Query: Simply Terrible

Like many others, I read the Da Vinci Code and this notion sparked my curiosity. I researched online and found that Holy Blood, Holy Grail was the book that fully illustrated this theory.I read it and wanted to burn it. The three people who wrote it are not historians. They enjoy molding conclusions out of evidence that is completely bogus. It is almost as if their theory was the dragon created by seeing the shape in the clouds. They mold the "evidence" to fit their desired beliefs.It was a terrible book. The research was poorly done and poorly presented. I discussed it with an history professor at a private university and he described the authors as "hacks." I do not want to pass judgment on the authors personally, but this material they published is pure garbage.I am not a Christian and am quite unbiased as far as the teachings of the Church are concerned.
