Now, has the ACC dropped the filoque? I know one of the Anglo-Catholic continuing Anglican groups has.
An Orthodox monk of whom I am very fond (whose monastery, incidentally, uses the Coverdale Psalter, rather than the translation from the LXX from Holy Transfiguration Monastery most of us English-speaking Orthodox use) has expressed the view that the non-filioquist continuing Anglicans are the only Western confession worth having ecumenical dialogs with. (Of course that was before the Latins got a Pope of Rome given to quoting Nicholas Cabasilas and Emperor Manuel II.)
I am afraid I will have to plead ignorance to this - if only because I am still very much new to the ACC and am only able to learn about it through its main website and the other members. I attended a couple of synods and learned quite a bit there, but am afraid my head can only hold so much data at a time LOL.
Only thing I can suggest is going to the main website and contacting the Archbishop there.
Best wishes...
IN re-reading your post, am also thinking the best answer I can give you is that we use the 1928 Book of Common Prayer as the basis for our worship. Our actual Sunday service is more like a High Church Episcopalian service, with Morning and Evening Prayers straight from the BCP, as well as the Litany, and Decalogue, among other services. I have no idea what service in Vatican I was like, as I was born in 1967, and raised Vatican II (although I daresay the priest who led our little parish was an Irish traditionalist and balked at some of the more modern music brought in during the 70s. I confess it right now: I was part of the Folk Group movement, if only because the leader of our little guitar choir was a fab guitarist.)
