From the middle of the 19th century onwards the number of protestant missionaries in China increased tremendously. The evangelical revival movement played an important role in this development with pioneers like J. Hudson Taylor and his China Inland Mission (CIM) on the frontlines. The Swedish Holiness Union (SHU) decided to join CIM in the northern parts of China were the union established its missionary field in 1890. This essay aims to explore changes in how other religious practices, groups and subjects are constructed within SHU missionary letters from China published 1891-1950. The source material consists of missionary letters published in the Unions own periodical Trons Segrar 1891, 1928 and 1950. By basing the analysis on Laclau’s and Mouffe’s discourse theory the study will explore how different discursive formations change, affirm or undermine each other and how different religious practices, groups and subjects are constructed and characterized within a discursive framework.
