Alongside development cooperation and humanitarian aid, church cooperation is the third pillar of HEKS/EPER's international work. For decades in some cases, HEKS/EPER has been supporting, advising, promoting and accompanying Reformed Churches in Eastern Europe, Italy and the Near East in their diaconal work and in building up vibrant church communities. HEKS/EPER supports various church-run social activities, especially for children and young people. In addition, HEKS/EPER is ensuring the continued existence of active church parishes through financial and logistical support for the renovation of run-down church buildings. Lastly, through church parish partnerships as well as exchange and continuing education programmes, HEKS/EPER promotes dialogue between Reformed Church parishes in Switzerland and partner churches abroad.
