Rather interesting item. It specifically extols the one god and could apply to a newly christian community. In practice this whole mass of materiel makes no mention of serious secondary Gods and suggests that Monotheism was central to Egyptian thought as well.
Certainly the Hebrew Bible says as much and this is likely source material to that. This material also does carry information from before the Pleistocene Nonconformity when an understanding of GOD would match mine. This is no Greek or Norse Mythos at all.
I would like to see an open scholarly debate on all this. I suspect we have gotten a lot wrong in past considerations. Consider the legendary nature of Sumerian docs and Greek docs....
