Galatians 2:11-14 describes a serious confrontation between Paul and Peter. This incident takes place at Antioch some time before the Jerusalem conference in Acts 15. For Paul, Peter’s withdrawal from table fellowship is plainly hypocrisy. Peter has agreed Gentiles were not converts to Judaism and were fully saved apart from the Law. But under pressure from the “men from James” Peter withdraws from fellowship with the Gentiles. For Paul, this is nothing short of a breach of the agreement in the earlier private meeting (Gal 2:1-10).
Second, the incident may represent a break between Paul and the Antioch church. He continues his missionary efforts, eventually spending eighteen months in Corinth and three years in Ephesus. By Acts 18, the center of Gentile mission shifts from Antioch to Ephesus. Paul’s mission is responsible for planting many churches in the Lycus Valley by the end of the first century.
Third, the incident points out what we already know about Paul from Galatians 1—he is not under the authority of the Jerusalem church. Paul was commissioned by the risen Jesus directly and will not tolerate being told to change his gospel by men allegedly from James.
Why does the book of Acts not record the Antioch Incident? It is possible Luke thought his inclusion of the Jerusalem conference in Acts 15 was sufficient to summarize the problem of Gentile salvation. Luke tends to emphasize the unity of the church, so the incident at Antioch may have been passed over in order to highlight the unity of the Jerusalem conference.
Are there on-going ramifications of this split between Paul and Peter/Barnabas? James Dunn, for example, suggested this even forced Paul to move away from Antioch as the center of his mission, eventually settling in Ephesus for several years. Are there other unexpected results?
