Week of Prayer for Christian Unity 2025

Introduction

From January 18 to 25, 2025, Christians from around the world will come together to pray during the Week of Prayer for Christian Unity. This edition is particularly significant as it celebrates the 1700th anniversary of the First Ecumenical Council of Nicaea, a key event in Christian history.

Beyond the celebrations, this week is an opportunity to reflect on the meaning of unity in diversity and to deepen ecumenical dialogue. It invites every Christian to pray, meditate, and act to build bridges between denominations.

Origin and Theme of 2025

The Week of Prayer for Christian Unity dates back to 1908, when it was created by Episcopal pastor Paul Wattson. Since then, it has evolved into a major ecumenical event, supported by the World Council of Churches and the Catholic Church.

In 2025, this week takes on a special historical dimension as it marks the 1700th anniversary of the Council of Nicaea. This council, held in 325 near Constantinople, laid the foundations of the Nicene Creed, a confession of faith that remains a cornerstone for all Christians.

The prayers and reflections for this year have been prepared by the brothers and sisters of the monastic community of Bose, located in Italy. The central biblical text for 2025 is taken from John 11:17-27, where Jesus asks Martha: “Do you believe this?”. This dialogue about resurrection and faith embodies the heart of this week, inviting Christians to renew their commitment to a shared faith.

Why is this week essential?

Since its origins, Christianity has been marked by theological, cultural, and historical divisions. These separations have often led to misunderstandings and tensions between denominations. However, at the heart of the Gospel lies a powerful call to unity: \"That they may all be one, as you, Father, are in me, and I in you\" (John 17:21).

The Week of Prayer for Christian Unity is a direct response to this call. It reminds us that despite our differences, we share a common faith in Jesus Christ. It also provides a platform for ecumenical dialogue, enabling believers to draw closer through prayer, studying the Word, and concrete actions.

In 2025, the theme “Do you believe this?” invites every Christian to reflect on the depth of their faith and how it can inspire acts of reconciliation. This reflection is particularly meaningful in today’s context, where the world needs unity and hope more than ever.

How to participate in the Week of Prayer for Christian Unity?

Participating in this week doesn’t require much—just an open heart and a willingness to engage. Here are some ideas to fully experience this event:
