We seem to have picked up comments from an author (Carl Olson) at Ignatius Press. Since I happen to be the happy owner of several of their volumes (despite my continuing status as an evangelical "separated brethren" type), I'm going to make it easy for those interested in reading further about the controversy over The Da Vinci Code by clicking here.
I haven't read Dan Brown's blockbuster and probably won't. I'm in the camp that thinks we're looking at a marketing sensation because the central thesis of the book has not been a recognized serious controversy in the scholarship as far as I know. If someone knows otherwise, please feel free to lay it out in comments to this thread.
