A revised, updated edition of this classic work on the Sacred Heart of Jesus.   Dr. Tim O'Donnell examines the doctrinal roots of the devotion to the Sacred Heart in Scripture and in the Apostolic and Patristic ages; charts its growth and development through the Middle Ages; explains the enormous contribution of Saint Margaret Mary Alacoque; and unfolds the teachings of the Papal Magisterium on the Sacred Heart, including Vatican II and John Paul II. The book also includes photographs illustrating the development of the devotion. Devotion to the Sacred Heart is intimately linked to our response in love to the Eucharistic Christ. It lies at the core of Catholic spiritual life and is the key to effective renewal of individuals, the Church and the world. For those who haven't yet lived this devotion--or who want to understand and live it more fully--they will discover its richness and beauty in Heart of the Redeemer. Years of careful research have produced a one volume synthesis of how the devotion to the Heart of Jesus has developed over the centuries. The result is a moving overview of how the love for Jesus Christ has grown in the hearts of the faithful from Calvary to the present day.
