Numerous studies regarding citizens' identity and nation-building issues have relegated the analysis of religion, understood as a cultural practice, and its role in the governing of the citizen. However, this article states that religious narrative is still a crucial technology of government to conduct the conduct of citizens. Through the Foucauldian notion of governmentality, I draw together the roles of religious discourses in three historical educational events from Argentinean history. In contrast to the secularization theory that ignores the power of religion in shaping the modern republican citizen, this study demonstrates the extent to which Catholic narratives are still a central technology in governing the Argentinean republican citizen.
