Rerum Novarum: A Manifesto for the Ages

When Pope Leo XIII issued Rerum Novarum in May 1891, he was not drafting a pious ornament to nineteenth-century economic debate. He was making a decisive intervention in the struggle between two destructive forces that were devouring the social order of Europe: the growing menace of socialism on the one hand, and on the other, the suffocating dominance of corporate and landed oligarchies whose power rested not on the competitive virtues of a free market but on privileges granted and enforced by the State.

Many modern Catholics have absorbed the idea that the encyclical is a simple defence of capitalism in its modern, corporate form. But to read it attentivelyโ€”especially in light of the theological tradition of Augustine and Aquinas on which it restsโ€”is to see that Rerum Novarum is in fact a sustained rejection of the two-headed monster of collectivist statism and state-privileged monopoly capitalism. It defends private property, but not privilege; it upholds the dignity of labour, but not the power of those who treat labourers as disposable instruments; and it insists on a State limited by natural law, a guardian but not a master, an umpire but not a proprietor.

The encyclicalโ€™s starting point is the declaration that the human person precedes the State, both in the order of creation and in the order of justice: homo republica antiquior est (โ€œman is older than the State,โ€ para. 13). This is not a rhetorical flourish but an anthropological and theological statement. Man, made in the image of God, has a dignity that no political order can either confer or remove. Augustine, in De Civitate Dei (XIX, 15), reminds us that human society begins in the natural bonds of family and neighbourliness, long before kings and magistrates: political authority is a post-lapsarian necessity, not a primordial constituent of human identity. Aquinas takes this further in the Summa Theologiae (I-II, q. 95, a. 2), insisting that human law derives its legitimacy from its conformity to natural law. A law that contradicts the moral order is, in Aquinasโ€™s phrase, magis est iniquitas quam lex (โ€œis more an injustice than a lawโ€), and to the extent that it is enforced, it does not bind in conscience. When Leo XIII insists that man is older than the State, he is re-asserting this tradition: the rights to life, property, association, and the fruits of oneโ€™s labour are not State-created concessions but God-given endowments, and the Stateโ€™s role is to protect them, not to regulate them out of existence or grant them selectively to its favourites.

It is in this context that the Popeโ€™s defence of private property must be understood. He writes in paragraph 9: Itaque qui operam suam locat, id facit ut necessaria ad victum acquirat (โ€œWhen the worker places his energy and his labour at the disposal of another, he does so for the purpose of getting the means necessary for livelihoodโ€). Here Leo is making two related points: first, that labour is directed to the sustenance of life, and second, that the natural outcome of labour is the acquisition of property. This is wholly consonant with Aquinasโ€™s teaching in the Summa (II-II, q. 66, a. 2), where he argues that while the use of goods should be commonโ€”meaning oriented toward the good of allโ€”the ownership of goods should be private, because individuals can manage their own property more efficiently and responsibly than a collective can. But the same Aquinas also insists that to seize anotherโ€™s goods by unjust law, or to keep them when they are needed by the poor, is a form of theft. If property is justified as the means by which a man fulfils his duty to provide for himself and his family, then it is perverted when it becomes a lever for reducing others to dependency.

Here lies the reason why Catholic teaching is, in principle, hostile to the vast enterprises that depend upon State privilege for their existence. A corporation that grows large by honest service, on equal terms with its competitors, is one thing. But a corporation whose market share is preserved by protective tariffs, by regulatory barriers designed to crush small rivals, by direct subsidies, or by the artificial shield of limited liability against just claims, is a creature of law in the pejorative sense: an instrument of privilegium, not a participant in free exchange. Such entities embody what Augustine condemns in De Civitate Dei (IV, 4) when he likens kingdoms without justice to โ€œgreat robberiesโ€ (magna latrocinia). They convert the State from a guardian into an accomplice, using its coercive power to do what they could not accomplish in honest competition.

Leo XIII knew this pattern well, even if the modern jargon of โ€œcorporate welfareโ€ did not exist in his day. The industrial capitalism of the late nineteenth century was thick with railway monopolies granted land and rights-of-way by governments, with banking cartels sustained by legal tender laws and charter restrictions, with manufacturers shielded from foreign competition by protective duties that raised prices for all. Against such an order, the Pope sets not socialism, which he rightly saw as a project for absorbing all property into the State, but a decentralised economy of self-supporting households, independent tradesmen, and voluntary associations. He praises the โ€œcollegia artificumโ€ (guilds of craftsmen, para. 69) as examples of how workers, free to organise themselves without State interference, can secure mutual aid, training, and standards of work. Ius naturae est ut homo societates privatas constituat (โ€œIt is a right of nature for man to form private societies,โ€ para. 72), and to suppress or absorb such societies is to do violence to the natural order.

