129 "Wherefore," to use the words of Our Predecessor, "if human society is to be healed, only a return to Christian life and institutions will heal it." For this alone can provide effective remedy for that excessive care for passing things that is the origin of all vices; and this alone can draw away men's eyes, fascinated by and wholly fixed on the changing things of the world, and raise them toward Heaven. Who would deny that human society is in most urgent need of this cure now?
