, who stated that "Arius' role in 'Arianism' was not that of the founder of a sect. It was not his individual teaching that dominated the mid-century eastern Church." Richard Hanson writes that Arius' specific espousal of subordinationist theology brought "into unavoidable prominence a doctrinal crisis which had gradually been gathering
..He was the spark that started the explosion. But in himself he was of no great significance." The association between Arius and the theology titled after him has been argued to be a creation "based on the polemic of Nicene writers" such as Athanasius of Alexandria, a Homoousian.
Early life and personality
Reconstructing the life and doctrine of Arius has proven to be a difficult task.
Arius was of

descent. His father's name is given as Ammonius.
Hanson says that "Arius very probably had at some time studied with Lucian of Antioch" because he refers to somebody else as "truly a ''fellow''-disciple of Lucian." But Williams questions whether "we should assume from the one word in Arius' letter that he had actually been Lucian's student."
In the past, many writers have assumed that our Arius is the same as the Arius who was involved in the
Melitian schism, "who had an outward appearance of piety, and ... was eager to be a teacher." However, after several pages of detailed analysis, Williams concludes that "the Melitian Arius ... melt(s) away under close investigation."
In 313, Arius was made

of the Baucalis district in Alexandria.
Arius' views have always been "represented as ... some hopelessly defective form of belief." Contrary to this view, Rowan Williams recently concluded that Arius is "a thinker and exegete of resourcefulness, sharpness and originality."
Although his character has been severely assailed by his opponents, Arius appears to have been a man of personal

achievement, pure morals, and decided convictions.
"He was very tall in stature, with downcast countenance ... always garbed in a short cloak and sleeveless tunic'';'' he spoke gently, and people found him persuasive and flattering."
It is traditional to claim that Arius was a deliberate radical, breaking away from the 'orthodoxy' of the church fathers. However:
"A great deal of recent work seeking to understand Arian spirituality has, not surprisingly, helped to demolish the notion of Arius and his supporters as deliberate radicals, attacking a time-honoured tradition."
"Arius was a committed theological conservative; more specifically, a conservative Alexandrian."
Arius' writings
Very little of Arius' writing has survived. "As far as his own writings go, we have no more than three letters, (and) a few fragments of another." The three are:
# The confession of faith Arius presented to Alexander of Alexandria,
# His letter to Eusebius of Nicomedia, and
# The confession he submitted to the emperor."
"The Thalia is Arius' only known theological work" but "we do not possess a single complete and continuous text." We only have extracts from it in the writings of Arius' enemies, "mostly from the pen of Athanasius of Alexandria, his bitterest and most prejudiced enemy."
Emperor Constantine ordered their burning while Arius was still living but R.P.C. Hanson concluded that so little survived because "the people of his day, whether they agreed with him or not, did not regard him (Arius) as a particularly significant writer."
Those works which have survived are quoted in the works of churchmen who denounced him as a

Bishop R.P.C. Hanson wrote:
"Athanasius, a fierce opponent of Arius ... certainly would not have stopped short of ''misrepresenting'' what he said." "Athanasius... may be suspected of pressing the words ''maliciously'' rather further than Arius intended."
Archbishop Rowan Williams agrees that Athanasius applied "unscrupulous tactics in polemic and struggle."
Arian controversy
Beginnings
The
Diocletianic Persecution (Great Persecution) of AD 303–313 was Rome's final attempt to limit the expansion of Christianity across the empire. That persecution came to an end when Christianity was legalized with Galerius' Edict of Toleration in 311 followed by Constantine's Edict of Milan in 313, after Emperor Constantine himself had become a Christian. The Arian Controversy began only 5 years later in 318 when Arius, who was in charge of one of the churches in Alexandria, publicly criticized his bishop Alexander for "carelessness in blurring the distinction of nature between the Father and the Son by his emphasis on eternal generation".
The
Trinitarian historian
Socrates of Constantinople reports that Arius sparked the controversy that bears his name when
Alexander of Alexandria, who had succeeded
Achillas as the Bishop of
Alexandria

