The demands of the common good concern above all the commitment to peace, the organization of the State's powers, a sound juridical system, the protection of the environment, and the provision of essential services to all, some of which are at the same time human rights: food, housing, work, education and access to culture, transportation, basic health care, the freedom of communication and expression, and the protection of religious freedom.
Nor must one forget the contribution that every nation is required in duty to make towards a true worldwide cooperation for the common good of the whole of humanity and for future generations also.
