This article examines how a local Protestant church has become a socially significant and consequential institution within a Hmong community in northern Vietnam. Drawing on ethnographic fieldwork undertaken by the author in Ta Phin, including participant observation in congregational life, attendance at Sunday worship, more than ten in-depth interviews with members of the community, and sustained engagement with two key interlocutors—Pastor Chang A Cang and Ms. Ly Thi May—the article approaches the church not simply as a community of religious faith, but also as an intermediary social institution. It argues that the Ta Phin Protestant Church translates faith into social capital, moral authority into everyday discipline, and congregational life into practical capacities for livelihood support, mutual aid, and community reorganisation. Empirically, the article shows that the church emerged in a context marked by illness, economic insecurity, burdensome ritual obligations, and the search for a renewed moral order. Analytically, it demonstrates how religious resources operate through trust, discipline, brokerage, and moral legitimacy. The case contributes to debates in the anthropology of religion, the anthropology of Christianity, and religion-and-development scholarship by showing how a local church in upland Vietnam can function simultaneously as a moral community, a broker of opportunity, and an important part of the infrastructure of social life.
