2018 Week of Prayer for Christian Unity

Your right hand, O Lord, glorious in power (cf. Exodus 15:6)

January 18-25 is the annual observance of the Week of Prayer for Christian Unity. The theme chosen for 2019 is "Justice and only justice you shall pursue". Join Christians everywhere in praying “that they may all be one” joining our prayer with that of the Lord Jesus Christ. Begun in 1908, these days have been set aside each year so that Christians the world over may share the prayer of Jesus: “that all may be one... that the world may believe” (John 17:21).

The Week of Prayer for Christian Unity has a history of over 100 years in which Christians around the world have taken part in an octave of prayer for visible Christian unity.  By annually observing the WPCU, Christians move toward the fulfillment of Jesus' prayer at the Last Supper "that they all may be one."  (cf. John 17:21)
