This article examines how an indigenous form of evangelicalism became the predominant form of Chinese Protestantism in the United States since 1949. Chinese-American Protestantism was so thoroughly reconstructed by separatist immigrants from the Diaspora and American-born (or American-raised) evangelicals that affiliation with mainline Protestant denominations and organizations is no longer desired. This development has revitalized Chinese-American Protestantism. Indeed, Chinese evangelicalism is one of the fastest-growing religions in China, the Chinese Diaspora, and among Chinese in America. Though the percentage of Chinese Americans affiliated with Christianity is not nearly as high as that of Korean Americans, Chinese-American Protestantism has achieved impressive numeric growth over the past fifty years. Much of this growth can be attributed to the large number of Chinese who have migrated to North America since World War II.
