The month of October is dedicated to the Holy Rosary. The feast of the Rosary is held on October 7th in memory of the glorious and triumphant victory at the battle of Lepanto. That battle was the most convincing military victory that proved without a doubt the great power of the Rosary.
According to an account by fifteenth-century Dominican, Alan de la Roch, Mary appeared to St. Dominic in 1206 after he had been praying and doing severe penances because of his lack of success in combating the Albigensian heresy. Mary praised him for his valiant fight against the heretics and then gave him the Rosary as a mighty weapon, explained its uses and efficacy, and told him to preach it to others.
Since the prayers of the Rosary come from such excellent sources — from Our Lord Himself, from inspired Scripture, and from the Church — it is not surprising that the Rosary is so dear to our Blessed Mother and so powerful with heaven.
If we consider the power of the Rosary as seen in its effects, we find a great abundance of proofs of its wonderful value. Many are the favours granted to private individuals through its devout recitation: there are few devoted users of the Rosary who cannot testify to experiencing its power in their own lives. If we turn to history, we see many great triumphs of the Rosary.
The Rosary had its origin in the liturgical mentality of former ages. Even at the present time it is called “Mary’s Psalter.” There still are Catholics who consider the 150 Hail Marys a substitute for the 150 psalms for those persons who neither have the time, the education, nor the opportunity to pray the Hours of the Divine Office. Thus “Mary’s Psalter” is a shortened, simplified “breviary” — alongside the common Hour-prayer of the Church. — The Church’s Year of Grace, Dr. Pius Parsch
The Rosary is Christocentric setting forth the entire life of Jesus Christ, the passion, death, resurrection and glory. Of course, the Rosary honours and contemplates Mary too, and rightly so, for the same reason that the Liturgical Year does likewise: “Because of the mission she received from God, her life is most closely linked with the mysteries of Jesus Christ, and there is no one who has followed in the footsteps of the Incarnate Word more closely and with more merit than she”142 (Mediator Dei). Meditation on this cycle of Joyful, Sorrowful, Glorious and Luminous Mysteries makes the Rosary not only “a breviary or summary of the Gospel and of Christian life,”(Ingravescentibus malis) but also a compendium of the Liturgical Year. Therewith the Rosary stands revealed as a dynamic teacher and nurturer of Christian faith, morality, and spiritual perfection, fostering in various ways faith, hope, charity, and the other virtues, and mediating special graces, all to the end that we may become more and more like unto Christ. — Mariology, Juniper B. Carol, O.F.M.
No form of extra-liturgical devotion to Mary has been recommended more warmly or frequently by the Popes. The authentic Rosary is a happy combination of vocal and mental prayer, each of which is essential to the devotion. It is incorrect to say that meditation is “the very essence of the Rosary devotion,” for vocal recitation of the prayers is also of the essence. Meditation is, of course, the nobler element, the “soul,” while vocal prayer is the “body” of the devotion. The Rosary, Pope Leo XIII declared, “is composed of two parts, distinct but inseparable — the meditation on the mysteries and the recitation of the prayers. It is thus a kind of prayer that requires not only some raising of the soul to God, but also a particular and explicit attention” (Incunda semper).
