Peter the Roman.

Since the days of the crucifixion two entities have been hiding the truth from mankind. The Roman Catholic Church and the Priory of Sion, both entities have their own goal and reason to hide the truth. The Roman Catholic Church wants the truth hidden or destroyed, because it tarnishes all that they believe in. Jesus is the son of God and there for divine, there is no way that they can accept that Jesus was married to a fallen woman and that together they had a child. The Priory of Sion wants the truth hidden, because mankind is not ready to accept the fact that Jesus was married to Mary Magdalene and that together they had a child and that their bloodline is still walking the earth to date.
