This is a beautifully written work of theology, drawing us more deeply into the mystery of the Trinity through the Divine Liturgy. In Part I, Jean Corbon delves into the Mystery of the Liturgy revealed through the life of Christ and the Church. Then, in part II, he unfolds the beauty of the Liturgy Celebrated. Part III reveals "The Liturgy Lived", emphasizing how the Eucharist is an integral part of human daily living, "the mystery of the river of life that streams from the Father and the Lamb ..." (137). Jean Corbon assists the reader by providing a key to liturgical vocabulary; and, this book has only 200 pages.
