- Freemasonry
- A worldwide fraternal order of men who profess belief in a Supreme Being. The Fraternity describes itself, in its own published lectures, as a peculiar system of morality, veiled in allegory and illustrated by symbols.
- Speculative Masonry
- The moral and symbolic Masonry of today, descended from but distinct from the medieval operative craft of building in stone.
- Operative Masonry
- The actual trade of building in stone, practiced by the medieval guilds from which speculative Masonry inherited its tools, terms, and ceremonial framework.
- Brotherly Love
- The first of the three Great Tenets. By the exercise of Brotherly Love, Masons are taught to regard the whole human species as one family.
- Relief
- The second of the three Great Tenets. To soothe the unhappy, to sympathize with their misfortunes, to compassionate their miseries, and to restore peace to their troubled minds.
- Truth
- The third of the three Great Tenets. To be good and true is the first lesson taught in Masonry. Sincerity and plain dealing distinguish a Mason.
- Cardinal Virtues
- The four classical virtues which Masonry expressly inculcates: Temperance, Fortitude, Prudence, and Justice.
- Society with secrets
- How Masonry describes itself when distinguishing its character: it is not a secret society, but a society which preserves certain modes of recognition. Its purposes, its existence, its members' identities, and its published teachings are all public.
- Supreme Being
- A belief in a Supreme Being is a published requirement of the Fraternity. Masonry does not define which faith, denomination, or theology, only that the candidate professes such belief sincerely.
- Tenet
- A principle or teaching held to be true by the Fraternity. The three Great Tenets are Brotherly Love, Relief, and Truth.
