On 21 November 1964, after a long and laborious process, the Council Fathers approved the decree on ecumenism, “Unitatis Redintegratio” by 2,137 votes to 11. The document, which undoubtedly marked a qualitative leap in the relations between the Catholic Church and the other Churches and ecclesial Communities, continues to represent an indispensable point of reference for the Catholic Church in her commitment to ecumenism.
The Pontifical Council for Promoting Christian Unity will commemorate the 50th anniversary of the promulgation of the decree with two events.
On Thursday, 20 November, in the Basilica of St. Paul Outside-the-Walls, Vespers will be celebrated, open to all, and attended by the members and consultors of this Council and the representatives of the Churches and ecclesial communities present in Rome, to give thanks to God for the fruits already gathered along the path of ecumenism during these last 50 years, and to invoke His blessing for the road that still lies ahead.
On 21 November a meeting will take place in the Great Hall of the Pontifical Gregorian University, during which the Pastors and theologians of the Catholic Church and other Churches and ecclesial communities will reread the Council decree, each from his own point of view, discussing today’s ecumenical challenges and those that await us in the future.
The moderator of the event will be Professor Giovanni Maria Vian, editor of L’Osservatore Romano, and the speakers will be Cardinal Kurt Koch, president of the Pontifical Council for Promoting Christian Unity; Bishop Irinej Bulovic of Backa, the Serb Orthodox Patriarch; Professor Timothy George of the Baptist World Alliance; Fr. William Henn, O.F.M. Cap., of the Pontifical Gregorian University; Teny Pirri Simonian of the Armenian Orthodox Church, Catholicosate of Cilicia; and Friederike Nussel of the Lutheran Church.
The meeting will conclude the Council’s plenary session, which will take place from 18 to 21 November and will focus on the theme: “The aim of ecumenism: principles, opportunities and challenges, fifty years after ‘Unitatis Redintegratio’”.
Fifty years after its promulgation, the dicastery considers it useful to examine how the Council degree continues to inspire the ecumenical efforts of the Catholic Church in a changing landscape.
