The Church of England has produced a set of Liturgical Resources for use at services commemorating the anniversary of World War One. They are available here as part of a section of the website dedicated to the commemoration.
A candle-lit vigil of prayer and an act of solemn reflection to mark the centenary of the start of the First World War will be held in Westminster Abbey on 4 August 2014. The service is one of a number of events being announced by the Government to mark the centenary of the Great War. Drawing upon Sir Edward Grey’s famous remark that “the lights are going out all over Europe”, the Abbey will mark the centenary by moving from light into darkness, until one candle remains at the Grave of the Unknown Soldier, which will be extinguished at 11.00pm to mark the moment at which Britain entered the war.
