 Charles Daubeny (1745-1827) formulated a branch theory in which the One, Holy, Catholic, and Apostolic Church included the Anglican, Scandinavian Lutheran, Roman Catholic and Eastern Orthodox Churches; to this the Oriental Orthodox Churches, Moravian Church, Church of the East, and Old Catholic Churches were also added.The theory was popularized during the Oxford Movement, particularly through the work of the Tractarians.Although the Anglican Roman Catholic International Commission, an organization sponsored by the Anglican Consultative Council and the Pontifical Council for Promoting Christian Unity, seeks to make ecumenical progress between the Roman Catholic Church and the Anglican Communion, it has made no statement on the topic.
