Catholic Church in the United States
The Catholic Church in the United States is part of the worldwide Catholic Church in full communion, communion with the pope, who as of 2025 is Chicago, Illinois-born Pope Leo XIV, Leo XIV. With 23 percent of the United States' population , t ...
began in the colonial era, but by the mid-1800s, most of the Spanish, French, and Mexican influences had demographically faded in importance, with Protestant Americans moving west and taking over many formerly Catholic regions. Small Catholic pockets remained in Maryland, Alabama, Florida, and Louisiana, but scarcely anywhere else.
However, after 1840, American Catholicism grew through immigration from Europe, especially from Germans and Irish. After 1890, Catholic immigrants from Southern and Eastern Europe arrived in large numbers. The Church set up an elaborate infrastructure, based on local parishes organized into dioceses run by bishops appointed by the Pope. Each diocese set up a network of schools, colleges, hospitals, orphanages and other charitable institutions.
Many priests and nuns arrived from France and Ireland. By 1900, America was producing a sufficient supply of priests and nuns. The Catholic population was primarily working-class until after World War II when it increasingly moved into white-collar status and left the inner city for the suburbs. After 1960, the number of priests and nuns fell rapidly and new

As the Catholic colleges and universities matured, questions were raised about their adherence to orthodox Catholic theology. After 1980, the Catholic bishops became involved in politics, especially on issues relating to abortion and sexuality.

Colonial era
In general
The history of Catholicism in the United States – prior to 1776 – often focuses on the
13 English-speaking colonies along the Atlantic seaboard, as it was they who declared independence from Great Britain in 1776, to form the United States of America. However, this history – of Catholicism in the United States – also includes the French and Spanish colonies, because they later became part of the

which increased further to 20,000 by 1765.

The current dioceses of the United States are derived from a number of colonial-era dioceses. The following traces the succession of dioceses up to the first diocese that was completely contained in United States territory.
* Spanish dioceses gave rise to many successors in the United States:
**The Spanish parts of the mainland United States were originally part of the
Diocese of Mexico established in 1530, and later the
Diocese of Durango when it split in 1620.
*** California became part of the
Diocese of Sonora in 1779. The Diocese of Both Californias, based in San Diego, was established in 1840. After the Mexican–American War, the Mexican portion was split off in 1849, with the United States portion becoming the
Diocese of Monterey.
*** New Mexico remained part of the Diocese of Durango until after it was annexed by the United States, with the
Diocese of Santa Fe established in 1850.

Michael Breidenbach has argued that "a central reason, if not ''the'' central reason, why Protestants believed Catholicism was the greatest single threat to civil society and therefore why its adherents could not be tolerated...was the pope's claim (and Catholics' apparent acceptance of it) that he held temporal power over all civil rulers, including the right to depose a secular authority." Breidenbach argues that American Catholics did not in fact hold this view, but opponents largely ignored that. Colonial charters and laws contained specific proscriptions against Catholics.

/Duke of York, their English Catholic landlords) were initially barred from settling in some of the colonies (before 1688, for example, Catholics had not arrived in New England), though "New York had an Irish Catholic governor,
Thomas Dongan, and other Catholic officials." Middleton also notes: at one time or another, five colonies "specifically excluded Catholics from the franchise: Virginia, New York, Maryland, Rhode Island, and South Carolina." Throughout the Revolution American Catholic priests remained under the jurisdiction of the
Bishop of the London District. But even during the colonial period the successive bishops had accepted the charge reluctantly, and were too far away to exercise much control. During the war, however, when the jurisdiction was in the hands of Bishop James Talbot, the brother of the Earl of Shrewsbury and coadjutor to Bishop
Richard Challoner, he refused to have any communication with those who were his American ecclesiastical subjects. This was because neither he nor Challoner had any sympathy with the American rebel Catholics. They did not realize that American Catholics (though rebels) were rendering, as John Carroll said later, a service to their English Catholic brethren. This lack of communication, technically at least, proved a blessing in disguise, and removed all possibility of the accusation that American Catholics were receiving orders from an English Catholic bishop. At the close of the war, however, Bishop Talbot went so far as to refuse to give faculties to two Maryland priests who asked to return home. This eventually enabled Rome to make entirely new arrangements for the creation of an American diocese under American bishops.
John Carroll's says this about Catholic participation: "Their blood flowed as freely, in proportion to their numbers, to cement the fabric of independence as that of their fellow citizens. They concurred with perhaps greater unanimity than any other body of men in recommending and promoting from whose influence America anticipates all the blessings of justice, peace, plenty, good orders, and civil and religious liberty." Some Catholics were more prominent than others. Thomas Fitzsimons was Washington's secretary and aide-de-camp. General Moylan was quartermaster general and afterwards in command of a cavalry regiment.
John Barry is regarded as the father of the American navy. Another notable was
Thomas Lloyd.
The French alliance had a considerable effect upon the fortunes of the American Catholic Church. Washington, for example, issued strict orders in 1775 that "

