Council of Trent: Session 24
Chapter 9
By whom Secular Churches, not of any diocese, are to be visited.
Those things which have elsewhere been established by this same Council, under Paul III., of happy memory, and lately under our most blessed lord Pius IV., touching the diligence to be used by the Ordinaries in visiting benefices, even though exempted, the same shall also be observed in regard of those Secular churches which are said to be in no one's diocese; to wit they shall be visited by the bishop—as the delegate of the Apostolic See—whose cathedral church is the nearest, if he be able to do so; otherwise, by him whom the prelate of the said place has once for all selected in the provincial Council;—any privileges and customs whatsoever, even though immemorial, to the contrary notwithstanding.
Chapter 10
Where visitation and correction of morals are concerned, no suspension of decrees is allowed.
Bishops, that they may be the better able to keep the people whom they rule in duty and obedience, shall, in all those things which regard visitation and correction of manners, have the right and power, even as delegates of the Apostolic See, of ordaining, regulating, correcting, and executing, in accordance with the enactments of the canons, those things which, in their prudence, shall seem to them necessary for the amendment of their subjects, and for the good of their respective dioceses. Nor herein, when visitation and correction of manners are concerned, shall any exemption, or any inhibition, or appeal, or complaint, even though interposed to the Apostolic See, in any way hinder, or suspend the execution of those things which shall have been by them enjoined, decreed, or adjudged.
Chapter 11
Honorary titles, or particular privileges, shall not derogate in any way from the right of bishops.
Forasmuch as the privileges and exemptions which, under various titles, are granted to very many persons, are clearly seen to raise, in these days, confusion in the jurisdiction of bishops, and to give occasion to those exempted to lead a more relaxed life; the holy Synod ordains, that if at any time it be thought proper, for just, weighty, and well nigh compulsory causes, that certain persons be distinguished by the honorary titles of Protonotary, Acolyte, Count Palatine, Royal Chaplain, or other such titles of distinction, whether in the Roman court or elsewhere; as also that others be admitted into monasteries as Oblates, or as attached thereunto in some other way, or under the name of servants to military orders, monasteries, hospitals, colleges, or under any other title whatsoever; nothing is to be understood as being, by these privileges, taken away from the Ordinaries, so as to prevent those persons, unto whom those privileges have already been granted, or to whom they may be hereafter conceded, from being fully subject in all things to the said Ordinaries, as delegates of the Apostolic See, and this as regards Royal Chaplains, in accordance with the constitution of Innocent III., which begins Cum capella: those persons, however, being excepted, who are engaged in actual service in the aforesaid places, or in military orders, and who reside within their enclosures and houses, and live under obedience to them; as also those who have made their profession lawfully and according to the rules of the said military orders, whereof the Ordinary must be certified: notwithstanding any privileges what soever, even those of the order of Saint John of Jerusalem, and of other military orders. But, as regards those privileges which by virtue of the constitution of Eugenius, those are accustomed to enjoy who reside in the Roman Court, or who are in the household of cardinals, such privileges shall in no wise be understood to apply to those who hold ecclesiastical benefices, in so far as those benefices are concerned; but such shall continue subject to the jurisdiction of the Ordinary; any inhibitions to the contrary notwithstanding.
