April 5 (UPI) — Pope Leo XIV on Sunday beseeched world leaders to “lay down” the weapons of war and use “dialogue” rather than force as the means to bring about peace.

In the annual Urbi et Orbi address delivered by the presiding Catholic pontiff each Easter Sunday in St. Peter’s Square at the Vatican, Leo said the holy day can provide a light from Christ allowing hearts “to be transformed by his immense love for us.

“Let those who have weapons lay them down. Let those who have the power to unleash wars choose peace. Not a peace imposed by force, but through dialogue. Not with the desire to dominate others, but to encounter them,” Leo said in his first Easter address as pontiff.

An estimated 50,000 people jammed the Roman square to hear Leo’s Urbi et Orbi Easter Mass homily, or “To the City and the World,” in which he warned against allowing “indifference” to blunt the impact of war’s devastation as conflicts raged in Iran, Lebanon, Gaza, Ukraine and elsewhere in the world.

“We are growing accustomed to violence, resigning ourselves to it, and becoming indifferent,” he said. “Indifferent to the deaths of thousands of people. Indifferent to the repercussions of hatred and division that conflicts sow. Indifferent to the economic and social consequences they produce, which we all feel.”

Instead, he declared, “We cannot continue to be indifferent! And we cannot resign ourselves to evil!”

Leo, the first American pope, has been a frequent critic of U.S. President Donald Trump, but did not specifically mention him or any other leader or country during the Easter homily. Rather, he anti-war remarks were universal.

“On this day of celebration, let us abandon every desire for conflict, domination, and power, and implore the Lord to grant his peace to a world ravaged by wars and marked by a hatred and indifference that make us feel powerless in the face of evil,” Leo urged.

In his time as pope, Leo has established a track record of issuing unambiguous calls for peace.

Last month, for instance, he voiced a direct demand for an end to the U.S.-Israeli war in Iran as the conflict entered its third week.

“On behalf of the Christians of the Middle East, and of all women and men of good will, I appeal to those responsible for this conflict: Cease fire!,” the pope said during the Angelus in St. Peter’s Square on March 15.
