This is a Bible study I wrote up several years ago on the books of Galatians. This letter is a passionate rebuke to churches that Paul has planted. He is upset because someone else (another preacher) has come through preaching “another gospel” and suggesting that Paul did not preach the whole gospel and did not really have true authority to preach the whole gospel. This suggests three questions that will surface through the letter:
What is Paul’s gospel?
What is his authority to preach this gospel?
What is the other gospel that Paul rejects?
