Brown can believe whatever he wishes, I have no problem with that. But his beliefs are no more credible as a Holocaust denier, and he should be exposed for that. Brown's beliefs are based on hatred towards Christianity, not on facts. There is nothing credible about any of the stuff Brown passes off as facts.
I don't disagree with you at all on that. I would be less than honest if I did not confess that much of what I believe is incredible too-- Jesus' virgin birth, His miracles, walking on water, His resurrection, etc. etc. (Thanks be to God).
I have not read the book and probably won't see the movie, but my wife has read the book. We were discussing this claim about Jesus having married and having children. To me this would not, if true, detract from His divinity in the least, and would frankly go even further in showing His fully human side. Part of being human is knowing the joys, frustrations and sorrows of marriage and parenthood. I believe the scriptures say, "He was in every way tempted as we are, yet without sin." I am no Bible scholar (but I am trying), but at least some of the assertions made in the Code, if they were true, would not shatter my faith. That is not to say that I believe them, only that I strive for my faith to be deeper than that, deeper even than disagreements about the "proper" content of the Bible and its authority.
