“Prayer, The Great Means of Obtaining Salvation and All the Graces Which We Desire of God”, Part 1, Ch. 1, Section 3: “But we may piously believe that God makes our prayers known to [the Holy Souls]; and then they, full of charity as they are, most assuredly do not omit to pray for us. St. Catharine of Bologna, whenever she desire any favor, had recourse to the souls in purgatory, and was immediately heard. She even testified that by the intercession of the souls in purgatory she had obtained many graces which she had not been able to obtain by the intercession of the saints... ...So may we expect, that is any of us ever obtains, by his prayers, the liberation of a soul from purgatory, the soul will say to God: ‘Lord, suffer not him who has delivered me from my torments to be lost.’ ...Moreover, St. Augustine says that God will cause those who in this life have most succored those holy souls, when they come to purgatory themselves, to be most succored by others... ‘eternal Father, I offer Thee this Sacrifice of the Body and Blood of Jesus Christ, with all the pains which he suffered in his life and death; and by his Passion I recommend to Thee the souls in Purgatory, and especially that of,’ etc. And it is a very charitable act to recommend, at the same time, the souls of all those who are at the point of death.” St. Alphonsus de Liguori,
