The common wisdom that “There will never be an American pope” went up in white smoke on May 8, 2025, when Cardinal Robert Prevost, a boy from the South Side of Chicago and a graduate of Villanova University, was elected pontiff and took the name Leo XIV.
Now, on the eve of America’s Semiquincentennial, as if to underscore how much has changed, the American pope has been awarded the National Constitution Center’s Liberty Medal. Pope Leo accepted the award at the Vatican on April 30. On Friday, in a ceremony at the National Constitution Center on Independence Mall, the pontiff will address the audience live from the Vatican in a speech that will be livestreamed globally.
The medal, according to the center’s interim president and CEO, Vince Stango, will celebrate how “[i]n formal Vatican statements and public addresses, His Holiness has affirmed that peace cannot exist without freedom of religion, freedom of thought, and freedom of expression, principles that closely align with constitutional protections guaranteed by the First Amendment.”
One reason an American pope was long unthinkable is that American principles have not always aligned with Catholic principles. The proud American refusal to establish the Catholic Church as the national religion flew in the face of traditional Catholic teaching that the church should ensoul the body politic.
That was never going to happen in the United States, of course. Not even close. And so the question then became, from the Catholic point of view, what to say about the American model that included the First Amendment, with its coordinated guarantees of the “free exercise” of religion and the nonestablishment of religion by Congress.
Rome’s response has changed over time. In the late 1800s, Pope Leo XIII noted with approval the religious situation of Catholics in the United States, yet cautioned against the error that separation between the church and the civil power was to be the norm. By the 1950s, though, some Catholic thinkers were claiming the American model, in fact, stated the ideal, reasoning that the First Amendment guarantee of “free exercise” is necessary for a person to honor his God-imposed duties.
By now, even though the Second Vatican Council (1962-1965) stated that it was leaving the church’s traditional teaching “untouched,” the nonestablishment of religion and a legal guarantee of individual and group free exercise of religion, subject to just limitations for the common good, constitute the norm proposed by the Catholic Church to the world as we know it.
In speaking to the Spanish Parliament on June 8, for example, Pope Leo insisted that laws must respect “freedom of thought, conscience and religion, a fundamental right that protects the most intimate sphere of the person. The freedom upon which the contemporary state is built, if it is authentic, recognizes the religious dimension of the human person.”
In the ceremony on Independence Mall on Friday, Pope Leo will address a nation in which, for the first time in its history, it is becoming socially acceptable to oppose the free exercise of religion for some people. Litigation that threatens to cancel people’s freedom to live according to their conscience becomes more common. The seal of confession, long protected in the United States, is under assault, and the threat is real. In his address to the Spanish Parliament, Pope Leo warned against the withdrawal of that protection, and the warning needs to be echoed in the United States.
It would be one of history’s great ironies for an American pope to call his country back to a principle that his church learned, in part, from America.
Religious liberty is not the only American principle on the American pope’s mind, as his message to the 2026 graduates of his alma mater makes clear. “This being the 250th anniversary of the United States of America, I would invite you to recall in a special way the guiding principles of the foundations of our nation: ‘We hold these truths to be self-evident: that all [people] are created equal; that they are endowed by our Creator with certain inalienable rights, and among those are Life, Liberty and the pursuit of happiness.’”
The principles of the First Amendment are to be cherished, but prior to those principles, the pope has reminded us, are the principles of the Declaration of Independence around which the nation was formed in 1776. And while the declaration does indeed attest to the nation’s commitment to the people’s Creator-given right to liberty, the outstanding principle of the declaration to which President Abraham Lincoln later found the nation “dedicated” since 1776 was that all people are “created equal.”
When Lincoln summoned the American nation to rededicate itself to the equality of all persons, he did so for good reason: Unless we are related to one another as equals, we are related to one another as fractions to wholes. The three-fifths clause of the original U.S. Constitution gave effect to slavery, a grievous injustice removed by the 13th Amendment in concert with the other Reconstruction amendments. These amendments constitutionalized the nation’s earlier commitment to our having been “created equal,” but not everyone is a believer in the equality of all people.
Today, Americans are divided over the declaration and, specifically, the claim that we are “created equal.” Human equality is said by some to be a self-evident lie, and even among those who pay it lip service, commitment to the basic equality of all people is undermined by identity politics, race-based priorities, and blood guilt.
Pope Leo, though, is not in doubt about the equality of all people. In his first encyclical, Magnifica Humanitas, he writes that we are equal in “ontological dignity, which is neither acquired nor earned, nor does it need to be justified.” This immutable and foundational equality is true of all people because we are, without exception, “created in the image and likeness of God.”
And this is another truth Americans need to reclaim.
In order to reclaim it, we need to understand that human equality was never meant to state something empirical or measurable about people. The equality declared by the declaration and celebrated by Lincoln, and fully constitutionalized by the Reconstruction amendments, depends on what is spiritual in a person, represented by the radical Christian judgment that underneath the obvious and often wonderful diversity of people lies a universal sameness in being created in the divine image.
When G.K. Chesterton was asked, “What is America?” he gave a characteristically smart answer that has been debated ever since: “America is a nation with the soul of a church. America is the only nation in the world founded on a creed. That creed is set forth with dogmatic and even theological lucidity in the Declaration of Independence.”
Robert Prevost, now Pope Leo, was formed, in part, in that “church” with its declarational creed. He was also, and first, formed in the Catholic Church, with its commitment to the universal equality of all people.
What the American pope can do now, in a way no other person on earth can, is to remind Americans that the equality to which their nation has been dedicated since 1776 depends on what Christianity has shown the world: that even the least, in worldly eyes, are equals in God’s eyes.
