With Putin talking about the orthodox church being holy and using to justify some conservative bullshit, all I can remember was the bolsheviks going around the country proudly declaring that cities were now "officially godless" and redistributing the church's gold amongst the people and using it to pay for electrification projects.
My understanding is that Orthodoxy is more of a cultural thing, and that most Russians are still pretty secular. That's what I've heard from Russians anyway.
