of them belongs to the nature of God but that the other neither belongs to God nor depends on him. This error has been rather fully discussed in other books, and if that is not sufficient it will receive still further treatment later. But we must now show that these two trees furnish no argument in support of it. First of all, in this similitude the Lord is speaking about two kinds of persons. This is so obvious that if anyone will but read the passages in the context of those that precede and follow it, he will be amazed at the blindness of those who would misinterpret it impersonally. Again, they fix their attention on the saying, “A good tree cannot bear bad fruit, nor can a bad tree bear good fruit,” and then they think that an evil soul cannot be changed into a better or a good soul into a worse. As though, in truth, the saying were “A good tree cannot become a bad tree, nor a bad tree become a good tree!” But what has been said is that “a good tree cannot bear bad fruit, and a bad tree cannot bear good fruit.” The tree, of course, is the soul itself—that is, the person—and the fruits are the person’s works. So a bad person cannot perform good works, nor can a good person perform bad works.

[AD 407] John Chrysostom on Matthew 7:20
That He might not seem to introduce the threatening as His leading topic, but to be stirring up their mind in the way of admonition and counsel.

Here He seems to me to be hinting at the Jews also, who were exhibiting such fruits. Wherefore also He reminded them of the sayings of John, in the very same terms delineating their punishment. For he too said the very same, making mention to them of an axe, and of a tree cut down, and of unquenchable fire.

And though it appear indeed to be some single judgment, the being burnt up, yet if one examine carefully, these are two punishments. For he that is burnt is also cast of course out of God's kingdom; and this latter punishment is more grievous than the other. Now I know indeed that many tremble only at hell, but I affirm the loss of that glory to be a far greater punishment than hell. And if it be not possible to exhibit it such in words, this is nothing marvellous. For neither do we know the blessedness of those good things, that we should on the other hand clearly perceive the wretchedness ensuing on being deprived of them; since Paul, as knowing these things clearly, is aware, that to fall from Christ's glory is more grievous than all. And this we shall know at that time, when we shall fall into the actual trial of it.

But may this never be our case, O thou only-begotten Son of God, neither may we ever have any experience of this irremediable punishment. For how great an evil it is to fall from those good things, cannot indeed be accurately told: nevertheless, as I may be able, I will labor and strive by an example to make it clear to you, though it be but in some small degree.

Let us then imagine a wondrous child, having besides His virtue the dominion of the whole world, and in all respects so virtuous, as to be capable of bringing all men to the yearning of a father's affection. What theft do you think the father of this child would not gladly suffer, not to be cast out of His society? And what evil, small or great, would he not welcome, on condition of seeing and enjoying Him? Now let us reason just so with respect to that glory also. For no child, be he never so virtuous, is so desirable and lovely to a father, as the having our portion in those good things, and to depart and be with Christ. Philippians 1:23

No doubt hell, and that punishment, is a thing not to be borne. Yet though one suppose ten thousand hells, he will utter nothing like what it will be to fail of that blessed glory, to be hated of Christ, to hear I know you not, Matthew 25:12 to be accused for not feeding Him when we saw Him an hungered. Matthew 25:42 Yea, better surely to endure a thousand thunderbolts, than to see that face of mildness turning away from us, and that eye of peace not enduring to look upon us. For if He, while I was an enemy, and hating Him, and turning from Him, did in such wise follow after me, as not to spare even Himself, but to give Himself up unto death: when after all this I do not vouchsafe to Him so much as a loaf in His hunger, with what kind of eyes shall I ever again behold Him?

But mark even here His gentleness; in that He does not at all speak of His benefits, nor say, You have despised Him that has done you so much good: neither does He say, Me, who brought you from that which is not into being, who breathed into you a soul, and set you over all things on earth, who for your sake made earth, and heaven, and sea, and air, and all things that are, who had been dishonored by you, yea accounted of less honor than the devil, and did not even so withdraw Himself, but had innumerable thoughts for you after it all; who chose to become a slave, who was beaten with rods and spit upon, who was slain, who died the most shameful death, who also on high makes intercession for you, who freely gives you His Spirit, who vouchsafes to you a kingdom, who makes you such promises, whose will it is to be unto you Head, and Bridegroom, and Garment, and House, and Root, and Meat, and Drink, and Shepherd, and King, and who has taken you to be brother, and heir, and joint-heir with Himself; who has brought you out of darkness into the dominion of light. These things, I say, and more than these He might speak of, but He mentions none of these; but what? Only the sin itself.

Even here He shows His love, and indicates the yearning which He has toward you: not saying, Depart into the fire prepared for you, but prepared for the devil. And before He tells them what wrongs they had done, and neither so does He endure to mention all, but a few. And before these He calls the other sort, those who have done well, to signify from this too that He is blaming them justly.

What amount of punishment, then, is so grievous as these words? For if any one seeing but a man who was his benefactor an hungered, would not neglect him; or if he should neglect him, being upbraided with it, would choose rather to sink into the earth than to hear of it in the presence of two or three friends; what will be our feelings, on hearing these words in the presence of the whole world; such as He would not say even then, were He not earnestly accounting for His own doings? For that not to upbraid did He bring these things forward, but in self-defense, and for the sake of showing, that not without ground nor at random was He saying, depart from me; this is evident from His unspeakable benefits. For if He had been minded to upbraid, He would have brought forwards all these, but now He mentions only what treatment He had received.

10. Let us therefore, beloved, fear the hearing these words. Life is not a plaything: or rather our present life is a plaything, but the things to come are not such; or perchance our life is not a plaything only, but even worse than this. For it ends not in laughter, but rather brings exceeding damage on them who are not minded to order their own ways strictly. For what, I pray you, is the difference between children who are playing at building houses, and us when we are building our fine houses? What again between them making out their dinners, and us in our delicate fare? None, but just that we do it at the risk of being punished. And if we do not yet quite perceive the poverty of what is going on, no wonder, for we are not yet become men; but when we have become so, we shall know that all these things are childish.

For so those other things too, as we grow to manhood, we laugh to scorn; but when we are children we account them to be worth anxiety; and while we are gathering together potsherds and mire we think no less of ourselves than they who are erecting their great circuits of walls. Nevertheless they straightway perish and fall down, and not even when standing can they be of any use to us, as indeed neither can those fine houses. For the citizen of Heaven they cannot receive, neither can he bear to abide in them, who has his country above; but as we throw down these with our feet, so he too those by his high spirit. And as we laugh at the children, weeping at that overthrow, even so these also, when we are bewailing it all, do not laugh only, but weep also: because both their bowels are compassionate, and great is the mischief thence arising.

Let us therefore become men. How long are we to crawl on the earth, priding ourselves on stones and stocks? How long are we to play? And would we played only! But now we even betray our own salvation; and as children when they neglect their learning, and practise themselves in these things at their leisure, suffer very severe blows; even so we too, spending all our diligence herein, and having then our spiritual lessons required of us in our works, and not being able to produce them, shall have to pay the utmost penalty. And there is none to deliver us; though he be father, brother, what you will. But while these things shall all pass away, the torment ensuing upon them remains immortal and unceasing; which sort of thing indeed takes place with respect to the children as well, their father destroying their childish toys altogether for their idleness, and causing them to weep incessantly.

11. And to convince you that these things are such, let us bring before us wealth, that which more than anything seems to be worthy of our pains, and let us set against it a virtue of the soul (which soever you will), and then shall you see most clearly the vileness thereof. Let us, I say, suppose there are two men (and I do not now speak of injuriousness, but as yet of honest wealth); and of these two, let the one get together money, and sail on the sea, and till the land, and find many other ways of merchandise (although I know not quite, whether, so doing, he can make honest gains); nevertheless let it be so, and let it be granted that his gains are gotten with honesty; that he buys fields, and slaves, and all such things, and suppose no injustice connected therewith. But let the other one, possessing as much, sell fields, sell houses, and vessels of gold and silver, and give to the poor; let him supply the necessitous, heal the sick, free such as are in straits, some let him deliver from bonds, others let him release that are in mines, these let him bring back from the noose, those, who are captives, let him rescue from their punishment. Of whose side then would you be? And we have not as yet spoken of the future, but as yet of what is here. Of whose part then would ye be? His that is gathering gold, or his that is doing away with calamities? With him that is purchasing fields, or him who is making himself a harbor of refuge for the human race? Him that is clothed with much gold, or him that is crowned with innumerable blessings? Is not the one like some angel come down from Heaven for the amendment of the rest of mankind; but the other not so much as like a man, but like some little child that is gathering all together vainly and at random?

