This year’s theme for the Week of Prayer for Christian Unity is “Do you believe?” (John 11:26). 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 insights from local leaders and notable theologians on its significance for today.
Click above to watch a reflection on the significance of the Nicene Creed from Dr. Elizabeth M. Woodard, Catholic theologian, musician, author, speaker, spiritual director, and ecumenist. She is a member of our Christian unity cohort and pastoral associate a Sacred Hearts Parish. She considers her vocation as bringing people to God and to each other.
“The Nicene Creed stands as a centuries-old treasure linking current Christians to the earliest ones. It is through symbols like the Creed that we can truly claim to be apostolic, that is, the Church handed to the apostles and handed down from them through generations of Christians. The Creed acts as a barrier against our human temptation to remake God in our own image, and leads us to open ourselves to the wisdom of God’s self revelation, distilled in these precious words throughout our history. Diverse though Christians are in our various traditions, we find a precious unity in our acceptance of the essentials spoken in the Creed.” – Dr. Elizabeth M. Woodard
“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 celebration of any anniversary is, beyond a mere commemoration of an historical event, a motivation to learn from the past in order to live more fully in the present. As Christians united in our faith in a God who assumed flesh and dwelt among us, we have also confessed with one voice the same creed formulated 1700 years ago at the Council of Nicaea. Through the centuries, we may have differed in our interpretations and manifestations of that original statement of faith. Nevertheless, we have endured in our appreciation of and devotion to that earliest of professions and convictions that “we believe in one God, maker of heaven and earth; and in one Lord Jesus Christ, who was incarnate for our salvation. Our unity in this doctrine should inspire us to imagine and illustrate the same faith in language that addresses the challenges of our age and our world. That’s why Orthodox Christians refer to the creed as a ‘symbol of faith.’ Our vocation as Christians is to unravel and unveil, to define and defend the same pristine principles in a way that embraces and heals every human being without discrimination and every aspect of God’s creation without exception.” – Fr. John Chryssavgis, Executive Director of the Huffington Ecumenical Institute
“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

For centuries, the Nicene Creed was sung as part of the Latin Roman Catholic liturgy. Along with many other parts of the Mass “ordinary,” it was set to music by composers throughout the centuries and regularly sung each week. Here, please enjoy an early version set in Gregorian Chant. While most Catholics since the 1960s speak many of the ordinary parts of the Mass, including the Creed, its sung version is a beautiful way to reflect on the words, if you happen to speak Latin!” above to listen to a beautiful singing of the Nicene creed chanted in Latin.

“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
