When Christianity had been preached for about eight years among the Jews only, and for about three years more among the Jews and devout Gentiles, the next stage of its progress was to the idolatrous Gentiles, in the year of Christ 44, and the fourth year of the emperor Claudius. Barnabas and Saul were selected for this purpose, and constituted in an extraordinary manner Apostles of the Gentiles, or uncircumcision. Barnabas was probably an elder of the first rank; he had seen Christ in the flesh, had been an eye witness of his being alive again after his crucifixion, and had received the Holy Spirit on the day of Pentecost, as being one of the hundred and twenty. Saul also, since his conversion had preached as a superior prophet, about seven years to the Jews only, and about two years more to the Jews and devout Gentiles. They had both been born in Gentile countries; and therefore may be supposed to have had more respect and affection for the Gentiles than most of the Jews, who were natives of Judea. Saul had been converted, and had hitherto preached chiefly on Gentile ground; and he had joined with Barnabas in teaching devout Gentiles for a whole year, at Antioch in Syria; by all which previous steps they were regularly conducted to the last gradation, or the conversion of the idolatrous Gentiles. But it was necessary, in order to the being an Apostle, to have seen our Lord Jesus Christ alive after his crucifixion, for the Apostles were in a peculiar manner the witnesses of his resurrection. Some have supposed that Saul saw the person of Jesus, when he was converted, near the city of Damascus; but others, who conceive from the history of this event, that this could not have been the case, as he was instantly struck blind, are of opinion that the season, when his Apostolic qualification and commission were completed, was that mentioned by himself, Acts xxii, 17, when he returned to Jerusalem the second time after his conversion, saw the Lord Jesus Christ in person, and received the command to go quickly out of Jerusalem, that he might be sent unto the Gentiles. See also Acts xxvi, 16–20, where he gives an account of the object of his commission. He also received a variety of gifts and powers, which, superadded to his own genius and learning, as well as fortitude and patience, eminently qualified him for the office of an Apostle, and for that particular exercise of it which was assigned to him. St. Paul is frequently called the _Apostle_, by way of eminence; and the _Apostle of the Gentiles_, because his ministry was chiefly employed for the conversion of the Gentiles, as that of St. Peter was for Jews, who is therefore styled the _Apostle of the circumcision_.
