Galatians 2:14

"But when I saw that they walked not uprightly according to the truth of the Gospel." Neither let this phrase disturb you, for in using it he does not condemn Peter, but so expresses himself for the benefit of those who were to be reformed by the reproof of Peter. "I said unto Cephas before them all." Observe his mode of correcting the others; he speaks "before them all," that the hearers might be alarmed thereby. And this is what he says, "If thou, being a Jew, livest as do the Gentiles, and not as do the Jews, how compellest thou the Gentiles to live as do the Jews?" But it was the Jews and not the Gentiles who were carried away together with Peter; why then does Paul impute what was not done, instead of directing his remarks, not against the Gentiles, but against the dissembling Jews? And why does he accuse Peter alone, when the rest also dissembled together with him? Let us consider the terms of his charge; "If thou, being a Jew, livest as do the Gentiles, and not as do the Jews, how compellest thou the Gentiles to live as do the Jews?" for in fact Peter alone had withdrawn himself. His object then is to remove suspicion from his rebuke; had he blamed Peter for observing the Law, the Jews would have censured him for his boldness towards their Teacher. But now arraigning him in behalf of his own peculiar disciples, I mean the Gentiles, he facilitates thereby the reception of what he has to say which he also does by abstaining from reproof of the others, and addressing it all to the Apostle. "If thou," he says, "being a Jew, livest as do the Gentiles, and not as do the Jews;" which almost amounts to an explicit exhortation to imitate their Teacher, who, himself a Jew, lived after the manner of the Gentiles. This however he says not, for they could not have received such advice, but under color of reproving him in behalf of the Gentiles, he discloses Peter's real sentiments. On the other hand, if he had said, Wherefore do you compel these Jews to Judaize? his language would have been too severe. But now he effects their correction by appearing to espouse the part, not of the Jewish, but of the Gentile, disciples; for rebukes, which are moderately severe, secure the readiest reception. And none of the Gentiles could object to Paul that he took up the defense of the Jews. The whole difficulty was removed by Peter's submitting in silence to the imputation of dissimulation, in order that he might deliver the Jews from its reality. At first Paul directs his argument to the character which Peter wore, "If thou, being a Jew:" but he generalizes as he goes on, and includes himself in the phrase...
