The organisation of the Methodist Church of Great Britain is based on the principle of connexionalism. This means that British Methodism, from its inception under John Wesley (1703–1791), has always laid strong emphasis on mutual support, in terms of ministry, mission and finance, of one local congregation for another. No singular church community has ever been seen in isolation either from its immediately neighbouring church communities or from the centralised national organisation. Wesley himself journeyed around the country, preaching and establishing local worshipping communities, called "societies", often under lay leadership. Soon these local communities of worshipping Christians formalised their relationships with neighbouring Methodist communities to create "circuits", and the circuits and societies contained within them, were from the very beginning 'connected' (hence the distinctive Methodist concept of the "Connexion") to the centre and Methodism's governing body, the annual Conference. Today, societies are better known as local churches, although the concept of a community of worshipping Christians tied to a particular location, and subdivided into smaller cell groups called "classes", remains essentially based on Wesley's societies. Other Methodist Churches which were established by British Missionaries are also modelled on the structure of the British Church. Historical origins The first circuits, 1746 The earliest preachers under John Wesley were itinerant, and preached around an area from a home base. The "circuit", or "round" as they were first named, was therefore the natural name for the area they covered. At first they were named after their founder of main itinerant preacher. For example, 'John Bennet's Round', or the 'Circuit of William Darney's Societies'. The first official list dates from 1746. London (including Surrey, Kent, Essex, Brentford, Egham, Windsor, Wycombe); Bristol (including Somerset, Portland, Wiltshire, Oxfordshire, Gloucester); Cornwall Evesham (including Shrewsbury, Leominster, Hereford, and from Stroud to Wednesbury); Yorkshire (including Cheshire, Lancashire, Derbyshire, Nottinghamshire, Rutland, Lincolnshire); Newcastle Wales Within that area a number of "societies" would be formed. During the 18th century, John Wesley did not intend establishing churches in a new denomination. His vision was for a revival movement within the Church of England. The societies would be a gathering of people who met for Bible study, prayer, mutual encouragement, and preaching. Usually, this was during the week so that they could attend services in the parish church. The earliest circuits covered a very large area, but gradually shrank as the number of societies increased.
