If I had oodles of cash again, I'd probably offer rewards for intelligent critiques of Gnosticism, things Gnostic, and above all things called "Gnostic."
After months of searching for anything worth reading in the arena of orthodox responses to the DaVinci Code, I finally found one. Which is not to say that it is endorsable by any stretch, only unique in the field. He seems to be the first in the orthodox camp to figure out that the DaVinci Code is not actually Gnostic, though it seems to be because he thinks we don't exist. In any case, since the major impetus of the DaVinci Code is a Shadow Play with Roman Catholicism, I found it interesting.
