Thomas Morgan was born in Wales and died on 14 January 1743. He was at one time a dissenting minister at Frome, Somerset, from which position he was dismissed for holding deistic opinions. He began to publish in the wake of the ‘Salters’ Hall' controversy in 1719, arguing that dissenting ministers ought not to have to subscribe to orthodox formulations on the doctrine of the Trinity in order to exercise their ministries. On his dismissal, he became a physician and controversialist. His case demonstrates the inexactitude of the term ‘deist’ rather well, since, as J.M. Robertson noted, ‘Towards the Jehovah and the ethic of the Old Testament he holds, however, the attitude rather of an ancient Gnostic than of a modern rationalist; and in his philosophy he is either a very “godly” deist or a pan-theist miscarried.’ Morgan's term for this identification was the somewhat confusing one of ‘Christian Deism’.
