Anastasios,
It has always, well maybe not always, been my belief that if there are enough converts: english speakers, or Russians, or Mexicans, and if God finds them worthy then everything else will happen naturally. Those people will find their place - they will become the priests, the council members, ect. and they will bring with them their language and culture.
I was at one time in the OCA and it had a distinct Russian flavor. Therefore I also believe from experience that it is easy to have a quiet resentment when Mother Russia or Hellenism is thrown in your face as if it were the superconducting core of the faith. I now see that people find solidity when they think their heritage is being preserved or perpetuated in this "melting-pot" of a society. This is perhaps a weakness or a strength - depending on how you look at it, but either way, there is something for everyone to gain from it; Looking back, I now see I gained something intangible from the Russians.
As far as Paisios goes and besides what it says about him, this is a common example of taking it to far. But when the a persons spirituality is weak or dead, you can often see that culture fills the void and becomes the religion. This must be seen for what it is, it is a spiritual sickness like any other. At least thats what I think.
