What Does the Church Say About Nationalism?

Why Everything Depends on Vocabulary

Most disputes about “nationalism” are misunderstandings of words. When a man says “I am a nationalist” to mean that he loves his country and wants to serve it, he is actually describing patriotism. When another denounces “nationalism” while targeting any attachment to a homeland, he is condemning a virtue under a false name. The Church, for her part, has established precise vocabulary, and it is this vocabulary that makes her doctrine intelligible.

Saint John Paul II, who had personally experienced the crushing of his Poland by two totalitarian regimes, gave the clearest formulation of this distinction in his final book, Memory and Identity:

“Patriotism, as love of country, recognizes for all other nations the same right as its own. […] Nationalism, on the other hand, consists in recognizing and pursuing only the good of one’s own nation, without regard for the rights of others.” — Saint John Paul II, Memory and Identity, 2005^[1]

That says it all. The patriot loves his homeland as one loves one’s family: with a preferential love that does not cancel out the justice owed to other families. The nationalist, by contrast, makes the good of his nation the ultimate criterion, before which the rights of other peoples—and, ultimately, even the law of God—are set aside.

Three Distinct Realities

These three notions can be arranged on a scale from fact to disorder.

The nation is therefore not suspect; patriotism is not a concession; and nationalism is not condemned because it loves the homeland too much, but because it loves it wrongly—with a disordered love that overturns the hierarchy of goods.

The False Dilemma: Nationalism or Globalism

Readers are often presented with a binary choice: either nationalism, or a globalism that dissolves peoples into an undifferentiated humanity. The Church rejects both terms of this dilemma. She condemns the idolatry of the nation, but she no more canonizes a rootless cosmopolitanism that would scorn homelands, cultures, and concrete traditions.

Pope Francis has said this in two steps: he observes that “narrow, exasperated, resentful and aggressive nationalisms are reappearing”^[2], but also cautions that “a healthy openness never threatens a healthy love of one’s own land”^[3] and that it is impossible to be truly “local” except from real roots. Between the closed village and the abstract nowhere, Catholic doctrine traces a third way: rooted and open peoples, a preferential love ordered to universal fraternity.

Babel and Pentecost: The Diversity of Peoples in God’s Plan

The Bible does not treat the plurality of nations as an accident to be erased. The story of Babel (Gen 11) shows men who want to build “a city and a tower with its top in the heavens” to make “a name for themselves” and not be “scattered”: the pride of a self-deifying uniformity. God responds by multiplying their languages and scattering them “over the face of all the earth”^[4]. The diversity of peoples is born here as a remedy to unifying pride, not as a curse.

Pentecost (Acts 2) does not abolish this diversity: it reconciles it. When the Spirit descends, each person hears the Apostles “in his own language”—Parthians, Medes, Elamites, inhabitants of Mesopotamia, Judea, Cappadocia^[5]. The unity of the Church is therefore not a uniformity that crushes peoples, but a communion that embraces them. This is the quintessential Catholic model: unity without confusion, diversity without division. Nationalism sins against this unity; leveling globalism sins against this diversity.

“From One Man He Made Every Nation of Men”

The clearest foundation is found in Saint Paul’s discourse at the Areopagus in Athens. Before Greeks proud of their autochthony, the Apostle affirms both the unity of origin of the human race and the providential reality of nations:

“From one man he made every nation of men, that they should inhabit the whole earth; and he determined the times set for them and the exact places where they should live. God did this so that men would seek him.” — Saint Paul, Acts of the Apostles 17:26-27^[6]

Two truths are held together here. On the one hand, all peoples descend from one: there is no superior race, and any claim of one bloodline to dominate another is a fiction. On the other hand, nations, with their “times” and “boundaries”, have a place in God’s plan—they are not accidents to be overcome. The same teaching is already found in Deuteronomy: “When the Most High gave the nations their inheritance, when he separated the sons of Adam, he fixed the boundaries of the peoples.”^[7]

Paul’s conclusion is decisive: nations exist “so that they might seek God.” Their reason for being is not themselves; they are ordered to an end that surpasses them. This is exactly what nationalism forgets when it makes the nation its own end.

