Initially a nonconforming minister, he settled at Wittersham in The Weald, an area with many Dissenters, particularly Baptists.
In 1678 he ran, with three other young nonconformist ministers (Thomas Goodwin, the younger, James Lambert and John Shower),[3] evening lectures at a coffee-house in Exchange Alley, London, which attended by merchants in the City of London.
[4] John Williams, the bishop of Chichester, encouraged Dorrington to take be ordained in the Church of England.
His publications included:[4] Dorrington translated from the Latin of Samuel Pufendorf The Divine Feudal Law, London, 1703, which is based on the late work Ius feciale divinum (1695);[12] and a new edition under the variant title A View of the Principles of the Lutheran Churches, London, 1714, which had a second edition in the same year.
[4] The subtitle of the first work goes further than Pufendorf's original, and shows that Dorrington was in 1703 angling at the Hanoverian succession, in stressing unity between Anglicans and Lutherans.
