"And finally why does he say that Jesus had 6 half brothers and sisters? When the bible contradicts that claim."
I do not recall that the bible gives a number, but it does confirm that he had brothers. It mentions them as coming out when he is preaching to collect him. When told that his mother and brothers were looking for him, he replies "Who are my brothers and mothers? Those that do the will of God" Traditionally the brothers were considered elder half brothers by a previous marriage of Joseph.
I am one who buy into the tradition that Joseph had children from a previous marriage, asthe bible doesn't tell us this, but I don't normally make it a point of division either, BUT....
You state that these older brothers were half brothers (according to tradition). How can they be older half brothers? If these brothers are from a previous marriage of Joseph, the only way they could have a blood relationship with Jesus would be for Joseph to be the biological father of Jesus (Thus dening the divinity of Christ).
I take it you meant that these were step brothers, not biological half brothers.... Also, scripture tells us that Jesus had not just brothers, but also sisters:
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?
