The biggest problem in the Corinthian church was division and disunity, fostered by pride. They could not agree on the best teachers, and they could not even agree on what constituted truth. Most of the problems they had were based on wrong thinking, which Paul addressed directly in the first three chapters of 1 Corinthians. At the end of chapter 3, he summarizes everything he has taught them so far, focusing on four things that would help to avoid division in the church: having a correct view of truth, of teachers, of life and the world, and a correct view of Jesus Christ. If they could agree on these essentials, unity could be maintained. The same is true for churches today.
