It's my impression Moscow never stopped being The Third Rome once they achieved that role in history (circa 1054, by default of the other two losing their cookies, so to speak, especially The First Rome1). Bolsheviks, working for The Vatican and Fascists as well as for themselves, tried to stop Moscow from being that. Non-Zionist Communists backed Bolsheviks off of that objective because they were not as infected, at least not as irretrievably, as Bolsheviks were -- are -- with anti-Christian animus.
Today, baby Bolsheviks join Zionists -- Jewish and nominally Christian (Evangelicals) -- to make another run at Moscow as The Third Rome. Again, it's not Slavs they want to genocide. It's Christians.
Today and for long, Euro-American Fascists fear Slavs for their intelligence and envy them for their wealth. Thus they join with Zionists gladly to subjugate Slavs' center of mass, Russia, to themselves . . . although, Zionists have all those things earmarked for themselves, no one else.
The chief objective of Zionists -- the most influential mal-actors today -- is less to destroy Moscow as The Third Rome than to install Jerusalem as The Third Temple. In their calculations for that project, ownership of Russian wealth would not speed amiss. The U.S. Congress and Foreign Policy Establishment -- and the U.S. MICIMATT -- are fully alive to this . . . how do they call it? . . . opportunity. They are resolved to bring it to pass.
Clear hagiography, even Jews' own deep history as Hebrews, does not countenance this objective. Nor does contemporary, unfolding hagiography, which is visible even through mountains of colossally tragic Sturm und Drang.
Western Bishops, and then The Vatican, unilaterally added the filioque clause to an ecumenical creed — Nicene Creed — that is, they changed an ecumenical statement without ecumenical authority to do that. Shades of recent actions by U.S. Executive Departments and Agencies, the U.S. Congress and the U.S. Judiciary.
