Galatians 2:3

“But neither Titus, who was with me, being a Greek, etc..] There was such an agreement between the apostle, and his fellow apostles at Jerusalem, even about this article of the necessity of circumcision, and other rituals of the law of Moses, to salvation; that Titus, whom he brought along with him, an intimate companion of his in his travels, a fellow labourer with him in the ministry, and now upon the spot, though he was a Gentile, an uncircumcised person, yet even not he was compelled to be circumcised: the elders did not urge it, or insist upon it, as proper and necessary; they looked upon it as a thing indifferent, left him to his liberty, and made use of no forcible methods to oblige…”

“But--So far were they from regarding me as running in vain, that "not even Titus who was with me, who was a Greek (and therefore uncircumcised), was compelled to be circumcised." So the Greek should be translated. The "false brethren," Gal 2:4 ("certain of the sect of the Pharisees which believed," Act 15:5), demanded his circumcision. The apostles, however, constrained by the firmness of Paul and Barnabas (Gal 2:5), did not compel or insist on his being circumcised. Thus they virtually sanctioned Paul's course among the Gentiles and admitted his independence as an apostle: the point he desires to set forth to the Galatians. Timothy, on the other hand, as being a proselyte of the gate, and…”

“But neither Titus, who was with me - Paul introduces this case of Titus undoubtedly to show that circumcision was not necessary for salvation. It was a case just in point. He had gone up to Jerusalem with the express reference to this question. Here was a man whom he had admitted to the Christian church without circumcising him. He claimed that he had a right to do so; and that circumcision was not necessary in order for salvation. If it were necessary, it would have been proper that Titus should have been compelled to submit to it. But Paul that says this was not demanded; or if demanded by anyone, the point was yielded, and he was not compelled to be circumcised. It is to be remembered…”

“But neither was Titus who was with me - When I conversed with them. Compelled to be circumcised - A clear proof that none of the apostles insisted on the circumcising gentile believers. The sense is, And it is true, some of those false brethren would fain have compelled Titus to be circumcised; but I utterly refused it. Galatians 2:4”

“2:3 The Jerusalem apostles affirmed Paul’s message without qualification. They stood together on the same Good News—that God’s grace comes through faith in Christ, not through keeping the law. Clearly the Jerusalem apostles did not think that circumcision was necessary for a Gentile like Titus.”
