Corruption can be a relative thing? Sin is sin, RobbyS. And it came from Adam. And all humanity is begotten of Adam in his own likeness. How do you go about measuring sin? ANd how far is “too far”??

[Campion]

We don't believe in a "sin nature" handed down from Adam, smvoice. Adam's sin rendered him (and Eve) unable to communicate sanctifying grace to their descendants through the natural process of generation. It also took away some gifts which are called "preternatural gifts" ... freedom from concupiscence (= attachment or fondness for sin), strength of will and intellect against sin, impassibility (freedom from suffering), bodily immortality, etc.

All of these things were things Adam should have been able to give to his children merely by begetting them. Their absence is what original sin consists of, not any objectively real "sin nature".
