You are skipping steps.Maybe.
But if they're never born...?
i.e. Is the burden of original sin applied at conception or at birth?
I don't actually know.
I think the sin is transferred during sex, or else children born of C-section never inherit the curse of the orignial sin.
So I guess the devil has fried baby fingers and toes at his eternal Bar-B-que!
Just to clarify:
At birth would be the child's first breath, and a c-section newborn along with a natural birth newborn both take their first breath when they are born.... so, if original sin is passed on to the baby at birth, then c-section children would also receive it at that time.
So if they're aborted before that... fast track into heaven, no?
