Well, this EC views the pan-Orthodox Council that condemned ethno-phyletism in terms of what it actually condemned, that is, the issue of the Bulgarian jurisdiction receiving only Bulgarians.
What does this point have to do with the Ukrainian situation is beyond me.
No Ukrainian Orthodox or EC jurisdiction forbids non-Ukrainians from being members. The UOC-KP, in fact, has, at last count, three Russian eparchies.
The Ukrainian Orthodox continues to glorify many non-Ukrainians as Saints of its Church (compare this to the historical Greek tradition in this regard).
In fact, the national Orthodox Churches in Europe and elsewhere have tended to focus on serving their own communities which are largely composed of citizens of the nations where they are located.
This issue comes up sporadically where Western converts are concerned who feel alienated in parishes which are linked to specific cultural identities connected to their homeland jurisdictions.
Again, no one in Ukraine (or elsewhere in recent memory) forbids people of other cultural backgrounds to join it.
The UGCC also had, at one point, a group of Old Rite Russian Orthodox in communion with it (and with Rome).
As DMD said, the term ethnophyletism gets bandied about a lot without fulling understanding what was specifically condemned by that Orthodox council in 1872 (I think it was that year).
