Using many key philosophical concepts based on the work of Alain Badiou, this book outlines the relationship between an event and the emergence of a “truth,” which serves as a helpful organizing principle from which to study the origins of Christianity. Alain Badiou and the Book of Revelation argues that despite what postmodern philosophy says, truths still appear, and their immanent character can be known in the world through a militant subject, one who is willing to declare the consequences of an event that has happened. The second half of the book applies Badiou’s theory of the event to the book of Revelation, a book that draws out radical, even terrifying, consequences from an event “the victory of the Lamb,” particularly in the logic of a new world, and a political body that is to come. Based on several new insights following the completion of Badiou’s “The Immanence of Truths,” the book is a full-length treatment of Badiou’s philosophy to the study of Christian origins and the book of Revelation.