But if to get money honestly be thus absurd, and of extreme madness; when not even the honesty is there, how can such a man choose but be more wretched than any? I say, if the absurdity be so great; when hell is added thereto, and the loss of the kingdom, how great wailings are due to him, both living and dead?

12. Or will you that we take in hand some other part also of virtue? Let us then introduce again another man, who is in power, commanding all, invested with great dignity, having a gorgeous herald, and girdle, and lictors, and a large company of attendants. Does not this seem great, and meet to be called happy? Well then, against this man again let us set another, him that is patient of injuries, and meek, and lowly, and long suffering; and let this last be despitefully used, be beaten, and let him bear it quietly, and bless them that are doing such things.

Now which is the one to be admired, I pray you? He that is puffed up, and inflamed, or he that is self-subdued? Is not the one again like the powers above, that are so free from passion, but the other like a blown bladder, or a man who has the dropsy, and great inflammation? The one like a spiritual physician, the other, a ridiculous child that is puffing out his cheeks?

For why do you pride yourself, O man? Because you are borne on high in a chariot? Because a yoke of mules is drawing you? And what is this? Why, this one may see befalling mere logs of wood and stones. Is it that you are clothed with beautiful garments? But look at him that is clad with virtue for garments, and you will see yourself to be like withering hay, but him like a tree that bears marvellous fruit, and affords much delight to the beholders. For you are bearing about food for worms and moths, who, if they should set upon you, will quickly strip you bare of this adorning (for truly garments and gold and silver, are the one, the spinning of worms; the other earth and dust, and again become earth and nothing more): but he that is clothed with virtue has such raiment, as not only worms cannot hurt, but not even death itself. And very naturally; for these virtues of the soul have not their origin from the earth, but are a fruit of the Spirit; wherefore neither are they subject to the mouths of worms. Nay, for these garments are woven in Heaven, where is neither moth, nor worm, nor any other such thing.

Which then is better, tell me? To be rich, or to be poor? To be in power, or in dishonor? In luxury, or in hunger? It is quite clear; to be in honor, and enjoyment, and wealth. Therefore, if you would have the things and not the names, leave the earth and what is here, and find you a place to anchor in Heaven: for what is here is a shadow, but all things there are immovable, steadfast, and beyond any assault.

Let us therefore choose them with all diligent care, that we may be delivered from the turmoil of the things here, and having sailed into that calm harbor, may be found with our lading abundant, and with that unspeakable wealth of almsgiving; unto which God grant we may all attain, by the grace and love towards man of our Lord Jesus Christ, to whom be the glory and the might, world without end. Amen.
[AD 1107] Theophylact of Ohrid on Matthew 7:20
. He addresses the Jews, speaking the same words as did John. (Mt. 3:10) Jesus likens man to a tree. For by the introduction of a graft, a fruitless tree can bear fruit; so, too, a sinful and fruitless man when engrafted with Christ can bear fruits of virtue.
[AD 367] Hilary of Poitiers on Matthew 7:21-23
For obeying God's will and not calling on His name, shall find the way to the heavenly kingdom.

They even assure themselves of glory for their prophesying in teaching, for their casting out dæmons, for their mighty works; and hence promise themselves the kingdom of heaven, saying, Have we not prophesied in thy name?

But thus the hypocrites boasted, as though they spoke somewhat of themselves, and as though the power of God did not work all these things, being invoked; but reading has brought them the knowledge of His doctrine, and the name of Christ casts out the dæmons. Out of our own selves then is that blessed eternity to be earned, and out of ourselves must be put forth something that we may will that which is good, that we may avoid all evil, and may rather do what He would have us do, than boast of that to which He enables us. These then He disowns and banishes for their evil works, saying, Depart from me, ye that work iniquity.

[AD 407] John Chrysostom on Matthew 7:21
Wherefore said He not, but he that does my will? Because for the time it was a great gain for them to receive even this first; yea it was very great, considering their weakness. And moreover He intimated the one also by the other. And withal this may be mentioned, that in fact there is no other will of the Son besides that of the Father.

And here He seems to me to be censuring the Jews chiefly, laying as they did the whole stress upon the doctrines, and taking no care of practice. For which Paul also blames them, saying, Behold you are called a Jew, and restest in the law, and makest your boast of God, and know His will: Who then are these men? you ask. Many of them that believed received gifts such as he that was casting out devils, and was not with Him; such as Judas; for even he too, wicked as he was, had a gift. And in the Old Testament also this may be found, in that grace has oftentimes wrought upon unworthy persons, that it might do good to others. That is, since all men were not meet for all things, but some were of a pure life, not having so great faith, and others just the contrary; by these sayings, while He urges the one to show forth much faith, the others too He was summoning by this His unspeakable gift to become better men. Wherefore also with great abundance did He bestow that grace. For we wrought, it is said, many mighty works. But then will I profess unto them, I knew you not. For now indeed they suppose they are my friends; but then shall they know, that not as to friends did I give to them.

And why marvel if He has bestowed gifts on men that have believed on Him, though without life suitable to their faith, when even on those who have fallen from both these, He is unquestionably found working? For so Balaam was an alien both from faith and from a truly good life; nevertheless grace wrought on him for the service of other men. And Pharaoh too was of the same sort: yet for all that even to him He signified the things to come. And Nebuchadnezzar was very full of iniquity; yet to him again He revealed what was to follow after many generations. Daniel iii And again to the son of this last, though surpassing his father in iniquity, He signified the things to come, ordering a marvellous and great dispensation. Daniel v Accordingly because then also the beginnings of the gospel were taking place, and it was requisite that the manifestation of its power should be abundant, many even of the unworthy used to receive gifts. Howbeit, from those miracles no gain accrued to them; rather they are the more punished. Wherefore unto them did He utter even that fearful saying, I never knew you: there being many for whom His hatred begins already even here; whom He turns away from, even before the judgment.

Let us fear therefore, beloved; and let us take great heed to our life, neither let us account ourselves worse off, in that we do not work miracles now. For that will never be any advantage to us, as neither any disadvantage in our not working them, if we take heed to all virtue. Because for the miracles we ourselves are debtors, but for our life and our doings we have God our debtor.
[AD 407] John Chrysostom on Matthew 7:21
He said “whoever does the will of my Father” shall enter, not whoever does my will. Why? Nothing is insufficient if they do the will of the Father. What he did say was itself a very difficult thing to accept in view of their weakness. He implied that to do his Father’s will is to do his will. There is no other willing of the Son than the will of the Father. This may apply in particular to those who commit themselves in detail to legal rules yet take little thought for the actual embodiment of their better intentions. Elsewhere Paul confronts them directly when he says, “Consider this. You bear the name Jew, rely on the law, boast in God and know the will of God,” but in all this you derive no benefit as long as the actual fruits of good living are not present.

[AD 407] John Chrysostom on Matthew 7:21-23
(Hom. xxiv.) Wherein He seems to touch the Jews chiefly who placed every thing in dogmas; as Paul accuses them, If thou art called a Jew, and restest in the Law. (Rom. 2:17.)

He said not he that doth My will, but the will of my Father, for it was fit so to adapt it in the mean while to their weakness. But the one secretly implied the other, seeing the will of the Son is no other than the will of the Father.

