While there is extensive scholarship on protestant missions in China prior to 1950 and the emergence of Chinese American protestant churches in the United States during the second half of the 20th Century, there is a limited understanding of the mechanisms that allowed the former to shape the growth of the latter. There is little empirical research on the relationships between the recalled missionaries in China and the Chinese student migrants fleeing to the United States during the McCarthy Era. This case study traces how the social ties formed between a missionary and congregants at the Episcopal Mission of Hankow shaped the emergence of the Chinese Bible Church of Greater Boston. These pre-migration ties significantly shaped the Chinese Christian community in Boston and complicate our understanding of the mechanisms facilitating Boston’s Quiet Revival and Chinese American church planting. More broadly, this case study provides insight into how recalled missionaries can shape immigrant communities.
