Just bumped into a new site called Arrivals and Departures. The host is listing congregations that have split from the Episcopal Organization since it decided that homosexuality was its primary mission in 2003. My guess is that the list of sorties is going to be waaaaaaaaaay longer than the list of "Arrivals" (new Episcopal churches started since 2003).
I've emailed to host to see if churches that just plain shut down will be counted as departures. For example, historic Church of the Messiah in Wounded Knee has simply disappeared from the Diocesan directory.
One of the tricks used by The Episcopal Organization leaders is to count any building as a "church", even if there's no congregation. As I've pointed out before, the Diocese of South Dakota claims some 90 churches, but with Diocesan average Sunday attendance at about 2,000, that would mean an average attendance of around 23. Since there are churches here known to have attendance much higher than 23, it means that a good number of the "90 churches" are empty buildings. (The Presiding Bishop uses this same word trick on a national level, claiming that only a small number of buildings have left the denomination rather than revealing the hundreds of thousands of people who've left.)