Aquinas, in Summa Theologiae (I-II, q. 95, a. 4), affirms that human beings, being social animals, naturally form associations to achieve common purposes. Augustine, in De Civitate Dei (XIX, 13), defines a people as โ€œan assemblage of reasonable beings bound together by a common agreement as to the objects of their love.โ€ In both cases, the implication is that the health of a society depends on the freedom of these intermediate bodiesโ€”families, guilds, cooperatives, parishesโ€”to pursue their own ends. When the State, acting in concert with privileged corporate powers, destroys or absorbs them, it hollows out the social order, leaving only the isolated individual and the monopolistic power bloc. In such conditions, โ€œeconomic freedomโ€ becomes a hollow phrase, for the individualโ€™s only โ€œchoiceโ€ is between servitude to a handful of State-sheltered employers or destitution.

The dignity of labour, as Rerum Novarum insists in paragraph 31, is not to be found in the wage slip alone: Opusโ€ฆ non est homini dedecus, sed honor (โ€œGainful occupations are not a mark of shame to man, but rather of respectโ€). This dignity is most fully realised when the worker is free to direct his labour toward his own ends, whether by self-employment, by cooperative association, or by work for another under conditions that respect his humanity. Aquinas (II-II, q. 187, a. 3) sees labour as a participation in Godโ€™s own creative activity; Augustine warns against the vice of treating oneโ€™s fellow as a mere instrument for oneโ€™s own gain. In the world of the State-privileged monopoly, this warning is ignored: men become โ€œhuman resources,โ€ to be shuffled, cut, or outsourced in pursuit of quarterly targets, with the law standing ready to protect the prerogatives of the few who command such enterprises.

It is here that Leoโ€™s teaching on the just wage becomes central. In paragraph 63, he declares: Est igitur iuris naturalisโ€ฆ ut merces non sit minor quam quae frugi et recte morato operario vitam sustentet (โ€œThere is a dictate of natural justiceโ€ฆ that the wage shall not be less than enough to support a worker who is thrifty and uprightโ€). The point is not that the State should fix wages by decree, but that justice itself demands a level of remuneration sufficient to allow the worker to maintain his household in dignity and, ideally, to accumulate savings. These savings are the seed of independence: they make it possible for a labourer to acquire a plot of land, to start a small shop, to enter a partnership. In a society dominated by privileged giants, this upward path is deliberately obstructed. The privileged few prefer a permanent class of dependent wage-earners, easily disciplined by the threat of dismissal and with no realistic alternative to submitting.

Taxation, too, is treated by Leo with suspicion when it becomes an instrument of expropriation rather than a contribution to the common good. In paragraph 67, he warns against onera publica nimis gravia (โ€œcrushing taxes of every kindโ€), which sap private wealth and discourage the virtues of thrift and enterprise. Aquinas (I-II, q. 96, a. 4) condemns laws that impose burdensome obligations without necessity, and Augustine sees in excessive taxation the hallmark of rulers who govern for their own enrichment rather than for justice. In the modern mixed economy, where taxes raised from the many are channelled into subsidies and guaranteed contracts for the few, the injustice is doubled: the taxpayer is not only deprived of his own resources, but made to finance the system that keeps him subordinate.

Underlying all these particular teachings is a theological anthropology that refuses to reduce man to an economic unit. Augustineโ€™s diagnosis of the libido dominandiโ€”the lust to dominateโ€”applies as much to economic as to political life. The great temptation of those who hold wealth and power is to view their fellow men as means rather than ends, as inputs to be optimised. Aquinas, in his treatment of commutative justice (II-II, q. 77), is explicit that to take advantage of anotherโ€™s necessity to extract more than a fair return is a sin against the natural law. This is why Catholic social teaching, from Leo XIII onwards, consistently refuses to sanctify the corporate behemoth simply because it is โ€œprivateโ€ rather than โ€œpublic.โ€ Size and power, when sustained by privilege, become instruments of oppression, no less than the bureaucratic ministries of the socialist state.

