VATICAN CITY: Pope Leo on Saturday urged world leaders to end what he called the “madness of war,” in an impassioned appeal as senior US and Iranian officials met in Pakistan to discuss ending the six-week conflict.

At a special prayer vigil in St. Peter’s Basilica, the first US pope decried the use of religious language to justify war and said a “delusion of omnipotence that surrounds us ... is becoming increasingly unpredictable”.

Making a direct appeal to world leaders, he said: “Stop! It is time for peace! Sit at the table of dialogue and mediation, not at the table where rearmament is planned.” Leo, who is known for choosing his words carefully, has emerged as an outspoken critic of the Iran war.

On Saturday, he used forceful language to denounce conflict, citing letters from children in war zones he said described “horror and inhumanity”. The pope also referenced the Church’s opposition to the 2003 US-led invasion of Iraq, citing an appeal by the late Pope John Paul II made four days before the start of that conflict.

“Enough of the idolatry of self and money!” Leo said. “Enough of the display of power! Enough of war!”

The pope, who on March 30 said God rejects the prayers of leaders who start wars and have “hands full of blood,” denounced again on Saturday the use of Christian language to justify war.

“The balance within the human family has been severely destabilised,” said Leo.
