We decree that those who give credence to the teachings of the heretics, as well as those who receive, defend, and patronize them, are excommunicated; and we firmly declare that after any one of them has been branded with excommunication, if he has deliberately failed to make satisfaction within a year, let him incur ipso jure the stigma of infamy and let him not be admitted to public offices or deliberations, and let him not take part in the election of others to such offices or use his right to give testimony in a court of law. Let him also be intestable, that he may not have the free exercise of making a will, and let him be deprived of the right of inheritance. Let no one be urged to give an account to him in any matter, but let him be urged to give an account to others. If perchance he be a judge, let his decisions have no force, nor let any cause be brought to his attention. If he be an advocate, let his assistance by no means be sought. If a notary, let the instruments drawn up by him be considered worthless, for, the author being condemned, let them enjoy a similar fate. In all similar cases we command that the same be observed. If, however, he be a cleric, let him be deposed from every office and benefice, that the greater the fault the graver may be the punishment inflicted.
If any refuse to avoid such after they have been ostracized by the Church, let them be excommunicated till they have made suitable satisfaction. Clerics shall not give the sacraments of the Church to such pestilential people, nor shall they presume to give them Christian burial, or to receive their alms or offerings; otherwise they shall be deprived of their office, to which they may not be restored without a special indult of the Apostolic See. Similarly, all regulars, on whom also this punishment may be imposed, let their privileges be nullified in that diocese in which they have presumed to perpetrate such excesses.
But since some, under “the appearance of godliness, but denying the power thereof,” as the Apostle says (II Tim. 3: 5), arrogate to themselves the authority to preach, as the same Apostle says: “How shall they preach unless they be sent?” (Rom. 10:15), all those prohibited or not sent, who, without the authority of the Apostolic See or of the Catholic bishop of the locality, shall presume to usurp the office of preaching either publicly or privately, shall be excommunicated and unless they amend, and the sooner the better, they shall be visited with a further suitable penalty. We add, moreover, that every archbishop or bishop should himself or through his archdeacon or some other suitable persons, twice or at least once a year make the rounds of his diocese in which report has it that heretics dwell, and there compel three or more men of good character or, if it should be deemed advisable, the entire neighborhood, to swear that if anyone know of the presence there of heretics or others holding secret assemblies, or differing from the common way of the faithful in faith and morals, they will make them known to the bishop. The latter shall then call together before him those accused, who, if they do not purge themselves of the matter of which they are accused, or if after the rejection of their error they lapse into their former wickedness, shall be canonically punished. But if any of them by damnable obstinacy should disapprove of the oath and should perchance be unwilling to swear, from this very fact let them be regarded as heretics.
We wish, therefore, and in virtue of obedience strictly command, that to carry out these instructions effectively the bishops exercise throughout their dioceses a scrupulous vigilance if they wish to escape canonical punishment. If from sufficient evidence it is apparent that a bishop is negligent or remiss in cleansing his diocese of the ferment of heretical wickedness, let him be deposed from the episcopal office and let another, who will and can confound heretical depravity, be substituted.
