Pope Leo XIV used his Sunday Angelus address at St Peter’s Square on 8 March to issue his second consecutive weekly appeal for peace in Iran and the wider Middle East, warning that the escalating conflict risked drawing other nations into the conflagration and expressing particular fear that Lebanon — a country he has described with affection — could once again sink into instability as the war entered its ninth day. Speaking before approximately 15,000 pilgrims gathered in the square, the American-born pontiff said deeply disturbing news continued to arrive from Iran and across the region, describing a widening climate of hatred and fear that he argued no military campaign could resolve. He called on all parties to open space for dialogue in which the voices of peoples, not weapons, could be heard — an appeal that carried the weight of the Holy See’s longstanding insistence on diplomatic solutions to conflicts that draw in civilian populations.
The Pope’s remarks on 8 March echoed and deepened the intervention he had made exactly one week earlier, on 1 March, the day the US-Israeli air campaign against Iran began in earnest and news broke of the killing of Supreme Leader Ayatollah Ali Khamenei. On that occasion Leo warned of “a tragedy of enormous proportions” and called on all parties to “assume the moral responsibility of halting the spiral of violence before it becomes an irreparable abyss.” He had stressed that stability and peace were not built through mutual threats or weapons that sow destruction, pain, and death, but only through reasonable, authentic, and responsible dialogue — a formulation the Vatican returned to consistently across the nine days of the conflict. The Vatican’s top diplomat, Cardinal Pietro Parolin, separately criticised the strikes, warning that the sidelining of international law and embrace of preventive war doctrine risked igniting an even broader conflict.
The Pope’s concern for Lebanon is rooted in both recent history and personal engagement — he visited the country during the papacy and has maintained close attention to its fragile recovery from the 2006 war and the devastation of the 2020 Beirut port explosion. By 7 March, Israel had ordered almost half a million people to leave southern Lebanon and southern Beirut as it sought to eliminate Hezbollah positions in the country, and Lebanon’s social affairs minister had confirmed that approximately 454,000 Lebanese had registered as displaced. The prospect of a full-scale Israeli ground operation in Lebanon simultaneous with the air campaign against Iran represents precisely the kind of multi-front escalation the pontiff was warning against — a scenario in which the original bilateral conflict between the United States, Israel, and Iran consumes an entire regional order built on fragile ceasefires and exhausted populations.
The Iran war presents the first major international crisis of Leo XIV’s papacy, and his approach has been carefully calibrated: expressing clear moral concern about civilian suffering and the logic of military escalation without assigning blame in terms that would foreclose the Vatican’s role as a potential diplomatic interlocutor. His repeated emphasis on dialogue and his explicit framing of the conflict as a threat to peoples rather than states reflects a consistent papal tradition of speaking to the human cost of war rather than its geopolitical mechanics. With Trump demanding unconditional Iranian surrender and Tehran vowing never to yield, the space for the kind of dialogue the Pope is calling for appears vanishingly narrow — but the Holy See’s voice carries moral authority that no military communiqué can replicate, and Leo’s persistence in raising it weekly ensures it remains part of the global conversation about what comes next.
