In the Roman Catholic understanding, it seems that Mary, who according to Roman doctrine had been exempted from the guilt of original sin [the Orthodox do not accept that humans share the guilt of the first sin but, rather, only the consequences] before all eternity, and thus could not have sinned.

It may "seem" that way, but, to the best of my knowledge, that's not what we believe.

It's probably best not to create strawmen by drawing assumptions about what others' doctrine "seems" to say. Better to deal with what they actually do say.

I posted from the OCA site only to articulate what the Orthodox DO beleive, not so much what the Catholics do or don't.
