The history of the Catholic missions in America is that of the largest geographical expansion Christianity has ever known: in less than three centuries, the Catholic faith spread from the West Indies to Patagonia and from the rivers of Canada to the coasts of California. Begun in 1493 in the wake of the caravels of Christopher Columbus, it is inseparable from the European conquest — with its real violence — yet it cannot be reduced to it: as early as 1511, religious publicly denounced the enslavement of the Indians, and in 1537 Pope Paul III solemnly proclaimed that the peoples of the New World are truly men, free and capable of faith.
At the heart of this history stands a founding miracle: the apparition of Our Lady of Guadalupe at Tepeyac in December 1531 — recognized by the Church: Benedict XIV, by the brief Non est equidem of 25 May 1754, made her patroness of New Spain with a proper Mass and office on 12 December, Saint Pius X proclaimed her patroness of Latin America in 1910, and Pius XII, on 12 October 1945 — the fiftieth anniversary of the 1895 coronation — proclaimed her Queen of Mexico and Empress of the Americas, then patroness of all the Americas in 1946. Within a few years, this sign precipitated the massive conversion of the Indians of Mexico — counted by the million in the Franciscan accounts of the time[1] — and made the Virgin the mother of a mestizo continent. Catholic America was thus born of an encounter, and not only of domination.
The continent saw every face of mission: the Franciscan and Dominican "spiritual conquest" of Spanish America, the Jesuit reductions of Paraguay — a veritable Guarani "Christian commonwealth" admired even by the philosophers of the Enlightenment —, the Black Robes of New France and their martyrs, the missions of California. It also gave the Church its first saints of the New World — Rose of Lima, Martin de Porres, Peter Claver, Kateri Tekakwitha — and the blood of martyrs both native, French and Spanish.
Today, America is the leading home of world Catholicism: according to the 2026 Pontifical Yearbook, 47.7% of the world's Catholics live there[2]. Brazil and Mexico are by far the two largest Catholic countries on the planet, and the election of Francis, the first pope from the New World, in 2013, sealed the shift of the Church's centre of gravity toward the South; after his death on 21 April 2025, the conclave elected on 8 May 2025 a new pope likewise from the Americas, Leo XIV (Robert Francis Prevost, born in Chicago and long a missionary then bishop in Peru). Yet this vitality faces new challenges: secularization and the surge of the Evangelical churches are shrinking practice in several countries.
Evangelizing a New World: three great missionary spaces
The American mission was not a single bloc: it unfolded in very different settings, under rival crowns, with distinct religious orders and methods. To understand this history, three great theatres must be held together, each with its own chronology and figures.
The first and most massive was Iberian America, Spanish and Portuguese. Under the patronato real — by which the papacy entrusted the Catholic kings with organizing the Church of the Indies — Franciscans, Dominicans, Augustinians and then Jesuits evangelized the Aztec and Inca empires, the West Indies, Brazil and the entire Southern Cone[3]. It is there that the bulk of today's Latin American Catholicism was born.
The second was New France: from the St. Lawrence, Jesuits, Recollects and Sulpicians carried the Gospel to the Native nations — Hurons, Iroquois, Algonquins — at the cost of a famous martyrdom[4]. The third was the great arc of the missions of the North and West: New Mexico, Texas, Franciscan California, the missions that still shape the religious map of the Southwestern United States. Added to these three settings were the later missions of islands and forests, down to the contemporary Amazon.
None of these missions was pure: all took place in the shadow of conquering empires. But all also carried an internal protest — that of the religious who defended the Indians against the settlers — and a holiness sprung from the very soil of America.
The "spiritual conquest" of Spanish America
The patronato and the first dioceses of the New World
From Columbus's second voyage, in 1493, priests accompanied the Spaniards to the West Indies. Through a series of bulls — including Inter caetera (1493) then Universalis Ecclesiae (1508) —, the papacy granted the Catholic Kings the patronato real: a privilege charging them with founding and financing the Church of the Indies, appointing bishops and sending missionaries[5]. This system bound mission and crown closely together — for the best (an unprecedented effort of evangelization) as for the worst (the subordination of the Church to colonial interests).
