A while ago, I asked the question Do any denominations teach that Adam and Eve had children in the Garden of Eden?, of the back of another question. Perhaps unsurprisingly, it hasn't gained any answer, so I did some research to see if I could answer it myself.
I came across a reference that does explicitly state that Adam and Eve had children in the Garden of Eden. The Urantian Book appears to be a modern 're-write' of the story of the Bible, which according to its wikipedia page "claim to be a clarification and expansion of Christian belief".
Personally this is something I would very strongly oppose - the Bible is the only way we can know God. However, reference to it would answer the question. If we accept traditions that use other source (e.g. the Book of Mormon), would it be appriopriate to write an answer referencing this Urantia Book?
