A more thorough explanation:

Definition: Corporale sacramentum is a type of oath that is made solemn by touching a sacred object, such as the Bible. It is also known as a corporal oath or solemn oath. The person taking the oath is making a solemn declaration, accompanied by a swearing to God or a revered person or thing, that their statement is true or that they will be bound to a promise. The legal effect of an oath is to subject the person to penalties for perjury if the testimony is false.

Example: In a courtroom, a witness takes a corporal oath by placing their hand on the Bible and swearing to tell the truth, the whole truth, and nothing but the truth. This is a solemn declaration that their testimony is true and they will be punished if they lie under oath.

Explanation: The example illustrates how a corporal oath is used in a legal setting to ensure that witnesses tell the truth. By touching a sacred object, the witness is making a solemn declaration that they will be bound to the truth and will face punishment if they lie. This type of oath is taken very seriously and is an important part of the legal system.
