1Cor 3:20

“Next, he declares also the mode in which God took them, adding another testimony: "For the Lord," saith he, "knoweth the reasonings of men that they are vain." Now when the Wisdom which is boundless pronounces this edict concerning them, and declares them to be such, what other proof dost thou seek of their extreme folly? For men's judgments, it is true, in many instances fail; but the decree of God is unexceptionable and uncorrupt in every case.”

“The thoughts of the wise contribute nothing to a person's salvation.”

“If the Lord knows that the reasonings of men are vain, because there is nothing necessary and salvific in them, then how is it that you, Corinthians, harbor thoughts contrary to God and occupy yourselves with them as though they were profitable!”

“Secondly, he proves what he had said by citing two authorities: the first of these is from Jb (5:13); hence he says: He catches the wise in their own craftiness. Now the Lord catches the wise in their own craftiness, because when they lay crafty plans contrary to God, He frustrates them and fulfills His own plan. Thus, by the malice of Joseph's brothers attempting to prevent his ascendancy, it came to pass by divine providence that Joseph, after being sold, became a ruler in Egypt. Hence just before the words quoted, Job says: "He frustrates the devices of the crafty, so that their hands achieve no success"; because, as it says in Pr (21:30): "No wisdom, no understanding, no counsel, can avail against the Lord." The second authority is taken from Ps 94 (v. 11); hence he says: and again it is written: The Lord knows that the thoughts of the wise, i.e., according to the wisdom of the world, are futile, namely, because they do not reach unto the goal of human knowledge, which is the knowledge of divine truth. Hence Wis (13:1) says: "All men who are ignorant of God are foolish."”

“Knowing that their thoughts are vain, God rebukes their wisdom in order to prove that they are foolish, showing that what they thought was false is true and vice versa.”
