1 Corinthians 1:11-15

For it hath been signified unto me concerning you, my brethren, by them that are of the household of Chloe, that there are contentions among you. Now this I mean, that each 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 into the name of Paul? I thank God that I baptized none of you, save Crispus and Gaius; lest any man should say that ye were baptized into my name.
