In 1695 he was chosen assistant to Thomas Gouge, pastor of the independent church at Three Cranes, Fruiterers' Alley, Thames Street, London.
His position as a teacher was that of a bulwark of dissenting orthodoxy against the prevalent tendencies to Arian and Arminian laxity.
Yet his scheme of the Trinity, denuded of the generation of the Son and the procession of the Spirit, is essentially Sabellian, and in easing the difficulties of Calvinism he follows the Socinians in limiting the penalties of Adam's sin to death and temporal discomfort.
In 1719 he took the side of subscription in the Salters' Hall debates, thus ranging himself with the older presbyterians; while Hunt, Lowman, Lardner, and Jennings, his juniors among the learned independents, were for non-subscription.
He published, besides single sermons, including funeral sermons for Gertrude Clarkson (1701), Elizabeth Bankes (1711), Nathan Hall (1719), Thomas Tingey (1729), John Hurrion (1732), and John Sladen (1733, two editions same year): Media related to Thomas Ridgley at Wikimedia Commons
