69. 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.” 4526 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 shalt rebuke the wise in their own craftiness.” 4527 And again: “The Lord knoweth the thoughts of the wise, that they are foolish.” 4528 4526     1 Cor. i. 17–24 . 4527     1 Cor. iii. 18–20 . 4528     Ps. xciii. 11 .
