This schism is exactly the goal of the liberal movement.
The real issue is too follow the money, here the property holdings alone of ECUSA exceeds $2 Billion, then there are foundations and investments.
Andrew Sullivan on C-Span stated that homosexual acceptance would not occur until the homosexual lobby had control of a mainstream religion and its resources.
Bingo. Am I the only one who recalls parishioners locked out of their own churches for refusal to "adhere" to the new schizm within the church, of course, their latest is to ordain an open homosexual. Yes, they were thereby, "sanctioning female and gays" able to "seize" churches. The real estate value is awesome to behold.
It would be interesting to do a study of this. But I suspect that the invested capital is probably not enough, by itself, to maintain these very expensive churches. Your typical Episcopal church is a stone gothic building of considerable size, probably with slate roof, lead or copper flashing, and all the rest of it. That kind of building can last a long time without maintenance, but when it needs maintenance it can be very expensive. Will it be possible to maintain these buildings without wealthy and substantial congregations?
I used to be an Episcopalian. Your typical congregation used to be the richest people and the oldest families in town. But that is gradually ceasing to be true. Liberal rich people no longer feel that much of a need to attend church or make a show of religion. I think there's a real risk that these folks will take over a huge, expensive network of white elephant churches, while real Christians will move out and build something cheaper for themselves.
People have also said that the Catholic Church is worth trillions. It is, if you count all those art treasures, churches, hospitals, seminaries, colleges, and schools. But they can't be sold, they must be maintained, and the trust funds aren't big enough to do it. You need living and supportive Catholics. Similarly, no matter how wealthy, ECUSA needs living and supportive Episcopalians.
