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). Hearts are touched and Christians come together to pray for their unity. Congregations and parishes all over the world exchange preachers or arrange special ecumenical celebrations and prayer services. The event that touches off this special experience is the Week of Prayer for Christian Unity.

Traditionally celebrated between 18-25 January (in the northern hemisphere) or at Pentecost (in the southern hemisphere), the Week of Prayer enters into congregations and parishes all over the world. Pulpits are exchanged, and special ecumenical worship services are arranged.

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.
