Conflict among missionary societies and missioners in Asia and Africa has been a defining feature in the history of missionary work. In 1879/80, German missionary Ernst Faber and three others were expelled from the Rhenish Missionary Society (RMG) due to a leadership dispute over the Canton Central missionary school. This conflict involved RMG inspectors, missionaries and institutional power distribution, differences in dogmatic Lutheran and liberal confession, knowledge perceptions and missionary methods within the colonial context. The expulsion of Faber had a lasting impact on RMG’s missionary course in China. However, there is a research gap concerning the causes and consequences of this conflict. Guided by the theoretical framework of entangled history, this study employs a historical material qualitative research method, drawing on the source An die General-Versammlung der Rheinisch-Westfaelischen Missions-Gesellschaft to analyze the reciprocal competition among the parties involved. It aims to examine this historical event as a microcosm of the entanglement between missionary, church and colonial histories.
