Bogo,
I do not say that there are only a few thousand Orthodox left. Having said that, it is not impossible to believe a possibility. Even Fr. Georges Florovsky spoke of the Church being a "little flock" in the end time, when it would be difficult to find any Orthodox Christians. I do not believe it is really helpful to keep saying "Look what ROAC believe, how unbelievable". If we read the Bible and Fathers, I think the idea of a remnant of a few thousand in the end times is perfectly believable (though perhaps not the only tenable position). The question really is, if indeed this is the opinion of Bp. Gregory and ROAC in America, then are they right and is this just such a time when almost the entire Church has fallen away? What's the difference regarding numbers, anyway? God saved but a few thousand in ancient Israel at one point, and that was after he had helped form an entire nation that was to be devoted to him. Only a few thousand? it's happened before in Christian history. Perhaps someday some ecclesiastical writer will write the words: "one day the Orthodox world woke up and found itself ecumenist".