The Nation as a Natural Community

The social doctrine of the Church takes up this biblical datum in philosophical form: the nation is a natural community, a real level of social life between the family and the human family. It is neither a mere administrative contract nor a fiction to be deconstructed: it is the concrete fabric—language, memory, customs, landscapes, honored dead—within which a man receives his humanity before he can open himself to the world. To refuse this level of rootedness is to dream of an abstract man who exists nowhere.

But this same doctrine immediately sets the limit: the nation is a penultimate good. Above it stand God, the moral law, and the common good of the whole human family. The nation is a step, not a summit; a means of humanization, not the end of man. “Our citizenship is in heaven,” Saint Paul reminds us (Phil 3:20)—not to despise the earthly city, but to assign it its proper measure.

The Fourth Commandment Extended to the Homeland

Love of country is not, for the Church, an optional sentiment: it is rooted in the fourth commandment, “Honor your father and your mother.” The Catechism explicitly extends this commandment beyond biological parents, to the homeland that has nourished us:

“Love and service of one’s country follow from the duty of gratitude and belong to the order of charity.” — Catechism of the Catholic Church, § 2239^[8]

The reasoning is clear: we have received from our country a language, a culture, protection, a history; justice requires that we repay, in gratitude, the service we can. Patriotism is therefore first of all a recognized debt, a form of expanded filial piety. The Catechism specifies that citizens must “contribute to the good of society in a spirit of truth, justice, solidarity, and freedom”^[9]—which includes cooperation with legitimate authority, defense of the country, and even, if necessary, the duty to serve.

Saint Thomas Aquinas: Pietas Toward the Homeland

The theological tradition had long situated this love. Saint Thomas Aquinas places piety (pietas) toward the homeland immediately after religion. After God, he writes, man is chiefly indebted to those who are the principles of his being and his governance:

“The principles of our being and of our government are our parents and our country, who have given us birth and nourishment. Therefore, after God, man is chiefly indebted to his parents and his country.” — Saint Thomas Aquinas, Summa Theologiae, IIa-IIae, q. 101, a. 1^[10]

The order is crucial. Religion renders to God what is due to Him; piety renders to parents and country what is due to them—but “after God.” Thomistic patriotism is therefore structurally subordinate: it is a virtue precisely because it keeps its place in the hierarchy. The day the homeland demands what belongs to God alone, piety no longer commands us to follow: it commands us to resist.

Leo XIII: Loving Two Homelands, but in the Right Order

Leo XIII formulated this hierarchy with admirable clarity in the encyclical Sapientiae christianae (1890). Far from opposing love of Heaven and love of country, he makes them spring from the same source—God—while establishing their order:

“To love both countries, that of earth here below and that of heaven above, but in such a way that the love of the heavenly country prevails over the love of the earthly country, and that human laws are never placed above the divine law: this is the essential duty of Christians.” — Leo XIII, encyclical Sapientiae christianae, January 10, 1890^[11]

This is the key to the whole doctrine. Love of the earthly homeland is real and obligatory; it becomes culpable only if it claims to surpass the love of God or if the law of the nation is placed above the moral law. Catholic patriotism is therefore not a lukewarm love: it is a hierarchical love.

What Patriotism Commands in Practice

The patriot, according to the Church, is not a man who merely displays flags: he is a man who serves. In concrete terms, love of country requires paying just taxes, respecting just laws, defending the country when attacked, working for its common good, passing on its language and memory, and correcting its injustices rather than covering them up. The Bible itself already asked the exiles in Babylon to “seek the welfare of the city” where they lived and to pray for it (Jer 29:7)—a patriotism extended even to the adopted city. Loving one’s country therefore includes the duty to criticize it when it does wrong: the true patriot wants his country to be good, not just strong.

The Decisive Criterion: The Nation, Under God or Above God?

The shift from patriotism to nationalism is not measured by the intensity of feeling, but by a reversal of hierarchy. As long as the nation remains under God and under the moral law, the love one bears for it is a virtue. As soon as it becomes the absolute to which everything else is sacrificed—truth, justice, other peoples, conscience—this love is corrupted into idolatry. Nationalism, in this precise sense, is a modern form of idol worship: it divinizes a creature.

