The Week of Prayer for Christian Unity is usually held in the third week of January. In 2015 it's 18 - 25th January. The theme is The Well is Deep.
It's a reminder for churches of different traditions and cultures, not just locally but worldwide, to commit themselves to pray for Christians across the world, that even though we have differences we might remember our unity in Christ. The links on this page offer some resources for use with children and young people.