The first structures soon followed. In 1511, Pope Julius II erected the three first effective dioceses of the New World: Santo Domingo and Concepción de la Vega (Hispaniola), and San Juan (Puerto Rico)[6]. Mexico became an archdiocese in 1546, Lima the same year: within half a century, a complete hierarchy had taken root on a continent unknown to Europe thirty years earlier.
The Twelve Apostles of Mexico (1524)
The most famous episode of this first evangelization is the arrival, on 13 May 1524, of twelve Franciscans at Veracruz: the "Twelve Apostles of Mexico," led by Martín de Valencia[7]. The number is no accident: the minister general of the order chose them "because it is the number Christ took into his company to bring about the conversion of the world"[8]. As they entered Mexico City, according to the Franciscan chroniclers' account, Hernán Cortés himself knelt and kissed the worn habits of the friars, before the astounded Aztec nobles — a gesture said to signify that spiritual power takes precedence over the power of arms[9].
The Franciscan chronicler Motolinía (Toribio de Benavente) reports baptisms by the million in the first decades — figures Robert Ricard, in his classic study of the "spiritual conquest" (1933), discusses as exaggerated, while seeing in them the reflection of a very real mass conversion[10]. The Franciscan method favoured learning the native languages, above all Nahuatl, and forming a native elite. The Flemish lay brother Pedro de Gante, a relative of Charles V (held to be a natural son of Emperor Maximilian), founded in Mexico City the school of San José de los Naturales, where thousands of young Indians learned doctrine, music and trades[11]. This first Mexican Church, before later compromises, was a work of mutual admiration as much as of authority.
This Mexican undertaking was also the theatre of the great modern objections to the conquest — Black Legend, encomienda, Aztec sacrifices, demographic collapse. The answers hold in a few firm facts: Aztec human sacrifice is attested by the native sources themselves and the excavations of the Templo Mayor; the encomienda, which quickly became a regime of forced labour, was denounced by the Church itself — Montesinos in 1511, Las Casas, then Sublimis Deus (1537); the demographic collapse came first from epidemics against which no one then possessed any remedy; and the "Black Legend" designates the polemical exaggerations of Spain's rivals, built upon real violence that the missionaries were the first to denounce. The quantified detail of these debates is treated in the specialized article.

Our Lady of Guadalupe, Mother of the Americas (1531)
The apparitions of Tepeyac
In December 1531, barely ten years after the fall of Tenochtitlan, a Christian Indian named Juan Diego reported seeing, on the hill of Tepeyac near Mexico City, a "Lady from Heaven" who presented herself in the Nahuatl language as the Mother of the true God and asked that a shrine be raised to her[12]. As proof, roses bloomed in midwinter, and the image of the Virgin was imprinted on the tilma (cloak of agave fibres) of the visionary. The words tradition retains as the heart of the message are a maternal consolation:
« Ne suis-je pas ici, moi qui suis ta Mère ? N'es-tu pas sous mon ombre et sous ma protection ? » — Notre-Dame de Guadalupe à Juan Diego, Nican Mopohua, vers 1545-1556[13]
The conversion of a continent
The effect of Guadalupe was immense. The Virgin had not appeared in the features of a European woman, but of a young woman with a mestizo complexion, dressed in native fashion: for peoples who had just seen their gods fall, this sign said that the God of the Christians welcomed America without effacing it. Conversions, until then slow, were soon counted by the million. Guadalupe became the founding religious symbol of Mexico and, beyond, of all Latin America[14]. Juan Diego was canonized by John Paul II in 2002, and the Virgin of Guadalupe proclaimed by Pius XII Queen of Mexico and Empress of the Americas on 12 October 1945, then patroness of all the Americas in 1946. The scientific and historical dossier of the image — the tilma, the eyes, the iconography — is studied separately.
📖 See the detailed article: Our Lady of Guadalupe (1531)
The voice of the prophets: the Catholic defense of the Indians
One of the most systematically forgotten facts of this history is that the denunciation of colonial abuses was born at the very heart of the Church, and very early — before the invention of modern "human rights," and well before the Protestant powers, promoters of the Black Legend, undertook their own colonization.
