Pacem in Terris §141

¹⁴¹ But it is no part of the duty of universal authority to limit the sphere of action of the public authority of individual States, or to arrogate any of their functions to itself. On the contrary, its essential purpose is to create world conditions in which the public authorities of each nation, its citizens and intermediate groups, can carry out their tasks, fullfill their duties and claim their rights with greater security.
