For the wisdom of this world is folly with God. For it is written, “He catches the wise in their craftiness,”

ἡ γὰρ σοφία τοῦ κόσμου τούτου μωρία παρὰ τῷ θεῷ ἐστιν. γέγραπται γάρ· ὁ δρασσόμενος τοὺς σοφοὺς ἐν τῇ πανουργίᾳ αὐτῶν·

Early Fathers

John Chrysostom (349-407)

Homilies on First Corinthians

Let no man deceive himself. If any man (ἐνὗμῖν omitted.) thinks that he is wise in this world, let him become a fool, that he may become wise. For the wisdom of this world is foolishness with God.

As I said before, having launched out before the proper time into accusation of the fornicator, and having half opened it obscurely in a few words, and made the man's conscience to quail, he hastens again to the battle with heathen wisdom, and to his accusations of those who were puffed up there-with, and who were dividing the Church: in order that having added what remained and completed the whole topic with accuracy, he might thenceforth suffer his tongue to be carried away with vehement impulse against the unclean person, having had but a preliminary skirmishing with him in what he had said before. For this, Let no man deceive himself, is the expression of one aiming chiefly at him and quelling him beforehand by fear: and the saying about the stubble, suits best with one hinting at him. And so does the phrase, Do you not know that you are the Temple of God, and the Spirit of God dwells in you? For these two things are most apt to withdraw us from sin; when we have in mind the punishment appointed for the sin; and when we reckon up the amount of our true dignity. By bringing forward then the hay and the stubble, he terrifies; but by speaking of the dignity of that noble birth which was theirs, he puts them to shame; by the former striving to amend the more insensible kind, by the latter the more considerate.

2. Let no man deceive himself; if any man thinks that he is wise in this world, let him become a fool.

As he bids one become, as it were, dead unto the world — and this deadness harms not at all, but rather profits, being made a cause of life:— so also he bids him become foolish unto this world, introducing to us hereby the true wisdom. Now he becomes a fool unto the world, who slights the wisdom from without, and is persuaded that it contributes nothing towards his comprehension of the faith. As then that poverty which is according to God is the cause of wealth, and lowliness, of exaltation, and to despise glory is the cause of glory; so also the becoming a fool makes a man wiser than all. For all, with us, goes by contraries.

Further: why said he not, Let him put off wisdom, but, Let him become a fool? That he might most exceedingly disparage the heathen instruction. For it was not the same thing to say, Lay aside your wisdom, and, become a fool. And besides, he is also training people not to be ashamed at the want of refinement among us; for he quite laughs to scorn all heathen things. And for the same sort of reason he shrinks not from the names, trusting as he does to the power of the things [which he speaks of].

Wherefore, as the Cross, though counted ignominious, became the author of innumerable blessings, and the foundation and root of glory unspeakable; so also that which was accounted to be foolishness became unto us the cause of wisdom. For as he who has learned anything ill, unless he put away the whole, and make his soul level and clear, and so offer it to him who is to write on it, will know no wholesome truth for certain; so also in regard of the wisdom from without. Unless thou turn out the whole and sweep your mind clear, and like one that is ignorant yield up yourself unto the faith, you will know accurately nothing excellent. For so those also who see imperfectly if they will not shut their eyes and commit themselves unto others, but will be trusting their own matters to their own faulty eyesight, they will commit many more mistakes than those who see not.

But how, you will say, are men to put off this wisdom? By not acting on its precepts.

3. Then, seeing that he bade men so urgently withdraw themselves from it, he adds the cause, saying, For the wisdom of this world is foolishness with God. For not only it contributes nothing, but it even hinders. We must then withdraw ourselves from it, as doing harm. Do you mark with what a high hand he carries off the spoils of victory, having proved that so far from profiting us at all, it is even an opponent?

And he is not content with his own arguments, but he has also adduced testimony again, saying, For it is written, Job 5:13 He takes the wise in their own craftiness. By craftiness, i.e. by their own arms getting the better of them. For seeing that they made use of their wisdom to the doing away of all need of God, by it and no other thing He refuted them, showing that they were specially in need of God. How and by what method? Because having by it become fools, by it, as was meet, they were taken. For they who supposed that they needed not God, were reduced to so great a strait as to appear inferior to fishermen and unlettered persons; and from that time forth to be unable to do without them. Wherefore he says, In their own craftiness He took them. For the saying I will destroy their wisdom, was spoken in regard to its introducing nothing useful; but this, who takes the wise in their own craftiness, with a view of showing the power of God.

Haydock Catholic Bible Commentary: 1 Corinthians

Let no man deceive himself. He next precautions them against themselves, and admonishes them to be upon their guard against curiosity, presumption, and self-love, and tells them to undervalue all other sciences, when put in competition with the science of salvation, the knowledge of the gospel. It hence appears, that some of the Corinthians were renowned for that human eloquence which the world so much esteems, and accordingly the apostle discovers to them the danger to which they are exposing themselves, by pursuing their present line of conduct. Calmet. — If any man among you seem to be wise in this world. He hints at some new teachers among them, (not at Apollo) who to gain the esteem of men, had introduced errors from profane philosophy, or the false principles of human wisdom, which, as he had told them before, was folly in the sight of God. He therefore tells such persons, that to become truly wise, they must become fools, by returning to the simplicity of the gospel-doctrine. Wi. — Let no man. That is, let no man say, I am for Paul, I am for Apollo. This language will introduce into the Church of God those various sects that existed amongst the philosophers, who were distinguished by the title of Platonics, Stoics, Peripatetic, and so on.
