Overview
A Catholic political-theological tradition that treats the post-French-Revolution settlement, including its religious-liberty arrangements and its assumption that politics is downstream of popular consent, as a category mistake about what political authority is, and proposes instead that political institutions take their shape from theological truth claims that liberal procedure was never competent to evaluate.
Also known as: Church-Guided Statist
History
Integralism is best understood not as a fixed doctrine but as a recurring Catholic intellectual reflex that activates whenever the post-1789 liberal political order looks vulnerable, and goes back into dormancy when it doesn't. That reflex has been triggered three times: in the post-Revolution reaction of the early nineteenth century, in the late-nineteenth-century papal-Magisterium reaction to liberal-democratic state formation, and in the post-2010 Anglo-American revival. Each iteration has carried the same analytical core (politics is subordinate to revealed truth; liberal procedure is incompetent at theological questions) into different historical conditions, with different results. The founding nineteenth-century figures, Joseph de Maistre, Louis de Bonald, Juan Donoso Cortés, and Cardinal Henry Edward Manning in the English context, built the tradition's analytical infrastructure in response to the European liberal-democratic institutional development that had been steadily reducing Catholic political influence. Maistre and Donoso Cortés are also foundational for traditional conservatism more broadly; integralism is what traditional conservatism becomes when it adopts an explicitly Catholic political-theological vocabulary rather than the more secular Burkean one [see the Traditional Conservatism dossier section on the Maistre-Donoso Cortés lineage]. The motivating sentiment was loss, and that has shaped everything since.
The late-nineteenth-century papal Magisterium did most of the heavy intellectual work. Pope Pius IX's Syllabus of Errors (1864) rejected a long list of secular-liberal political commitments. Pope Leo XIII's Immortale Dei (1885) developed the canonical Catholic political-theological framework for relating church and state. The same encyclical ecosystem, especially Rerum Novarum (1891) and the later Quadragesimo Anno (1931), is also load-bearing for distributism, which functions as the economic program integralism tends to endorse when it gets specific about property arrangements [see the Distributism dossier section on the shared papal-encyclical foundations]. Pope Pius X's Pascendi Dominici Gregis (1907) articulated the anti-modernist Catholic position. The early-twentieth-century French Action Française under Charles Maurras, the Iberian Carlist tradition, the various Latin American Catholic-traditionalist political movements, and the broader European Catholic-traditionalist intellectual ecosystem all carried forward integralist commitments through different national vocabularies.
The 1920s-1930s period saw integralism take political form, and the company it kept then is part of the tradition's contemporary problem. The 1929 Lateran Treaty between the Vatican and Mussolini's Italy established institutional church-state cooperation inside the Italian Fascist regime, supplying the institutional template that Franco's 1937 Decree of Unification adapted when it absorbed the Carlists into the FET y de las JONS, bringing Catholic-traditionalist integralist content into a fascist regime form [see the Falangism dossier section on the Carlist absorption and the Lateran Treaty parallel]. Franco's post-Civil-War Spanish state institutionalised Catholic political infrastructure. Various Latin American post-1930s Catholic-traditionalist political movements developed parallel integralist apparatus. The overlap between integralism and authoritarian-Catholic political movements is the historical record the tradition cannot quite get out from under, and the contemporary revival has to argue against it rather than around it.
Vatican II (1962-1965) changed the institutional landscape. The Council's commitments to religious liberty, ecumenical dialogue, and engagement with modern liberal-democratic institutional life pushed orthodox integralist commitments to the margins of mainstream Catholic political theology. Since then the integralist tradition has been split. Catholic-traditionalist communities that reject Vatican II's liberal-political commitments (the Society of Saint Pius X most prominently) hold one side. Catholic-traditionalist intellectual currents that work within post-Vatican-II Catholic institutional infrastructure while maintaining integralist analytical commitments hold the other. The split has not narrowed.
