It should seem that Peter had been at Antioch some time; while he was there, there came down certain Jews from James, who was at Jerusalem: before they came Peter had communion with those Christians at Antioch, which were by birth Gentiles, and at meals eat as they eat, making no difference of meats, as the Jews did in obedience to the ceremonial law; but as soon as these zealots for the Jewish rites (though Christians) were come, Peter withdrew from the communion of the Gentile Christians, and was the head of a separate party; and all through fear of the Jews, lest they should, at their return to Jerusalem, make some report of him to his disadvantage, and expose him to the anger of the Jews.
