As described by Luke[8] the whole period was spent in the evangelization of Greek-speaking _Jews_, principally at Jerusalem. This was Paul's chosen field, worked under direction of "the apostles." Only against his will[9] was he driven for refuge to Tarsus, whence Barnabas, who had first introduced him to the apostles, brought him to Antioch. There was no Gentile mission until Barnabas and he were by that church made its 'apostles.' This mission was on express direction of "the Spirit" (Acts ix. 19-30; xi. 25 f.; xiii. 1-3; _cf._ xxii. 10-21). Paul's apostleship to the Gentiles begins, then, according to Luke, with the First Missionary Journey, when in company with (and at first in subordination to) Barnabas he evangelizes Cyprus and southern Galatia. The two are agents of Antioch, with "letters of commendation" from "the apostles and elders in Jerusalem" (Acts xv. 23-26). Paul is not an apostle of Christ in the same sense as the Twelve (_cf._ Acts i. 21 f.). He is a providential "vessel of the Spirit," ordained "by men and through men." His gospel is Peter's unaltered (_cf._ Acts xxvi. 16-23). Footnote 8: We apply the name to the writer of Luke-Acts without prejudice to the question of authorship. Footnote 9: Acts xxii. 10-21 is not quite consistent with xxvi. 15-18; but the general sense is clear. There is even wider disparity regarding the period of opposition. Luke slightly postpones its beginning and very greatly antedates its suppression. Moreover, he makes Paul accept a solution which his letters emphatically repudiate.
