From the 1987 encyclical, “On Social Concern”:
“The Church’s social doctrine is not a ‘third way’ between *liberal capitalism *and Marxist collectivism, nor even a possible alternative to other solutions less radically opposed to one another: rather, it constitutes a *category of its own. *”
Sounds like a challenge for the right and the left. The same letter from Pope John Paul II goes on to say:
"Today, more than in the past, the Church’s social doctrine must be open to an international outlook, in line with the Second Vatican Council, the most recent Encyclicals, and particularly in line with the Encyclical which we are commemorating (Populorum Progressio). It will not be superfluous, therefore, to reexamine and further clarify the characteristic themes and guidelines dealt with by the Magisterium in recent years.
Here I would like indicate one of them: the option or love of preference for the poor. This is an option, or a *special form *of primacy, in the exercise of Christian charity, to which the whole tradition of the Church bears witness. It affects the life of each Christian inasmuch as he or she seeks to imitate the life of Christ, but it applies equally to our *social responsibilities *and hence to our manner of living, and to the logical decisions to be made concerning the ownership and use of goods.
Today, furthermore, given the worldwide dimension which the social question has assumed, this love of preference for the poor, and the decisions which it inspires in us, cannot but embrace the immense multitudes of the hungry, the needy, the homeless, those without medical care, and above all, those without hope of a better future. It is impossible not to take into account the existence of these realities. To ignore them would mean becoming like the “rich man” who pretended not to know the beggar Lazarus lying at his gate."
Finally:
“It is necessary to state once more the characteristic principle of Christian social doctrine: the goods of this world are originally meant for all. The right to private property is necessary and valid, but it does not nullify the value of this principle. Private property, in fact, is under a “social mortgage”, which means it has an intrinsically social function, based upon and justified precisely by the principle of the universal destination of goods.”
Does the phrase “social justice” become problematic, then, when a government elected by a majority of the people, who are not all Catholic or Christian, seeks to implement imperfect, but actual (as opposed to theoretical) programs which promote social justice?
