II. The case of the more serious offenders must be reserved for the present.
But concerning those who have sinned more gravely in this matter, and claimed for themselves a higher place in the same unhappy synod, in order to irritate the simple minds of their lowlier brethren by their pernicious arrogance, if they return to their right mind, and ceasing to defend their action, turn themselves to the condemnation of their particular error, if these men give such assurance of penitence as shall seem indisputable, let their case be reserved for the maturer deliberations of the Apostolic See, that when all things have been sifted and weighed, the right conclusion may be arrived at about their real actions. And in the Church over which the Lord has willed you to rule, let none such as we have already written have their names read at the altar until the course of events shows what ought to be determined concerning them.
