[quote="TEPO, post:3, topic:298654"]
But Angels have never experienced Original Sin, because they were never human... When an angel falls from grace, it has nothing to do with concupiscence -it's purely their own creation... Unlike us, who are prone to sin.
Therefore it's not a "genetic" flaw for them, rather it's their creation. For us, it's purely genetic -in other words we didn't create it, we're just burdened with it.
But being both spiritual and physical beings here on earth, we are responsible for both aspects... Our spirits and our flesh actually seem to have a very unique relationship -especially considering that upon the final judgement we must first reunite with our flesh.
The CCC has an answer to this question.
