Traditional Anglican ping, continued in memory of its founder Arlin Adams. "There have been times when the proverbial plowman can read scripture better than a prelate.

Yes, I know -- very Protestant. And this is one way, the chief way actually, I remain somewhat Protestant.
And I am admittedly quite radical on this, as I always been. When a church officer, even a bishop, willfully and repeatedly goes against scripture on central doctrine, he forfeits his authority."
Not so protestant; actually quite patristic and Orthodox.
"Even if the whole universe holds communion with the [heretical] patriarch, I will not communicate with him. For I know from the writings of the holy Apostle Paul: the Holy Spirit declares that even the angels would be anathema if they should begin to preach another Gospel, introducing some new teaching." +Maximos the Confessor
