It's Dan Brown, Stupid!

A great resource, a must have for every single parish:
Mark Shea in an interview with Zenit:

"Once you understand Brown's game, you start to realize that it is Brown -- not the Catholic faith -- that is taking people for a ride. "

Q: What compelled the writing of this book?

The longer answer is that "The Da Vinci Code" has become the source for what I call "pseudo-knowledge" about the Christian faith.Pseudo-knowledge is that stuff everybody knows," such as the "fact" that Humphrey Bogart said "Play it again, Sam" -- except he didn't. Pseudo-knowledge doesn't matter much when the issue is the script of "Casablanca."

It matters greatly when it adversely affects the most sacred beliefs of a billion people, and when it levels the charge that the Catholic Church is essentially a vast "Murder Incorporated" network founded on maintaining the lie of Jesus' divinity and resurrection...Those who say, "It's just a story," simply do not understand that this deception is part of the book's power. People often receive through fiction what they would be on guard against in reasoned debate.

And in true Mark Shea humor: " The best cure for "The Da Vinci Code" is, in the end, hearty gales of well-informed laughter"
