Christus Dominus 7 states:
Let (bishops) especially embrace in brotherly affection those bishops who, for the sake of Christ, are plagued with slander and indigence, detained in prisons, or held back from their ministry. They should take an active brotherly interest in them so that their sufferings may be assuaged and alleviated through the prayers and good works of their confreres.
The key understanding, of course, is in the phrase “for the sake of Christ.” I know some Catholics are upset at the lack of criticism of bishops from their own. I guess the laity could also be included in this prayer effort. Are we invited to do so?
