After eight months of itinerant fieldwork across 17 provinces, I elaborate on how the largest Pentecostal group deeply localized in China, the True Jesus Church, has undergone sect‐to‐church movement through interactions among overseas, coastal, and inland churches in globalizing China. A critical intermediary role in this process has been taken by emerging coastal Fujian leaders, who have been successfully reforming not only their churches but also inland counterparts by tactfully utilizing overseas churches as stimuli, resources providers, and legitimizers for the transformation project. The Chinese fever of integration into the world and high status granted to the overseas are keys to smooth away the barriers of the traditionalist old guard. Accordingly, the originally enclosed, anti‐political, sectarian, spirit‐led group has turned more institutionalized, laity‐oriented, text‐based, and welcoming to the government and mainstream Protestantism.