The cry of Montesinos (1511)
On the fourth Sunday of Advent 1511, in Santo Domingo, the Dominican Antonio de Montesinos climbed into the pulpit before the settlers and delivered one of the most resounding homilies in the moral history of the West:
« De quel droit et avec quelle justice tenez-vous ces Indiens dans une servitude si cruelle et si horrible ? Ces Indiens ne sont-ils pas des hommes ? N'ont-ils pas des âmes raisonnables ? » — Antonio de Montesinos, homélie de l'Avent 1511, rapportée par Bartolomé de Las Casas, Historia de las Indias, livre III[15]
The scandal was such that the settlers demanded a retraction. The Dominican provincial refused. This sermon, delivered more than twenty years before the founding of the first English settlements in North America, is regarded as the birth certificate of the defence of indigenous rights in the New World[16].
Bartolomé de Las Casas, defender of the Indians
Among those who heard of this controversy, a former settler turned priest: Bartolomé de Las Casas (1484-1566)[17]. Himself first a holder of an encomienda — a royal grant entrusting a group of Indians to a settler, meant to pay for their evangelization but quickly turned into a regime of forced labour —, he underwent in 1514 a true interior conversion, renounced his Indians and devoted the rest of his life — more than half a century — to their defence[18]. A Dominican, then Bishop of Chiapas, he crossed the Atlantic many times to plead their cause before the crown, obtained the Leyes Nuevas of 1542 — the "New Laws" which forbade the enslavement of the Indians and limited the encomienda —, and published in 1552 his Brevísima relación de la destrucción de las Indias, a burning indictment of the abuses[19]. At the Valladolid controversy (1550-1551), he confronted the jurist Juan Ginés de Sepúlveda, who justified war against the Indians by their alleged natural inferiority: Las Casas defended the unity of the human race and the full humanity of the Indians. His struggle, long used against Spain by her enemies, testifies above all to a Christian self-criticism without equivalent in the other colonial empires.
📖 See the detailed article: Bartolomé de Las Casas (1484-1566)
Sublimis Deus: Paul III declares the Indians truly men (1537)
These protests rose all the way to Rome. On 2 June 1537, Pope Paul III published the bull Sublimis Deus, one of the most important texts in the history of human rights. Against those who held the Indians to be inferior beings "made to serve," the pope rules with absolute clarity:
« Les Indiens, comme tous les autres peuples qui pourraient être découverts par la suite par les chrétiens, ne doivent en aucune manière être privés de leur liberté ni de la possession de leurs biens — même s'ils ne sont pas chrétiens — et ne doivent pas être réduits en esclavage. » — Paul III, bulle Sublimis Deus, 2 juin 1537[20]
The pope affirms there that the Indians are truly men, capable of understanding the faith and desirous of receiving it, and that whatever has been done in contempt of this principle shall be "null and of no effect"[21]. It is, two centuries before the Enlightenment, a magisterial proclamation of the unity and dignity of the human race.
The School of Salamanca and the birth of the law of nations
Theological reflection accompanied action. At the University of Salamanca, the Dominican Francisco de Vitoria (c. 1483-1546) devoted his famous 1539 relectiones De Indis — his solemn annual lectures on "the Indians recently discovered" — to the question of the just titles of the conquest. His conclusion, revolutionary, founds modern international law:
« Les barbares [les Indiens] étaient véritablement propriétaires, en public comme en privé, avant l'arrivée des Espagnols ; ils n'étaient ni dépourvus de raison ni incapables de posséder. » — Francisco de Vitoria, De Indis, relectio I, 1539[22]
Vitoria denies that discovery, refusal of the faith or the emperor's authority can justify the conquest, and he sketches a law of nations (ius gentium) common to all peoples, Christian or not[23]. The School of Salamanca, with Vitoria, Domingo de Soto and Suárez, is today recognized as one of the cradles of international law and human rights — born of a missionary question.
The reductions of Paraguay: a Guarani Christian commonwealth
Birth and organization (1609)
From 1609, in the forests of the Paraná, the Jesuits undertook a missionary experiment unique in the world: the reductions (reducciones). The first, San Ignacio Guazú, was founded in 1609[24]. These were autonomous Christian villages, peopled by Guarani Indians, removed from the authority of the Spanish settlers and organized around church, school and workshop. Guarani was spoken there, community farming practised, European music taught with a virtuosity that would amaze travellers. At their peak, around 1732, thirty reductions counted nearly 141,000 inhabitants[25].