The contemporary integralist revival, developing since roughly 2010, has been concentrated in Anglo-American Catholic intellectual life. Adrian Vermeule's legal-political-philosophical work, especially Common Good Constitutionalism (2022), supplied the canonical contemporary American statement. The argument runs nearly parallel to Khomeini's Islamic Government (1970) in its structural move (revealed truth has priority over procedural legitimacy), even though the two traditions reach the conclusion through different theological vocabularies and would not recognize each other as allies [see the Autocratic Theocracy dossier section on Vermeule and Khomeini as parallel statements]. The broader post-liberal Catholic intellectual current (Patrick Deneen, Sohrab Ahmari, and various integralist-adjacent figures) has expanded the analytical content. The post-2010 American integralist revival overlaps significantly with the paleoconservative intellectual ecosystem, and Patrick Deneen's Why Liberalism Failed (2018) is the contemporary bridging text between the two traditions [see the Paleoconservatism dossier section on the integralist-paleoconservative ecosystem]. The Catholic-traditionalist publishing infrastructure, First Things in its more integralist moments, the various integralist-aligned online publications, and the broader traditionalist book-publishing apparatus, carries the contemporary intellectual content.
Outside Anglo-American Catholic contexts, contemporary integralism has presence in Latin American Catholic intellectual life, in Eastern European Catholic-traditionalist currents (particularly in Poland and Hungary), and in smaller Catholic-traditionalist intellectual networks across multiple national contexts. The shape of all of this is intellectual rather than political: the tradition has influence among Catholic intellectuals without anything resembling a political coalition that could implement its program.

Modern Manifestations
Contemporary integralism survives most in Anglo-American Catholic intellectual life. Adrian Vermeule's legal-political-philosophical work, the broader post-liberal Catholic intellectual current (Patrick Deneen, Sohrab Ahmari, the various contemporary integralist-adjacent intellectual figures), and the Catholic-traditionalist publishing ecosystem (First Things in its more integralist moments, the various integralist-aligned online publications including The Josias, the Catholic-traditionalist book-publishing infrastructure) carry forward contemporary integralist intellectual content.
In academic and intellectual life, contemporary integralism lives at Catholic intellectual infrastructure: Harvard Law School (through Vermeule's influence), the University of Notre Dame (through post-liberal intellectual infrastructure), the Catholic University of America, various smaller Catholic intellectual institutions, and the broader Catholic-traditionalist academic ecosystem. The contemporary trajectory has been upward through the 2015-present period.
In political contexts, contemporary integralism has intellectual influence without explicit political footprint. The various contemporary populist-right political movements (particularly Hungarian Fidesz under Orbán, the various contemporary American Catholic-aligned political infrastructure) have integralist intellectual debts; explicit integralist political infrastructure has been limited.
Outside Anglo-American Catholic contexts, contemporary integralism has presence in Latin American Catholic intellectual life (integralist intellectual currents within Argentine, Brazilian, and various other Latin American Catholic intellectual ecosystems), in various Eastern European Catholic-traditionalist intellectual currents (particularly in Poland and Hungary where Catholic-traditionalist political infrastructure has been active), and in smaller Catholic-traditionalist intellectual networks across multiple national contexts.
In contemporary online and broader cultural ecosystems, integralism circulates through the contemporary Catholic-traditionalist online intellectual infrastructure: the various Catholic-traditionalist podcasts and YouTube channels, the substantial Twitter and broader social-media infrastructure around contemporary integralist-aligned intellectual figures, and the broader online Catholic-traditionalist cultural ecosystem.
Real-World Debates
Through this lens, religious and political authority should be integrated rather than substantially-separated. The contemporary integralist position supports state recognition of Catholic Christianity as foundational political infrastructure, state implementation of natural-law-based political design, and constraint on religious pluralism in conditions of conflict between religious traditions and Catholic natural-law commitments. The empirical record of historical institutional integration has been mixed; the contemporary tradition has been working out the historical-analytical implications.
Adrian Vermeule's Common Good Constitutionalism proposes natural-law-based constitutional interpretation, in tension with the originalist constitutional-interpretation infrastructure that has dominated the post-1985 American conservative legal movement. The contemporary American Catholic intellectual current has been engaged with this debate; the question of whether natural-law-based constitutional interpretation can be implemented within American constitutional-institutional infrastructure has been contested.
Integralism is in tension with religious-liberty commitments. The orthodox integralist position holds that religious liberty should be conditioned on alignment with Catholic natural-law commitments; the more pragmatic contemporary integralist position has been more flexible on specific religious-liberty questions. The question of how to reconcile integralist commitments with religious pluralism in contemporary American institutional infrastructure has been contested.
