The Episocal Church of the USA (ECUSA) is part of the Anglican communion but a separate entity. (It dates back to that 1776 revolution thing and the need to form a church that did not have the monarch of England as its head honcho.)
The titles to most church properties are held by the local diocese. The Archbishop of Canterbury has no authority in the matter.
If the church stays within Anglicanism, why would these "loving" folks like Bish Robinson object to "differently-minded" congregations moving themselves and their property under the guidance of a different Anglican primate?
I mean, after all, it's not about money, is it?
