Mary Miller is introducing new legislation that would require every federal building in America to prominently display the nation’s motto: “In God We Trust.”

The Republican congresswoman from Illinois unveiled the “In God We Trust Act” on Thursday, saying the measure is intended to reaffirm America’s spiritual heritage as the country approaches its 250th anniversary.

“For nearly 70 years, our national motto, ‘In God We Trust,’ has served as a declaration of faith that has guided our nation,” Miller told The Christian Post. “We will never apologize for being one nation that places its trust in Almighty God.”

If passed, the bill would direct the General Services Administration to inscribe or visibly display the motto in all public federal buildings nationwide.

The phrase “In God We Trust” first appeared on U.S. coins in 1864 during the Civil War, when leaders sought to acknowledge God and encourage national unity during one of the darkest periods in American history. In 1956, during the Cold War, Congress unanimously adopted it as the nation’s official motto under President Dwight D. Eisenhower, contrasting America’s religious identity with the Soviet Union’s atheistic ideology.

Miller, who has openly shared her Christian testimony and describes herself as a born-again believer, has consistently advocated for policies rooted in biblical values. A Sunday school teacher and homeschool mother, she also helped establish the Congressional Family Caucus in 2023 to defend what she describes as the traditional nuclear family.

The legislation comes just days before “Rededicate 250,” a large Christian gathering planned for the National Mall in Washington. The event is expected to feature worship, prayer, Scripture readings, testimonies, and a public rededication of the nation to God.

Miller’s proposal is also the House companion bill to similar legislation introduced in the Senate last year by Josh Hawley. Hawley has repeatedly warned that America is facing what he calls a growing “spiritual crisis” tied to the nation’s rejection of its Christian roots.

Speaking recently at The Southern Baptist Theological Seminary, Hawley argued that America’s moral and cultural struggles are deeply connected to declining faith, particularly among young men.

Supporters of the legislation say publicly displaying the national motto is not only patriotic but also a reminder that faith has long played a central role in the nation’s identity and history.
