The Liturgical Year, by Dom Prosper Gueranger, OSB. One of the greatest masterpieces of Catholic literature ever produced. A day by day commentary on all the days of the Church’s liturgical year, incorporating a complete education in Sacred Scripture, Catholic theology and morals, Church history and the lives of the saints, liturgical science, ascetical and mystical theology, and much, much more! Because each volume contains the ordinary of the Mass as well as the Propers, it can be used as one’s missal, and many do exactly that. One of Gerry’s ten favorite works of all time, worth its weight in gold. 15 paperback volumes, republished by Loreto Publications, only $249!
