Independent sacramental movement
The Independent Sacramental Movement (ISM) is a loose collection of individuals and Christian denominations that are not part of the historic sacramental Christian denominations embodying catholicity (such as the Catholic Church, Eastern Orthodox Church, Scandinavian Lutheran Churches and Anglican churches) and yet continue to practice the historic sacramental rites independently.
The term was used in 2005 by John Plummer, in The Many Paths of the Independent Sacramental Movement, and was used earlier, in 2002, by Richard Smoley in his Inner Christianity.
