Um…you need a little context in your question. Do you mean the “DaVinci Code” is the distorted book or the “DaVinci Hoax”?
If you mean the former, yes, it is distorted in the extreme and Dan Brown’s so-called “resources” have been discredited by Athiest, Protestant, and Catholic scholars alike. He has an adjenda which he stated very publicly…for people to question the very roots of what they believe. His goal was to cause questions where there were none before.
It is a book full of lies sold as truth. His sources are questionable…he cites “the Louvere” but never names anyone who assisted in his so-called “research”. He very likely was there to look at the paintings, however some locations in which he allegedly visited are geographically incorrect in his book. There were many many issues with his poorly written book.
Regarding the latter, “The DaVinci Hoax”, it was well researched, refuted the issues in Dan Brown’s book and candidly discussed several topics. It was difficult to get through in some places, but it was very informative and a good outline of part of Church history.
Hope that helps!
