What did Arius believe about God?

In the early fourth century, Alexandria was a bustling hub of intellectual and theological activity. Christian leaders grappled with how to express the relationship between God the Father and Jesus Christ as Christians sought to define their faith more precisely, especially in the face of various heresies and philosophical challenges. The core question was: If Christians affirm “one God,” how do they understand the divinity of Jesus and the nature of the Trinity?

Arius, a respected presbyter in Alexandria, entered this debate with teachings that would challenge the prevailing understanding of Christ’s divinity and God’s uniqueness. His ideas sparked intense controversy, leading to rifts within the church and ultimately to an official condemnation at the Council of Nicaea.

Arius’s Core Beliefs about God

1. The Absolute Uniqueness and Transcendence of God the Father

At the heart of Arius’s theology was the conviction that God the Father is utterly unique, eternal, and transcendent. Arius insisted that only the Father is truly unbegotten and without origin. For Arius, this absolute transcendence meant that God could not share His essence or nature with any other being—not even the Son. To Arius, to claim that the Son was eternally begotten from the Father’s own substance would compromise the Father’s uniqueness and transcendence.

2. The Created Nature of the Son

Arius’s most controversial teaching was that the Son (the Logos, or Word, identified with Jesus Christ) was not co-eternal with the Father but was a created being. Arius famously summarized his position with the phrase: “There was when he was not.” In other words, the Son did not exist from eternity, but came into being by the will of the Father before the creation of the world.

Arius taught that the Son was the first and greatest of God’s creations—through whom all other things were made—but was nevertheless distinct from, and subordinate to, the Father. The Son was divine in a secondary sense, but not of the same essence (Greek: homoousios) as the Father. Instead, he was of “similar essence” (homoiousios) or even of a different essence (heteroousios), depending on the interpretation of Arius’s followers.

3. The Son as Mediator and Exemplar

Arius did not deny the Son’s exalted status. He affirmed that the Son was the agent of creation and the one through whom God revealed Himself to humanity. The Son’s unique role as mediator and teacher was central to Arius’s theology. However, for Arius, the Son’s greatness did not mean equality with the Father. Instead, the Son was a perfect creature, the highest of all, but not God in the fullest sense.

4. The Subordination of the Son and the Spirit

In Arius’s view, the Son was subordinate to the Father, not only in role but in nature and being. The Holy Spirit, likewise, was seen as subordinate to both the Father and the Son. This hierarchy preserved, in Arius’s mind, the oneness and supremacy of God the Father.

Arius’s Scriptural Arguments

Arius believed his position was grounded in Scripture. He pointed to passages that seemed to distinguish the Son from the Father and suggest the Son’s derived or subordinate status. Key verses included:

• John 14:28: “The Father is greater than I.”
• Colossians 1:15: “[The Son] is the image of the invisible God, the firstborn of all creation.”
• Proverbs 8:22: “The Lord created me at the beginning of his work,” interpreted by Arius as referring to the pre-existent Christ.
• Mark 13:32: “But about that day or hour no one knows, neither the angels in heaven, nor the Son, but only the Father.”

Arius used such texts to argue that the Son, while exalted, was not equal to the Father in essence or eternity.

Philosophical Influences

Arius’s theology was also shaped by the philosophical climate of his time. Greek philosophical traditions, particularly Neoplatonism, emphasized the absolute oneness and simplicity of the divine. To Arius, the idea of God sharing His very substance with another being seemed to threaten this oneness. By making a clear distinction between the uncaused Father and the caused Son, Arius sought to preserve God’s transcendence and uniqueness.

Theological Implications and Controversy

Arius’s teachings raised profound questions about salvation, worship, and the identity of Jesus. If the Son is not fully God, can he truly reveal God to humanity or effect salvation? Should Christians worship the Son if he is a creature? These questions led to strong opposition from other church leaders, most notably Athanasius of Alexandria, who argued that only if the Son is truly God can he save.

The controversy soon extended beyond theology into politics and church unity. The spread of Arian beliefs threatened to divide the Christian community, prompting Emperor Constantine to call the Council of Nicaea in 325.

The Council of Nicaea and the Condemnation of Arianism

At Nicaea, bishops from across the Christian world debated Arius’s teachings. The council ultimately rejected Arianism, affirming that the Son is “begotten, not made, being of one substance (homoousios) with the Father.” This creed established the equality and co-eternity of the Father and the Son as orthodox Christian doctrine.

Arius himself was condemned, and his writings were ordered to be burned. However, Arianism would continue to influence parts of the church and provoke further debates for decades, even after the council.
