Jurisdictional Struggles Between Bishop and Grand Master in Malta in the First Half of the Seventeenth Century

This study examines the jurisdictional disputes between the bishop of Malta and the grand masters of the Order of St John during the first half of the seventeenth century, specifically from 1563 to 1650, in the wake of the Council of Trent. It focuses on conflicts concerning ecclesiastical immunities—personal, real (material), and local—as key points of tension between spiritual and temporal authority in early modern Malta. By analysing extensive archival correspondence preserved in the diocesan archive of Malta between the bishop, the grand master, and the Holy See, the study reconstructs how these immunities were invoked, negotiated, and contested. It employs a historical–legal methodology, interpreting these documents within the wider European context of Tridentine reform and absolutist State building. While established scholarship has highlighted broader patterns of Church–State conflict in early modern Europe, this study contributes an original case from the periphery of Catholic Christendom, where both bishop and grand master were ultimately subject to the papacy. The article is structured around the three traditional forms of ecclesiastical immunity, each examined as a distinct yet interconnected site of struggle. It argues that, in Malta, the application of Tridentine reforms served both to consolidate episcopal authority and to provoke resistance from secular powers, revealing the complex, mediated nature of ecclesiastical governance. The study ultimately sheds light on how canonical tradition, papal intervention, and local political configurations shaped the contested boundaries of sacred and secular jurisdiction.
