Ah, if you're Orthodox that would explain your puzzlement at my statements. In fact I was going to say that you sounded more Orthodox in your view who do not believe in original sin. Consequently it would have been possible for Mary to have lived a perfect life. While I reject this notion as it still runs counter to scripture, I believe the Orthodox view is a cleaner approach than the Catholic's Immaculate Conception dogma, which to me makes no sense at all if one believes in original sin.
It makes perfect sense, but not if you define "original sin" the way Protestants do.
