In this masterful exposition of the sacred liturgy, Dom Prosper Guéranger, Abbot of Solesmes and towering figure of the nineteenth-century Catholic revival, unfolds with rare clarity the meaning and purpose of the prayers and ceremonies of the Traditional Latin Mass. Drawing upon the wisdom of the Church’s tradition, he traces each rite to its doctrinal foundations - giving both the historical origins of these venerable practices and their enduring spiritual significance for the faithful. He provides both clergy and laity with an invaluable guide to a fuller and more reverent participation in the supreme act of Catholic worship.
