For the word of the cross is foolishness to those who are perishing, but to us who are being saved it is the power of God.
In this first clause a concession is made. For as it might very readily be objected, that the gospel is commonly held in contempt, if it be presented in so bare and abject a form, Paul of his own accord concedes this, but when he adds, that it is so in the estimation of them that perish, he intimates that no regard must be paid to their judgment. For who would choose to despise the gospel at the expense of perishing? This statement, therefore, must be understood in this way: “However the preaching of the cross, as having nothing of human wisdom to recommend it to esteem, is reckoned foolishness by them that perish; in our view, notwithstanding, the wisdom of God clearly shines forth in it.” He indirectly reproves, however, the perverted judgment of the Corinthians, who, while they were, through seduction of words, too easily allured by ambitious teachers, regarded with disdain an Apostle who was endowed with the power of God for their salvation, and that simply because he devoted himself to the preaching of Christ. In what way the preaching of the cross is the power of God unto salvation, we have explained in commenting upon Romans 1:16
For it is written,
“I WILL DESTROY THE WISDOM OF THE WISE,
AND THE CLEVERNESS OF THE CLEVER I WILL SET ASIDE.”
He shows still farther, from the testimony of Isaiah, how unreasonable a thing it is that the truth of the gospel should be regarded with prejudice on the ground that the wise of this world hold it in contempt, not to say derision. For it is evident from the words of the Prophet, that their opinion is regarded as nothing in the account of God. The passage is taken from Isaiah 29:14, where the Lord threatens that he will avenge himself upon the hypocrisy of the people by this kind of punishment, that wisdom will perish from the wise, etc. Now the application of this to the subject in hand is this: “It is nothing new or unusual for men to form utterly absurd judgments, who appear in other respects to be distinguished for wisdom. For in this manner the Lord has been wont to punish the arrogance of those who, depending on their own judgment, think to be leaders to themselves and others. In this manner did He, among the Israelitish people of old, destroy the wisdom of those who were the leaders of the people. If this happened among a people, whose wisdom the other nations had occasion to admire, what will become of others?”
It is proper, however, to compare the words of the Prophet with those of Paul, and to examine the whole matter still more closely. The Prophet, indeed, makes use of neuter verbs when he says, Wisdom will perish and prudence will vanish, while Paul turns them into the active form, by making them have a reference to God. They are, however, perfectly the same in meaning. For this is a great prodigy which God declares he will exhibit, so that all will be filled with astonishment. Wisdom, therefore, perishes, but it is by the Lord’s destroying it: wisdom vanishes, but it is by the Lord’s covering it over and effacing it. As to the second term αθετεῖν, (which Erasmus renders reject,) as it is ambiguous, and is sometimes taken to mean efface, or expunge, or obliterate, I prefer to understand it in this sense here, so as to correspond with the Prophet’s word vanish, or be hid. At the same time, there is another reason that has weighed more with me,  — that the word reject was not in accordance with the subject, as will appear ere long. Let us see, then, as to the meaning.
The Prophet’s meaning, without doubt, is precisely this, that they would no longer have governors that would rule well, because the Lord will deprive them of sound judgment and intelligence. For as he elsewhere threatens to send blindness upon the whole nation (Isaiah 6:10,) so here, upon the leaders; which is just as though he were plucking the eyes out of the body. However this may be, a great difficulty arises from the circumstance, that the term wisdom or prudence was taken by Isaiah in a good sense, while Paul quotes it for an opposite purpose, as though the wisdom of men were condemned by God, as being perverted, and their prudence set aside as being mere vanity. I confess that it is commonly expounded in this way; but as it is certain that the oracles of the Holy Spirit are not perverted by the Apostles to meanings foreign to their real design, I choose rather to depart from the common opinion of interpreters than to charge Paul with falsehood. In other respects, too, the natural meaning of the Prophet’s words accords not ill with Paul’s intention; for if even the wisest become fools, when the Lord takes away a right spirit, what confidence is to be placed in the wisdom of men? Farther, as it is God’s usual way of punishing, to strike blind those who, following implicitly their own judgment, are wise in their own esteem, it is not to be wondered if carnal men, when they rise up against God, with the view of subjecting His eternal truth to their rashness, are turned into fools, and become vain in their imaginations. We now see with what appropriateness Paul makes use of this testimony. Isaiah declares that the vengeance of God upon all those that served God with their own inventions would be, that wisdom would vanish from their wise men. Paul, with the view of proving that the wisdom of this world is vain and worthless, when it exalts itself against God, adduces this testimony from Isaiah.