This is why Pius XI does not reproach nationalism for loving the homeland, but for degrading this love by making it cross the moral boundary:

“Patriotism—an incentive to so many virtues and so many heroic acts when kept within the limits of the law of Christ—becomes a mere ferment of countless injustices when true love of country degenerates into an excessive nationalism; when men forget that all are brothers, members of the same great human family, that other nations have, as we do, the right to live and prosper, and that it is never lawful or wise to dissociate morality from the affairs of life.” — Pius XI, encyclical Ubi arcano Dei consilio, December 23, 1922^[12]

The sentence names exactly the three forgettings that constitute nationalism: forgetting universal brotherhood, forgetting the equal rights of other nations, forgetting that morality is not suspended at the threshold of politics. Wherever these three are forgotten, the nation has become an idol.

Nationalism and the Lie of Race

The most violent form of nationalism is that which relies on the myth of race or blood. Yet Scripture explicitly excludes this: all peoples come from one (Acts 17:26), and in Christ “there is neither Jew nor Greek” (Gal 3:28). In the face of the Nazi deification of race, Pius XII, from his first encyclical Summi Pontificatus (October 20, 1939), condemned totalitarian nationalism and the deification of the State, quoting precisely St. Paul: “there is neither Greek nor Jew” (Col 3:11)^[13]. The brotherhood of origin of the human race is here set, word for word, against racial ideology.

Racial nationalism is therefore not just an overzealous patriotism: it is its negation. The patriot loves a country that includes the resident foreigner, the widow, and the orphan whom the Law already commanded to protect (Lev 19:34, “you shall love the stranger as yourself”). The racial nationalist loves a fiction that excludes. One enlarges the heart to the borders of the country; the other shrinks it to a subset of the country.

The Instrumentalization of Religion

Another boundary is crossed when religion is put at the service of the nation, instead of the nation being ordered to God. This is the central reproach Pius XI addressed to the Action Française of Charles Maurras, condemned on December 29, 1926, with several of his writings placed on the Index in January 1927^[14]. The grievance was not that Maurras loved France, but that, as an agnostic, he used the Church as a political instrument—according to his formula “politics first”—subordinating religion to the nation. By striking a movement that was nevertheless close to part of the clergy, Pius XI affirmed the primacy of the spiritual: faith is not a tool at the service of the homeland; it is the homeland that must allow itself to be judged by faith.

This pitfall has a missionary name. Benedict XV, in the apostolic letter Maximum illud (November 30, 1919), denounced missionary nationalism: the missionary who would work for the prestige of his country of origin rather than for the Kingdom of God.

“It would be a real misfortune if an apostolic man were to spend his strength in extending and exalting the prestige of the homeland he has left behind.” — Benedict XV, apostolic letter Maximum illud, November 30, 1919^[15]

The missionary, the pope reminds us, is “an ambassador of Christ, not a messenger of his own nation.” The Gospel is not a national export product: it is the Good News for all nations.

“My Country, Right or Wrong”: The Nation Against Conscience

The slogan “My country, right or wrong” perfectly sums up the shift. It amounts to saying that national belonging exempts one from judging its actions, that is, to suspending conscience. Chesterton gave the most memorable refutation:

“‘My country, right or wrong’ is a thing that no patriot would ever think of saying except in a desperate case. It is like saying: ‘My mother, drunk or sober.’” — G. K. Chesterton, The Defendant, 1901^[16]

The image is exact: to truly love is not to approve of everything, but to will the good of the beloved—thus ardently desiring that they cease to do evil. The nationalist who covers up his nation’s crimes does not love it more than the patriot who denounces them: he loves it less, for he prefers its prestige to its soul. Conscience, which obliges “even against the law of the land” when that law contradicts the law of God, remains the last bulwark against national idolatry.

It would be mistaken to present the Church’s wariness toward nationalism as a recent novelty, born of a contemporary agenda. It is a constant of the Magisterium for over a century, in the hermeneutic of continuity: each pope, faced with the nationalisms of his time, has repeated the same thing — the nation is a good, but a good that cannot be absolutized without becoming an evil.

