1 Corinthians 3:2-4

Revised Standard Version Catholic Edition

² I fed you with milk, not solid food; for you were not ready for it; and even yet you are not ready, ³ for you are still of the flesh. For while there is jealousy and strife among you, are you not of the flesh, and behaving like ordinary men? ⁴ For when one says, “I belong to Paul,” and another, “I belong to Apol′los,” are you not merely men?
