nor Lord/Master). 1 Corinthians 8:5–6 was cited as proof text: The creed of Arian Ulfilas (c. 311–383), which concludes the above-mentioned letter by Auxentius, distinguishes God the Father ("unbegotten"), who is the only true God, from Son of God ("only-begotten"), who is Lord/Master; and the Holy Spirit, the illuminating and sanctifying power, who is neither God the Father nor Lord/Master: A letter from Arius (c. 250–336) to the Arian Eusebius of Nicomedia (died 341) states the core beliefs of the Arians: Principally, the dispute between Trinitarianism and Arianism was about: has the Son always existed eternally with the Father or was the Son begotten at a certain time in the past? is the Son equal to the Father or subordinated to the Father? For Constantine, these were minor theological points that stood in the way of uniting the Empire, but for the theologians, it was of huge importance; for them, it was a matter of salvation. For the theologians of the 19th century it was already obvious that in fact Arius and Alexander/Athanasius did not have much to quarrel about, the difference between their views was very small, and that the end of the fight was by no means clear during their quarrel, both Arius and Athanasius suffering a great deal for their own views. Arius was the father of Homoiousianism and Alexander the father of Homoousianism, which was championed by Athanasius. For those theologians it was clear that Arius, Alexander and Athanasius were far from a true doctrine of Trinity, which developed later, historically speaking. Guido M. Berndt and Roland Steinacher state clearly that the beliefs of Arius were acceptable ("not especially unusual") to a huge number of orthodox clergy; this is the reason why such a major conflict was able to develop inside the Church, since Arius's theology received widespread sympathy (or at least was not considered to be overly controversial) and could not be dismissed outright as individual heresy. Homoian Arianism Arianism had several different variants, including Eunomianism and Homoian Arianism. Homoian Arianism is associated with Acacius and Eudoxius. Homoian Arianism avoided the use of the word ousia to describe the relation of Father to Son, and described these as "like" each other. Hanson lists twelve creeds that reflect the Homoian faith: The Second Sirmian Creed of 357 The Creed of Nice (Constantinople) 360 The creed put forward by Acacius at Seleucia, 359 The Rule of Faith
