His All-Holiness Ecumenical Patriarch Bartholomew, in a video message, expressed affection for the institute, recalling his own studies there. “Since October 1946, the Chateau de Bossey has welcomed students from every Christian tradition and from every corner of the world,” he said. “It is fitting therefore that this anniversary should be marked by the gathering of Bossey’s alumnae and alumni, for they are the truest measure of what these 80 years have accomplished.” Cardinal Kurt Koch, prefect of the Dicastery for Promoting Christian Unity, in a written greeting, noted that the history of Bossey is closely interwoven with the deepening relationship between the Catholic Church and the World Council of Churches. “The establishment of the Joint Working Group in 1965, the first meeting of which was held at Bossey in May 1965, opened a new and enduring chapter of dialogue and practical cooperation,” he wrote. “Bossey soon became one of its particularly fruitful expressions.” H.E. Metropolitan Anthony, chairman of the Department for External Church Relations of the Moscow Patriarchate, in a written greeting, reflected that a number of Russian Orthodox Church representatives have gained invaluable experience of inter-Christian dialogue at Bossey. “I would also like to mention high academic standards maintained by the Ecumenical Institute at Bossey, which implements its educational programs in collaboration with the University of Geneva,” he wrote. “On this memorable occasion, I wish you God's help and blessed success in your further ministry.” Most Rev. Dr Olav Fykse Tveit, presiding bishop of the Church of Norway, expressed deep thanks for all that Bossey represents and continues to offer as a place of study and reflection, a space where people from different traditions and backgrounds come together in dialogue, and a living symbol of the ecumenical movement. “Over the years, Bossey has been much more than an academic institution,” said Tveit. “It has been a place of encounter, friendship, learning, and transformation—a place where differences can be explored with openness and respect, and where the shared calling to build greater understanding and unity can take root.” Video message by HAH Ecumenical Patriarch Bartholomew Cardinal Kurt Koch message on the occasion of the 80th anniversary of Bossey Metropolitan Anthony message on the occasion of the 80th anniversary of Bossey The Most Reverend Dr Olav Fykse Tveit message on thew occasion of the 80th anniversary of Bossey Bossey’s 80th celebration reiterates “counter-cultural witness to the kingdom of the God of life” (WCC news release, 7 October 2026) Photo gallery Learn more about the 80th anniversary of Bossey |
