And the other Jews joined likewise with him; so that Barnabas also was carried away with their hypocrisy.
All Commentaries on Galatians 2:13 Go To Galatians 2
Augustine of Hippo
AD 430
Paul never fell into any pretense, for he everywhere observed a principle which seemed fitting both to Gentile and to Jewish churches, that he should nowhere take away a custom whose observation did not prevent the receiving of God’s kingdom…. Peter, however, when he came to Antioch, was rebuked by Paul not because he observed the Jewish custom in which he was born and reared, although he did not observe it among the Gentiles, but because he wanted to impose it on the Gentiles. This happened after seeing certain persons come from James—that is, from Judea, since James was the head of the church in Jerusalem. It was therefore in fear of those who still thought that salvation resided in these observances that Peter separated himself from the Gentiles and pretended to consent in imposing those burdens of servitude on the Gentiles.
