No. As I understand it, The DaVinci Code is a work of fiction, and this particular piece of fiction did not produce any "thought-changing" effects in me.
However, the Catholic church made a regular practice of shielding known child molesters for many years (if they have indeed stopped it to this very day). Those "acts of facts" forever changed my perception of the Catholic church.
I was blessed (or perhaps cursed) with a questioning mind, and have gone through some major "changes-in-thought" in my adult life. Even though I was raised a Catholic, and have been a Baptist, and a born-again Pentecostal Christian, and some others as well ....
One day I got to thinking about the Biblical passage (one of the foundations of Christianity), "For God so loved the world, that he gave his only begotten Son, that whosoever believeth in him should not perish, but have everlasting life."
Now, John 3:16 may be one of the most well-known quotes from the New Testament, and lots of God-loving Christians use it as a tool to try to convert non-believers into believers. BUT, they neglect to point out the next two verses:
"For God sent not his Son into the world to condemn the world; but that the world through him might be saved. He that believeth on him is not condemned: but he that believeth not is condemned already, because he hath not believed in the name of the only begotten Son of God"
These verses seem to contradict each other. Jesus wasn't sent here to condemn the world, but if you do not believe you are indeed condemned.
Huh?
If you accept Jesus as the Son of God sent here to redeem your sins, you get to go to heaven, and if you don't ... well, you don't.
After much thought, reflection, and soul-searching, I cannot accept such a premise. I cannot believe that a loving God would condemn people to hell and damnation based solely on a single belief.
I don't point this out as an attempt to convince anyone to see it my way, but as way of explaining why some trivial pop culture fiction like The DaVinci Code just doesn't have what it takes to change my thoughts (I'd like to believe that my thought processes aren't that superficial).
