Staying on a pretty broad level, I wonder if corporate sin is another category that is helpful? Our "membership" in a certain community would then implicate us in some real way, whether or not we had a functional role in creating it. I also wonder, on similar lines, if functional could be split up into acts of intellect and acts of will (this is probably not the best way to put it). Acts of intellect could be cultural sin that influences our vision of life, and acts of will could be seen as specific actions of functional sin. That is probably not a helpful way to delineate those, but something like that might be good.

I also wonder about the "ontological" category, and its implications concerning evil. Giving sin substance could push hard against the tradition which has wanted to avoid giving sin this much credit, as it were, and only explicating sin/evil in negative terms (e.g. privation).

Anyway, just some thoughts.
