Remember the Da Vinci Code?
Here is a far-from-Christian New Testament scholar, Bart Ehrman, pointing out all of that novel’s historical inaccuracies.
Ehrman is not committed to the infallibility or authority of scripture, nor to the accuracy of the New Testament Gospels as to the life of Jesus. He denies the divinity and resurrection of Jesus. By no means a Christian, but he is concerned to point out that the Da Vinci Code makes many historical claims that are just plain wrong.