Where is the wise man? Where is the scribe? Where is the debater of this age?
This expression of triumph is added for the purpose of illustrating the Prophet’s testimony. Paul has not taken this sentiment from Isaiah, as is commonly thought, but speaks in his own person. For the passage which they point to (Isaiah 33:18) has nothing corresponding to the subject in hand, or nearly approaching to it. For in that passage, while he promises to the Jews deliverance from the yoke of Sennacherib, that he may magnify the more this great blessing from God, he shows how miserable is the condition of those that are oppressed by the tyranny of foreigners. He says, that they are in a constant fever of anxiety, from thinking themselves beset with scribes or questors, treasurers, and counters of towers. Nay more, he says, that the Jews were involved in such difficulties, that they were stirred up to gratitude by the very remembrance of them.  It is a mistake, therefore, to suppose that this sentence is taken from the Prophet.  The term world, ought not to be taken in connection with the last term merely, but also with the other two. Now, by the wise of this world, he means those who do not derive their wisdom from illumination by the Spirit through means of the word of God, but, endowed with mere worldly sagacity, rest on the assurance which it affords.
It is generally agreed, that by the term scribes is meant teachers. For as ספר, saphar among the Hebrews, means to relate or recount, and the noun derived from it, ספר, sepher, is used by them to signify a book or volume, they employ the term סופרימ, sopherim, to denote learned men, and those that are conversant with books; and, for the same reason, too, sopher regis is often used to denote a chancellor or secretary. The Greeks, following the etymology of the Hebrew term, have translated it γραμματεις, scribes  He appropriately gives the name of investigators  to those that show off their acuteness by starting difficult points and involved questions. Thus in a general way he brings to nothing man’s entire intellect, so as to give it no standing in the kingdom of God. Nor is it without good reason that he inveighs so vehemently against the wisdom of men, for it is impossible to express how difficult a thing it is to eradicate from men’s minds a misdirected confidence in the flesh, that they may not claim for themselves more than is reasonable. Now there is more than ought to be, if, depending even in the slightest degree upon their own wisdom, they venture of themselves to form a judgment.
Has not God made foolish the wisdom of the world?
By wisdom here he means everything that man can comprehend either by the natural powers of his understanding, or as deriving aid from practice, from learning, or from a knowledge of the arts. For he contrasts the wisdom of the world with the wisdom of the Spirit. Hence, whatever knowledge a man may come to have without the illumination of the Holy Spirit, is included in the expression, the wisdom of this world This he says God has utterly made foolish, that is, He has convicted it of folly. This you may understand to be effected in two ways; for whatever a man knows and understands, is mere vanity, if it is not grounded in true wisdom; and it is in no degree better fitted for the apprehension of spiritual doctrine than the eye of a blind man is for discriminating colors. We must carefully notice these two things — that a knowledge of all the sciences is mere smoke, where the heavenly science of Christ is wanting; and man, with all his acuteness, is as stupid for obtaining of himself a knowledge of the mysteries of God, as an ass is unqualified for understanding musical harmonies. For in this way he reproves the destructive pride of those who glory in the wisdom of the world so as to despise Christ, and the entire doctrine of salvation, thinking themselves happy when they are taken up with creatures; and he beats down the arrogance of those who, trusting to their own understanding, attempt to scale heaven itself.
There is also a solution furnished at the same time to the question, how it happens that Paul in this way throws down upon the ground every kind of knowledge that is apart from Christ, and tramples, as it were, under foot what is manifestly one of the chief gifts of God in this world. For what is more noble than man’s reason, in which man excels the other animals? How richly deserving of honor are the liberal sciences, which polish man, so as to give him the dignity of true humanity! Besides this, what distinguished and choice fruits they produce! Who would not extol with the highest commendations civil prudence  (not to speak of other things,) by which governments, principalities, and kingdoms are maintained? A solution of this question, I say, is opened up to view from the circumstance, that Paul does not expressly condemn either man’s natural perspicacity, or wisdom acquired from practice and experience, or cultivation of mind attained by learning; but declares that all this is of no avail for acquiring spiritual wisdom. And, certainly, it is madness for any one, confiding either in his own acuteness, or the assistance of learning, to attempt to fly up to heaven, or, in other words, to judge of the secret mysteries of the kingdom of God,  or to break through (Exodus 19:21) to a discovery of them, for they are hid from human view. Let us, then, take notice, that we must restrict to the specialities of the case in hand what Paul here teaches respecting the vanity of the wisdom of this world — that it rests in the mere elements of the world, and does not reach to heaven. In other respects, too, it holds true, that without Christ sciences in every department are vain, and that the man who knows not God is vain, though he should be conversant with every branch of learning. Nay more, we may affirm this, too, with truth, that these choice gifts of God — expertness of mind, acuteness of judgment, liberal sciences, and acquaintance with languages, are in a manner profaned in every instance in which they fall to the lot of wicked men.
