In order to carry forward the spiritual accompaniment of the Korean peninsula and the churches of North and South Korea the WCC is invited to join the Christians of North and South Korea in a joint moment of prayer. Each year, the National Council of Churches in Korea and the Korean Christian Federation jointly prepare a Prayer for Peace and Reunification of the Korean Peninsula. This prayer is used on the Sunday just before 15 August of each year, the day when Korea was liberated from Japanese colonial oppression, and ironically, the day when it was divided by external forces.
