Did Jesus have any brothers? Hmmm.....I know: what do the Scriptures say?
(1) Mark 6:3 - Is not this the carpenter, the son of Mary, the brother of James, and Joses, and of Juda, and Simon? and are not his sisters here with us? And they were offended at him.
(2) Matthew 13:55-56 - Is not this the carpenter's son? is not his mother called Mary? and his brethren, James, and Joses, and Simon, and Judas? And his sisters, are they not all with us? Whence then hath this man all these things?
(3) Mark 3:31-32 - There came then his brethren and his mother, and, standing without, sent unto him, calling him. And the multitude sat about him, and they said unto him, Behold, thy mother and thy brethren without seek for thee.
(4) Galatians 1:19 - But other of the apostles saw I none, save James the Lord's brother.
*re-reads the scripture verses above* Now, I will readily admit to not being the sharpest tool in the Christian toolshed, but a cursory reading of the verses above should answer the question at hand: to wit, yes, Jesus of Nazareth, our Lord & Saviour, did indeed have several brothers.
