Which president didn't get sworn in with a Bible

So you're wondering which president skipped the Bible at their swearing-in? That'd be John Quincy Adams. Back on March 4, 1825, he put his hand on a law book instead—specifically a copy of the U.S. Constitution. It's still the only time that's happened in American history. Most presidents grab a family Bible or some historic one, but Adams? He made a deliberate choice. A symbolic one. He wanted to show his commitment to the rule of law, plain and simple.

Why did John Quincy Adams choose a law book instead of a Bible?

John Quincy Adams was stubborn about his principles. A real stickler for separating church and state. His decision to swear in on a law book instead of a religious text? That was him making a point. He saw the presidential oath as a legal promise to the American people and the Constitution—not a religious one. The Constitution was the highest law in his eyes, and placing his hand on it meant he was loyal to that document above everything else. It fit perfectly with his whole deal about reason, law, and keeping the republic secular.

Were there any other presidents who did not use a Bible at their inauguration?

Yeah, there's a few exceptions, though Adams is the only one who deliberately used a law book. The big one is Theodore Roosevelt. After McKinley got assassinated in 1901, they rushed him into office at some guy's house in Buffalo, New York. No Bible around in the chaos. So he just raised his hand—or shook someone's hand, depending on who you ask—and took the oath without any book. Later he did the whole thing again with a Bible in a more formal setting. And some early presidents like Thomas Jefferson used a Bible but never kissed it, which later became a thing. The Bible tradition is strong, sure, but legally? Not required at all.

What is the exact wording of the presidential oath?

The oath comes straight from Article II, Section 1, Clause 8 of the Constitution. Here's exactly what they say: "I do solemnly swear (or affirm) that I will faithfully execute the Office of President of the United States, and will to the best of my Ability, preserve, protect and defend the Constitution of the United States." Notice how the Constitution doesn't mention a Bible or any religious object? Yeah, that's intentional. The Bible thing is just tradition. The law only demands they say those words. And the "or affirm" part? That gives presidents a secular out if they want one.

Is it a legal requirement for a president to use a Bible?

Nope, not at all. The Constitution says nothing about a Bible or any religious text for the inauguration. All they gotta do is take the oath. The tradition started with George Washington using a Masonic Bible, and pretty much every president since has followed along. But what you put your hand on—if anything—is totally up to the president-elect. The law doesn't care. So John Quincy Adams choosing a law book was perfectly legal. It actually highlights the separation of church and state, since the oath is a civil thing, not religious.

What are the most common traditions associated with the presidential inauguration Bible?

Even though it's not required, some traditions have stuck. Most presidents pick a family Bible—often one with some history behind it. They'll open it to a verse that means something to them personally. Take George W. Bush—he used the same Bible his dad used, opened to a verse about faith. The Chief Justice of the Supreme Court usually holds the Bible while administering the oath. Some presidents, like Lincoln, borrowed a Bible from the Supreme Court itself. The choice is usually personal, symbolic, reflecting their faith and background. But again, no legal weight behind it.

Did any president use a book other than a Bible or law book?

Not really. The only documented cases of presidents skipping the Bible are John Quincy Adams (law book) and Theodore Roosevelt (no book at all). No one's used the Quran or the Torah or some random novel. The tradition is overwhelmingly Bible-focused. But legally, there's nothing stopping a future president from picking whatever book they want. Adams's law book choice is still the most famous break from the norm—and it was totally deliberate.
