Anglicans don't believe anything as best I can tell, and the Sea of Faith Anglicans rather bizarrely don't even believe in god, though personally if I were an Anglican I'd expect my bloody priest to believe in god at minimum. Not to do so seems a bit of a trades description infringement to me...
It remains a moment of great strangeness to me to realize that someone like myself is probably darn near orthodox compared to most of the people who attend my Episcopal congregation.
My priest seemed to basically not really believe in God either, rather, he seemed to treat the concept of God as an abstract notion of some moral utility. He was probably more skeptical about the concetp of a true supernatural than some atheists I have known.
Some of the classes and groups at my church seemed to have more in common with neo-paganisms than what one might identify as Christianity.
Mind you, there were still a number of folks, mostly older (relatively speaking, most everyone in that church would be old by my standards), who held a much more traditional outlook on matters. There was actually an underbelly of conflict between these two factions, well, I say "conflict", but that's far too strong a word for it I think, and if you go looking for it you'd probably never find it. The nature of such a mellow group of people I suppose.
All in all I always felt a bit strange there in some ways. I actually spent very little time actually talking about religion, because for being in a church, it seemed the one thing that one was least likely to find a common ground on.
I gravitated to the place because of this phenomenon however, because it's sort of endemic of what seems to be a very exploratory, self-examinative approach to theology and personal religion than what one finds in the vast majority of American churches in particular. That and, partly as a result of this tendency, there's is absolutely a leftward lean to the more politicized issues in the Episcopal Church, and a good majority of it's parishioners are card carrying liberals. My views on homosexuality in particular basically make me unwelcome anywhere else in American Christianity, whereas at my church there were posters for GLAAD.
Sadly, it is also that very issue that is threatening to tear apart the Episcopal Church, both in America, with a number of more conservative congregations threatening or already deciding to sever themselves from the body as a result, and with the Anglican community abroad, most especially due to pressures from the much more conservative African dioceses.
