Nothing is more glorious on this earth or in heaven than the immeasurable sacrifice of the Mass; for it is one and the same as Jesus Christ’s on Calvary, “the Lamb standing as slain from the foundation of the world, the eternal work of the hidden God made present for us. And there is no better guide to this most mysterious trove of grace as The Hidden Treasure: Holy Mass.

Many a Catholic book has been written on the Holy Mass . . . . None, however, conveys the power and all-consuming majesty of the Divine Liturgy of the Eucharistic Sacrifice as well as this great one: The Hidden Treasure.

The author, Saint Leonard of Port Maurice, was a humble Franciscan ascetic renowned as a preacher in his own times, but now almost unknown.

The Saint writes, “It [the Mass] is the sun of Christianity, the soul of the Faith, the centre of the Catholic religion, the grand object of all her rites, ceremonies, and Sacraments; in a word, it is the condensation of all that is good and beautiful in the Church of God.”

Within the pages of this Catholic book, find described the immortal merits of the sacrifice of the Mass, one and the same as Christ’s on Calvary. Learn how the Mass expiates our sins and perfectly satisfies God’s justice, and how it brings endless blessings from heaven (both temporal and spiritual). In addition, learn how to assist reverently and fruitfully at Holy Mass. Finally, as St. Leonard says, “learn to be counted among the priests of the New Covenant by virtue of baptism as our prayers our offered through ordained priests in union with Christ Himself, the Eternal High Priest”.
