In this second chapter of Galatians, there is a lot going on. Paul is establishing a fairly critical piece of theology that defined the Christian Church vs. historical Judaism: that the law convicts and brings death, but Christ gives life. He is trying to bring that live to the early church, but of course it was no small task. Even Peter (called “Cephas” several times here, the Aramaic version of his name) didn’t always get it right, and Paul got fiery about it. He called Peter out in front of others which was more than a rebuke of a man. It was a stand in favor of a united Church. Don’t worry, though. The two of them will still be working together!