If we read Rerum Novarum without the distorting lens of Cold War polemic, what emerges is a vision of economic life that is neither laissez-faire in the modern corporate sense nor statist in the socialist sense. It is an order of widely distributed property, of many centres of initiative, of a State that protects but does not command, and of associations that mediate between the individual and the State. It is an order in which the chief enemies of liberty are not only the collectivist ideologue but also the billionaire whose fortunes depend on grants, both direct and indirect, of privilege by the State. It is precisely because Catholic teaching sees human beings as bearers of inalienable dignity that it resists any systemโ€”whether draped in the red flag of socialism or the balance sheets of a privileged monopolyโ€”that treats them as mere โ€œresourcesโ€ to be allocated by those who hold power.

This, too, explains why the tradition is so clear on the duty of charity and the use of wealth. Aquinasโ€™s famous distinction (II-II, q. 66, a. 2) between ownership and useโ€”between the right to hold goods and the obligation to use them for the common goodโ€”is not a loophole for State redistribution, but a moral standard for the conscience of the owner. Augustine, in De Doctrina Christiana (I, 22), frames the use of temporal goods as a means to the enjoyment of God and the service of neighbour. A property regime that fosters ownership among many, and keeps the great concentrations of wealth subject to the disciplines of competition and morality, is one that aligns with this teaching. A regime that, by State action, entrenches a few in command of the economy and excludes the many from ownership is not.

In our own time, the relevance of Leo XIIIโ€™s teaching is obvious. We live in economies where the forms of capitalism have been retained but the substance hollowed out: markets in name, but in practice dominated by a nexus of government and corporate power; competition in rhetoric, but in reality a game for those who can pay for access and influence. The same moral principles that led Leo to reject socialism oblige us to reject this corporatist order. The goal is not to level all differences of wealth, but to ensure that wealth is obtained and held by right, not by privilege; that property is widely held; that the worker has a path to independence; and that the State remembers it exists to serve persons, not to manage them.

When Augustine warned that without justice the State is but a great robbery, and when Aquinas insisted that unjust laws are not binding in conscience, they were laying the groundwork for a critique that applies as much to modern economic arrangements as to the politics of their own times. Rerum Novarum is their heir in this respect: a document that, if taken seriously, would lead us to dismantle the legal structures that sustain state-privileged monopolies, to free associations from State control, to protect the family from bureaucratic intrusion, and to make the economy once again a field in which human beings can act as responsible agents, not as units of labour power. Anything less is not Catholic social teaching, but its betrayal.

  1. You ignored the fact that Rerum Novarum was just heresy. Christianity doesn’t recommend any particular social order, and Christians in the New Testament were commanded to submit to slavery and obey their masters.


    • Thank you for your comment, David. I would first say that your position rests on an assumption that Catholic Christianity is a purely biblical religion. It is not. The Church has never confined herself to a principle of sola scriptura. From the beginning, she has drawn not only upon the sacred text but also upon the natural lawโ€”the moral truths accessible to reason itself, which even the pagans, before Christ, could discern. Saint Paul acknowledges as much when he writes that the Gentiles โ€œshow the work of the law written in their heartsโ€ (Romans 2:15). Catholic teaching is therefore the synthesis of revelation and reason, both understood as gifts of God.

      This is the context in which Rerum Novarum must be read. It is not a novelty in the sense of โ€œheresy,โ€ but the application of timeless principles to the circumstances of the modern industrial world. The right to property, the dignity of labour, the obligation of justice in exchangeโ€”these are not plucked arbitrarily from political fashion, but flow from natural law, articulated most fully by Aquinas. When Leo XIII cites homo republica antiquior est (โ€œman is older than the Stateโ€), he is not inventing a doctrine but reminding his readers that the human person, created in Godโ€™s image, precedes every social arrangement.

      You are correct that the New Testament contains commands for slaves to obey their masters. But these instructions are pastoral counsel addressed to Christians living within an unalterable Roman order. They do not amount to a divine endorsement of slavery as an institution. The Church Fathers consistently distinguished between tolerating certain conditions for the sake of peace and affirming them as just in themselves. Augustine calls slavery a consequence of sin, not a part of the original justice of creation (De Civitate Dei, XIX, 15). Aquinas agrees: โ€œServitus est poena peccatiโ€ (โ€œServitude is the punishment of sin,โ€ ST I, q. 96, a. 4). To move from this recognition to the conclusion that Christianity commands slavery as a permanent norm is a leap the Church has never made.

