Pope Leo XIV told reporters Monday he would not be deterred by President Trump's weekend broadside against his opposition to the Iran war, opening an 11-day tour of Africa as the breach between the Vatican and the White House widened into the most public rupture between a sitting U.S. president and a pope in modern memory.
The clash raises the stakes for Trump at home, where more than 70 million Americans identify as Catholic, roughly 20 percent of the population, and abroad, where allies including Italian Prime Minister Giorgia Meloni have begun distancing themselves from his language. It also tests whether the first American-born pontiff, elected last year, will set the tone for a church willing to challenge Washington directly on the Middle East.
The lede exchange
Trump opened the dispute Sunday night with a series of posts on Truth Social responding to a peace vigil the pope led Saturday at St. Peter's Basilica, where Leo warned against a "delusion of omnipotence" driving global instability. The president called the pontiff weak on crime and foreign policy and wrote, "I don't want a Pope who thinks it's OK for Iran to have a Nuclear Weapon."
In a separate post, Trump suggested the conclave had chosen Leo to manage him: "If I wasn't in the White House, Leo wouldn't be in the Vatican." He later shared, and then deleted, an AI-generated image depicting himself as Jesus Christ laying hands on a bedridden man, surrounded by eagles and an American flag.
The pope's reply
Speaking to reporters aboard his plane to Algiers, Leo declined to engage the president directly but said he would keep pressing the case against the war. "I have no fear of the Trump administration, or speaking out loudly of the message of the gospel, which is what I believe I am here to do, what the Church is here to do," he said.
The pontiff added: "Too many people are suffering in the world today. Too many innocent people are being killed. And I think someone has to stand up and say there's a better way."
He has called Trump's earlier threat to destroy Iranian civilization "unacceptable" and has urged the administration to find an "off-ramp" to end the conflict.
On the Hill
Three American cardinals broke with the administration in a joint appearance on "60 Minutes" Sunday night. "In Catholic teaching, this is not a just war," Cardinal Robert McElroy, the archbishop of Washington, told the program. "This is a war of choice." Bishop Robert Barron, a prominent conservative voice in the U.S. church, called Trump's posts "entirely inappropriate and disrespectful" and said the president "owes the pope an apology."
Archbishop Paul Coakley, head of the U.S. Conference of Catholic Bishops, said Leo is not a politician but "the vicar of Christ."
Rome weighs in
Meloni, a Catholic who leads a right-wing coalition and has been among Trump's closest European allies, issued a statement Monday calling his remarks unacceptable. "The Pope is the head of the Catholic Church, and it is right and normal for him to call for peace and to condemn every form of war," she said. Her coalition partner Matteo Salvini, leader of the League party, said that "attacking the Pope... doesn't seem like a useful or intelligent thing to do."
A Vatican spokesman, Father Antonio Spadaro of the Dicastery of Culture and Education, wrote that Trump's posts reflected his "impotence" in the face of the church's criticism. Iranian President Masoud Pezeshkian also condemned what he called an insult to the pontiff.
The counterpoint
Trump showed no sign of retreat. Asked Monday whether he would apologize, he refused, describing Leo as "a very liberal person" who "doesn't believe we should be toying with a country that wants a nuclear weapon so they can blow up the world." Vice President JD Vance, a Catholic, has not publicly commented. Meloni waited more than a day to respond, and Italian opposition parties accused her of hesitating to defend the pontiff.
The pope's Africa itinerary runs through next week, with stops in Algeria, Angola, Equatorial Guinea and Cameroon before his return to Rome.
