Written by college professors and designed particularly for undergraduate courses in theology and religion, the Westminster Histories of Christian Thought, when completed, will offer 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 conclude with a volume on American religious thought. In this Christendom at the Crossroads, the introductory book in the series, James 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. He uses the Apostles' Creed as the background to show how medieval theology developed, the ways that crucial issues were debated, and the effects those debates had on the Church and Christian belief.
