I read the book. Im open minded.
Keep in mind, that Dan Brown collected historical fact and myth and rumours and created a fictional story around that information.
If you don't want to read it because you believe a FICTIONAL book might be blasphameous, then you are missing out on one of the best books you may ever read.
Dan Brown didn't claim his work was any gospel. He based it on the long thought possibility of The Holy Grail. Do a search on google for it. There are lots of books out there that have facts and rumour/speculation about the subject.
The Holy Grail is believed to be literally the Blood Line of Jesus Christ. That Jesus and Mary were married and had a child, possibly two. That the people in power at the time were highly afraid that the offspring of their union would be entitled to being a King. Without cracking open the book right now or research, I don't rememeber where.
The children where then hidden from the Roman Catholic Church by a secret society that exists to this day, The Priory Of Sion.

The Roman Catholic church couldnt afford for evidence of this to come to the light of day, as it would destroy its power, which its enjoyed now for centuries.
Perhaps you should research Roman Catholism and its history. I was RC until 15. Confession was used in the time even AFTER Jesus as a way to gather information on crimes going on in the city. There has been no need for a Christian to go to confession since Jesus died and cut out the middle man for us.
Anyway, The Priory of Sion has supposely hidden this evidence, tho what, I don't remember.
In the end, its a very intriquing story. It discusses how the bible itself came about, or the stories published rather than all the gospels that were actually submitted. Its a well written, exciting story that will make you think about various facts you may have never read about or discussed before.
Keep in mind, even IF this story were true and evidence came about that could prove it 100%, what difference did it really make? None.
You still live the life of a Christian or should or don't if you didnt already. You still follow gospel. Nothing really changes, you aren't granted some new right to sin.
Personally, I dont follow anyone blindly. Im not in the military and I think for myself. I don't believe that Jesus was married to Mary, mostly because of lack of evidence. Whether or not I dis-believe the Holy Grail Bloodline story, doesnt make it any less false or true. Just like if you believe in Jesus. Whether or not you believe doesnt change the fact of the matter that Jesus came and died and is God.
Personally, I think it sparked more interest in old religion. Personally, I'd like to learn old Hebrew and read over the red sea scrolls myself and interpret the original script for myself. There are lots of things I'd like to research and learn about now, because its actually interesting, especially after reading something that makes you think.
