Catholicism...

1 Corinthians 1
12 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."
13Is Christ divided? Was Paul crucified for you? Were you baptized into the name of Paul?

The Catholics seem to have read only the part that says "I follow Cephas," for they have set Peter as the head of the Church.
