Five years of research and writing. More than 1,000 pages. One extraordinary journey into the Heart of Jesus Christ.

Behold This Heart is the largest and most thoroughly researched book ever written on the Sacred Heart of Jesus. Monumental in scope yet deeply personal in its purpose, it brings together Scripture, theology, history, mysticism, Eucharistic devotion, papal teaching, miracles, saints, warfare, national consecrations, family life and personal conversion within one definitive volume.

Beginning with the pierced side of Christ at Calvary, the book traces the mystery of His Heart through the writings of Saint John, the early Church Fathers, the medieval mystics and the great revelations received by Saint Margaret Mary Alacoque at Paray-le-Monial. It examines the relationship between the Sacred Heart and the Eucharist, Divine Mercy, reparation, consecration, the First Fridays and the enthronement of the Sacred Heart in the Christian home.

Its reach extends far beyond the customary history of the devotion. Readers will discover the Sacred Heart carried into battle by soldiers and chaplains, invoked during persecution and revolution, honoured by kings and presidents, enthroned in homes, and solemnly placed at the centre of entire nations. The book investigates extraordinary Eucharistic signs, major shrines, historic artworks, papal documents and the lives of those whose encounters with the Heart of Christ changed the Church and the world.

No significant dimension of the devotion has been left unexplored. Every symbol is examined. Every major historical development is traced. Every essential prayer and practice is explained. The great theological questions are addressed alongside the human realities of suffering, sin, mercy, healing, spiritual warfare, family life and the soul's response to divine love.

Yet Behold This Heart is more than an unparalleled work of research. It is an encounter with Jesus Christ: the God whose Heart was opened for humanity, who remains present in the Eucharist and who continues to call every person into the depths of His love.

This is the complete story of the Sacred Heart-its biblical foundations, its unfolding through history, its power in the life of the Church and its urgent message for the modern world.

Behold the Heart that has loved humanity without reserve.

Now discover everything that Heart has revealed.
