This volume offers an introduction to all questions of teaching Religious Education as a school subject and as an academic discipline related to this subject. The chapters cover most of the aspects that religion teachers have to face in their work, as well as the theoretical background necessary for this task. The volume is a textbook for students and teachers of religious education, be it in school or in an academic context, who are looking for reliable information on this field. The book has proven its usefulness in German speaking countries. This volume is the English translation of the German Compendium of Religious Education (edited by Gottfried Adam and Rainer Lachmann). The present English version is based on the 2012 edition which aims for a most current representation of the field. The background of the book is Protestant but its outlook is clearly ecumenical, and questions of interreligious education are considered in many of the chapters. The compendium continues to be widely used in Germany, Austria and Switzerland -- as an introduction to the field and as a handbook for students who are preparing for their final exams.The English edition makes this compendium available to students and colleagues in other countries.
