Here's where we go when we take the stories as Metaphor.
Adam and Eve and the Fall
If Genesis is just a story, then so is the divinity of Jesus, and the magic stuff that supposedly happened on the cross. That at best neuters Christianity. At worst, it makes it irrelevant.
Adam and Eve and the Fall
- Didn't really happen. We are evolved animals, and never were or could be perfect. Our intelligence lets us be moral creatures, however, with the capacity for both good and evil.
- Didn't really happen. The OT people thought of their God as the cause of all things, good and bad, and they created stories to justify in their minds how bad events were really punishment.
- Didn't really happen. The idea that he "told" someone to kill his son is evidence of mental illness, not righteousness. God didn't actively protect Abraham's descendants above other tribes in the world.
- God didn't actually make a half-divine half-human baby (like the Greek gods of myth). Jesus isn't God (if Jesus existed as described at all). Jesus just had better insight into God than others.
- There was no original sin, though it is clear we aren't perfect. Substitution blood magic makes no sense. Belief isn't a magic spell that saves. The story of Jesus' death is just a way of grabbing out attention so that we'll be as good as Jesus was. Jesus was just showing a way to heaven for good people.
