A Bible conspiracy theory is any conspiracy theory that posits that much of what is known about the Bible is a deception created to suppress some secret, ancient truth. Some of these theories claim that Jesus really had a wife and children, or that a group such as the Priory of Sion has secret information about the true descendants of Jesus; some claim that there was a secret movement to censor books that truly belonged in the Bible, etc.
This subject should not be confused with deliberately fictional Bible conspiracy theories. A number of bestselling modern novels, the most popular of which was The Da Vinci Code , have incorporated elements of Bible conspiracy theories to flesh out their storylines, rather than to push these theories as actual suggestions.
In the book The Christ Conspiracy, The Greatest Story Ever Sold, Jesus and Christianity were created by members of various secret societies, mystery schools and religions to unify the Roman Empire under one state religion, and that these people drew on numerous myths and rituals which existed previously and then constructed them into Christianity that exists today.
In Channeling of Spiritualism, Silver Birch claimed conspiracy above.
