Heterousian Soterianity
Heterousian Soterianity, also known as Heterousianism, is a sect of Soterianity which arose as part of the Heterousian Controversy, a particularly divisive religious conflict which occurred early in Soterianity's history. It asserted that Soter was not coequal with God, and that the two entities were of a different nature and substance. The Controversy and its ensuing schism posed a major threat to the cohesion of the early Church, leading to its declaration as a heresy in the Council of Gazartha. As late as 1 S.C., Heterousian Soterianity remained a significant presence in northeastern Eurysia, though this would gradually wane in the ensuing centuries as the Canonical Church reasserted control.
At present, Heterousian Soterianity is regarded as an ethnoreligion, only practiced in large numbers by Bairglanders, although there is no ethnic or racial restriction placed on converts. The Bairglanders were among the last ethnic groups to be proselytized to by Heterousian Soterians before the beginning of their decline, and today almost all Bairglanders follow Heterousianism.
Theologically, Heterousianism's nontrinitarian doctrine asserts that the Son is distinct in being, or essence, from the Father and, in turn, is subordinate within the divine hierarchy. Considering this, it posits that the Son is therefore a creature made before that of the universe, and in turn claims that only the Father is independent of the notion of existence. This is in opposition to the trinitarian view seen in Gazarthan Soterianity, where the Soter (as the Son) has always existed coeternally with, and is equal alongside, the persons of the Father and Paraclete.
