Striking a tone sharper than any he has used since taking office, Pope Leo on Sunday condemned war as incompatible with Christian faith, telling a vast crowd gathered in St. Peter’s Square that leaders who take up arms cannot expect God to hear them.
“[Jesus] 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,'” the pontiff declared, quoting a biblical passage before tens of thousands of worshippers assembled for Palm Sunday — the liturgical opening of Holy Week ahead of Easter.
The remarks arrived as the conflict with Iran entered its second month, and they carry particular weight given the pope’s reputation for deliberate, measured language. Leo, the first American to hold the papacy, has in recent weeks grown increasingly vocal about the war, repeatedly demanding an immediate ceasefire and stating earlier this week that aerial bombardments are indiscriminate and ought to be prohibited.
No heads of state were named. But the timing was difficult to ignore. The war traces back to joint US-Israeli airstrikes launched on February 28, and some American officials have reached for religious framing to characterize that military action. Defense Secretary Pete Hegseth, who has introduced Christian prayer services at the Pentagon, led a service Wednesday in which he prayed for “overwhelming violence of action against those who deserve no mercy.”
Leo anchored his address in a moment from the Gospels — the scene in which Jesus, on the night of his arrest, stopped a follower who had drawn a sword against those coming to seize him.
“This is our God: Jesus, King of Peace, who rejects war, whom no one can use to justify war,” Leo told the crowd under bright sunshine. “[Jesus] did not arm himself, or defend himself, or fight any war. He revealed the gentle face of God, who always rejects violence. Rather than saving himself, he allowed himself to be nailed to the cross.”
The position staked out Sunday puts the Vatican in direct tension with officials who have publicly framed military force in Christian terms — a conflict of religious authority that shows no sign of easing while the war continues.
