I tend to agree with Sionnsar on this. 815's move smacks of hardball tactics. The strategy appears to be to continue on their chosen path, the Anglican Communion notwithstanding. The message is clear. If the Communion choses not to accept this, TEC will make it as difficult and costly as it can for any who stand in its way. If the church suffers, so much the better. (In the event of a liquidation of assets, 815 believes itself to be in the position of preferred shareholder) TEC leadership is motivated by something very different than the Holy Ghost.

I've been meaning to ask. Is there a Mr. Schori? Has he been seen in public?
