I tend to agree with you. Ialso tend to think of Trinity as a modulation of the Mystery (the Numinous, God. the One, the Tao, the whatever ) into more human-space by human needs, wishes, and prayers.
This is a concept that precedes him but Frater Acher he has done a great job here visualizing this:
"Think of a giant water damn wall. Behind this wall resides a massive amount of power in potential. Over millennials of evolution smart humans managed to build valves into this massive wall, which now allow us to open and close these individually. Thus humans learned to leverage the water pressure behind the wall through specific power access points which in return have become controllable and can be harnessed to accomplish all kinds of man-made plans. Depending on which valve is opened and for how long we get a certain kind of pressure and quality of water. And with that we can work in whatever kind it pleases us."
I was not raised particularly religious, by engage with the Catholic magical systems just fine. I feel it's important to consider that it's not required for your intellect to 100% taken over by all this. It will work even if you don't totally mind-fuck yourself into accepting as these "impossible and dumb" things. Ultimately they are mysteries, not dry "facts." This approach keeps our kerplunky accountant's brain - the left hemisphere - from meddling too much, if we consider these sacred ideas and off limits to its grubby survival-focused little rodent fingers.
Monotheism and the recognition of a supreme overarching divine principle also long predate Abrahamic tribal frameworks. Solomonic grimoire magic is fundamentally an extension of Catholic sacramental technology.
And Catholicism is actually Hellenic, not Abrahamic, and was built upon a Paleolithic-to-Neolithic trajectory across Eurasia that points toward a deep-seated recognition of a High God - often an distant overarching sky father or cosmic order (what Wilhelm Schmidt called
Urmonotheismus), surrounded by a court of lesser spirits, ancestors, and localized
numina. (a word originating from ancient Roman religion, a
numen was not a fully fleshed-out human-like god with an elaborate mythology and backstory. These sit on the Catholic God's Divine Council, accompanied by divinitized humans, principalities, powers, archangels, etc. Now all this metaphor (and mythic poetry) but I also feel it's the closest description of what going on, in my personal opinion.
Paul using the stories of "YHVH" as a proxy stand-in for the Ancient Nameless God. He never made a reference to a human Jesus, whjo was always a vision of a cosmic god. This is historically and philosophically precise. When his Hellenized mind encountered the localized storm/warrior deity of the ancient Levant, he an others immediately translated that figure upward into the Platonic Theon - the Prime Mover, the Good, the Monad. Paul’s God in the Areopagus speech is explicitly
agnostos theo - the Unknown God. Paul was culturally a Hellene.
The best book at this time for more on this is

Oh. The DNA of the Grimorium Verum (my man grim) has been traced back to 14th-century Italy, placing it at the center of late medieval scholasticism, clerics, scribes, and minor church orders were knee-deep in ritual innovation and medical astrology.
Grimoire magic is built on a universal cosmic hierarchy, and the top end is vastly more universal than a narrow tribal formulation, and anyone operating within that mythic framework can plug into it. It is quite alive, I have found, and you might find yourself learning far more about the fine points of Catholic and Neoplatonic history than you would ever expect otherwise. If that does not interest you, try the PGM as a ritual framework.
