21 Then after fourteen years I went up again to Jerusalem with Barnabas, taking Titus along with me. 2 I went up by revelation; and I laid before them (but privately before those who were of repute) the gospel which I preach among the Gentiles, lest somehow I should be running or had run in vain. 3 But even Titus, who was with me, was not compelled to be circumcised, though he was a Greek. 4 But because of false brethren secretly brought in, who slipped in to spy out our freedom which we have in Christ Jesus, that they might bring us into bondage-- 5 to them we did not yield submission even for a moment, that the truth of the gospel might be preserved for you. 6 And from those who were reputed to be something (what they were makes no difference to me; God shows no partiality) --those, I say, who were of repute added nothing to me; 7 but on the contrary, when they saw that I had been entrusted with the gospel to the uncircumcised, just as Peter had been entrusted with the gospel to the circumcised 8 (for he who worked through Peter for the mission to the circumcised worked through me also for the Gentiles), 9 and when they perceived the grace that was given to me, James and Cephas and John, who were reputed to be pillars, gave to me and Barnabas the right hand of fellowship, that we should go to the Gentiles and they to the circumcised; 10 only they would have us remember the poor, which very thing I was eager to do.

Paul Rebukes Peter at Antioch

11 But when Cephas came to Antioch I opposed him to his face, because he stood condemned. 12 For before certain men came from James, he ate with the Gentiles; but when they came he drew back and separated himself, fearing the circumcision party. 13 And with him the rest of the Jews acted insincerely, so that even Barnabas was carried away by their insincerity. 14 But when I saw that they were not straightforward about the truth of the gospel, I said to Cephas before them all, "If you, though a Jew, live like a Gentile and not like a Jew, how can you compel the Gentiles to live like Jews?"

Commentary on Galatians 2:1-10

(Read Galatians 2:1-10)

Observe the apostle's faithfulness in giving a full account of the doctrine he had preached among the Gentiles, and was still resolved to preach, that of Christianity, free from all mixture of Judaism. This doctrine would be ungrateful to many, yet he was not afraid to own it. His care was, lest the success of his past labours should be lessened, or his future usefulness be hindered. While we simply depend upon God for success to our labours, we should use every proper caution to remove mistakes, and against opposers. There are things which may lawfully be complied with, yet, when they cannot be done without betraying the truth, they ought to be refused. We must not give place to any conduct, whereby the truth of the gospel would be reflected upon. Though Paul conversed with the other apostles, yet he did not receive any addition to his knowledge, or authority, from them. Perceiving the grace given to him, they gave unto him and Barnabas the right hand of fellowship, whereby they acknowledged that he was designed to the honour and office of an apostle as well as themselves. They agreed that these two should go to the heathen, while they continued to preach to the Jews; judging it agreeable to the mind of Christ, so to divide their work. Here we learn that the gospel is not ours, but God's; and that men are but the keepers of it; for this we are to praise God. The apostle showed his charitable disposition, and how ready he was to own the Jewish converts as brethren, though many would scarcely allow the like favour to the converted Gentiles; but mere difference of opinion was no reason to him why he should not help them. Herein is a pattern of Christian charity, which we should extend to all the disciples of Christ.

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.
