# Catholicism The Roman Catholic Church — the largest single Christian communion, with roughly 1.3 billion adherents, governed by the Pope (Bishop of Rome) and structured around the magisterial authority of the apostolic episcopate, the seven sacraments, and the integration of scripture, tradition, and magisterium as three sources of authoritative teaching. Catholicism's distinctive features include papal primacy, the deposit of faith (scripture + tradition), the seven sacraments (Baptism, Confirmation, Eucharist, Reconciliation, Anointing of the Sick, Holy Orders, Matrimony), apostolic succession through the episcopate, mariology (Marian dogmas including the Immaculate Conception and Assumption), purgatory, and an elaborated moral-theological tradition grounded in natural law. In US right-wing politics, Catholicism's footprint is large and rising — six of nine current Supreme Court justices are Catholic, the Federalist Society's legal infrastructure is heavily Catholic, [[Integralism]] and [[Catholic Post-Liberalism]] have become significant intellectual currents on the right, and Catholic-conservative networks (Heritage's [[Project 2025]] contingent, the Napa Institute, the EWTN media universe) constitute a major arm of the contemporary religious right. ## Founding and origins Catholic tradition traces the Church's institutional origin to Jesus's commissioning of Peter ("upon this rock I will build my church") and to the apostolic mission. From the 1st through the early 4th century, the church developed without a single institutional center — bishops in major sees (Rome, Antioch, Alexandria, Jerusalem, Constantinople after 330) carried regional authority. Rome's primacy emerged gradually through (a) its association with the martyrdoms of Peter and Paul, (b) its position in the imperial capital, (c) the influence of figures like Leo I (440–461) and Gregory I (590–604) in shaping the papal office, and (d) the gradual decline of imperial authority in [[the West]]. The Great Schism of 1054 — the mutual excommunications between the Roman patriarchate and the Patriarchate of Constantinople — formalized the long-developing East-West rupture, separating what would become Roman Catholicism from Eastern Orthodoxy. The split crystallized different theological emphases (the *filioque* clause, papal primacy vs conciliarity, leavened vs unleavened Eucharistic bread, clerical celibacy), different liturgical traditions, and different relationships with imperial authority. The medieval Catholic Church integrated religious, intellectual, and political authority across Western Christendom: the papal office served as supreme spiritual authority, religious orders (Benedictines, Franciscans, Dominicans, etc.) carried theological and pastoral work, scholastic theology (Aquinas, Bonaventure, Scotus) developed Catholic intellectual life, and the canon law tradition shaped the medieval legal order. The Protestant Reformation (1517–) fractured Western Christianity into Catholic and Protestant communions. The Council of Trent (1545–1563) responded with the Counter-Reformation — clarifying doctrine, reforming clerical discipline, founding new religious orders (Jesuits, Capuchins, etc.), and producing the catechism and Tridentine liturgical reforms that shaped Catholic life for the next four centuries. The First Vatican Council (1869–1870) defined papal infallibility on matters of faith and morals when pronouncing *ex cathedra*. The Second Vatican Council (1962–1965) produced sweeping liturgical, ecclesiological, and ecumenical reforms — the vernacular Mass, increased lay participation, dialogue with other religious traditions, religious-liberty affirmation, and a substantial reframing of Catholic engagement with modernity. Vatican II's reception remains contested within the Church. ## Core beliefs and distinctives **Theological core.** Standard Christian Trinitarian monotheism plus distinctive Catholic doctrines: - **Papal primacy and infallibility** — the Bishop of Rome as universal pastor with supreme jurisdiction; the doctrine of papal infallibility on faith and morals when pronouncing *ex cathedra* - **Apostolic succession** — the unbroken line of episcopal ordination from the Apostles - **Three sources of authority** — Scripture, Sacred Tradition, and Magisterium (the teaching authority of the Pope and bishops) - **Seven sacraments** — Baptism, Confirmation, Eucharist, Reconciliation, Anointing of the Sick, Holy Orders, Matrimony - **Transubstantiation** — the doctrine that the substance of bread and wine becomes the substance of Christ's Body and Blood in the Eucharist - **Marian dogmas** — Mary as Mother of God (Theotokos), Perpetual Virgin, Immaculate Conception (defined 1854), bodily Assumption (defined 1950) - **Communion of saints** — relationships across the living, the dead, and those in heaven; the practice of invoking saints' intercession - **Purgatory** — a state of purification after death for those who die in God's grace but in need of further purification - **Natural law moral theology** — a Thomist-derived framework holding that moral truths are accessible to human reason through reflection on human nature, independent of revelation **Practices.