Pope Leo XIV
Magnifica Humanitas §68
The Principle of Subsidiarity
Magnifica Humanitas: On Safeguarding the Human Person in the Time of Artificial Intelligence
68 The principle of subsidiarity stems from the very same understanding of the human person that has guided our reflection on dignity and the common good. If every woman and man is called to take ownership of his or her own life and to contribute to the formation of society, then social institutions must also respect and support this responsibility. The Social Doctrine of the Church refers to subsidiarity as the principle according to which the role of individuals, families, local communities and intermediary organizations should not be supplanted by higher-level authorities. Moreover, higher-level institutions must recognize, protect and promote the freedom and creativity of lower-level entities, coordinating their contributions so that they can cooperate effectively for the common good.
