The Church “is not entitled to express preferences for this or that…solution. Her contribution to the political order is precisely her vision of the dignity of the person revealed in all its fullness in the mystery of the Incarnate Word.”
Catholic social teaching is built on three foundational principles - Human Dignity, Solidarity and Subsidiarity. Human Dignity, embodied in a correct understanding of the human person, is the greatest. The others flow from it. Good governments and good economic systems find ways of fostering the three principles.
This means a correct understanding of the human person and of each person’s unique value. All Catholic social teaching flows from this: the inherent dignity of every person that comes from being made in God’s image.
Solidarity is not “a feeling of vague compassion or shallow distress at the misfortunes of others. It is a firm and persevering determination to commit oneself to the common good”. (Pope St. John Paul II, 38) Love of God and love of neighbor are, in fact, linked and form one, single commandment.
Subsidiarity “is a fundamental principle of social philosophy, fixed and unchangeable, that one should not withdraw from individuals and commit to the community what they can accomplish by their own enterprise and industry. So, too, it is an injustice and at the same time a grave evil and a disturbance of right order to transfer to the larger and higher collectivity functions which can be performed and provided for by the lesser and subordinate bodies”. (Pope Pius XI)
