Catholic Social Teaching: Solidarity
TL;DR: Solidarity=working for common good based on common humanity.
As we dive into 2026, we continue our series on Catholic Social Teaching by explaining another foundational principle called solidarity. Unlike subsidiarity, most people think they have a definition of solidarity: a sense of compassion or feeling bad for someone struggling. Yet we’ll discover that the Church’s vision for solidarity goes far beyond the realm of feelings to the realm of action.
Solidarity is a moral virtue, meaning it’s a good action done repeatedly and developed as a habit. What is the good action? As St. John Paul II explains, “it is a firm and persevering determination to commit oneself to the common good” (Sollicitudo Rei Socialis 38). The principle of solidarity is grounded in our belief that each person (regardless of differences) is a member of the human race, made in the image and likeness of the same God. As fundamentally social creatures, we depend on one another for countless things. If you recall, the common good are the preconditions in society that help people thrive: access to basic necessities of life (food, housing, healthcare, education, transportation, communication), a sound juridical and political order, peace and security, and environmental stewardship.
What gets in the way of the common good? The Church defines these obstacles as ‘structures of sins’. They are not reducible to an individual’s personal sins but act like a societal poison. The cycle of extreme poverty traps everyone except the extremely tenacious or the extremely lucky. Systems of injustice repeatedly belittle victims and ‘stack the deck’ against them. For many red-blooded Americans who have an entrepreneurial spirit, this theory of systemic sin seems wrong. Just work hard, pay your dues, and eventually you’ll achieve success, right? One thing is clear: Jesus Christ did not share this perspective on suffering. By becoming human, Christ united himself with all of humanity, especially those who suffer. He neither blamed the blind man (try harder) or his parents (raise him better) for his infirmity (Jn. 9:3). He constantly broke down obstacles to social integration through his healings. The disabled lived among the able, the sick among the healthy, the outcasts among the mainstream because of him. Jesus calls all his followers in every age to see his face in the “least of my brethren” (Mt. 25:31-46). Putting solidarity into practice means working habitually to improve the lives of others by pursuing the common good in Jesus’ name.
So how can we live out solidarity in practical ways? Material support, advocacy, and friendship. Supporting our new twinning partnership with St. Michael Charanga in Kenya was an excellent demonstration that Catholics in Kenya are part of our family and need access to key resources to thrive. Donating to the Bakhita House back in the spring achieved a similar goal. Beyond donations, advocating for the marginalized and the unloved is a powerful form of solidarity through ministries like Thrive For Life (convict rehabilitation) or Voices for Justice (legislative advocacy for children, families, and the poor). Finally, befriending the marginalized in whatever form (the working poor, the disabled, cultural or racial minorities) tangibly demonstrates the love of Christ in solidarity. We are one human race, and Christ’s solidarity with us must overflow into our determined pursuit of the common good for others.
