This book serves as an introduction to the burgeoning field of ecothology, illustrating both its variety and its commonality across different Christian theological divides. Some of the questions addressed in this short book include the following: How can the Bible still make sense in the context of climate change and biodiversity loss? Who on earth is Jesus Christ, and what does he mean for us in today's world? How can Christians be faithful to their traditions while responding to pressing calls to be engaged in environmental activism? What is the relationship between theory and practice, and local as well as global demands, and how is this relationship expressed in different ecclesial settings? How can we encourage each other to develop a sense of the earth as divine gift? Written in clear, accessible style, this book walks readers through difficult concepts and shows the way different sources in Christian theology have responded to one of the most significant cultural issues of our time.
