# Arianism

<!-- type: concept | created: 2026-04-28 | updated: 2026-04-28 -->

## Intro

In the early 300s, a priest in Alexandria named Arius started teaching that Jesus, the Son of God, was a created being. The highest, the firstborn, the agent through whom God made the rest of creation, but still a creature with a beginning. The famous slogan: *there was when he was not.* In other words, the Son had not always existed; the Father brought him into being.

If that sounds like a small adjustment to orthodox Christianity, it is not. It is the difference between *Jesus is God* and *Jesus is the most exalted thing God ever made.* The first is worship. The second is creature-cult. The whole question of who Jesus is rides on it.

The crisis tore the church apart for most of the fourth century. The First Council of Nicaea in 325 condemned Arianism and produced the Nicene Creed (the one that says Jesus is *begotten, not made, of one substance with the Father*). But the controversy did not actually end there. It dragged on through Constantine's sons, through Athanasius's repeated exiles, and through several softer compromises (semi-Arianism, Homoianism, Eunomianism) before finally being settled at Constantinople in 381.

The page traces the historical sequence, the biblical texts Arians appealed to ([John 14:28](/codex/john-14-28/), [Mark 13:32](/codex/mark-13-32/), [Proverbs 8:22](/codex/proverbs-8-22/), [Colossians 1:15](/codex/colossians-1-15/)), the orthodox response to each, and the modern groups that hold positions structurally similar to Arianism today (most clearly Jehovah's Witnesses, in softer forms some streams of Latter-day Saint and liberal Protestant theology).

## In full

The 4th-century Christological position associated with Arius (c. 256-336), a presbyter of Alexandria, that the Son of God is the highest of all creatures, divine in a derivative sense, but ontologically distinct from and subordinate to the Father, having been brought into existence out of nothing by the Father's will before all other creation. The slogan most famously associated with the position, "there was when He was not" (*ēn pote hote ouk ēn*), denies the eternal coexistence of the Son with the Father. Arianism precipitated the largest doctrinal crisis of the early church, was condemned at the First Council of Nicaea (325), continued in modified forms (semi-Arianism, Homoianism, Eunomianism) for much of the 4th century, and persists in modern restorationist movements that deny Christ's full deity, most notably Jehovah's Witnesses (Watchtower theology) and (in a softer form) some currents of Latter-day Saint and liberal-Protestant Christology.

## Core claim

- **The Son is a creature.** The Son is not eternal; there was a "when" when the Son did not exist. The Father alone is *agennētos* (unbegotten / uncreated).
- **The Son was made out of nothing.** *Ex ouk ontōn*, out of nonbeing, by the Father's will. The Son's beginning preceded the rest of creation, but it is a beginning nonetheless.
- **The Son is of a different substance from the Father.** Not *homoousios* (same substance) and (in stricter Arianism) not even *homoiousios* (similar substance). Eunomius (later in the 4th c.) sharpens this into *anomoios*, *unlike* the Father.
- **The Son is divine in a derivative sense.** As the firstborn of creation and the agent through whom God made all other things, the Son is properly called "god", but as a creature elevated to that status, not as God in the strict ontological sense.
- **Subordination is ontological, not merely economic.** The Son's submission to the Father (e.g. [John 14:28](/codex/john-14-28/)) reflects the Son's lesser nature, not merely an incarnational role.

## Biblical appeals

Arians read the NT subordinationist data as strong evidence that the Son is genuinely lesser than the Father:

- [John 14:28](/codex/john-14-28/) ("my Father is greater than I")
- [Mark 13:32](/codex/mark-13-32/) (the Son does not know the day or the hour)
- [Prov 8:22](/codex/proverbs-8-22/) (in the LXX: "The LORD created [*ektisen*] me at the beginning of his way"), Arius read Wisdom in [Prov 8](/codex/proverbs-8/) as the pre-incarnate Son
- [Col 1:15](/codex/colossians-1-15/) ("the firstborn of all creation", *prōtotokos pasēs ktiseōs*)
- [John 1:18](/codex/john-1-18/) ("only-begotten", *monogenēs*), read as a temporal beginning of begetting
- [1 Cor 15:28](/codex/1-corinthians-15-28/) (the Son finally subjected to the Father)
- [John 17:3](/codex/john-17-3/) ("the only true God" applied to the Father, with [Jesus](/codex/jesus/) apparently distinguished from this category)
- [1 Tim 2:5](/codex/1-timothy-2-5/) ("one God... and one mediator" with the *man* Christ Jesus)

The orthodox response is that *prōtotokos* in [Col 1:15](/codex/colossians-1-15/) denotes preeminence, not creation; *monogenēs* in [John 1:18](/codex/john-1-18/) denotes uniqueness of relation, not temporal origin; the LXX of [Prov 8:22](/codex/proverbs-8-22/) is contested (the Hebrew is *qanani*, "possessed me" / "begot me"); and the subordination texts refer to the incarnate Son's role / human nature, not to His eternal being.

