But neither Titus, who was with me, being a Greek, was compelled to be circumcised:

People's New Testament

2:3 But neither Titus, etc. Though Titus, a Gentile Christian and a minister, was with him, he was not compelled to be circumcised.

Wesley's Notes

2:3 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.

Jamieson-Fausset-Brown Bible Commentary

3. 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," Ga 2:4 ("certain of the sect of the Pharisees which believed," Ac 15:5), demanded his circumcision. The apostles, however, constrained by the firmness of Paul and Barnabas (Ga 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 son of a Jewess (Ac 16:1), he circumcised (Ac 16:3). Christianity did not interfere with Jewish usages, regarded merely as social ordinances, though no longer having their religious significance, in the case of Jews and proselytes, while the Jewish polity and temple still stood; after the overthrow of the latter, those usages naturally ceased. To have insisted on Jewish usages for Gentile converts, would have been to make them essential parts of Christianity. To have rudely violated them at first in the case of Jews, would have been inconsistent with that charity which (in matters indifferent) is made all things to all men, that by all means it may win some (1Co 9:22; compare Ro 14:1-7, 13-23). Paul brought Titus about with him as a living example of the power of the Gospel upon the uncircumcised heathen.

Matthew Henry's Concise Commentary

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.
