As Elaine Pagels mentions repeatedly in her book “The Gnostic Gospels,” Chrsitianity has itself undergone natural selection. Originally there were many, many schools of thought about the nature of Jesus (man? a god? God? a “special creation” per the Arian heresey?), God, and the church itself. But the Catholic Church became dominent because it was organized into a militarily hierarchy and it monopolized spiritual power. Thus the Gnostic churchs, which allowed their members to have there own spiritual revelations from God and were loosely organized, were easily crushed. The church became a tool of statecraft for the ailing Roman empire to prop itself up with (the cynical Constantine did not close the Pagan temples, and even offered sacrifices on a number of occations).
This is why Christianity is the most widespread religeous meme in the world. In the first few centuries of its existance it sharpened its teeth on all the varient views of Christ floating around the ancient Mediterranean.
(PS the tragedy of the whole thang is that we will never know the real story of Jesus, who I believe tried to remove Roman oppression by fulfilling the prophecies of the Suffering Servant, etc. As a Jew, he sure didn’t claim he was God’s son, and prolly just said he was “ben Elohim,” “of the most high,” meaning sent by God, not to be taken as meaning “son of God.”
I believe Moses said the same thing, but I hain’t mastered Hebrew yet this week, so don’t quote me.)
