Magnifica Humanitas §59

⁵⁹ Recognizing that every man and woman possesses an inalienable dignity, together with rights that no human power can betray or nullify, requires us to shape the way we live together, including our economic and political choices, and the makeup of our cities. From this arises the first major principle of Social Doctrine that I wish to highlight: the common good. We can describe it as the social expression of the dignity recognized in every person. When Benedict XVI referred to the non-negotiable values that the Church must always defend, he included among them “the promotion of the common good.” For a Christian, going beyond the narrow confines of one’s own interests and committing oneself, within the limits of one’s ability, to the common good is a non-negotiable value, as is the promotion of life.
