Galatians 1:19

“But other of the apostles saw I none, etc..] This is observed to show, that as he did not receive the Gospel from Peter, so neither from any of the other apostles, whom he did not so much as see, much less converse with; save James the Lord's brother; not James the son of Zebedee, the brother of John, whom Herod slew with the sword; but James the son of Alphaeus, he who made the speech in the synod at Jerusalem, (<441513>Acts 15:13) was the writer of the epistle which bears his name, and was the brother of Joses, Simon, and Judas, who are called the brethren of Christ, (<401355>Matthew 13:55) and that because they were the kinsmen and relations of Christ according to the flesh, it being…”

“Compare Act 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.

From the Acts of the Apostles, it is clear that there were two of this name in Jerusalem. Of these, James the brother of John was slain by Herod Acts 12:2, and the other continued to reside in Jerusalem, Acts 15:13; Acts 21:13. This latter James was called James the Less Mark 15:40, to distinguish him from the other James, probably because he was the younger. It is probable that this was…”

“But other of the apostles I saw none, save James the brother (that is, the kinsman) of the Lord - Therefore when Barnabas is said to have "brought him into the apostles," Act 9:27, only St. Peter and St James are meant. Galatians 1:24”

“James: Mat 10:3; Mar 3:18; Luk 6:15; Act 1:13, James the son of Alphaeus, Jam 1:1; Jde 1:1 the Lord's: Mat 13:55; Mar 6:3; Co1 9:5 Galatians 1:20”
