1 Corinthians 3:2-4

New Catholic Bible

² I fed you with milk, rather than with solid food that you were not ready to digest. Indeed, even now you are still not ready to receive it, ³ for you are still of the flesh.

As long as jealousy and rivalry continue among you, are you not of the flesh and acting as mere mortals? ⁴ Whenever someone says, “I belong to Paul,” and another asserts, “I belong to Apollos,” are you not acting in a merely human fashion?
