There is already a theory behind the Da Vinci Code.
I think it's a possibility.
Know how the Bible consists of different Books written by different people? Well, those books didn't appear all at once. As the years went by, they would find certain writings and the Vatican or the Pope would review them before approving them to be added to the Bible.
Years ago, someone found some writings that mentions Jesus having a wife. She was even considered a disciple. However, being a male-dominant religion... the Pope refused to approve those writings into the Bible and decided to call Mary Magadeline a whore. So, there could be many Books out there that haven't been added to the Bible... just because the Pope doesn't want them added.
The truth is out there!
