The concept of "regularity" is associated
with the ideas of the oldest Masonic Grand Lodges about the correctness of the Masonic practice and the conformity of this practice to the basic Masonic standards. The meaning of this word and this concept for Freemasonry should be sought, first of all, in its literal sense. Regularity – means "correctness", "ordinariness". The vast majority of the Grand Lodges of the world united themselves into a single chain, consolidated around simple principles, which are called the principles of regularity.
The regularity of the Grand Lodge is the basis for its recognition by other Grand Lodges, the basis for its involvement in the fraternal chain.
As noted at the conference of the Grand Masters of the world in 2002 , the Executive Secretary of the conference, Thomas W.Jackson: "Today we confirm that the regularity of the Grand Lodge can only be if it is established by another regular Grand Lodge or by three or more regular lodges under the jurisdiction of the regular Grand Lodges. Regularity also depends on the Grand Lodge maintaining standards of regularity in its practical work. These include belief in a Supreme Being, the presence of the Book of the Sacred Law on the altar, access to membership only for men, exclusion of political and religious discussions in the Lodge, restrictions due to the impossibility of fraternal relations with irregular Freemasonry, and respect for the territorial sovereignty of other Grand Lodges. The latter requirement was recently changed due to the possibility of recognizing more than one Grand Lodge in the same territory if these Grand Lodges recognize each other."
The most important document for defining the principles of regularity is the Basic Principles of Recognition of the United Grand Lodge of England (Basic Principles for recognition), adopted by the UGLE on
July 4, 1929 and the Twelve Points of Regularity adopted by the Grand National Lodge of France.
