The Da Vinci Code’s entire claim is based on the fact that just maybe, the bible today isnt what it was at the time of Christ. Given that, quoting the bible as evidence against DVC says nothing in itself.
You see, when people come up to you and say say for example, that the bible is a load of BS and that God doesnt exist, you dont say “Aha! But look here, in the bible it says that God exists! What do you have to say to that?”
See my point?
