Theme for 2011:
"One in the apostles’ teaching, fellowship, breaking of bread and prayer." (Acts 2:42-47)

The annual Week of Prayer for Christian Unity (PCU) gives witness to the unity that Jesus asked for when he prayed “that they all may be one” (John 17:21) and focuses on all that Christians of many traditions have in common.

Ever since it was established in 1908, the week has been observed each year from January 18 to January 25 in the northern hemisphere and at Pentecost in the southern hemisphere.