** The Mass as central liturgical action; sacramental life structured around the Catholic calendar (Advent, Christmas, Lent, Easter, Ordinary Time); private prayer (rosary, novenas, devotions to saints); pilgrimage; veneration of relics and images (distinguished doctrinally from worship); the lay-religious-clerical distinction; clerical celibacy (Latin Rite); religious orders structuring contemplative and active religious life. **Catholic Social Teaching.** A distinct tradition originating with Leo XIII's *Rerum Novarum* (1891), developed through subsequent papal encyclicals (Pius XI's *Quadragesimo Anno*, John XXIII's *Mater et Magistra*, John Paul II's *Centesimus Annus*, Benedict XVI's *Caritas in Veritate*, Francis's *Laudato Si'* and *Fratelli Tutti*). Core principles include human dignity, the common good, subsidiarity, solidarity, preferential option for the poor, and the universal destination of goods. Catholic Social Teaching sits awkwardly with US right-wing political economy on many issues (labor, immigration, climate, capital punishment) and supports US right-wing political theology on others (abortion, family structure). ## Major internal divisions Catholicism is institutionally unified under papal authority, but contains significant internal variation: - **Rites and particular churches** — the Latin (Roman) Rite is the largest; 23 Eastern Catholic Churches in full communion with Rome maintain distinct liturgical, theological, and disciplinary traditions (Byzantine Catholic, Maronite, Chaldean, Syro-Malabar, Ukrainian Greek Catholic, etc.). - **Liturgical and theological tendencies** — traditionalist Catholics (often attached to the Traditional Latin Mass, restored as the Vetus Ordo by Benedict XVI's *Summorum Pontificum* 2007 and significantly restricted by Francis's *Traditionis Custodes* 2021); mainstream postconciliar Catholics; progressive Catholics emphasizing Vatican II reforms. - **Religious orders** — Jesuits, Dominicans, Franciscans, Benedictines, Carmelites, Opus Dei, Legionaries of Christ, and many others each carry distinct charisms and theological emphases. - **Schismatic and irregular groups** — the Society of St. Pius X (SSPX, in irregular canonical status until ongoing reconciliation efforts), sedevacantist groups (who reject the validity of recent popes), Old Catholic Church (1870 schism over papal infallibility, now mostly liberal/progressive), Polish National Catholic Church. - **Geographic and cultural variation** — Latin American Catholicism (with its Marian devotional intensity and historical engagement with liberation theology); European Catholicism in long-term institutional decline; African Catholicism in rapid growth; Asian Catholicism in scattered communities; US Catholicism with its own distinctive history. ## Demographic footprint **Global:** ~1.3 billion Catholics (2020) — the largest single Christian communion; over 50% of all Christians globally. Largest national Catholic populations: Brazil (~120M), Mexico (~98M), the Philippines (~85M), the United States (~71M), Italy (~55M). **United States:** ~20% of US adults — roughly 71 million Catholics, the second-largest religious bloc after Protestants taken collectively. The US Catholic population is internally differentiated: white Catholics (~58% of US Catholics) lean Republican, Hispanic Catholics (~36%) lean Democratic but with significant rightward drift since 2020. US Catholic institutional infrastructure is substantial: 17,000 parishes, 196 dioceses and archdioceses, 6,000 parochial schools, 240+ Catholic colleges and universities, the largest non-governmental healthcare network in the country (Catholic hospitals provide roughly 1 in 6 US hospital beds). ## Right-wing politics tributaries Catholicism's footprint in contemporary US right-wing politics is large and rising — arguably the most consequential single religious-coalitional development of the past decade. Major tributaries: **Catholic SCOTUS majority.** Six of the nine current US Supreme Court justices were raised Catholic ([[John Roberts]], [[Clarence Thomas]], [[Samuel Alito]], [[Brett Kavanaugh]], [[Amy Coney Barrett]], plus [[Neil Gorsuch]] — who was raised Catholic and now identifies Episcopalian). This concentration is historically unprecedented and shapes the Court's engagement with religious-liberty cases, abortion (the 2022 *Dobbs* decision overruling *Roe*), and contraception cases. **Federalist Society and Catholic legal infrastructure.