I guess it might be nice to establish some sort of Celtic rite liturgical Church here in America, but I don't know if it's quite effective in any manner.
I would also question how effective such a thing would be.
Considering the diverse ethnic makeup of the first European settlers in America, not to mention that of later immigrants, I don't think its possible to establish any particular rite as that of the American people; be it Celtic, Gaelic, Latin or otherwise. This is why I'm also a tad uncomfortable with the Antiochian Western rite in the US.
I think one must allow an American rite develop gradually, as it takes root and spreads among the people. But to impose such a thing on it in its infancy seems unworkable and unnecessary.
