Paul visits Jerusalem for the first time and meets with Peter and James (Galatians 1:18-19). Critical scholars generally agree that this is when Paul receives the creed he mentions in 1 Corinthians 15. He tells us about this in Galatians 1:18-19. “…what I also received…” (1 Corinthians 15:3). “Then three years later [referring to his conversion] I went up to Jerusalem to become acquainted with Cephas [Peter], and stayed with him fifteen days. But I did not see any other of the apostles except James, the Lord’s brother” (Galatians 1:18-19).
AD 46 or 49 – Paul visits Jerusalem a second time (Galatians 2:1-10). He meets with Peter, James, and John to confirm that he was preaching the same message as them. He reports, “They added nothing to me” (Galatians 2:6). [The reason these dates vary is because it is uncertain what Paul is referring to when he mentions, “after fourteen years.” It is either 14 years after his conversion (AD 32) or 14 years after his first trip to Jerusalem (AD 35).]
