Council of Trent: Session 14
Chapter 9
The Benefices of one Diocese shall not, under any pretext, be united to the Benefices of another Diocese.
And forasmuch as it is with very good reason that dioceses and parishes have been made distinct, and to each flock their proper pastors have been assigned, and to inferior churches their rectors, each to take care of his own sheep, that so ecclesiastical order may not be confounded, or one and the same church belong in some sort to two dioceses, not without grievous inconvenience to such as are subject thereunto; the benefices of one diocese, be they even parochial churches, perpetual vicarages, simple benefices, prestimonies, or prestimonial portions, shall ‸not be united in perpetuity to a benefice, monastery, college, or even to a pious place, of another diocese, not even for the sake of augmenting divine worship, or the number of beneficiaries, or for any other cause whatsoever; thus herein explaining the decree of this holy Synod on the subject of these unions.
Chapter 10
Regular Benefices shall be conferred on Regulars.
Benefices of Regulars that have been accustomed to be granted in title to professed Regulars, when they happen to become vacant by the death of the titulary incumbent, or by his resignation, or otherwise, shall be conferred on religious of that order only, or on persons who shall be absolutely bound to take the habit, and make that profession, and upon none others, that they may not wear a garment that is woven of woollen and linen together.
Chapter 11
Those transferred to another order shall remain under obedience in enclosure, and shall be incapable of Secular Benefices.
But forasmuch as Regulars, after being transferred from one order to another, ordinarily obtain permission easily from their superior to remain out of their monastery, whereby occasion is given of their wandering about and apostatizing; no prelate or superior of any order shall be allowed, by virtue of any faculty whatsoever, to admit any individual to the habit and to profession, except with the view that he shall remain perpetually in enclosure under obedience to his own superior, in the order itself to which he is transferred; and one so transferred, even though he be a canon Regular, shall be wholly incapable of Secular Benefices, even of cures.
Chapter 12
No one shall obtain a right of patronage, except by means of a foundation, or an endowment.
No one, moreover, of whatsoever ecclesiastical or Secular dignity, can, or ought to, obtain, or acquire a right of patronage, for any other reason whatever, but that he has founded, and built anew, a church, benefice, or chapel; or that he has competently endowed, out of his own proper and patrimonial resources, one already erected, which, however, is without a sufficient endowment. But, in case of such foundation or endowment, the institution thereof shall be reserved to the bishop, and not to some other inferior person.
Chapter 13
The Presentation shall be made to the Ordinary; otherwise the Presentation and Institution shall be null.
Furthermore, it shall not be lawful for a patron, under pretext of any privilege whatsoever, to present any one, in any way, to the benefices which are under his right of patronage, except to the ordinary bishop of the place, to whom the providing for, or the institution to, the said benefice would, that privilege ceasing, of right belong; otherwise the presentation and institution, which may have followed, shall be null, and as such reputed.
Chapter 14
That the Mass, Order, and Reformation, shall be next treated of.
The holy Synod declares, moreover, that, in the next Session, which It has already decreed is to be holden on the twenty-fifth ‸day of January, of the ensuing year, MDLII,—It will, together with the sacrifice of the mass, also apply itself to, and treat of the sacrament of order, and that the subject of reformation will be prosecuted.
