Heretics. And even not that cool ones.
pretty much that's my thought. Not that I'm a religious scholar, but my impression is that it's basically Catholic-lite, and purulently so.
I have attended Episcopalian mass a few times, although it has probably been at least 25 years, but my distinct impression is that the Episcopal Church is basically the Americanization of the Church of England. I could be wrong, and I'd welcome any attempt to correct my misapprehension.
I don't really think there are heretics, because I don't think the political organization that is the Roman Church as any claim on the ultimate religion, but I do think that Episcopalianism is just a very slight modification of it, but with less political power and with none of the "cool"ness of the modern American flavors of Christianity, which features Joel "God wants you to be rich" Osteen. So I think I understand your tongue-in-cheek remark and I think that I mostly agree with it.
