The intersection of faith and firepower has long been a volatile space in American diplomacy, but the current rhetoric emanating from the Pentagon is pushing that tension to a breaking point. US Defense Secretary Pete Hegseth, an evangelical Christian, has increasingly woven religious imperatives into the strategic narrative of the ongoing war with Iran, sparking a wave of backlash across Western capitals and an explicit, if unnamed, rebuke from the Vatican.
The controversy intensified approximately three weeks ago when Hegseth called upon the American public to kneel in daily prayer, specifically seeking military victory “in the name of Jesus Christ.” For critics, the appeal transcends personal piety, representing a shift toward a “crusader” mentality in the management of US national security. For the Pentagon, We see a reflection of the Secretary’s personal convictions—a common trait among many in the American leadership.
The friction has now reached the highest levels of the Catholic Church. Speaking at St. John Lateran Basilica ahead of Easter, Pope Leo XIV addressed the dangers of conflating divine will with political ambition. While the Pope did not mention Hegseth by name, his message was pointed, warning that the Christian mission is frequently distorted by a “desire for domination, completely at odds with the way of Jesus.”
A Theological Divide Over Domination
Pope Leo XIV, the first pontiff born in North America, has spent much of his early papacy navigating a delicate relationship with the Trump administration. According to reports from the New York Times, the Pope initially sought to avoid direct confrontation with the White House, preferring indirect influence—such as encouraging US bishops to advocate for migrants facing deportation policies.
However, the escalation of the conflict with Tehran appears to have shifted the Pope’s calculus. In a late March sermon, Leo XIV suggested that the nature of divine mercy is incompatible with the machinery of war, stating that Jesus “does not heed the prayers of those who wage war, but rejects them.”
In his most recent address, the Pope urged a return to dialogue between Washington and Tehran, framing the pursuit of power as a spiritual failure. “We tend to see ourselves as powerful when we dominate,” the Pope said. “God has given us an example — not how to rule, but how to liberate; not how to destroy life, but how to give it.”
The Ideology of the ‘American Crusade’
To understand the US defense chief’s religious rhetoric, one must look to the ideological framework Hegseth has championed long before taking office. His convictions are not merely private; they are etched into his skin and printed in his writing. Hegseth bears a Jerusalem cross on his chest and the phrase “Deus Vult”—the Latin battle cry of the First Crusade meaning “God wills it”—on his arm.
In his 2020 book, American Crusade, Hegseth challenged the foundational legal structures of the US government, describing the separation of church and state as a “left-wing myth.” He has frequently argued that the United States “remains a Christian nation in its DNA, if You can preserve it,” suggesting that the country’s success and security are inextricably linked to its adherence to Christian values.
This worldview transforms a geopolitical conflict into a spiritual one. Reports from The Independent indicate that Hegseth views the war with Iran not as a standard political or territorial dispute, but as a cosmic struggle between excellent and evil. In this framework, military hardware and strategic operations are viewed not just as tools of statecraft, but as instruments of divine will.
Legal and Strategic Implications
Military legal experts and historians have warned that framing a modern war in these terms carries significant risks. The primary concern is that “cosmic” rhetoric removes the possibility of diplomatic compromise, as one does not negotiate with “evil.”
the rhetoric has created internal friction within the US military. Michael Weinstein, founder and president of the Military Religious Freedom Foundation, argues that the Secretary is alienating the diverse population of non-Christian service members who swear an oath to the Constitution, not a specific faith.
“He is making it clear that this is Jesus versus Muhammad — this is unprecedented,” Weinstein said.
Beyond internal morale, analysts warn that this language may inadvertently embolden the fundamentalist elements of the Iranian regime, providing them with a narrative of religious persecution that could harden their resolve and escalate the severity of the conflict.
The Pentagon’s Defense
The Department of Defense has pushed back against the notion that the Secretary’s faith is inappropriate for his role. Pentagon spokesperson Kingsley Wilson defended Hegseth, stating that he is a “proud Christian,” a characteristic shared by millions of Americans and several of the nation’s most revered historical figures.
Wilson noted that leaders such as George Washington and Franklin D. Roosevelt frequently expressed their faith through prayer for their troops. The Pentagon maintains that calling for the public to pray for service members is a standard American tradition and is not inherently controversial.
| Perspective | View on Religious Rhetoric | Primary Concern |
|---|---|---|
| Secretary Hegseth | Faith is a source of strength and divine guidance. | Preserving the “Christian DNA” of the US. |
| Pope Leo XIV | Faith should lead to liberation, not domination. | The distortion of the Christian mission for power. |
| Legal Experts | Rhetoric undermines church-state separation. | Escalation of conflict and alienation of troops. |
As the conflict with Iran continues, the tension between the Pentagon’s “cosmic” framing and the Vatican’s call for peace remains unresolved. The next key indicator of this friction will be the administration’s response to the Pope’s Easter directives, which are expected to call for a formal ceasefire and a renewed diplomatic channel with Tehran.