, gave a sermon stating the similarity of the Son to the Father. Arius interpreted Alexander's speech as being a revival of
Sabellianism, condemned it, and then argued that "if the Father begat the Son, he that was begotten had a beginning of existence: and from this it is evident, that there was a time when the Son was not. It therefore necessarily follows, that he

had his substance from nothing." This quote describes the essence of Arius's doctrine.
Socrates of Constantinople believed that Arius was influenced in his thinking by the teachings of
Lucian of Antioch, a celebrated Christian teacher and martyr. In a letter to Patriarch
Alexander of Constantinople, Arius's bishop,
Alexander of Alexandria, wrote that Arius derived his theology from Lucian. The express purpose of the letter was to complain about the doctrines that Arius was spreading, but his charge of heresy against Arius is vague and unsupported by other authorities. Furthermore, Alexander's language, like that of most controversialists in those days, is quite bitter and abusive. Moreover, even Alexander never accused Lucian of having taught Arianism.
Supporters
It is traditionally taught that Arius had wide support in the areas of the Roman Empire. But it now seems his supporters were limited to Egypt and Alexandria:
The controversy had spread from Alexandria into almost all the African regions and was considered a disturbance of the public order by the Roman Empire. (Eusebius of Caesarea in The Life of Constantine).
"The ''Thalia'' appears ... to have circulated only in Alexandria; what is known of him elsewhere seems to stem from Athanasius' quotations."
He also had the support of perhaps the two most important church leaders of that time:
Eusebius of Nicomedia
Eusebius of Nicomedia "was a supporter of Arius as long as Arius lived." "The conventional picture of Eusebius is of an unscrupulous intriguer." "This is of course because our knowledge of Eusebius derives almost entirely from the evidence of his bitter enemies." Hanson mentions several instances displaying Eusebius' integrity and courage and concludes:
"Eusebius certainly was a man of strong character and great ability" (page 29). "It was he who virtually took charge of the affairs of the Greek speaking Eastern Church from 328 until his death" (page 29). He encouraged the spread of the Christian faith beyond the frontiers of the Roman Empire. The version of the Christian faith which the missionaries spread was that favoured by Eusebius and not Athanasius. This serves as evidence of his zeal."
Eusebius of Caesarea
"Eusebius, bishop of Caesarea in Palestine
he church historianwas certainly an early supporter of Arius." "He was universally acknowledged to be the most scholarly bishop of his day." "Eusebius of Caesarea ... was one of the most influential authors of the fourth century." "Neither Arius nor anti-Arians speak evil of him." "He was made bishop of Caesarea about 313, (and) attended the Council of Nicaea in 325."
"We cannot accordingly describe Eusebius (of Caesarea) as a formal Arian in the sense that he knew and accepted the full logic of Arius, or of Asterius' position. But undoubtedly, he approached it nearly."
Origen and Arius
Like many third-century Christian scholars, Arius was influenced by the writings of
Origen
Origen of Alexandria (), also known as Origen Adamantius, was an Early Christianity, early Christian scholar, Asceticism#Christianity, ascetic, and Christian theology, theologian who was born and spent the first half of his career in Early cent ...
, widely regarded as the first great theologian of Christianity. However, while both agreed on the subordination of the Son to the Father, and Arius drew support from Origen's theories on the ''
Logos
''Logos'' (, ; ) is a term used in Western philosophy, psychology and rhetoric, as well as religion (notably Logos (Christianity), Christianity); among its connotations is that of a rationality, rational form of discourse that relies on inducti ...
'', the two did not agree on everything. For example:
* Hanson refers several times to Origen's teaching that the Son always existed, for example, "Origen's doctrine of the ''eternal generation'' of the Son by the Father." To contrast this with what Arius taught, Hanson states that Arius taught that 'there was a time when he did not exist'."
* "Arius in the ''Thalia'' sees the Son as praising the Father in heaven; Origen generally avoids language suggesting that the Son ''worships'' the Father as God."
Hanson concluded:
"Arius probably inherited some terms and even some ideas from Origen, ... he certainly did not adopt any large or significant part of Origen's theology." "He was not without influence from Origen, but cannot seriously be called an Origenist."
However, because Origen's theological speculations were often proffered to stimulate further inquiry rather than to put an end to any given dispute, both Arius and his opponents were able to invoke the authority of this revered (at the time) theologian during their debate.
Divine but not fully divine
Arius emphasized the supremacy and uniqueness of God the Father, meaning that the Father alone is infinite and eternal and almighty, and that therefore the Father's divinity must be greater than the Son's. Arius maintained that the Son possessed neither the eternity nor the true divinity of the Father but was rather made "God" only by the Father's permission and power.
"Many summary accounts present the Arian controversy as a dispute over whether or not Christ was divine." "It is misleading to assume that these controversies were about 'the divinity of Christ'." "Many fourth-century theologians (including some who were in no way anti-Nicene) made distinctions between being 'God' and being 'true God' that belie any simple account of the controversy in these terms."
"It must be understood that in the fourth century the word 'God' ''(theos, deus)'' had not acquired the significance which in our twentieth-century world it has acquired ... viz. the one and sole true God. The word could apply to many gradations of divinity and was not as absolute to Athanasius as it is to us."
Initial responses
The Bishop of Alexandria exiled the presbyter following a council of local priests. Arius's supporters vehemently protested. Numerous bishops and Christian leaders of the era supported his cause, among them
Eusebius of Nicomedia

