From my understanding, Mary was not charged with original sine because God new that Christ needed a mother. (According to Roman Catholic doctrine.)
If Mary had carried the guilt of “original sin”, then Christ would not have been sinless. If Christ carried original sin as a stain on his soul, he could never have been the perfect sacrifice that atoned for all of our sins.
Other christian faiths have often failed to provide a reasoned explanation of how Christ could be sinless when born of a human mother.
Does my pedestrian expression of the crux of the matter suffice? LOL
... and if Mary's mother had carried the guilt of Original Sin, then Mary would not have been sinless. And if Mary's grandmother had carried the guilt of Original sin, then Mary's mother would not have been sinless.
You'd have to carry this line of reasoning all the way back to a sinless Eve, and we well know Eve was not sinless.
So, we accept scripture, that Jesus Christ was born of a virgin, Mary, who was herself in need of salvation, according to her own words.
Jesus Christ was sinless. Mary was not. Was she favored and even blessed? Yes, scripture tells us this. But it also tells us she was not sinless.
I do not understand the purpose of adding this Mariology as a result. It's not necessary to salvation and it's not supported by scripture.
That's why you see so many rebuking the belief on the FR Religion Forum.
The sin nature comes from the father, not the mother.
The reason that Jesus was born sinless was because he didn't have a human father; God was His father. He inherited His Father's nature.
If Mary was sinless, there would be no reason for Jesus. She could have been sacrificed.
God gave His Son because no man was sinless. ONLY GOD is sinless. To say otherwise, is calling God’s Word a lie. And that’s what satan has done from the beginning. It’s good vs evil with this Mary being born sinless. She was a virgin, that is all that was required. God’s makes the rules and it was prophesied Jesus would be born of a virgin - not someone sinless.
