Galatians 2:9

"And when they perceived the grace that was given unto me, James and Cephas and John, they who were reputed to be pillars, gave to me and Barnabas the right hands of fellowship." He says not when they "heard," but when they "perceived," that is, were assured by the facts themselves, "they gave to me and Barnabas the right hands of fellowship." Observe how he gradually proves that his doctrine was ratified both by Christ and by the Apostles. For grace would neither have been implanted, nor been operative in him, had not his preaching been approved by Christ. Where it was for the purpose of comparison with himself, he mentioned Peter alone; here, when he calls them as witnesses, he names the three together, "Cephas, James, John," and with an encomium, "who were reputed to be pillars." Here again the expression "who were reputed" does not impugn the reality of the fact, but adopts the estimate of others, and implies that these great and distinguished men, whose fame was universal, bare witness that his preaching was ratified by Christ, that they were practically informed and convinced by experience concerning it. "Therefore they gave the right hands of fellowship" to me, and not to me only, but also to Barnabas, "that we should go unto the Gentiles, and they unto the Circumcision." Here indeed is exceeding prudence as well as an incontrovertible proof of their concord. For it shows that his and their doctrine was interchangeable, and that both approved the same thing, that they should so preach to the Jews, and he to the Gentiles. Wherefore he adds, "That we should go unto the Gentiles and they unto the Circumcision." Observe that here also he means by "the Circumcision," not the rite, but the Jews; whenever he speaks of the rite, and wishes to contrast it, he adds the word "uncircumcision;" as when he says, "For circumcision indeed profiteth, if thou be a doer of the law; but if thou be a transgressor of the law, thy circumcision is become uncircumcision." (Ro. ii: 25.) And again, "Neither circumcision availeth any thing, nor uncircumcision." But when it is to the Jews and not to the deed that he gives this name, and wishes to signify the nation, he opposes to it not uncircumcision in its literal sense, but the Gentiles. For the Jews are the contradistinction to the Gentiles, the Circumcision to the Uncircumcision. Thus when he says above, "For He that wrought for Peter into the Apostleship of the Circumcision, wrought for me also unto the Gentiles;" and again, "We unto the Gentiles and they unto the Circumcision," he means not the rite itself, but the Jewish nation, thus distinguishing them from the Gentiles.
