When a group of German Christians was asked in 2014 to prepare materials for the 2017 Week of Prayer for Christian Unity, their choice of a “wall” as a symbol of sin, evil and division explicitly referred to the Berlin Wall.

The German reflections on the power of prayer to bring down walls and the Gospel call to reconciliation were adopted by the World Council of Church’s Faith and Order Commission and the Vatican’s Pontifical Council for Promoting Christian Unity and proposed to Christians worldwide for the Jan. 18-25 octave of prayer.

“The image of the wall is very current today — now more than when they wrote the reflection,” said Father Anthony Currer, who coordinates the Vatican contribution to the week of prayer.

The U.S. political discussion of extending the wall along the border with Mexico, Pope Francis’ frequent admonitions about building bridges rather than walls, the global refugee crisis — all of that makes the powerful symbol of a wall even more potent, said Father Currer, an official at the Council for Promoting Christian Unity.

The expanding symbolism of the wall also shows the kind of dynamic that the World Council of Churches and the Vatican are looking for when they ask one very small group of Christians to try to design prayers and reflections for the global Christian community.

The Faith and Order Commission and the pontifical council alternate identifying communities to choose the Week of Prayer theme, draft a worship service, come up with sub-themes and Bible readings for each day of the octave and describe the ecumenical situation in their local community.

With input from international representatives and then approval from the World Council of Churches and the Vatican, the material is sent around the world.

“We deliberately produce the booklet in a boring format because we do not expect anyone to pray from it directly,” Father Currer said. “It is not a prescribed text because adaptation signifies engagement — it is creative and spiritual.”

The local reflections are meant to be universally accessible and eminently adaptable, he said.

“When you do a Google search for the Week of Prayer you should get material prepared locally,” not just links to the text sent out.

The theme for 2017 is: “Reconciliation — The love of Christ compels us.”

Even before the celebrations began, work was underway to finalize materials for the 2018 Week of Prayer with input from an ecumenical group from the Caribbean, and Churches Together in Indonesia already has been asked to prepare materials for the octave of prayer in 2019. T

The long lead time gives Catholics, Orthodox, Anglicans and Protestants around the world time to translate and adapt the materials to their own local situations, cultures and styles of worship.
