The present volume is a shorter edition of Christ in His Mysteries, Dom Columba Marmion's profound reflection on the Mysteries of Christ's birth, death, Resurrection, and Ascension as presented in the Gospels and the Liturgical Year. In Blessed Marmion's words, the mysteries that Jesus lived were lived for us. In them He shows Himself as our model and wills to make Himself one with our souls as Head of the Mystical Body of which we are members. Advent, Christmas, Holy Week, Paschaltide, the feasts of Corpus Christi and the Sacred Heart--following Christ in this way, uniting ourselves to Him, we share more deeply in His Divinity and His Divine life. The Sovereign Pontiff Pius X wrote in his encyclical of November 23rd, 1903, that "e;the active participation of the faithful in the sacred mysteries and in the public and solemn prayers of the Church is the first and indispensable source of the Christian spirit."e; There is no surer way, no more infallible means, of making us one with Christ.
