I found a little bit about him online:
"John Scott, a learned divine, was born in the parish of Chippingham, in Wiltshire, in 1638, and, not being intended for a literary profession, served an apprenticeship in London, much against his will, for about three years, when he went to Oxford, where he was admitted a commoner of New Inn in 1657; but he left the university without taking a degree, and being ordained, came to London, where he officiated in the perpetual curacy of Trinity in the Minories, and as minister of St. Thomas's in Southwark. In 1677 he was presented to the rectory of St. Peter Le Poor, in Old Broad-street; and was collated to a prebend in St. Paul's cathedral in 1684. In 1685 he accumulated the degrees of bachelor and doctor in divinity. In 1691 he succeeded Sharp, afterwards archbishop of York, in the rectory of St. Giles-in-the-Fields; and in the same year he was made canon of Windsor. He died in 1694, and was buried in St. Giles's church. When Popery was encroaching under Charles II and James II, he was one of those champions who opposed it with great warmth and courage, particularly in the dedication of a sermon preached at Guildhall chapel, Nov. 5, 1683, to Sir William Hooker, lord mayor of London, in which he declares that "Domitian and Dioclesian were but puny persecutors and bunglers in cruelty, compared with the infallible cut-throats of the apostolical chair." His principal work is The Christian Life. The first part was published 1681, 8vo, with this title, "The Christian Life, from its beginning to its consummation in Glory, together with the several means and instruments of Christianity conducing there unto, with directions for private devotion and forms of prayer, fitted to the several states of Christians;" in 1685 another part, "wherein the fundamental principles of Christian duty are assigned, explained, and proved;" in 1686 another part, "wherein the doctrine of our Saviour's mediation is explained and proved." He published also Examination of Bellarmine's Eighth Note concerning Sanctity of Doctrine; The Texts Examined, which Papists cite out of the Bible concerning Prayer in an Unknown Tongue; Certain Cases of Conscience resolved, concerning the lawfulness of joining with Forms of Prayer in public worship; A Collection of Cases and other Discourses lately written to recover Dissenters to the Communion of the Church of England, 1685, 4to. All his works were published in 2 vols, fol, 1704."
An interesting note is found in Athenæ Oxonienses. Vol. 2
“John Scot of New Inn.—This learned Divine, who is not yet mentioned in these Fasti, because he took no degree in Arts, or in any other faculty, hath published divers books of Divinity (some of which were against Popery in the Reign of K. Jam. 2.) and therefore he is hereafter to crave a place among the Oxford Writers.”
