So Paul runs into an interesting problem in Corinth (1 Corinthians 3). We are a tribal people and the church there has started forming tribes around their favorite speaker. Some prefer Apollos, some prefer Peter, some prefer Paul. It gets so bad that the church starts to splinter.
Sometimes a speaker will fuel the fire of division, insisting that is or her approach is the best approach, the real way to get into Christ. Other times, the division will appear on its own and nobody stops it, so it only gets worse.
Paul does not let this division occur. He commends his fellow speakers. He reminds the church that they are all after the same thing: the edification of the church and the worship of Jesus Christ.
Granted, it is only natural to have people you connect with more than others. God chose Israel as the nation He would show His power through. Jesus chose three disciples to do ministry with, and of those twelve He chose three (Peter, James, and John) to deliver special revelation to. I’m sure you have your core group of friends as well.
There’s absolutely nothing wrong with having people you are specially close with, either in a occupational or personal setting. However, the breakdown occurs when that bond closes doors to others.
Jesus was quick to welcome in followers the disciples pushed away. Paul was intentional about turning all glory away from himself and back to God.
In the end, we are all family.
Cheesy as it is, the song is right, “make new friends and keep the old, one is silver and the other is gold.”
