“So the souls in purgatory, being beloved by God, and confirmed in grace, have absolutely no impediment to prevent them from praying for us. . .we may piously believe that God makes our prayers known to them; 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...”—St. Alphonsus Liguori
