Gene Robinson, as perhaps you know, is the first openly gay and partnered Episcopal bishop. The conservative reaction to his election and subsequent consecration sent the worldwide Anglican Communion into a crisis from which it has not yet even begun to recover.
It's an amazing thing and I often say it in speeches: you can preach a judgmental and punitive God and no one seems to mind, but if you preach a God who is too merciful, too forgiving, too loving, then there are all kinds of awful consequences.
Bishop Robinson is retiring early after a seven year episcopacy. Among other stresses of the job, he has received regular death threats throughout these past seven years.
