The twentieth century witnessed the remarkable growth of Protestantism in China despite attempts to eradicate religion during the Cultural Revolution. Employing Bruno Latour's actor-network theory (ANT) to analyze three Fuzhou Protestants' life histories, this paper explores how Protestantism gained strength during the Cultural Revolution despite the lack of conventional institutional resources. I argue that Fuzhou Protestantism in this period experienced an intensification of the dual process of disassembly and reassembly. When institutional Protestant Christianity was dissolved, the form of Protestantism that emerged during the Cultural Revolution increasingly enlisted indigenous-and ever more heterogeneous-elements as mediators of action. This reassembled Christian formation withstood the harsh suppression of the Cultural Revolution, but faced challenges in the Reform and Opening period.
