I have some protestant friends who object to Mary being sinless. The usual root I try is that it was fitting and her being named full of grace by Gabriel and how being full of sanctifying grace at least implies her sinlessness. If you’re full of this grace I dont see how there can be any room for sin. I dont mind if anyone wants to help me fine tune this. I am sure it is gaping with holes.
Now, to the thought i recently had and the purpose of this post. Nothing unclean can enter heaven, right? I thought about how God entered the womb of the virgin Mary, wouldn’t this also mean heaven entered her? Not sure if this is accurate. So when a protestant asks, why did Mary have to be sinless? How about the fact that heaven entered her womb, and if nothing unclean can enter it, wouldn’t the same go for heaven entering her? This could be way off, I apologize ahead of time if I am.
God Bless you all!
