The Week of Prayer for Christian Unity is an international initiative where Christians worldwide are reminded of Jesus’ prayer for his disciples that “they may be one so that the world may believe” (John 17:21). Locally, UniteBoston coordinates evening collaborative gatherings of fellowship, prayer and worship from January 18-25 annually.

This Year’s Theme for the Week of Prayer for Christian Unity: In 2025, Christians mark the 1,700th anniversary of the First Ecumenical Council at Nicaea, where key doctrinal disputes about the Trinity and the nature of Christ were resolved, resulting in the Nicene Creed—a foundational statement of Christian faith and unity. The Nicene Creed is the Christian “symbol” of agreed doctrine and also the statement of faith for UniteBoston. But why does the Nicene Creed matter? Read below to learn about the historical basis of the Nicene Creed and hear a few thoughts by notable theologians and local leaders on its significance as well.

“Within the Empire, particularly between the great apostolic patriarchies of Alexandria and Antioch, disparities in Christology were leading to excommunications and divisions, especially in the rivalry between St. Athanasius and Arius. The common doctrine achieved was a significant milestone in Christian unity. It is only appropriate then, in remembering this event of common confession, that Christians today may celebrate that which unites them. Spiritual ecumenism, according to Vatican II, is the “soul” of the ecumenical movement. It is our common faith in the Risen Christ that brings us together for prayer. In turn, the prayer itself is effective in nourishing and confirming our unity.” – James Loughran, SA, in his reflection on this year’s Week of Prayer for Christian Unity theme

“The use of the phrase “We believe” in the Nicene Creed is so significant. In an area of skepticism and fragmentation, it affirms a shared faith and belonging that faith is not just a private affair, or something that we created today, but is rooted in historical reality of the person of Jesus Christ. It helps to bridge the past to the present and the local Boston Church to the global, reminding us that we are part of something much bigger than ourselves.” – Rev. Kelly Fassett, Executive Director of UniteBoston

“When we recite the Nicene Creed, we are stepping into the stream of a centuries-long conversation about who God is and what God has done. It anchors us in a living tradition of shared understanding and worship.” – Rowan Williams, Former Archbishop of Canterbury

“The Creed expresses what the Church believes, teaches, and confesses in unison. It is the foundation of our unity, the treasure we hold in common, and the proclamation of the hope we have in Christ.” – Pope Benedict XVI

“The Nicene Creed is a confession of the inexhaustible mystery of God’s love. It invites us into the drama of salvation, where the Church stands as a witness to the world of the truth of Christ.” – Hans Urs von Balthasar

““In the Nicene Creed, we encounter the Church’s faithful testimony to the mystery of Christ. It is a gift handed down to us that holds together the Gospel’s integrity and unity.” T.F. Torrance

“This theme, by offering a way to see that faith is not just a static set of beliefs, but an active means of receiving grace, is most appropriate for the Week of Prayer for Christian Unity in 2025. If faith can raise the dead and conquer all fear, surely faith will bring us the miracle of unity as Christians. Remembering that division, separation and rejection are symptoms of sin, the healing of the Church comes about in the power of the Holy Spirit. We pray knowing to whom it is we pray, as one community. God wills us to reconcile. God wills us to love one another. God will give those who profess the faith of Martha, of Nicaea and of all the holy ones who have gone before us, the precious gift of unity.” – James Loughran, SA, in his reflection on this year’s Week of Prayer for Christian Unity theme
