- Progenies viperarum, quomodo potestis bona loqui, cum sitis mali ? ex abundantia enim cordis os loquitur.
- Greek New Testament (SBLGNT)
- γεννήματα ἐχιδνῶν, πῶς δύνασθε ἀγαθὰ λαλεῖν πονηροὶ ὄντες; ἐκ γὰρ τοῦ περισσεύματος τῆς καρδίας τὸ στόμα λαλεῖ.
Haydock's commentary
As the Pharisees were ever boasting of, and glorying in their ancestry, Christ here shews, that they have not much reason to boast, since their ancestors were but vipers. (St. Chrysostom)

The Fathers on this verse
St John Chrysostom Catena Aurea on verses 33-35
After his former answers He here again refutes them in another manner. This He does not in order to do away their charges against Himself, but desiring to amend them, saying, "Either make the tree good and his fruit good, or make the tree corrupt, and his fruit corrupt." As much as to say, None of you has said that it is an evil thing for a man to be delivered from daemons. But because they did not speak evil of the works, but said that it was the Devil that wrought them, He shews that this charge is contrary to the common sense of things, and human conceptions. And to invent such charges can only proceed from unbounded impudence.
St Jerome Catena Aurea on verses 33-35
Thus He holds them in a syllogism which the Greeks call "Aphycton," the unavoidable; which shuts in the person questioned on both sides, and presses him with either horn. If, He saith, the Devil be evil, he cannot do good works; so that if the works you see be good, it follows that the Devil was not the agent thereof. For it cannot be that good should come of evil, or evil of good.
St John Chrysostom Catena Aurea on verses 33-35
For the discerning of a tree is done by its fruits, not the fruits by the tree. "A tree is known by its fruits." For though the tree is the cause of the fruit, yet the fruit is the evidence of the tree. But ye do the very contrary, having no fault to allege against the works, ye pass a sentence of evil against the tree, saying that I have a daemon.
St Hilary of Poitiers Catena Aurea on verses 33-35
Thus did He at that present refute the Jews, who seeing Christ's works to be of power more than human, would notwithstanding not allow the hand of God. And at the same time He convicts all future errors of the faith, such as that of those who taking away from the Lord His divinity, and communion of the Father's substance, have fallen into divers heresies; having their habitation neither uncover the plea of ignorance as the Gentiles, nor yet within the knowledge of the truth. He figures Himself as a tree set in the body, seeing that through the inward fruitfulness of His power sprung forth abundant richness of fruit. Therefore either must be made a good tree with good fruits, or an evil tree with evil fruits; not that a good tree is to be made a bad tree, or the reverse; but that in this metaphor we may understand that Christ is either to be left in fruitlessness, or to be retained in the fruitfulness of good works. But to hold one's self neuter, to attribute some things to Christ, but to deny Him those things that are highest, to worship Him as God, and yet to deny Him a common substance with the Father, is blasphemy against the Spirit. In admiration of His so great works you dare not take away the name of God, yet through malevolence of soul you debase His high nature by denying His participation of the Father's substance.
St Augustine Catena Aurea on verses 33-35
Or this is an admonition to ourselves that we should be good trees that we may be able to bring forth good fruit; "Make the tree good, and its fruit good," is a precept of health to which obedience is necessary. But what He says, "Make the tree corrupt, and its fruit corrupt," is not a command to do, but a warning to take heed, spoken against those who being evil thought that they could speak good things, or have good works; this the Lord declares is impossible. The man must be changed first, that his works may be changed; for if the man remains in that wherein he is evil, he cannot have good works; if he remains in that wherein he is good, he cannot have evil works. Christ found us all corrupt trees, but gave power to become sons of God to them that believe on His name.
St John Chrysostom Catena Aurea on verses 33-35
But as speaking not for Himself but for the Holy Spirit, He accordingly rebukes them, saying, "Generation of vipers, how can ye being evil, speak good things?" This is both a rebuke of them, and a proof in their own characters of those things which had been said. As though He had said, So ye being corrupt trees cannot bring forth good fruit. I do not wonder then that you thus speak, for you are ill nourished of ill parentage, and have an evil mind. And observe He said not, How can ye speak good things, seeing ye are a generation of vipers? for these two are not connected together; but He said, "How can ye being evil speak good things? He calls them "generation of vipers," because they made boast of their forefathers; in order therefore to cut off this their pride, He shuts them out of the race of Abraham, assigning them a parentage corresponding to their characters.
