Good social relations, the common good, and three matters of the utmost urgency, according to Leo XIV
Pope Leo XIV delivered his general audience on September 16, 2026, in St. Peter’s Square, after a brief delay caused by a preceding private audience. He devoted his catechesis to the Constitution “Gaudium et Spes”, stressing its relevance for the human community and the Church’s mission. The Pope identified three matters of utmost urgency, linking them to principles of good social relations and the common good. He reaffirmed the Church’s commitment to social justice and solidarity in the contemporary world. The address underscored the continuity of Leo XIV’s theological focus on the human dimension of the Church’s mission.

Pope Leo XIV used his September 16 general audience to continue his catechesis on Gaudium et Spes, focusing on human community, the common good, and the responsibilities created by humanity’s growing interdependence. He connected the Second Vatican Council’s teaching to digital technology, artificial intelligence, social justice, respect for human dignity, and participation in public life.
Leo XIV said technological development, mass media, social media, and artificial intelligence can overcome barriers and reduce distances. At the same time, he warned that relationships risk becoming increasingly virtual and less personal, with people potentially delegating to algorithms decisions that belong to human conscience.
He presented the Christian community’s contribution as helping ensure that social relationships retain “real substance and personal depth.” Drawing on Gaudium et Spes, he said humanity’s interdependence must be fulfilled through communion between persons and mutual respect for every individual’s spiritual dignity.
The Pope emphasized that personal development and the development of society are inseparable. Social institutions, he said, must have the human person as both their subject and goal, since people need social life by their very nature.
He also described human and cultural diversity as a source of enrichment rather than a threat. In his presentation, conflict and violence arise from sin and destructive patterns of thought and action, while reciprocity, sharing, and care offer an alternative grounded in human solidarity.
Leo XIV defined the common good, following Gaudium et Spes, as the totality of social conditions that allow individuals and groups to pursue their fulfillment. He added that every social group must consider the needs of other groups and the welfare of the entire human family.
The first consequence identified in the catechesis was respect for the human person. Leo XIV cited Gaudium et Spes in condemning attacks on life, including murder, genocide, abortion, euthanasia, and intentional self-destruction.
He also included violations of bodily and mental integrity, coercion, degrading living conditions, arbitrary imprisonment, deportation, slavery, prostitution, trafficking in women and children, and exploitative working conditions among the offenses against human dignity.
The second consequence was respect and love for adversaries and for people whose beliefs or conduct differ from one’s own. The teaching calls for relationships that do not treat disagreement as a justification for hostility or exclusion.
The third consequence was the fundamental equality of all human beings and the resulting obligation to pursue social justice. Leo XIV reiterated the Council’s rejection of discrimination based on sex, race, color, social condition, language, or religion.
The catechesis concluded with a call to overcome individualism and adopt greater responsibility and participation in social life. Leo XIV said the Council’s vision of humanity as a “community of people” can help individuals and communities assess political and social projects according to human dignity, social justice, and free participation.
He ended by stressing that humanity’s future depends on each person’s cooperation with God and with others in building a more humane world.
Examine how “Gaudium et Spes” informs contemporary Catholic social teaching
Gaudium et Spes remains foundational for contemporary Catholic social teaching—not because it supplies ready-made policies for every issue, but because it establishes a method: read the “signs of the times,” interpret them through the Gospel, and judge social structures by whether they serve the integral dignity and vocation of the human person.
The constitution rejects both withdrawal from society and uncritical acceptance of modernity. The Church is called to discern “the happenings, needs and desires” of each age, recognizing what reflects God’s purposes while purifying values distorted by sin.
This provides the basic approach of contemporary Catholic social teaching. Social questions are not treated as merely technical or political matters. They are examined through theology, moral philosophy, social analysis, and practical wisdom. Pope Leo XIV describes this as a process of interpreting historical change through the Gospel together with human expertise. Dialogue with the world is therefore part of the Church’s mission, not simply a public-relations strategy.
The central criterion is the dignity of every human person. Gaudium et Spes teaches that social arrangements must serve persons rather than subordinate persons to institutions, markets, ideologies, or the state. The common good consists of the social conditions that enable individuals and communities to pursue genuine fulfillment.
This principle informs contemporary Catholic concerns about:
The Council connects dignity with concrete rights, including food, shelter, education, employment, family life, a good reputation, truthful information, privacy, and religious freedom. These rights are not presented as isolated individual claims: they belong within a moral order oriented toward justice, truth, freedom, and love.
Gaudium et Spes anticipated the increasingly global character of social life. As human interdependence grows, the common good acquires a universal dimension: groups and nations must consider not only their own interests but also the welfare of the whole human family.
This insight underlies contemporary Catholic teaching on globalization, international development, war and peace, refugees, climate and ecological responsibility, and global economic structures. It also explains why Catholic social teaching criticizes both isolationism and forms of globalization that benefit the powerful while leaving poorer nations dependent. The Council already observed that developing nations could remain economically subordinate even while being invited to participate in modern civilization.
Thus, solidarity is not merely private generosity. It is a responsibility to shape institutions so that the benefits and burdens of social life are distributed justly.
The Council’s teaching also supports a participatory understanding of social life. Workers, farmers, women, nations, and marginalized groups seek not only material benefits but a genuine role in shaping economic, political, social, and cultural life.
This contributes to contemporary emphasis on:
At the same time, Gaudium et Spes does not equate freedom with liberation from every moral truth. It affirms conscience and human liberty while warning against a “false autonomy” that treats the person as answerable to no objective moral order. Human rights are therefore affirmed, but they are understood within human nature, responsibility, truth, and the person’s ultimate relationship with God.
The Council offers a qualified confidence in human progress. Human achievements can manifest God’s greatness and contribute to a better ordering of society, but technological and cultural development is morally ambiguous. It can serve human flourishing or become a means of domination.
That framework is especially relevant to artificial intelligence and emerging technologies. The question is not simply whether an innovation is efficient or profitable, but whether it respects human agency, truth, work, privacy, justice, and the common good. Pope Leo XIV explicitly applies this tradition to the age of artificial intelligence, calling for renewed reflection on the common good, solidarity, subsidiarity, social justice, and the universal destination of goods.
In this respect, Gaudium et Spes supplies a way to evaluate technology without either technophobia or technological utopianism.
Although Gaudium et Spes addresses public and social realities, its account of dignity is ultimately theological. The human person is understood in light of Christ, who assumed human nature and sanctified the whole person—body and soul—through the Incarnation, Cross, and Resurrection.
Consequently, Catholic social teaching is not reducible to a political program or a humanitarian ethic. It seeks social justice because every person is created by God, redeemed by Christ, and called to communion with God. Social reform and evangelization are distinct, but they cannot be separated: the Gospel both reveals human dignity and demands that social structures respect it.
Contemporary Catholic social teaching develops the principles of Gaudium et Spes in response to new circumstances. Its enduring principles remain stable, while their concrete application changes as societies, technologies, economies, and political conditions change. Pope Leo XIV describes this as a “harmonious, though not always linear” development in which later teaching deepens earlier insights without abandoning their foundations.
The result is neither an unchanging catalogue of policies nor unrestricted adaptation to cultural fashion. It is a continuing discernment governed by human dignity, the common good, solidarity, subsidiarity, justice, peace, and the universal destination of goods.
In summary, Gaudium et Spes informs contemporary Catholic social teaching in three decisive ways: it places the human person at the center, makes the Church attentive to historical realities, and insists that social progress be judged by the Gospel. Its enduring question is whether economic, political, cultural, and technological developments genuinely serve the integral flourishing of every person and the whole human family.