For since in the wisdom of God the world through its wisdom did not come to know God, God was well-pleased through the foolishness of the message preached to save those who believe.
The right order of things was assuredly this, that man, contemplating the wisdom of God in his works, by the light of the understanding furnished him by nature, might arrive at an acquaintance with him. As, however, this order of things has been reversed through man’s depravity, God designs in the first place to make us see ourselves to be fools, before he makes us wise unto salvation, (2 Timothy 3:15;) and secondly, as a token of his wisdom, he presents to us what has some appearance of folly. This inversion of the order of things the ingratitude of mankind deserved. By the wisdom of God he means the workmanship of the whole world, which is an illustrious token and clear manifestation of his wisdom: God therefore presents before us in his creatures a bright mirror of his admirable wisdom, so that every one that looks upon the world, and the other works of God, must of necessity break forth in admiration of him, if he has a single spark of sound judgment. If men were guided to a right knowledge of God by the contemplation of his works, they would know God in the exercise of wisdom, or by a natural and proper method of acquiring wisdom; but as the whole world gained nothing in point of instruction from the circumstance, that God had exhibited his wisdom in his creatures, he then resorted to another method for instructing men.  Thus it must be reckoned as our own fault, that we do not attain a saving acquaintance with God, before we have been emptied of our own understanding.
He makes a concession when he calls the gospel the foolishness of preaching, having that appearance in the view of those foolish sages (μωροσόφοις) who, intoxicated with false confidence,  fear not to subject God’s sacred truth to their senseless criticism. And indeed in another point of view nothing is more absurd in the view, of human reason than to hear that God has become mortal — that life has been subjected to death — that righteousness has been veiled under the appearance of sin — and that the source of blessing has been made subject to the curse, that by this means men might be redeemed from death, and become partakers of a blessed immortality — that they might obtain life — that, sin being destroyed, righteousness might reign — and that death and the curse might be swallowed up. We know, nevertheless, in the meantime, that the gospel is the hidden wisdom, (1 Corinthians 2:7,) which in its height surmounts the heavens, and at which angels themselves stand amazed. Here we have a most beautiful passage, from which we may see how great is the blindness of the human mind, which in the midst of light discerns nothing. For it is true, that this world is like a theater, in which the Lord presents to us a clear manifestation of his glory, and yet, notwithstanding that we have such a spectacle placed before our eyes, we are stone-blind, not because the manifestation is furnished obscurely, but because we are alienated in mind, (Colossians 1:21,)and for this matter we lack not merely inclination but ability. For notwithstanding that God shows himself openly, it is only with the eye of faith that we can behold him, save only that we receive a slight perception of his divinity, sufficient to render us inexcusable.
Accordingly, when Paul here declares that God is not known through means of his creatures, you must understand him to mean that a pure knowledge of him is not attained. For that none may have any pretext for ignorance, mankind make proficiency in the universal school of nature; so far as to be affected with some perception of deity, but what God is, they know not, nay more, they straightway become vain in their imaginations, (Romans 1:21.) Thus the light shineth in darkness, (John 1:5.) It follows, then, that mankind do not err thus far through mere ignorance, so as not to be chargeable with contempt, negligence, and ingratitude. Thus it holds good, that all
have known God, and yet have not glorified him, (Romans 1:21,)
and that, on the other hand, no one under the guidance of mere nature ever made such proficiency as to know God. Should any one bring forward the philosophers as exceptions, I answer, that in them more especially there is presented a signal token of this our weakness. For there will not be found one of them, that has not from that first principle of knowledge, which I have mentioned, straightway turned aside into wandering  and erroneous speculations, and for the most part they betray a silliness worse than that of old wives. When he says, that those are saved that believe, this corresponds with the foregoing statement — that the gospel is the power of God unto salvation. Farther, by contrasting believers, whose number is small, with a blind and senseless world, he teaches us that we err if we stumble at the smallness of their number, inasmuch as they have been divinely set apart to salvation.
