1 Corinthians 1:11-12

11For I have been informed about you, my brothers and sisters, by those of Chloe’s household, that there are quarrels and factions among you.

12Now 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.”
