Summary: St. Paul emphasizes the divine origin of the gospel without downplaying the importance of his fellow apostles. We understand this difficult passage in Galatians by looking at the entire letter, by remembering the apostolic witness to the Resurrection in 1 Cor 15, and by comparing the ministry of the apostle with that of the prophet Jeremiah. (Gal 1:11-19; 1 Cor 15; various passages from Jeremiah)
