1 Corinthians 1:12-16

Now this I say, that every one of you saith, I am of Paul; and I of Apollos; and I of Cephas; and I of Christ.

Is Christ divided? was Paul crucified for you? or were ye baptized in the name of Paul?

I thank God that I baptized none of you, but Crispus and Gaius;

Lest any should say that I had baptized in mine own name.

And I baptized also the household of Stephanas: besides, I know not whether I baptized any other.
