Stephen Charles Neill (1900–1984) was a Scottish Anglican missionary, bishop, and scholar. He was proficient in a number of languages, including Greek, Latin and Tamil. He went to Trinity College, Cambridge and was a fellow there before going as a missionary to Tamil Nadu, in British India, and became bishop of Tirunelveli in 1939.
He believed in unification of all churches in South India and communion beyond denominations. He wrote several books on theology and church history.
Neill was born in Edinburgh, Scotland on 31 December 1900 to Charles Neill and Margaret Penelope ("Daisy") Neill, the daughter of James Munro (for a time Commissioner (CID) at Scotland Yard who, having resigned at the age of 52 on disagreeing with the government, returned to India, where he had been a district officer, to establish a medical misison). Both his parents were missionary doctors in India but spent much of their adult lives in various European countries for reasons of health and for the sake of their children's education. He had two sisters, Marjorie Penelope (1898) and Isabel Ruth (1906), and three brothers: Christopher Henry (1899), Gerald Munro (1902), Eric James (1904).
He was educated at Dean Close School, then in 1918 won a scholarship to Trinity College, Cambridge and was elected to a fellowship in 1924. While still in Cambridge he passed the Church of England's General Ordination Examination which qualified him for ordination but he had decided to go out to India as a layman.
In 1925 he moved to Dohnavur with his parents. While at Dohnavur he learnt Tamil and was involved in teaching schoolboys. Neill joined the Church Missionary Society (CMS) in 1928 and was ordained a priest. After his ordination he moved to Tirunelvely and later led Thomas Ragland's North Tirunelveli Itineracy evangelism program. He taught Tamil in the CMS theological college in Palayamkottai where he served as its first Principal. There he became involved in negotiations for uniting the churches in South India for the formation of Church of South India. He believed that all churches should unite and no church should be left out as not being in communion. He was elected the bishop at Tirunelveli in 1939. There he held the diocese together during the troubled times of the war, resisting encroachments by the state and initiating development projects in publishing, banking among other areas. In 1944 he resigned. In his autobiography, he attributes this to problems of ill health which had dogged him for most of his life. The editor of the biography notes that in the Diocese the common view is that he had to leave because of instances when he had struck his clergy and he adds that more serious allegations were made.
