The Russian attack on Ukraine on 24 February 2022 shook Christians and churches all over the world. Many of them relied on the well-established diplomatic contacts between the World Council of Churches (WCC) and the Russian Orthodox Church (ROC), which has been a member of the WCC since 1961. This chapter traces the WCC’s failed diplomatic efforts regarding the Ukraine War up to the present. It argues that these efforts have failed, in part, because the Russian war in Ukraine is a classic geopolitical, imperial war in the categories of the nineteenth century, whereas the political and societal role and position of churches have changed in the twenty-first century. In contrast to the WCC, the Conference of European Churches (CEC), which suffered from pastoral paralysis caused by political bipolarity during the Cold War, has undergone a remarkable development since February 2022. While its representatives, like the WCC, initially relied on methods and means of old church diplomacy, they increasingly turned to citizen-level diplomacy, focusing on Christians and churches in Ukraine, and opened spaces for encounter and exchange in recent months. In this foreign policy transformation, one can discern the outlines of a new geopolitics, a diplomacy oriented towards citizens rather than church/state representatives and relations.
