Vademecum Peregrini: A Pilgrim's Handbook, prepared by the Latin Mass Society, containing Mass Ordinary, Propers for Pilgrimage Masses, prayers for the Angelus, Rosary, Confession, chants, hymns, and songs, and information about the LMS Pilgrimages to Walsingham. Updated 2025 edition. Features newly set chant and modern notation for many chants and hymns. This booklet is a modest 'monument to tradition', containing the best and most popular prayers, devotions, and hymns, used in Catholic contexts in the 19th and 20th centuries, as well as many prayers and devotions of earlier centuries, and the ancient Latin Mass, which is the task of the present generation to preserve and hand on. The Latin Mass Society, founded in 1965, is dedicated to the traditional Latin liturgy of the Catholic Church, the teachings and practices integral to it, the musical tradition which serves it, and the Latin language in which it is celebrated.
