A major intellectual resource.
Jaroslav Pelikan, from the foreword.

The multiple award-winning Encyclopedia of Christianity (EC), copublished by Brill and Eerdmans, is a monumental five-volume work presenting the history and current state of the Christian faith in its rich spiritual and theological diversity around the world.

Volume 1 (A-D) contains 465 articles featuring
- articles on all but the smallest countries of the world, including the former communist nations that have gained independence since 1989;
- the latest statistical information from David B. Barrett on the religious affiliation and ecclesiastical breakdown of each country and continent;
- articles on doctrines, denominations, and social and ethical issues in relation to the churches;
- biographical articles on prominent figures through church history.
