This article offers a broad overview of Christian ecotheology, a theological movement reflecting on Christian responses to ecological destruction. Any such an overview can hardly cover its spread in different geographical contexts, confessional traditions, theological schools, and languages. With these limitations in mind, this entry offers a first approximation of Christian ecotheology on the basis of the Greek roots oikos, theos, and logos, and identifies four core tasks (a dual critical and a dual constructive task) for any form of ecotheology. It then explores various prompts, precursors, and subsequent developments in global Christian ecotheology. The article lists a myriad of current discourses within ecotheology before identifying and outlining a number of ongoing contestations in the field. On this basis, some perspectives on current paths and emerging horizons in the field are offered.
