The Scourge of Demons: A Classic Manual on Exorcism and Spiritual Warfare

• Definitive 16th-century manual on exorcism and spiritual warfare
• Written by Fr. Girolamo Menghi, known as the “Father of the Exorcist’s Art”
• Newly translated into English by Fr. Robert Nixon, OSB
• Includes a foreword by Fr. Cliff Ermatinger
• Covers practical insights into spiritual combat, temptation, and virtue

For the first time in modern English, The Scourge of Demons brings to light the Church’s most influential manual on exorcism and spiritual warfare, written by Fr. Girolamo Menghi in the 16th century. 

Translated by Fr. Robert Nixon, OSB, and introduced by Fr. Cliff Ermatinger, this classic text remains both accessible and powerfully relevant—firmly grounded in scholastic theology and written in a style that’s comprehensible even to today’s parish priests and lay faithful.

Originally published to great acclaim across Catholic and newly Protestant nations alike, Menghi’s work served as the definitive handbook for exorcists for more than 300 years. But its influence extends beyond exorcists—it offers valuable spiritual insight for any Christian navigating the daily battle between good and evil.

Topics include:

• Discerning between true devotion and dangerous superstition
• The importance of humility as a defense against demonic deception
• The role of sacred music in spiritual fortitude
• How saints powerfully intercede in spiritual combat
• The surprising ways demons turn on each other
• Warnings against curiosity in diabolical matters

And more practical tools for holiness and protection

The Scourge of Demons is both a fascinating historical work and a living resource for those seeking clarity, courage, and Christ-centered strength in the face of spiritual darkness.
