Magnifica Humanitas §73

⁷³ Having considered the common good and subsidiarity, I would like to reflect on the principle of solidarity. This emerges from a vision of the human person generated by faith, namely that every human being is created in the image of God and is part of a network of relationships that bind him or her to others, to specific populations and to creation. Saint Paul VI observed that the obligations of solidarity, justice and charity are rooted in the human and supernatural fraternal bonds that unite individuals and populations. Fraternity is not merely an aspiration of believers, but is a social and political reality to be embodied in communal choices and endeavors. Solidarity, then, is the concrete recognition that the future of each individual is connected to the future of all; indeed, “no one is saved alone.” The close link between subsidiarity and solidarity thereby becomes evident. When subsidiarity is not linked to solidarity, it ends up becoming merely the protection of particular interests; when solidarity is not supported by subsidiarity, it degenerates into a form of welfare that does not foster responsibility. This interconnectedness also pertains to the responsibility of authentic participation. Solidarity is expressed when each person, both individually and collectively, takes part in the life of the community — by staying informed, engaging with others, making their voice heard and contributing to public decisions and choices — while also assuming real responsibility so that the common good is achieved through shared decision-making.
