A theology book loaned by a friend, prompted by a conversation about evil. I found the first third of the book finely diced arguments with a whiff of the "dancing on the head of a pin" to it, but stuck with it and found the argument about the nature of sin and original sin very persuasive even without a belief in god as a foundation. The more theology I read, the more intertwined I believe most of the fundamental concepts to be. All are attempts to explain human nature and behavior, the world around us, and the heavens.
One of her central arguments is that sin is not against god, but against creation. (That was the finely diced part.) Original sin is faultless until we reach an age where we are able to choose: sin or not sin. We feel guilt because we can't escape the fact that humans are part of systems (that's the relational part) and many of those systems sin by harming creation. It's unrealistic to believe one can divorce oneself from the rest of humanity. This feels like it could eventually connect with a lot of Buddhist discussion of suffering and its inescapable nature. To be is to suffer. The semantics are different but it feels like the same discussion to me.
I'm no theologian and unwilling to summarize this further, to defend it, or to pick it apart. I found it to be an interesting premise, and it allowed me to see concepts such as sin and guilt apart from how organized religion uses them to bludgeon people.
