Sigurd Bergmann is professor of religious studies (theology, ethics, and philosophy of religion) at the department of archaeology and religious studies, Norwegian University of Science and Technology, Trondheim, and chair of the European Forum for the Study of Religion and the Environment. His publications include In the Beginning Is the Icon, Visual Arts and Culture, Spaces of Mobility, and Theology in Built Environments.
After critically and constructively summarizing previous initiatives toward an ecological theology, Bergmann opens up an extraordinary dialogue between these initiatives and church father Gregory of Nazianzus. Through the neglected topics of sociality, motion, suffering, and the Spirit, the author brings to light Gregorybs thought on the liberation of creation. Finally, Bergmann connects ecological issues and patristic tradition with contemporary liberation theology.
