From another priest, by email. I especially like the clarity of his point #2:
1.Forrester should have dropped off the committee when it was clear that he would be a candidate; and 2. Mutual Ministry assumes the person that you are looking for is already there. In the case of a Bishop, I think this is possibly not the case. Also, as that Diocese has had a large loss of membership, they might benefit from a fresh perspective on mutual ministry from the outside.
