Quote: Whoever wrote the stories, the order in which they were written shows a developing theology.
We know this stuff was edited, though, to account for changes in church doctrine. I maintain that when they were written is far less important than when the last redactor sat down with his blue pencil and started making changes.
As late as the Codex Vaticanus, the oldest, more-or-less complete xtian bible c 350 AD we find significant differences between it and "modern" bibles. That did not happen by accident, my friend.
