oath. 1. A solemn declaration, accompanied by a swearing to God or a revered person or thing, that one’s statement is true or that one will be bound to a promise. • The person making the oath implicitly invites punishment if the statement is untrue or the promise is broken. The legal effect of an oath is to subject the person to penalties for perjury if the testimony is false. [Cases: Oath 1; Witnesses 227. C.J.S. Oaths and Affirmations §§ 1–2, 8–11; Witnesses§ 394.] 2. A statement or promise made by such a declaration. 3. A form of words used for such a declaration. 4. A formal declaration made solemn without a swearing to God or a revered person or thing; AFFIRMATION.

“The word ‘oath’ (apart from its use to indicate a profane expression) has two very different meanings: (1) a solemn appeal to God in attestation of the truth of a statement or the binding character of such a promise; (2) a statement or promise made under the sanction of such an appeal.” Rollin M. Perkins & Ronald N. Boyce, Criminal Law 515 (3d ed. 1982).

corporal oath (kor-p<<schwa>>r-<<schwa>>l). An oath made solemn by touching a sacred

“Oath (Juramentum) Is a calling Almighty God to witness that the Testimony is true; therefore it is aptly termed Sacramentum, a Holy Band, a Sacred Tye, or Godly Vow. And it is called a Corporal Oath, because the party when he swears, toucheth with his right hand the Holy

Evangelists or Book of the New Testament.” Thomas Blount, Nomo-Lexicon: A Law-Dictionary (1670).
