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 [the Son] 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 Arius's real following was limited to Alexandria. For example, his book, The Thalia, circulated only locally. However, after Alexander excommunicated him, he appealed to the Eastern Church and found support. He was supported by Eusebius of Nicomedia, who effectively was the leader of the Eastern Church. Arius was also supported by
Eusebius of Caesarea, the church historian and theologian, one of the most influential authors of the fourth century. "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, 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, 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, who baptized Constantine the Great.
First Council of Nicaea , with Arius depicted beneath the feet of the Emperor Constantine and the
bishops The Christological debate could no longer be contained within the Alexandrian
diocese. By the time Bishop Alexander finally acted against Arius, Arius's doctrine had spread far beyond his own see; it had become a topic of discussion—and disturbance—for the entire Church. The Church was now a powerful force in the Roman world, with Emperors
Licinius and
Constantine I having legalized it in 313 through the
Edict of Milan. Emperor Constantine had taken a personal interest in several ecumenical issues, including the
Donatist controversy in 316, and he wanted to bring an end to the Christological dispute. To this end, the emperor sent
Hosius, bishop of Córdoba to investigate and, if possible, resolve the controversy. Hosius was armed with an open letter from the Emperor: "Wherefore let each one of you, showing consideration for the other, listen to the impartial exhortation of your fellow-servant." However, as the debate continued to rage despite Hosius's efforts, Constantine in AD 325 took an unprecedented step: he called a
council to be composed of church
prelates from all parts of the empire to resolve this issue, possibly at Hosius's recommendation. "Around 250–300 attended, drawn almost entirely from the eastern half of the empire."
Pope Sylvester I, himself too aged to attend, sent two priests as his delegates. Arius himself attended the council, as did his bishop, Alexander. Also there were
Eusebius of Caesarea, Eusebius of Nicomedia and the young deacon
Athanasius, who would become the champion of the Trinitarian view ultimately adopted by the council and spend most of his life battling Arianism. Before the main conclave convened, Hosius initially met with Alexander and his supporters at
Nicomedia. The council was presided over by the emperor himself, who participated in and even led some of its discussions. that the Son was of the same essence (
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
Divinity was greater than the Son's, and that the Son was under God the Father, and not co-equal or co-eternal with him. In the
hagiography of
Nicholas of Myra, debate at the council became so heated that at one point, Nicholas struck Arius across the face. The majority of the bishops ultimately agreed upon a creed, known thereafter as the
Nicene Creed. 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 ==
