This piece in the WSJ (gift link)lays out the history of the church and the US government and as we know it was often hostile mostly due to anti Catholic bigotry. But it changed :
Post-Cold War presidents mostly walked in lockstep with Catholic leaders at home and in Rome, with a major exception being the Iraq war. John Paul II advised George W. Bush not to take pre-emptive action against Saddam Hussein. Bush stayed the course but reaffirmed his respect for the holy father. The next year Bush presented the pope with the Presidential Medal of Freedom, vowing to work with the pope “for human liberty and human dignity, in order to spread peace and compassion.”
Trump has chosen a different path.
In each election since 2016, Trump won a majority of the White Catholic vote, increasing his percentage in 2024 to about 60%. Yet beneath these positive election results, the mood can be tense. Many of the president’s actions suggest values that are out of step with the presidents that came before him; and as recent popes have demonstrated, they are also out of line with the values of the Catholic church.
During Trump’s first presidential campaign and first term, Pope Francis noted that the gospel called on Christians to build bridges, not (border) walls. Trump issued a statement that Francis was going to wish Trump was president if ISIS attacked the Vatican.
But the real escalation of the conflict has come in recent months. Pope Leo XIV, the first American pontiff, has proven to be very politically savvy. He seems to have ensured that when he speaks, the American bishops generally fall in line behind him. He has called on the bishops to defend the rights and dignity of immigrants and refugees, and they have answered by submitting legal briefs to the Supreme Court on their behalf.
Their larger clash, however, came over the war in Iran. When Trump vowed to destroy Iranian civilization, to blast it back to the stone ages, Leo called his rhetoric “unacceptable.” He preached against the “delusion of omnipotence,” and called for an end to “idolatry of self and money” and “enough of war.”
Catholics have criteria that they invoke to evaluate righteousness of wars, which date to the fifth century teachings of St. Augustine. They determine whether a cause is just, if all other options have been exhausted, if war will lead to peace, and if the evil being targeted by war is greater than the evil of the violence the war will inflict. This allows them to determine what is a “just war” and what is not.
The American president and his advisers have made limited effort to justify their aggressive military actions, which also meet none of the traditional Catholic just war criteria.
The pope’s skepticism about the administration’s rationale for war prompted Trump, unlike any president in the last 100 years, to recast the Vatican as an adversary rather than an ally. Never before, even at the height of U.S. anti-Catholicism, has a sitting president attacked the pope like this
He attacks anyone who dares to disagree with him or is more popular. I honestly don’t think it’s any more complicated than that. He’s a Know-Nothing in the original sense of the world taking the country back to the 1800s in more ways than one.
