Wisdom applied to divisions in the church

1 Brothers and sisters, I couldn't talk to you like spiritual people but like unspiritual people, like babies in Christ.
References for 1 Corinthians 3:1
      2 I gave you milk to drink instead of solid food, because you weren't up to it yet.
      3 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?
      4 When someone says, "I belong to Paul," and someone else says, "I belong to Apollos," aren't you acting like people without the Spirit?