This amendment included the wording, "Congress shall make no law respecting an establishment of religion, or prohibiting the free exercise thereof..." This amendment officially granted freedom of religion to all American citizens, and began the eventual repeal of all anti-Catholic laws from the statute books of all of the new American states.
Following the Revolutionary War the Jesuit Fathers under the leadership of John Carroll, S.J. called several meetings of the clergy for the purpose of organizing the Catholic Church in America. The meetings, called the General Chapters, took place in 1783 and were held at White Marsh Plantation (now Sacred Heart Church in Bowie, MD). Deliberations of the General Chapters led to the appointment of John Carroll by the Vatican as Prefect Apostolic, making him superior of the missionary church in the thirteen states, and to the first plans for Georgetown University. Also at White Marsh, the priests of the new nation elected John Carroll as the first American bishop on May 18, 1789.

19th century

The Catholic population of the United States, which had been 35,000 in 1790, increased to 195,000 in 1820 and then ballooned to about 1.6 million in 1850, by which time Catholics had become the country's largest denomination. Between 1860 and 1890 the population of Catholics in the United States tripled, primarily through immigration and high birth rates. By the end of the century, there were 12 million Catholics in the United States.
During the mid 19th century, a wave of immigrants from Europe arrived from Ireland and Germany, as well as England and the Netherlands. From the 1880s to 1914 a "new" wave arrived from Italy, Poland and Eastern Europe. Substantial numbers of Catholics also came from
French Canada during the mid-19th century and settled in

Many Catholics stopped practicing their religion or became Protestants. However, there were about 700,000 converts to Catholicism from 1813 to 1893.
Archdiocese of Baltimore
Because Maryland was one of the few regions of the colonial United States that was predominantly Catholic, the first diocese in the United States was established in Baltimore. Thus, the
Diocese of Baltimore achieved a pre-eminence over all future dioceses in the U.S. It was established as a diocese on November 6, 1789, and was elevated to the status of an archdiocese on April 8, 1808.

Parochial schools
The development of the American Catholic parochial school system can be divided into three phases. During the first (1750–1870), parochial schools appeared as ad hoc efforts by parishes, and most Catholic children attended public schools. During the second period (1870–1910), the Catholic hierarchy made a basic commitment to a separate Catholic school system. These parochial schools, like the big-city parishes around them, tended to be ethnically homogeneous; a German child would not be sent to an Irish school, nor vice versa, nor a Lithuanian pupil to either. Instruction in the language of the old country was common. In the third period (1910–1945), Catholic education was modernized and modeled after the public school systems, and ethnicity was deemphasized in many areas. In cities with large Catholic populations (such as Chicago and Boston) there was a flow of teachers, administrators, and students from one system to the other.
Catholic schools began as a program to shelter Catholic students from Protestant teachers (and schoolmates) in the new system of public schools that emerged in the 1840s.

called for a Constitutional amendment that would prohibit the use of public funds for "sectarian" schools. Grant feared a future with "patriotism and intelligence on one side and superstition, ambition and greed on the other" which he identified with the Catholic Church. Grant called for public schools that would be "unmixed with atheistic, pagan or sectarian teaching." No such federal constitutional amendment ever passed, but most states did pass so-called "
Blaine Amendments" that prohibited the use of public funds to fund parochial schools and are still in effect today.

