There are religious congregations and pious associations specially devoted to the relief of the souls in Purgatory. St. Vincent de Paul ordered the priests of his congregation never to go to meals without first saying the _De Profundis_ for the souls in Purgatory. The Church ends all the prayers of the divine office with: "May the souls of the faithful departed, through the mercy of God, rest in peace." One may turn away with a sad thought from a tomb on which is not engraved: "May he rest in peace," or on which a cross--the emblem of our hope in God and in a happy resurrection--does not figure. We exhort you, beloved children in Christ, to entertain an earnest charity towards the souls in Purgatory. You loved them during life; do not let it be said: "Out of sight, out of mind." Love them in death or, living, wishing earnestly to go to God. This charity will greatly help yourselves. If a cup of cold water given to a servant of God shall not go without its reward, how much more a cup of celestial grace, that will shorten the time in the flames of Purgatory of a soul that most ardently longs to see God, who desires it Himself with great love, and will reward those who shorten the exile of His dear servants. "Those," says St. Alphonsus Liguori, "who succor the souls in Purgatory will be succored in turn by the gratitude of those whom they have relieved, and who enjoy sooner, by their prayers, the beatific vision of God." * * * * * The Council of Trent, under the inspiration of the Holy Ghost, has made decrees on the subject which bind the consciences of the faithful. In the Thirteenth Canon of the Sixth Session it decrees "that if any one should say that a repentant sinner, after having received the grace of justification, the punishment of eternal pains being remitted, has no temporary punishment to be suffered, either in this life or in the next, in Purgatory, before he can enter into the Kingdom of God, let him be anathema." Though King David was assured, after his sincere repentance, that his sin was forgiven, yet the Prophet told him that he had still to suffer by the death of his child. In the Twenty-fourth Session and Third Canon the Holy Council defines that the Sacrifice of the Mass is propitiatory, both for the living and the dead, for sins, punishments, satisfactions, and for other necessities, according to Apostolic traditions; and the Bishop, when he ordains, places the patena and chalice, with the bread and wine, in the hands of the young priest and says to him: "Receive the power to offer to God the Sacrifice of the Mass, as well for the living as for the dead, in the name of the Lord. Amen."
