Michael, I admit I do not have an answer, but I am sure some of the more intellegent here will be able to help you. I am a fairly simply person. I am glad that you were able to be more specific in your concern though, as I said, I am confident that someone will be able to help you.
For me, there isn't a doubt in my mind that the Holy Orthodox Church is the Church of Christ, the Church spoken of in the Holy Scriptures, and so such questions do not disturb me, even if I don't have an answer to them. But for you, who are still inquiring into the Church of Christ, I can see how these issues could be very important. Forgive me if I have minimized the anxiety that these sorts of questions cause you, but I still implore you (and myself) to be humble when we approach Christ and His Holy Church.
P.S. I am not a priest or a monk. I assume you mistook me for one based upon my profile picture. That is a photograph of holy Elder Paisios of Mount Athos. Forgive me.
