It is important to stress here that the ecclesiology of communion promoted by the Council takes its inspiration from the Eucharistic ecclesiology of the Orthodox, especially Afanassief, who is cited in the texts. The Council\u2019s ecclesiology is thus of great ecumenical import. The intervention of John Zizioulas, the Metropolitan of Pergamon, at the 2005 Roman Synod of Bishops on the Eucharist, testifies to this: \u201cThe ecclesiology of communion promoted by Vatican II and deepened further by eminent Roman Catholic theologians can make sense only if it derives from the eucharistic life of the Church. The Eucharist belongs not simply to the beneesse but to theesseof the Church. The whole life, word and structure of the Church iseucharistic in its very essence.\u201d\u009d Walter Kasper agrees wholeheartedly and holds that \u201ceucharistic ecclesiology has become one of the most important foundations of the ecumenical dialogue between the Catholic Church and the Orthodox Churches.\u201d\u009d<\/p>\n
