Great post!
You are right about everything in your remarks...
But going back to the Dyonysian experience which inspire Nietszche and his sacred festivities but especially going back to the Mysteries Sacred schools experiment like in Eleusis, which was a center of sprit around for all people of the mediterranean sea, we realized the experience of spirit in Greece is not completely foreing to the ancient hebrew "ruach" perception and experience....
The intimate participation to the spirit mimic one another in Greek and Jews and in all cultures anyway , the spirit experience ultimately is the same, think about NEAR DEATH EXPERIENCE for example or out of the body experiences, but the way to express it and partipate to nature differ...
One of the best book on that is Peter Kingsley "reality"....Jews civilization of the Alexandrine period and after it is way more nearer to the Greek that what we had learned in our younger days...
Alexandria was the cosmopolitan Paris/ Newyork of the ancient world and jews scholars meets there with Greeks even were influenced by Greek thought on a level underestimated completely 50 years ago..

Just a meaningful anecdote: Egyptian priesthood at the bibliotheca of Alexandria, the biggest in the world collected all documents of ANY political constitution or about philosophy and science they coud grap... They ask Corinthians for example give us your city constituion written document, we will copy it and return you back, in the mean time we will send you a gold warrenty for sure... Corinthians obeyed and accepted the gold send their constitution; but after some years, the Egyptians never answering the Corenthians demands for the retrurn, said keep the gold we keep the constitution and we will send you a copy.... That speak a lot about their passionate urge to collect EVERYTHING ....They ask jews scholars what are your people think about God, your history , etc wrote it for us and we will keep it in the bibliotheca... Guess what comes from it? It is Gmirkin well researched thesis...
Humans of all culture are way more similar to one another that they ever think they are, but they dont understand it, they dont want to know it, and they do all they can to prove this wrong...The experience of the spirit is the SAME all over the world, but the way we participate to nature is not....
Humans are connected by the heart and separated by the body....
We must speak sometimes to one another from a wider perspective like the OP wisely suggest...
But you are right also for sure in some way about this perilous tentative...
Second, in a forum such as this, it’s a real challenge to adequately express complex philosophical, ethical, religious (spirit-ual) concepts, considering the nature of the medium and its audience. In retrospect, maybe doing so is a fool’s errand.
