But I thought that was the Anglican tradition.
The Most Rev Katharine Jefferts Schori, the Presiding Bishop of the Episcopal Church, said that bishops setting up shop in other dioceses is "totally opposed to a traditional Christian understanding of how bishops relate to each other. That's the biggest difficulty. They're setting up as something else in the same geographical territory." (Link)
But if bishops hadn't setup as something else in the same territory back in the 16th Century, there wouldn't be an Anglican Church to fall apart today. They'd still be Catholic.
