Pope Leo XIV has criticized attempts to justify war on religious or moral grounds, arguing that the traditional concept of a "just war" has lost its relevance in today's world and reiterating the need for peace and dialogue in resolving international conflicts.

Speaking at Barcelona's Sagrada Família, the head of the Vatican reflected on the human cost of war and the responsibilities of religious communities in times of conflict.

"We cannot believe in Jesus and at the same time promote war. We cannot believe in Jesus and accept the killing of innocent people," the Pope said, rejecting efforts to defend armed conflict through moral or religious arguments.

The pontiff renewed his call for peace, emphasizing that human life and dignity must remain at the center of international efforts to address crises and disputes.

Addressing migration, Pope Leo XIV also urged greater solidarity with people forced to flee their homes because of poverty, war and instability. He said societies should not turn their backs on those seeking safety and a chance to rebuild their lives.

The Pope stressed that Christians have a moral responsibility to support and assist those escaping hardship and conflict, highlighting compassion and human solidarity as core values of the faith.

The remarks were delivered before thousands of attendees during a ceremony that was also attended by King Felipe VI and Queen Letizia.

Pope Leo XIV has repeatedly advocated diplomatic solutions to international crises, including conflicts in the Middle East, arguing that dialogue and negotiation should take precedence over military action.

His latest comments reflect the Vatican's longstanding position that lasting peace can only be achieved through diplomacy, reconciliation and respect for human dignity. (ILKHA)