In supremo apostolatus''. Its main focus was against slave trading, but it also clearly condemned racial slavery:
:We, by apostolic authority, warn and strongly exhort in the Lord faithful Christians of every condition that no one in the future dare bother unjustly, despoil of their possessions, or reduce to slavery Indians, Blacks or other such peoples.
However, the American church continued in deeds, if not in public discourse, to support slaveholding interests. Some American bishops misinterpreted ''In Supremo'' as condemning only the slave trade and not slavery itself. Bishop John England of Charleston actually wrote several letters to the Secretary of State under President Van Buren explaining that the Pope, in In Supremo, did not condemn slavery but only the slave trade.
One outspoken critic of slavery was Archbishop John Baptist Purcell of Cincinnati, Ohio. In an 1863 ''Catholic Telegraph'' editorial, Purcell wrote:
:"When the slave power predominates, religion is nominal. There is no life in it. It is the hard-working laboring man who builds the church, the school house, the orphan asylum, not the slaveholder, as a general rule. Religion flourishes in a slave state only in proportion to its intimacy with a free state, or as it is adjacent to it."
During the Civil War, American bishops continued to allow slave-owners to take communion. Some, like former priest
Charles Chiniquy, claimed that Pope Pius IX was behind the Confederate cause, that the American Civil War was a plot against the United States of America by the Vatican. The Catholic Church, having by its very nature a universal view, urged a unity of spirit. Catholics in the North rallied to enlist. Nearly 150,000 Irish Catholics fought for the Union, many in the famed
Irish Brigade, as well as approximately 40,000 German-Catholics, and 5,000 Polish-Catholic immigrants. Catholics became prominent in the officer corps, including over fifty generals and a half-dozen admirals. Along with the soldiers that fought in the ranks were hundreds of priests who ministered to the troops and Catholic religious sisters who assisted as nurses and sanitary workers.
After the war, in October 1866, President Andrew Johnson and Washington's mayor attended the closing session of a plenary council in Baltimore, giving tribute to the role Catholics played in the war and to the growing Catholic presence in America.
African-American Catholics
Because the South was over 90% Protestant, most African-Americans who adopted Christianity became Protestant; some became Catholics in the Gulf South, particularly Louisiana. The French Code Noir which regulated the role of slaves in colonial society guaranteed the rights of slaves to baptism, religious education, communion, and marriage. The parish church in New Orleans was unsegregated. Predominantly black religious orders emerged, including the Sisters of the Holy Family in 1842. The Church of Saint Augustine in the Tremé district is among a number of historically black parishes. Xavier University, America's only historically-black Catholic institute of higher learning, was founded in New Orleans by Saint
Katherine Drexel in 1915.
Maryland Catholics owned slaves starting in the colonial era; in 1785, about 3,000 of the 16,000 Catholics were black. Some owners and slaves moved west to Kentucky.

James Augustine Healy was the first African American to become a priest. He became the second bishop of the Diocese of Portland, Maine in 1875. His brother,
Patrick Francis Healy, joined the Society of Jesus (Jesuits) at the novitiate in Frederick, Maryland in 1850. Because of the rising threat of Civil War and the Jesuit custom of pursuing further studies in Europe, he was sent to Belgium in 1858. He earned a doctorate at the university of Leuven, becoming the first American of African descent to earn a doctorate; and he was ordained a priest in Liege, France in 1864. Immediately following the Civil War he was ordered to return to the U.S. and began teaching at Georgetown University, becoming its president in 1874.
In 1866, Archbishop
Martin J. Spalding of Baltimore convened the
Second Plenary Council of Baltimore, partially in response to the growing need for religious care for former slaves. Attending bishops remained divided over the issue of separate parishes for African-American Catholics.

