1 Corinthians 1:
14 I thank God that I baptized none of you, but Crispus and Gaius;
15 Lest any should say that I had baptized in mine own name.
16 And I baptized also the household of Stephanas: besides, I know not whether I baptized any other.
17 For Christ sent me not to baptize, but to preach the gospel: not with wisdom of words, lest the cross of Christ should be made of none effect.
18 For the preaching of the cross is to them that perish foolishness; but unto us which are saved it is the power of God.
19 For it is written, I will destroy the wisdom of the wise, and will bring to nothing the understanding of the prudent.
1 Cor.1:14-19
