As an Episcopalian, allow me to offer that a denomination which believes degenrates can openly defy God and yet be embraced by men to bring the host is a dead church. Get out before the Evil One takes the pulpit ... he's already at the altar and in the lessons.
"Our tradition is one of diversity, ...."
No it isn't.
The basic strategy of the ECUSA revisionists appears to be one of falling back on the bureaucratic structures of General Convention -- it's an easy way for them to get an extra year's time. The HOB could -- and should -- call an special Convention to deal with this extraordinary situation. (And Griswold should resign, too, but neither will happen.)
Still, there is that other option -- not of fighting per se, but instead hoping to be presented with the choice of being "Of the Communion," or not of it.
I think the primates are willing to offer that choice, and I think that inaction on the part of the HOB will cause them to offer the choice sooner, rather than later. And, as usual, the HOB will be caught flat-footed when the Primates respond.
