1 Corinthians 3:1-4

Brothers and sisters, I couldn’t talk to you like spiritual people but like unspiritual people, like babies in Christ. I gave you milk to drink instead of solid food, because you weren’t up to it yet. Now you are still not up to it because you are still unspiritual. When jealousy and fighting exist between you, aren’t you unspiritual and living by human standards? When someone says, “I belong to Paul,” and someone else says, “I belong to Apollos,” aren’t you acting like people without the Spirit?
