1 Corinthians 3:1-4

3:1 Brothers and sisters, I could not address you as people who live by the Spirit but as people who are still worldly—mere infants in Christ. 3:2 I gave you milk, not solid food, for you were not yet ready for it. Indeed, you are still not ready. 3:3 You are still worldly. For since there is jealousy and quarreling among you, are you not worldly? Are you not acting like mere humans? 3:4 For when one says, “I follow Paul,” and another, “I follow Apollos,” are you not mere human beings?