## Historical development

- **Origins (c. 318-325).** Arius, a presbyter of the Baucalis church in Alexandria, came into conflict with his bishop Alexander over the relation of the Son to the Father. Arius's *Thalia* (a hymnic statement of his theology, surviving in fragments) crystallized the position. The conflict spread quickly across the Eastern empire.
- **First Council of Nicaea (325).** Convened by Constantine, attended by ~250-300 bishops. The Nicene Creed (325) responded with three pivotal phrases: the Son is "begotten, not made" (*gennēthenta ou poiēthenta*); "of one substance with the Father" (*homoousion tō Patri*); and an explicit anathema on "those who say there was when He was not, and that before being begotten He was not, and that He came to be from things that were not, or who declare the Son of God to be of a different essence (*hypostasis*) or substance (*ousia*)." Arius and a small minority refused to subscribe and were exiled.
- **The mid-4th century crisis (325-381).** Despite Nicaea, Arian and semi-Arian parties dominated much of the imperial church for decades, especially under Constantius II. [Athanasius](/codex/athanasius/) of Alexandria, exiled five times across 17 years, became the preeminent defender of Nicaea ("*Athanasius contra mundum*"). The party landscape: strict Arians (Anomoeans / Eunomians: Son is *unlike* the Father), Homoians (Son is *like* the Father, no substance language), Semi-Arians (Homoiousians: Son is of *similar* substance), Nicenes (*homoousios*: Son is of *same* substance).
- **The Cappadocian settlement and Constantinople (381).** Basil of Caesarea, [Gregory of Nazianzus](/codex/gregory-of-nazianzus/), and [Gregory of Nyssa](/codex/gregory-of-nyssa/) rearticulated Nicene faith in the *one ousia / three hypostases* grammar that gathered the Eastern majority back to Nicaea. The First Council of Constantinople (381) confirmed Nicaea, expanded the creed (the form Christians today recite as the "Nicene Creed" is properly the Niceno-Constantinopolitan), and added explicit Trinitarian language about the Spirit. Arianism persisted among the Germanic tribes (Visigoths, Vandals, Lombards, Ostrogoths), evangelized largely by Ulfilas (an Arian missionary), into the 6th-7th centuries.
- **Modern revivals.** The Socinians of the Reformation era anticipated modern non-Trinitarian Christologies. Charles Taze Russell's Watch Tower Bible and Tract Society (later Jehovah's Witnesses) revived a substantively Arian Christology in the late 19th c., identifying the pre-incarnate Christ as the archangel Michael, a created spirit being. Some currents of Latter-day Saint, Christadelphian, and liberal-Protestant Christology hold variants. The Evangelical Theological Society (ETS) has hosted ongoing controversy about so-called *eternal functional subordination* (EFS / ERAS) of the Son, a position critics call "neo-Arian" or "neo-subordinationist," though defenders insist they affirm full ontological equality and only functional / role subordination.

## Tensions

- **Subordination vs subordinationism.** All sides agree the incarnate Son submits to the Father in the economy of salvation. The dispute is whether this submission is *only economic* (classical orthodoxy) or *ontological / eternal* (Arian and semi-Arian positions; some EFS proponents). The line between licit "ordering" within the Trinity and illicit subordinationism is contested.
- **The Wisdom-Christology of [Proverbs 8](/codex/proverbs-8/).** The translation of [Prov 8:22](/codex/proverbs-8-22/), *qanah* in Hebrew can mean "create" or "acquire / possess / beget", became central to the Nicene-vs-Arian exegesis and is still discussed.
- **What "monogenēs" and "prōtotokos" mean.** Whether *monogenēs* (e.g. [John 1:14](/codex/john-1-14/); [John 1:18](/codex/john-1-18/)) means "only-begotten" (with temporal connotation) or "unique / one-of-a-kind" (with no temporal claim) is a long-running translation debate.
- **The Watchtower NWT translation.** The New World Translation's rendering of [John 1:1](/codex/john-1-1/) ("the Word was *a* god") is contested; the *anarthrous theos* in the predicate is read by JW translators as indefinite, by mainstream scholarship (Wallace, Harris) as qualitative.
- **Whether modern "Arianism" is the same as 4th-c. Arianism.** Watchtower theology shares Arianism's denial of the Son's eternal coexistence with the Father and the *homoousios*, but maps Christ to Michael (a unique move not in 4th-c. Arianism). Whether the label is precise or polemical is debated.

## Common questions this page answers

**Q: Wasn't Arius right that the Son is a creature?**

No; Arius's *"there was when He was not"* contradicts the canonical NT ([John 1:1-3](/codex/john-1-1-3/), *"in the beginning was the Word, and the Word was with God, and the Word was God... apart from Him nothing came into being"*) and the unanimous pre-Nicene Christological reading. Nicaea (325) ruled it out as heretical; the Arian deployment survives in modern Jehovah's Witnesses and Islam.

**Q: Who was Arius and what did he teach?**

Arius was a fourth-century presbyter at the Baucalis church in Alexandria (c. 256-336) who taught that the Son of God was the highest creature, brought into existence out of nothing by the Father's will before the rest of creation. His slogan *"there was when He was not"* denied the eternal coexistence of the Son with the Father.

**Q: What did the Council of Nicaea actually decide?**

Nicaea (325) condemned Arianism and produced the Nicene Creed, which says the Son is *"begotten, not made, of one substance (homoousios) with the Father"* and anathematizes anyone who says *"there was when He was not."* See [Trinity](/codex/trinity/) for the orthodox doctrine Nicaea defended.

**Q: Are Jehovah's Witnesses Arians?**

Substantively yes; Watchtower theology denies the Son's eternal coexistence with the Father and rejects *homoousios*, which makes it structurally Arian. The Watchtower's unique move (identifying the pre-incarnate Christ as the archangel Michael) is not in fourth-century Arianism. See [Jehovahs Witnesses](/codex/jehovahs-witnesses/).

**Q: Doesn't [John 14:28](/codex/john-14-28/) ("the Father is greater than I") prove Arianism right?**

No; the subordinationist texts ([John 14:28](/codex/john-14-28/), [Mark 13:32](/codex/mark-13-32/), [1 Cor 15:28](/codex/1-corinthians-15-28/)) refer to the incarnate Son's role and human nature, not to His eternal being. The orthodox reading distinguishes economic submission (in the work of salvation) from ontological lesser-ness, which Arianism affirms.