Rabanus Maurus Catena Aurea on verses 33-35
Or the words, "Generation of vipers," may be taken as signifying children, or imitators of the Devil, because they had wilfully spoken against good works, which is of the Devil, and thence follows, "Out of the abundance of the heart the mouth speaketh." That man speaks out of the abundance of the heart who is not ignorant with what intention his words are uttered; and to declare his meaning more openly He adds, "A good man, out of the good treasure of his heart bringeth forth good things." The treasure of the heart is the intention of the thoughts, by which the Judge judges that work which is produced, so that sometimes though the outward work that is shewn seem great, yet because of the carelessness of a cold heart, they receive a little reward from the Lord.
St John Chrysostom Catena Aurea on verses 33-35
Herein also He shews His Godhead as knowing the hidden things of the heart; for not for words only, yea but for evil thoughts also they shall receive punishment. For it is the order of nature that the store of the wickedness which abounds within should be poured forth in words through the mouth. Thus when you shall hear any speaking evil, you must infer that his wickedness is more than what his words express; for what is uttered without is but the overflowing of that within; which was a sharp rebuke to them. For if that which was spoken by them were so evil, consider how evil must be the root from whence it sprung. And this happens naturally; for oftentimes the hesitating tongue does not suddenly pour forth all its evil, while the heart, to which none other is privy, begets whatsoever evil it will, without fear; for it has little fear of God. But when the multitude of the evils which are within is increased, the things which had been hidden then burst forth through the mouth. This is that He says, "Out of the abundance of the heart the mouth speaketh."
St Jerome Catena Aurea on verses 33-35
What He says, "The good man out of the good treasure of his heart, &c." is either pointed against the Jews, that seeing they blasphemed God, what treasure in their heart must that be out of which such blasphemy proceeded; or it is connected with what had gone before, that like as a good man cannot bring forth evil things, nor an evil man good things, so Christ cannot do evil works, nor the Devil good works.
Clement of Alexandria Who is the Rich Man that shall be saved?
XVII. But he who carries his riches in his soul, and instead of God’s Spirit bears in his heart gold or land, and is always acquiring possessions without end, and is perpetually on the outlook for more, bending downwards and fettered in the toils of the world, being earth and destined to depart to earth, whence can he be able to desire and to mind the kingdom of heaven, a man who carries not a heart, but land or metal, who must perforce be found in the midst of the objects he has chosen? For where the mind of man is, there is also his treasure. …
St Cyprian The Epistles of Cyprian, Epistle LIV
3. But, dearest brother, ecclesiastical discipline is not on that account to be forsaken, nor priestly censure to be relaxed, because we are disturbed with reproaches or are shaken with terrors; since Holy Scripture meets and warns us, saying, “But he who presumes and is haughty, the man who boasts of himself, who hath enlarged his soul as hell, shall accomplish nothing.” And again: “And fear not the words of a sinful man, for his glory shall be dung and worms. …
St Augustine On Christian Doctrine, It is Permissible for a Preacher to Deliver to the People What Has Been Written by a More Eloquent Man Than Himself
63. There are, indeed, some men who have a good delivery, but cannot compose anything to deliver. Now, if such men take what has been written with wisdom and eloquence by others, and commit it to memory, and deliver it to the people, they cannot be blamed, supposing them to do it without deception. For in this way many become preachers of the truth (which is certainly desirable), and yet not many teachers; for all deliver the discourse which one real teacher has composed, and there are no divisions among them. Nor are such men to be alarmed by the words of Jeremiah the prophet, through whom God denounces those who steal His words every one from his neighbor. For those who steal take what does not belong to them, but the word of God belongs to all who obey it; and it is the man who speaks well, but lives badly, who really takes the words that belong to another. …
St Augustine Our Lord’s Sermon on the Mount, Chapter XXIV
79. 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. …
St Augustine The Harmony of the Gospels, Of the Occasion on Which It Was Said to Him that He Cast Out Devils in the Power of Beelzebub, and of the Declarations Drawn Forth from Him by that Circumstance in Regard to the Blasphemy Against the Holy Spirit, and with Respect to the Two Trees; And of the Question Whether There is Not Some Discrepancy in These Sections Between Matthew and the Other Two Evangelists, and Particularly Between Matthew and Luke
85. Matthew proceeds with his narrative in the following terms: “And all the people were amazed, and said, Is not this the son of David? But when the Pharisees heard it, they said, This fellow doth not cast out devils but in Beelzebub, the prince of the devils. And Jesus knew their thoughts, and said unto them, Every kingdom divided against itself shall be brought to desolation;” and so on, down to the words, “By thy words thou shalt be justified, and by thy words thou shalt be condemned.” Mark does not bring in this allegation against Jesus, that He cast out devils in [the power of] Beelzebub, in immediate sequence on the story of the dumb man; but after certain other matters, recorded by himself alone, he introduces this incident also, either because he recalled it to mind in a different connection, and so appended it there, or because he had at first made certain omissions in his hist …
