I've carried these questions from
@DerekhHikmah over from the 'Arian banquet verses' thread because I think they are worthwhile:
A two-part question.
As for 'what did he actually believe' – I'll answer that over on the 'banquet' thread. But for brevity here, we can reliably reconstruct his beliefs enough to pinpoint the actual elements of the dispute.
As for how he was represented, the answer to that is he was
personally grossly and viciously misrepresented and maligned, primarily by Athanasius, who goes at some length to destroy his name, reputation and the theology he was re-presenting, at some length and with great vitriol, as the father of 'Arianism' and the founder of a group of heretics he referred to as 'Ario-maniacs' (
Discourse 1 Against the Arians, para4)

The distinguishing feature is, of course, the presence of the apostles in the debate, but even from Acts 15 we can see the debate was discussed at some length, and opinions were divided.
We can assume some degree of resolution was arrived at, with James, Peter and Paul in agreement – but that did not end diversity of belief in the Church, much as 'traditional' historians would like to say that orthodoxy was established at this time.
So the process devolved to the nascent hierarchy of the Church – bishops, priests and deacons. This led to the synod as the manner of governance and determination. Because of geographical distances, etc., the respective bishops has a fair degree of autonomy and rules were established to ensure such. Having said that, there were influential catechetical schools, such as at Alexandria and Antioch.
A wide variety of concepts, as Scripture is nowhere near as prescriptive as we might like – by which I mean providing categorical answers to questions arising.
No. One of the big impediments at Nicaea was the fact that the term
homoousios does not appear in scripture, and the bishops were rather hoping that scripture itself would suffice to prevent conflict ... clearly it did not.
Theological waters are further muddied because the definitions of terms changed over time, so even when a term dies appear in scripture, such as
hypostasis, (three times in Hebrews and twice in 2 Corinthians) the manner in which the term came to be defined is not precisely in accord with the definition Paul or the author of Hebrews had in mind.