See how He thus secretly brings in Himself. Here in the end of His Sermon He shows Himself as the Judge. The punishment that awaits sinners He had shown before, but now only reveals who He is that shall punish, saying, Many shall say to me in that day.

But there are that say that they spoke this falsely, and therefore were not saved. But they would not have dared to say this to the Judge in His presence. But the very answer and question prove that it was in His presence that they spoke thus. For having been here wondered at by all for the miracles which they wrought, and there seeing themselves punished, they say in wonderment, Lord, have we not prophesied in thy name? Others again say, that they did sinful deeds not while they thus were working miracles, but at a time later. But if this be so, that very thing which the Lord desired to prove would not be established, namely, that neither faith nor miracles avail ought where there is not a good life; as Paul also declares, If I have faith that I may remove mountains, but have not charity, I am nothing. (1 Cor. 13:2.)

For all are not alike fit for all things; these are of pure life, but have not so great faith; those again have the reverse. Therefore God converted these by the means of those to the showing forth much faith; and those that had faith He called by this unspeakable gift of miracles to a better life; and to that end gave them this grace in great richness. And they say, We have done many mighty works. But because they were ungrateful towards those who thus honoured them, it follows rightly, Then will I confess unto you, I never knew you.

He says to them, I never knew you, as it were, not at the day of judgment only, but not even then when ye were working miracles. For there are many whom He has now in abhorrence, and yet turns away His wrath before their punishment.

[AD 420] Jerome on Matthew 7:21
(Verse 21.) Not everyone who says to me, 'Lord, Lord,' will enter the kingdom of heaven, but only the one who does the will of my Father who is in heaven. As he said before, those who have a garment of good life should not be received on account of the wickedness of their teachings: so now he asserts the opposite, that even faith should not be given to those who, although they possess the integrity of faith, live wickedly and destroy the integrity of doctrine with evil deeds. For both the work is necessary for the servants of God, so that both the work is confirmed by speech, and speech is confirmed by works. This statement may seem contrary to that: No one can say, 'Jesus is Lord,' except in the Holy Spirit (1 Cor. 12:3). But it is customary for the sayings of the Scriptures to be taken for actions, as it is immediately approved in the following passages, refuting those who boast of having knowledge of the Lord without works, and they hear from the Savior: Depart from me, you workers of iniquity, I do not know you (Luke 13). And the Apostle speaks in this sense: They profess to know God, but by their deeds they deny Him (Titus 1:16).

Source: Commentary on Matthew
[AD 420] Jerome on Matthew 7:21-23
As He had said above that those who have the robe of a good life are yet not to be received because of the impiety of their doctrines; so now on the other hand, He forbids us to participate the faith with those who while they are strong in sound doctrine, destroy it with evil works. For it behoves the servants of God that both their work should be approved by their teaching and their teaching by their works. And therefore He says, Not every one that saith unto me, Lord, Lord, enters into the kingdom of heaven.

For Scripture uses to take words for deeds; according to which the Apostle declares, They make confession that they know God, but in works deny him. (Tit. 1:16.)

Otherwise; To prophesy, to work wonders, to cast out dæmons by divine power, is often not of his deserts who performs the works, but either the invocation of Christ's name has this force; or it is suffered for the condemnation of those that invoke, or for the benefit of those that see and hear, that however they despise the men who work the wonders, they may give honour to God. So Saul and Balaam and Caiaphas prophesied; the sons of Seæva in the Acts of the Apostles were seen to cast out dæmons; and Judas with the soul of a traitor is related to have wrought many signs among the other Apostles.

Emphatically, Then will I confess, for for long time He had forebore to say it.

Note that He says, I never knew you, as being against some that say that all men have always been among rational creatures.a

He says not, Who have worked, but, who work iniquity, that He should not seem to take away repentance. Ye, that is, who up to the present hour when the judgment is come, though ye have not the opportunity, yet retain the desire of sinning.

[AD 430] Augustine of Hippo on Matthew 7:21
But seeing that, however pure an eye one may have, i.e. with however single and sincere a heart one may live, he yet cannot look into the heart of another: whatever things could not have become apparent in deeds or words, are disclosed by trials. Now trial is twofold; either in the hope of obtaining some temporal advantage, or in the terror of losing it. And especially must we be on our guard, lest, when striving after wisdom, which can be found in Christ alone, in whom are hid all the treasures of wisdom and knowledge; — we must be on our guard, I say, lest, under the very name of Christ, we be deceived by heretics, or by any parties whatever defective in intelligence, and lovers of this world. For on this account He adds a warning, saying, Not every one that says unto Me, Lord, Lord, shall enter into the kingdom of heaven; but he that does the will of My Father which is in heaven, he shall enter into the kingdom of heaven: lest we should think that the mere fact of one saying to our Lord, Lord, Lord, belongs to those fruits; and from that he should seem to us to be a good tree. But those are the fruits, to do the will of the Father who is in heaven, in the doing of which He has condescended to exhibit Himself as an example.

But the question may fairly be started, how with this sentence the statement of the apostle is to be reconciled, where he says, No man speaking by the Spirit of God calls Jesus accursed; and no man can say that Jesus is the Lord, but by the Holy Ghost: for neither can we say that any who have the Holy Spirit will not enter into the kingdom of heaven, if they persevere onwards to the end; nor can we affirm that those who say, Lord, Lord, and yet do not enter into the kingdom of heaven, have the Holy Spirit. How then does no one say that Jesus is the Lord, but by the Holy Ghost, unless it is because the apostle has used the word say here in a strict and proper sense, so that it implies the will and understanding of him who says? But the Lord has used the word which He employs in a general sense: Not every one that says unto Me, Lord, Lord, shall enter into the kingdom of heaven. For he also who neither wishes nor understands what he says, seems to say it; but he properly says it, who gives expression to his will and mind by the sound of his voice: just as, a little before, what is called joy among the fruits of the Spirit is called so in a strict and proper sense, not in the way in which the same apostle elsewhere uses the expression, Rejoices not in iniquity: as if any one could rejoice in iniquity: for that transport of a mind making confused and boisterous demonstrations of joy is not joy; for this latter is possessed by the good alone. Hence those also seem to say it, who neither perceive with the understanding nor engage with the deliberate consent of the will in this which they utter, but utter it with the voice merely; and after this manner the Lord says, Not every one that says unto Me, Lord, Lord, shall enter into the kingdom of heaven. But truly and properly those parties say it whose utterance in speech really represents their will and intention; and it is in accordance with this signification that the apostle has said, No one can say that Jesus is the Lord, but by the Holy Ghost.
[AD 430] Augustine of Hippo on Matthew 7:21-23
(Serm. in Mont. ii. 24.) For even in the very name of Christ we must be on our guard against heretics, and all that understand amiss and love this world, that we may not be deceived, and therefore He says, Not every one that saith unto me, Lord, Lord. But it may fairly create a difficulty how this is to be reconciled with that of the Apostle, No man can say that Jesus is the Lord, but by the Holy Ghost. (1 Cor. 12:3.) For we cannot say that those who are not to enter into the kingdom of heaven have the Holy Spirit. But the Apostle uses the word 'say,' to express the will and understanding of him that says it. He only properly says a thing, who by the sound of his voice expresses his will and purpose. But the Lord uses the word in its ordinary sense, for he seems to say who neither wishes nor understands what he says.

(non occ.) Let us not therefore think that this belongs to those fruits of which He had spoken above, when one says to our Lord, Lord, Lord; and thence seems to us to be a good tree; the true fruit spoken of is to do the will of God; whence it follows, But who doeth the will of my Father which is in heaven, he shall enter into the kingdom of heaven.

(Serm. in Mont. ii. 25.) Hereto it also pertains that we be not deceived by the name of Christ not only in such as bear the name and do not the deeds, but yet more by certain works and miracles, such as the Lord wrought because of the unbelieving, but yet warned us that we should not be deceived by such to suppose that there was invisible wisdom where was a visible miracle; wherefore He adds, saying, Many shall say to me in that day.

