Pacem in Terris §139

¹³⁹ The common good of individual States is something that cannot be determined without reference to the human person, and the same is true of the common good of all States taken together. Hence the public authority of the world community must likewise have as its special aim the recognition, respect, safeguarding and promotion of the rights of the human person. This can be done by direct action, if need be, or by the creation throughout the world of the sort of conditions in which rulers of individual States can more easily carry out their specific functions.
