The Ecclesia Gnostica (Latin for The Church of Gnosis or The Gnostic Church) is an openly Gnostic liturgical church that practices and offers its sacraments publicly. It is centered in Los Angeles, California with parishes in Seattle, Washington; Portland, Oregon; Salt Lake City, Utah; Sedona, Arizona; and Oslo, Norway. The church and its affiliate, the Gnostic Society, attempt to "make available the philosophy and practice of gnosticism to the contemporary world."
The organization now called the Ecclesia Gnostica was originally organized in England under the name the Pre-Nicene Gnostic Catholic Church in 1953, by the Most Rev. Richard Jean Chretien Duc de Palatine with the object of “restoring the Gnosis - Divine Wisdom to the Christian Church, and to teach the Path of Holiness which leads to God and the Inner Illumination and Interior Communion with the Soul through the mortal body of man.” Born Ronald Powell, Richard Duc de Palatine had served in the Liberal Catholic Church in Australia, before moving to England. Bishop Duc de Palatine was consecrated by the Most Rev. Msg. Hugh George de Willmott Newman (Mar Georgius I), patriarch of the Catholic Apostolic Church (Catholicate of the West) who consolidated many lines of apostolic succession.
Bishop Duc de Palatine also received a charter in 1953 to head an organization first called "the Brotherhood of the Illuminati," renamed "the Order of the Pleroma" in 1960. He received other esoteric lines and charters such as: the Templar Order, Brotherhood of the Rosy Cross, Memphis and Mizarim Rites of Freemasonry, and the Martiniste Order, and termed the combination with the Ecumenical Apostolic Succession "the Wisdom Religion-Gnostic Mystic Tradition."
