Creating and refining boundaries--church splitting among Pentecostal Vietnamese migrants in Berlin

In many parts of the world, Pentecostalism is becoming the fastest growing religious movement. As a result of migration, people from Asia, Africa and Latin America carry religious ideas and practices across borders, in other cases, migrants establish religious networks in the diaspora. However, while embracing newcomers from various backgrounds, Pentecostal believers constantly cross cultural boundaries by incorporating people from different ethnic, national and language backgrounds. While Pentecostal charismatic practitioners blurr boundaries in many situations, simultaneously, they create 'bright boundaries' by rejecting 'traditional' religious practices, imagined as the Other of Pentecostalism and thus to be eliminated. By referring to the concept of boundaries (Barth 1969; Alba (Ethnic and Racial Studies 1:20-69, 2005)) this article argues that charismatic Pentecostal Christianity, alongside its embracing practices with regard to social, ethnic and political boundaries, generates religious boundaries: First, church members reject "traditional" religious practices such as ancestor veneration and spirit possession, practices migrants carry across borders. Second, Pentecostal believers create boundaries towards those who split from the church. By exploring the ambiguities of migrant converts, I will investigate, how some of them subvert and reject control and authority exerted by religious leaders. Therefore, this article, based on ethnographic fieldwork among Vietnamese Pentecostalists, contributes to widely underresearched practices of boundary making and church splitting in the diaspora.
