1 Corinthians 1:12-13

And I need to bring this up because each of you is claiming loyalty to different preachers. Some are saying, “I am a disciple of Paul,” or, “I follow Apollos,” or, “I am a disciple of Peter the Rock,” and some, “I belong only to Christ.” But let me ask you, is Christ divided up into groups? Did I die on the cross for you? At your baptism did you pledge yourselves to follow Paul?
