In Richard Baxter's words, a "hereticating majority of Bishops" has acted. I found the best analysis here.
There is a bright spot..............
As was resolved by resolution made at the Provincial Synod in Valparaiso last November 2007, we are happy to welcome Bishop Duncan into the Province of the Southern Cone as a member of our House of Bishops, effective immediately. Neither the Presiding Bishop nor the House of Bishops of the Episcopal Church has any further jurisdiction over his ministry. We pray for all Anglicans in Pittsburgh as they consider their own relationship with The Episcopal Church in the coming weeks.
Archbishop Gregory Venables.
Lord willing, our Diocese will vote to follow him October 4.
