I've read the book before it was planned of turning it into a movie.It was a fiction alright but interestingly, if you read the "FACT" page, you will agree that the novel can claim historical facts because the documents, rituals, organization, artwork and architecture that were presented all EXIST.The "FACT" page, however, did not refer or made no statement whatsoever about any of the ancient theories discussed by the fictional characters so it is up to the readers to interpret those ideas.

I don't believe that Jesus Christ ever married before he was crucified bit I believe on the facts that negate what Catholics and other Christian denominations believe regarding His divinity.

Dan Brown made mentioned of the council of Nicaea in AD 325 which made history as the first ecumenical or worldwide conference of the bishops and/or church leaders in the Christian world. The purpose of the council was to resolve the disagreements in the church of Alexandria over the nature of Jesus Christ whether He was of the same or similar substance as God and Father. It was in this council that the belief in Jesus Christ as God was made an official doctrine, meaning that before the fourth century, there is only one belief that the Father is the ONLY true God and that Jesus Christ was never a God.
