Why was the pass instituted in the ritual?

The correct answer highlights the significance of the pass as a response to historical events or conflicts that may have arisen within the traditions of Freemasonry. The institution of the pass is often associated with a need for clarity and delineation within the Masonic ceremonies, created in the wake of misunderstandings and disputes that warranted a structured method of recognition among members. This system carries deep roots in Masonic history, where rituals often serve both to educate and preserve the integrity of the brotherhood.

While the other reasons might seem plausible within the context of the organization's values—such as honoring ancient traditions, promoting unity among members, or marking a completion of a stage—these aspects do not address the specific circumstances that led to the establishment of the pass. The focus on disagreement emphasizes the need for clarity and mutual recognition that was a decisive factor in shaping Masonic rituals, ensuring that brethren could identify one another reliably and maintain the integrity of their fraternal bond.
