‘In that Adam sinned and sin passed to all men’ ... if there were humankind who had no spirit component (perhaps they evolved to that point of homo erectus but without a spirit in their soul/behavior mechanism) and God created adam to have a spirit component but it was sinless until he willfully disobeyed God, then all those descended from Adam would have inherited the spirit component as passed to Adam’s off spring after God breathed into Adam and he became a living soul ... Or something like that?
Clearly my mother OD’d on Aristotle when she was carrying me.

I was not thinking of “efficient” cause, of how sin is transmitted.
I was thinking more of what man (and man’s nature) is. The best I can do is that man was not made a sinner, but since the Fall we have not seen man in his uncorrupted nature. It’s a kind of counter-empirical view. We see men, but the true nature of man, which we never see embodied anymore, is not what we see. We see men who are defective.
If the space critters from the planet No’rf infected us with a virus which corrupted the genome so that, ever after humans were born with one leg two inches longer than the other, every man we say would limp, but the limp would not be ‘natural’ to man. Sort of kind of a little maybe like that.
