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 the week of prayer is celebrated between 18-25 January, between the feasts of St Peter and St Paul. In the southern hemisphere, where January is a vacation time, churches often find other days to celebrate it, for example around Pentecost, which is also a symbolic date for unity.

The theme for the week of prayer in 2015 comes from the gospel of John: “Jesus said to her: ‘Give me to drink’”. It was proposed by a group of Brazilian Christians called together by the National Council of Christian Churches of Brazil (CONIC). The biblical gesture of offering water to whomever arrives, as a way of welcoming and sharing, is something that is repeated in all regions of Brazil. The proposed study and meditation on the story of Jesus meeting a Samaritan woman at the well is to help people and communities to realize the dialogical dimension of the project of Jesus, which we call the Kingdom of God.
