Just a side note, the intensity of feelings that this seemingly innocuous question evokes, points to one of our uniquely"diaspora" problems. There are so many opinions, traditions, customs etc.. which in the big picture may be relatively trivial but a unified Orthodox administrative body not respecting them (within reason) is bound to fail.
As many of you know our ACROD has recently elected a non Slav of Greek American background as Bishop. He is marvelous and is quickly being accepted as he travels the Diocese and gets to know us. Last Sunday,I was in suburban Philadelphia where Bishop Gregory was hosting a Lenten Retreat. He made a comment really on point. Speaking to the obviousness of his Hellenic heritage he mentioned that he had heard some choral arrangements that day for the first time and every parish he wen to, he was learning "our ways." He laughed and said that for five years he was the itinerant preacher and confessor in GOAA' s Metropolis of Atlanta. He visited 60 of the 71 widely scattered parishes and he learned something important. He assumed for the first 50 years of his life that the way things were done at home, or at seminary were the Greek way. His travels opened his eyes to the understanding that while there was general "way" of doing things, it varied by where the pastor grew up, what part of Greece the parish founders came from, what was the demographic composition of the parish and so on. Even two parishes in the same city under the same bishop were not identical.
Anyway, his observations seemed relevant to this discussion.
