Quadragesimo Anno

Background and Occasion

By 1931 the economic and political landscape of the West had changed almost beyond recognition since Rerum Novarum. The First World War had destroyed the old European order. The Russian Revolution had brought Marxist socialism into power and made it a state ideology for the first time. The Wall Street Crash of October 1929 had plunged the industrial world into the Great Depression, with mass unemployment, the collapse of banks, and the rise of authoritarian movements promising radical solutions. Mussolini’s fascist regime was a decade old in Italy; the Nazi party would seize power in Germany within two years. Liberal capitalism, which had seemed in 1891 the dominant model against which socialism contended, now appeared to many observers to have failed.

Pius XI, marking the fortieth anniversary of Leo XIII’s encyclical, judged that the principles of Catholic social teaching required restatement and development in light of these new conditions. Quadragesimo Anno was promulgated on 15 May 1931, exactly forty years after Rerum Novarum. Its drafting had been entrusted to the German Jesuit Oswald von Nell-Breuning, working with the Society’s Königswinter Circle of Catholic social thinkers — a fact that gave the encyclical a notably systematic and conceptually rigorous character.

Central Teaching

The encyclical is structured in three parts: a tribute to Rerum Novarum and an assessment of its results in the intervening forty years; a development of its doctrine in light of new conditions; and an analysis of the contemporary economic and social order with proposals for its reconstruction.

Tribute and Assessment

Pius XI begins by recalling the situation of 1891 and the achievements of Leo XIII’s intervention. Rerum Novarum had given Catholics a charter for engagement in the social question. Catholic trade unions had been organised across Europe and the Americas. Christian Democratic political movements had taken shape. Social legislation in many countries — protection of working hours, minimum wages, social insurance — had been influenced by Leo’s principles. The encyclical had also drawn Catholics away from the temptation to embrace socialism, while orienting them firmly toward the reform of capitalist excesses.

But the encyclical had been resisted as well as received, and many of its principles had not yet been put into practice. The condition of workers in many industries remained scandalous. The concentration of economic power in a small number of vast enterprises had advanced rather than receded. New forms of injustice had emerged that Leo could not have anticipated.

Development of Doctrine

The middle section of the encyclical develops several specific points of Leo’s teaching.

The right to private property is reaffirmed but its social character is made explicit. Property has both an individual aspect (the right of the owner to acquire, use, and dispose) and a social aspect (the obligation to use property in a way consistent with the common good). These two aspects are not in competition; they are integral to the right itself. Both extremes — the individualism that would deny the social obligations of property, and the collectivism that would deny private ownership — are rejected.

The just wage is given a more elaborated treatment. Pius XI maintains Leo’s doctrine that the wage must be sufficient to support the worker and his family in reasonable comfort, but he adds two further considerations: the condition of the business (a wage that would bankrupt the enterprise harms everyone, including the workers), and the economic common good (wages must support a level of employment compatible with the welfare of the whole community). These three considerations — needs of the worker, condition of the firm, common good of the economy — must be held together in a balanced judgment of the just wage.

The Principle of Subsidiarity

The encyclical’s most original and influential contribution is the formal articulation of the principle of subsidiarity, in a passage that has become the locus classicus of the doctrine.

The principle holds that what individual persons can accomplish by their own initiative should not be taken from them and assigned to the community; and what smaller and lower associations can accomplish should not be assigned to a greater and higher association. To withdraw from individuals and smaller communities what they can rightly do by their own enterprise is a grave evil and a disturbance of right order; the proper function of any larger and higher association is to help (subsidium) the lower and smaller associations, not to absorb or destroy them.

Subsidiarity is not a doctrine of small government as such. It is a doctrine about the proper ordering of authority and initiative. Higher authorities have real and necessary functions; but they exercise those functions rightly only when they support, rather than supplant, the activity of persons, families, and intermediate associations. The state must not absorb into itself everything that families, parishes, neighbourhood organisations, workers’ associations, and businesses can do for themselves. To do so would be to deprive these lower communities of their proper life and to overburden the higher authority with tasks for which it is not suited.

The principle has had vast consequences. It is the foundation of Catholic resistance to totalitarian socialism and to the more recent expansions of the regulatory state. It also limits any merely individualist response: subsidiarity protects the rights and functions of associations as well as individuals.

Critique of Capitalism and Socialism

Pius XI subjects both the dominant economic systems of the day to extended critique. Capitalism, as it had developed in the preceding century, had produced an extreme concentration of economic power in a small number of financial and industrial interests. The “free market” had increasingly become the captured market — dominated not by genuine competition but by the strategic decisions of a few. This concentration of economic power had translated into political power, with grave consequences for the common good. The encyclical’s analysis here is sharp: economic dictatorship, the unrestrained pursuit of profit, the reduction of human labour to a mere factor of production, are condemned without qualification.

Socialism is also subjected to fresh analysis. Communist socialism, with its open rejection of religion and its programme of violent class struggle, is condemned in absolute terms — no Catholic may embrace it. But the encyclical addresses with particular care a milder form of socialism that had emerged in some Western countries: democratic, non-revolutionary, willing to operate within parliamentary institutions. Pius XI acknowledges that this mitigated socialism had moved away from many of the original Marxist positions; some of its proposals — public ownership of certain natural monopolies, social insurance, regulation of working conditions — were not in themselves incompatible with Catholic teaching. But socialism as a philosophy of human life — its materialism, its understanding of society as a mere instrument of production, its disregard for the religious and familial dimensions of human existence — remains incompatible with Christianity. The famous formulation: “no one can be at the same time a sincere Catholic and a true socialist.”

A Reconstruction of the Social Order

The most distinctive proposal of the encyclical is its sketch of an alternative to both capitalism and socialism: a social order organised around what Pius XI called vocational groups or corporations. These would bring together workers and employers within each trade or industry, under public oversight but with substantial self-governance, to regulate the conditions of work, set just wages, and order the productive activity of their sector for the common good. The model drew on the medieval guilds and on the Catholic social thought of the previous century.

This proposal has had a complex history. It was widely associated, in the 1930s, with the corporativist economic structures of fascist Italy and (to a lesser extent) Salazarist Portugal. Pius XI was careful to distinguish his proposal from the fascist version, which subordinated worker and employer alike to state control; but the association has nonetheless coloured later reception. Subsequent Catholic social teaching has moved away from the specific institutional proposal while retaining the underlying principles: collaboration rather than class struggle between workers and employers, intermediate institutions between the individual and the state, the moral ordering of economic life.

Theological Significance

Quadragesimo Anno is the second great pillar of modern Catholic social teaching, alongside Rerum Novarum. Its contribution of the principle of subsidiarity has been incorporated into the foundational vocabulary of Catholic moral and political reflection, and has had influence well beyond the Catholic world — being explicitly written into the constitutional principles of the European Union, for example.

The encyclical also gave Catholic social thought a more developed conceptual structure, distinguishing carefully between underlying principles (which are permanent) and contingent applications (which are open to revision as circumstances change). This methodological clarity has made it possible for subsequent encyclicals to develop the tradition without breaking with it.

For the manual tradition on this site, Quadragesimo Anno together with Rerum Novarum forms the indispensable backdrop to any treatment of social ethics. Their principles have been reaffirmed and extended in every major social document since: Mater et Magistra (1961), Pacem in Terris (1963), Populorum Progressio (1967), Laborem Exercens (1981), Centesimus Annus (1991), Caritas in Veritate (2009).
