2015 Reprint of 1914 Edition. Full Facsimile of the original edition. Not reproduced with Optical Recognition Software. J. Godfrey Raupert, one of the most respected English Catholic authors of the early 20th century, traces in this work the Church’s combat with the powers of darkness from Our Lord’s time, through the age of persecution, into the Middle Ages and the Renaissance, and up to the modern era. Drawing upon New Testament accounts, the witness of the Fathers of the Church, the testimony of such great saints as St. Teresa of Avila and St. John Vianney, and the experience of exorcists he knew personally, Raupert reveals the terrifying power of evil at work in the world.
