Council of Trent: Session 25
On Regulars and Nuns
The same sacred and holy Synod, prosecuting the subject of reformation, has thought fit that the things following be ordained.
Chapter 1
All Regulars shall order their lives in accordance with what is prescribed by the rule which they have professed; Superiors shall sedulously provide that this be done.
Forasmuch as the holy Synod is not ignorant how much splendour and utility accrue to the Church of God, from monasteries piously instituted and rightly administered; It has,—to the end that the ancient and regular discipline may be the more easily and promptly restored, where it has fallen away, and may be the more firmly maintained, where it has been preserved,—thought it necessary to enjoin, as by this decree It doth enjoin, that all Regulars, as well men, as women, shall order and regulate their lives in accordance with the requirements of the rule which they have professed; and above all that they shall faithfully observe whatsoever belongs to the perfection of their profession, such as the vows of obedience, poverty, and chastity, as also all other vows and precepts that may be peculiar to any rule or order, respectively appertaining to the essential character of each, and which regard the observance of a common mode of living, food, and dress. And all care and diligence shall be used by the Superiors, both in the general and in the provincial Chapters, and in their visitations, which they shall not omit to make in their proper seasons, that these things be not departed from; it being certain, that those things which belong to the substance of a regular life cannot be by them relaxed. For if those things which are the basis and the foundation of all regular discipline be not strictly preserved, the whole edifice must needs fall.
Chapter 2
Property is wholly prohibited to Regulars.
For no Regular, therefore, whether man, or woman, shall it be lawful to possess, or hold as his own, or even in the name of the convent, any property moveable or immoveable, of what nature soever it may be, or in what way soever acquired; but the same shall be immediately delivered up to the Superior, and be incorporated with the convent. Nor shall it henceforth be lawful for Superiors to allow any real property to any Regular, not even by way of having the interest, or the use, the administration thereof, or in commendam. But the administration of the property of monasteries, or of convents, shall belong to the officers thereof only, removable at the will of their Superiors.
The Superiors shall allow the use of moveables, in such manner as that the furniture of their body shall be suitable to the state of poverty which they have professed; and there shall be nothing therein superfluous, but at the same time nothing shall be refused which is necessary for them. But should any one be discovered, or be proved, to possess anything in any other manner, he shall be deprived during two years of his active and passive voice, and also be punished in accordance with the constitutions of his own rule and order.
