'Your Hands Are Full of Blood': The First American Pope Turns Scripture Against an American War

An initial wave of headlines attributed the Palm Sunday rebuke to Pope Francis, who died in April 2025. The words belong to his successor — and they carry a different, sharper weight.

On the morning of March 29, 2026, tens of thousands of worshippers filled St. Peter's Square for Palm Sunday Mass. Pope Leo XIV — born Robert Francis Prevost in Chicago, elected ten months earlier as the first American pope in the history of the Catholic Church — stood before them and delivered a homily that, within hours, had ricocheted through diplomatic channels and social media feeds worldwide [1][2].

"Brothers and sisters, this is our God: Jesus, King of Peace, who rejects war, whom no one can use to justify war," Leo said. "He does not listen to the prayers of those who wage war, but rejects them, saying: 'Even though you make many prayers, I will not listen: your hands are full of blood'" [3][4].

The passage — Isaiah 1:15 — is a prophetic condemnation of Israel's leaders in the Hebrew Bible, a text in which God tells his people that their rituals are meaningless while they perpetrate violence. That Leo chose it at a moment when the U.S.-Israeli war on Iran was entering its second month, and when senior American officials were publicly casting the conflict in Christian theological terms, was not lost on observers [5][6].

The Conflict Behind the Homily

On February 28, 2026, the United States and Israel launched surprise airstrikes across Iran, killing Supreme Leader Ali Khamenei and several other senior officials along with dozens of civilians [7]. In the four weeks since, the death toll has mounted. The Washington Post reported that nearly 1,500 Iranian civilians had been killed in U.S. and Israeli strikes that hit schools, hospitals, and other nonmilitary infrastructure [8]. The human rights organization Hengaw documented over 5,300 total deaths, including 511 confirmed civilians, in the first 18 days alone [9]. More than 3.2 million people have been internally displaced within Iran [10].

The humanitarian Norwegian Refugee Council warned that one month of war had left "millions in extreme uncertainty," with infrastructure damage disrupting supply chains for food, medicine, and fuel [10]. The near-total halt of tanker traffic through the Strait of Hormuz has triggered global food price increases as fertilizer and fuel supplies constrict [7].

Meanwhile, the Russia-Ukraine war grinds through its fourth year. UNHCR data shows Ukraine remains the world's second-largest source of refugees at 5.3 million, behind only Syria at 5.5 million [11].

'Holy War' Rhetoric at the Pentagon

What made Leo's homily land with particular force was its implicit target: not just war in the abstract, but the religious framing of this specific war by senior members of the Trump administration.

Defense Secretary Pete Hegseth has repeatedly invoked Christian faith to justify the campaign. In a CBS News interview, he said Iran "should not doubt US resolve because it is backed by the higher power," adding, "The providence of our almighty God is there protecting those troops" [12]. At a Pentagon worship service on March 25 — four days before Leo's homily — Hegseth cast the Iran conflict as a "violent holy war against God's enemies" [13].

Hegseth's rhetoric did not emerge from nowhere. In his 2020 book American Crusade, he wrote that the U.S. faces a "crusade moment" echoing the 11th-century Christian invasion of the Holy Land: "We don't want to fight, but, like our fellow Christians one thousand years ago, we must" [14].

The Military Religious Freedom Foundation reported receiving more than 200 complaints from service members across over 50 installations and every branch of the U.S. military, alleging that commanders were invoking Christian prophecy to justify the Iran war. One complaint, shared by an anonymous non-commissioned officer, claimed troops were told that the war was "part of God's plan" and that Trump was "anointed by Jesus to light the signal fire in Iran to cause Armageddon and mark his return to Earth" [15].

More than two dozen Democratic members of Congress requested a formal investigation into what they described as the use of "religious prophecy and apocalyptic theology to justify the United States' military actions in Iran" [16].

When Leo XIV declared from the altar of St. Peter's that God "does not listen to the prayers of those who wage war" and that "no one can use [Jesus] to justify war," the subtext was difficult to miss [3].

What the Pope Did — and Did Not — Say

The full text of the homily, published by OSV News, contains no reference to Iran, the United States, Israel, Russia, or Ukraine by name [4]. Leo quoted Zechariah 9:9-10 on Jesus entering Jerusalem "humble and riding on a donkey," contrasted with those "stirring up violence." He quoted Matthew 26:52 — "all who take the sword will perish by the sword." And he invoked the Italian peace advocate Bishop Tonino Bello in a closing prayer that "the tears of all the victims of violence and pain will soon be dried up like frost beneath the spring sun" [4].

