The Gay Christian Movement was founded in April 1976 at a public meeting at the Sir John Cass School in the City of London, and later changed its name to the Lesbian and Gay Christian Movement, in 1987.

The Movement was based initially in the tower of St Botolph's Church, Aldgate, where the City of London meets the East End. However in 1989, after a legal challenge by the Archdeacon of London, the Church Council was compelled to evict LGCM, and Oxford House, a settlement project in Bethnal Green, took us in and provided a home for the next 25 years. In 2015 the trustees took the decision to move out of London, and relocate LGCM to a new home in Nottinghamshire.

14th February 2017 marked a very significant shift in the identity of two organisations that have campaigned for LGBTI+ liberation and integration in churches in England for over forty years. LGCM and Changing Attitude England become OneBodyOneFaith, united to campaign together for change.
