Roman Catholicism, Diplomacy, and the European Communities, 1958-1964

This article investigates the Roman Catholic Church's role in the process of European integration from the first Hallstein Commission in 1958 to the failure of the Holy See's application to establish a diplomatic representation at the European Economic Community in 1964. The article focuses on the Church's response toward emerging European institutions and shows that local mobilization in Luxembourg, Strasbourg, and Brussels was instrumental in shaping relations between the Catholic Church and the European Communities (EC). The Church's position toward the EC, placing local communities as prime actors in dialogue with European institutions, reflected the sensitive nature of religion during the Cold War.
