Council of Trent: Session XXV, Regulars and Nuns, Chapter IV

CHAPTER IV. A Regular shall not, without the permission of his Superior, either place himself at the service of another, or retire from his Monastery: when sent to a University for study he shall reside in a Monastery.

The holy Synod forbids, that any Regular, under the pretext of preaching, or lecturing, or of any other pious work, place himself at the service of any prelate, prince, university, community, or of any other person, or place, whatsoever, without permission from his own Superior; nor shall any privilege or faculty, obtained from others in regard hereof avail him anything. But should any one act contrary hereto, he shall be punished as disobedient, at the discretion of his Superior. Nor shall it be lawful for Regulars to withdraw from their own convents, even under the pretext of repairing to their own Superiors; unless they have been sent, or summoned, by them. And whoever shall be found to be without the order aforesaid in writing, shall be punished as a deserter from his Institute by the Ordinaries of the places. As to those who are sent to the universities for the sake of their studies, they shall dwell in convents only; otherwise they shall be proceeded against by the Ordinaries.
