Arianism - Beliefs

Beliefs

Because virtually all 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, 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". First Corinthians 8:5-8:6 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. —Theodoret: Arius's Letter to Eusebius of Nicomedia, translated in Peters' Heresy and Authority in Medieval Europe, p. 41
