The relationship between Christianity and Communism is a significant topic in the realm of Christian intellectual history in China. Since the founding of the People's Republic of China (PRC) in 1949, communism becomes absolute and dominates the ideological discourse of the new era. Under this circumstance, Christianity, being critiqued severely as the tool of western imperialist invasion by the new reign, was totally disqualified for further dialogues with the official ideology. This article studies how Y. T. Wu attempted to reconcile Christianity with communism in such a circumstance that Christianity had already lost its legitimate voices in the public sphere. On the one hand, his reflection is a continuous effort to address the issue from a mutually critical approach for more than two decades. On the other hand, Wu's theological reorientation is also a conscious response to the new political context after the founding of the Communist reign. Being the key figure of the Christian Three-Self Patriotic Movement, how did Wu approach the relationship between Christianity and communism? What is the tension between his theological reorientation and the new political situation? This article will help us not only to have a comprehensive and critical understanding of this controversial Christian leader in the light of the state-church dynamic, but also contributes to reconstruct an important piece in the lost history of the early PRC.
