"This is our God: Jesus, King of Peace, who rejects war, whom no one can use to justify war."

Pope Leo XIV used his Palm Sunday sermon to take what appears to be a shot at US Defense Secretary Pete Hegseth.

In his sermon, excerpts of which he published on social media, the pope emphasized Christian teachings against violence while criticizing anyone who would invoke Jesus Christ to justify a war.

"This is our God: Jesus, King of Peace, who rejects war, whom no one can use to justify war," Pope Leo said. "He does not listen to the prayers of those who wage war, but rejects them."

The pope also encouraged followers to "raise our prayers to the Prince of Peace so that he may support people wounded by war and open concrete paths of reconciliation and peace."

While speaking at the Pentagon last week, Hegseth directly invoked Jesus when discussing the Trump administration's unprovoked and unconstitutional war with Iran.

Specifically, Hegseth offered up a prayer in which he asked God to give US soldiers "wisdom in every decision, endurance for the trial ahead, unbreakable unity, and overwhelming violence of action against those who deserve no mercy," adding that "we ask these things with bold confidence in the mighty and powerful name of Jesus Christ."

Mother Jones contributing writer Alex Nguyen described the pope's sermon as a "rebuke" of Hegseth, whom he noted "has been open about his support for a Christian crusade" in the Middle East.

Pope Leo is not the only Catholic leader speaking against using Christian faith to justify wars of aggression. Two weeks ago, Cardinal Pierbattista Pizzaballa, the Latin patriarch of Jerusalem, said "the abuse and manipulation of God’s name to justify this and any other war is the gravest sin we can commit at this time."

“War is first and foremost political and has very material interests, like most wars," Cardinal Pizzaballa added.
