What is meant by a lodge being just, perfect and regular?

The formula describing a lodge as just, perfect, and regular is a long-standing phrase within Masonic ritual tradition and catechisms. Historical ritual catechisms record that a lodge of Freemasons is declared to be opened or situated in the body of the Lodge, just, perfect and regular, as noted by Ars Quatuor Coronatorum (via The Square Magazine). In traditional usage, hailing from such a body signifies hailing from a lodge that is just and legally constituted 1.

The historical development of this description was examined by T. O. Haunch in his paper titled "The Lodge, Just, Perfect and Regular," published in 1969 in Ars Quatuor Coronatorum, the transactions of Quatuor Coronati Lodge No. 2076.

While the individual terms have been interpreted in various ways throughout Masonic history, the triad broadly defines the legal standing and internal constitution of a lodge. In early eighteenth-century catechisms and official documents, invoking these qualities served to affirm that a lodge was operating under proper authority, possessed the necessary charter or warrant, and assembled the requisite officers and members to perform its work, distinguishing it from an irregular or unauthorized gathering 1.

Seven Master Masons are generally required to petition for the authority to form a regular lodge 21. While historical writers such as Dalcho maintained that as few as three Master Masons could sign a petition, this stands apart from general authority 2. A petition signed by fewer than seven would present an absurdity in practice, as seven Masons are necessary to form a quorum for opening and conducting business in an Entered Apprentice's lodge 21.

Regarding the quorum required to open and hold a lodge, the ritual sets the necessary number according to the degree in which the lodge is opened 1. Seven Masons constitute a quorum in an Entered Apprentice's lodge, five in a Fellow Craft's lodge, and three in a Master Mason's lodge 1. Without the requisite number present for the specific degree, a lodge cannot be legally opened nor proceed to work or business 1.

The requirement that seven Masons make a lodge perfect originates in eighteenth-century ritual instructions and the traditional history of the Craft 1. Albert C. Mackey notes that the earliest eighteenth-century instructions cited the Seven Liberal Arts and Sciences—Grammar, Rhetoric, Logic, Arithmetic, Geometry, Music, and Astronomy—as the foundation of Freemasonry and the primary reason for the sacredness of that number in the lodge 1. Early printed catechisms and exposures, including *Jachin and Boaz* and *Three Distinct Knocks*, similarly ground the requirement of seven in these Seven Liberal Sciences.

Historical manuscript records compiled by Lodge of Research No. 2429 show that early requirements for a "true and perfect lodge" varied in their details. Documents such as the *Coustos* manuscript and the *Chesswell MS* specified a total of seven Masons—such as seven Master Masons, or four Masters and three Entered Apprentices—to ensure valid and proper admissions to the lodge.

While modern ritualism transferred much of the explicit explanation of the number seven to the Second Degree in connection with the winding stairs, the number seven remains fundamental across the system 1. From a practical standpoint, seven Master Masons became established as the necessary quorum to hold an Entered Apprentice lodge and the standard minimum required to petition for authority to constitute a new lodge 2.
