This did not start with a tweet. According to Vatican officials, this feud began in January when Pentagon representatives met with the Holy See and appeared to seek something no American administration had ever asked for before. Not political alignment. Moral endorsement of war. One Pentagon official allegedly referenced the Avignon Papacy, the 14th century period when the French Crown imposed its will on the Catholic Church, as a cautionary tale of what could happen if the Vatican did not cooperate. The Vatican left that meeting believing the United States was asking for its blessing on a war it had already decided to fight. The Trump administration called the meeting respectful and reasonable. Rome called it something else entirely.
It went public in early April. First, three US cardinals appeared on CBS 60 Minutes and declared the Iran war not a just war under Catholic teaching. That alone was extraordinary. Then Trump got on Truth Social. He called Pope Leo XIV “WEAK on Crime, and terrible for Foreign Policy.” He said he did not want a pope who thought it was terrible that America attacked Venezuela or who criticised the president of the United States. For the record, the pope had never said it was acceptable for Iran to have a nuclear weapon, which Trump also claimed. None of that stopped the post from spreading everywhere.
Then Trump posted an AI-generated image of himself depicted as a Christ-like figure, surrounded by American flags and eagles, appearing to heal a sick person. It was deleted by the afternoon. His explanation was that he thought it showed him as a doctor. A doctor. The president of the United States posted a messianic image of himself during an active war and then said he thought it was a medical illustration.
Pope Leo XIV spent eleven days crossing four African countries calling for an end to the wars. He warned against invoking the name of Jesus for battle, calling it distorted by a desire for domination entirely foreign to the way of Jesus Christ. He pointed the finger directly at Trump. You started this war. You have the power to end it. When reporters asked about the feud on the papal plane he said it was not in his interest to debate the president. Then he added, calmly, that he had no fear of the Trump administration.
“I have a right to disagree with the pope,” Trump said.
What makes this different from any previous tension between a US president and the Vatican is the pope himself. Leo is the first American pope, born Robert Prevost, raised in Chicago, with family roots in the Creole communities of New Orleans. He spent decades in Peru as a missionary. He speaks fluent culturally attuned English with no need for translation, which means every word lands directly in the American media ecosystem with full force. Previous popes relied on translation, giving Vatican officials room to soften remarks after they caused controversy. That buffer is completely gone now. Leo says exactly what he means and the news cycle picks it up before Rome can even think about damage control.
The political fallout is where this gets really serious. Roughly 20 percent of Americans identify as Catholic, concentrated heavily in battleground states. In 2024, nearly six in ten Catholic voters backed Trump. That coalition is fracturing. Among Latino voters, a group that swung significantly toward the GOP in 2024, Trump’s approval has fallen to 30.7 percent with 66.7 percent disapproval. Democrats are currently favoured to win the House in 2026. Republican strategists know exactly what those numbers mean. Most of them are staying quiet about it.
The pope has not visited the United States since his election at the conclave in May 2025 and has no plans to do so this year. Trump has not apologised. The Vatican has not softened. And somewhere in Rome, officials are sitting with the quiet confidence of an institution that has been navigating power for two thousand years. They have seen emperors. They have seen kings. They are not particularly worried about this one.
