No. If you are an atheist, you do not have to swear on the Bible in court. Every United States court, federal and state, must let you make a secular affirmation instead, and that affirmation carries the exact same legal weight as a religious oath. You do not need to explain your beliefs, file anything in advance, or justify the choice.
What to Say When It’s Your Turn
The mechanics are simple, and court staff deal with this all the time. When the clerk or bailiff starts with “Do you solemnly swear…,” interrupt politely with “I’d like to affirm.” The clerk will switch to secular wording, usually something close to: “Do you solemnly affirm that the testimony you are about to give will be the truth, the whole truth, and nothing but the truth?” You answer “I do.” That’s it.
If you have a lawyer, tell them before the hearing so they can give the clerk a heads-up. If you’re appearing on your own, the request at the stand is enough. There is no form to fill out and no requirement that you say why.
Raising your right hand is tradition, not law. The legal substance lives in the words. If raising your hand also conflicts with your conscience, say so to the clerk. Federal Rule of Evidence 603 requires only that the procedure impress the duty of truthfulness on your conscience, with no fixed physical script.1Legal Information Institute (LII) / Cornell Law School.

Why the Law Backs You Up
Article VI of the Constitution treats oaths and affirmations as equivalents and bars any religious test for public trust.2Constitution Annotated. Article VI – Supreme Law – Clause 3 The Supreme Court held in Torcaso v. Watkins that “neither a State nor the Federal Government can constitutionally force a person to profess a belief or disbelief in any religion.”3Justia US Supreme Court. Torcaso v Watkins, 367 US 488 (1961)
Federal Rule of Evidence 603 requires “an oath or affirmation to testify truthfully,” and Federal Rule of Civil Procedure 43(b) adds that “when these rules require an oath, a solemn affirmation suffices.”4Legal Information Institute (LII) / Cornell Law School. Federal Rule of Civil Procedure 43 – Taking Testimony Every state has an equivalent provision. A judge who refused to let you affirm would be committing reversible error.
Affirming Outside the Courtroom
The right to affirm applies anywhere the legal system asks you to swear.
Depositions. The court reporter administers an oath or affirmation at the start, and you have the same option you would at trial.
Written declarations. For federal filings, 28 U.S.C. § 1746 lets you submit an unsworn declaration “under penalty of perjury” instead of a sworn affidavit. The closing language is: “I declare under penalty of perjury that the foregoing is true and correct. Executed on [date].”5Office of the Law Revision Counsel. 28 USC 1746 – Unsworn Declarations Under Penalty of Perjury No notary, no Bible, no oath. It’s useful to know even if you’re not an atheist, because it eliminates the need to find a notary for many federal filings.
Notarized documents. When a document does require a notary, every state allows the notary to administer an affirmation in place of an oath. Fees are set by state law and typically run between $2 and $25.
Does Affirming Hurt You Legally or With a Jury?
Legally, no. An affirmation is not “less binding” than an oath. Lying after either one is perjury, a federal felony punishable by up to five years in prison.6Office of the Law Revision Counsel. 18 USC 1621 – Perjury Generally The federal perjury statute also reaches written declarations submitted under § 1746. State perjury statutes apply equally to affirmed testimony.
With a jury, the law also protects you. Federal Rule of Evidence 610 states: “Evidence of a witness’s religious beliefs or opinions is not admissible to attack or support the witness’s credibility.”7Legal Information Institute (LII) / Cornell Law School. Federal Rule of Evidence 610 – Religious Beliefs or Opinions An opposing attorney cannot argue that your choice to affirm makes you less trustworthy. Federal pattern jury instructions also tell jurors to set aside bias based on religious beliefs when weighing testimony.8Ninth Circuit District and Bankruptcy Courts. 6.9 Credibility of Witnesses
Implicit bias is harder to legislate away. If you or your attorney are worried that jurors might read something into your choice, a motion in limine filed before trial can ask the judge to prohibit any reference to it. Courts routinely grant these motions where the evidence would be irrelevant and potentially prejudicial. In practice, the issue rarely surfaces. Jurors hear the affirmation, the trial moves on, and the wording is forgotten.
