This comprehensive work explores the deep spiritual and historical connection between the Immaculate Heart of Mary and the Sacred Heart of Jesus. Drawing from Scripture, the Church Fathers, and centuries of theological development, Father Campbell presents a compelling case that devotion to the Two Hearts is not merely optional—it is essential.

At over 1,000 pages, with nearly 700 dedicated to tracing the evolution of this devotion, the book offers an unparalleled survey from early Christian thought through the Middle Ages, into its flourishing in the 17th century, and onward to its growing place in Church teaching and liturgy. 

Saints like John Eudes and Margaret Mary Alacoque, as well as mystics and theologians of the French School and Jesuit tradition, played a key role in shaping this devotion.

Despite its decline after Vatican II, devotion to the Two Hearts saw renewed emphasis under St. John Paul II and his successors. 

With theological depth and historical breadth, this book affirms that, by God’s design, the way to the Heart of Jesus is through the Heart of Mary—two hearts, united in love and mission.
