Saint Luke the Evangelist, a physician by profession and companion of Saint Paul, was the author of the third Gospel and the Acts of the Apostles. Born a Gentile, likely in Antioch, he was highly educated and wrote in refined Greek, emphasizing Christ’s compassion for sinners, the poor, and the marginalized. His Gospel is noted for its detailed accounts of the Virgin Mary, the infancy of Jesus, and many parables unique to him, such as the Prodigal Son and the Good Samaritan. Luke accompanied Paul on several missionary journeys, sharing in his labors and sufferings, and remained faithful to him until the end. Tradition holds that he also painted the first icons of the Blessed Virgin Mary and that he died a martyr in Greece. His feast is celebrated on October 18.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.Please note: The entries of the Liturgical Year are primarily authored by Dom Prosper Guéranger, but occasionally contain editors’ additions of subsequent information and events that are relevant to the given feast.