Pius XI and Pius XII Against the Idolatry of Race and State

The height of this resistance was reached in the face of the totalitarianisms of the 1930s. The encyclical Mit brennender Sorge (“With Burning Concern”), written in German, dated 14 March 1937 (Passion Sunday) and read from pulpits across Germany on Palm Sunday, 21 March 1937, is the harshest public condemnation ever issued by the Holy See against a contemporary regime. Pius XI unequivocally denounces those who “divinize” race, people, the state, or a particular form of the state: whoever elevates them “above their normal value to an idolatrous level” overturns and distorts the order willed by God^[17]. The wording directly targets National Socialism, but the principle is universal: any absolutization of nation, people, or state is idolatry.

Two years later, barely six weeks after the invasion of Poland, Pius XII took up the fight in Summi Pontificatus. The text condemns totalitarian nationalism, racism, the forgetting of the “law of human solidarity”, and the deification of the state^[18]. Far from silence, it is an anti-manifesto: according to Rabbi David G. Dalin, Allied aircraft are said to have dropped 88,000 copies of the encyclical over Germany^[19], and the Nazi regime, which banned its printing and distribution on Reich territory, read it as an attack^[20]. The thread runs unbroken from Leo XIII to Pius XII: the nation is never God.

Vatican II: A “Magnanimous” Patriotism, But Without Narrowness

The Second Vatican Council did not repudiate this heritage: it balanced it. The pastoral constitution Gaudium et spes explicitly recommends patriotism, provided it remains open:

“Let citizens cultivate with magnanimity and loyalty the love of their country, but without narrow-mindedness, that is, in such a way that at the same time they always take into consideration the good of the whole human family, which brings together races, peoples and nations, united by ties of every kind.” — Second Vatican Council, Pastoral Constitution Gaudium et spes, § 75^[21]

The word “magnanimity” is precious: the Church does not ask for a petty or timid love of country, but a great and generous love — and precisely because it is great, it is open to the good of other peoples. The same council, moreover, lists excessive nationalism among the root causes of wars, alongside injustice and the thirst for power^[22]. To love one’s country in a small-minded way is to prepare for conflict; to love it magnanimously is to serve peace.

Pope Francis Against “Closed” Nationalism

Pope Francis has made the rejection of closed nationalisms one of the central themes of his social encyclical Fratelli tutti (2020). He observes that “narrow, exasperated, resentful and aggressive nationalisms are reappearing”^[23] and warns against those who believe their faith entitles them to support “forms of narrow and violent nationalism, xenophobia and contempt” towards those who are different^[24]. The target is not love of country, but its perversion into hostility.

An Open Rootedness, Not Uprooting

Francis, however, does not fall into the opposite trap of abstract globalism. On the contrary, he defends an assumed rootedness, which is the condition for true openness:

“A healthy openness never threatens a healthy love of one’s own land and people. […] It is not possible to be authentically ‘local’ in a healthy way without being sincerely open to the universal.” — Pope Francis, encyclical Fratelli tutti, § 145-146^[25]

The image he proposes is not the sphere—where all points are equal and indistinguishable—but the polyhedron, where each face retains its own shape while forming a whole. This is the contemporary translation of Pentecost: unity that does not erase peoples, but makes them sing together in their own tongues. Catholic patriotism is this open rootedness: deep enough to keep a person standing, generous enough to despise no one.

Patriotism, Migration, and the Common Good

It is on the issue of migration that the most delicate discernment is required today. The Church professes neither unconditional openness of borders nor selfish closure. The Catechism recognizes that prosperous nations are obliged, “to the extent they are able,” to welcome the foreigner seeking security, but it also recognizes the political authority’s right to make this welcome subject to conditions and to the common good of the host country^[26]. Serving the national common good and the duty of hospitality are not enemies: they are two requirements to be held together, with prudence. Nationalism resolves the tension by sacrificing the foreigner; borderless-ism resolves it by sacrificing the common good; Catholic doctrine refuses to cut the knot and instead calls for governance—which is more demanding.

A Catholic encyclopedia does not refute a straw man. Before concluding, it is necessary to recognize that defenders of the “national” advance real arguments, some of which are valid—and it is precisely this kernel of truth that makes nationalism attractive.

