If you say the Rosary faithfully until death, I do assure you that, in spite of the gravity of your sins you shall receive a never-fading crown of glory. Even if you are on the brink of damnation, even if you have one foot in hell, even if you have sold your soul to the devil as sorcerers do who practice black magic, and even if you are a heretic as obstinate as a devil, sooner or later you will be converted and will amend your life and will save your soul, if — and mark well what I say — if you say the Holy Rosary devoutly every day until death for the purpose of knowing the truth and obtaining contrition and pardon for your sins.
-St. Louis de Monfort
O Immaculate and wholly-pure Virgin Mary, Mother of God, Queen of the world, hope of those who are in despair; thou art the joy of the Saints; thou art the peacemaker between sinners and God; thou art the advocate of the abandoned, the secure haven of those who are on the sea of the world; thou art the consolation of the world, the ransom of slaves, the comfortress of the afflicted, the salvation of the universe. O great Queen, we take refuge in thy protection: ‘We have no confidence but in thee, O most faithful Virgin.’ After God thou art all our hope. We bear the name of thy servants; allow not the enemy to drag us to Hell. I salute thee, O great Mediatress of peace between men and God, Mother of Jesus our Lord, who is the love of all men and of God, to whom be honor and benediction with the Father and the Holy Spirit. Amen.
-Prayer by St. Ephrem
