More than 400 million persons are living in a state of permanent diaspora throughoutthe world. These dislocated persons are particularly susceptible to receptivity to the Christian message and, being scattered as transnationalsoutside traditional homelands, to finding their identity in the church. Most of these persons hail from the Global South and East, where an explosive growth of Christian communities is occurring within the context of revitalization. Communities in the Global North, including the United States, are meanwhile being remapped with the influx of transnational persons. The multiplication of Hispanic and Asian churches has become the major feature of church growth in a North American Christianity, with its rapidly declining mainline denominational church bodies. This book presents six cases of current revitalization movements amidst diaspora followed by a group of interpretative essays.
