How the American Revolution changed the future of Catholics in America
American Revolution’s promise of religious liberty transformed Catholics from a persecuted minority into full participants in the new republic. Washington’s push for chaplains led Congress to appoint a chaplain for each regiment, establishing a precedent that soldiers could keep their faith. Father John Carroll became the first Catholic bishop of the United States and served on a diplomatic mission, showing Catholics had a place in the new nation. Revolution allowed Catholics to prove their loyalty and challenge anti‑Catholic prejudice that had barred them from public office and voting.

The American Revolution reshaped the status of Catholics in the United States, moving them from a legally marginalized group to recognized participants in the new nation’s civic and religious life. By embracing principles of religious liberty, leaders such as George Washington and John Carroll laid the groundwork for the rapid growth of Catholic institutions and the broader acceptance of Catholic citizens. 1
In the British colonies, Catholics faced extensive legal barriers: they were barred from public office, denied voting rights, and often prohibited from openly practicing their faith. Anti‑Catholic statutes reflected centuries of English‑Catholic conflict and fostered deep suspicion of Catholic loyalty. 1
When General George Washington took command of the Continental Army in 1775, he advocated for the appointment of chaplains for each regiment. Congress approved this on July 29, 1775, establishing a precedent that the government would accommodate soldiers’ religious convictions rather than suppress them. Although early chaplains were predominantly Protestant, the policy signaled an emerging commitment to religious freedom. 1
Maryland‑born John Carroll, educated in Europe, was invited by the Continental Congress in 1776 to accompany a diplomatic mission to Canada. His presence was intended to reassure French‑Canadian Catholics and demonstrate that the Revolution was not hostile to Catholicism. After the war, Pope Pius VI appointed Carroll as the first bishop of the United States in 1789, and he founded Georgetown College, promoted Catholic education, and encouraged active civic participation. 1
Catholics used the Revolution to counter accusations of political unreliability. The alliance with Catholic France and the involvement of Catholic soldiers highlighted their patriotism. Notably, Charles Carroll of Carrollton, the sole Catholic signer of the Declaration of Independence, risked his wealth and life to support independence, providing a powerful rebuttal to anti‑Catholic prejudice. 1
In a 1790 letter to the Hebrew Congregation in Newport, Washington declared that the government “gives to bigotry no sanction, to persecution no assistance,” extending the principle of equal protection to all faiths, including Catholics who had endured centuries of discrimination. This stance reinforced the revolutionary commitment to religious freedom. 1
Although anti‑Catholic bias persisted into the 19th century, the Revolution fundamentally altered Catholics’ legal standing. The combination of Washington’s policies and Carroll’s leadership enabled the Catholic Church to expand from a small, mistrusted minority into one of America’s largest religious communities over the following centuries. 1*
How did the American Revolution redefine Catholic civic participation?
The American Revolution changed Catholic civic participation less by creating “Catholics in government” overnight, and more by removing legal barriers that had limited Catholic worship and civil standing, replacing them with constitutional protections of religious liberty—which then made sustained public civic involvement possible for Catholics over time.
In many British-American colonies, Catholic life had been constrained by law and social pressure. In Maryland, for example, Catholic worship was “forbidden” once Anglicanism became established, and Catholics faced penalties that included double taxation, confiscation of property, loss of voting rights, and efforts to ensure children were raised as Protestants.
At the same time, Catholic writers note that earlier “toleration” in some places could exist—but the line between toleration and persecution remained fragile, meaning Catholics could not assume liberty would last.
A key redefinition came through the Revolution’s replacement of “religious proscriptions by law” with broader liberty of conscience. The Catholic Encyclopedia on New York states that the “Revolution of 1776 overthrew entirely the system of government churches and all religious proscription by law,” and that the State Constitution of 1777 provided “general religious liberty.”
It further describes how Revolutionary-era legislation implemented that principle by requiring equality among denominations and adding safeguards so the state would not interfere with the internal life of churches. The 1784 legislative framework is presented as:
How that redefined Catholic civic participation: Catholics could now participate in the civic order without needing to accept that their religion would be legally disadvantaged or policed as a threat to public life. Instead, Catholic institutions could be organized as recognized corporate bodies, with legal protections for worship and internal governance.
Maryland is especially relevant because it had both a Catholic presence and a reputation in the Catholic historical narrative for early religious freedom. The Encyclopedia article on Maryland credits Catholic patriot participation and highlights the state’s 1776 Bill of Rights protections. It reports that Maryland declared:
But it also notes a compromise: the legislature could lay “a general and equal tax for the support of the Christian religion,” while individuals designated where their share would go.
So the Revolution redefined Catholic participation in two ways at once:
This helps explain why Catholic civic participation expanded in practice even while Catholics could still perceive uneven freedom from state to state.
Once legal constraints loosened, Catholics were able to show loyalty and civic engagement in a way that earlier legal regimes discouraged or punished. A particularly clear Catholic example is John Carroll and Maryland Catholics.
The Encyclopedia entry on John Carroll preserves Carroll’s defense of Catholics to critics, stressing that Catholic blood helped “cement the fabric of independence,” and that Catholics supported the government that promised “civil and religious liberty.”
Likewise, the Maryland article claims that Catholics “warmly espoused the patriot cause” and that “the Catholics of Maryland, both clergy and laity, warmly espoused the patriot cause,” listing Catholic families among those serving in the Maryland Line.
In other words: the Revolution reframed Catholic civic participation from a status of suspicion and exclusion into a status where Catholic involvement could be openly patriotic and publicly recognized—because the new legal order aimed to protect worship and conscience rather than enforce a uniform state church.
Catholic participation was not limited to voting or office-holding; it also involved building the institutions needed for Catholic life under a plural society. A later historical assessment notes that although Catholics’ worship was protected by the federal constitution, “the practice of their religion involved more than the Mass,” requiring deliberate cultivation “from cradle to grave.” As a result, Catholic communities built “churches, monasteries, convents, and seminaries,” and especially “a network of parish schools, colleges, and universities.”
That institutional building is a form of civic participation: it creates durable public goods (education, charity structures, schools) and locates Catholic identity within civic space rather than behind legal barriers.
The Revolution also forced structural changes inside the Church in the United States. The Encyclopedia on the Archdiocese of Baltimore explains that “after the Revolution” it was “plain that the United States could not conveniently remain subject in spirituals to a superior in England,” and describes the steps taken to petition and secure authority for John Carroll and the U.S. missions.
This ecclesial reorganization mattered civically because it supported a stable, coherent Catholic community life within the new political order—making it easier for Catholics to participate confidently in the nation’s public sphere, rather than operating under fragmented or foreign jurisdictional arrangements.
The American Revolution redefined Catholic civic participation by:
Ultimately, the Revolution’s legal and institutional effects made Catholic civic engagement less an act of tolerated exception and more the normal outcome of a government that, at least in principle, recognized freedom of conscience and did not require Catholics to treat their religion as socially illegitimate.
