We are not told the reason for Peter’s fear. Previously, he did not fear Jewish Christians who advocated for circumcision (Acts 11:1–18). It does not make sense for him to be afraid now, especially when he was in Antioch rather than Joppa or Jerusalem. Maybe there was an unwritten agreement that he would eat separately from Gentile believers in order to advance the cause of Jewish mission.1 Perhaps he was informed of Jewish persecution that came in response to claims that Jewish Christians were forsaking old covenant food laws.2 In either case, his actions were not motivated by conviction but fear.
12 En effet, avant l'arrivée de quelques personnes de l'entourage de Jacques, il mangeait avec les païens, et, quand elles furent venues, il s'esquiva et se tint à l'écart, par crainte des circoncis.
