5 You will, by the favour of God, attain to a riper age, and then you will judge what kind of bishop he is who subjects the rights of the priesthood to laymen. Your father, by the favour of God a man of riper age, used to say: It is not my business to judge between bishops. Your Clemency now says: I ought to judge. And he, though baptized in Christ, thought himself unequal to the burden of such a judgment, does your Clemency, who have yet to earn for yourself the sacrament of baptism, arrogate to yourself a judgment concerning the faith, though ignorant of the sacrament of that faith?
