At first the organisation represented a loose association of churches, but with the adoption of a Constitution at the 1964 Assembly a significant step was taken towards forming a regional conference of churches. This Assembly was held at sea, aboard the m.v. Bornholm, in order to overcome last-minute visa difficulties.
The fifth Assembly in 1967, held in Pörtschach, Austria, created a full time secretariat as from April 1968. Subsequent Assemblies were held in Nyborg Strand (1971), Engelberg, Switzerland (1974), Chania, Crete (1979), Stirling, Scotland (1986), Prague, former CSFR (1992) when a radically revised Constitution was adopted, Graz, Austria (1997) and Trondheim, Norway (2003).
