Council of Trent: Session 7
Chapter 4
The retainer of several Benefices contrary to the Canons, shall be deprived thereof.
Whosoever shall for the future presume to accept, or to retain at the same time several cures, or otherwise incompatible Ecclesiastical Benefices, whether by way of union for life, or in perpetual commendam, or under any other name or title whatsoever, in contravention of the appointment of the sacred Canons, and especially of the Constitution of Innocent III., beginning, De multa, shall be ipso jure deprived of the said benefices, according to the disposition of the said constitution, and also by virtue of the present Canon.
Chapter 5
The holders of several Benefices with cure of souls shall exhibit their dispensations to the Ordinary, who shall provide the churches with a Vicar, assigning a suitable portion of the fruits.
The Ordinaries of the places shall strictly compel all those who hold several cures, or otherwise incompatible, Ecclesiastical Benefices to exhibit their dispensations; and they shall otherwise proceed according to the Constitution of Gregory X., published in the General Council of Lyons, beginning Ordinarii, which (Constitution) this holy Synod thinks ought to be renewed, and doth renew; adding further, that the said Ordinaries are by all means to provide, even by deputing fit vicars and by assigning a suitable portion of the fruits, that the cure of souls be not in any way neglected, and that the said benefices be nowise defrauded of the services due to them: no appeals, privileges, or exemptions whatsoever, even with a commission of special judges, and inhibitions from the same, being of avail to any one in the matters aforenamed.
Chapter 6
What unions of Benefices shall be accounted valid.
Unions in perpetuity, made within forty years, may be examined into by the Ordinaries, as delegated by the Apostolic See, and such as shall have been obtained by surreption or obreption shall be declared null. Now those are to be presumed to have been surreptitiously obtained, which having been granted within the aforenamed period, have not as yet been carried into effect wholly, or in part, as also those which shall henceforth be made at the instance of any person soever, unless it shall be certain that they have been made for lawful, or otherwise reasonable causes, which are to be verified before the Ordinary of the place, those persons being summoned whose interests are concerned: and therefore (such unions) shall be altogether of no force, unless the Apostolic See shall have declared otherwise.
Chapter 7
United Ecclesiastical Benefices shall be visited: the cure thereof shall be exercised even by perpetual vicars; who shall be deputed thereunto with a portion, to be assigned even upon a specific property.
Ecclesiastical Benefices with cures, which are found to have been always united and annexed to Cathedral, Collegiate, or other churches, or to monasteries, benefices, colleges, or other pious places of what sort soever, shall be visited every year by the Ordinaries of those places; who shall apply themselves sedulously to provide that the cure of souls be laudably exercised by competent vicars, and those even perpetual, unless the said Ordinaries shall deem it expedient for the good of the churches that it be otherwise,—which (vicars) shall be deputed thereunto by those Ordinaries, with a provision consisting of a third part of the fruits, or of a greater or less proportion, at the discretion of the said Ordinaries, which (portion) is to be assigned even upon a specific property; no appeals, privileges, exemptions, even with a commission of judges, and inhibitions from the same, being of any avail in the matters abovenamed.
