1. See, e.g., 1:10-15: "I appeal to you, brothers, in the name of our Lord Jesus Christ, that all of you agree with one another so that there may be no divisions among you and that you may be perfectly united in mind and thought. My brothers, some from Chloe's household have informed me that there are quarrels among you. What I mean is this: One of you says, 'I follow Paul'; another, 'I follow Apollos'; another, 'I follow Cephas'; still another, 'I follow Christ.' Is Christ divided? Was Paul crucified for you? Were you baptized into the name of Paul? I am thankful that I did not baptize any of you except Crispus and Gaius, so no one can say that you were baptized into my name."
