From its very beginning, Christianity was an innovative movement which had to construct and maintain its identity, morality, and social as well as theological boundary markers as it developed from a religion of conversion into a religion of tradition. Early Christianity's sensitivity to 'outsiders' evolved in various ways as circumstances and socio-cultural contexts changed. In this volume scholars from around the world reflect on the dynamic relationship between mission and ethos in the New Testament and Early Christianity, focusing particularly on the sensitivity, or lack thereof, to outsiders, and thereby offering new insights into old questions. Most of the New Testament and several second century books are individually studied by specialists in the field making this book a valuable reference volume on the topic.
