“...then we must believe that God has done a supernatural act in that person who has been regenerated.”
Orthodoxy would say that God has “done a supernatural act” for all persons, equally; indeed Orthodoxy would say for all of Creation, Padre.
“On the one hand, we have the Christian. This month the Christian is “saved.” Next month he’s lost. The following month, he’s saved again. The next month or 2, he’s lost. Then he’s saved again. It’s a crap shoot all the way to his demise.”
The Western reformed/protestant concepts of “salvation” and that of the Orthodox East are different, Padre. We don’t see any “saved/not saved” paradigm because for us theosis is both a process and an end. You are dealing with a problem we simply don’t believe exists, rather like that of Pelagianism which caused such a stir in the West and barely a ripple in the East. Our basic beliefs about our created purpose and maybe even more about the nature of man as opposed to his condition a) since the Fall and b) since the Incarnation mean that discussions like the one we are having here are, nowadays anyway, necessarily destined to go nowhere.
are you telling me there is no salvation in the orthodox church?
