Council of Trent: Session XXIV, Reformation, Chapter XIV

CHAPTER XIV. In promotions to benefices, or in admissions into possession of the same, any deductions from the fruits, not applied to pious uses, are prohibited.

In many churches, as well cathedral as collegiate and parochial, it is understood to be the practice, derived either from the constitutions thereof, or from an evil custom, that upon any election, presentation, institution, confirmation, collation, or other provision, or upon admission to the possession of any cathedral church, benefice, canonries, or prebends, or to a participation in the revenues, or the daily distributions, there are introduced certain conditions, or deductions from the fruits, certain payments, promises, unlawful compensations, as also the profits which are in some churches called Turnorum lucra; and whereas the holy Synod detests these practices, It enjoins on bishops, that they suffer not anything of the kind to be done, unless the proceeds be converted to pious uses, nor permit any of those modes of entering (on benefices) which carry with them a suspicion of a simoniacal taint, or of sordid avarice; and they shall themselves carefully take cognizance of their constitutions, or customs in the above regards; and, those only being retained which they shall approve of as laudable, the rest they shall reject and abolish as corrupt and scandalous. And It decrees that those, who act in any way contrary to the things comprised in this present decree, incur the penalties set forth against simoniacs by the sacred canons, and divers constitutions of the Sovereign Pontiffs, all of which this Synod renews; any statutes, constitutions, customs, even though immemorial, even though confirmed by apostolic authority, to the contrary notwithstanding; the bishop, as the delegate of the Apostolic See, having power to take cognizance of any surreption, obreption, or defect of intention, in regard thereof.
