Uniquely authoritative and wide-ranging in its scope and an indispensable reference work on all aspects of the Christian Church. It contains over 6,000 A-Z entries, and offers unrivalled coverage of all aspects of this vast and often complex subject, from theology; churches and denominations; patristic scholarship; and the bible; to the church calendar and its organization; popes; archbishops; saints; and mystics.

Also published under the title The New Westminster Dictionary of Church History, this work is very comparable to the Oxford Dictionary (above). Only volume 1 (early church to 1700) has been published so far.
