Ancient Christian tradition maintained that God authored two books through which God continues to speak to us: the book of Scripture and the book of Nature. The "book of Nature" has been the subject of intense recent interest due to our growing awareness of human dependence on fragile ecosystems and the environmental crises of the past century. This course will begin with an experiential exploration of the spiritual character of Sewanee's natural setting, move to consider the biblical and theological witness to Creation and human responsibility for it, and conclude with the socio-economic implications for the way we live and work in the 21st century.