Labor union movement
Irish Catholics took a prominent role in shaping America's labor movement. Most Catholics were unskilled or semi-skilled urban workers, and the Irish used their strong sense of solidarity to form a base in unions and in local Democratic politics. By 1910 a third of the leadership of the labor movement was Irish Catholic, and German Catholics were actively involved as well.

warned the American hierarchy not to export their unique system of separation of church and state. In 1898 he lamented an America where church and state are "dissevered and divorced," and wrote of his preference for a closer relationship between the Catholic Church and the State.

James Cardinal Gibbons (July 23, 1834 – March 24, 1921) was an American Catholic prelate who served as Apostolic Vicar of North Carolina from 1868 to 1872, Bishop of Richmond from 1872 to 1877, and as Archbishop of Baltimore from 1877 unti ...
, Pope Leo XIII condemned other forms of Americanism. In response, Gibbons denied that American Catholics held any of the condemned views.
Leo's pronouncements effectively ended the Americanist movement and curtailed the activities of American progressive Catholics. The Irish Catholics increasingly demonstrated their total loyalty to the Pope, and traces of liberal thought in the Catholic colleges were suppressed. At bottom it was a cultural conflict, as the conservative Europeans were alarmed mostly by the heavy attacks on the Catholic church in Germany, France and other countries, and did not appreciate the active individualism, self-confidence and optimism of the American church. In reality Irish Catholic laymen were deeply involved in American politics, but the bishops and priests kept their distance.

'', who first recognized the urgency of the moment. Burke had long argued for a national outlook and sense of unity among the country's Catholics. The war provided the impetus to initiate these efforts. The Catholic hierarchy was eager to show its enthusiastic support for the war effort. In order to better address challenges posed by World War I, the American Catholic hierarchy in 1917 chose to meet collectively for the first time since 1884.
In August 1917, on the campus of The Catholic University of America in Washington, D.C., Burke, with the backing of Cardinal Gibbons and other bishops, convened a meeting to discuss organizing a national agency to coordinate the war effort of the American Catholic community. One hundred and fifteen delegates from sixty-eight dioceses, together with members from the Catholic press and representatives from twenty-seven national Catholic organizations attended this first meeting.
The result of the meeting was the formation of the
National Catholic War Council, "to study, coordinate, unify and put in operation all Catholic activities incidental to the war." An executive committee, chaired by Cardinal

Bishops' Program of Social Reconstruction
Following the war many hoped that a new commitment to social reform would characterize the ensuing peace. The Council saw an opportunity to use its national voice to shape reform and in April 1918 created a Committee for Reconstruction.
John A. Ryan wrote the Bishops' Program of Social Reconstruction.
On February 12, 1919, the National Catholic War Council issued the "Bishops' Program of Social Reconstruction," through a carefully planned public relations campaign. The plan offered a guide for overhauling America's politics, society, and economy based on Pope Leo XIII's Rerum Novarum and a variety of American influences.
The Program received a mixed reception both within the Church and outside it. The National Catholic War Council was a voluntary organization with no canonical status. Its ability to speak authoritatively was thus questioned. Many bishops threw their support behind the Program, but a few, such as Bishop William Turner of Buffalo and William Henry O'Connell of Boston, opposed it. O'Connell believed some aspects of the plan smacked too much of socialism. Response outside the Church was also divided: labor organizations backed it, for example, and business groups criticized it.