      Rerum Novarum stands in precisely this tradition: it does not sanctify a particular economic order as eternal, but it applies the enduring principles of revelation and reason to correct the injustices of its own time. In doing so, it reminds us that men are not resources, but persons; and that a society which treats them otherwise, whether under socialism or monopoly capitalism, is failing in justice.

      So I must respectfully answer: Rerum Novarum is not heresy. It is Catholic doctrine expressed in the face of modern problems, and it takes its authority not only from the Bible but also from the natural reason which God Himself implanted in man.


  2. It is not fully sufficient to claim that that the RC church is not solely rooted in Scripture. If you believe – as all Christians must – that the Bible was inspired by God the Holy Ghost – then you cannot just airily dismiss the Bible. There are things than even the pagans should have been able to work out from natural law, but those are not contradictory to and do not override the Bible. I don’t think it is quite true to say slavery was specifically instituted by the Law of Moses, but it was fully approved of in the Old Testament, although the slaves were all freed every 50th year, when there was a Jubilee. You might correct me slightly if i have remembered it wrong. I think Jewish slaves may have been released every 7th or Sabbatical year, and other slaves on the 50th year. What is the truth on that (I think the Bible is a little unclear on the difference between the Sabbatical year and the Jubilee year)? In any case, the real teaching of the church is that all human institutions are imperfect and that if masters and servants, or people of modern social classes, all show love, then the imperfections of human institutions are ameliorated. Maybe Leo XIII intended that?


    • Thank you again for your thoughtful reply. I would never suggest that Catholics may โ€œairily dismissโ€ the Bible. Quite the contrary: we affirm with you that the Scriptures are divinely inspired, divinitus inspirata, and profitable for teaching, reproof, and correction (2 Timothy 3:16). What I wished to underline in my earlier reply is that the Catholic Church has never treated the Bible as a free-standing authority outside of the living tradition that both produced it and interprets it.

      You raise an important point when you write that โ€œall Christians must believe that the Bible was inspired by God the Holy Ghost.โ€ That is true. But before we can identify which writings are the inspired ones, we must first ask by what authority we know the canon of Scripture at all. Nowhere in the Bible is there a list of its own contents. The Old Testament existed in several different textual forms in the first century (the Hebrew, the Greek Septuagint, other versions); the New Testament writings circulated for centuries before being formally recognised. It was the Church, guided by the same Spirit who inspired the texts, that discerned which writings were apostolic and authentic, and which were not. To say that the Bible alone is the sole authority is to overlook that the Bible itself rests upon the prior authority of the Churchโ€™s tradition. As Saint Augustine put it bluntly: Ego vero evangelio non crederem, nisi me catholicae Ecclesiae commoveret auctoritas (โ€œI would not believe the Gospel, unless the authority of the Catholic Church moved me,โ€ Contra Epistulam Manichaei, 5.6).

      On the question of slavery in the Old Testament, you recall correctly that the Mosaic Law provided for release in certain cycles. Hebrew slaves were to be freed in the Sabbatical year (the seventh year, cf. Exodus 21:2; Deuteronomy 15:12), and the Jubilee year (the fiftieth year, cf. Leviticus 25:10, 39-41) was a wider restoration, when land reverted to its ancestral owners and debts were forgiven. Foreign slaves, however, did not always share in the same protections as Hebrew bond-servants, and so the institution remained deeply imperfect even by the standards of Israelโ€™s own covenant. What is important here is that the Law of Moses does not present slavery as part of the original justice of creation, but as a tolerated institution mitigated by rules of mercy. Augustine understood this well: he calls slavery poena peccati (โ€œthe punishment of sinโ€), not part of Godโ€™s eternal will (De Civitate Dei, XIX, 15).

      The point, then, is not that Scripture is contradicted by natural law, but that the two belong together. Natural reason confirms what revelation teaches, and revelation elevates natural reason to truths beyond its own grasp. This is why the Church could, over time, come to see more clearly that the dignity of the human personโ€”already latent in Genesis 1:27, โ€œLet us make man in our imageโ€โ€”is fundamentally at odds with the perpetual enslavement of one man to another. The seed of this development is already present in Saint Paulโ€™s letter to Philemon, where he urges the master to receive the runaway Onesimus โ€œno longer as a slave, but more than a slave, a beloved brotherโ€ (Philemon 16).

