1 Corinthians 1:10-15

But I urge you, believers, by the name of our Lord Jesus Christ, that all of you be in full agreement in what you say, and that there be no divisions or factions among you, but that you be perfectly united in your way of thinking and in your judgment [about matters of the faith]. For I have been informed about you, my brothers and sisters, by those of Chloe’s household, that there are quarrels and factions among you. Now I mean this, that each one of you says, “I am [a disciple] of Paul,” or “I am [a disciple] of Apollos,” or “I am [a disciple] of Cephas (Peter),” or “I am [a disciple] of Christ.” Has Christ been divided [into different parts]? Was Paul crucified for you? Or were you baptized into the name of Paul? [Certainly not!] I thank God that I did not baptize any of you except Crispus and Gaius, [Acts 18:8; Rom 16:23] so that no one would say that you were baptized into my name.