Catholic Conference on Industrial Problems
The
Catholic Conference on Industrial Problems (1923–1937) was conceived by Fr. Raymond McGowan as a way of bringing together Catholic leaders in the fields of theology, labor, and business, with a view to promoting awareness and discussion of Catholic social teaching. Its first meeting was held in Milwaukee. While it was the venue for important discussions during its existence, its demise was due in part to lack of participation by business executives who perceived the dominant tone of the group as anti-business.
Hospitals
As the urban population surged in the late 19th century, the major denominations built hospitals in the cities. A large fraction of patients were Catholic immigrants, and the Church reached out to them. In 1915, the Catholic religious orders for women operated 541 hospitals. They were open to patients regardless of religion. Costs were minimized by relying heavily on the work of women students who paid tuition and nuns who had taken a vow of poverty.
In 1945, there were 685 Catholic hospitals with a bed capacity of 87,000. Fifteen years later, there were 800 hospitals with 137,000 beds. Between 1960 and 1970, the number of patients nearly doubled. By 2000, however, mergers reduced the number of smaller hospitals, while patient admissions continued to grow rapidly, with heavy federal funding from Medicare and Medicaid.
In the late 20th century the hospitals increasingly closed their training programs and relied on paid graduate nurses who had college degrees in nursing. In the 21st century, as the cohorts of nuns aged, they turned their hospitals over to lay boards thus allowing the last generation of sister administrators to retire.
1960s
The 1960s marked a profound transformation of the role of the Catholic Church in the politics.
Religion was a divisive issue during the
presidential campaign of 1960. Senator
John F. Kennedy
John Fitzgerald Kennedy (May 29, 1917 – November 22, 1963), also known as JFK, was the 35th president of the United States, serving from 1961 until his assassination in 1963. He was the first Roman Catholic and youngest person elected p ...
won the Democratic nomination. His base was among urban Catholics and polls showed they rallied to his support while most Protestants favored his opponent Richard Nixon. The old fear was raised by some Protestants that President Kennedy would take orders from the pope. Kennedy famously told the Greater Houston Ministerial Association on September 12, 1960, "I am not the Catholic candidate for President. I am the Democratic Party's candidate for President who also happens to be a Catholic. I do not speak for my Church on public matters – and the Church does not speak for me." He promised to respect the separation of church and state and not to allow Catholic officials to dictate public policy to him. Kennedy also raised the question of whether one-quarter of Americans were relegated to second-class citizenship just because they were Catholic. With his slim victory in November 1960, he broke the Protestant monopoly on the White House. ''The New York Times'', summarizing the research of pollsters spoke of a “narrow consensus” among the experts that Kennedy had won more than he lost as a result of his Catholicism. After that, objections to Catholic candidates as such were seldom heard. Still, anti-Catholicism did not disappear in November 1960; for instance, Kennedy navigated treacherous religious debates in 1961 as he sought to pass his education proposal and mollify wary American Protestants. By 2004, Catholics were split about evenly between the Protestant (George W. Bush) and the Catholic (John F. Kerry) candidates. This was still true in 2020, when

president. His religious affiliation sparked little controversy.
1970s
The number of priests, brothers and nuns dropped sharply in the 1960s and 1970s as many left and few replacements arrived. Catholic parochial schools had been built primarily in the cities, with few in the suburbs or small towns. Many continue to operate, but with the loss of so many low-cost nuns, they have to hire much more expensive lay teachers. Most inner-city parishes saw white flight to the suburbs, so by the 1990s the remaining schools often had a largely minority student body, which attracts upwardly mobile students away from the low-quality, high-violence, free public schools.

Sanctuary of refugees from Central American civil wars was a movement in the 1980s. It was part of a broader anti-war movement positioned against U.S. foreign policy in Central America. By 1987, 440 sites in the United States had been declared "sanctuary congregations" or "
sanctuary cities" open to migrants from the civil wars in El Salvador and Guatemala. These sites included university campuses.

Later 16 activists in Arizona were indicted, including Fife and Corbett in 1985; 11 were brought to trial and 8 were convicted of alien smuggling and other charges. The defendants claimed their actions were justifiable to save lives of people who would be killed and had no other way to escape.
This movement has been succeeded in the 2000s by the movement of churches and other houses of worship, to shelter immigrants in danger of deportation. The New Sanctuary Movement is a network of houses of worship that facilitates this effort.

