Abstract: In recent years the field of diaspora missiology has been developing within mission studies, receiving important recognition at the Third Lausanne Congress on World Evangelization in 2010. This is an interdisciplinary field of study, bringing together the trialogue of theology, anthropology, and mission. This article explores how the longstanding interest within the discipline of anthropology in the study of migration has evolved since the 1990s into the study of diasporas and transnationalism. The author then presents ways in which this focus in anthropology can assist in the research and study of diaspora missiology. He concludes by discussing ways in which the study of diasporas and Christianity can bring together both anthropologists and missiologists in a cooperative effort to research the sociocultural dynamics at work in understanding this phenomenon, thereby lessening the traditional animosity between these two disciplines.
