Arianism is the theological teaching of Arius (ca. AD 250–336), a Christian presbyter from Alexandria, Egypt, concerning the relationship of the entities of the Trinity ('God the Father', 'God the Son' and 'God the Holy Spirit') and the precise nature of the Son of God. Deemed a heretic by the First Council of Nicaea of 325, Arius was later exonerated in 335 at the First Synod of Tyre[1], and then pronounced a heretic again after his death at the First Council of Constantinople of 381.[2] The Roman Emperors Constantius II (337-361) and Valens (364-378) were Arians or Semi-Arians.
Arianism is defined as those teachings attributed to Arius which are in opposition to mainstream Trinitarian Christological dogma, as determined by the first two Ecumenical Councils and currently maintained by the Roman Catholic Church, the Eastern Orthodox Churches and most Protestant Churches. "Arianism" is also often used to refer to other nontrinitarian theological systems of the 4th century, which regarded Jesus Christ—the Son of God, the Logos—as either a created being (as in Arianism proper and Anomoeanism), or as neither uncreated nor created in the sense other beings are created (as in Semi-Arianism).
Arius posed the question: "Is Jesus unbegotten?"[citation needed] In answer, he taught that God the Father and the Son did not exist together eternally. Further, Arius taught that the pre-incarnate Jesus was a divine being created by (and therefore inferior to) God the Father at some point, before which the Son did not exist.[3] In English-language works, it is sometimes said that Arians believe that Jesus is or was a "creature"; in the sense of "created being". That doctrine that Arius wrote was based on Scriptures such as John 14:28 where Jesus says that the father is "greater than I", to John 17:20-26, where Jesus asks that the Apostles become "one as we are one" so that all of them, including Jesus, and God become one. This is interpreted as indicating that the oneness refers to a unity of divine thought and will, and not a unity in a co-eternal Trinity.[citation needed]
Of all the various disagreements within the Christian Church, the Arian controversy has held the greatest force and power of theological and political conflict, with the possible exception of the Protestant Reformation. The conflict between Arianism and Trinitarian beliefs was the first major doctrinal confrontation in the Church after the legalization of Christianity by the Roman Emperor Constantine I.[citation needed]
The controversy over Arianism began to rise in the late 3rd century and extended over the greater part of the 4th century and involved most church members, simple believers, priests and monks as well as bishops, emperors and members of Rome's imperial family. Yet, such a deep controversy within the Church could not have materialized in the 3rd and 4th centuries without some significant historical influences providing the basis for the Arian doctrines. Most orthodox or mainstream Christian historians define and minimize the Arian conflict as the exclusive construct of Arius and a handful of rogue bishops engaging in heresy. Of the roughly three hundred bishops in attendance at the Council of Nicea, only three bishops did not sign the Nicene Creed. However, to minimize the extent of Arianism ignores the fact that extremely prominent Emperors such as Constantius II, and Valens were Arians, as well as prominent Gothic, Vandal, and Lombard warlords both before and after the fall of the Western Roman Empire, and that none of these groups was out of the mainstream of the Roman Empire in the 4th century.[citation needed]
After the dispute over Arius politicized the debate and a catholic or general solution to the debate was sought, with a great majority holding to the Trinitarian position, the Arian position was declared officially to be heterodox. Lucian of Antioch had contended for a christology very similar to what would later be known as Arianism and is thought to have contributed much to its development. Arius was a student of Lucian's private academy in Antioch. The Ebionites, among other early Christian groups, may also have maintained similar doctrines that can be associated with formal Lucian and Arian Christology.[citation needed]
While Arianism continued to dominate for several decades even within the family of the Emperor, the Imperial nobility, and higher-ranking clergy, in the end it was Trinitarianism which prevailed in the Roman Empire at the end of the 4th century. Arianism, which had been taught by the Arian missionary Ulfilas to the Germanic tribes, was dominant for some centuries among several Germanic tribes in western Europe, especially Goths and Lombards (and significantly for the late Empire, the Vandals), but ceased to be the mainstream belief by the 8th century. Trinitarianism remained the dominant doctrine in all major branches of the Eastern and Western Church and later within Protestantism, although there have been several anti-Trinitarian movements, some of which acknowledge various similarities to classical Arianism.[citation needed]
Because most extant written material on Arianism was written by its opponents, the nature of Arian teachings is difficult to define precisely today. The letter of Auxentius,[4] a 4th-century Arian bishop of Milan, regarding the missionary Ulfilas, gives the clearest picture of Arian beliefs on the nature of the Trinity: God the Father ("unbegotten"), always existing, was separate from the lesser Jesus Christ ("only-begotten"), born before time began and creator of the world. The Father, working through the Son, created the Holy Spirit, who was subservient to the Son as the Son was to the Father. The Father was seen as "the only true God". 1 Corinthians 8:5-6 was cited as proof text:
Indeed, even though there may be so-called gods in heaven or on earth — as in fact there are many gods and many lords — yet for us there is one God (Gk. theos - θεος), the Father, from whom are all things and for whom we exist, and one Lord (kyrios - κυριος), Jesus Christ, through whom are all things and through whom we exist.—NRSV
A letter from Arius to the Arian Eusebius of Nicomedia succinctly states the core beliefs of the Arians:
Some of them say that the Son is an eructation, others that he is a production, others that he is also unbegotten. These are impieties to which we cannot listen, even though the heretics threaten us with a thousand deaths. But we say and believe and have taught, and do teach, that the Son is not unbegotten, nor in any way part of the unbegotten; and that he does not derive his subsistence from any matter; but that by his own will and counsel he has subsisted before time and before ages as perfect God, only begotten and unchangeable, and that before he was begotten, or created, or purposed, or established, he was not. For he was not unbegotten. We are persecuted, because we say that the Son has a beginning, but that God is without beginning.—Peters,
In 321, Arius was denounced by a synod at Alexandria for teaching a heterodox view of the relationship of Jesus to God the Father. Because Arius and his followers had great influence in the schools of Alexandria—counterparts to modern universities or seminaries—their theological views spread, especially in the eastern Mediterranean.
