As the Catechism of the Catholic Church instructs: Liturgical catechesis aims to initiate people into the mystery of Christ ("It is mystagogy.") by proceeding from the visible to the invisible, from the sign to the thing signified, from the "sacraments" to the "mysteries." Drawing on the above instruction, the unifying theme of Our Sacramental Life: Living and Worshiping in Christ is centered in an emphasis on mystery and mystagogy. In exploring sacramental life, as communicating the mystery of God, the inaccessible and incomprehensible are both made accessible and comprehensible for teenage students. Using Our Sacramental Life: Living and Worshiping in Christ, students will gain a greater appreciation that through the sacramental life of the church: we are given a "language" which enables us to participate in the life of the Trinity, making it possible for us to communicate the mystery of God, and thus to participate in Christ's work of restoring and renewing the world.Driedger, Patricia Morrison is the author of 'Our Sacramental Life Living and Worshiping in Christ' with ISBN 9780877937197 and ISBN 0877937192.
