Back to argument: if Mary did not have a nature like ours, i.e., one that had been corrupted, then are you not saying that Jesus could not have a nature like ours? My understanding is that the corruption is not in our nature but that our nature has been bent or twisted - it is the same thing as it was before the fall, only now it has been damaged, as if termites have been at a piece of wood, and what is left is still wood, only weak. If you say the corruption is in the essence of man, then you are doing big damage to the incarnation, are you not? Aren’t you saying Jesus became some sort of man with a nature different from ours?
I’ve heard ‘the saving from falling’ idea before - I find it speculative and circular in reasoning. We think she was sinless because she was, is what it seems to amount to. What I am interested is in the idea that in order for Mary to be saved at all she had to first be proclaimed a sinner - even if she never sinned. I am puzzled as to why this does damage to ‘original sin’ - I find the Orthodox conceptualization more appealing, frankly, than the Catholic, although as a Westerner I inherit Western conceptualizations of theology and in that sense (this will make PR happy) am a daughter of the Catholic Church more than that of the East.
I’m back to C.S.Lewis’ point about discussions about Mary. To further it, if a man tells me his mother is the most beautiful woman in the world, I am not inclined to argue with him but rather to be happy that he loves her. These sentiments. I think, get in the way of honestly appraising how we should look at Mary. Augustine said something along the lines about how it was inappropriate to discuss whether she actually sinned, and this situation seems to be handing the whole field to the side that will stop at no excess in regard to praising Mary. My 2 cents.
