The Encyclopedia of Christianity is a monumental reference work that addresses the broad interest in Christianity and religion around the world today. Comprehensive, up to date, of high standard, and easily understandable, the EC describes the Christian faith and community in their myriad forms today and throughout the 2,000 years of Christian history. The EC also looks outward beyond Christianity, considering other world religions and philosophies as it paints the overall religious and sociocultural picture in which the Christian church now finds itself in the new millennium.

Written by leading scholars from many countries and cultural backgrounds, the more than 1,700 articles in the complete EC depict Christianity in its global context. Separate articles for every continent and over 170 countries examine both the history and the current situation of the Christian faith worldwide. The EC also portrays Christianity in its widest ecumenical context. Major articles detail Christianity's rich spiritual and theological diversity in order to inform readers about religious traditions and perspectives beyond their own ecclesiastical frameworks.

In its portrayal of Christianity, the EC also takes into account the current sociocultural context, including other world religions, secular philosophies, cultural trends, and modern political and economic forces. Covering such current topics as abortion, atheism, Islam, modernity, and psychoanalysis, these articles describe the multifarious settings in which the Christian church today must maintain a credible witness to the ancient gospel. Finally, the EC presents Christianity in its rich historical context, examining biblical tradition, apostolic tradition, and how the church has kept these traditions within an ever-transitioning world.
