You are still trying to get Hart to mean the opposite of what he said. Why not simply say you disagree with him over Arius representing the traditional view and Nicaea as the innovation, rather than try to distort what he said?
Hanson’s book is good. It is one the first books I read on the ‘Arian controversy’. It’s huge and has lots of detail. I no longer own a copy because I bought it for £20 and later sold it to make a profit at £100. It is now very scarce. If a cheap physical copy becomes available I’d buy it again.
Hanson is generally fair in his treatment and his overall assessment of pre-Nicene Christology contradicts a neat Trinitarian reading of the history of the dogma. Hanson is clear that the pre-Nicaea orthodoxy was subordinationism. This is most extensively elaborated in Origen but applies to all pre-Nicene Christian authors. Origen also clearly made numerous statements that are simply incompatible with later Trinitarian dogma, such as that the Word is a “secondary god” compared “the God”, calling Jesus a “creation”, and making numerous statements about Jesus being subordinate to God. It is true that Origen also taught a concept of “eternal generation” which later Trinitarians would exploit to bolster their view that Jesus is not a creation. But bearing in mind that Origen viewed Jesus as a creation and subordinate to God, it is appropriate to ask what Origen meant by his own terminology rather than the alternative meaning that later Trinitarians put on it. Origen apparently was concerned to emphasise that Jesus was not begotten at a point in time for reasons to do with his cosmology and therefore conceptualised it as an ongoing process. This in no way negates his numerous statements regarding Jesus’ junior status in relation to God and the gulf is honour, power and position that he perceived between God and Jesus.
Other key points to bear in mind include that later Trinitarians declared Origen a heretic because they recognised that the extensive writings of this preeminent pre-Nicene scholar was incompatible with their Trinitarian dogma. It is also crucial to note that the works of Origen that survive represent a tiny amount of what he wrote and that many of his works were suppressed or rewritten in order to conform with later Trinitarian dogma. You can claim this is not so - inevitably you will - but it is an extensively documented fact in the scholarly literature. Given the tampering with Origen’s work by later Trinitarians, it is in fact remarkable that crucial traces of his subordinationist Christology remains, and it can only mean that his views on this matter were so integral to his overall theology that it simply proved impossible for later Trinitarian dogmaticians to eradicate it completely.
