In 1957 Spiritualist churches in Britain divided between the Spiritualists' National Union, influenced by Arthur Findlay's beliefs and holding spiritualism to be a religion, and the circles of Christian Spiritualism, who hold Spiritualism to be a denomination of Christianity. Spiritualists National Union churches form the large majority and are affiliated to Spiritualist Association of Great Britain (SAGB), which is not a church per se, but rather an organization for mediums. The SNU also has some member churches in other English-speaking countries. Christian Spiritualist churches are mainly affiliated to The Greater World Christian Spiritualist Association (GWCSA).
