This paper puts two bodies of work– the anthropology of Christianity and literature on ‘indigenous cosmopolitics’ – in dialogue by exploring Christianity as a form of political critique and engagement among Bidayuhs in Malaysian Borneo. Drawing on fieldwork on a dam-construction and resettlement project, I examine the imbrication of both God and Christian morality with a group of affected villagers’ long-running struggle to resist the whole scheme. I suggest that far from turning away from the politics of a domineering, developmentalist government, their efforts entail an attempt to reframe the terms of their engagement with the state. At the same time, I consider the implications of these Bidayuhs’ cosmopolitical project for anthropological approaches to difference and pluralism.
