I read The DaVinci Code fairly early on, before there was much of an uproar. I enjoyed the read and didn't perceive it as an attack on Christianity because IT IS FICTION.
When I did start hearing about some churches and christians taking offense, I was a bit surprised because, after all, IT IS FICTION. The DaVinci Code is available in the library under the Fiction category. The writer wrote it as a piece of fiction. Therefore, what he claimed or didn't wasn't a big concern for me because, as I've noted, IT IS FICTION!
I finally went to see the movie last night and it occurred to me that there's another reason why I wasn't bothered by The DaVinci Code.
There's nothing wrong with it from a Christian point of view!
Even if every word in The DaVinci Code were true [SPOILER ALERT IF YOU HAVE MANAGED NOT TO KNOW ANYTHING ABOUT THE CONTROVERSY YET!] and Jesus did marry Mary Magdalene and fathered a child, there's nothing unbiblical or un-Christian in the thought. Yes, it's extrabiblical. Yes, it is against our understanding of Jesus as a single man. But if it were true, there's nothing in the notion that should hurt anyone's faith.
Gospel writer John himself tells us, "There are many other things that Jesus did, so many in fact that if they were all written out, I do not suppose that the world itself would hold the books that would have to be written." It could be entirely possible that this story could be one of those unwritten stories and it would do nothing - NOTHING - to invalidate the Gospel as we know it.
What such a story does is challenge our traditions, and for those with a huge investment in the traditions of the church, I suppose this story is a bit threatening. But there is nothing in this story - which, by the way IS FICTION - that ought to worry anyone's little head a single bit.
Sleep soundly church. If you're having nightmares, I'd suggest it might be a chance for you to evaluate your dependencies upon traditions, as opposed to what is actually contained within the Bible.
