But I thought the point of the Immaculate Conception was that Christ would not be born to a sinner?
If you want to grasp my point of post #90 ,it’s that original sin is paternal sin inherited,thus an infant fetus is not in a state of total depravity due to actual sin that freely committed by an act of individual will of a fetus.
This is another reason why Calvin is sickening when he says there are babies are in hell.
In the case of the Blessed Mother original sin was removed by a singular act of Grace by God so there is no original sin joining flesh with our perfect Lord Jesus,thus he was in a perfect vessel by the Grace of God
