“But I, brothers, could not address you as spiritual people, but as people of
the flesh, as infants in Christ. I fed you with milk, not solid food, for you were
not ready for it. And even now you are not yet ready, for you are still of the
flesh. For while there is jealousy and strife among you, are you not of the
flesh and behaving only in a human way? For when one says, “I follow Paul,”
and another, “I follow Apollos,” are you not being merely human?”
1 Corinthians 3:1-4 ESV