The experiment so struck European minds that a philosopher of the Enlightenment, hardly to be suspected of indulgence toward the Jesuits, cited it as an example. Montesquieu himself writes in The Spirit of the Laws — "it" being the Society, that is, the Society of Jesus:
« Il est glorieux pour elle d'avoir été la première qui ait montré dans ces contrées l'idée de la religion jointe à celle de l'humanité. » — Montesquieu, De l'esprit des lois, livre IV, chapitre 6, 1748[26]
Mbororé: the Guaranis take up arms against the slavers (1641)
The reductions were no paradise apart from the world: they had to defend themselves. The bandeirantes of São Paulo — Portuguese slave-hunters — raided the Guarani villages to sell their captives. After devastating attacks, the Jesuits obtained from the crown the right to arm the Indians. On 11 March 1641, at the battle of Mbororé, some 4,000 Guarani warriors led by the Jesuits routed a bandeirante expedition[27]. For the first time, organized Christian Indians stood up to the slave-traders — a fact which announces, in its own way, the Church's struggle against the slave trade.
Splendour and destruction (1767)
The end of the reductions came not from the Indians nor the forests, but from European politics. The Treaty of Madrid (1750) ceded seven reductions to Portugal, triggering the revolt of the Guaranis (the "Guarani War," 1754-1756). Then, in the great anti-Jesuit movement of the European courts, Charles III of Spain expelled the Society of Jesus from all his territories in 1767 (edict of 2 April 1767, executed in the missions in 1768): some 78 Jesuits left the missions, abandoning nearly 89,000 Guaranis[28]. Deprived of their priests, the reductions swiftly declined. Only majestic ruins remain, listed as world heritage — vestiges of a Christian utopia realized for a century and a half.

North America: the blood of the martyrs
New France and the Black Robes
In the north, evangelization took another face. From the St. Lawrence, the Jesuits — whom the Native Americans called the "Black Robes" — pushed deep into the forests to live among the Huron, Algonquin and Iroquois nations[29]. Their annual letters, the famous Jesuit Relations, are among the richest ethnographic sources on 17th-century North America. The leading figure of this mission is the Norman Jean de Brébeuf (1593-1649), "giant of the Huron missions," who composed a catechism and a dictionary in the Huron language and saw, it is said, seven thousand converts before his death[30].
The Canadian martyrs: Brébeuf, Jogues and companions (1642-1649)
Years before, Brébeuf had made a vow never to refuse the grace of martyrdom. His spiritual journal testifies to an intense desire to give his life, taking the word of the Psalm as his own: to render to the Lord all the good received and to take the chalice of salvation (Ps 115,12-13 Vg)[31].
Between 1642 and 1649, the war between Hurons and Iroquois carried off eight Jesuit missionaries and donnés. Isaac Jogues was tortured then killed in 1646; Brébeuf and Gabriel Lalemant suffered a dreadful torment in March 1649 during the destruction of Huronia.
- 1625-1626Arrival of the Jesuits in Huronia
Jean de Brébeuf and his companions join the Huron nations of Lake Simcoe and learn their language.
- 29 September 1642René Goupil, first martyr
The donné René Goupil is killed by the Iroquois for tracing a sign of the cross on a child.
- 18 October 1646Martyrdom of Isaac Jogues
Returned to the Mohawks after a first captivity, Isaac Jogues is killed with a blow of a hatchet.
- 16 March 1649Martyrdom of Brébeuf and Lalemant
Jean de Brébeuf and Gabriel Lalemant are tortured to death at the fall of Huronia.
- 29 June 1930Canonization by Pius XI
The eight North American martyrs are canonized together; they will be proclaimed patrons of Canada in 1940.
Pius XI canonized the eight North American martyrs on 29 June 1930; in 1940, they were declared secondary patrons of Canada[32]. Their shrine at Midland (Ontario) draws pilgrims from across North America each year: like Africa with the martyrs of Uganda, the continent bears the mark of this witness of blood.
