That makes me wonder how much was added to the Bible and New Testament during those many dark-age days preceding Guttenberg's printing press, when Catholic monks were accumulating contents for, translating and hand-writing what finally made it into modern Bibles.
The fact that the Devil and a Heaven distinct from Hades were not in Homer's Odyssey leads me to think that those theological touchs were added by monks.
No need to wonder. Archeology has proven that the bible we have to day is substantially unchanged. Differences are minor (e.g. the dropping of an article), but the information is unchanged.
