Please excuse my nitpicking, but GOC stands for Genuine Orthodox Christians, does it not? I don't think it stands for "Greek Orthodox Church".
I feel it would be more precise to speak of the Orthodox Church in Greece, rather than the "Greek Orthodox Church".
The Church of God is neither Greek nor Russian, Romanian nor Serbian, Palestinian nor African, etc., but is Catholic.
It is one thing to say the "churches of Greece"; another to say the "Greek Orthodox Church".
Naturally, my objection would extend to usage of ROC (Russian Orthodox Church).
I believe it is more precise to say, "the Orthodox Church in Russia."
I'm sure many holy people have used both forms, so I suppose this is falls under the realm of my personal opinion.
Any thoughts would be appreciated.
