5. Prayer at the End of the Rosary (Oratio ad Finem Rosarii Dicenda)

A Prayer of Trust in Our Lady’s Intercession

The Rosary has always held a place of utmost importance in the devotional life of true Catholics. This powerful prayer, given by Our Lady herself, has been a weapon against heresy, sin, and apostasy throughout the ages. Yet, in our times—marked by confusion and darkness following the spiritual devastation of Vatican II—it is more important than ever that we cling to authentic Catholic devotions untouched by the errors of the Novus Ordo sect.

The “Prayer to be Said at the End of the Rosary,” also known as the “Oratio ad Finem Rosarii Dicenda,” is a traditional Latin prayer that encapsulates the spirit of supplication, penitence, and filial trust in the Blessed Virgin Mary. It implores God for the triumph of the Church, for peace in the world, and for the conversion of sinners—especially the conversion of those led astray by the false Conciliar religion, which emerged from the heretical Vatican II Council. This prayer is not an optional pious extra; it is a vital component of the Rosary as prescribed by true Catholic tradition prior to the Conciliar revolution. In learning and praying this powerful Latin prayer, we align ourselves with the unchanging Faith of the Church of all time, not the counter-church that emerged in the 1960s.

5. Lesson Summary

This lesson teaches the traditional Latin prayer said at the end of the Rosary, fostering devotion, reparation, and fidelity to the true Catholic Faith. It helps you deepen your spiritual life while resisting the errors of the modernist Vatican II religion.

6. Final Thought – Why Does This Prayer Matter?

Why take the time to learn and recite this prayer—especially in Latin? Because this is not merely a matter of language or custom, but of fidelity to the unchanging Catholic Faith handed down through the centuries. The “Prayer at the End of the Rosary” is a clear expression of traditional Catholic piety, one that has sadly been discarded or distorted by the post-Vatican II counterfeit church. Since the Second Vatican Council, the once-glorious edifice of the Catholic Church has been eclipsed by a modernist sect that has abandoned Latin, doctrinal clarity, and the very concept of objective truth in favor of ecumenism, novelty, and the exaltation of man over God.

In this dark age, praying the Rosary—and concluding it with this traditional Latin prayer—is a direct act of spiritual resistance and reparation. It connects us to generations of saints, martyrs, and faithful Catholics who upheld the Faith in the face of persecution, heresy, and apostasy. The Latin language itself, as the sacred language of the Church, is a sign of unity, continuity, and holiness, and the Church has always esteemed it as a safeguard against doctrinal corruption. By learning and reciting this prayer in Latin, we preserve not just words, but a mindset: one of humility, reverence, and submission to the will of God and the authority of true tradition.

Most importantly, this prayer reminds us to entrust everything to Our Lady—She who has been foretold to crush the head of the serpent. In these times of unprecedented spiritual deception, praying this traditional prayer with sincerity and devotion is a concrete way to remain faithful to the One, Holy, Catholic, and Apostolic Church—outside of which there is no salvation. This is no small matter; it is a question of eternal consequence. Hold fast to tradition. Reject the false church of Vatican II. Cling to the Rosary, and let this prayer be the echo of your soul’s cry for the triumph of the Immaculate Heart and the restoration of the true Catholic Church.
