I've got to admit I'm a little confused, not by you, but by this O'Malley, McCarrick, Kerry, connection.
Only one of them can be Kerry's official Bishop, and the other just incidental as to where he attends Church when he is away from home. What one Bishop does should have no real bearing on the actions of the other. At least that's how it seems to work in the real world in the USA.
Is it your position that one of the Bishops is weak, and the other is honoring that weakness?
