Book excerpt: The introduction of Christianity into traditional societies has been the subject of numerous studies. Few of these studies, however, have adequately examined the way that this introduction affects power relationships in a community. In this, the third volume in the American Society of Missiology's dissertation series, A. Sue Russell attempts to advance the discourse on Christianity and social change by showing how a new social institution, the local church, both influences and is influenced by existing sociocultural power relationships. Building on her extensive research into the Tagal Murut, Dr. Russell clearly demonstrates that the introduction of Christianity created a dynamic that produced new social relations and power structures in Tagal society. With its unique insights into this crucial dynamic, Conversion, Identity, and Power stands as an important contribution to the sociological and missiological literature exploring the impact of Christianity on traditional societies.
