James, the brother of Jesus

James is one of Jesus’ half-brothers who became a prominent figure in the early New Testament church. Scripture tells us that James was not originally a believer in Jesus (see Mark 3:21; John 7:5), but following Jesus’ resurrection became a pillar of the church in Jerusalem (Acts 12:17; 15; Galatians 1:18-20). He is most likely the author of the epistle of James due to the timing of the epistle and his prominence in the church at that time.