(ubi sup.) Read also what things the Magi did in Egypt in withstanding Moses.

(Cont. Adv. Leg. ii. 4.) But never let it be said as the Manichees say, that the Lord spoke these things concerning the holy Prophets; He spoke of those who after the preaching of His Gospel seem to themselves to speak in His name not knowing what they speak.

(Mor. xx. 7.) By this sentence it is given to us to learn, that among men charity and humility, and not mighty works, are to be esteemed. Whence also now the Holy Church, if there be any miracles of heretics, despises them, because she knows that they have not the mark of holiness. And the proof of holiness is not to work miracles, but to love our neighbour as ourselves, to think truly of God, and of our neighbour better than of ourselves.

Here Jesus shows that He is Lord by saying, "Not every one that saith unto Me, Lord, Lord." Jesus in fact is saying that He is God. He teaches us that we derive no benefit from our faith if it is without works. "He that doeth the will of My Father." He did not mean, "that did the will of My Father on one occasion" but "that doeth the will of My Father continually until his death." And He did not say, "that doeth My will," lest He scandalize His listeners, but instead, "that doeth the will of My Father." For the will of a father and his son are one and the same, unless the son rebels.
[AD 1274] Pseudo-Chrysostom on Matthew 7:21-23
Otherwise; Having taught that the false prophets and the true are to be discerned by their fruits, He now goes on to teach more plainly what are the fruits by which we are to discern the godly from the ungodly teachers.

And what the will of God is the Lord Himself teaches, This is, (John 6:40.) He says, the will of him that sent me, that every man that seeth the Son and believeth on him should have eternal life. The word believe has reference both to confession and conduct. He then who does not confess Christ, or does not walk according to His word, shall not enter into the kingdom of heaven.

When, namely, He shall come in the majesty of His Father; when none shall any more dare with strife of many words either to defend a lie, or to speak against the truth, when each man's work shall speak, and his mouth be silent, when none shall come forward for another, but each shall fear for himself. For in that judgment the witnesses shall not be flattering men, but Angels speaking the truth, and the Judge is the righteous Lord; whence He closely images the cry of men fearful, and in straits, saying, Lord, Lord. For to call once is not enough for him who is under the necessity of terror.

But note that He says, in my name, not in My Spirit; for they prophesy in the name of Christ, but with the spirit of the Devil; such are the diviners. But they may be known by this, that the Devil sometimes speaks falsely, the Holy Spirit never. Howbeit it is permitted to the Devil sometimes to speak the truth, that he may commend his lying by this his rare truth. Yet they cast out dæmons in the name of Christ, though they have the spirit of his enemy; or rather, they do not cast them out, but seem only to cast them out, the dæmons acting in concert with them. Also they do mighty works, that is, miracles, not such as are useful and necessary, but useless and fruitless.

For great wrath ought to be preceded by great forbearance, that the sentence of God may be made more just, and the death of the sinners more merited. God does not know sinners because they are not worthy that they should be known of God; not that He altogether is ignorant concerning them, but because He knows them not for His own. For God knows all men according to nature, but He seems not to know them for that He loves them not, as they seem not to know God who do not serve Him worthily.

For death separates the soul from the body, but changes not the purpose of the heart.

(Verse 22.) Many say to me on that day: Lord, Lord, did we not prophesy in your name, and in your name cast out demons, and in your name perform many miracles? It is not always the merit of the one who does the prophesying, performing miracles, and casting out demons, but either the invocation of the name of Christ accomplishes this, or it is for the condemnation of those who invoke it and for the benefit of those who see and hear. So, even though people may despise those who perform miracles, they still honor God, for it is by invoking His name that such great wonders are accomplished. For both Saul (1 Samuel 10) and Balaam (Numbers 23) and Caiaphas (John 11) prophesied, not knowing what they were saying; and Pharaoh (Genesis 41) and Nebuchadnezzar (Daniel 2) knew the future through dreams. And in the Acts of the Apostles, the sons of Sceva were seen casting out demons (Acts 19). But it is also narrated that the apostle Judas, with the intention of a traitor, performed many signs among the other Apostles.

Source: Commentary on Matthew
[AD 430] Augustine of Hippo on Matthew 7:22
And besides, it belongs especially to the matter in hand, that, in striving after the contemplation of the truth, we should not only not be deceived by the name of Christ, by means of those who have the name and have not the deeds; but also not by certain deeds and miracles, for when the Lord performed of the same kind for the sake of unbelievers, He has warned us not to be deceived by such things, thinking that an invisible wisdom is present where we see a visible miracle. Hence He annexes the statement: Many will say to Me on that day, Lord, Lord, have we not prophesied in Your name, and in Your name have cast out devils, and in Your name done many wonderful works? And then will I say unto them, I never knew you: depart from Me, you that work iniquity. He will not, therefore, recognise any but the man that works righteousness. For He forbade also His own disciples themselves to rejoice in such things, viz. that the spirits were subject unto them: But rejoice, says He, because your names are written in heaven; I suppose, in that city of Jerusalem which is in heaven, in which only the righteous and holy shall reign. Do you not know, says the apostle, that the unrighteous shall not inherit the kingdom of God?
85. But perhaps some one may say that the unrighteous cannot perform those visible miracles, and may believe rather that those parties are telling a lie, who will be found saying, We have prophesied in Your name, and have cast out devils in Your name, and have done many wonderful works. Let him therefore read what great things the magi of the Egyptians did who resisted Moses, the servant of God; or if he will not read this, because they did not do them in the name of Christ, let him read what the Lord Himself says of the false prophets, speaking thus: Then, if any man shall say unto you, Lo, here is Christ, or there; believe it not. For there shall arise false Christs, and false prophets, and shall show great signs and wonders, insomuch that the very elect shall be deceived. Behold, I have told you before.
86. How much need, therefore, is there of the pure and single eye, in order that the way of wisdom may be found, against which there is the clamour of so great deceptions and errors on the part of wicked and perverse men, to escape from all of which is indeed to arrive at the most certain peace, and the immoveable stability of wisdom! For it is greatly to be feared, lest, by eagerness in quarrelling and controversy, one should not see what can be seen by few, that small is the disturbance of gainsayers, unless one also disturbs himself. And in this direction, too, runs that statement of the apostle: And the servant of the Lord must not strive; but be gentle unto all men, apt to teach, patient, in meekness instructing those that think differently; if God perhaps will give them repentance to the acknowledging of the truth. Blessed, therefore, are the peacemakers: for they shall be called the children of God.

Hence we must take special notice how terribly the conclusion of the whole sermon is introduced: Therefore, whosoever hears these sayings of Mine, and does them, is like unto a wise man, which built his house upon the rock. For no one confirms what he hears or understands, unless by doing. And if Christ is the rock, as many Scripture testimonies proclaim that man builds in Christ who does what he hears from Him. The rain descended, and the floods came, and the winds blew, and beat upon that house; and it fell not: for it was founded upon a rock. Such an one, therefore, is not afraid of any gloomy superstitions (for what else is understood by rain, when it is put in the sense of anything bad?), or of turnouts of men, which I think are compared to winds; or of the river of this life, as it were flowing over the earth in carnal lusts. For it is the man who is seduced by the prosperity that is broken down by the adversities arising from these three things; none of which is feared by him who has his house founded upon a rock, i.e. who not only hears, but also does, the Lord's commands. And the man who hears and does them not is in dangerous proximity to all these, for he has no stable foundation; but by hearing and not doing, he builds a ruin. For He goes on to say: And every one that hears these sayings of Mine, and does them not, shall be like a foolish man, which built his house upon the sand: and the rain descended, and the floods came, and the winds blew, and beat upon that house; and it fell: and great was the fall of it. And it came to pass, when Jesus had ended these sayings, the people were astonished at His doctrine: for He taught them as one having authority, and not as their scribes. This is what I said before was meant by the prophet in the Psalms, when he says: I will act confidently in regard of him. The words of the Lord are pure words: as silver tried and proved in a furnace of earth, purified seven times. And from this number, I am admonished to trace back those precepts also to the seven sentences which He has placed in the beginning of this sermon, when He was speaking of those who are blessed; and to those seven operations of the Holy Spirit, which the prophet Isaiah mentions; but whether the order before us, or some other, is to be considered in these, the things we have heard from the Lord are to be done, if we wish to build upon a rock.
[AD 444] Cyril of Alexandria on Matthew 7:22-23
There may be some who, in the beginning, believed rightly and assiduously labored at virtue. They may have even worked miracles and prophesied and cast out demons. And yet later they are found turning aside to evil, to self-assertive deception and desire. Of these Jesus remarks that he “never knew them.” He ranks them as equivalent to those who were never known by him at all. Even if they at the outset had lived virtuously, they ended up condemned. God knows those whom he loves, and he loves those who single-mindedly believe in him and do the things that please him.

