I also question the topic ?
How could you save most souls ? If you do orthodoxy as something nationalistic or cultural you will have alot of quantity , but if you do it as god religon you will have quality, what do you prefer ?
I prefer quality, but from quantity you can find quality , I think , suppose , maybe it is like that, I don't now u tell me what do you thiink quality or quantity, how can you get it both ? I had put alot of thougts on it
Secondly I belive that all orthodox shoulds try to learn Koine , (old greek dialect on wich the spoke in the byzzantine empire).
I belive that it is something special with that language and that's way God chooce it.
