What term is used to refer to the pass?

The term "Shibboleth" is commonly used in Masonic contexts to refer to a specific pass or word that identifies members of a particular group. In the context of Freemasonry, a Shibboleth serves as a means of recognition and a test of one's membership. It originates from a biblical story where the pronunciation of the word distinguished those who were part of a group from outsiders. Thus, in Masonic practice, a Shibboleth reinforces the bonds of brotherhood and ensures that members can recognize each other based on shared knowledge and experience.

The other options refer to different symbols or concepts within Freemasonry. A signet is typically a seal used to authenticate documents, a key symbolizes access or knowledge but does not specifically denote a pass like the Shibboleth. An emblem is a symbol that represents broader concepts or teachings in Freemasonry, but it does not have the specific function of a pass. Therefore, "Shibboleth" is the most accurate term to describe the concept of a pass within this context.
