When I first heard about the Western Rite, it sounded like a great idea to me. If these rites are truly a lost part of our Orthodox heritage, it could only be a good thing to bring them back, right? Looking into the issue, though, it seems that WR often has a tinge of ethnocentrism. How many WR enthusiasts have this assumption that "I'm of Western European descent, therefore I should have a Western European liturgy." There seems to be a lurking assumption that the Byzantine rite is "ethnic", as if Greeks, Arabs, Slavs, and Romanians are somehow ethnically unified.
I still think WR could be useful as a missionary tool, for example, as a way to ease the conversion of Anglicans or Roman Catholics. But I think we really need to stridently reject the idea that every cultural or ethnic group should have its own rite.
