Council of Trent: Session 25
Chapter 9
Convents of Nuns immediately subject to the Apostolic See shall be governed by the Bishops; but others, by those deputed in the General Chapters, or by other Regulars.
Those convents of nuns which are immediately subject to the Apostolic See, even those which are called by the name of Chapters of St. Peter, or of St. John, or by whatsoever other name they may be designated, shall be governed by the bishops, as the delegates of the Apostolic See; anything to the contrary notwithstanding. But those which are governed, by persons deputed in general Chapters, or by other Regulars, shall be left under their care and conduct.
Chapter 10
Nuns shall confess and communicate once a month; an extraordinary Confessor shall be assigned them by the Bishop. The Eucharist shall not be reserved within the enclosure of the Convent.
Bishops and other Superiors of convents of nuns, shall take particular care that the nuns be admonished, in their constitutions, to confess their sins, and to receive the most holy Eucharist, at least once a month, that so they may fortify themselves, by that salutary safeguard, resolutely to overcome all the assaults of the devil. But besides the ordinary confessor, the bishop and other superiors shall, twice or thrice a year, offer them an extraordinary one, whose duty it shall be to hear the confessions of all the nuns. But that the most holy body of Christ be kept within the choir, or the enclosure of the convent, and not in the public church, the holy Synod forbids it; any privilege or indult whatsoever notwithstanding.
Chapter 11
In Monasteries, which are charged with the cure of the souls of laymen, they who exercise that cure shall be subject to the Bishop, and be by him previously examined, with certain exceptions.
In monasteries, or houses whether of men, or of women, which are charged with the cure of souls of other Secular persons besides those who belong to the household of those monasteries, or places; the individuals, whether Regulars or Seculars, who exercise that cure, shall be immediately subject, in whatsoever pertains to the said cure and the administration of the sacraments, to the jurisdiction, visitation, and correction of the bishop in whose diocese those places are situated; nor shall any, not even such as are removable at pleasure, be deputed thereunto, save with the consent of the said bishop, and after having been previously examined by him, or by his vicar; the monastery of Cluny with its limits being excepted; and excepting also monasteries, or places, in which abbots, generals, or the heads of orders, have their usual principal residence; as also the other monasteries, or houses, in which the abbots, or other Superiors or Regulars, exercise episcopal and temporary jurisdiction over the parish priests and their parishioners; saving, however, the right of those bishops who exercise a greater jurisdiction over the places, or persons above-named.
Chapter 12
Episcopal censures, and festivals appointed in the diocese, shall be observed even by Regulars.
Censures and interdicts,—not only those emanating from the Apostolic See, but also those promulgated by the Ordinaries,—shall, upon the bishop's mandate, be published and observed by Regulars in their churches. The festival days also which the said bishop shall order to be observed in his own diocese, shall be kept by all exempted persons, even though Regulars.
