Beginnings
The Week of Prayer for Christian Unity began in 1908 as the Octave of Christian Unity, and focused on prayer for church unity. The dates of the week were proposed by Father
Paul Wattson, co-founder of the
Graymoor Franciscan Friars. He conceived of the week beginning with the
Feast of the Chair of Saint Peter, which was then kept on the
General Roman Calendar

on January 18 - the same day that the Anglican Church kept the
Feast of the Confession of Saint Peter - and concluding with the
Feast of the Conversion of Saint Paul on January 25.
In 1960 Pope John XXIII removed from the General Roman Calendar the January 18th feast of the Chair of Peter, along with seven other feast days that were second feasts of a single saint or mystery and merged it with the Feast of the Chair of St. Peter at Antioch, kept on February 22. This calendar was incorporated in the 1962 Roman Missal. Hence, only those Catholics who still retain the
General Roman Calendar of 1954 keep the January 18th Feast, although the date continued to serve as the beginning for the Unity Octave. The Feast of the Confession of Peter continues to be observed by Anglican churches on January 18.

Pope
Pius X
Pope Pius X (; born Giuseppe Melchiorre Sarto; 2 June 1835 – 20 August 1914) was head of the Catholic Church from 4 August 1903 to his death in August 1914. Pius X is known for vigorously opposing Modernism in the Catholic Church, modern ...
officially blessed the concept, and
Benedict XV "encouraged its observance throughout the entire Roman Catholic Church." For a while, the observance was renamed the "Chair of Unity Octave" by Wattson, in order to emphasize the relationship between Christian unity and the Petrine See (''i.e.'', the

Evolution
Abbé
Paul Couturier of Lyons, France, who has been called "the father of spiritual ecumenism", had a slightly different approach from that of Father Wattson, a convert to Roman Catholicism from

. He advocated prayer "for the unity of the Church as Christ wills it, and in accordance with the means he wills", thereby enabling other Christians with differing views of the Petrine ministry to join in the prayer. In 1935, he proposed naming the observance "Universal Week of Prayer for Christian Unity", a proposal accepted by the Catholic Church in 1966. Father Couturier's message influenced a Sardinian nun,
Blessed Sister Maria Gabriella of Unity, whose deep, prayerful, sacrificial devotion to the cause of unity is held up by Rome as an example to be followed.
In 1941, the Faith and Order Conference changed the date for observing the week of unity prayer to that observed by Catholics. In 1948, with the founding of the

in 1894),
which is also a symbolic date for the unity of the church.
The 2008 Week of Prayer for Christian Unity was celebrated as the centennial. For 2012, was chosen with the theme "We will all be changed".
The 2016 Week was provided by the Churches of Latvia, and the theme was that all Christians are 'Called to proclaim the mighty acts of the Lord' (indirectly referring to ).
The theme for the week of prayer in 2019, "Justice, and only justice, you shall pursue ..." was inspired by Deuteronomy 16:18-20.
The 2024 week of prayer draws together churches across the globe under the theme "You shall love the Lord your God ... and your neighbour as yourself" (Luke 10:27) with materials prepared by an ecumenical team from Burkina Faso, facilitated by the local Chemin Neuf Community (CCN).
