1 Corinthians 3:1; 1 Corinthians 3:3-4
Brothers, I could not address you as spiritual but as worldly--mere infants in Christ.
You are still worldly. For since there is jealousy and quarreling among you, are you not worldly? Are you not acting like mere men?
For when one says, "I follow Paul," and another, "I follow Apollos," are you not mere men?
