I agree with that.
It is a mix-up of different beliefs and cultures.
i.e. greek/roman and israelite/jewish
In the Jewish faith, many prophets and saints are referred to as 'sons of God' .. meaning 'special' as in very close to God
In Greek mythology/cultures, they had trinities of gods, which is actually a pagan concept..
So 'son of God' takes on a different meaning.
The Romans were happy about that and so encouraged and enforced such belief.
..they clearly saw Judaism as a threat .. they destroyed the temple in Jerusalem ..oh well..
The term Son of God in reference to the Messiah appears in the popular mind after the Roman occupation. The popular concept of the Messiah in this era was as a military leader who would liberate Israel from Roman occupation and bring in the messianic age of a restored Jewish kingdom. The Messiah as a military figure was already traditional due to the repeated foreign oppression of the Jewish people but now it was more explicit and imminently expected.
The connection between the term Son of God and this view of the Messiah is based on scripture.
Psalm 2
7 I will proclaim the Lord’s decree:
He said to me, “You are my son;
today I have become your father.
8 Ask me,
and I will make the nations your inheritance,
the ends of the earth your possession.
9 You will break them with a rod of iron;
you will dash them to pieces like pottery.”
In Mark we see the high priest ask Jesus if he is the Son of God. Jesus responds that he is and amplifies this with an apocalyptic reference from Daniel.
Mark 14
61 …Again the high priest asked him, “Are you the Christ, the Son of the Blessed?” 62 And Jesus said, “I am, and you will see the Son of Man seated at the right hand of Power, and coming with the clouds of heaven.”
Jesus is then turned over to the Romans with the charge that he claims to be the King of the Jews. This is not the theological Son of God as per Paul that is meant. This is the revolutionary Son of God of popular messianic sentiments who would expel the Romans and restore a Jewish kingdom.
The Pauline notion of a divine Son of God and John’s divine Logos use language and descriptive references straight out of Philo of Alexandria. Philo was a Jew who was intrigued by the Platonic view of God being so superior and pure that he would never ‘get his hands dirty’ creating the impure world. In Platonism, this is the job of the demiurge, an intermediate divine entity. Philo’s Son of God / Logos is this entity but described in a way that it is really just God himself, or maybe a super special angel. Philo is rather mysterious on this point, dancing around the implications of importing Greek polytheism into Jewish monotheism. So, in this sense, the origins of the Trinity can be traced to Greek philosophy. But not mythology.
The formal notion of a divine Trinity does not appear for another hundred years and its meaning is debated for centuries after. Paul speaks of Father, Son and Holy Spirit but it is not formalized in any fashion. The Pauline Holy Spirit does not appear to be any different from the Jewish
ruach, the breath of God which is not distinct from God himself.
I seriously doubt that the Romans had any interest in Christian theology. And the idea of a triad of gods would not sit well with the Roman mandate of the Imperial Cult, formally sacrificing to the divine Emperors (the ‘ancestral gods’, not necessarily the current Emperor) as a symbol of allegiance to Roman. It is the refusal to do this that gave Christians such a bad name among the Romans. They were seen as opposed to Roman rule and therefore to civilization.
The ever-practical Romans exempted Jews from the requirement to sacrifice because the trouble it would cause would be too costly in terms of military expenses and interrupted tax revenues. But to identify one’s self as a Jew required paying the Temple Tax, which in the post-Temple period went into Roman coffers, which they saw as a reasonable substitute for sacrifice. Like I said, practical. Later Christians were just about entirely separated from Judaism and refused to identify themselves as such.
According to Josephus, Titus did not want the Temple destroyed. The fire started during the fighting and quickly got out of control. Recall that not too long before Caligula wanted his statue placed in the Temple. It would have been a great ‘prize of war’ to make the Jewish Temple into a pagan one, especially since it had earlier been remodeled and expanded by the Roman puppet Herod.
