Question: George Whitefield, Charles Wesley and John Wesley started the Methodist movement in the 18th century within which church denomination?
Context: Whitefield's Tabernacle on Tottenham Court Road, a church in London, England, also called Tottenham Court Road Chapel, was built in 1756 for George Whitefield.  It was enlarged in 1759.  John Wesley preached a sermon "On the death of the Rev Mr George Whitefield" both here and at Whitefield's Tabernacle, Moorfields, in 1770. Wesley is a 2009 biopic about John Wesley and Charles Wesley, the founders of the Methodist movement.  The movie is based largely on the Wesley brothers' own journals, including John's private journal which was kept in a shorthand-like code that was not translated until the 1980s by Dr. Richard Heitzenrater at Duke Divinity School. The Methodists formed a new church in the early 18th century as a break away movement from the established Church (Church of England), mainly by two Anglican ministers, John Wesley, the preacher and his brother, Charles Wesley, the hymn writer.  The Methodist Church has had a following in Ripley from the formation of the earliest church up to the present day. Whitefield's Tabernacle, Moorfields (also known as Moorfields Tabernacle) is a former church at the corner of Tabernacle Street and Leonard Street, Moorfields, London, England.  The first church on the site was a wooden building erected by followers of the evangelical preacher George Whitefield in 1741.  This was replaced by a brick building in 1753.  John Wesley preached a sermon "On the death of the Rev Mr George Whitefield" both here and at Whitefield's Tabernacle, Tottenham Court Road in 1770. Charles Wesley's House (grid reference [ ST589736] ) is a restored historic building at 4 Charles Street, Bristol, England.  From 1749 to 1778 it was the house of Charles Wesley, hymn writer and co-founder of Methodism, and his wife Sarah Wesley née Gwynne.  It was Charles Wesley's main residence during 1756–71.  It was the childhood home of his sons Charles Wesley junior and Samuel Wesley.  They were musical child prodigies, who both became renowned organists and composers.  The house's interior has been restored to its 18th century appearance, with period fittings. Methodism or the Methodist movement is a group of historically related denominations of Protestant Christianity which derive their inspiration from the life and teachings of John Wesley.  George Whitefield and John's brother Charles Wesley were also significant leaders in the movement.  It originated as a revival within the 18th century Church of England and became a separate denomination after Wesley's death.  The movement spread throughout the British Empire, the United States, and beyond because of vigorous missionary work, today claiming approximately 80 million adherents worldwide. The Wesleyan Methodist Church was the name used by the majority Methodist movement in Great Britain following its split from the Church of England after the death of John Wesley and the appearance of parallel Methodist movements.  The word "Wesleyan" was added to the title to differentiate it from the Welsh Calvinistic Methodists, founded by George Whitefield who, like Wesley and his brother Charles, had been a member of the Holy Club in Oxford to which the (originally derogatory) epithet "Methodist" was first applied, and from the Primitive Methodist movement, which separated from the Wesleyans in 1807.  The Wesleyan Methodist Church followed the Wesleys in holding to an Arminian theology, as against Whitefield's Calvinism; its Conference was also the legal successor to John Wesley as holder of the property of the original Methodist Societies. John Wesley ( or ; 28 June [O.S. 17 June] 1703 2 March 1791) was an English Anglican cleric and theologian who, with his brother Charles and fellow cleric George Whitefield, founded Methodism. Selina, Countess of Huntingdon (24 August 1707 – 17 June 1791) was an English religious leader who played a prominent part in the religious revival of the 18th century and the Methodist movement in England and Wales, and has left a Christian denomination (Countess of Huntingdon's Connexion) in England and in Sierra Leone in Africa.  She played a major role in financing and guiding early Methodism.  Selina was the first female principal of a men's college in Wales (Trefeca College, for the education of Methodist ministers).  She financed the building of 64 chapels in England and Wales, wrote often to George Whitfield and John Wesley, and funded mission work in colonial America.  She is best remembered for her adversarial relationships with other Methodists who objected to a woman having power. Wesley's Chapel is a Methodist church in London that was built under the direction of John Wesley, the founder of the Methodist movement.  It is now a place of worship and visitor attraction, incorporating the Museum of Methodism in its crypt and John Wesley's House next to the chapel.
