14 But when I saw that they are not walking uprightly to the truth of the good news, I said to Peter before all, 'If thou, being a Jew, in the manner of the nations dost live, and not in the manner of the Jews, how the nations dost thou compel to Judaize?

Matthew Henry's Commentary on Galatians 2:14

Commentary on Galatians 2:11-14

(Read Galatians 2:11-14)

Notwithstanding Peter's character, yet, when Paul saw him acting so as to hurt the truth of the gospel and the peace of the church, he was not afraid to reprove him. When he saw that Peter and the others did not live up to that principle which the gospel taught, and which they professed, namely, That by the death of Christ the partition wall between Jew and Gentile was taken down, and the observance of the law of Moses was no longer in force; as Peter's offence was public, he publicly reproved him. There is a very great difference between the prudence of St. Paul, who bore with, and used for a time, the ceremonies of the law as not sinful, and the timid conduct of St. Peter, who, by withdrawing from the Gentiles, led others to think that these ceremonies were necessary.
