Call for Papers: Nicea and the Church of the Third Millennium

Towards Catholic-Orthodox Unity
International Conference

4. - 8. Juni 2025

The Council of Nicaea (325) is foundational for Orthodox-Catholic unity. The Council inaugurated a synodal way of addressing theological and canonical issues at the universal level. The Nicene Creed provided a theological vision of the triune God that continues to guide the common faith of Christians, in particular, of the Orthodox and Catholic Churches. The conference will focus on uniting and dividing theological and ecclesiological issues by discussing the legacy of the First Ecumenical Council.
