The Feast of the Most Holy Name of Mary, celebrated on September 12 on the Fifth day within the Octave of the Nativity of the Virgin Mary, honors the name of the Blessed Virgin as a source of grace, protection, and devotion for Christians. Instituted in Spain in 1513 and extended to the universal Church by Pope Innocent XI in 1683 after the victory of Christian forces at the Battle of Vienna, the feast commemorates Mary’s intercession in safeguarding the faithful against danger. The liturgy highlights the reverence due to her name, which evokes her role as Mother of God, helper of Christians, and mediator of divine mercy, encouraging the faithful to call upon her with love and trust in times of need.Dom Prosper Guéranger's The Liturgical Year, a monumental fifteen-volume work, offers a comprehensive exploration of the Catholic Church’s liturgical calendar, guiding readers through the spiritual and historical richness of the Church’s worship. Written in the 19th century, the series provides daily meditations, historical context, and liturgical texts for the Mass and Divine Office, covering the entire cycle of seasons—Advent, Christmas, Lent, Passiontide, Easter, and the Time after Pentecost—as well as feast days of saints. Guéranger’s work, rooted in a deep contemplative spirit, aims to immerse the faithful in the Church’s prayerful life, emphasizing the unity of faith through the axiom lex orandi, lex credendi ("the law of prayer is the law of belief"), and remains a cherished resource for Catholics seeking to deepen their spiritual lives. Dom Prosper Guéranger (1805–1875) was a French Benedictine monk, liturgical scholar, and founder of the Solesmes Abbey, renowned for his pivotal role in reviving the Benedictine Order in France and restoring the Roman liturgy after the disruptions of the French Revolution. Born in Sablé-sur-Sarthe, he entered the priesthood in 1827 and, inspired by a vision to restore monastic life, reestablished the Benedictine community at Solesmes in 1833, becoming its first abbot. A staunch defender of ultramontanism and traditional Catholic worship, he also championed the revival of Gregorian chant, significantly influencing the liturgical renewal movement.
