Y. T. Wu (Wu Yaozong, 1893-1979) is the so-designated key figure of the Christian Three-self Patriotic Movement (TSPM). Before the founding of the People's Republic of China, Wu's discontent with the current conservative Christian theology led him to way of radical identification with communism. Alongside this intellectual struggle and exploration, the relationship between Christianity and communism became the major theme of his theological concern. This paper aims to investigate the theological re-orientation of Wu between 1949 and 1954. For example, in order to restore the revolutionary spirit of Jesus Christ, Wu believed that current Christian theology should undergo a complete and thorough reform. However, Wu's proposal for theological reform aroused strong protests among the conservative and fundamentalist wings of the Christian church. His understanding of the relations of Christianity with communism also contradicted with the policy of the Communist party of China towards Protestant Christianity. To archive the Party-state’s agenda of Christian unity under the TSPM, Wu reluctantly suspended his blueprint of theological reform.
