On this vigil of the Assumption of Our Lady, I thought I'd publish a beautiful prayer to Her that nobody says anymore - probably because nobody believes it anymore. It's taken from the 1957 Raccolta, possibly composed by Pope Pius IX (readers help me on this).

O Mary, Mother of Mercy and Refuge of Sinners! We beseech thee to look with pitying eyes on poor heretics and schismatics. Do thou, who art the Seat of Wisdom, enlighten the minds wretchedly enfolded in the darkness of ignorance and sin, that they may clearly recognize the Holy, Catholic, Apostolic, Roman Church to be the only true Church of Jesus Christ, outside of which neither sanctity nor salvation can be found. Call them to the unity of the one fold, granting them the grace to believe every truth of our holy faith and to submit themselves to the Supreme Roman Pontiff, the Vicar of Jesus Christ on earth, that, thus being united with us by the sweet chains divine charity, there may soon be but one fold under one and the same Shepherd; and may we all thus, O Glorious Virgin, exultantly sing forever: “Rejoice, O Virgin Mary! Thou alone hast destroyed all heresies in the whole world!” Amen.
