Christians across the globe are preparing to join in the Week of Prayer for Christian Unity, described as the "largest prayer gathering in the world".

The week, which runs from 18th to 25th January, is this year being held under the theme 'Justice, and only justice, you shall pursue', which is inspired by verses in Deuteronomy 16:18-20 which speaks of justice and treating people fairly.

The week, which has been marked for more than a century, is jointly organised by the World Council of Churches and the Catholic Churches' Pontifical Council for Promoting Christian Unity.

Rev Dr Olav Fykse Tveit, general secretary of the WCC, said that as people gather to pray together they will share a sense of joy, concern and accountability, all of which lies at the heart of the ecumenical movement.

“As we celebrate a unity in diversity, we become more able to strongly pursue justice in our many contexts,” he said in a statement. “In all cultures and continents, we can pray for each other and pray together as a living fellowship for justice and peace.”

This year, churches in Indonesia have been invited by the WCC and PCPCU to prepare resources for the week. They can be accessed at www.oikoumene.org/en/resources/week-of-prayer/week-of-prayer.
