Don't Fear The Schism
I'll take that woman's Episcopalia-dar as warrant for me to pronounce on church politics. My pronouncement today is: don't fear the schism. Anglicans from other parts of the world are drawing up the battle lines to pressure the Episcopalians into backing down from their pro-equality stand. They don't appear satisfied with the US church's wishy-washy attempts to compromise by giving lip service to gay rights while placing a moratorium on practicing it. So if it comes down to it, justice is more important than friendship. Having some foreign bishops refuse to drink some wine next to you is a price worth paying for the freedom to unreservedly minister to the needs of all your members.
(Then again, I really don't get all the rules about who can give or share communion with who. It seems to take something that should be a symbol of shared base-level belief and turns it into a certification of detailed doctrinal purity.)
