Chapels and organisations
As his societies needed houses to worship in, Wesley began to provide chapels, first in Bristol at the New Room, then in London (first The Foundery and then Wesley's Chapel) and elsewhere. The Foundery was an early chapel used by Wesley. The location of the Foundery is shown on an 18th-century map, where it rests between Tabernacle Street and Worship Street in the Moorfields area of London. When the Wesleys spotted the building atop Windmill Hill, north of Finsbury Fields, the structure which previously cast brass guns and mortars for the Royal Ordnance had been sitting vacant for 23 years; it had been abandoned because of an explosion on 10 May 1716.
The Bristol chapel (built in 1739) was at first in the hands of trustees. A large debt was contracted, and Wesley's friends urged him to keep it under his own control, so the deed was cancelled and he became sole trustee. Following this precedent, all Methodist chapels were committed in trust to him until by a "deed of declaration", all his interests in them were transferred to a body of preachers called the "Legal Hundred".
When disorder arose among some members of the societies, Wesley adopted giving tickets to members, with their names written by his own hand. These were renewed every three months. Those deemed unworthy did not receive new tickets and dropped out of the society without disturbance. The tickets were regarded as commendatory letters.
When the debt on a chapel became a burden, it was proposed that one in 12 members should collect offerings regularly from the 11 allotted to him. Out of this grew the Methodist class-meeting system in 1742. To keep the disorderly out of the societies, Wesley established a probationary system. He undertook to visit each society regularly in what became the quarterly visitation, or conference. As the number of societies increased, Wesley could not keep personal contact, so in 1743 he drew up a set of "General Rules" for the "United Societies". These were the nucleus of the Methodist Discipline, still the basis of modern Methodism.
Wesley laid the foundations of what now constitutes the organisation of the Methodist Church. Over time, a shifting pattern of societies, circuits, quarterly meetings, annual conferences, classes, bands, and select societies took shape. At the local level, there were numerous societies of different sizes which were grouped into circuits to which travelling preachers were appointed for two-year periods. Circuit officials met quarterly under a senior travelling preacher or "assistant." Conferences with Wesley, travelling preachers and others were convened annually for the purpose of co-ordinating doctrine and discipline for the entire connection. Classes of a dozen or so society members under a leader met weekly for spiritual fellowship and guidance. In the early years, there were "bands" of the spiritually gifted who consciously pursued perfection. Those who were regarded to have achieved it were grouped in select societies or bands. In 1744, there were 77 such members. There also was a category of penitents which consisted of backsliders.
As the number of preachers and preaching-houses increased, doctrinal and administrative matters needed to be discussed; so John and Charles Wesley, along with four other clergy and four lay preachers, met for consultation in London in 1744. This was the first Methodist conference; subsequently, the Conference (with Wesley as its president) became the ruling body of the Methodist movement. Two years later, to help preachers work more systematically and societies receive services more regularly, Wesley appointed "helpers" to definitive circuits. Each circuit included at least 30 appointments a month. Believing that the preacher's efficiency was promoted by his being changed from one circuit to another every year or two, Wesley established the "itinerancy" and insisted that his preachers submit to its rules.
John Wesley had strong links with the North West of England, visiting Manchester on at least fifteen occasions between 1733 and 1790. In 1733 and 1738 he preached at St Ann's Church and Salford Chapel, meeting with his friend John Clayton. In 1781 Wesley opened the chapel on Oldham Street—part of the Manchester and Salford Wesleyan Methodist Mission, now the site of Manchester's Methodist Central Hall.
Wesley travelled to Ireland for the first time in 1747 and continued through 1789. He rejected the Catholic Church, so he worked to convert the people of Ireland to Methodism. Overall, the numbers grew to over 15,000 by 1795.
Following an illness in 1748 Wesley was nursed by a class leader and housekeeper, Grace Murray, at an orphan house in Newcastle. Taken with Grace, he invited her to travel with him to Ireland in 1749 where he believed them to be betrothed though they were never married. It has been suggested that his brother Charles Wesley objected to the engagement, though this is disputed. Subsequently, Grace married John Bennett, a preacher.
