1. It had been indeed long ago decreed that Pelagius and Celestius, the authors of an execrable heresy, should, as pestilent corruptors of the Catholic truth, be expelled from the city of Rome, lest they should, by their baneful influence, pervert the minds of the ignorant. In this our clemency followed up the judgment of your Holiness, according to which it is beyond all question that they were unanimously condemned after an impartial examination of their opinions. Their obstinate persistence in the offence having, however, made it necessary to issue the decree a second time, we have enacted further by a recent edict, that if any one, knowing that they are concealing themselves in any part of the provinces, shall delay either to drive them out or to inform on them, he, as an accomplice, shall be liable to the punishment prescribed.
2. To secure, however, the combined efforts of the Christian zeal of all men for the destruction of this preposterous heresy, it will be proper, most dearly beloved father, that the authority of p. 557 your Holiness be applied to the correction of certain bishops, who either support the evil reasonings of these men by their silent consent, or abstain from assailing them with open opposition. Let your Reverence, then, by suitable writings, cause all bishops to be admonished (as soon as they shall know, by the order of your Holiness, that this order is laid upon them) that whoever shall, through impious obstinacy, neglect to vindicate the purity of their doctrine by subscribing the condemnation of the persons before mentioned, shall, after being punished by the loss of their episcopal office, be cut off by excommunication and banished for life from their sees. For as, by a sincere confession of the truth, we ourselves, in obedience to the Council of Nice, worship God as the Creator of all things, and as the Fountain of our imperial sovereignty, your Holiness will not suffer the members of this odious sect, inventing, to the injury of religion, notions new and strange, to hide in writings privately circulated an error condemned by public authority. For, most beloved and loving father, the guilt of heresy is in no degree less grievous in those who either by dissimulation lend the error their secret support, or by abstaining from denouncing it extend to it a fatal approbation.