In a separate blessing, Leo expressed concern for Middle Eastern Christians "suffering the consequences of an atrocious conflict" who "in many cases cannot live fully the rites of these holy days" [1].

His closing exhortation was direct: "Lay down your weapons! Remember that you are brothers and sisters!" [4]

A Snopes fact-check published after the homily rated as "Mostly False" viral social media claims that Leo had specifically "condemned" the Iran war or "rebuked Christian leaders who prayed over Trump." The Pope's actual words were a theological appeal for peace, not a point-by-point political condemnation [17]. But the distinction between universal principle and specific application is, as one Vatican observer noted, precisely the rhetorical space in which popes have always operated.

An American Pope Criticizing an American War

Leo XIV's position is historically unprecedented. No pope has ever been a citizen of the country waging the war he is criticizing. The Washington Post reported in mid-March that Leo had been "leaning on proxies" — including Cardinal Robert McElroy and Vatican Secretary of State Pietro Parolin — to make the case against the war more explicitly, while keeping his own statements at the level of moral principle [18][19].

This strategy echoes his predecessor's approach in one respect: Pope Francis rarely named specific leaders when criticizing military actions, preferring instead to speak in general terms about the evils of war while allowing context to do the interpretive work [20]. But Francis also had fewer constraints. As an Argentine pope with no personal stake in U.S. domestic politics, his criticisms of Trump on immigration ("not Christian" in 2016, "a disgrace" in 2025) could be received as coming from an external moral authority [20].

Leo, born in Chicago and holding U.S. citizenship alongside his Peruvian and Vatican passports, faces a different dynamic. Catholic World Report ran a piece in October 2025 headlined "Leo XIV: Our Anti-Americanist Pope," examining whether his nationality would permanently complicate any Vatican criticism of U.S. policy [21].

The Bishops Speak More Directly

Where Leo kept to theological generality, the U.S. Conference of Catholic Bishops did not.

Archbishop Paul S. Coakley, USCCB president, issued a statement on March 1 urging Washington, Tehran, and the international community to "resume dialogue and seek all possible paths toward a just and lasting peace" [22].

Cardinal McElroy of Washington was more pointed: "The U.S. decision to go to war against Iran fails to meet the just war threshold for a morally legitimate war in at least three requirements." He specified that the country "was not responding to an existing or imminent and objectively verifiable attack by Iran," that the war's "goals and intentions are absolutely unclear," and that "it is far from clear that the benefits of this war will outweigh the harm which will be done" [23].

Bishop Anthony B. Taylor of Little Rock, Arkansas, issued a separate statement expressing "deep concerns that the necessary conditions for so-called 'just war' do not appear to be met" [24].

Vatican Secretary of State Cardinal Pietro Parolin went further still, declaring that the U.S.-Israeli war on Iran "does not meet the Catholic Church's criteria for a just war" — one of the most direct condemnations of a specific military action by a sitting Vatican official in recent memory [19].

Historical Precedent: John Paul II and Iraq

The closest historical parallel is John Paul II's opposition to the 2003 Iraq invasion. In his 2003 State of the World address, John Paul declared: "No to war! War is not always inevitable. It is always a defeat for humanity" [25].

The Vatican's diplomatic effort was aggressive. On Ash Wednesday 2003, Cardinal Pio Laghi hand-delivered a letter from the Pope to President George W. Bush at the White House. According to Laghi's later account, Bush set the letter aside, and the two engaged in a "pointed and sometimes heated debate." Laghi asked Bush: "Do you realize what you'll unleash inside Iraq by occupying it? The disorder, the conflicts between Shiites, Sunnis, and Kurds — everything that has in fact happened" [25].

Bush responded by dispatching Catholic scholar Michael Novak to Rome to argue the war's compatibility with just war doctrine. Novak held a two-hour symposium for 150 invited guests at the Vatican. The Pope did not budge [25].

The practical consequences were minimal. U.S.-Vatican diplomatic relations survived intact. No ambassador was recalled. Foreign aid was unaffected. The war proceeded [26].

The Steelman Case Against Papal Intervention

Critics of papal anti-war rhetoric — including some Catholic voices — have raised questions about consistency and effectiveness.

The Boston Globe published an opinion piece on March 28 examining what it called "a clash in the Catholic Church about the Iran war," noting that some Catholic intellectuals have argued a case for the conflict under just war principles [27]. Catholic World Report ran a piece headlined "A Cautious Case for the Iran War," though the specifics of its argument were not widely endorsed by the bishops [28].

