If you look around, you see the larger society divided just so. Consider how the Supreme Court operates. For "liberal Episcopalians," think David Souter (a real-life Episcopalian from New Hampshire) and such like who see the Constitution as an ever-evolving document. For "conservative Episcopalians," think defenders of the document as historically interpreted, the likes of Clarence Thomas (a real-life conservative Episcopalian until he went to Rome).
Authority is the problem our society has in spades, hearts, diamonds and clubs. If. you're white, black or brown, and you say eternal truths aren't subject to referendum, you have a different view of life, obviously, than those who are white, black or brown and ask, what's so "eternal" about some old truth?
The realignment of Anglicanism, now commenced under Gene Robinson's inadvertent patronage, forges an alliance of whites, blacks and browns -- who, as it seems to them, put heavenly standards beyond the reproach of earthly ones. What they believe matters more than the place they were born or the way they talk and dress.
This thing -- this realignment -- is inestimably large, with inestimable consequences. Anglicans are its central actors at the moment. The cast will likely expand as differences deepen and new affinities present themselves. The West isn't going to be the same at the end as at the start; it may actually end up better.
