When the things a Pope wrote still made sense
In 1920, Pope Pope Benedict XV wrote Bonum sane:
"The advent of a Universal Republic, which is longed for by all the worst elements of disorder, and confidently expected by them, is an idea which is now ripe for execution. From this republic, based on the principles of absolute equality of men and community of possessions, would be banished all national distinctions, nor in it would the authority of the father over his children, or of the public power over the citizens, or of God over human society, be any longer acknowledged. If these ideas are put into practice, there will inevitably follow a reign of unheard-of terror."
