What does the phrase "to be one, ask one" signify?

The phrase "to be one, ask one" signifies the understanding that only a Mason can initiate someone into the fraternity of Freemasonry. It underscores the importance of personal connection and endorsement within the Masonic community. This phrase suggests that an individual who wishes to join the ranks of Freemasons should seek out a current member, who will not only act as a guide but also vouch for the individual's character and intent to join the lodge. Therefore, initiation into Freemasonry is not a simple application process; rather, it relies on the existing brotherhood to ensure that candidates are suitable and fit for membership. This principle emphasizes the value placed on personal relationships and the integrity of the decision-making process surrounding initiation.

The other options do not reflect the core message of the phrase. For example, while some lodges may initiate members in groups, this is not a universal requirement. Public invitations to initiation ceremonies are not typically in line with Masonic traditions, which value discretion and privacy. Similarly, while secrecy is indeed an important aspect of Masonic practices, the phrase itself specifically highlights the role and responsibility of Masons in bringing new members into the fold.
