The Feast of Our Lady of Ransom, also known as Our Lady of Mercy, is celebrated on September 24 and honors the Blessed Virgin Mary’s role in the redemption of Christian captives during the Middle Ages. It originated with the foundation of the Order of the Blessed Virgin Mary of Mercy (the Mercedarians) in 1218 by St. Peter Nolasco, with support from St. Raymond of Peñafort and King James I of Aragon, after the Blessed Virgin appeared urging them to ransom Christians enslaved by Moorish raiders. The feast highlights the Blessed Virgin Mary's compassion and intercession, the Christian call to works of mercy, and the hope of liberation—both physical and spiritual—through Christ.

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.
