The Presiding Bishop of the Episcopal Church Writes the Standing Committe of the Diocese of Fort Worth--Southern Cone
You can read it all here.
There is no canon of the TEC, by the way, that gives the Presiding Bishop authority to "unrecognize" a Standing Committee. But there is also now not anyone left inside of TEC who is going to interfere with PB Schori's wishes. She has clearly made a habit of expanding the PB's alleged powers beyond their canonical scope. Were I still a member of the Episcopal church I would be quite concerned about this power grab. As it is, I wish those still inside TEC good fortune in their relations with their Presiding Bishop.
