Christianity is uniquely defined by the bible.
If the foundational stories of the bible are shown to be MYTH, then that means they are not factual.
They becomes Aesop's fables or Grimm's fairy tales.
(The DNA Herding God says to himself: "Hmmmmm, think I'll plant a living spirit in that upright ape over there, but just to keep 'em really guessing I'll make up a story about a garden to pass on down the line." Wonder why He didn't just decide to write, "Decided to plant a living spirit in that upright ape over there.")
Not only is this God an absentee landlord, but he's also a bit capricious.
I'll not be able to respond again until later this evening. See ya. Gotta go to church (since I'm the pastor.....they expect those things...:>)
I am fascinated by the various interpretations of Genesis. For instance, the Jewish commentary (Chumash) says that God looked into the Torah to create the world, that the firmament divides between spiritual and physical, that portions of the Torah (including Genesis 1) cannot be common knowledge and thus is passed down orally from generation to generation among a very few.
Also, the word "myth" has morphed over the years to mean something factually incorrect and also, untrue. But historically, myths were used to convey truth which is 'beyond' simple language - or which survive regardless of language.
The parables for instance are like tiny myths. When Jesus was speaking of the sower and seed or the vineyard owner and the tenants, He was conveying Truth but not facts.
