By Robert Royal, The Catholic Thing - In Modern Catholic Social Teaching, these entities are the concrete embodiment of “subsidiarity” – constituents of a properly ordered social structure that limits the reach of the State, a traditional concept that came into renewed prominence in the 1930s with the rise of Communism, Nazism, and Fascism. Each of these ideological movements concentrated social power in a single group: in Communism, the Party; in Nazism, the German Volk; in Fascism, the Fascist State itself. The names change but the DNA of tyranny remains the same.
