Gilbert Murray presents a more down to earth explanation for the Trinity.

For the early Greeks, religion was a cycle of the new god being born of the sky god and the earth mother. To rise up and take the place of the old god. Though by the time of classical Greece, this had become set in stone, as Zeus didn't give way to Dionysus. Tradition had overcome renewal.
So the appeal of the story of Jesus to the Greek world, was it represented a story of renewal, of the new god rising in the spring. The Revolution rises again.
To the Ancients, monotheism equated with monoculture. One people, one rule, one god.
Democracy and republicanism originated in pantheistic cultures. The family as godhead.
So the Romans adopted and co-opted gnostic Christianity as the state religion, as the Empire solidified and remnants of the Republic faded, because it served a useful political function. The Big Guy Rules. Divine right of kings.
Though they couldn't totally erase the Trinity, since it represented the original strength and purpose of Christianity, but since the Catholic Church was to be the eternal institution, the idea of renewal had to be as obscured as possible. As well as neutering the earth mother, to be the holy ghost, because the sexes are to complex to deal with, in a religion whose primary function was social control.
Martin Luther tried to do to the Catholic Church, what Jesus tried with Judaism, push the reset button.
When the West went back to more pluralistic forms of government, it required separation of church and state, culture and civics.
Logically a spiritual absolute would be the essence of sentience, from which we rise, not an ideal of wisdom and judgement, from which we fell. The light shining through the film, rather than the images on it.
Ideals are not absolutes and an entire culture based on the premise has certainly proven to be seriously conflicted.
It doesn't give the resulting feedback loops any circuit breakers, so we have these periodic gran mal seizures.
