Bishops are discouraged by all sorts of things from performing their duties with the fidelity and vigor that the nature of their job enjoins. I don’t envy them. It is often said that many priests decline the offer of episcopal promotion, and it is not difficult to see why. But there is a big difference between saying that doing the right thing is very difficult and saying it is impossible. We can be obliged to do what is very difficult. We can’t be obliged to do the impossible: that is, really impossible.
What should bishops be doing? They have an obligation to safeguard the salvation of all the Catholics in their dioceses, so they must act against spiritual dangers to their flock. Thus, they are under an obligation to denounce ideas or individuals who present an urgent threat to their people’s spiritual welfare, and remove people from roles in the diocese, including schools, where they threaten people’s spiritual welfare.
This kind of thing must be done in an intelligent and strategic way, and there is nothing wrong in itself in a bishop minimizing bad publicity and observing his obligations as an employer and things like that. But it is difficult to avoid the impression that even many bishops who have a reputation for orthodoxy are not doing this intelligently and strategically: they are just not doing it.
