The Greekification and Russification of history is disgusting! Cyril and Methodius were Bulgarian; there's plenty of evidence about it, and they created the Glagolic alphabet, while the Cyrillic alphabet is 100% Bulgarian-made without any doubt. Not to mention that Old Bulgarian was the official language in Russia for a while - all this confirmed by honest Russian scholars. But, hey, can the Soviets allow a small country like Bulgaria to be so important for its culture, right? But it's disgusting how "Orthodox" nations are being so nationalistic, love to erase, and rewrite history. That's not Orthodoxy!
Do you know that the first concentration camp in Europe was actually in Greece [0], and Bulgarian priests were put in it and died? So Orthodox, right?
