The Church of Neo-Britain is by far the largest organized faith on Neo-Britain. It was originally a purely Christian sect, based upon the Anglicanism of the Church of England on Earth in the Old Universe. When Neo-Britain came under the control of the New Shi'ar Imperium, the Church of Neo-Britain, converted to a syncretic mix of Christianity and Shi'ar beliefs, particularly those of the Church of the True God, including belief in the True God (identified with God the Father of Christianity) and reincarnation of souls into new bodies.
Jesus Christ became an avatar of the True God to guiding souls in their path of reincarnation. The Christian Bible was reduced to secondary importance, subordinate to Shi'ar religious texts.
Leadership of the Church of Neo-Britain is vested in the Archbishop of Neo-Britain, and a hierarchy of bishops, priests, and deacons.
