<b>What can contemporary media fandoms, like Anne Rice, Star Wars, Batman, or Sherlock Holmes, tell us about ancient Christianity?</b> Tom de Bruin demonstrates how fandom and fan fiction are both analogous and incongruous with Christian derivative works. The often-disparaging terms applied to Christian apocrypha and pseudepigrapha, such as fakes, forgeries or corruptions, are not sufficient to capture the production, consumption, and value of these writings. De Bruin reimagines a range of early Christian works as fan practices. Exploring these ancient texts in new ways, he takes the reader on a journey from the 'fix-it fic' endings of the Gospel of Mark to the subversive fan fictions of the Testaments of the Twelve Patriarchs, and from the densely populated storyworld of early Christian art to the gatekeeping of Christian orthodoxy. Using theory developed in fan studies, De Bruin revisits fundamental questions about ancient derivative texts: Why where they written? How do they interact with more established texts? In what ways does the consumption of derivative works influence the reception of existing traditions? And how does the community react to these works? This book sheds exciting and new light on ancient Christian literary production, consumption and transmission.
