Arius (/əˈraɪəs, ˈɛəri-/; Koinē Greek: Ἄρειος, Áreios; 250 or 256–336) was a Libyan presbyter and ascetic, and priest in Baucalis in Alexandria, Egypt. His teachings about the nature of the Godhead in Christianity, which emphasized God the Father’s uniqueness and Christ’s subordination under the Father, and his opposition to what would become the dominant Christology, Homoousian Christology, made him a primary topic of the First Council of Nicaea, which was convened by Emperor Constantine the Great in 325.
After Emperors Licinius and Constantine legalized and formalized the Christianity of the time in the Roman Empire, Constantine sought to unify the newly recognized Church and remove theological divisions. The Christian Church was divided over disagreements on Christology, or, the nature of the relationship between Jesus and God. Homoousian Christians, including Athanasius of Alexandria, used Arius and Arianism as epithets to describe those who disagreed with their doctrine of coequal Trinitarianism, a Homoousian Christology representing God the Father and Jesus Christ the Son as “of one essence” (“consubstantial”) and coeternal.
Negative writings describe Arius’s theology as one in which there was a time before the Son of God, when only God the Father existed. Despite concerted opposition, Arian Christian churches persisted throughout Europe, the Middle East, and North Africa, especially in various Germanic kingdoms, until suppressed by military conquest or voluntary royal conversion between the fifth and seventh centuries.
The Son’s precise relationship with the Father had been discussed for decades before Arius’s advent; Arius intensified the controversy and carried it to a Church-wide audience, where others like Eusebius of Nicomedia proved much more influential in the long run. In fact, some later Arians disavowed the name, claiming not to have been familiar with the man or his specific teachings. However, because the conflict between Arius and his foes brought the issue to the theological forefront, the doctrine he proclaimed—though not originated—is generally labeled as “his”
