Kimbanguism is a para-Christian new religious movement professed by the African initiated church Jesus Christ's Church on Earth by his special envoy Simon Kimbangu founded by Simon Kimbangu in the Belgian Congo in 1921. A large, independent African-initiated church, it has an estimated 6 million believers and has its headquarters in Nkamba, Kongo Central. The denomination became a member of the World Council of Churches, the All Africa Conference of Churches, and the Organization of African Instituted Churches. In June 2021, the World Council of Churches withdrew membership on doctrinal grounds.
