Populorum Progressio §78

⁷⁸ Such international collaboration among the nations of the world certainly calls for institutions that will promote, coordinate and direct it, until a new juridical order is firmly established and fully ratified. We give willing and wholehearted support to those public organizations that have already joined in promoting the development of nations, and We ardently hope that they will enjoy ever growing authority. As We told the United Nations General Assembly in New York: "Your vocation is to bring not just some peoples but all peoples together as brothers. . . Who can fail to see the need and importance of thus gradually coming to the establishment of a world authority capable of taking effective action on the juridical and political planes?" (66)
