A celebration of the 75th anniversary of the First World Conference held in Lausanne, Switzerland, in 1927. "That meeting saw so clearly the necessity of expressing agreement in faith if churches were to come together and stay together in mission and service to God's world. The meeting identified an agenda on which agreement was deemed to be required for the unity of the church and it made advances in understanding by comparing positions held by the different churches in some of those areas". Speaking of the changes brought to the Church of England, the author notes the legacy of the `Baptism, Eucharist and Ministry' (BEM) document, which has in turn led to eucharistic hospitality, shared ministry, renewal of the diaconate and insights into apostolic succession. The theological conversation begun at Lausanne has borne fruit in many instruments of closer Christian union such as the Leuenberg Agreement, Meissen and Porvoo, to name only a few.
