Yes, pivotal role----biblical prophecies are not about countries that okayed a pivotal role--they are dealing strictly with world powers. China and Japan and India had their roles too, but are not part of what is being prophesied about. It is the Catholic church that took over in power after the Roman Empire, It did so through religion. There is no comparison between the Orthodox church and the Catholic church as far as power and control over
land and governments and people goes. You're attempts at minimizing it's power are simply because it refutes your attempts at refuting us. It is blinding you to the clear facts.
"Since 313 A.D., when Catholicism became the official religion of the Roman Empire, its power has been in near-constant growth.
The church was able to acquire land, most notably the Papal States surrounding Rome, convert pagan temples and claim relics for itself. Over 300 years, it became one of Europe’s largest landowners.
For the next thousand years, tithes and tributes flowed in from all over Europe. Non-Christians and even fellow Christians were killed and their property confiscated. For example, the Fourth Crusade and the sack of Constantinople in the early 13th century brought it gold, money and jewels."
