A Vietnamese Moses is the story of Philiphê Bỉnh, a Vietnamese Catholic priest who in 1796 traveled from Tonkin to the Portuguese court in Lisbon to persuade its ruler to appoint a bishop for his community of ex-Jesuits. Based on Bỉnh’s surviving writings from his thirty-seven-year exile in Portugal, this book examines how the intersections of global and local Roman Catholic geographies shaped the lives of Vietnamese Christians in the early modern era. The book also argues that Bỉnh’s mission to Portugal and his intense lobbying on behalf of his community reflected the agency of Vietnamese Catholics, who vigorously engaged with church politics in defense of their distinctive Portuguese-Catholic heritage. George E. Dutton demonstrates the ways in which Catholic beliefs, histories, and genealogies transformed how Vietnamese thought about themselves and their place in the world. This sophisticated exploration of Vietnamese engagement with both the Catholic Church and Napoleonic Europe provides a unique perspective on the complex history of early Vietnamese Christianity.
