Fleming was born at
Nottinghamshire on 4 November 1698. His father was a
hosier; his mother, whose maiden name was Buxton, was a daughter of the lord of the manor of
Chelmerton,
Derbyshire. Brought up in
Calvinism, Fleming's early inclination was for the independent ministry. As a boy he learned shorthand, in order to take down sermons. In 1714
John Hardy became one of the ministers of the
presbyterian congregation at the
High Pavement Chapel, Nottinghamshire, and opened a
nonconformist academy. Fleming was one of his first pupils. He was admitted as a communicant in 1715. Hardy (who conformed in 1727) taught him to discard his inheritance in
theology. He gave up the idea of the ministry and took to business, retaining, however, his theological tastes. In 1727 he left Nottingham for
London. By this time he had married and had a family. How he maintained himself is not clear. He began to publish pamphlets which attracted some attention, but remained poor. In 1727 a
Catholic tried to make a convert of him, but desisted on discovering that he had to deal with an
anti-trinitarian. Some help in further classical and biblical study was given to him by
John Holt, then a presbyterian minister in London, later mathematical tutor at
Warrington Academy, and he learned
Hebrew from a
rabbi. Through
William Harris, D.D., presbyterian minister at Crutched Friars, an offer was made for his services as a government pamphleteer. He replied that he "would sooner cut off his right hand." In 1736 he published a pamphlet,
The Fourth Commandment abrogated by the Gospel, dedicating it to his namesake,
Sir George Fleming, bishop of Carlisle. It would appear that he had been advised to do this by
John Thomas, afterwards bishop of Winchester. Bishop Fleming offered him the living of
Lazonby,
Cumberland, worth some £600 a year. Dr. Thomas was ready to advance what was needed for his move, but Fleming could not conform. In his refusal, he was supported by his wife. His friends now began to urge him to enter the dissenting ministry. In his fortieth year he preached his first sermon to the presbyterian congregation at
Wokingham,
Berkshire, Catcot, the minister, publicly thanking him for his services. After this he officiated at a few places in the neighbourhood of London. At length, on the death of John Munckley (August 1738), he was strongly recommended by
Benjamin Avery as a suitable candidate for the charge of the presbyterian congregation at Bartholomew Close. There, Fleming and William May were ordained as joint pastors in 1740. Fleming had scruples about presbyterian forms, and classed himself as an independent. At his ordination, conducted by
Samuel Chandler,
Jeremiah Hunt, and others, he refused to submit to the
imposition of hands, His confession of faith was unique. He would only say that he believed the New Testament contained "a revelation worthy of God to give and of man to receive;" and this he promised to teach in the sense in which he should "from time to time" understand it. It was soon rumoured that Fleming was a
Socinian. His congregation was never large, and the scantiness of his stipend reduced him to dire financial straits. His friends fell off, with the exception of Jeremiah Hunt. After Hunt's death (1744) Fleming was on good terms with
Nathaniel Lardner, D.D., his neighbour in
Hoxton Square, and co-operated with him in literary work. In January 1752
James Foster, became disabled from preaching. John Weatherley (d. May 1752), a
General Baptist minister, who supplied Foster's place, met Fleming at Hamlin's Coffee-house, and engaged him for a Sunday at Pinners' Hall, an Independent congregation. He attracted the notice of Timothy Hollis, was soon afterwards elected as Foster's assistant, and on Foster's death (5 November 1753) as pastor. The Bartholomew Close congregation then came to an end, its few remaining members joining Pinners' Hall. For nearly a quarter of a century Fleming remained at his post; his ministry, though painstaking, was not popular, and when he ceased to preach, in December 1777, his congregation became extinct, the lease of their meeting-house expiring in 1778. He had admirers, who left him considerable legacies, among them being a bequest by a Suffolk gentleman (Reynolds), who had once heard him preach but did not know his name. A wealthy widow placed her whole fortune at his disposal. Fleming, however, declined to be enriched at the expense of her needy relatives. In his old age his friend
William Dalrymple of Ayr procured for him the degree of D.D. from St. Andrews. Fleming was inclined to reject this "compliment"; but his friend
Thomas Hollis "put it into the public papers",’ so Fleming accepted it in a letter (6 April 1769). After completing his seventy-ninth year, Fleming retired. He died on 21 July 1779, and was buried in
Bunhill Fields. He left an epitaph for his gravestone, in which he describes himself as "dissenting teacher", and expresses a conditional hope of immortality. For this, however, was substituted a eulogistic inscription by
Joseph Towers, LL.D. His funeral sermon was preached by
John Palmer at New Broad Street. A portrait of Fleming, by William Chamberlain, was bequeathed by him to
Dr. Williams's Library. ==Works==
