Conference of European Churches
The Conference of European Churches (CEC) was founded in 1959 to promote reconciliation, dialogue and friendship between the churches of Europe at a time of growing Cold War political tensions and divisions. It is an ecumenical fellowship of Christian churches in Europe; its membership consists of most of Europe's mainstream Protestant, Orthodox, Anglican and Old Catholic Churches. In 2005, CEC had 125 member churches. A major project, completed in 2001, was the production of the Charta Oecumenica of Europe's churches.
CEC assemblies take place once every six years. The 4th CEC assembly (1964) had to be held on a ship on the Baltic Sea owing to the difficulties of obtaining visas for delegates from eastern European countries.

Between assemblies, CEC was until 2013 governed by a Central Committee meeting annually. The 12th Assembly of the Conference of European Churches (Trondheim, 2003) elected the 40-member Committee. This Committee, according to the CEC Constitution, was "empowered to conduct the business of the Conference when the Assembly is not meeting". At the 14th CEC Assembly (Budapest 2013) the Central Committee was replaced by a 20 member Governing Board. The Governing Board meets twice annually to oversee the implemetation of the decisions of the Assembly. (art. 6.1) Recent meetings of the Central Committee took place in Geneva (2003), Prague (2004), Crete (2005), Derry (2006) and Crete (2012).
The President of CEC (from 2009 to 2013) was H.E. Metropolitan Emmanuel of France. He was succeeded in 2013 by Bishop Christopher Hill, the former Anglican Bishop of Guildford in England. The General Secretary (from June 2012) is Rev. Dr Guy Liagre, formerly President of the United Protestant Church in Belgium. He succeeded Rev. Prof. Dr Viorel Ionita who served as Interim General Secretary from 2010. The former General Secretary (2005-2010) was the Venerable Colin Williams, formerly Archdeacon of Lancaster in the Church of England; He succeeded the Rev. Dr Keith Clements.
There are a number of organisations in partnership and national councils of churches in the CEC. It is affiliated with the World Council of Churches (WCC). The CEC General Secretariat and the Churches in Dialogue Commission is located in the Ecumenical Centre, Geneva, Switzerland - which is also the headquarters building of the World Council of Churches.
Church and Society Commission
In 1999 the European Ecumenical Commission on Church and Society (EECCS) merged with CEC, becoming CEC's Church and Society Commission. The Church and Society Commission's secretariat is located in offices in Brussels, Belgium and Strasbourg, France. The Director of the Church and Society Commission from 2002 until 2013 was the Rev. Rüdiger Noll. Recent annual plenary meetings of the Church and Society Commission have been held in El Escorial, Spain (2003), Wavre, Belgium (2004), Dunblane, Scotland (2005), Sigtuna, Sweden (2006), Etchmiadzin, Armenia (2007), Prague, Czech Republic (2008) and Nyborg, Denmark (2009). Following the 14th CEC Assembly in Budapest in 2013 the programmes of the Church and Society Commission are in the process of being integrated fully into the work of CEC.
Churches in Dialogue Commission
Based in Geneva, the staff member in charge was until July 2012, Rev. Professor Father Viorel Ionita, of the Romanian Orthodox Church. The new General Secretary of CEC, Rev. Dr Guy Liagre succeeded him from 2012. From 2013 the work of the Churches in Dialogue Commission has been fully integrated in the work on ecumenical relations led by the CEC General Secretary.
Relations with the Roman Catholic Church
The largest Christian body, the Roman Catholic Church, is not a member of the CEC for the same reasons that it abstains from officially participating in the World Council of Churches, which is that such organizations do not recognize any kind of Roman Catholic primacy in the governance of the universal Church.
