The gospel of the uncircumcision was committed unto me, as the gospel of the circumcision was unto Peter. I.e, of the circumcised Jews. See my canon21.
You will urge: Then Peter was not head of the Church, but Apostle and Pope of the Jews only. Some reply that this is said of the care and division of protection—that Peter was appointed to protect the Jews, Paul the Gentiles; and this especially, because he adds, He that wrought effectually in Peter to the apostleship of the circumcision, the same was mighty in me toward the Gentiles; which signifies: I was given the duty, the necessary graces, and apostolic gifts for my apostleship to the Gentiles.
Jerome"s answer is much better. He points out that at that time, at the very beginning of the Church, when there was still, as verse12shows, a wall of separation between Jews and Gentiles, Peter and Paul divided between them not power but works, so that Paul, hateful as he was to the Jews, might primarily and chiefly preach to the Gentiles, and Peter to the Jews. On occasion Paul preached to the Jews, as Acts ix. shows, and Peter to the Gentiles (Acts x.). Moreover, Peter transferred his see to Gentile Rome, as all historians, all the Fathers, the chronicles and monuments testify in common. See Bellarmine for these in detail. If any one after reading them still is in doubt, he must be too prejudiced or too impudent to form a sane judgment.