📖 See the detailed articles: Saint Jean de Brébeuf and Saint Isaac Jogues
Kateri Tekakwitha, the Lily of the Mohawks
From this soil watered with the blood of the Black Robes soon sprang a flower of native holiness. Kateri Tekakwitha (1656-1680), daughter of a Mohawk chief and a Christian Algonquin mother, was born in what is now New York State. Orphaned and scarred by smallpox, converted and baptized at nineteen, she endured the hostility of her village and took refuge in the mission of Kahnawake, near Montreal, where she led a life of prayer, penance and consecrated virginity[33]. Dead at twenty-four, nicknamed the "Lily of the Mohawks," she was beatified by John Paul II in 1980 and canonized by Benedict XVI on 21 October 2012: she is the first Native woman of North America to be canonized — Saint Juan Diego, the Mexican Indian of Guadalupe, having preceded her as the first native saint of the Americas with his canonization in 2002[34].
📖 See the detailed article: Saint Kateri Tekakwitha (1656-1680)
The missions of the Southwest and California
Junípero Serra and the California missions
In the southwest of the continent, Spanish America pressed on through the Franciscan mission system, which still marks the place names of the United States (San Antonio, San Diego, Santa Fe, San Francisco). The central figure is the Majorcan Franciscan Junípero Serra (1713-1784), founder of the first California missions: the first, San Diego de Alcalá, was established in 1769, after a march of more than 1,400 kilometres[35]. Serra founded nine in his lifetime, of the twenty-one the Californian chain would count. His motto sums up his temperament:
« Toujours en avant, jamais en arrière. » — Saint Junípero Serra, devise (« Siempre adelante, nunca atrás »)[36]
A debated figure
Serra's work is contested today: his 2015 canonization prompted public protests, carried notably by descendants of the peoples of the Californian missions, who reproach him with the harshness of the mission regime, imposed labour and the epidemics that decimated the neophytes. The debate is real and must not be sidestepped. But the dossier is documented on both sides: his biographer Steven W. Hackel establishes that Serra also defended the Indians against settlers and soldiers — even pleading clemency for the perpetrators of the San Diego revolt (1775) — and that he travelled in person to Mexico City to hand to Viceroy Bucareli, on 13 March 1773, a thirty-two-point memorial obtaining a protective regulation for the neophytes[37]. Pope Francis canonized him on 23 September 2015 in Washington — the first canonization ever celebrated on United States soil[38]. A man's holiness does not canonize every structure of his time: it recognizes the heroic charity of a life given to the Gospel.

A land of holiness: the first saints of the New World
The surest sign that a Church is truly "planted" in a land is its saints. And America, barely evangelized, produced them very early — with a remarkable ethnic diversity, mirroring the mestizo continent. The following table gathers the first great figures of holiness of the New World.
| Saint | Dates | Place | Distinctive note | Canonization |
|---|---|---|---|---|
| Rose of Lima | 1586-1617 | Peru | First saint of the Americas | 1671, Clement X |
| Toribio de Mogrovejo | 1538-1606 | Peru | Archbishop of Lima, councils of Lima | 1726, Benedict XIII |
| Martin de Porres | 1579-1639 | Peru | Mestizo Dominican brother, charity | 1962, John XXIII |
| Peter Claver | 1580-1654 | Colombia | "Slave of the slaves" | 1888, Leo XIII |
| Kateri Tekakwitha | 1656-1680 | North America | First Native woman of North America canonized | 2012, Benedict XVI |
Saint Rose of Lima, first flower of holiness
Rose of Lima (Isabel Flores de Oliva, 1586-1617) is the first saint born on the American continent. A Dominican tertiary, she led in a hermitage at the bottom of the family garden a life of intense prayer, rigorous penance and service to the poor and the sick[39]. Dead at thirty-one, she was canonized on 12 April 1671 by Clement X, who proclaimed her principal patroness of Peru, the Americas and the Philippines[40]. Her canonization, barely a century and a half after the arrival of the first missionaries, seals the spiritual maturity of Catholic America.
