The worldwide Anglican Communion has been unable to discipline or expel the Americans, and it appears at this point that the Anglican Communion as such will cease to exist on or after September 30 of this year.
As a refugee from that dreadful excuse for a church who should have shaken the dust from my sandals long before the consecration of the Bishop of New Hampshire, I am sadly familiar with all the details of the controversy.

As for why the Episcopagans have come up in this discussion, they illustrate just exactly what you can get away with by claiming Holy Spirit-guided Scriptural interpretation when there is no authoritative leadership.
