This book takes the great wisdom of some of the leading exorcists in the Church, including Fr. Chad Ripperger, Fr. Gabriele Amorth, Fr. Jose Antonio Fortea, Fr. Gary Thomas, among others, and packages it into an approachable and intriguing book that conveys, to today's Catholics, critical insights into the activity of the diabolical and spiritual warfare tactics with which we must be familiar. These exorcists pull their teachings from the sacred traditions of our Faith, the teachings of the Fathers and Doctors of the Church, the wisdom of exorcists under whom they were trained, and their own extensive experience in the realm of spiritual warfare, deliverance, and exorcisms.