      You are right to suggest that Leo XIII may have been moving within this trajectory: the Church does not imagine that all human institutions can be perfected in this fallen world, but she insists that justice and charity must temper them, and where possible must reform them. Masters and servants may indeed mitigate injustice by mutual love, but this cannot be the end of the matter. Where human law entrenches systems that treat men as resources rather than as persons, the Church will speak against it. That was Leoโ€™s intent: to say that both collectivist socialism and monopolist capitalism are betrayals of natural justice, and that the true order lies in families, associations, and property widely distributed.

      So I would end where I began: the Bible is indispensable, but it is not self-sufficient. It is the child of the Churchโ€™s tradition, not its parent. To appeal to the Bible without the Church is to wield the words of God without the very authority that guarantees they are His words at all. Catholic teaching insists on both: Scripture and tradition, revelation and reason. That is why Rerum Novarum is not heresy, but a faithful application of enduring truths to the new conditions of the modern age.


  3. The real point, I suppose, is that Leo XIII and Leo XIV are both trying to gain adherents by tacking to socialism (which Pius IX had condemned). Leo XIII was writing at a time when real communist movements were growing everywhere, and by having a socioeconomic message, he aimed to play into that. Leo XIV is doing the same thing. The Church meets Occupy Wall Street. The church does need to have a theology too, and that needs to be the main thing – but Pope Francis made clear his theology was all Cultural Marxism (there is no hell, there is no such thing as sexual immorality, Judas Iscariot was probably saved, the church should engage in interfaith dialogue with Islam and all this stuff – he apparently didn’t have any Christian belief as such). Leo XIV is holding the line on some parts of the Christian faith, and recently reaffirmed that Judas Iscariot will not be saved. He also argues that the “climate crisis” demands urgent action, and seems to be a Net Zero zealot. And he wants to get into the immigration debate–from the anti-white perspective…


    • Thank you once more for your observations. I will say first that you are quite right to note that Catholics are not obliged to treat every papal utterance as if it were inspired Scripture. The Church makes a very careful distinction here. When the Pope teaches in continuity with the tradition, especially on faith and morals, and intends to bind the whole Church, then his teaching carries the highest authority. But when he comments on contingent mattersโ€”whether economic policies, environmental science, or migration trendsโ€”he is not exercising infallibility, and Catholics may, with due respect, dissent.

      That said, I would urge caution before reducing Rerum Novarum to a sort of tactical compromise with socialism. Leo XIII was not โ€œtacking to the Left.โ€ On the contrary, he explicitly condemned socialism: peiorant omnium opificum conditionem (โ€œthey make the lot of all wage earners worse,โ€ para. 9). What he opposed was not private property or enterprise, but the abuse of property rights to reduce labourers to dependency. He was perfectly aware of Pius IXโ€™s condemnations of communism. His encyclical was an attempt to chart a course faithful to natural law: defending property, but also demanding justice, charity, and the protection of families and associations against the power of both the State and privileged capital. To dismiss this as a cynical manoeuvre is to overlook the depth of his engagement with Augustine and Aquinas.

      As for Pope Francis, I share some of your concerns. His way of speaking often blurred doctrine with fashionable slogans. His comments on hell, sexual morality, and interfaith dialogue sometimes gave the impression that revealed truths were negotiable. That was deeply damaging. But again, Catholics are not obliged to treat every interview or off-the-cuff remark as doctrine. Where he repeated the perennial teaching of the Church, we follow him. Where he wandered into speculation or echoed secular ideologies, we are not bound.

      Regarding the present Pope, if Leo XIV is reaffirming the traditionโ€”such as by insisting that Judas was lost, which is the plain testimony of Our Lord in John 17:12โ€”then Catholics rightly rejoice. If he also takes up causes like climate change or Net Zero, these must be tested not by his office alone, but by reason and evidence. The Pope can urge us to consider questions of stewardship, for the earth is indeed Godโ€™s creation; but he cannot compel us to adopt a particular policy agenda if it rests on doubtful science or unjust economics. Similarly with migration: the Gospel certainly requires charity to the stranger, but it does not require us to dissolve nations or ignore the duty of rulers to protect their own peoples. Here again, Catholics are free to apply prudential judgement.

      The main point is this: the Pope is a servant of the tradition, not its master. His authority is real, but it has limits. When he articulates the faith of the ages, he deserves our obedience. When he strays into unproven claims or ideological enthusiasm, he deserves our respectful but firm resistance. That balanceโ€”filial loyalty without servile credulityโ€”is what Leo XIII himself urged, and it is what Catholics should maintain today.
