Abstract
This article looks at the early ecumenical movement and the difficulties confronting Christian co-operation. It is particularly concerned with co-operation between the Roman and non-Roman churches. It explores how a combination of institutional suspicion, individual prejudice, and political considerations at both the national and international level, exacerbated an already complex and difficult situation caused by deep doctrinal divisions and ancient animosity. In addition to the institutional obstacles to be overcome in realising the ecumenical ideal, its advocates, despite believing in the principle and working selflessly toward its achievement, harboured severe doubts about the inclusion of the Roman Catholic Church which hindered the very task they had set themselves. Insights into this dilemma are provided by the struggle of William Temple, perhaps one of the most well known and respected figures in the ecumenical movement, to overcome his own anti-Roman sentiments and suspicions. Temple's inner conflicts and the influence of external events are key components illustrating the complex amalgam of problems that confronted early ecumenists. Post-war reactions following Temple's death to his efforts to facilitate a wartime approach to Pius XII serve not only to extend the insights, but also to demonstrate further the constraints and limitations imposed by secular as well as ecclesiastical politics.
