Chap 1:
Paul opens Galatians addressing the people about God’s redeeming grace. Then flows into announcing his calling came from God, out of Judaism and persecuting Christians. He relates how his revelation of the Gospel came from Jesus Christ and urges the people to avoid those who were teaching a contrary Gospel, “the circumcision party,” and to close their ears to false angels. 1. (T. Berzon.) During his travels he encountered James the brother of Christ, but no other apostle.
