The War of Anti-Christ with the Church and Christian Civilization is a book written in 1885 by an Irishman, George F. Dillon, DD. It was republished by Fr. Denis Fahey in 1950 as Grand Orient Freemasonry Unmasked as the Secret Power Behind Communism. The central theme of the book alleges that atheistic Illuminism, through the infrastructure of Grand Orient freemasonry, driven by the ideology of the philosophies laid the foundations for a large scale, ongoing war against Christendom in general and Catholic Church in particular. The document claims that this had been manifested primarily through manipulating the outbreak of various radical liberal republican revolutions. Particularly those focused on atheism or religious indifferentism in their anti-Catholicism. The book details revolutionary activity in France, Italy, Germany and Ireland
Included within the scope of the book is material on the Illuminati, Kabbalism, Jacobinism, the French Revolution, the Carbonari and Fenianism. The Alta Vendita document was given wider exposure in the Anglosphere after being first translated for the book and placed within a historical context. The book was influential to Catholic integralism in Ireland, Britain and the United States, as well as national conservative politics. Fahey who republished the book in the 1950s founded the Maria Duce political movement to fight for an Ireland under the social and spiritual reign of Christ the King. The company who republished it, the Britons Publishing Society, described the book as "of world-wide importance".
