The History of Christian Theology
Course Overview
Join Professor Cary for an enriching and thought-provoking journey into the fascinating and inspiring world of Christian thought.
Today, the story of Jesus is known the world over. And yet, more than two millennia later, great thinkers and everyday people still struggle to answer questions like: Who was Jesus? Does his salvation apply to everyone? How does one become saved? Over the centuries, these questions have led to fierce debate and produced deep divisions among the faithful. They have driven profound acts of faith and worship, incited war and persecution, contributed to the building of nations, and shaped lives, profoundly influencing some of the greatest thinkers of Western philosophy. To ponder such questions is to understand the very shape of the Western world and to comprehend the remarkable power Christian faith holds in the lives of believers.
Now, you have the opportunity to explore these profound questions and the many responses believers, scholars, and theologians have developed over more than 2,000 years. Through this 36-lecture course, award-winning Professor Phillip Cary of Eastern University reveals the enduring power of the Christian tradition as both an intellectual discipline and a spiritual path.
Through this course, you will gain thought-provoking insights into a set of teachings that changed the world and discover how, by learning about the diverse beliefs and practices within the wider Christian community, you can enrich your own experience of this great faith.
