Council of Trent: Session XXV, Reformation, Chapter IV

CHAPTER IV. Where the number of Masses to be celebrated is excessive, Bishops, Abbots, and Generals, shall make such regulation as shall seem to them expedient.

It frequently happens, in divers churches, either that so great a number of masses is required to be celebrated on account of various legacies from persons deceased, that it is not possible to comply therewith on the particular days prescribed by the testators; or, that the alms left for the celebration thereof is so slight that it is not easy to find any one willing to undertake the duty; whereby the pious intentions of the testators are frustrated, and occasion is given for burthening the consciences of those who are concerned in the aforesaid obligations. The holy Synod, being desirous that these legacies for pious uses be satisfied in the most complete and useful manner possible, empowers bishops in diocesan Synod, and likewise abbots and generals of orders in their general Chapters, to ordain, in regard hereof, whatsoever in their consciences they shall, upon a diligent examination of the circumstances, judge to be most expedient for God's honour and worship, and the good of the churches, in those churches aforesaid which they shall find stand in need of some regulation in this matter, in such wise however that a commemoration be always made of the departed who, for the welfare of their souls, have left the said legacies for pious uses.
