He sought unity of the church by contending that the Orthodox is the true Church of Christ. This essay elaborates on this theme by exploring Meyendorff’s thought on the Great Schism of 1054, his understanding of the nature of authority in the church and in particular, the primacy of Peter."engCreative Commons Copyright (CC 2.5)Great SchismprimacyfilioquePhotiusFourth CrusadeScholasticismOrigenChristian denominationsOrthodox (Eastern, Oriental)Global Church History and World ChristianityMedieval periodDogmaticsArticle
