Churches as essential components of European culture have major significance for European integration. A Europe, bound by common constitutional traditions, cultures and traditions of its Member States, their national identity and the principle of subsidiarity, will have to respect the deep-rooted systems of State and Church relationships in its Member States. The volume presents in its third edition a broad comparison of different systems of State and Church relationships in the Member States of the European Union. It includes the new Member States and gives an account of the new developments throughout Europe. The volume shows the implications of European integration on the position of the Churches. It is of interest to all working in the field of State-Church relationship as well as to public and church institutions. The volume has been produced in association with the European Consortium for State-Church Research. The authors are experts in the field from the different Member States of the European Union, presenting the relevant systems of their home countries. The editor is a former professor at the University of Trier.
