The Official Web Site of Bestselling Author Dan Brown:

"Much of the positive response I get from within organized religion comes from nuns (who write to thank me for pointing out that they have sacrificed their entire lives to the Church and are still considered 'unfit' to serve behind the altar)."

Yes, they are unfit, just like ricecakes are unfit for confecting the Eucharist. That's not a value judgement.

"I have also heard from hundreds of enthusiastic priests. While many of them disagree with some of the ideas in the novel..."

I should hope so!

"...they are thrilled that their parishioners are eager to discuss religion."

Discussing religion isn't enough, you need to have faith. Discussion is empty if it doesn't move towards truth and righteousness. (Perhaps this is part of the problem with "Sustained Dialogue", talking isn't enough, you need to learn.)

"Father John Sewell of St. John's Episcopal Church in Memphis stated it particularly eloquently in the press recently, saying: 'This [novel] is not a threat. This is an opportunity. We are called to creatively engage the culture and this is what I want to do. I think Dan Brown has done me a favor. He's letting me talk about things that matter.'"

Unfortunately, "Fr." Sewell isn't a priest of course.
