How the American Revolution changed the future of Catholics in America

As America marks its 250th anniversary, the Revolution’s promise of religious liberty transformed Catholics from a persecuted minority into full participants in the new republic.

As the United States prepares to celebrate its 250th anniversary, the nation’s founding offers a reminder that one of the beneficiaries of the American Revolution was a religious minority once viewed with deep suspicion: Catholics.

Long before the First Amendment guaranteed the free exercise of religion, in many of Britain’s American colonies, Catholics were barred from holding public office, restricted from voting, and often prohibited from openly practicing their faith. Anti-Catholic laws, rooted in centuries of conflict between England and the Catholic Church, left many Catholics viewed with suspicion, their loyalty questioned simply because of their faith.

Yet within a generation, a Catholic priest would become the first bishop of the United States, a Catholic would sign the Declaration of Independence, and the nation’s first president would push Congress to officially recognize and authorize Catholic and Protestant chaplains.

As the United States marks its 250th anniversary, historians say the American Revolution marked a dramatic turning point for religious liberty — especially for Catholics.

Washington’s push for chaplains

When Gen. George Washington assumed command of the Continental Army in 1775, the colonies were religiously diverse but overwhelmingly Protestant. Nevertheless, Washington understood that faith was essential to the lives of the soldiers under his command.

At his urging, the Continental Congress voted on July 29, 1775, to appoint a chaplain for every regiment in the Continental Army.

The measure was practical. Chaplains preached, celebrated worship services, comforted the wounded, buried the dead, and reminded soldiers of the moral principles for which they fought.

But it also represented something larger.

For perhaps the first time in American history, the revolutionary government acknowledged that citizens serving their country should not have to abandon their religious convictions.

Although nearly all of the early chaplains were Protestant ministers, the principle established by Congress — that the government should accommodate the religious lives of its soldiers rather than suppress them — set an important precedent for religious freedom.

Father John Carroll and a new place for Catholics

Born in Maryland in 1735, John Carroll belonged to one of the few Catholic families that had managed to flourish despite legal restrictions.

Unable to receive a Catholic education in the colonies, he studied in Europe with the Jesuits before returning home as a priest.

In 1776, the Continental Congress asked Carroll to accompany Benjamin Franklin, Charles Carroll — John Carroll’s cousin — and Samuel Chase on a diplomatic mission to Canada.

His presence was deliberate.

Congress recognized that a Catholic priest could help build trust among French-Canadian Catholics and demonstrate that the American Revolution was not a Protestant movement hostile to the Catholic faith.

Although the mission ultimately failed to persuade Canada to join the Revolution, it sent an important message: Catholics had a place in the American experiment.

Catholics prove their loyalty

The Revolution gave Catholics the opportunity to challenge long-held prejudices against them.

Many colonial Protestants had inherited generations of anti-Catholic sentiment from England. Catholics were often portrayed as politically unreliable because of their allegiance to the pope.

The Revolution, however, forced Americans to reconsider those assumptions.

The patriot cause depended upon an alliance with Catholic France. The Continental Congress sought support from the largely Catholic population of Quebec. And American Catholics demonstrated that they, too, were committed to independence.

One of the clearest examples was Charles Carroll of Carrollton, the only Catholic to sign the Declaration of Independence.

A wealthy Maryland planter, Charles Carroll had long faced legal restrictions because of his faith, including limits on holding public office under British rule. By affixing his name to the Declaration, he risked both his considerable fortune and his life in support of the patriot cause.

Charles Carroll’s signature became a powerful answer to those who questioned whether Catholics could be loyal citizens of the new republic, demonstrating that devotion to the Catholic faith and commitment to American independence could go hand in hand.

Washington’s vision of religious liberty

Washington’s commitment to religious liberty became even clearer after the Revolution.

Writing in 1790 to the Hebrew Congregation in Newport, Rhode Island, Washington rejected the idea that religious minorities merely deserved tolerance. Instead, he wrote that the government of the United States “gives to bigotry no sanction, to persecution no assistance.”

Those words represented a profound departure from the European model, where governments often granted limited tolerance while still favoring one established religion.

Washington envisioned something different: equal protection for citizens regardless of their faith.

For Catholics, whose ancestors had endured generations of legal discrimination under British rule, the promise carried enormous significance.

Carroll becomes first American bishop

That same spirit shaped the future of the Catholic Church in the United States.

In 1789, Pope Pius VI appointed Father John Carroll the first bishop of the United States.

Rather than viewing American democracy with suspicion, Carroll embraced the opportunities offered by constitutional protections for religious liberty.

He established Georgetown College, promoted Catholic education, encouraged the formation of parishes, and urged Catholics to become active participants in civic life.

Carroll believed the Church could flourish precisely because the government neither established nor persecuted religion.

His confidence proved well-founded.

Within decades, the Catholic Church would grow from a tiny and often mistrusted minority into one of the nation’s largest religious communities.

A legacy for the next 250 years

The American Revolution did not eliminate anti-Catholic prejudice overnight. Catholics continued to face discrimination well into the 19th century.

Yet the Revolution fundamentally changed their legal status.

The same nation that had once inherited England’s suspicion of Catholics gradually embraced the principle that citizenship did not depend upon religious affiliation.

Washington’s support for military chaplains, his rejection of religious prejudice, and his vision of equal liberty helped lay that foundation. Bishop John Carroll, in turn, demonstrated that Catholics could faithfully serve both the Church and the new republic.

Together, their stories remind Americans that religious freedom was not simply one of the nation’s founding ideals — it became one of its greatest achievements.
