Born at
Maidstone in
Kent on 15 May 1794, he was son of Abraham Harris, Unitarian minister at
Swansea for 40 years. George was at the age of fourteen placed in a Manchester warehouse in
Cheapside, London, but, wishing to enter the Unitarian ministry, he gave up his place. In his eighteenth year he entered the
Islington Academy, then under
John Evans. In November 1812 he matriculated at
Glasgow University, on a bursary from Dr
Daniel Williams's trust, and attended classes in
Glasgow during three winter sessions. His studies were interrupted by engagements as a preacher and lecturer. The
Scottish Unitarian Associationwas formed in July 1813. Harris was one of its originators, and was for three years its secretary. He also spent time in establishing Unitarian churches, principally in
Paisley,
Greenock, and neighbouring towns, and in directing Unitarian stations in different parts of Scotland. In 1816 he issued
A Statement of the Principles of Unitarian Christianity addressed to the Inhabitants of Greenock and Port Glasgow, and to the Friends of Free Inquiry throughout Scotland, by a Unitarian[https://books.google.com/books?id=ZPoTAAAAYAAJ, a concise manual of Unitarian teaching. By his efforts a Unitarian chapel was erected in
Port Glasgow. It was opened by him in January 1822; the sermon which he preached on the occasion was published. At this period he also published
Select Pieces for Reading and Recitation. In April 1817, Harris was invited to become minister of
Renshaw Street Unitarian Chapel in
Liverpool, then vacant by the resignation of Robert Lewin. He was inducted in July, and his convictions soon engaged him in numerous controversies. Many censured his severe attacks on evangelical doctrine. His pamphlet,
Unitarianism, the only Religion which can become Universal, and a course of Sunday evening lectures, published as
Unitarianism and Trinitarianism contrasted, called forth replies. Dr. James Barr of Oldham Street Presbyterian Church, Dr. John Stewart of Mount Pleasant Secession Church, and Mr. Jones of St. Andrew's Church were his most prominent opponents. In 1818 Harris planned a
Unitarian Christian Association for the dissemination of
unitarian literature, and he travelled through Lancashire and Cheshire to gain for it sympathy and support. In the summer of 1821 a division occurred in the
Bank Street Unitarian congregation,
Bolton, and in 1822 Harris accepted an invitation to become minister of the seceders. They first met at the
Cloth Hall, but in 1823 the Moor Lane Church was purchased from the
Scottish presbyterians. Harris was known in Manchester as ‘the intrepid champion of
Socinianism.’ In 1822 he published
The Lancashire and Cheshire Unitarian Association, and the Christian Reflector vindicated; in 1823 he published an account of the formation of the Moor Lane congregation, some statements in which provoked replies from other clergymen; and in 1824 appeared
Christianity defended. In 1824 a speech by him in Manchester led to a long correspondence, which was afterwards published under the title of
The Manchester Socinian Controversy, and indirectly caused the
Hewley lawsuit. In September 1825 Harris resigned his charge in Bolton, and moved to Glasgow, his wife's native place. He preferred the call to
Glasgow to one from London, ‘because,’ he said, 'he wished to stand in the front of the battle.' The evangelical revival led by
Thomas Chalmers was then at its height, but Harris attracted large audiences. In 1841 Harris moved to
Edinburgh to assist in reviving the Unitarian congregation. He stayed four years, though with less success than in Glasgow, and in 1845 he accepted an invitation to become the minister of Hanover Square Chapel,
Newcastle-upon-Tyne. A new church was erected in 1854, and a large congregation gathered. He died on 24 December 1859. ==Works and views==
