Yay for reductionism. Adam and Eve being an allegory for obedience has nothing to do with its ability to be used as a foundation for the theological doctrine of original sin. It's a bit like saying that a car can't be used to carry birthday balloons because it is used to carry people the rest of the time. It has, magically, or rather like many other things in the universe, the ability to serve many purposes at once. I do however, tend to forsake the supernatural aspects of religion in these discussions. It's very easy to walk into a religious debate and go "You know you guys aren't really drinking the blood of a 2000 year old religious icon right?" and completely sideline any sort of real anthropological dissection of religious texts.
Yay for assumptions. I was genuinely curious, I wasn't trying to play a smug holier than thou atheist. I was curious as to how say a Catholic priest or official may answer this question; I wasn't trying to bring up a point for the sake of feeling superior in my beliefs. Sorry, I suppose.
I'm not really sure. It really depends on the priest or official you're asking. Their abilities to reason, and the depth with which they have chosen to study or interpret any given text or theological doctrine varies just as much as anything I suppose. Sorry for the assumption, it is the internet, and I know how godless all you heathens are. (I'm an atheist though, not that it matters. Tone is hard in text.)
