The Chicago-Lambeth Quadrilateral is a declaration adopted by the House of Bishops in Chicago in 1886. It outlines the essential principles for Christian unity, emphasizing the Holy Scriptures, the Nicene Creed, the two sacraments, and the Historic Episcopate. The document expresses a desire for unity among Christian denominations based on these foundational elements.
The Anglican Communion Office (ACO) is the official secretariat of the Anglican Communion – a worldwide network of Anglican churches, in over 165 countries. The ACO connects member churches, encourages global mission, fosters Christian unity, promotes ecumenism and amplifies Anglican advocacy.
The ACO also supports and facilitates the ‘Instruments of Communion’: The Anglican Consultative Council, The Lambeth Conference, the Primates’ Meeting and the Archbishop of Canterbury.
