In Western ecumenical research, the perception of Orthodox theology still suffers from the stereotype of representing a solidified traditionalism. In contrast, Orthodox theology is dominated by the clichéd notion of Western Christianity as modernism contrary to tradition. This overlooks the many interesting and novel research approaches. On the one hand, these are developed at orthodox institutions worldwide in response to modern scientific questions, and on the other hand they reveal the continuity of the Christian heritage in change in Protestant and Catholic drafts. The series aims to provide a forum for these research approaches and thus enrich the ecumenical discussion with contributions that have been written from a culturally and religiously different background. The series focuses on monographs, but is also open to inter- and transdisciplinary scholarly anthologies. It accepts contributions in German, English and French. All manuscripts are peer-reviewed.
