The Continuing Anglican movement, also known as the Anglican Continuum, encompasses a number of Christian churches, principally based in North America, that have an Anglican identity and tradition but are not part of the Anglican Communion. These churches generally believe that traditional forms of Anglican faith and worship have been unacceptably revised or abandoned within some churches of the Anglican Communion, but that they, the Continuing Anglicans, are preserving or "continuing" both Anglican lines of apostolic succession and historic Anglican belief and practice.
