I think I might see part the communication problem. First, I am assuming we are all mystics here. But this language, this nit-picking, this is from accountants and lawyers try to talk theology and metaphysics.
For mystics, nobody is defining God. God is experienced. But afterwards we only have the very limited language of the ambient culture to try to communicate about what we've experienced. And these are always incomplete because they are human artifacts. The Mystery (By whatever name: God, the Ain Soph Aur, The Neoplatonic One, IAO, The Great Spirit, the Universe ) is always far more than what we can say or think about it.
For Plotinus and his successors, the One is absolutely transcendent and unknowable in itself; it's beyond being, beyond thought, beyond language. We can only encounter it through its emanations.
I'm about 50% more animist, but the NeoPlatonism , is a pretty decent operative framework for magic. Here the daimons (angels and demons) in this system function as intermediaries , not as totally independent entities but manifestations that make the incomprehensible One accessible to limited human consciousness. Iamblichus emphasized that our theurgic practices and ritual frameworks matter. They're not arbitrary but shapes how divine reality becomes accessible to us. The gods/daimons meet us through the stories, and symbolic and mythic structures we create.
All our encounters with reality are mediated by interpretive frameworks. The Infinite appearing through culturally-shaped mythology is no less "real" than a scientist's encounter with nature through mathematical frameworks. The forms (whether Yahweh, Krishna, or faerie encounters) are not the ultimate reality itself, but rather, so some or great degree, how the Infinite becomes knowable to our finite consciousness. The map is not the territory, but it participates in the territory.
Simiarly the cultural construction of these experiences doesn't negate their reality, or their source in something beyond the individual psyche. Just as our visual system "constructs" color from wavelengths still reveals something "real" about the world (we assume), our mythic/psychic frameworks construct encounters that genuinely mediate transcendent reality.
On a more practical level, all the angels and demons all have different manifestations depending on the ritual structure I use. If I call Michael using Hebrew rites . to me he comes through he seems far more primordial and, well radioactive. If call him using Folk Catholic novena, he is modulated by the "mythstream" of a very friendly , even cozy religion. It's still him but less outright so much. I do not use Arabic rites, but I imagine he're pretty primoridal there too. again this is prpapyl odulated by how these rites feel to me, as well as the group mind / char toom they exist within.
