Paul Chang’s professional interests encompass new, non-Western forms of Christianity, especially from the 19th century to the present. He attempts to understand these novel, unfamiliar movements as part of the longer tradition of Christian thought. His specific area of expertise is Chinese Christianity, which has seen rapid growth from an almost negligible number of Chinese Christians less than fifty years ago to as many as 80-100 million today. Chang’s research explores this startling phenomenon by examining it in multiple contexts: China’s own religious, social, and political history, the larger contemporary trend of rising Christian adherence and dynamism in Africa, Asia, and Latin America, and the general history of Christianity. His current project focuses on two Chinese ministers, Watchman Nee (1903-1972) and Witness Lee (1905-1997) who are related to a number of vibrant Chinese Christian movements. Their ideas and practices have also proven to be extremely appealing outside of China and the Chinese diaspora, forming the basis for thousands of local congregations with indigenous leadership on all six continents.
