Council of Trent: Session XXV, Purgatory and Sacred Images, DECREE CONCERNING PURGATORY.

DECREE CONCERNING PURGATORY.

Whereas the Catholic Church, instructed by the Holy Ghost, has, from the sacred writings and the ancient tradition of the Fathers, taught, in sacred councils, and very recently in this oecumenical Synod, that there is a Purgatory, and that the souls there detained are helped by the suffrages of the faithful, but principally by the acceptable sacrifice of the altar; the holy Synod enjoins on bishops that they diligently endeavour that the sound doctrine concerning Purgatory, transmitted by the holy Fathers and sacred councils, be believed, maintained, taught, and every where proclaimed by the faithful of Christ. But let the more difficult and subtle questions, and which tend not to edification, and from which for the most part there is no increase of piety, be excluded from popular discourses before the uneducated multitude. In like manner, such things as are uncertain, or which labour under an appearance of error, let them not allow to be made public and treated of. While those things which tend to a certain kind of curiosity or superstition, or which savour of filthy lucre, let them prohibit as scandals and stumbling-blocks of the faithful. But let the bishops take care, that the suffrages of the faithful who are living, to wit the sacrifices of masses, prayers, alms, and other works of piety, which have been wont to be performed by the faithful for the other faithful departed, be piously and devoutly performed, in accordance with the institutes of the church; and that whatsoever is due on their behalf, from the endowments of testators, or in other way, be discharged, not in a perfunctory manner, but diligently and accurately, by the priests and ministers of the church, and others who are bound to render this (service).
