The other part that is often missed is that this is largely Orthodox Christian in origin.
Protestanism has failed. Catholicism is failing before our very eyes. Both are considered heresies from the Ortho perspective, and this 1000-year argument is now at the "I told you so" stage.
Orthodoxy is based in Byzantium Empire, & since it's fall, has thrived on a decentralized model of church nationalism - Greek, Russian, Syriac etc.. that shares power with the state.
Not a theocracy.
