30 Man cannot be exempted from his divinely-imposed obligations toward civil society, and the representatives of authority have the right to coerce him when he refuses without reason to do his duty. Society, on the other hand, cannot defraud man of his God-granted rights, the most important of which We have indicated above. Nor can society systematically void these rights by making their use impossible. It is therefore according to the dictates of reason that ultimately all material things should be ordained to man as a person, that through his mediation they may find their way to the Creator. In this wise we can apply to man, the human person, the words of the Apostle of the Gentiles, who writes to the Corinthians on the Christian economy of salvation: "All things are yours, and you are Christ's, and Christ is God's." While Communism impoverishes human personality by inverting the terms of the relation of man to society, to what lofty heights is man not elevated by reason and Revelation!
