In Christendom at the Crossroads, the introductory book in the Westminster History of Christian Thought series, J. A. Sheppard explores the development of Christian theology in the medieval period. Expertly leading readers through the major theological controversies and issues of the era, Sheppard highlights why those particular questions were so important for Christian believers at that time.

Designed particularly for undergraduate courses in theology and religion, the Westminster History of Christian Thought series offers reliable and accessible introductions to Christian thought for each major period in Christian history–the early church, the medieval era, the Reformation, the modern age, and the contemporary period–and concludes with a volume on American religious thought.
