In Hosian theology, Binitarianism represents the mainstream Pneumatological view that God and Eliyahu are two distinct personalities forming a single godhead. Formalised by the Council of Auroria, the binitarian doctrine holds that God and the Spirit are coequal, pre-existing parts of the same Godhead. It is often expressed as the view that "... God is the Spirit and yet God is not the Spirit; and the Spirit is God, yet the Spirit is not God."
