1 Corinthians 3:2-4

New Century Version

² The teaching I gave you was like milk, not solid food, because you were not able to take solid food. And even now you are not ready. ³ You are still not spiritual, because there is jealousy and quarreling among you, and this shows that you are not spiritual. You are acting like people of the world. ⁴ One of you says, “I belong to Paul,” and another says, “I belong to Apollos.” When you say things like this, you are acting like people of the world.
