Ambrosiaster : Here Paul is returning to what he said [in the first chapter]. — COMMENTARY ON PAUL'S EPISTLES Cyprian : Philosophers also profess that they pursue this virtue; but in their case the patience is as false as their wisdom also is. For whence can he be either wise or patient, who has neither known the wisdom nor the patience of God? since He Himself warns us, and says of those who seem to themselves to be wise in this world, "I will destroy the wisdom of the wise, and I will reprove the understanding of the prudent." Moreover, the blessed Apostle Paul, filled with the Holy Spirit, and sent forth for the calling and training of the heathen, bears witness and instructs us, saying, "See that no man despoil you through philosophy and vain deceit, after the tradition of men, after the elements of the world, and not after Christ, because in Him dwelleth all the fulness of divinity." And in another place he says: "Let no man deceive himself; if any man among you thinketh himself to be wise, let him become a fool to this world, that he may become wise. For the wisdom of this world is foolishness with God. For it is written, I will rebuke the wise in their own craftiness." And again: "The Lord knoweth the thoughts of the wise, that they are foolish." Wherefore if the wisdom among them be not true, the patience also cannot be true. For if he is wise who is lowly and meek-but we do not see that philosophers are either lowly or meek, but greatly pleasing themselves, and, for the very reason that they please themselves, displeasing God-it is evident that the patience is not real among them where there is the insolent audacity of an affected liberty, and the immodest boastfulness of an exposed and half-naked bosom. — Treatise IX. On the Advantage of Patience Cyprian : That the kingdom of God is not in the wisdom of the world, nor in eloquence, but in the faith of the cross, and in virtue of conversation. In the first Epistle of Paul to the Corinthians: "Christ sent me to preach, not in wisdom of discourse, lest the cross of Christ should become of no effect. For the word of the cross is foolishness to those who perish; but to those who are saved it is the power of God. For it is written, I will destroy the wisdom of the wise, and I will reprove the prudence of the prudent. Where is the wise? where is the scribe? where is the disputer of this world? Hath not God made foolish the wisdom of this world? Since indeed, in the wisdom of God, the world by wisdom knew not God, it pleased God by the foolishness of preaching to save them that believe. Because the Jews desire signs, and the Greeks seek for wisdom: but we preach Christ crucified, to the Jews indeed a stumbling-block, and to the Gentiles foolishness; but to them that are called, Jews and Greeks, Christ the power of God, and the wisdom of God." And again "Let no man deceive himself. If any man think that he is wise among you, let him become a fool to this world, that he may be wise. For the wisdom of this world is foolishness with God. For it is written, Thou shall rebuke the wise in their own craftiness." And again: "The Lord knoweth the thoughts of the wise, that they are foolish." — Treatise XII. Three Books of Testimonies Against the Jews. Isaac of Nineveh : Those who are tiny of body and those who, being wise in the world, abandon their knowledge and … become like babes of their own free will, will learn a wisdom which is not learned through study's labors. — ASCETICAL HOMILIES 72 John Chrysostom : "Let no man deceive himself." This also is in reference to that person, as thinking himself to be somewhat and flattering himself on wisdom. But that he might not seem to press on him at great length in a mere digression; he first throws him into a kind of agony and delivers him over unto fear, and then brings back his discourse to the common fault, saying, "If any man among you seemeth to be wise in this world, let him become a fool, that he may become wise." And this he doth afterwards with great boldness of speech, as having sufficiently beaten them down, and shaken with that fear the mind not of that unclean person only, but of all the hearers also: so accurately does he measure the reach of what he has to say. For what if a man be rich, what if he be noble; he is viler than all the vile, when made captive by sin. For as if a man were a king and enslaved to barbarians, he is of all men most wretched, so also is it in regard to sin: since sin is a barbarian, and the soul which hath been once taken captive she knoweth not how to spare, but plays the tyrant to the ruin of all those who admit her. — Homily on 1 Corinthians 9 John Chrysostom : "Let no man deceive himself; if any man thinketh 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 maketh 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 thy 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 hath 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 thy mind clear, and like one that is ignorant yield up thyself unto the faith, thou wilt 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. — Homily on 1 Corinthians 10 Tertullian : These are "the doctrines" of men and "of demons" produced for itching ears of the spirit of this world's wisdom: this the Lord called "foolishness," and "chose the foolish things of the world" to confound even philosophy itself. — The Prescription Against Heretics Tertullian : If you threaten an avenger, you threaten us with the Creator. "Ye must become fools, that ye may be wise." Wherefore? "Because the wisdom of this world is foolishness with God. — Against Marcion Book V
