This letter from Paul is more than just a reminder of the church's life in Christ, and our life in the body. It's also an answer to challenges to Paul's authority who must have descended upon the Corinthian church. There were hints of this earlier, but now Paul is starting to address it more directly. He also reminds the young church of his love for them, and asks for that love to be returned. Church division is certainly not unique to our times, it was there from the start. As Paul shows us, though, it's important to address those issues. To handle the situation with love is his primary command, though that certainly becomes difficult when we are faced with actual opponents.