And what the will of God is the Lord Himself teaches, “This is,” He says, “the will of him that sent me, that every man that seeth the Son and believeth on him should have eternal life.” The word believe has reference both to confession and conduct. He then who does not confess Christ, or does not walk according to His word, shall not enter into the kingdom of heaven.
He said not “he that doth” My “will,” but “the will of my Father,” for it was fit so to adapt it in the mean while to their weakness. But the one secretly implied the other, seeing the will of the Son is no other than the will of the Father.
When, namely, He shall come in the majesty of His Father; when none shall anymore dare with strife of many words either to defend a lie, or to speak against the truth, when each man’s work shall speak, and his mouth be silent, when none shall come forward for another, but each shall fear for himself. For in that judgment the witnesses shall not be flattering men, but Angles speaking the truth, and the Judge is the righteous Lord; whence He closely images the cry ofmen fearful, and in straits, saying, “Lord, Lord.” For to call once is not enough for him who is under the necessity of terror.
But there are that say that they spoke this falsely, and therefore were not saved. But they would not have dared to say this to the Judge in His presence. But the very answer and question prove that it was in His presence that they spoke thus. For having been here wondered at by all for the miracles which they wrought, and there seeing themselves punished, they say in wonderment, “Lord, have we not prophesied in thy name?” Others again say, that they did sinful deeds not while they thus were working miracles, but at a time later. But if this be so, that very thing which the Lord desired to prove would not be established, namely, that neither faith nor miracles avail ought where there isnot a good life; as Paul also declares, “If I have faith that I may remove mountains, but have not charity, I am nothing.” .
For all are not alike fit for all things; these are of pure life, but have not so great faith; those again have the reverse. Therefore God converted these bythe means of those to the showing forth much faith; and those that had faith He called by this unspeakable gift of miracles to a better life; and to that end gave them this grace in great richness. And they say, “We have done many mighty works.” But because they were ungrateful towards those who thus honoured them, it follows rightly, “Then will I confess unto you, I never knew you.”.
For great wrath ought to be preceded by great forbearance, that the sentence of God may be made more just, and the death of the sinners more merited. God does not know sinners because they are not worthy that they should be known of God; not that He altogether is ignorant concerning them, but because He knows them not for His own. For God knows all men according to nature, but He seems not to know them for that He loves them not, as they seem not to know God who do not serve Him worthily.
For death separates the soul from the body, but changes not the purpose of the heart.
[AD 420] Jerome on Matthew 7:23
(Verse 23.) And then I will confess to them, because I never knew you. He said explicitly, I will confess, because he had pretended to speak a long time ago: I do not know you. The Lord does not know those who perish. However, observe why he added, I never knew you, if, according to some, they have always lived among rational creatures.

[AD 407] John Chrysostom on Matthew 7:24
Having now, you see, finished all, having discoursed accurately of all virtue, and pointed out the pretenders to it, of various kinds, both such as for display fast and make prayers, and such as come in the sheep's hide; and them too that spoil it, whom He also called swine and dogs: He proceeds to signify how great is the profit of virtue even here, and how great the mischief of wickedness, by saying,

Whosoever therefore hears these sayings of mine, and does them, shall be likened unto a wise man.

As thus: What they shall suffer who do not (although they work miracles), you have heard; but you should know also what such as obey all these sayings shall enjoy; not in the world to come only, but even here. For whosoever, says He, hears these sayings of mine, and does them, shall be likened to a wise man.

Do you see how He varies His discourse; at one time saying, Not every one that says unto me, Lord, Lord, and revealing Himself; at another time, He that does the will of my Father; and again, bringing in Himself as judge, For many will say to me in that day, Lord, Lord, have we not prophesied in your name, and I will say, I know you not. And here again He indicates Himself to have the power over all, this being why He said, Whosoever hears these sayings of mine.

Thus whereas all His discourse had been touching the future; of a kingdom, and an unspeakable reward and consolation, and the like; His will is, out of things here also to give them their fruits, and to signify how great is the strength of virtue even in the present life. What then is this her strength? To live in safety, to be easily subdued by no terror, to stand superior to all that despitefully use us. To this what can be equal? For this, not even he that wears the diadem can provide for himself, but that man who follows after virtue. For he alone is possessed of it in full abundance: in the ebb and flow of the things present he enjoys a great calm. The truly marvellous thing being this, that not in fair weather, but when the storm is vehement, and the turmoil great, and the temptations continual, he cannot be shaken ever so little.
[AD 407] John Chrysostom on Matthew 7:24
Whereas his teaching has up to now largely focused on the future kingdom, its unspeakable rewards and its consolations, now he shifts his focus to the present life, its current fruits and how great is the strength of virtue within it. What then is its strength? It is living with security, not being easily overcome by any of life’s terrors and standing above all those who treat others maliciously. What could be as good as this? For not even the one who wears the royal crown would be able to furnish this for himself. But one who pursues the way of excellence can have this stability, for that one alone is possessed of this equilibrium in full abundance. In the crashing surf of the present circumstances such a one experiences a calm sea. This is amazing. It is when the storm is violent, the upheaval great and the temptations continual that such a person is not shaken in the slightest. This is not a way of living that applies to fair weather only. For he says, “The rain came down, the floods came, the winds blew, and they beat against that house. And it did not fall because it was founded upon the rock.”In referring to rain, floods and winds Jesus is speaking about all those human circumstances and misfortunes, such as false accusations, plots, bereavements, deaths, loss of family members, insults from others, and all the horrid things in life about which one could speak. Jesus says that a soul that pursues the way of excellence does not give in to any of these potential disasters. And the cause of this is that this soul has been founded upon the rock.
Now “rock” refers to the reliability of Jesus’ teaching. For his commands are stronger than any rock. They place one quite above all the human waves of life. For the one who guards these commands with care will excel not only over human beings when treated maliciously but even over the demons themselves in their plots.

For death separates the soul from the body, but changes not the purpose of the heart.

