I had a feeling I should have put a disclaimer of some sort in my original post. It wasn't my intention to raise the ire of those who still strongly believe Christianity is the one and only Truth.
The only point I meant to bring across is that sometimes people can believe so strongly in something that even if they were presented with facts that prove otherwise it would not turn their minds or hearts away from that belief. It doesn't apply only to Christianity, but to other religions, science, politics, whatever. I mean, once upon a time people were convinced the world was flat and the sun revolved around the earth, and it was the death penalty to believe otherwise.
People are fallible and I prefer to take anything with a grain of salt. I haven't adopted Holy Blood, Holy Grail as the new truth for me, I'm just finding it interesting, and the point Perry made coincided with something I'd been mulling over, not just from reading the book, but for awhile it's a thought in the back of my mind, just how gullible is the human race, and how do we know that what we believe as truth really is truth.
There's some things that can't be denied as 'this is the way it is, you can't change it', but there are other things, esp. stuff that is intangible, that must be believed with a degree of faith, and those things are what I feel I can't accept 100% as truth, but must always be ready to admit the possiblity that they are incorrect.
That was my point, so please, I'm not trying to debate the truth or lie of Christianity, or the believeablity/sensationalism of Holy Blood Holy Grail.
