The aim of the conference is to offer an ecumenical perspective on the significance of the First Ecumenical Council of Nicaea, delving into today’s significance of Nicaea, focusing not only on its theological heritage but also on its relevance for ecumenical theological education and ecumenical formation. Theologians, students, and individuals began discussions related to the intersection of Nicaea, ecumenical theological education, and faith and order perspectives in the conference, which is being jointly hosted by the Ecumenical Institute at Bossey and the World Council of Churches (WCC) Commission on Faith and Order. Rev. Dr Kuzipa Nalwamba, WCC programme director for Unity, Mission, and Ecumenical Formation, moderated the opening plenary, introducing the theme “Towards Nicaea 2025: Exploring the council’s ecumenical significance today.” She also explained how the conference signals the commencement of what the WCC has designated as a Special Ecumenical Year, 2025, offering an opportunity to revisit the original impulses that have shaped the common calling as a fellowship of churches. “It was 17 centuries ago—in 325 AD—that the emperor Constantine convened the council,” she said. “As we stand at this historical milestone, we have the unique privilege of reflecting on the lasting impact of the council’s decisions.” In addition to attending plenary sessions such as the opening plenary, conference participants will engage in academic responses and contribute to panel discussions as well. Rev. Dr Benjamin Simon, dean of the Ecumenical Institute at Bossey and director of the WCC Commission on Ecumenical Education and Formation, focused his opening remarks on the Nicene Creed which, he observed, is characterized by the fact that it emphasizes “the one” in every article of faith. “Unity and togetherness are always emphasized,” he said. “The first article begins with the words ‘We believe in one God,’ and it is followed by the second article with the same structure, ‘and in the One Lord Jesus Christ.’ ” All this is followed finally by the confession that we confess with one baptism—“one baptism for the forgiveness of sins,” said Simon. “It is unmistakable that this confession of faith is about unity.” Dr Andrej Jeftić, director of the WCC Commission on Faith and Order, highlighted the significance of the conference for the ongoing work of Faith and Order. “It offers a remarkable opportunity to examine the roots of our shared faith, common history, and our vision for unity,” he said. “Nicaea also engaged with matters of church order, including not least the common celebration of Easter.” The year 2025 includes a common date for the celebration of Easter. WCC general secretary Rev. Prof. Dr Jerry Pillay officially opened the conference, expressing appreciation for the contributions of scholars, theologians, and individuals. Pillay outlined the conference’s objectives: to highlight the ecumenical significance of the decisions and documents issued at Nicaea; to examine the impact of Nicaea on the development of Christian doctrine, self-understanding of the church, ecumenical relations, and interfaith dialogue; and to reflect on ecumenically accountable ways of approaching the outcomes of Nicaea in theological education. He reflected that, within the ecumenical movement, we often talk about visible Christian unity. He also urged those gathered to also focus on today’s challenges for Christian unity. “We cannot sidestep the issues of theology and ecclesiology if we are wanting to experience the fullness of visible Christian unity,” he said. “We are still not able to come and celebrate at the Lord’s table together.” Photo gallery Learn more about the conference "Towards Nicaea 2025: Exploring the Council’s Ecumenical Significance Today" |