homoousios) with the Father (or one in essence with the Father), and was eternally generated from that essence of the Father. Those who instead insisted that the Son of God came after God the Father in time and substance were led by Arius the presbyter. For about two months, the two sides argued and debated, with each appealing to Scripture to justify their respective positions. Arius argued for the supremacy of God the Father, and maintained that the Son of God was simply the oldest and most beloved creature of God, made from nothing, because of being the direct offspring. Arius taught that the pre-existent Son was God's first production (the very first thing that God actually ever did in his entire eternal existence up to that point), before all ages. Thus he insisted that only God the Father had no beginning, and that the Father alone was infinite and eternal. Arius maintained that the Son had a beginning. Thus, said Arius, only the Son was directly created and begotten of God; furthermore, there was a time that he had no existence. He was capable of his own free will, said Arius, and thus "were He in the truest sense a son, He must have come after the Father, therefore the time obviously was when He was not, and hence He was a finite being." Arius appealed to Scripture, quoting verses such as John 14:28: "the Father is greater than I", as well as Colossians 1:15: "the firstborn of all creation." Thus, Arius insisted that the Father's

. It included the word ''homoousios'', meaning "consubstantial", or "one in essence", which was incompatible with Arius's beliefs. On June 19, 325, council and emperor issued a circular to the churches in and around Alexandria: Arius and two of his unyielding partisans (Theonas and Secundus) were deposed and exiled to
Illyricum, while three other supporters—
Theognis of Nicaea, Eusebius of Nicomedia and Maris of Chalcedon—affixed their signatures solely out of deference to the emperor. The following is part of the ruling made by the emperor denouncing Arius's teachings with fervor.
Exile, return, and death
The homoousian party's victory at Nicaea was short-lived, however. Despite Arius' exile and the ostensible finality of the Council's decrees, the Arian controversy recommenced at once. When Bishop Alexander died in 327, Athanasius succeeded him, despite not meeting the age requirements for a hierarch. Still committed to pacifying the conflict between Arians and Trinitarians, Constantine gradually became more lenient toward those whom the Council of Nicaea had exiled.
Though he never repudiated the council or its decrees, the emperor ultimately permitted Arius (who had taken refuge in

First Synod of Tyre in 335 (though he was later recalled), and the Synod of Jerusalem the following year restored Arius to communion. The emperor directed Alexander of Constantinople to receive Arius, despite the bishop's objections; Bishop Alexander responded by earnestly praying that Arius might perish before this could happen.

