Pope Leo XIV Calls for Peace Amid U.S.–Iran Tensions, Warns “War Is Not Holy”

Pope Leo XIV issued a strong appeal for peace from the Vatican on Sunday, warning against framing armed conflict in religious terms amid escalating tensions between the United States and Iran.

icago-born pontiff — the first American to lead the Catholic Church — said during his remarks that war should never be considered sacred.

“War is not holy; only peace is holy because it is willed by God,” the pope said, repeating the phrase several times as part of a broader call for global de-escalation.

His comments came shortly after a group of evangelical Christian leaders gathered in the Oval Office with U.S. President Donald Trump, where they prayed over the president during discussions about the ongoing conflict with Iran. Some supporters of the administration have framed the confrontation in religious or biblical terms, a narrative the pope appeared to challenge.

During his address, the pontiff described the human cost of war and warned that continued escalation could bring wider regional and global consequences.

“If the world is deaf to this appeal, we are certain that God will hear our prayer and the lament of so much suffering,” he said.

The pope also urged religious leaders around the world to advocate for peace and to speak on behalf of civilians affected by conflict, including the poor, displaced communities, and others caught in war zones.

“We must dare peace,” he said. “Enough of wars with their painful piles of death, their destruction and displacement.”

The remarks come as international concern grows over the expanding conflict and the potential for further escalation in the Middle East. Religious leaders across different traditions have increasingly weighed in on the moral implications of the fighting and the humanitarian impact on civilians.

The White House has not issued an immediate response to the pope’s comments.

Trump Says U.S. Had No Advance Knowledge of Israeli Strike on Iran’s ‘Extremely Valuable’ South Pars Gas Field
Trump Says U.S. Had No Advance Knowledge of Israeli Strike on Iran’s ‘Extremely Valuable’ South Pars Gas Field U.S. President Donald Trump said Washington had no prior knowledge of an Israeli strike on Iran’s South Pars gas field, while asserting that no further attacks on the site would take place. In a post on March 18, Trump said Israel had carried out a strike targeting South Pars Gas Field—the world’s largest natural gas field located offshore in Iran’s southern Bushehr province—but added that only a small portion of the facility was hit. According to Trump, the United States was not informed in advance of the operation. He also stressed that Qatar “was not involved in any way” and had no foreknowledge of the strike.

The U.S. president said that due to a lack of clarity about the incident and its details, Iran responded with what he described as an “unreasonable and unjust” attack on part of Qatar’s liquefied natural gas (LNG) infrastructure. Trump said Israel would not conduct any further strikes on South Pars unless Iran continues attacking Qatar, which he described as “completely innocent” in the situation. “Israel will not carry out any additional attacks related to this extremely important and valuable South Pars gas field unless Iran continues to strike Qatar—a country entirely uninvolved in this matter,” Trump wrote. He warned that if Iran persists in targeting Qatar, the United States would “destroy the entire South Pars gas field” with a level of force Iran “has never seen before.” At the same time, Trump said he does not wish to authorize such a level of violence due to the long-term consequences it could have for Iran’s future. “However, if Qatar’s LNG facilities continue to be attacked, I will not hesitate to act,” he added. Iran has not publicly commented on Trump’s statements. Earlier, Iranian state media reported that natural gas facilities linked to South Pars had come under attack. The Times of Israel also cited Israeli officials as saying the country’s air force conducted strikes on the gas infrastructure on March 18. Shortly afterward, Iran’s Islamic Revolutionary Guard Corps (IRGC) threatened to target oil and gas infrastructure in Qatar, Saudi Arabia, and the United Arab Emirates, raising concerns about potential disruptions to regional energy supplies. Later on March 18 (local time), Qatari authorities reported a fire at the Ras Laffan Industrial City gas facility following what was described as an Iranian ballistic missile attack. Qatar’s Interior Ministry later said the fire had been brought under control.
