This concise introduction to the church fathers connects evangelical students and readers to twelve key figures from the early church. Bryan Litfin engages readers with actual people, not just abstract doctrines or impersonal events, to help them understand the fathers as spiritual ancestors in the faith. The first edition has been well received and widely used. This updated and revised edition adds chapters on Ephrem of Syria and Patrick of Ireland. The book requires no previous knowledge of the patristic period and includes original, easy-to-read translations that give a brief taste of each writer's thought.
