I'm pretty familiar with the Original Testament. I'm certain that Moses and Samuel and such would have considered standard Christian Trinitarian theology and Jesus's divinity utter heresy. A complete breaking of the 1st Commandment, and Jesus's regular depiction in the Christian world breaking the 2nd.
It's no surprise to me that devout Jews completely rejected this pagan polytheism.

Polytheism ? - the Church condemned the heresy of tritheism many centuries ago.
Christians believe that God is triune: one God with three aspects - eternal mind and eternal thought, joined together by eternal love..
Jews worship the unseen God, Christians worship the Seen God - seen in the person of Jesus Christ. Thus Christians have the liberty of using religious images.
To deny Jesus's death is blasphemy. It's no surprise that many devout Christians completely reject the sinful Jewish repudiation of Jesus.
An entirely futile denial by Jews - since Jews are unable to convert Christians to Judaism (and rarely even try to do so).
Inevitably, since Judaism is a tribal religion, Christianity a universal one.
You take such futility a stage further - since you don't even believe in Judaism !
