''A spiritualist church is a church affiliated with the informal spiritualist movement which began in the United States in the 1840s. Spiritualist churches are now found around the world, but are most common in English-speaking countries, while in Latin America, where a form of spiritualism called spiritism is more popular, meetings are held in spiritist centres, most of which are non-profit organizations rather than ecclesiastical bodies.''