Integralism supports state policy directed at family-traditional formation and natural-law-based institutional infrastructure. The contemporary policy menu includes child-tax-credit and family-supportive tax policy, constraints on abortion and reproductive-rights infrastructure, constraints on gender-related institutional accommodation, and state support for Catholic-religious-institutional infrastructure.
Integralism has intellectual debts to Catholic social teaching (particularly Pope Leo XIII's Rerum Novarum and Pope Pius XI's Quadragesimo Anno) and is more economically-interventionist than the post-WWII conservative-libertarian institutional infrastructure. The contemporary integralist position supports state intervention to protect family-traditional economic infrastructure, constraints on multinational-corporate concentration, and economic-policy direction at natural-law-based human-flourishing commitments.
Criticisms & Blind Spots
Strongest Critique
The integralist analytical contribution, running from Leo XIII's Immortale Dei (1885) through the contemporary Vermeule-Pappin engagement with liberal political theory, articulates a substantive challenge to the post-French-Revolution settlement's assumption that political authority is downstream of popular consent rather than of theological truth claims, and that challenge is one serious political-philosophical work on the foundations of liberal proceduralism (MacIntyre, Sandel, and parts of the post-liberal literature) continues to engage on its merits. The standing critique comes from inside the broader Western political-philosophical tradition. The standing challenge, articulated across the Western liberal-and-classical-conservative spectrum, is that integralism's subordination of political to religious authority produces real difficulty engaging with the genuinely pluralistic conditions of contemporary American and Western society. American religious-cultural life has been pluralistic throughout American history. Contemporary integralist analytical infrastructure has not seriously engaged this pattern, and the failure to engage is structural rather than incidental. The standing critique from inside the Catholic tradition itself is that integralism's rejection of Vatican II religious-liberty commitments conflicts with post-Vatican-II Catholic Church development. Pope Francis's public statements distancing the contemporary Church from integralist political commitments have clarified the institutional position. Contemporary integralist responses vary: some currents accept Francis's position, some reject it, some try to interpret it away. None of these responses have closed the gap. A second critique, from the American conservative-libertarian tradition, is that integralism's economic-interventionist commitments conflict with the conservative-libertarian economic-policy framework that defined the post-WWII American conservative coalition. The post-2016 populist-right turn has produced coalition difficulty between integralist intellectual commitments and the traditional conservative-libertarian institutional infrastructure, and the difficulty has not gone away. A third critique, from the progressive side, is that integralism's natural-law commitments would constrain contemporary civil-rights commitments around reproductive rights, gender-related institutional accommodation, and religious-liberty for non-Catholic religious traditions. This is essentially correct as a description of what integralism implies. The tradition's defenders sometimes try to soften this; the founding texts do not really support the softening.
Blind Spots
The most expensive blind spot is the relationship between integralist commitments and the pluralistic conditions of contemporary American and Western society. The integralist political program works most coherently in conditions of Catholic-religious-cultural homogeneity. American religious-cultural infrastructure has been pluralistic throughout American history and is becoming more so. The contemporary tradition has not reflected on this empirical pattern with anything like the seriousness the analytical implications warrant. A second blind spot is the historical empirical record of integralist-influenced governance. That record is mixed at best. Various pre-Vatican-II European Catholic-conservative governments. The overlap between integralism and authoritarian-Catholic political movements through the 1930s. Catholic institutional achievement alongside liberal-democratic erosion and human-rights costs to communities outside the privileged Catholic tradition. Contemporary integralist engagement with this record has been uneven, and the parts the tradition prefers to discuss are not the parts that most need discussing. A third blind spot is the relationship between integralism's Catholic-specific intellectual infrastructure and the broader contemporary post-liberal intellectual current. The two traditions overlap, the distinctions are contested, and the contemporary engagement with the boundary question has been partial. The cost of leaving this unsettled is that integralism risks being absorbed into a broader post-liberal current that does not actually share its commitments. A fourth blind spot is the question of how integralist commitments would actually be institutionally implemented in contemporary American political infrastructure. The American First Amendment is a structural constraint integralism cannot wish away. Contemporary integralist responses vary: some currents propose First Amendment reinterpretation, others accept current religious-liberty infrastructure while pursuing cultural mobilisation toward integralist commitments. Neither response is fully convincing, and the tradition has not been honest with itself about the structural difficulty. Finally, integralism has tended to underweight the relationship between its commitments and the American Protestant-religious-cultural infrastructure that has shaped American national-cultural development. American religious-cultural life has been Protestant-dominated throughout American history. Integralist commitments produce structural tension with this context, and the tradition has not really developed a serious account of what it owes to the Protestant Christian Americans whose cooperation it would need.