Arius's doctrine
Introduction
In explaining his actions against Arius, Alexander of Alexandria wrote a letter to Alexander of Constantinople and Eusebius of Nicomedia (where the emperor was then residing), detailing the errors into which he believed Arius had fallen. According to Alexander, Arius taught:
Alexander also refers to Arius's poetical ''Thalia'':
Eusebius of Caesarea, in his famous book ''The Ecclesiastical History'' explains Arius' views as:
The Logos
The question of the exact relationship between the Father and the Son (a part of the theological science of

) had been raised some fifty years before Arius, when
Paul of Samosata was deposed in 269 for agreeing with those who used the word ''
homoousios'' (Greek for 'same substance') to express the relation between the Father and the Son. This term was thought at that time to have a
Sabellian tendency, though—as events showed—this was on account of its scope not having been satisfactorily defined. In the discussion which followed Paul's deposition,
Dionysius, the Bishop of Alexandria, used much the same language as Arius did later, and correspondence survives in which
Pope Dionysius blames him for using such terminology. Dionysius responded with an explanation widely interpreted as vacillating. The
Synod of Antioch
Beginning with three synods convened between 264 and 269 in the matter of Paul of Samosata, more than thirty councils were held in Antioch in ancient times. Most of these dealt with phases of the Arian and of the Christological controversies. For ...
, which condemned Paul of Samosata, had expressed its disapproval of the word ''homoousios'' in one sense, while Bishop Alexander undertook its defense in another. Although the controversy seemed to be leaning toward the opinions later championed by Arius, no firm decision had been made on the subject; in an atmosphere so intellectual as that of Alexandria, the debate seemed bound to resurface—and even intensify—at some point in the future.
Arius endorsed the following doctrines about the Son or the Word (''

, and his confession to Constantine. In addition, several letters addressed by others to Arius survive, together with brief quotations contained within the polemical works of his opponents. These quotations are often short and taken out of context, and it is difficult to tell how accurately they quote him or represent his true thinking.
The ''Thalia''
Arius's ''Thalia'' (literally, 'festivity', 'banquet'), a popularized work combining prose and verse and summarizing his views on the Logos, survives in quoted fragmentary form. In the ''Thalia'', Arius says that God's first thought was the creation of the Son, before all ages, therefore

, even if he did not exist eternally (lines 20–23); and endeavors to explain the ultimate incomprehensibility of the Father to the Son (lines 33–39). The two available references from this work are recorded by his opponent Athanasius: the first is a report of Arius's teaching in ''Orations Against the Arians'', 1:5–6. This paraphrase has negative comments interspersed throughout, so it is difficult to consider it as being completely reliable.
The second quotation appears on page 15 of the document ''On the Councils of Arminum and Seleucia'', also known as . This second passage, entirely in irregular verse, seems to be a direct quotation or a compilation of quotations; it may have been written by someone other than Athanasius, perhaps even a person sympathetic to Arius. This second quotation does not contain several statements usually attributed to Arius by his opponents, is in metrical form, and resembles other passages that have been attributed to Arius. It also contains some positive statements about the Son. But although these quotations seem reasonably accurate, their proper context is lost, so their place in Arius's larger system of thought is impossible to reconstruct.

The part of Arius's ''Thalia'' quoted in Athanasius's is the longest extant fragment. The most commonly cited edition of is by Hans-Georg Opitz. A translation of this fragment has been made by Aaron J. West, but based not on Opitz' text but on a previous edition: "When compared to Opitz' more recent edition of the text, we found that our text varies only in punctuation, capitalization, and one variant reading ( for , line 5)."
The Opitz edition with the West translation is as follows:
A slightly different edition of the fragment of the ''Thalia'' from is given by G.C. Stead, and served as the basis for a translation by R.P.C. Hanson. Stead argued that the ''Thalia'' was written in anapestic meter, and edited the fragment to show what it would look like in anapests with different line-breaks. Hanson based his translation of this fragment directly on Stead's text.
