GiC's patriarch loves the Pope, interestingly enough.
I'm guessing GiC's problem with the Pope is that he is not more like Katherine Jefferts-Schori and Gene Robinson. Why, if only we were more like those two, our churches would become so much more relevant. And just think! We could have more rainbow mitres!
And membership would go through the roof just like RC Mass attendance after Vatican II. As our father among the saints John Shelby Spong hath said Christianity must change or die.
Seriously, he's marginal - Dr J-S and the Bishop of New Hampshire are in their 50s, the youngest people who think that sort of thing is cool.
It's like the generational divide in the Roman Church between older liberals and younger relative conservatives.
TEC is still a Christian church as shown by the current Prayer Book and probably will remain so for some time.
The new centre there has women priests and gay weddings but like the Archbishop of Canterbury believes the creeds and is even liturgically conservative compared to much of RC.
It deserves to be asked to leave the mostly Protestant, non-white, non-rich and non-liberal Anglican Communion for breaking faith with it on the gay thing.
Which wouldn't affect 90 per cent of Episcopalians in any way.
The only inevitable outcomes here are a few parishes will be split and a few others squashed. On both sides.
I can see membership dropping to below a million (lots of people are leaving and the members tend not to have kids) but it won't die out - it'll keep drawing its share of disaffected Romans and evangelicals who are (or fancy themselves) hip and urbane, like good production values in liturgy (thanks for that one, Keble) and have itching ears or want to be 'affirmed' in whatever turns them on. (How it works: the upper middle class accepts and wants something, like women ministers or gay weddings; TEC delivers then cooks up a theology for it) Part of the snob appeal now is not so much ethnicity or class but intellectual vanity: 'we're the thinking person's church not like those dumb Roman Catholics and evangelicals'.
(Comparison: the real, Sunday-attendance numbers in several American Orthodox denominations are only in the tens of thousands.)
