For the First time, this monumental work in presented entirely in English. Before you lies, perhaps, the greatest effort in combating Christian heresies. The "History of Heresies" was first published in 1751 and was well-received by the Church hierarchy. The book covers the major heresies that have arisen throughout Christian history, from Gnosticism and Montanism in the early Church to Jansenism and Quietism in the 17th and 18th centuries. In the "History of Heresies," St. Alphonsus provides a detailed and thorough account of each heresy, including its origins, key figures, and beliefs. He also offers a clear and concise refutation of each heresy, using scripture and tradition to defend the teachings of the Catholic Church.
