Rimini: The 1,700th anniversary of the Council of Nicaea, a landmark event in Christian history, has become a rallying point for unity between Catholic and Orthodox Churches. Addressing the anniversary during the Rimini Meeting held from August 22â27, Cardinal Kurt Koch, Prefect of the Vaticanâs Dicastery for Promoting Christian Unity, and Ecumenical Patriarch Bartholomew I of Constantinople underlined the councilâs enduring role in shaping Christian faith and fostering ecumenical dialogue.
Cardinal Koch recalled that the Council of Nicaea, convened in 325 A.D., defended the Church against the Arian controversy by affirming the divinity of Christ. âThe Nicene Creed, proclaiming Christ as âconsubstantial with the Father,â became the foundation of Christian faith across centuries,â he said. He emphasized that unity within the Church can only be restored through fidelity to apostolic faith and the essential truths professed at Nicaea.
Highlighting the ecumenical value of the council, Koch noted that the Nicene Creed is embraced not only by Catholics and Orthodox Christians but also by Reformation-era ecclesial communities. âThe unity of Christians is possible only through a shared confession of faith,â he explained, stressing that prayer has always been the heart of the ecumenical movement. âThe Holy Spirit will guide us to complete the work of unity begun in prayer,â he added.
Patriarch Bartholomew I also stressed the councilâs authority and continuing relevance for the Orthodox Church. He pointed out that the Nicene decisions remain âa cornerstone of Christian proclamationâ and highlighted two pressing contemporary issuesâsynodality and a common date for Easter.
âTo be credible as Christians, we must celebrate the Saviorâs resurrection on the same day,â Bartholomew said. While acknowledging differing sensitivities among Churches, he emphasized that a common Easter date would greatly strengthen Christian witness, particularly for families of mixed traditions. âEaster is the heart of Christianity. To celebrate it together would reaffirm the faith in the Resurrection as the foundation of our hope,â he said.
The Patriarch also underlined the role of synodality in the ecumenical journey, pointing to theological documents that recognize it as a defining characteristic of the Churchâs life and mission. âThe future of ecumenism depends on our ability to walk together synodally, with theological clarity and pastoral prudence. The Council of Nicaea remains a teacher in this regard,â he concluded.
The joint reflections of Cardinal Koch and Patriarch Bartholomew signal renewed momentum in the search for unity between East and West, grounded in the shared faith that the Council of Nicaea articulated 17 centuries ago.