📖 See the detailed article: Saint Rose of Lima (1586-1617)
Toribio de Mogrovejo and the councils of Lima
A contemporary of Rose, Toribio Alfonso de Mogrovejo (1538-1606), Archbishop of Lima, was the great organizer of the Peruvian Church. He tirelessly travelled his immense diocese, confirmed hundreds of thousands of the faithful — among them, it is said, little Rose and young Martin de Porres — and presided over the Third Council of Lima (1582-1583), which gave Spanish America a trilingual catechism in Spanish, Quechua and Aymara[41]. This concern for native languages, inherited from the Franciscans of Mexico, was one of the great pastoral achievements of American Catholicism.
Saint Martin de Porres, the brother of charity
Lima, in that half-century, was a true nursery of holiness. Martin de Porres (1579-1639), son of a Spanish hidalgo and a freed Black or Indian woman, a Dominican lay brother, embodies the humblest charity: nurse to the sick, friend of the poor and of animals, he is one of the Church's first mestizo saints. Long despised for his birth, he was canonized by John XXIII on 6 May 1962 and proclaimed patron of social justice and racial harmony[42]. His figure says what is essential about American Catholicism: a holiness that crosses every skin colour.
📖 See the detailed article: Saint Martin de Porrès (1579-1639)
Saint Peter Claver, slave of the slaves
If America was a land of slavery, it was also home to one of slavery's greatest adversaries. The Catalan Jesuit Peter Claver (1580-1654) devoted himself, at Cartagena de Indias (in present-day Colombia), to serving the African slaves landed by the thousand in the great slave port — often dying after a crossing on which, on some voyages, nearly a third perished. For forty years, he went down into the holds to tend, feed, console and catechize these men; he is estimated to have baptized nearly 300,000 people[43]. At his profession, he had signed his vow with a formula that has remained famous:
« Pierre Claver, esclave des Noirs pour toujours. » — Saint Pierre Claver, formule de profession, 1622 (« Petrus Claver, aethiopum semper servus »)[44]
Canonized by Leo XIII in 1888, he was proclaimed patron of missions to Black populations[45]. His apostolate illuminates the darker side of American history: the African slave trade, which the Church fought through the holiness of a few before solemnly condemning it in the 19th century.

From missionary Church to Latin American Church
The Council of Trent under the tropics
Spanish America applied the reform of the Council of Trent very early. The provincial councils of Mexico and Lima, in the second half of the 16th century, translated the Tridentine decrees for a new world: formation of the clergy, catechisms in native languages, organization of Indian parishes. A local Church, endowed with its universities — Lima and Mexico as early as 1551 —, took shape well before political independence.
Independence and the 19th century
The wars of independence of the early 19th century shook this Church. Bound to the crown by the patronato, it found itself torn between loyalty to Spain and allegiance to the new nations. The young republics, often won over to anticlerical liberalism, expelled religious, confiscated property and tried to subjugate the Church — as in Mexico, where the conflict culminated in the 20th century in the Cristeros war (1926-1929) and its procession of martyrs. The Latin American Church emerged impoverished but purified from this century of crises, and began to think of itself no longer as an extension of Europe, but as the proper Church of a continent.
Vatican II, Medellín and the option for the poor
The great awakening came in the 20th century. Gathered in continental conferences, the bishops of Latin America (CELAM) sought to apply the Second Vatican Council to the realities of a continent marked by poverty. The Medellín conference (1968) launched a formula destined for a great future — the "preferential option for the poor" —, taken up and clarified at Puebla (1979)[46]. This insight gave birth to fruitful currents, but also to a liberation theology some versions of which borrowed from Marxism a class analysis incompatible with the faith. The Congregation for the Doctrine of the Faith, under Cardinal Ratzinger, denounced its deviations in two instructions, Libertatis nuntius (1984) and Libertatis conscientia (1986), while reaffirming the Church's authentic preferential love for the poor[47].
Aparecida (2007) and the first American pope
The synthesis of this entire journey took place at the fifth CELAM conference, at Aparecida (Brazil) in 2007. The drafting committee of the final document was chaired by Cardinal Jorge Mario Bergoglio, Archbishop of Buenos Aires[48]. Aparecida made Latin America a continent of mission and of the missionary disciple, called to go out from itself to proclaim Christ. Six years later, on 13 March 2013, this same Bergoglio became Francis, the first pope from America and the first Jesuit pope — an event that sealed the continent's new weight in the universal Church. Already, John Paul II had sought to unite the two Americas in a single hope: signing at the basilica of Guadalupe, on 22 January 1999, the exhortation Ecclesia in America, he presented Christ there as "the way of conversion, communion and solidarity in America"[49].
