Sacred Ambition, Secular Power: Jesuit Missions and the Rebalancing Authority of the Portuguese Empire, 1540–1759

This article treats the familiar triad “Gold, God, and Glory” as a heuristic to track how commercial, missionary, and reputational aims were configured within overlapping jurisdictions of the Portuguese world. Through three cases—the 1552 clash in Malacca between St. Francis Xavier and Captain D. Álvaro de Ataíde da Gama; the Gama family’s bargaining over offices and revenues; and the 1759 expulsion of the Society of Jesus—it argues that localized, negotiable frictions in the sixteenth century evolved into a structural confrontation by the mid-eighteenth century. Drawing on published Jesuit correspondence and secondary analyses of royal and municipal records, the study shows how missions initially supported metropolitan aims yet increasingly challenged them as Jesuit educational networks and revenue-bearing assets expanded. The Malacca dispute is read as a jurisdictional struggle over diplomatic access and rents, not merely a moral drama. The 1750 Treaty of Madrid and the Guaraní War further politicized perceptions of Jesuit wealth and influence, while the Lisbon-centered reform agenda after 1755 turned tension into rupture.
