President Donald Trump and his advisers forget that America was not founded as a Christian nation, a former aide to a different Republican president warned on Tuesday.
“The separation of church and state is foundational to American civilization,” Steve Schmidt, who advised President George W. Bush, said on his Substack. “In fact, on the list of the greatest American inventions, the two at the top — competing for gold and silver — are the peaceful transition of power and the separation of church and state. These are brilliant ideas, the greatest in all of history.”
Yet according to Schmidt, Trump is violating this separation in dangerous and deliberate ways. Specifically, he called out Secretary of Defense Pete Hegseth and Press Secretary Karoline Leavitt for explicitly citing “our Lord and Savior, Jesus Christ” when justifying America’s recent invasion of Iran.
“Do you see all the Stars of David in the Normandy cemetery?” Schmidt said. “World War II was not a Christian mission. The United States Army is not a Christian organization. In America, we have a right to freedom of conscience, freedom of religion, and freedom of speech — and all of it is under threat from Donald Trump and his administration.”
Ultimately, Schmidt refused to classify America’s war in Iran as being motivated by any form of respectable Christianity.
“This is not religion,” Schmidt said. “This is a scam. This is a con.”
Schmidt is not alone in critiquing the Trumpist version of Christianity. Religious studies scholar Sarah Posner recently spoke with The Daily Beast's Greg Sargent about Pope Leo XIV, the American-born Pope who denounced warmongering interpretations of Christianity in a speech delivered shortly after Hegseth's breakfast prayer.
"Hegseth is expressing an extreme version of Christian supremacy, where America, a Christian nation, is entitled, and in fact probably, in his mind, required by God, to smite America's enemies — or to smite the enemies of Christianity, even, Posner said. "When we talk about Christian nationalism, this is exactly what we're talking about. But the important thing to remember with Hegseth, in contrast to other versions of Christian nationalism that we see more commonly in the Republican Party, is that his is a very extreme version of Christian supremacy where we Christians are entitled to go out and take dominion over the world, to vanquish enemies, and to do so violently — and even when they do so violently, with the express mandate from God."
Speaking with this journalist for Salon in 2024 about historian Federico Finchelstein comparing Trump’s far right “rhetorical violence” to that of Nazi German dictator Adolf Hitler, Leavitt replied that “it's been less 72 hours since the second assassination attempt on President Trump's life and the media is already back to comparing President Trump to Hitler. It's disgusting. This is why Americans have zero trust in the liberal mainstream media."
As Schmidt pointed out, America was founded as an explicitly secular country. The First Amendment to the Constitution states that “Congress shall make no law respecting an establishment of religion, or prohibiting the free exercise thereof,” while President Thomas Jefferson — who also co-authored the Declaration of Independence — wrote in 1802 that “religion is a matter which lies solely between Man & his God” and as such “the legitimate powers of government reach actions only, & not opinions” because the American people “declared that their legislature should ‘make no law respecting an establishment of religion, or prohibiting the free exercise thereof,’ thus building a wall of separation between Church & State.”
