At least once a year, Christians are reminded of Jesus’ prayer for his disciples that “they may be one so that the world may believe” (see John 17.21).
Congregations and parishes all over the world exchange preachers or arrange special ecumenical celebrations and prayer services. Traditionally the week of prayer is celebrated between 18-25 January, between the feasts of St Peter and St Paul.
In order to prepare for the annual celebration, ecumenical partners in a particular region are invited to produce a basic liturgical text on a biblical theme. Then an international editorial team of WCC and Roman Catholic representatives refines this text to ensure that it can be prayed throughout the world, and to link it with the search for the visible unity of the church.
For the year 2025, the prayers and reflections for the Week of Prayer for Christian Unity were prepared by the brothers and sisters of the monastic community of Bose in northern Italy.
