The Holy See and the Question of Sending Observers to the World Conferences of the International Ecumenical Movement

The aim of this paper is to reconstruct the attitude of the Holy See towards the international ecumenical movement during the pontificate of Pius XII, analysing in particular the debates triggered by the question of the participation of Catholic observers in the various international conferences and assemblies of the Faith and Order movement and the constituent Ecumenical Council of Churches. This analysis will be carried out through the study of Vatican documents, in particular from the archives of the Dicastery for the Doctrine of the Faith, the Secretariat of State and the nunciatures, in order to trace the choices and strategies adopted by the Holy See in the face of the challenges posed by the growing importance of the World Council of Churches on the international scene.
