The Power of the Rosary
by Gabriel Castillo (Gabi After Hours youtube Channel)
The Power of the Rosary, by Gabriel Castillo, is more than a book: It is a theological bombshell, a detonator for spiritual renewal, and a lifeline for modern Catholics who feel lost in the storm. At once mystical, scholarly, and deeply personal, this work deserves to be placed alongside the classics of Marian devotion. It is The Secret of the Rosary for a new generation—expanded, clarified, and intensified.
From the very first pages, Castillo makes clear that the Rosary is not a sentimental string of beads for the weak but a divine weapon forged by the Queen of Heaven and designed to sanctify, deliver, and transform. With the precision of a scholar and the urgency of a preacher, he traces the Rosary’s roots from Sacred Scripture and the Gospels, through St. Dominic and Bl. Alan de la Roche, to Lourdes, Fatima, and the towering figure of St. John Paul II. Every chapter is saturated with insights from the greatest saints, grounded in tradition, and supported by the lived witness of souls who have been changed by Mary’s intercession.
Yet what makes this book shine is not just its doctrinal clarity but its deep intimacy. Castillo writes as one who has been saved by the Rosary. He speaks not just to minds but to hearts—to the young who are searching for purpose, to sinners trapped in mortal sin, to heartbroken parents, exhausted priests, and lukewarm souls in need of fire. His voice is bold but fatherly, convicting but compassionate.
Particularly illuminating is his teaching on mental prayer—how to truly pray the Rosary, and pray it well, using the method of the saints. He combines Carmelite mysticism with Dominican structure. It is here that mystical theology becomes tangible. Readers are not just invited to recite prayers but to encounter Christ face-to-face through Mary, to gaze into the eyes of Jesus in the mysteries of the Rosary, and to converse with God from the heart.
With clarity and conviction, Castillo reveals:
- The true goal of the spiritual life and how the Rosary leads you there
- Why the Rosary is not just piety but theological genius and divine power
- The forgotten role of mental prayer and how to do it simply in the Rosary
- The signs of spiritual warfare in your life and the way to use the Rosary to overcome every obstacle
- How to discern what role the Rosary should play in your life
- How to successfully implement the Family Rosary and share it with others
- How to pray with fire, conviction, and constancy—even in dryness and distraction
This book will pierce you. It will awaken you. It will challenge you to live differently. If you are willing to take up your beads and go to war with Mary at your side, you will not only change your life; you will help save the world, one bead at a time.
Endorsements
“The Second Vatican Council reminds us of the consensus fidei, ‘the consensus of belief’: the fact that the entire Church—the hierarchy, the religious and the laity, past and present—is called upon to provide a bold witness to the truth and to the transforming power of faith in Jesus Christ. In this book, Gabriel Castillo has dramatically illustrated this aspect of our belief by his own witness—and that of the saints, clergy, and lay people—to the overwhelming power of the Rosary to transform lives and to deepen love for our Savior, Jesus Christ, and His mother, Mary.”
