Hold yer fire there, Hoss! If you have a problem, take it up with Matthew, Mark, Luke and John. Oh, and Paul, too.
Jesus’ Brothers, Sisters & Mother
Jesus’ siblings are mentioned as accompanying Jesus and his mother to Capernaum after the marriage at Cana (John 2:12). Later Mary and these brothers are recorded as seeking an audience with Jesus (Matthew 12:46-50; Mark 3:31-35; Luke 8:19-21). Toward the end of Jesus’ ministry, His brethren are mentioned as urging Jesus to prove His Messiahship, which they themselves doubted (John 7:3-5). That they were later converted is clear, for they are described in Acts as uniting with the disciples and others in “prayer and supplication” prior to Pentecost (Acts 1:13-14). Paul implies that they were all married (1 Corinthians 9:5).
Many commentators hold that the author of the epistle of Jude, who identifies himself as the “brother of James,” was one of these brothers (Jude 1). It is also generally believed that the leader of the church at Jerusalem was James the brother of Jesus, (see Acts 12:17; 15:13). This seems to be confirmed by Paul’s reference to his visit to Jerusalem, in which he states that he saw only Peter, and “James, the Lord’s brother” (Galatians 1:18-19).
Christ is also quoted as asking:
“Who are my brothers, sisters and mother?”
I’m not too interested in “many commentators”.
