"I am confused by this idea that Orthodoxy owes a debt of gratitude to Moscow. What exactly do you mean?"
Who ignored the Council of Florence while a compromised EP was still preaching it? Moscow.
Who came to the aid of Orthodox Christians when Muslims and Catholics alike were out to remove them from the Holy Land in things like the Crimean war? Moscow.
Who freed the Ukrainian and Belarussian churches from Catholics who'd confiscated every church and murdered everyone who disagreed? Kossaks with major support from Moscow.
It's been 800+ years since a strong Constaninople was preventing Heretics and Schismatics from murdering Orthodox Christians and stealing their church or raising them to the ground.
Who exactly do you feel has been stepping up in the mean time?
Ecatly, yet the attitude is "the MP should behave..." to echo +Leo's words about the EP.
