Both Unitarianism and Universalism have contributed fundamental theological concepts that remain central to Unitarian Universalism. Originally, all Unitarians were Christians who didn’t believe in the Holy Trinity of God but believed instead in the unity, or single aspect, of God. Later, Unitarian beliefs stressed the importance of rational thinking, a direct relationship with God, and the humanity of Jesus. Universalism emerged as a Christian denomination with a central belief in universal salvation, that is, that no one is born into sin, and that all persons eventually would be reconciled with God.
