The Week of Prayer for Christian Unity is an ecumenical prayer initiative in which all Christian confessions pray together to achieve full unity which is the will of Christ himself.
This initiative was born in the Protestant context in 1908 and celebrated its centenary in 2008. Since 1968, the theme and texts for the prayer have been developed jointly by the Faith and Constitution commission of the World Council of Churches, for Protestants and Orthodox, and by the Pontifical Council for Promoting Christian Unity, for Catholics.
Why is it celebrated from January 18th to 25th?
The traditional date in the northern hemisphere runs from January 18th to 25th, a date proposed in 1908 by Father Paul Wattson, because between the feast of the Chair of Saint Peter and that of the conversion of Saint Paul; it therefore takes on a symbolic meaning.
In the southern hemisphere, where January is a holiday period, churches celebrate the Week of Prayer on other dates, for example at the time of Pentecost (as suggested by the Faith and Constitution movement in 1926), an equally symbolic period for the unity of the Church.
When was she born?
In reality, the first hypothesis of a prayer for the unity of the Churches, forerunner of today’s Week of Prayer, was born in the Protestant context at the end of the 18th century; and in the second half of the nineteenth century a Union of prayer for unity began to spread, supported both by the first Assembly of Anglican bishops in Lambeth (1867) and by Pope Leo XIII (1894), who invited it to be included in the context of the feast of Pentecost. At the beginning of the twentieth century, then, the Ecumenical Patriarch of Constantinople Joachim III wrote the patriarchal and synodal encyclical Irenic letter (1902), in which he invites us to pray for the union of believers in Christ. It will finally be the Reverend Paul Wattson to definitively propose the celebration of the Octave which celebrates it for the first time in Graymoor (New York), from 18 to 25 January, hoping that it will become common practice. In 1926 the Faith and Constitution movement began the publication of Suggestions for the Octave of prayer for Christian unity (Suggestions for an Octave of Prayer for Christian Unity), While in 1935 the abbot Paul Couturier, in France, promotes the Universal week of prayer for Christian unitybased on the prayer for “the unity desired by Christ, with the means desired by him”.
In 1958 Il Center Oecuménique Unité Chrétienne of Lyon (France) begins the preparation of the material for the Week of Prayer in collaboration with the Faith and Constitution commission of the World Council of Churches. In 2008, the first centenary of the Week of Prayer was solemnly celebrated throughout the world with various events, the theme of which “Pray continually!” (1Th 5,17) expressed joy for the hundred years of common prayer and for the results achieved.

How is it celebrated and who chooses the texts?
Currently the Week is celebrated with a general themeand starting from a specifically chosen biblical passage and from a subsidy developed jointly, starting from 1968, by the commission Faith and constitution of the WCC (Protestants and Orthodox) and by Pontifical council for the promotion of Christian unity (Catholics), “ancestor” of the Secretariat for the Union of Christians wanted by John XXIII.
What is the theme chosen for 2026?
The proposed theme for this year is: «The body is one, the Spirit is one, just as the hope to which God has called you is one» taken from a passage from the Letter of Saint Paul to the Ephesians in which the Apostle reminds us that we are all called to live in communion and that, through dialogue, collaboration and common testimony, we can build a united and strong Church, capable of facing the challenges of this time (see Eph 4:1-3) to thus realize the vision of Christ for his Church: a united body, which reflects his glory and his love in the world and is committed to peace, justice, human dignity and the right to homeland.
The subsidy for Week 2026 was developed by International Commission appointed by the Dicastery for Promoting Christian Unity (DPUC) and the Faith and Order Commission (F & C) of the World Council of Churches (CEC) meeting from 13 to 18 October 2024 at the Holy See in Etchmiadzin, Armenia. During the meeting, chaired by the Reverend Dr. Mikie Roberts of the WCC and the Reverend P. Martin Browne, OSB, of the DPUC, representatives of the Armenian Local Group collaborated with the International Commission. On October 17, 2024, the members of the local Group and the International Commission were received in audience by His Holiness Karekin II, Supreme Patriarch and Catholicòs of all Armenians.
The Armenian Apostolic Church is part of the Eastern Orthodox tradition and is dotted with the presence of numerous martyrs. Its theological and liturgical rituals, influenced by ancient Christian customs and Armenian cultural influences, reflect an intense spirituality. It boasts a thriving tradition of ecumenism and is committed to building relationships with other Christian communities. In recent decades it has initiated dialogue with various denominations, including the Catholic, Orthodox and Protestant Churches, seeking common ground with all while preserving its unique heritage. Participation in the World Council of Churches and his relations with the Vatican and other ecumenical bodies show his commitment to Christian unity and progress in mutual understanding.