A 2008 survey by the Pew Forum on Religion & Public Life, a project of the Pew Research Center, found that 23.9% of 300 million Americans (i.e., 72 million) identified themselves as Catholic and that 29% of these were Hispanic/Latino, while nearly half of all Catholics under 40 years of age were Hispanic/Latino. The survey also found that white American Catholics were seven times more likely to have graduated high school than Hispanic/Latino Catholics, and that over twice as many Hispanic/Latino Catholics earned under $30,000 per year as their white counterparts. According to the

According to Luis Lugo, the director of the Pew Forum on Religion and Public Life, nearly a quarter of all Catholics in the United States are foreign born. He notes: "To know what the country will be like in three decades, look at the Catholic church."
Sex abuse scandals
In the later 20th century "
..the Catholic Church in the United States became the subject of controversy due to allegations of
clerical child abuse of children and adolescents, of episcopal negligence in arresting these crimes, and of numerous civil suits that cost Catholic dioceses hundreds of millions of dollars in damages." Although evidence of such abuse was uncovered in other countries, the vast majority of sex abuse cases occurred in the United States.
Major lawsuits emerged in 2001 and subsequent years claiming some
priests had sexually abused minors.
[Bruni, p. 336.] These allegations of priests
sexually abusing children were widely reported in the news media. Some commentators have argued that media coverage of the issue has been excessive compared with media coverage of sex abuse carried out in the education system.
Some priests resigned, others were defrocked and jailed, and there were financial settlements with many victims.
One estimate suggested that up to 3% of U.S. priests were involved.
The United States Conference of Catholic Bishops commissioned a comprehensive study that found that four percent of all priests who served in the US from 1950 to 2002 faced some sort of sexual accusation.
The Church was widely criticized when it emerged that some bishops had known about abuse allegations, and reassigned accused priests after first sending them to psychiatric counseling.
[Steinfels, p. 40–46.][Frawley-ODea, p. 4.] Some bishops and psychiatrists contended that the prevailing psychology of the times suggested that people could be cured of such behavior through counseling.
Pope John Paul II responded by declaring that "there is no place in the priesthood and religious life for those who would harm the young".
[Walsh, p. 62.]
The U.S. Church instituted reforms to prevent future abuse by requiring background checks for Church employees;
because the vast majority of victims were teenage boys, the worldwide Church also prohibited the ordination of men with "deep–seated homosexual tendencies."
It now requires dioceses faced with an allegation to alert the authorities, conduct an investigation and remove the accused from duty.
In 2008, the Vatican affirmed that the scandal was an "exceptionally serious" problem, but estimated that it was "probably caused by "no more than 1 per cent" of the over 400,000 Catholic priests worldwide.

Humanae Vitae
(Latin, meaning 'Of Human Life') is an encyclical written by Pope Paul VI and dated 25 July 1968. The text was issued at a Vatican press conference on 29 July. Subtitled ''On the Regulation of Birth'', it re-affirmed the teaching of the Catho ...
'' (Human Life). In this encyclical, the Pope acknowledges the realities of modern life, scientific advances, as well as the questions and challenges these raise. Furthermore, he explains that the purpose of intercourse is both "unitive and procreative", that is to say it strengthens the relationship of the husband and wife as well as offering the chance of creating new life. As such, it is a natural and full expression of our humanity. He writes that contraception "contradicts the will of the Author of life
od Hence to use this divine gift
exual intercoursewhile depriving it, even if only partially, of its meaning and purpose, is equally repugnant to the nature of man and of woman, and is consequently in opposition to the plan of God and His holy will."
The Church says its doctrines on sexual intercourse are based on a correct reading of the
Natural law
Natural law (, ) is a Philosophy, philosophical and legal theory that posits the existence of a set of inherent laws derived from nature and universal moral principles, which are discoverable through reason. In ethics, natural law theory asserts ...
: intercourse must at once be both the renewal of the consummation of marriage and open to procreation. If each of these postulates are not met, the act of intercourse is, according to Natural Law, an ''objectively'' grave sin. Therefore, since artificial contraception expressly prevents the creation of a new life (and, the Church would argue, removes the sovereignty of God over all of Creation), contraception is unacceptable. The Church sees abstinence as the only objective moral strategy for preventing the transmission of HIV.