A broader criticism concerns the Vatican's own record. Pope Francis, Leo's predecessor, drew fire from Ukrainian leaders in February 2024 for suggesting Kyiv should have "the courage of the white flag" to negotiate peace. Ukraine's then-foreign minister responded: "Our flag is a yellow and blue one. This is the flag by which we live, die, and prevail" [20]. Francis's December 2024 suggestion that Israel's actions in Gaza had "the characteristics of a genocide" prompted Israeli officials to accuse him of invoking antisemitic tropes [20].

The Vatican's institutional neutrality — designed to preserve its role as a diplomatic mediator — can look like selective moral outrage depending on the conflict. An academic paper published in the Journal of Religion, Conflict, and Peace examined "The Silence of the Roman Catholic Church on the Ukraine War," arguing that the Vatican's caution on naming Russia directly undermined its moral credibility [29].

Leo XIV faces the same tension. By refusing to name the United States, Israel, or Iran in his homily, he maintained the Vatican's diplomatic flexibility. But that same refusal allows defenders of the war to dismiss the homily as generic spiritual counsel rather than a specific moral judgment.

Catholics in the Crossfire

The war's impact on Catholic communities is direct, if numerically small. Iran is home to approximately 21,000 Catholics across Latin, Armenian, and Chaldean rites — a tiny fraction of the country's 87 million people [30]. In the Persian Gulf states hosting U.S. military assets, the Catholic population is far larger: an estimated 350,000 in Qatar, up to 400,000 in Kuwait, and nearly one million in the UAE, mostly migrant workers from the Philippines and India [30].

For these communities, the conflict has "tightened the boundaries within which these communities practice their faith, even as churches remain open and liturgies continue," as one report described it [30].

In the United States, where roughly 70 million people identify as Catholic — about 21% of the population — the war has produced internal division. Catholic politicians who support the administration's Iran policy face pressure from their bishops. Military chaplains serve in a chain of command whose civilian leadership describes the war in explicitly Christian terms [15][16].

The United States, as the world's fourth-largest Catholic country by population, is the most significant Catholic-majority-adjacent nation directly waging the conflict Leo addressed.

Francis's Shadow, Leo's Voice

Early headlines about the Palm Sunday homily — including the one that prompted this article — attributed the remarks to Pope Francis. Francis died on April 21, 2025, at age 88, after a long struggle with respiratory illness [31]. He was succeeded by Leo XIV after a conclave that concluded on May 8, 2025 [32].

The misattribution is telling. Francis spent 12 years building a public identity as a pope willing to confront powerful leaders — on immigration, climate, inequality, and war. His clashes with Trump, Netanyahu, Bolsonaro, Putin, and Milei became defining features of his papacy [20]. When people hear a pope rebuking warmakers, the reflex is still to think of Francis.

But Leo's intervention carries its own distinct weight. He chose the name Leo XIV in honor of Leo XIII, who developed modern Catholic social teaching during the upheaval of the Second Industrial Revolution [32]. He spent two decades in Peru before Francis brought him to the Vatican [32]. And he is, inescapably, an American citizen presiding over a church in which roughly 70 million of his compatriots are communicants of the very nation whose war he appears to condemn.

Francis, in his final years, used high-visibility moments — Christmas, Easter, the Angelus — to cement his legacy on war and peace. John Paul II did the same as his health declined before his death in 2005, making his Iraq opposition one of the defining stands of his late papacy [25][31].

Leo is 70. He is not dying. His Palm Sunday homily was not a valedictory statement but an opening position — delivered less than a year into a pontificate that, if history is any guide, could last decades.

What Happens Next

The White House has not issued a formal response to the homily. No named U.S. official has addressed Leo's remarks directly [1]. The State Department has maintained its standard position that the U.S. values its diplomatic relationship with the Holy See.

Diplomatic historians note that papal moral condemnations rarely alter the course of conflicts in the short term. John Paul II's opposition to the Iraq war did not prevent it. Francis's repeated calls for peace in Ukraine did not end it. The Vatican's power is not coercive but reputational — the ability to frame a conflict in moral terms that persist long after the fighting stops [25][26].

The question is not whether Leo's words will stop the bombing of Iran. The question is whether, years from now, they will be remembered the way John Paul's "No to war!" is remembered — as a marker of where the world's largest Christian institution stood when its own country went to war.
