This study was conducted with two congregations from two different joining denominations within the United Reformed Church in two post-industrial towns. I spent two years with each congregation as a participant observer, taking part in congregational life and interviewing members for a total of four years. My interest is in the activity that members of these congregations undertake to sustain and change their congregation’s identity. What particularly interested me was how a Reformed cultural identity was sustained, as there is no (...) central body preserving the tradition. In tackling these issues, I explore the interplay of identity with location, community and worship. The recurring tensions drew my attention to the ways identity is renegotiated, which I explore further by engaging with the dynamic metaphor of flow and turbulence. I formulate a concept of belonging by modifying Foucault’s understanding of technology. I go on to explore the way that this technology of belonging is a driver of members’ interaction with the congregational identity. I therefore argue that congregational identity is a recapitulatory process, which engages the members’ understanding of themselves as belonging to the congregation. In doing this I demonstrate the unsettled, contraplex nature of members’ engagement with the congregation’s identity. (shrink)
