‘Ye-su-nim’ 예수님 is the Korean word for Jesus, and the title of my ethnographic film on Christian churches in the London Korean community. The title was created on completion of the film and reflects the uncertain future of these churches as Korean-only communities. As second and third generations of migrant Korean congregations are beginning to define themselves as British rather than Korean, the collective cultural identities of these groups are shifting. Informants from all three churches that I encountered stressed the need for Korean churches to open their doors to other communities and to begin to give services in English. For a community that, in my experience, can be closed off in many aspects to outsiders, the changing attitudes and experiences of younger generations are opening the doors of – and for – the Korean community in London. For the churches, reaching outside of the community is seen as a part of their duty as Christians. My film gives an insight into the space and people that create the environments of two Korean churches that differ from one another. They both have the same open-door intentions for the future of the church but one is more successful than the other and attracts a larger congregation.
