The Apostolic Union of Nordland of the Ancient Bishopal Churches is one of two major subcurrents within the wider Bishopal Communion, in full communion with the Luthorian Communion. Unlike the members of the Luthorian Communion, which derive from the High Church branches of the Luthoran Abjuration and arose from colonial branches of the 21st-century Holy Luthori Church, the Union of Nordland is older, arising from a conflict of investiture of a Holy Apostolic Hosian Church Bishop in contravention of the Aurorian Hierarchy, leading to their abjuration of Archipatriarchal infallibility. This conflict was related to Juanezitism (= Jansenism), a radical predestination-based reading of the writing of the Church Fathers that the Caillean Bishop was accused of.
Today, the Union of Nordland unites a number of Bishopal Churches who first and foremost consider themselves "Ecumencial but not Patriarchal". They are under the spiritual guidance of the Metropolitan Archbishop of Nordland, who is the primus inter pares of the Communion. Their ecclesiology and theology are typified as Septenterrine, after the Selucian name of the Diocese. This gives them a High Church liturgical outlook, faithfully celebrating the Apostolic liturgy of Holy Revelation weekly, coupled with a much more progressive theological and social outlook.
