US Secretary of State Marco Rubio, Pope Leo XIV discuss Iran war at Vatican meeting

(OSV News) — U.S. Secretary of State Marco Rubio met with Pope Leo XIV at the Vatican on May 7, discussing the war in Iran, humanitarian aid and what the Vatican described as “the need to work tirelessly to promote peace,” amid ongoing tension between President Donald Trump and the pope.

Rubio, who is Catholic, spoke with the American pope for over 45 minutes in a private meeting in the Apostolic Palace before also sitting down with Cardinal Pietro Parolin, the Vatican secretary of state, and Archbishop Paul Gallagher, the Vatican’s foreign minister, for talks that reaffirmed “the shared commitment to fostering good bilateral relations between the Holy See and the United States of America,” according to the Vatican.

“There was then an exchange of views on the regional and international situation, with particular attention to countries affected by war, political tensions and difficult humanitarian situations, as well as the need to work tirelessly to promote peace,” the Holy See Press Office said in a statement released after the meeting.

Secretary Rubio wrote on social media that he met the pope “to underscore our shared commitment to promoting peace and human dignity.”

In a separate statement, the State Department said Rubio’s meeting with Cardinal Parolin covered mutual cooperation and pressing international issues, including humanitarian efforts in the Western Hemisphere and efforts to achieve a durable peace in the Middle East. Rubio also welcomed the recent arrival of Archbishop Gabriele Caccia as the new apostolic nuncio to the United States.

It was Rubio’s second substantive meeting with Pope Leo. On May 19, 2025, the day after the pope’s inauguration Mass, Rubio and Vice President JD Vance also held a bilateral meeting with the pope, according to Vatican News.

On the eve of the May 7 audience, Cardinal Parolin told journalists that the U.S. government had requested the meeting and that the pope remained open to continued dialogue with Washington.

“We cannot ignore the United States,” Cardinal Parolin said. “Despite some difficulties, they certainly remain a key partner for the Holy See, not least because they play a role in almost every situation we face today.”

Cardinal Parolin said that he was expecting to discuss “themes of international politics and above all conflicts,” including issues in Latin America and Cuba — “all those that are the most pressing issues.” On Iran, he said the Holy See would offer no new proposals beyond its longstanding call for dialogue.

“These conflicts,” he said, “cannot be resolved by force, but must be addressed and resolved through negotiation,” adding, “Let it be a negotiation of good will, sincere, so that all parties can express their point of view and find points of convergence.”

The visit of the U.S. secretary of state comes days after Trump reignited tensions by repeating his claim that the pope “thinks it’s just fine for Iran to have a nuclear weapon” in an interview that aired May 5, an assertion that Pope Leo swiftly rejected.

“If anyone wishes to criticize me for proclaiming the Gospel, let them do so with the truth,” Pope Leo told journalists outside Castel Gandolfo that evening.

“The Church has spoken out for years against all nuclear weapons, so there is no doubt about this,” the pope added. “I simply hope to be heard for the sake of the Word of God.”

Cardinal Parolin weighed in on recent public clashes between Pope Leo and Trump, calling the president’s repeated attacks on the pope “a bit strange to me, to say the least.”

At a White House briefing the same day, Rubio disputed suggestions that his Vatican visit was an attempt to “smooth things over with the pope,” saying the two sides have “shared concerns” including religious freedom in Africa and the distribution of humanitarian aid to Cuba.

“We gave Cuba $6 million of humanitarian aid, but obviously, they won’t let us distribute it,” said Rubio, who is the son of Cuban immigrants. “We distribute it through the Church. We’d like to do more. We’re willing to give more humanitarian aid to Cuba, by the way, distributed through the Church, but the Cuban regime has to allow us to do it.”

On the question of a possible phone call between Trump and Pope Leo, Cardinal Parolin said May 6 it was “premature” to say whether one would take place, but indicated the pope would be receptive.

“The Holy Father is open to all options,” Cardinal Parolin said. “If there were an offer or a request for a direct dialogue with President Trump, I imagine that he would have no difficulty in accepting it.”

The meeting with Rubio was one of several audiences on the pope’s schedule that day. Pope Leo also met with Polish Prime Minister Donald Tusk, bishops from Burkina Faso and Niger, German Cardinal Reinhard Marx, and members of the Pontifical Swiss Guard.

Rubio is scheduled to meet Italian Prime Minister Giorgia Meloni and Foreign Minister Antonio Tajani on May 8.