St Augustine Sermons on Selected Lessons of the New Testament, On the words of the Gospel, Matt. xiii. 52, ‘Therefore every scribe who hath been made a disciple to the kingdom of Heaven,’ etc
3. Peradventure some of you may say, “And how can a bad man speak what is good, when it is written, in the words of the Lord Himself, ‘A good man out of the good treasure of his heart bringeth forth good things, and an evil man out of the evil treasure of his heart bringeth forth evil things. Ye hypocrites, how can ye being evil speak good things?’” In the one place He says, “How can ye being evil speak good things?” in the other He says, “What they say, do, but do ye not after their works. For they say, and do not.” If “they say and do not,” they are evil; if they are evil, they cannot “speak good things;” how then are we to do what we hear from them, when we cannot hear from them what is good? Now take heed, Holy and Beloved, how this question may be solved. …
St Augustine Ten Homilies on the First Epistle of John, 1 John II. 18-27
8. But let us not be made sad: “They went out from us, but they were not of us; for if they had been of us, they would no doubt have continued with us.” If then they went out from us, they are antichrists; if they are antichrists, they are liars; if they are liars, they deny that Jesus is the Christ. Once more we come back to the difficulty of the question. Ask them one by one; they confess that Jesus is the Christ. The difficulty that hampers us comes of our taking what is said in the Epistle in too narrow a sense. At any rate ye see the question; this question puts both us and them to a stand, if it be not understood. Either we are antichrists, or they are antichrists; they call us antichrists, and say that we went out from them; we say the like of them. …
St Augustine Expositions on the Book of Psalms, Psalm V
12. “Their throat is an open sepulchre.” It may be referred to signify gluttony, for the sake of which men very often lie by flattery. And admirably has he said, “an open sepulchre:” for this gluttony is ever gaping with open mouth, not as sepulchres, which, on the reception of corpses, are closed up. This also may be understood hereby, that with lying and blind flattery men draw to themselves those whom they entice to sin; and as it were devour them, when they turn them to their own way of living. And when this happens to them, since by sin they die, those by whom they are led along, are rightly called open sepulchres: for themselves too are in a manner lifeless, being destitute of the life of truth; and they take in to themselves dead men, whom having slain by lying words and a vain heart, they turn unto themselves. …
St Augustine Expositions on the Book of Psalms, Psalm LVIII
2. But now to the present case let us come, if ye please. For the voice is that sweet voice, so well known to the ears of the Church, the voice of our Lord Jesus Christ, and the voice of His Body, the voice of the Church toiling, sojourning upon earth, living amid the perils of men speaking evil and of men flattering. Thou wilt not fear a threatener, if thou lovest not a flatterer. He therefore, of whom this is the voice, hath observed and hath seen, that all men speak justice. …
St John Chrysostom The Homilies of St. John Chrysostom, Matthew XII. 33
Then since He is arguing not for Himself, but for the Spirit, He hath dealt out His reproof even as a torrent, saying, “O generation of vipers, how can ye, being evil, speak good things?”
St John Chrysostom A Commentary on the Acts of the Apostles, Homily XXXII on Acts xv. 1
How then may one root out this evil passion? how subdue ( ὑποσκελίσειε ) this violent fever? Let us see whence it had its birth, and let us remove the cause. Whence is it wont to arise? From arrogance and much haughtiness. This cause then let us remove, and the disease is removed together with it. But what is arrogance? whence does it arise? for perhaps we are likely to have to go back to a still higher origin. But whatever course the reason of the thing may point out, that let us take, that we may go to the bottom of the mischief, and pluck it up by the roots. Whence then comes arrogance? From our not looking into our own concerns, but instead of that, busying ourselves about the nature of land, though we are not husbandmen, and the nature of gold, though we are not merchants, and concerning clothing, and everything else: while to ourselves and our own nature we never look at all. …
St John Chrysostom Homilies on Second Corinthians, Homily VI
[3.] Since then It hath given us life, let us remain living and not return again to the former deadness: for “Christ dieth no more; for the death that He died, He died unto sin once:” ( Rom. vi. 9, 10 .) and He will not have us always saved by grace: for so we shall be empty of all things. Wherefore He will have us contribute something also from ourselves. Let us then contribute, and preserve to the soul its life. And what is life in a soul, learn from the body. For the body too we then affirm to live, when it moves with a healthy kind of motion; but when it lies prostrate and powerless, or its motions are disorderly, though it retain the semblance of life or motion, such a life is more grievous than any death: and should it utter nothing sane but words of the crazy, and see one object instead of another, such a man again is more pitiable than those who are dead. …
4 more passages of the Fathers cite this verse. The Motif Searcher in the palace lists them all.
The Fathers are given as they wrote. Where a passage lays the Passion on the Jewish people, the Church teaches that it cannot be charged against all the Jews then living, nor against the Jews of today, and that all sinners were its authors (CCC 597, 598).