Internal Tensions
The deepest internal disagreement is over how integralism could plausibly be implemented in the American context at all. The orthodox position holds that genuine integralist institutional development requires a Catholic-religious-institutional foundation the contemporary United States simply lacks. The more pragmatic position holds that integralist-influenced institutional development can be implemented within contemporary American infrastructure even where the Catholic foundations are absent, on the theory that natural-law arguments can travel under non-religious labels. The orthodox position is more honest about the prerequisites. The pragmatic position is more likely to make actual political inroads. Both have a point, and the tradition has not resolved the disagreement. A second tension runs between contemporary integralism and the broader Catholic Church's post-Vatican-II development. The orthodox integralist position rejects Vatican II's liberal-political commitments. The more pragmatic position works within post-Vatican-II Catholic institutional infrastructure while maintaining integralist analytical commitments. Pope Francis has been openly unsympathetic to integralist political development, which has clarified the institutional position without resolving the intellectual one. A third tension runs between integralism and the broader contemporary post-liberal intellectual current. The orthodox integralist position is specifically Catholic in its analytical infrastructure. The broader post-liberal current is less specifically religious. Where exactly the line falls between specifically-Catholic integralist positions and broader post-liberal positions remains contested, and the contest matters because it determines whether the tradition can build coalitions or has to go it alone. A fourth tension runs between integralism and cultural-religious pluralism. American cultural-religious infrastructure has been pluralistic throughout American history, which produces structural tension with integralist commitments. Contemporary responses vary. Some integralist currents defend specifically Catholic political infrastructure while accepting pluralism in other religious-cultural contexts, which is a softer position than the founding texts would support. Other currents defend more comprehensive natural-law institutional infrastructure that would constrain various non-Catholic religious-cultural commitments, which is more consistent but harder to sell. Finally there is the tension between intellectual rigour and coalition-political reach. The contemporary integralist intellectual infrastructure has produced real influence inside Catholic intellectual contexts and very limited reach outside them. The tradition is working out whether to deepen the specifically Catholic intellectual infrastructure at the cost of further isolation, or to modify the Catholic content to enable broader coalitions at the cost of what makes integralism distinctive. Neither path is obviously the right one.
Reading List
Vermeule's 2022 book by a Harvard Law professor and Catholic convert, arguing that American constitutional law should be reread through pre-liberal natural-law categories. The most fully developed contemporary integralist statement inside Western legal academia; provocative, often criticized as institutionally evasive, and the document the contemporary debate organizes around.
Leo XIII's 1885 papal encyclical, the canonical pre-Vatican II statement that the state owes worship to God and should recognize the Catholic Church as the true religion. The doctrinal foundation contemporary integralists work from; useful to read in its original form to see how far the contemporary tradition diverges from Vatican II's Dignitatis Humanae.
Deneen's 2018 surprise bestseller arguing that contemporary liberalism's pathologies follow from its founding metaphysical premises rather than being accidental failures. The diagnostic chapters land harder than the prescriptive ones; the book that made post-liberal thought legible to general readers and brought integralism into the public conversation.
MacIntyre's 1981 attack on post-Enlightenment moral philosophy, arguing that contemporary ethical discourse is the wreckage of a coherent Aristotelian-Thomistic tradition. Not formally integralist, but the philosophical foundation contemporary Catholic integralists keep returning to; the closing 'St Benedict' paragraph has become the tradition's recurring touchstone.
The Cistercian-monk-edited online publication where contemporary integralist political theology actually develops. Useful as a primary source: you can see the position arguing with itself across hundreds of essays, working out what integralism means in 2026 conditions rather than 1885 ones.
Ahmari's 2023 popular case for using state power against corporate concentration on grounds adjacent to integralist political theology. The contemporary economic-policy face of post-liberalism; useful because Ahmari connects the integralist intellectual program to specific policy fights (labor law, antitrust, family policy) other integralist texts handle only abstractly.
