Arius

Arius was a religious leader who lived during a transformative era for the Roman Empire. He was born around 250 or 256 and died in 336. A man of Berber descent, he was the son of Ammonius. By the year 313, Arius served as a presbyter in the Baucalis district of Alexandria. A presbyter is a specific type of church leader.

Descriptions of his appearance suggest he was a very tall man. He was known for wearing a short cloak and a sleeveless tunic. Observers noted that he spoke gently and could be very persuasive. While his opponents often attacked his character, some modern scholars view him as an original and resourceful thinker.

Arius is most famous for the theological ideas known as Arianism. This belief system centers on the relationship between God the Father and Jesus Christ. Arius taught that God the Father was the only truly eternal and infinite being. He argued that the Son was created directly by the Father before anything else existed. Because the Son was created, Arius believed there was a time when the Son did not exist. This concept is called radical subordinationism, meaning the Son holds a lower position than the Father.

To understand his views, one must look at the specific theological terms used in the fourth century. Arius believed the Son possessed divinity only through the permission and power of the Father. He did not believe the Son was coeternal, or existing forever alongside the Father. This was a major point of disagreement with leaders like Athanasius of Alexandria. Athanasius argued for a Homoousian conception, which suggests the Father and the Son share the same substance.

The term "God" at that time was also used differently than it is today. It could refer to different levels of divinity rather than just one sole being.

This theological disagreement became known as the Arian Controversy. It began around 318 when Arius criticized his bishop, Alexander of Alexandria. Arius felt Alexander was blurring the distinctions between the Father and the Son. This tension arrived shortly after the Roman Empire legalized Christianity through the Edict of Milan in 313. Emperor Constantine the Great wanted to resolve these religious divisions to maintain imperial unity. To do this, he organized the First Council of Nicaea in 325.

At the Council of Nicaea, the gathered leaders formally condemned Arianism. They favored the Homoousian view and produced the Nicene Creed. This document was specifically written to act as an anti-Arian statement of faith. Following the council, Emperor Constantine ordered the burning of Arius's writings. Because of this, very little of Arius's actual work survives today. We only possess three of his letters and fragments of his theological work, the Thalia.

Most of what we know about his specific arguments comes from the writings of his enemies, such as Athanasius.

Historians continue to debate the exact role Arius played in these events. Some see him as the sole founder of a new sect. However, others like Rowan Williams suggest he was not a deliberate radical. Instead, he may have been a theological conservative within the Alexandrian tradition. Historian Richard Hanson described Arius as a "spark" that ignited a crisis that was already gathering. This suggests that the debate was part of a much larger movement within the Church.

Despite the decisions made at Nicaea, Arianism did not vanish immediately. Arian churches persisted for several centuries across many regions. They were established in parts of Europe, the Middle East, and North Africa. In Europe, they were particularly present in various Germanic kingdoms. These groups were eventually suppressed between the fifth and seventh centuries. This happened through either military conquest or through the voluntary conversion of kings.

Even today, the legacy of this debate is visible in the foundational documents of many traditions.