📖 See the detailed articles: Pope Francis, Our Lady of Aparecida and The Church in Latin America
America, heart of world Catholicism
The figures
The result of this five-century history is without equivalent: according to the 2026 Pontifical Yearbook, 47.7% of the world's Catholics live on the American continent — nearly half of a Church that now counts more than 1.4 billion faithful[50]. Brazil and Mexico are by far the two largest Catholic countries on the planet. Latin America alone gathers the highest concentration of Catholics in the world, the direct fruit of the "spiritual conquest" and of Guadalupe.
Challenges and fragilities
This preponderance is no longer a quiet growth. Since the 2010s, the Catholic share has clearly receded in Latin America: according to a vast survey published by the Pew Research Center in January 2026, the proportion of Catholics has fallen by nine points or more in a decade in the six large countries studied — dropping to 67% in Mexico and Peru, 60% in Colombia, 58% in Argentina and only 46% in Brazil and Chile[51]. The surge of the Evangelical and Pentecostal churches and the rise of the religiously unaffiliated account for most of this ebb.
The American Church also faces violence — from Mexican drug trafficking to persecution in Nicaragua —, social inequality and internal debates on inculturation, as shown by the synod on the Amazon (2019). But, from Guadalupe to Aparecida, from the Twelve Apostles of Mexico to the first American pope, the history of the Catholic missions in America remains that of a continent which, in five centuries, has gone from mission territory to the demographic heart of Catholicism — and which today seeks a second missionary wind.

4 29Érection des trois premiers diocèses effectifs du Nouveau Monde (Saint-Domingue, Concepción de la Vega, San Juan de Porto Rico) par Jules II, bulle Romanus Pontifex, 8 août 1511 (à ne pas confondre avec la bulle homonyme de Nicolas V, 8 janvier 1455, sur les découvertes portugaises) — les trois prélats nommés aux sièges de la province ecclésiastique créée en 1504 s'étant joints à la Couronne pour en demander la suppression. Une première province (archidiocèse de Hyaguata, diocèses de Magua et de Bayuna) avait en effet été érigée par le même Jules II, bulle Illius fulciti, 15 novembre 1504, mais ne fut jamais occupée. Cf. Catholic Encyclopedia (1913), notices « Archdiocese of Santo Domingo » et « Diocese of Concepción de la Vega » (newadvent.org) ; Pedro de Leturia, Relaciones entre la Santa Sede e Hispanoamérica, Rome-Caracas, 1959. Mexico (érigé diocèse le 2 septembre 1530) et Lima sont élevés au rang d'archevêchés métropolitains par Paul III le 12 février 1546.
6Les Douze Apôtres du Mexique, conduits par Martín de Valencia, débarquent à Veracruz le 13 mai 1524 (13 ou 14 mai selon les chroniques) ; l'agenouillement de Cortés est rapporté par les chroniqueurs franciscains, au premier rang Gerónimo de Mendieta, Historia eclesiástica indiana (rédigée à la fin du XVIᵉ siècle, éd. Joaquín García Icazbalceta, Mexico, 1870). Cf. aussi Toribio de Benavente (Motolinía), Historia de los indios de la Nueva España, vers 1541, et Robert Ricard, op. cit.
7 8 9Pedro de Gante (vers 1479-1572), frère convers franciscain, apparenté à Charles Quint (tenu pour un fils naturel de l'empereur Maximilien Ier), fondateur de l'école San José de los Naturales à Mexico ; cf. Robert Ricard, La « Conquête spirituelle » du Mexique, op. cit.
