What can we learn from an ancient Church for a modern world? This book explores our most pressing challenges, drawing on the resources of ancient Christianity. It demonstrates how the Bible, and ancient authors such as Augustine and Athanasius, speak to contemporary issues of environment and restorative justice, racism and education.
