Kimbanguism, an African Independent Church, has implanted itself in the West since 1975, initially as an association of Congolese students. They found themselves compelled to create their own gathering space to worship according to their traditional forms of belief—worship services, baptisms, religious feasts—, moral guidelines, and identity reference codes. But in almost 50 years of a slow and still incomplete settling down of the Kimbanguist church in Western societies, its modes of integration remain specific to the migratory context. This chapter will thus focus on community modes of expression, specific modes of Kimbanguist integration, problems of adjustment, interracial marriages, and the discrepancy between two systems of value, entailing a generation gap between traditional Kimbanguism and the modes of religious affiliation and beliefs of second- and third-generation Kimbanguists, born or educated in the West.KeywordsKimbanguismAfrican Independent churchKongoKimbanguist diasporaMigrations
