4. Special care must be taken to warn bishops, vicars-general [provisores], visitors, and vicars, that they are not allowed to mention crimes of heresy or the like in their public letters and proclamations during visit; for his Holiness has referred and submitted such cases to the most illustrious inquisitor-general and the inquisitors appointed by him in all the kingdoms and seigniories of his Majesty. Therefore they shall try these cases privatim, which other judges can neither try, nor undertake to investigate, nor otherwise handle. Since in visitations crimes often come to light which must be tried by the Holy Office, warning must be given that these should be submitted to the Inquisition, with all secrecy and without the knowledge of the guilty party. The same must be done in suppressing the titles of vicars, in annulling the head of processes and charges made by the bishops, and in suppressing the title of inquisitor-inordinary; for in these regions the jurisdiction over the crime of heresy is wholly apostolic, except in case of the Indians. If any doubt, contention, or difficulty regarding the execution of this clause should arise, the commissary, without further inquiry, shall promptly notify us that he has warned, in especially polite and respectful language, the prelate concerned, to whom he must show much reverence—for the reverential respect which is due him should not be in the least abated by the privilege of the commissary’s office.
