Medieval Heresy and the Inquisition: How the Vatican Got Away with the Murders of Millions of Innocent People

Arthur S. Turberville details the Vaticans doctrine underlying the violent Roman Inquisition which was used to suppress all opponents to the Roman Catholic Churchs well-established religion. This book is not a detailed history of the Inquisition but rather an excellent survey of literature on the Churchs doctrines on this practice.
