The Week of Prayer for Christian Unity is celebrated annually from January 18 (traditional feast of St. Peter) through January 25 (feast of St. Paul). The observance is sponsored by the WORLD COUNCIL OF CHURCHES AND THE PONTIFICAL COUNCIL FOR PROMOTING CHRISTIAN UNITY OF THE CATHOLIC CHURCH. During this week-long observance, and throughout the year, Christians are invited to gather with their Christian neighbors to join in prayer for Christian Unity. Pentecost is also an appropriate time to plan an ecumenical prayer service
Each year, Christian churches and communities in a particular country develop the theme and texts for the Week of Prayer. Material for the 2014 observance was prepared by representatives from different Churches in Canada, brought together at the invitation of the Canadian Centre for Ecumenism and the Prairie Centre for Ecumenism.
The 2014 theme "Has Christ Been Divided? (cf. 1 Corinthians 1:1-17) focuses on Paul's challenge to the Christians in Corinth to know in their hearts and show in their actions that Christ has not been divided. In his call for unity, Paul points us to a way in which we can value and receive the gifts of others even in the midst of our divisions and understand more fully the unity we already have in Christ.
"Now I appeal to you, brothers and sisters, by the name of our Lord Jesus Christ, that all of you should be in agreement and that there should be no divisions among you, but that you should be united in the same mind and the same purpose."
The Office for Ecumenical and Interreligious Affairs of the Archdiocese of Chicago is encouraging all Christians to engage in personal prayer and join local joint observances during the Week of Prayer for Christian Unity.
