There are numerous reference volumes dealing with Christianity. Remarkably, however, until now there has been no one-volume encyclopedia dedicated Christianity on a global scale.This exhaustive work presupposes no prior knowledge of Christianity, and can usefully be consulted by Jews and Muslims, people of other faiths or no faith at all. It covers all forms of Christianity throughout history and the world. Over 300 major articles by distinguished international contributors are linked through a novel series of pointers that provide different angles on topics and show the connections between them. The contributors include the leading experts on the topics under consideration, which range from regional surveys to portraits of denominations and sects, explorations of theological and moral questions, relationships with other faiths, and a "Who's Who" of Christianity. In addition to the main articles, helpful "fact boxes" present basic factual material, often in the form of lists, bringing together information that is often surprisingly difficult to find: creeds, councils, popes, miracles and parables of Jesus, religious orders, and much more. This remarkable resource, more than ten years in the making, fills a major gap in the literature on world Christianity.
