19. Compare Ac 9:27, 28, wherein Luke, as an historian, describes more generally what Paul, the subject of the history, himself details more particularly. The history speaks of "apostles"; and Paul's mention of a second apostle, besides Peter, reconciles the Epistle and the history. At Stephen's martyrdom, and the consequent persecution, the other ten apostles, agreeably to Christ's directions, seem to have soon (though not immediately, Ac 8:14) left Jerusalem to preach elsewhere. James remained in charge of the mother church, as its bishop. Peter, the apostle of the circumcision, was present during Paul's fifteen days' stay; but he, too, presently after (Ac 9:32), went on a circuit through Judea.
      James, the Lord's brother--This designation, to distinguish him from James the son of Zebedee, was appropriate while that apostle was alive. But before Paul's second visit to Jerusalem (Ga 2:1; Ac 15:1-4), he had been beheaded by Herod (Ac 12:2). Accordingly, in the subsequent mention of James here (Ga 2:9, 12), he is not designated by this distinctive epithet: a minute, undesigned coincidence, and proof of genuineness. James was the Lord's brother, not in our strict sense, but in the sense, "cousin," or "kinsman" (Mt 28:10; Joh 20:17). His brethren are never called "sons of Joseph," which they would have been had they been the Lord's brothers strictly. However, compare Ps 69:8, "I am an alien to my mother's children." In Joh 7:3, 5, the "brethren" who believed not in Him may mean His near relations, not including the two of His brethren, that is, relatives (James and Jude) who were among the Twelve apostles. Ac 1:14, "His brethren," refer to Simon and Joses, and others (Mt 13:55) of His kinsmen, who were not apostles. It is not likely there would be two pairs of brothers named alike, of such eminence as James and Jude; the likelihood is that the apostles James and Jude are also the writers of the Epistles, and the brethren of Jesus. James and Joses were sons of Alpheus and Mary, sister of the Virgin Mary.
