Monsignor George F. Dillon, DD (1836–93) was an Irish Catholic missionary who served as a priest in Australia for many years, where he was also a “Missionary Apostolic” of Pope Pius IX. In 1884, he delivered a series of lectures in Edinburgh on Freemasonry in response to Pope Leo XIII’s call to “tear away the mask of Freemasonry.” These were published as a book in 1885 entitled The War of Antichrist With the Church and Christian Civilization, which was endorsed by Pope Leo.
