You missed the point and so did I at first. The Ok. license plate in question is not "offered". It's the plate you get for the basic fee. The person who brought suit objected to
the spiritual nature of the license plate that he would be forced to use unless he shelled out more money for a specialty plate. The concept is interesting because the ACLU apparently hasn't noticed a
gigantic breach of the modern concept of "separation of church/state". The theory is that Native American spirituality is less offensive than the 2,000 years of Christian spirituality.
(My bold)
OK, we'll play along. What precisely is the
spiritual nature of the Native People's image on the standard OK license plate? What does this nature say about the driver? Is he reform? Orthodox? Full-immersion, or aspersion? Grape juice or actual wine? Both specie? Either one, alternating? Is there an order of mass or services? Is there a sacred reading @ all? Who officiates @ weddings? A shaman? A witch-doctor? A Voodoo priest?
From the Western point of view, most Native People's religion hardly exists - which was one of the excuses for stealing their land, water, women, cattle & on & on. No government, no capitol building, no legislature, no executive, no judiciary. & now, here in the blessed 21st century CE, the federal courts will seriously entertain the possibility of removing one of the few vestiges of some state-wide respect for Native Peoples' cultures?
Without extensive study & searching on the Internet, I doubt that anyone here can answer even the most basic questions about the image on the license plate & what religious rite he's supposed to be carrying out. Who is he supplicating? What is the name of the rain god? What tradition does that god belong to? What language does He speak? Are there sacrifices involved?
It's amazing that a minister, of all people, wants to pour salt in the wounds of history. Perhaps he has a sponge full of gall to hold up to the warrior's lips? Mayhap he'll pierce the warrior's side, & let the bile run from his side?
& your count of Christianity's reach is considerably off. As it's now Judeo-Christianity, the reach of Christianity is now cumulative - presumably one adds the historical depths of Judaism to Christianity, so the number is likelier 3,000 years. An estimate, I would need to see how far back Judaism extends for a precise figure.
