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 by examining key individuals in the history of the church. This book will look at 25 of the most influential people in the post-apostolic history of Christianity. Most of the ones who made the list had a positive impact, but one tarnished the reputation of Christianity for hundreds of years. Among the names on the list: Augustine, Athanasius, Calvin, Torquemada, and Pope John Paul II. This edition contains 23 photos, with 10 of them in color.
