1 Corinthians 1:13-16
1:13 Is Christ divided? Paul wasn’t crucified for you, was he? Or were you in fact baptized in the name of Paul?
1:14 I thank God that I did not baptize any of you except Crispus and Gaius,
1:15 so that no one can say that you were baptized in my name!
1:16 (I also baptized the household of Stephanus. Otherwise, I do not remember whether I baptized anyone else.)