He said not, I will account him that hears and does, as wise; but, He shall be likened to a wise man. He then that is likened is a man; but to whom is he likened? To Christ; but Christ is the wise man who has built His house, that is, the Church, upon a rock, that is, upon the strength of the faith. The foolish man is the Devil, who has built his house, that is, all the ungodly, upon the sand, that is, the insecurity of unbelief, or upon the carnal, who are called the sand on account of their barrenness; both because they do not cleave together, but are scattered through the diversity of their opinions, and because they are innumerable. The rain is the doctrine that waters a man, the clouds are those from which the rain falls. Some are raised by the Holy Spirit, as the Apostles and Prophets, and some by the spirit of the Devil, as are the heretics. The good winds are the spirits of the different virtues, or the Angels who work invisibly in the senses of men, and lead them to good. The bad winds are the unclean spirits. The good floods are the Evangelists and teachers of the people; the evil floods are men full of an unclean spirit, and overflowing with many words; such are philosophers and the other professors of worldly wisdom, out of whose belly come rivers of dead water. The Church then which Christ has founded, neither the rain of false doctrine shall sap, nor the blast of the Devil overturn, nor the rush of mighty floods remove. Nor does it contradict this, that certain of the Church do fall; for not all that are called Christians, are Christ's, but, The Lord knows them that are his. (2 Tim. 2:19.) But against that house that the Devil has built comes down the rain of true doctrine, the winds, that is, the graces of the Spirit, or the Angels; the floods, that is, the four Evangelists and the rest of the wise; and so the house falls, that is, the Gentile world, that Christ may rise; and the ruin of that house was great, its errors broken up, its falsehoods laid open, its idols throughout the whole world broken down. He then is like unto Christ, who hears Christ's words, and does them; for he builds on a rock, that is, upon Christ, who is all good, so that on whatsoever kind of good any one shall build, he may seem to have built upon Christ. But as the Church built by Christ cannot be thrown down, so any such Christian who has built himself upon Christ, no adversity can overthrow, according to that, Who shall separate us from the love of Christ? (Rom. 8:35.) Like to the Devil is he that hears the words of Christ, and does them not. For words that are heard, and are not done, are likened to sand, they are dispersed and shed abroad. For the sand signifies all evil, or even worldly goods. For as the Devil's house is overthrown, so such as are built upon the sand are destroyed and fall. And great is that ruin if he have suffered any thing to fail of the foundation of faith; but not if he have committed fornication, or homicide, because he has whence he may arise through penitence, as David.

“For neither death nor life nor angels nor other things can separate us from the love of Christ.” Neither can the flooding of rivers, as in the lands of Egypt and Assyria, do harm. Only those are harmed who build on sand, who practice the wisdom of the world. The winds that blow are like the false prophets. All these, coming together in one place, “beat upon” the house. If it is founded on rock, they do no harm. “The way of a snake upon a rock” is not to be found. But in the form of temptations and persecutions, which may mount into a flood, they beat upon even the one who seems to be well-founded. The house falls if it does not have Christ as its basis and foundation. But the truly wise person builds one’s house “upon a rock.” This is the way the Lord builds his church—upon the rock, with steadfastness and strength. This is why “the gates of hell shall not prevail against it.” All the persecutions that fall upon that house accomplish nothing. The house is founded upon the rock.

[AD 407] John Chrysostom on Matthew 7:25
By rain here, and floods, and winds, He is expressing metaphorically the calamities and afflictions that befall men; such as false accusations, plots, bereavements, deaths, loss of friends, vexations from strangers, all the ills in our life that any one could mention. But to none of these, says He, does such a soul give way; and the cause is, it is founded on the rock. He calls the steadfastness of His doctrine a rock; because in truth His commands are stronger than any rock, setting one above all the waves of human affairs. For he who keeps these things strictly, will not have the advantage of men only when they are vexing him, but even of the very devils plotting against him. And that it is not vain boasting so to speak, Job is our witness, who received all the assaults of the devil, and stood unmoveable; and the apostles too are our witnesses, for that when the waves of the whole world were beating against them, when both nations and princes, both their own people and strangers, both the evil spirits, and the devil, and every engine was set in motion, they stood firmer than a rock, and dispersed it all.

And now, what can be happier than this kind of life? For this, not wealth, not strength of body, not glory, not power, nor ought else will be able to secure, but only the possession of virtue. For there is not, nay there is not another life we may find free from all evils, but this alone. And you are witnesses, who know the plots in king's courts, the turmoils and the troubles in the houses of the rich. But there was not among the apostles any such thing.

What then? Did no such thing befall them? Did they suffer no evil at any man's hand? Nay, the marvel is this above all things, that they were indeed the object of many plots, and many storms burst upon them, but their soul was not overset by them, nor thrown into despair, but with naked bodies they wrestled, prevailed, and triumphed.

Thou then likewise, if you be willing to perform these things exactly, shall laugh all ills to scorn. Yea, for if you be but strengthened with such philosophy as is in these admonitions, nothing shall be able to hurt you. Since in what is he to harm you, who is minded to lay plots? Will he take away your money? Well, but before their threatening you were commanded to despise it, and to abstain from it so exceedingly, as not so much as even to ask any such thing of your Lord. But does he cast you into prison? Why, before your prison, you were enjoined so to live, as to be crucified even to all the world. But does he speak evil? Nay, from this pain also Christ has delivered you, by promising you without toil a great reward for the endurance of evil, and making you so clear from the anger and vexation hence arising, as even to command you to pray for them. But does he banish you and involve you in innumerable ills? Well, he is making the crown more glorious for you. But does he destroy and murder you? Even hereby he profits you very greatly, procuring for you the rewards of the martyrs, and conducting you more quickly into the untroubled haven, and affording you matter for a more abundant recompence, and contriving for you to make a gain of the universal penalty. Which thing indeed is most marvellous of all, that the plotters, so far from injuring at all, do rather make the objects of their despite more approved. To this what can be comparable? I mean, to the choice of such a mode of life as this, and no other, is.

Thus whereas He had called the way strait and narrow; to soothe our labors on this side also, He signifies the security thereof to be great, and great the pleasure; even as of the opposite course great is the unsoundness, and the detriment. For as virtue even from things here was signified by Him to have her rewards, so vice also her penalties. For what I am ever saying, that I will say now also: that in both ways He is everywhere bringing about the salvation of His hearers on the one hand by zeal for virtue, on the other by hatred of vice. Thus, because there would be some to admire what He said, while they yield no proof of it by their works, He by anticipation awakens their fears, saying, Though the things spoken be good, hearing is not sufficient for security, but there is need also of obedience in actions, and the whole lies chiefly in this. And here He ends His discourse, leaving the fear at its height in them.

For as with regard to virtue, not only from the things to come did He urge them (speaking of a kingdom, and of Heaven, and an unspeakable reward, and comfort, and the unnumbered good things): but also from the things present, indicating the firm and immoveable quality of the Rock; so also with respect to wickedness, not from the expected things only does He excite their fears (as from the tree that is cut down, and the unquenchable fire, and the not entering into the kingdom, and from His saying, I know you not): but also from the things present, the downfall, I mean, in what is said of the house.
[AD 420] Jerome on Matthew 7:25
(Verse 25.) And the rain descended, and the rivers came, and the winds blew, and they rushed upon that house, and it did not fall. This rain which seeks to overthrow the house is the devil. The rivers, all the Antichrists, who are against Christ. The spiritual winds of wickedness in heavenly places (Ephesians 6).

Source: Commentary on Matthew
[AD 1107] Theophylact of Ohrid on Matthew 7:25
No virtue can be accomplished without God, which is why Jesus said, "I will liken him unto a wise man." The rock is Christ and the house is the soul. Therefore nothing will shake the man who builds his soul upon the doing of Christ’s commandments. Neither the rain, which is the devil who fell from heaven, nor the rivers, which are mean and harmful men filled to overflowing by such a rain, nor the winds, which are evil spirits, nor, in short, can any temptations cast down such a man.
[AD 407] John Chrysostom on Matthew 7:26
Wherefore also He made His argument more expressive, by trying its force in a parable; for it was not the same thing to say, The virtuous man shall be impregnable, but the wicked easily subdued, as to suppose a rock, and a house, and rivers, and rain, and wind, and the like.

And well did He call this man foolish: for what can be more senseless than one building a house on the sand, and while he submits to the labor, depriving himself of the fruit and refreshment, and instead thereof undergoing punishment? For that they too, who follow after wickedness, do labor, is surely manifest to every one: since both the extortioner, and the adulterer, and the false accuser, toil and weary themselves much to bring their wickedness to effect; but so far from reaping any profit from these their labors, they rather undergo great loss. For Paul too intimated this when he said, He that sows to his flesh, shall of his flesh reap corruption. Galatians 6:8 To this man are they like also, who build on the sand; as those that are given up to fornication, to wantonness, to drunkenness, to anger, to all the other things.

