1Cor 1:29

“...so also, from the beginning, did God permit man to be swallowed up by the great whale, who was the author of transgression, not that he should perish altogether when so engulphed; but, arranging and preparing the plan of salvation, which was accomplished by the Word, through the sign of Jonah, for those who held the same opinion as Jonah regarding the Lord, and who confessed, and said, "I am a servant of the Lord, and I worship the Lord God of heaven, who hath made the sea and the dry land." [This was done] that man, receiving an unhoped-for salvation from God, might rise from the dead, and glorify God, and repeat that word which was uttered in prophecy by Jonah: "I cried by reason of mine affliction to the Lord my God, and He heard me out of the belly of hell;" [Jonah 2:2] and that he might always continue glorifying God, and giving thanks without ceasing, for that salvation which he has derived from Him, "that no flesh should glory in the Lord's presence;" [1 Corinthians 1:29] and that man should never adopt an opposite opinion with regard to God, supposing that the incorruptibility which belongs to him is his own naturally, and by thus not holding the truth, should boast with empty superciliousness, as if he were naturally like to God. For he (Satan) thus rendered him (man) more ungrateful towards his Creator, obscured the love which God had towards man, and blinded his mind not to perceive what is worthy of God, comparing himself with, and judging himself equal to, God.”

“The very Old Testament of the Creator itself, it is possible, no doubt, to charge with foolishness, and weakness, and dishonour and meanness, and contempt. What is more foolish and more weak than God's requirement of bloody sacrifices and of savoury holocausts? What is weaker than the cleansing of vessels and of beds? What more dishonourable than the discoloration of the reddening skin? What so mean as the statute of retaliation? What so contemptible as the exception in meats and drinks? The whole of the Old Testament, the heretic, to the best of my belief, holds in derision. For God has chosen the foolish things of the world to confound its wisdom. Marcion's god has no such discipline, because he does not take after (the Creator) in the process of confusing opposites by their opposites, so that "no flesh shall glory; but, as it is written, He that glorieth, let him glory in the Lord." In what Lord? Surely in Him who gave this precept.”

“"That no flesh should glory in the presence of God." For God doeth all things to this end, to repress vainglory and pride, to pull down boasting. "Do you, too," saith he, "employ yourselves in that work." He doth all, that we may put nothing to our own account; that we may ascribe all unto God. And have ye given yourselves over unto this person or to that? And what pardon will ye obtain? For God Himself hath shown that it is not possible we should be saved only by ourselves: and this He did from the beginning. For neither then could men be saved by themselves; but it required their compassing the beauty of the heaven, and the extent of the earth, and the mass of creation besides; if so they might be led by the hand to the great artificer of all the works. And He did this, repressing beforehand the self-conceit which was after to arise. Just as if a master who had given his scholar charge to follow wheresoever he might lead, when he sees him forestalling, and desiring to learn all things of himself, should permit him to go quite astray; and when he hath proved him incompetent to acquire the knowledge, should thereupon at length introduce to him what himself has to teach: so God also commanded in the beginning to trace Him by the idea which the creation gives; but since they would not, He, after showing by the experiment that they are not sufficient for themselves, conducts them again unto Him by another way. He gave for a tablet, the world; but the philosophers studied not in those things, neither were willing to obey Him, nor to approach unto Him by that way which Himself commanded. He introduces another way more evident than the former; one that might bring conviction that man is not of himself alone sufficient unto himself. For then scruples of reasoning might be started, and the Gentile wisdom employed, on their part whom He through the creation was leading by the hand; but now, unless a man become a fool, that is, unless he dismiss all reasoning and all wisdom, and deliver up himself unto the faith, it is impossible to be saved. You see that besides making the way easy, he hath rooted up hereby no trifling disease, namely, in forbidding to boast, and have high thoughts: "that no flesh should glory:" for hence came the sin, that men insisted on being wiser than the laws of God; not willing so to obtain knowledge as He had enacted: and therefore they did not obtain it at all. So also was it from the beginning. He said unto Adam, "Do such a thing, and such another thou must not do." He, as thinking to find out something more, disobeyed; and even what he had, he lost. He spake unto those that came after, "Rest not in the creature; but by means of it contemplate the Creator." They, forsooth, as if making out something wiser than what had been commanded, set in motion windings innumerable. Hence they kept dashing against themselves and one another, and neither found God, nor concerning the creature had any distinct knowledge; nor had any meet and true opinion about it. Wherefore again, with a very high hand, lowering their conceit, He admitted the uneducated first, showing thereby that all men need the wisdom from above. And not only in the matter of knowledge, but also in all other things, both men and all other creatures He hath constituted so as to be in great need of Him; that they might have this also as a most forcible motive of submission and attachment, lest turning away they should perish. For this cause He did not suffer them to be sufficient unto themselves. For if even now many, for all their indigency, despise Him, were the case not so, whither would they not have wandered in haughtiness? So that He stayed them from boasting as they did, not from any grudge to them, but to draw them away from the destruction thence ensuing.”

“So that no flesh should boast before Him. For this reason, he says, God acted in this way, to bring down the pride and boasting of those who were thinking about worldly things, and to convince them that they should ascribe everything received from Him to Him and not boast before Him. How then do you, Corinthians, take pride in this? Note in passing, we did not say without reason that those who were rejected were not deemed worthy of the preaching because of their pride.”

“Then he reveals the cause of all this, saying: He has not chosen the great but the lowly, so that no human being might boast in the presence of God, i.e., that no one may glory in his own worldly greatness as compared with the Lord: "Let not the wise man glory in his wisdom, let not the mighty man glory in his might, and let not the rich man glory in his riches" (Jer 9:23). For inasmuch as God did not subject the world to His faith by employing the great ones of the world but the lowly ones, man cannot boast that the world was saved by employing worldly greatness. However, since it might appear that worldly greatness did not originate from God, if He never employed it for His purposes, God employed a few and later a great number of the worldly great for the office of preaching. Hence a Gloss says that if the faithful fisherman had not come first, the humble orator could not have come later. Furthermore, it pertains to God's glory to draw the great of the world by means of the lowly.”
