Ian J. Elmer shows that the Galatian crisis was initiated by a group of Judaising opponents acting under the direct authority of the Jerusalem church. The origins of this controversy can be traced back to the early dispute between the Hellenists and the Hebrews described in the Acts of the Apostles, which led to the expulsion of the Hellenists from Jerusalem and the establishment of the community in Antioch. Paulâ€TMs opponents apparently cited Jerusalem as the source of and the warrant for their Law-observant gospel. In Galatians, Paul alludes to events involving Judaising opponents that transpired in Jerusalem and Antioch prior to the outbreak of the crisis at Galatia. Thus, the immediate background of the crisis is found in the Jerusalem Council (Gal 2:1â€"10, Acts 15:1â€"35) and the incident at Antioch (Gal 2:11â€"14), its aftermath is played out in Corinth and Philippi.
