John Jackson (controversialist)
John Jackson (1686–1763) was an English clergyman and controversial theological writer.

Life
Jackson was born at Sessay, near Thirsk in the North Riding of Yorkshire on 4 April 1686, eldest son of John Jackson (died 1707, aged about 48), rector of that parish. His mother's maiden name was Ann Revell. 

He attended Doncaster grammar school, after which he entered Jesus College, Cambridge in 1702, and went into residence at midsummer 1703. 
He studied Hebrew under Simon Ockley. Graduating B.A. in 1707, he became tutor in the family of Simpson, at Renishaw, Derbyshire. His father had died rector of Rossington, West Riding of Yorkshire, and this preferment was conferred on Jackson by the corporation of Doncaster on his ordination as a deacon in 1708, and as a priest in 1710.

In 1718, Jackson went to Cambridge for his M.A.; the degree was refused on the ground of his writings respecting the Trinity. The following year he was presented by Nicholas Lechmere, chancellor of the duchy of Lancaster, to the confratership of Wigston's Hospital, Leicester. Samuel Clarke held the mastership of the hospital, and recommended Jackson. The post did not involve subscription to the Thirty-nine Articles, and carried with it the afternoon lectureship at St. Martin's, Leicester, for which Jackson, who removed from Rossington to Leicester, received a licence on 30 May 1720 from Edmund Gibson, as bishop of Lincoln. On 22 February 1722, he was inducted to the private prebend of Wherwell, Hampshire, on the presentation of Sir John Fryer; here also no subscription was required. The mastership of Wigston's Hospital was given to him on Clarke's death (1729) by John Manners, 3rd Duke of Rutland, chancellor of the Duchy of Lancaster. Several presentments had previously been lodged against him for heretical preaching at St. Martin's, and when he wished to continue the lectureship after being appointed master, the vicar of St. Martin's succeeded (1730) in keeping him out of the pulpit by somewhat forcible means.

In 1730, Benjamin Hoadly offered him a prebend at Salisbury Cathedral on condition of subscription, but after the 1721 publication of Daniel Waterland's Case of Arian Subscription he had decided to subscribe no more. In September 1735, he went to Bath, Somerset for the benefit of a dislocated leg. On 28 September, he preached at St. James's, Bath, at the curate's request. Dr. Coney, the incumbent, preached on 12 October, and refused the sacrament to Jackson, on the plea that he did not believe the divinity of Christ. Jackson complained to the bishop John Wynne, who disapproved of Coney's action.

Jackson married Elizabeth, daughter of John Cowley, a collector of excise at Doncaster, in 1712, and they had twelve children. She died in 1760. He died at Leicester on 12 May 1763. His son John and three daughters (all married) survived him.

Works
Jackson was prompted to take on controversial topics by the publication (1712) of the Scripture Doctrine of the Trinity by Samuel Clarke. His first publication was a series of three letters, dated 14 July 1714, by 'A Clergyman of the Church of England,' in defence of Clarke's position. He corresponded with Clarke, and made his personal acquaintance at King's Lynn. Jackson's theological writings were anonymous; he acted as a mouthpiece for Clarke, who kept in the background after promising Convocation, in July 1714, to write no more on the subject of the Trinity. William Whiston, in a letter to William Paul, 30 March 1724, says that

Dr. Clarke has long desisted from putting his name to anything against the church, but privately assists Mr. Jackson; yet does he hinder his speaking his mind so freely, as he would otherwise be disposed to do.

Almost simultaneously with his first defence of Clarke, Jackson advocated Benjamin Hoadly's views on church government in his Grounds of Civil and Ecclesiastical Government, 1714; 2nd edit. 1718. In 1716, he corresponded with Clarke and Whiston on the subject of baptism, defending infant baptism against Whiston; his Memoirs contained a previously unpublished reply to the anti-baptismal argument of Thomas Emlyn.

Jackson was a prolific writer of treatises and pamphlets, many of them against the deists. Jackson's later years were spent in the compilation of his Chronological Antiquities (1752). He published also:
