This volume examines the contributions of three contemporary theologians -- Rosemary Radford Ruether, Joseph Sittler, and Jürgen Moltmann -- to the development of Christian ecological theology. Against the charge that the Christian tradition is ecologically bankrupt, the author demonstrates the intellectual and spiritual resources available within Christianity for addressing ecological issues. Of particular interest are Ruether's doctrine of God and her emphasis on ecojustice, Sittler's cosmic Christology and reconception of the relation between nature and grace, and Motlmann's doctrine of the Holy Spirit and argument for social trinitarianism. Beyond evaluating the issues raised by Ruether, Sittler, and Moltmann, the author presents sixteen theses or desiderata for any adequate Christian ecological theology.