Such an one was Ahab, but not such Elijah (since when we have put virtue and vice along side of one another, we shall know more accurately the difference): for the one had built upon the rock, the other on the sand; wherefore though he were a king, he feared and trembled at the prophet, at him that had only his sheepskin. Such were the Jews but not the apostles; and so though they were few and in bonds, they exhibited the steadfastness of the rock; but those, many as they were, and in armor, the weakness of the sand. For so they said, What shall we do to these men? Acts 4:16 Do you see those in perplexity, not who are in the hands of others, and bound, but who are active in holding down and binding? And what can be more strange than this? Have you hold of the other, and art yet in utter perplexity? Yes, and very naturally. For inasmuch as they had built all on the sand, therefore also were they weaker than all. For this cause also they said again, What do ye, seeking to bring this man's blood upon us? Acts 5:28 What says he? Do you scourge, and are you in fear? Do you entreat despitefully, and art in dismay? Do you judge, and yet tremble? So feeble is wickedness.

But the Apostles not so, but how? We cannot but speak the things which we have seen and heard. Acts 4:20 Do you see a noble spirit? Do you see a rock laughing waves to scorn? Do you see a house unshaken? And what is yet more marvellous; so far from turning cowards themselves at the plots formed against them, they even took more courage, and cast the others into greater anxiety. For so he that smites adamant, is himself the one smitten; and he that kicks against the pricks, is himself the one pricked, the one on whom the severe wounds fall: and he who is forming plots against the virtuous, is himself the one in jeopardy. For wickedness becomes so much the weaker, the more it sets itself in array against virtue. And as he who wraps up fire in a garment, extinguishes not the flame, but consumes the garment; so he that is doing despite to virtuous men, and oppressing them, and binding them, makes them more glorious, but destroys himself. For the more ills you suffer, living righteously, the stronger are you become; since the more we honor self-restraint, the less we need anything; and the less we need anything, the stronger we grow, and the more above all. Such a one was John; wherefore him no man pained, but he caused pain to Herod; so he that had nothing prevailed against him that ruled; and he that wore a diadem, and purple, and endless pomp, trembles, and is in fear of him that is stripped of all, and not even when beheaded could he without fear see his head. For that even after his death he had the terror of him in full strength, hear what He says, This is John, whom I slew. Now the expression, I slew, is that of one not exulting, but soothing his own terror, and persuading his troubled soul to call to mind, that he himself slew him. So great is the force of virtue, that even after death it is more powerful than the living. For this same cause again, when he was living, they that possessed much wealth came unto him, and said, What shall we do? Is so much yours, and are you minded to learn the way of your prosperity from him that has nothing? The rich from the poor? The soldiers from him that has not even a house?

Such an one was Elias too: wherefore also with the same freedom did he discourse to the people. For as the former said, You generation of vipers; Matthew 3:7 so this latter, How long will you halt upon both your hips? And the one said, Have you killed, and inherited? the other, It is not lawful for you to have your brother Philip's wife. Mark 6:18

Do you see the rock? Do you see the sand; how easily it sinks down, how it yields to calamities? How it is overthrown, though it have the support of royalty, of number, of nobility? For them that pursue it, it makes more senseless than all.

And it does not merely fall, but with great calamity: for great indeed, He says, was the fall of it. The risk not being of trifles, but of the soul, of the loss of Heaven, and those immortal blessings. Or rather even before that loss, no life so wretched as he must live that follows after this; dwelling with continual despondencies, alarms, cares, anxieties; which a certain wise man also was intimating when he said, The wicked flees, when no man is pursuing. Proverbs 28:1 For such men tremble at their shadows, suspect their friends, their enemies, their servants, such as know them, such as know them not; and before their punishment, suffer extreme punishment here. And to declare all this, Christ said, And great was the fall of it; shutting up these good commandments with that suitable ending, and persuading even by the things present the most unbelieving to flee from vice.

For although the argument from what is to come be vaster, yet is this of more power to restrain the grosser sort, and to withdraw them from wickedness. Wherefore also he ended with it, that the profit thereof might make its abode in them.

Conscious therefore of all these things, both the present, and the future, let us flee from vice, let us emulate virtue, that we may not labor fruitlessly and at random, but may both enjoy the security here, and partake of the glory there: unto which God grant we may all attain, by the grace and love towards man of our Lord Jesus Christ, to whom be the glory and the might forever and ever. Amen.
[AD 407] John Chrysostom on Matthew 7:26
And he was right in calling this one a fool, because what could be more brainless than building a house on the sand? For such a one endures the work of building but deprives oneself of the fruit of one’s labor and of relaxation, experiencing punishment instead of benefit. For it is surely clear to everyone that even those who follow a wicked path have to sweat in labor. Even the robber, the adulterer and the false accuser have to work and strain so that they can bring their evil to completion. But they not only reap no benefit at all from these labors but also experience much loss. For Paul was implying this when he said, “The one who sows to one’s flesh will reap corruption from one’s flesh.” Who are these persons who build on the sand? Those who are given up to fornication, debauchery, drunkenness and anger—they are building on sand.

Concerning this, the prophet speaks confidently: He set my feet upon a rock (Psalm 40:3). And in another place: The rock is a refuge for rabbits, or porcupines (Psalm 104:8). For a timid animal takes refuge in the caves of the rocks: and with its rough skin and completely armed with javelins, it protects itself with such defense. Therefore, it is said to Moses at that time when he had fled from Egypt, and the rabbit was the Lord's: Stand in the opening of the rock, and you will see my back parts. (Exodus 33:21).

And it came to pass, when Jesus had finished these words, that the multitudes were astonished at his doctrine. The foundation which the Apostle, the architect, laid (I Cor. 3), is one, our Lord Jesus Christ. Upon this stable and firm foundation, and by itself a strong structure founded on massive support, is built the Church of Christ. Truly, every heretic's discourse is built for the purpose of collapsing upon a super unstable arena which cannot be securely cemented together nor reduced into one bond.

Spiritually understood, the one who rightly hears the word is contrasted with the builder who builds his house on sand. In time of temptation the house falls down. The onslaught of evil wind covers it with silt, and troubled waters flood into the soul. From this turbid flood stream of iniquity the house is shaken to its foundations. This should rouse us to become aware of the danger that comes in final judgment. Those who hear the Lord’s words are like a wise man building on rock. Those who do not follow the Lord’s words are likened to a foolish man building on sand. One who practices virtue is made thoroughly able “through Christ who strengthens him.” We receive everything from God who puts things right. From him comes wisdom and insight and union with all that is good. The bad person cannot claim God as cause of his own wickedness and stupidity. He makes himself like the fool when he withdraws from that which proceeds according to nature. He then turns toward what is unnatural.

For when temptation beats upon it, it falls with a crash. Unbelievers do not fall, for they are always lying on the ground. It is the believer who falls.

[AD 407] John Chrysostom on Matthew 7:28-29
Surely it was logical that they were in pain over the heavy weight of what he had said. They were stunned by the soaring level of the requirements that he had made. But now the strength of the one teaching was so great that he seized many of them and threw them into great amazement. Because of their pleasure in what he said, Jesus finally persuaded them not to leave as he finished speaking. For not even after he went down from the mountain did the hearers leave, but even then the whole audience followed him because of the great love that was shown in what he had said. But most of all they were astounded at his authority. For when he said these things, he did not refer to another, as even the prophet Moses did, but everywhere he showed that he himself was the One who had the authority to decide. For even when he was establishing laws Jesus continually added, “But I say to you.” And when he was reminding them of the final day of judgment, he showed that he himself is the One who will bring justice, both through the punishments and through the honors. This is what made such a commotion among them.

