WASHINGTON (TNND) — During his inauguration, a photo captured President Donald Trump not putting his hand on the Bible as he took an oath of office, and social media was quick to react.

According to Article VI, Clause 3, of the U.S. Constitution, it is not legally required and there are no specifics for how it must be done.

“The Senators and Representatives before mentioned, and the Members of the several State Legislatures, and all executive and judicial Officers, both of the United States and of the several States, shall be bound by Oath or Affirmation, to support this Constitution; but no religious Test shall ever be required as a Qualification to any Office or public Trust under the United States,” the clause states.

Supreme Court Chief Justice John Roberts issued the oath of office as Trump’s wife, Melania, held a family Bible reportedly given to him by his mother and the Lincoln Bible, the first used to swear in the 16th president in 1861.

“I swear 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, so help me God,” Trump repeated after the chief justice.

Vice President JD Vance took the oath of office before Trump and placed his right hand on the Bible with his wife and three children by his side.

During his inauguration speech, Trump credited God for protecting his life when he was shot in the ear by an assassination attempt in July during a campaign rally in Butler, Pennsylvania.

“Just a few months ago, in that beautiful Pennsylvania field, an assassin’s bullet ripped through my ear,” Trump told the crowd. “But I felt then, and believe even more so now, that my life was saved for a reason. I was saved by God to make America great again.”
