How did the Christian church become what it is today? How did a tiny splinter group of Judaism in the First Century A.D. become the dominant religion in the world 2,000 years later? One way to examine these questions is through a look at key events in the history of the church. This book will provide such a framework for attempting to answer those questions. Pentecost is the traditional beginning of the Christian Church, so that is #1. We'll examine that and 24 more important events, including the "Conversion of Constantine," "Luther Sparks the Protestant Reformation," "St. Augustine Establishes Core Roman Catholic Beliefs," and "Revival Movements in the United States." This edition contains 20 photos, 12 of which are in color.