11Sur les apparitions de Guadalupe (9-12 décembre 1531) et leur portée, cf. l'article spécialisé Ignispedia et Jacques Lafaye, Quetzalcóatl et Guadalupe. La formation de la conscience nationale au Mexique, Gallimard, Paris, 1974. Reconnue d'abord localement (patronne de Mexico en 1737, puis de toute la vice-royauté de Nouvelle-Espagne en 1746), Guadalupe reçoit la sanction pontificale par le bref Non est equidem de Benoît XIV (25 mai 1754) : patronne de la Nouvelle-Espagne, avec messe et office propres au 12 décembre ; patronne de l'Amérique latine (saint Pie X, 1910) ; Reine du Mexique et Impératrice des Amériques (Pie XII, message radiophonique du 12 octobre 1945, pour le cinquantenaire du couronnement de 1895), puis patronne de toutes les Amériques (1946). Cf. National Catholic Register, « Honoring Our Lady of Guadalupe: Empress of the Americas » : Pie XII lui décerne en 1945 le titre d'Impératrice des Amériques à la demande des évêques des États-Unis et du Canada. Corroboration : « In 1754 Pope Benedict XIV approved her patronage and granted her a proper feast and mass for December 12 » (Encyclopaedia Britannica, notice « Our Lady of Guadalupe »).
12 14Nican Mopohua, récit en nahuatl des apparitions attribué à Antonio Valeriano, vers 1545-1556, n. 119 : « ¿Cuix amo nican nica nimonantzin? » (« ¿No estoy yo aquí, que soy tu Madre? » — « Ne suis-je pas ici, moi qui suis ta Mère ? »). Traduction française d'après l'édition critique du texte nahuatl.
13Antonio de Montesinos, homélie du quatrième dimanche de l'Avent 1511 à Saint-Domingue, rapportée par Bartolomé de Las Casas, Historia de las Indias, livre III, ch. 3-4. Texte original espagnol : « ¿Con qué derecho y con qué justicia tenéis en tan cruel y horrible servidumbre aquestos indios? […] ¿Éstos no son hombres? ¿No tienen ánimas racionales? »
15Lewis Hanke, The Spanish Struggle for Justice in the Conquest of America, University of Pennsylvania Press, Philadelphie, 1949 — étude de référence sur Montesinos, Las Casas, Vitoria et la controverse de Valladolid. Sur les traversées de Las Casas, Hanke écrit seulement « very many times across the Ocean Sea » (p. 22), sans donner de chiffre.
16 18 19La naissance de Las Casas fut longtemps datée de 1474 ; les dépouillements d'archives ont établi le 11 novembre 1484 — H. R. Parish et H. Weidman, « The Correct Birthdate of Bartolomé de las Casas », Hispanic American Historical Review, vol. 56, n° 3, 1976, pp. 385-403 — date aujourd'hui communément retenue.
17Paul III, bulle Sublimis Deus, 2 juin 1537. Traduction française d'après le texte latin : « …dictos Indos et omnes alias gentes ad fidem Christi… libertate ac rerum suarum dominio… nec debere privari, neque servituti redigi. » Déclare les Indiens véritables hommes, libres et capables de la foi ; déclare nul tout acte contraire.
20 21Francisco de Vitoria, Relectio de Indis (relectio I), Salamanque, 1539, éd. critique L. Pereña et J. M. Pérez Prendes, CSIC, Madrid, 1967. Conclusion latine : « Restat conclusio certa, quod antequam Hispani ad illos venissent, illi erant ita veri domini, et publice et privatim » — les Indiens étaient véritables propriétaires de leurs biens et terres avant l'arrivée des Espagnols ; traduction française d'après le latin. Vitoria fonde ainsi le ius gentium.
22 23Sur les réductions guaranies : Philip Caraman, The Lost Paradise: The Jesuit Republic in South America, Seabury Press, New York, 1976 ; et notice « Reductions of Paraguay », Catholic Encyclopedia, vol.

24 25 28Montesquieu, De l'esprit des lois, livre IV, chapitre 6, 1748 — éloge des réductions jésuites du Paraguay. Verbatim : « […] il sera toujours beau de gouverner les hommes en les rendant plus heureux. Il est glorieux pour elle d'avoir été la première qui ait montré dans ces contrées l'idée de la religion jointe à celle de l'humanité. […] Elle a retiré des bois des peuples dispersés, elle leur a donné une subsistance assurée, elle les a vêtus ; et quand elle n'aurait fait par là qu'augmenter l'industrie parmi les hommes, elle aurait beaucoup fait. » (« elle » = la Compagnie de Jésus). Cf. Dictionnaire Montesquieu (ENS-Lyon), notice du livre IV, 6, qui cite ce passage au mot près.