[AD 407] John Chrysostom on Matthew 7:28
Yet was it rather natural for them to grieve at the unpleasantness of His sayings, and to shudder at the loftiness of His injunctions; but now so great was the power of the Teacher, that many of them were even caught thereby, and thrown into very great admiration, and persuaded by reason of the sweetness of His sayings, not even when He ceased to speak, to depart from Him at all afterwards. For neither did the hearers depart, He having come down from the mountain, but even then the whole auditory followed Him; so great a love for His sayings had He instilled into them.

But they were astonished most of all at His authority. For not with reference to another, like the prophet and Moses, did He say what He said; but everywhere indicating Himself to be the person that had the power of deciding. For so, when setting forth His laws, He still kept adding, But I say unto you. And in reminding them of that day, He declared Himself to be the judge, both by the punishments, and by the honors.
[AD 420] Jerome on Matthew 7:28-29
For as the God and Lord of Moses himself, He of His own free will either added such things as seemed omitted in the Law, or even changed some; as above we read, It was said by them of old... But I say unto you. But the Scribes only taught the people what was written in Moses and the Prophets.

[AD 430] Augustine of Hippo on Matthew 7:28-29
(Serm. in Mont. in fin.) Otherwise; Rain, when it is put to denote any evil, is understood as the darkness of superstition; rumours of men are compared to winds; the flood signifies the lust of the flesh, as it were flowing over the land, and because what is brought on by prosperity is broken off by adversity. None of these things does he fear who has his house founded upon a rock, that is, who not only hears the command of the Lord, but who also does it. And in all these he submits himself to danger, who hears and does not. For no man confirms in himself what the Lord commands, or himself hears, but by doing it. But it should be noted, that when he said, He that heareth these words of mine, He shows plainly enough that this sermon is made complete by all those precepts by which the Christian life is formed, so that with good reason they that desire to live according to them, may be compared to one that builds on a rock.

(De Cons. Ev. ii. 19.) From that which is here said, He seems to have left the crowd of disciples—those out of whom He chose twelve, whom He called Apostles—but Matthew omits to mention it. For to His disciples only, Jesus seems to have held this Sermon, which Matthew recounts, Luke omits. That after descending into a plain He held another like discourse, which Luke records, and Matthew omits. Still it may be supposed, that, as was said above, He delivered one and the same Sermon to the Apostles, and the rest of the multitude present, which has been recorded by Matthew and Luke, in different words, but with the same truth of substance; and this explains what is here said of the multitude wondering.

(Serm. in Mont. ii. 25. i. 10, et seq.) This is what is signified in the eleventh Psalm, I will deal mightily with him; the words of the Lord are pure words, silver tried in the fire, purified of earth, purged seven times. (Ps. 12:5, 6.) The mention of this number admonishes me here to refer all these precepts to those seven sentences that He placed in the beginning of this Sermon; those, I mean, concerning the beatitudes. For one to be angry with his brother, without cause, or to say to him, Racha, or call him fool, is a sin of extreme pride, against which is one remedy, that with a suppliant spirit he should seek pardon, and not be puffed up with a spirit of boasting. Blessed, then, are the poor in spirit, for theirs is the kingdom of heaven. He is consenting to his adversary, that is, in showing reverence to the word of God, who goes to the opening His Father's will, not with contentiousness of law, but with meekness of religion, therefore, Blessed are the meek, for they shall inherit the earth. Also whosoever feels carnal delight rebel against his right will, will cry out, O wretched man that I am! who shall deliver me from the body of this death? (Rom. 7:24.) And in thus mourning he will implore the aid of the consoler; whence, Blessed are they that mourn, for they shall be comforted. What is there that can be thought of more toilsome than in overcoming an evil practice to cut off those members within us that hinder the kingdom of heaven, and not be broken down with the pain of so doing? To endure in faithful wedlock all things even the most grievous, and yet to avoid all accusation of fornication. To speak the truth, and approve it not by frequent oaths, but by probity of life. But who would be bold to endure such toils, unless he burned with the love of righteousness as with a hunger and thirst? Blessed, therefore, are they that hunger and thirst, for they shall be filled. Who can be ready to take wrong from the weak, to offer himself to any that asks him, to love his enemies, to do good to them that hate him, to pray for them that persecute him, except he that is perfectly merciful? Therefore, Blessed are the merciful, for they shall find mercy. He keeps the eye of his heart pure, who places the end of his good actions not in pleasing men, nor in getting those things that are necessary to this life, and who does not rashly condemn any man's heart, and whatever he gives to another gives with that intention with which he would have others give to him. Blessed, therefore, are the pure in heart, for they shall see God. It must needs be moreover, that by a pure heart should be found out the narrow way of wisdom, to which the guile of corrupt men is an obstacle; Blessed are the peaceful, for they shall he called the sons of God. But whether we take this arrangement, or any other, those things which we have heard from the Lord must be done, if we would build upon the rock.

This ending pertains both to the finishing the words, and the completeness of the doctrines. That it is said that the multitude wondered, either signifies the unbelieving in the crowd, who were astonished because they did not believe the Saviour's words; or is said of them all, in that they reverenced in Him the excellence of so great wisdom.

[AD 1274] Pseudo-Chrysostom on Matthew 7:28-29
The mind of man when satisfied reasonably brings forth praise, but when overcome, wonder. For whatever we are not able to praise worthily, we admire. Yet their admiration pertained rather to Christ's glory than to their faith, for had they believed on Christ, they would not have wondered. For wonder is raised by whatever surpasses the appearance of the speaker or actor; and thence we do not wonder at what is done or said by God, because all things are less than God's power. But it was the multitude that wondered, that is the common people, not the chief among the people, who are not wont to hear with the desire of learning; but the simple folk heard in simplicity; had others been present they would have broken up their silence by contradicting, for where the greater knowledge is, there is the stronger malice. For he that is in haste to be first, is not content to be second.

[AD 407] John Chrysostom on Matthew 7:29
And yet it was likely that this too would disturb them. For if, when they saw Him by His works showing forth His authority, the scribes were for stoning and persecuting Him; while there were words only to prove this, how was it other than likely for them to be offended? And especially when at first setting out these things were said, and before He had given proof of His own power? But however, they felt nothing of this; for when the heart and mind is candid, it is easily persuaded by the words of the truth. And this is just why one sort, even when the miracles were proclaiming His power, were offended; while the other on hearing mere words were persuaded and followed Him. This, I would add, the evangelist too is intimating, when he says, great multitudes followed Him, Matthew 8:1 not any of the rulers, nor of the scribes, but as many as were free from vice, and had their judgment uncorrupted. And throughout the whole gospel you see that such clave unto Him. For both while He spoke, they used to listen in silence, not making any intrusion, nor breaking in upon the connection of His sayings, nor tempting Him, and desiring to find a handle like the Pharisees; and after His exhortation they followed Him again, marvelling.

But do thou mark, I pray you, the Lord's consideration, how He varies the mode of profiting His hearers, after miracles entering on words, and again from the instruction by His words passing to miracles. Thus, both before they went up into the mountain, He healed many, preparing the way for His sayings; and after finishing that long discourse to the people, He comes again to miracles, confirming what had been said by what was done. And so, because He was teaching as one having authority, lest His so teaching should be thought boasting and arrogant, He does the very same in His works also, as having authority to heal; that they might no more be perplexed at seeing Him teach in this way, when He was working His miracles also in the same.
[AD 420] Jerome on Matthew 7:29
(Verse 29.) For he was teaching them as one having authority, and not as the scribes and Pharisees. For they taught the people, what was written in Moses and the Prophets. But Jesus, being like God and the Lord of Moses himself, for the freedom of his will, either added to the law what seemed less, or changing it, preached to the people, as we also read above: It was said to the ancients: But I say to you.

It was not the rulers who were astonished: how could that be when they viewed Him with spite? Rather it was the guileless multitude that was astonished. They did not marvel at His turns of phrase, but at His straightforward speech, and that He showed authority beyond that of the prophets. The prophets said, "Thus saith the Lord," but Christ spoke as God, "I say to you."