** [[Federalist Society]] networks are heavily Catholic in personnel and intellectual lineage. The infrastructure of Catholic-conservative legal advocacy — [[Becket Fund]], [[Alliance Defending Freedom]] (Protestant-led but with significant Catholic involvement), the Thomas More Society, the law schools at Notre Dame, Catholic University, Ave Maria — provides the institutional vehicle for Catholic legal influence on the right. **Catholic-integralist and post-liberal intellectual movement.** A significant strand of contemporary right-wing intellectual life is explicitly Catholic-integralist or Catholic-post-liberal: [[Adrian Vermeule]] (Harvard Law, common-good constitutionalism), [[Patrick Deneen]] (Notre Dame, *[[Why Liberalism Failed]]*, *Regime Change*), [[Sohrab Ahmari]] (*The Unbroken Thread*), [[Rod Dreher]] (*[[The Benedict Option]]*, *Live Not by Lies*). The movement explicitly challenges American liberal-individualist political theology with Catholic-traditionalist alternatives. See [[Integralism]] and [[Catholic Post-Liberalism]] for the ideological tracking. **Catholic converts in MAGA circles.** A distinctive recent pattern: prominent figures converting to Catholicism explicitly as alternative to liberal modernity. [[JD Vance]] (received 2019, Catholic-traditional/integralist-adjacent), [[Sohrab Ahmari]] (received as Catholic having been raised Muslim), [[Candace Owens]] (received 2024), and various younger right-wing intellectuals. The "convert pipeline" from atheist/Protestant/Muslim into traditional Catholicism is itself a distinctive feature of contemporary right-wing religious life. **Pro-life movement infrastructure.** Catholic institutional support for the pro-life movement — both grassroots (Catholic dioceses, Knights of Columbus, parish-based activism) and elite (Catholic legal advocacy, Catholic intellectual production) — is foundational to the broader US pro-life coalition. **EWTN and Catholic conservative media.** The Eternal Word Television Network and its broader media universe (Catholic radio, the National Catholic Register, *[[First Things]]* though formally interreligious) constitutes a substantial conservative-Catholic media ecosystem. Politically distinct from but interpenetrated with the broader Christian-conservative media environment. **Tensions with Pope Francis.** US Catholic-right relationship with Pope Francis (2013–) is significantly strained — over Francis's economic teaching, immigration framing, environmental encyclicals, and traditionalist-liturgy restrictions. Some US Catholic-right figures have openly questioned Francis's legitimacy or pastoral judgment; the Catholic-right has positioned itself partly in tension with the magisterium it formally accepts. **Hispanic Catholic rightward drift.** The most consequential demographic-political story for US Catholicism in the 2020s: Hispanic Catholic voters, historically a Democratic constituency, have moved sharply rightward in 2020 and 2024. The drivers include social-conservative positions on abortion and family, economic positioning, and disaffection from progressive cultural framings. **Catholic Right against the Catholic Left.** US Catholicism's internal political division — Catholic liberals (USCCB lay-organizing arm, Catholic social-justice tradition, Catholic Worker, sister networks) vs Catholic conservatives (the SCOTUS infrastructure, EWTN, integralist intellectual movement) — is itself a major axis of US religious-political life. ## Connections - [[Christianity]] — parent religious tradition - [[Eastern Orthodoxy]] — sibling apostolic-tradition communion separated at the 1054 Great Schism - [[Integralism]] — the ideological movement that has become the most distinctive Catholic contribution to contemporary US right-wing intellectual life - [[Catholic Post-Liberalism]] — the broader intellectual project of Catholic-tradition-informed critique of US liberal political theology - [[Religious Liberty]] — the legal framework Catholic-conservative legal infrastructure has been instrumental in shaping - [[Federalist Society]] — the legal infrastructure heavily populated by Catholic conservatives - [[Becket Fund]] — Catholic-led religious-liberty litigation organization ## See also - [[Protestantism]] — the religious tradition the Reformation produced in tension with Catholicism - [[Eastern Orthodoxy]] — sibling apostolic tradition - [[Oriental Orthodoxy]] — non-Chalcedonian apostolic tradition - [[Theocracy]] — Foundations regime-type entry; Catholic-integralist political theory engages theocracy questions explicitly
