Bolsheviks were able to fulfill the social idea in Russian reality only in ideological and economic sphere. The main barrier they had to over come was the transformation of living in Russian Empire people. Naturally, that the real picture of Russian reality in this direction by communists should be well known and studied. This important and complicated question was planned by Bolshevik party: among the theorists of social society construction (Lenin-Trotski plan: workers, farmers, intellectuals, army) was no place for the Church. The Church, serving Tsarism and Provisional Government, for Bolsheviks was out of use. All above mentioned was just a motive of unimical treatment of the Church in post-revolution Russia.
