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.

The Oxford Research Group (ORG) was a charity, think-tank and non-governmental organisation in the UK that was active between 1982 and 2020. The group was founded by Scilla Elworthy, an anti-war activist and author, and officially incorporated as a charity in 1988. Originally based in Oxford, the ORG relocated their base of operations to London in 2006.

The work of the ORG primarily concerned research into non-violent resolutions to conflicts around the world and opening dialogue between conflicting parties in order to find and implement peaceful solutions. The ORG approached peacebuilding from a psychological perspective, with the intention of breaking the cycles of violence that they believed caused conflict in the first place. While the ORG was a secular, non-religious group, its foundation was partly inspired by the Quaker values of peace and equality, as Elworthy herself belongs to this denomination. Though the ORG was an anti-war group, they were not pacifists.

From its foundation until 2001, the work of the ORG focused on the debate surrounding nuclear weapons and disarmament, as well as dialogue between the UK and Chinese governments on security matters and how governments could move away from the security policies of the Cold War era and towards peacebuilding based on cooperation and dialogue. After the September 11th terrorist attacks on the World Trade Center in 2001, the ORG shifted its attention to the War on Terror and peacebuilding in the Middle East in order to better understand the causes and consequences of conflict in the region, with the aim of opening dialogues between the parties involved to resolve such conflict.

In 2003, Elworthy was awarded the Niwano Peace Prize for the ORG's work. Both Elworthy and the ORG were also nominated for the Nobel Peace Prize in 1988, 1989 and 1991.

Major programmes carried out by the ORG include:

• The Sustainable Security Programme
• The Strategic Peacebuilding Programme
• The Remote Warfare Programme

Projects and groups that originated from the ORG include:

• Every Casualty Worldwide

• Peace Direct

Notable staff at the ORG included:

In 2020, the ORG could no longer operate due to funding issues.
