The Rosary and the Liturgical Year
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.
