My plug nickel impression has been that this is a bugaboo and claim made by some Eastern Orthodox (including Bishop Kallistos?!), but that Oriental Orthodox don't give two hoots about the matter. I'm no theologian, this is what I've gleaned from talking with people and reading snippets here and there.I'm gladly open to correction and enlightenment.
That's an interesting perspective Indigo, and I like that term "bugoo". Its been my experience that most of the time Orientals believe they are on the same page with the EO, except when Chalcedon comes up.... When it does the poop can really hit the fan!
But it its quite common for Orientals to say things like "all Orthododx churches are the same" (there isn't much difference between EO and OO). Infact, that quote is an exact one when I
first had a sit down with my Coptic priest and quized them how the Coptic church is different then EO (other then Chalcedon).
