Nearly Finished Adam, Eve, and the Serpent

I have just the three-page epilogue left to read in this book.  It is basically a history of Christian thought/ opinion/ dogma about this story from Christ through Augustine (about 500 AD.)  I find the seriousness which this obviously ludicrous myth is debated amazing, but completely astounding is that the interpretation  Augustine came up with became the one the religion went with.  Over the 500 years, almost every interpretation imaginable was offered by learned theologists, some of which were very reasonable.  But it was Augustine who came up with the idea of original sin and the fact that neither death nor sex are natural, but are punishments for Adam's sin.
