Bridging Faiths and Empires:The Assumptionists and the Mission d’Orient (1863–1923)

This paper examines the Assumptionists’ mission, known as the Mission d’Orient, initiated in 1862 with the aim of uniting the Roman Catholic and Orthodox Churches against the backdrop of a changing political and religious landscape. Despite their aspirations, the mission encountered numerous challenges and obstacles, leading to its ultimate failure. The paper focuses on the Ottoman response to Roman Catholic missions, using the Assumptionists as a case study. It explores the factors contributing to the Mission d’Orient’s failure and scrutinizes the Assumptionists’ efforts to foster unity between the two churches. The study argues that the failure can be attributed to complex power dynamics between the Ottoman Empire and Western powers, resulting in a hostile environment for Christian communities. The Ottoman response encompassed state-level actions driven by political conflicts and the direct targeting of Catholic missions as symbols of Western imperialism. The paper examines historical sources and primary documents to shed light on the challenges faced by the Assumptionists and their impact on interfaith relations and diplomacy during this significant chapter in Christian missions’ history
