The Governing Body of Jehovah's Witnesses is the ruling council of Jehovah's Witnesses, based in the denomination's Warwick, New York, headquarters. The body formulates doctrines, oversees the production of written material for publications and conventions, and administers the denomination's worldwide operations. Official publications refer to members of the Governing Body as followers of Christ rather than religious leaders. Its size has varied, from seven (2010–2012, 2014–2018) to eighteen (1974–1975, 1977–1979) members. New members of the Governing Body are selected by existing members.
