When, by our prayers, we release a soul from Purgatory, we have not only won his gratitude, but the gratitude of his Guardian Angel, of the Blessed Virgin Mary, to whom is soul was consecrated, and of God Himself who was enabled through us to sooner shower His blessings on it.
Our Father, Three Hail Marys, Glory Be, De Profundis
Most beloved Jesus, if I could but say: “There is a soul in Heaven at this time that owes to me its release from Purgatory, a soul that speaks to God for me, that glorifies God for me, that loves Thy Blessed Mother for me. If it were thus how happy I should be.” Release from the pains of Purgatory the soul careless and hurried in prayer. Take him to the joys of heaven, that he may evermore praise Thee and intercede for me at the hour of need.