“Love Your Own First”: The Order of Charity

The first argument is solid: charity itself is ordered. One cannot love “humanity” in general without first loving concrete neighbors—family, neighbor, fellow citizen. This ordo caritatis is taught by Saint Thomas and reflected in pietas toward the homeland. The argument is correct against an abstract humanitarianism that would claim to love those far away while despising those nearby.

However, it goes astray as soon as “first” is turned into “only.” To love one’s own first does not mean to love only them, nor to sacrifice to them the justice owed to others. The order of charity ranks loves; it does not exclude them. Patriotism says “first”; nationalism hears “exclusively”—and that is where it departs from charity.

“Without Rooted Peoples, Man Becomes Dehumanized”

The second argument is just as serious: a person without a homeland, without a received language, without shared memory, is an impoverished person, delivered over to the market and to abstraction. Concrete cultures are treasures of humanity, and a political project that would flatten them in the name of undifferentiated humanity would be inhuman. On this point, the “national” aligns with Catholic doctrine: this is exactly what Francis defends when he condemns the “false openness to the universal” of the uprooted^[27].

The argument goes astray when rootedness turns into closure and contempt: when culture becomes a weapon against other cultures, when memory becomes resentment, when defending one’s own becomes hatred of others. The writer Romain Gary’s formula—in European Education (1945), through the voice of the partisan Dobranski—sets the boundary well: “Patriotism is love of one’s own. Nationalism is hatred of others.”^[28] The dividing line is not between those who love their country and those who do not; it is between love that enlarges the heart and passion that closes it.

Where the Argument Is Right—and Where It Goes Astray

The discernment can be summarized in three steps. The “national” is right to affirm that the nation is a good, that rootedness is necessary, and that love of those close precedes love of those far away. It is wrong as soon as it makes the nation an absolute, subordinates morality to national interest, or turns legitimate preference into exclusion of other peoples. And it is attractive because, in a world of abstractions and uprootedness, it offers a warm and concrete belonging—a real need to which the Church responds, not with globalism, but with the ordered patriotism she has always taught.

At the end of this journey, the answer to the question “What does the Church say about nationalism?” can be summed up in a few clear certainties.

• The Church does not condemn the nation: she blesses it as a good willed by God. From Athens (Acts 17:26) to Pentecost (Acts 2), the diversity of peoples belongs to the divine plan, and the nation is a natural community, between the family and the human family.
• Patriotism is a virtue, not a concession. It stems from the fourth commandment and the order of charity (CCC § 2239), from Thomistic piety toward the homeland, and is explicitly recommended by Vatican II—provided it is “magnanimous” and “without narrowness.”
• Nationalism is condemned when it becomes idolatry. The criterion is not the intensity of love, but the hierarchy: does the nation remain under God and the moral law, or does it overturn them? To love one’s country is right; to divinize it is a fault.
• This condemnation is constant and continuous. From Leo XIII to Francis, including Benedict XV, Pius XI, and Pius XII, the Magisterium has repeated the same teaching against the nationalisms of every era: missionary, excessive, racial, totalitarian, aggressive.
• The Church rejects the false choice between nationalism and globalism. Against the national idol as well as the uprooted “nowhere,” she proposes peoples who are both rooted and open—the polyhedron of Francis, heir to Pentecost.

Catholic patriotism is therefore neither a flag brandished against others, nor a shameful feeling to be hidden. It is an ordered love: deep enough to root a person in a real homeland, humble enough to know it is not ultimate, broad enough to recognize for every other people the right it claims for its own. The nation is not God—and it is precisely because it is not God that one can love it without betraying it.

• What does the Church say about just war? — the critique of collective passions, including excessive nationalism, which fuel unjust wars.
• What does the Church say about politics? — the broader framework of the common good, legitimate authority, and the primacy of the spiritual.
• What does the Church say about immigration? — the articulation between the duty of hospitality and the common good of the host country.
• What is the natural law? — the rational foundation that places the moral law above any national law.
• What is moral conscience? — the last bulwark against the “my country, right or wrong” mentality.
• What is the Mystical Body of Christ? — the unity of the baptized beyond borders and flags.
