Arius (256-336 A.D.) is the most famous heretic of Christian theology. He was born in Libya and died in Constantinople. Arius held a prominent position as a priest in the Church of Alexandria when he started a theological controversy in 318. Arius denied the eternal deity of Christ and his equality with the Father. He argued that Christ was created by the Father.
Since the age of the Apostles, Jesus had always been considered divine by his followers, but his precise relation to the Godhead had not yet been defined. Thanks to Arius, the Trinitarian controversy regarding the status of Jesus Christ erupted.
Arius’ View of Jesus
Arius did not believe that the Father and the Son were of the same substance. Instead, he believed in the eternal functional and ontological subordination of the Son to the Father—that the Son was a lower being than the Father.
According to Arius, the Son was created before time. In other words, he was not co-eternal with the Father. As he put it, “Before he was begotten or created or appointed or established, he did not exist; for he was not unbegotten” (Letter to Eusebius). Furthermore, the Son was not of one divine substance with the Father. He was rather of a similar substance with the Father (homoiousios). On this view, the divine qualities of the Son are given to him by the Father.
Arius claimed that when the Scriptures speak of Jesus as the “Son” of God, it is merely a title of honor—a title given to Jesus as the one on whom the Father had lavished a special grace. Thus, Arius says, “He is not God truly, but by participation in grace…He too is called God in name only” (Early Christian Doctrines).
The theology of Arius became so controversial that Constantine intervened in 325, calling the Council of Nicaea. Athanasius, the leading defender of Nicene orthodoxy and the most prolific writer of orthodox Trinitarian doctrine in the fourth century, saw a major flaw in the writings of Arius and called his heresy the “forerunner of the Antichrist” (Athanasius, Or. Ar. 1:1).
According to Athanasius, the Son was eternally begotten from the Father such that he can be said to be of the same essence (homoousios) with the Father: “The Son is other in kind and nature than the creatures, or rather belongs to the Father’s substance and is of the same nature as He.” (Athanasius, Contra Arianos, III).
Why Does All This Matter?
There are some today who repeat Arius’ views. However, Jesus claimed to be God and the Christian tradition has held that there is an intimate connection between salvation and the deity of Christ.
We are saved from God by God. Only a divine Savior can bear the weight of God’s wrath in atonement. Only Jesus as the God-man can satisfy the enormous debt and penalty caused by human sin against God. No mere human could bridge that gap. Only a divine Savior can pay the costly price of redeeming us from our bondage to sin and death. Only the God-man can conquer all his people’s enemies. Our salvation rests on the infinite capacities of our savior, Jesus Christ.
