The number one is not listed among the primary symbolic or sacred numbers of Freemasonry, which are traditionally odd numbers such as three, five, seven, nine, twenty-seven, and eighty-one 2.

Where the concept of unity or oneness is represented geometrically, Carl H. Claudy notes that early man depicted the existence of a single universal Deity by drawing a point, using it to express the unity of God 1. Aside from this geometrical representation of divine unity through the point, the sources do not assign a standalone degree symbol or ritual lesson to the number one itself.

In the numerical symbolism adapted from the Pythagorean tetractys into the English lectures, a single point or monad represents unity and answers geometrically to a point 2. It serves as the primary principle through whose multiplication all subsequent combinations of form and number are generated 2. Within this symbolic arrangement, the single point acts specifically as an emblem of the Active Principle or Creator 2.

Beyond geometric structure, the concept of oneness expresses the foundational philosophical ties of the fraternity. The belief in the Fatherhood of God and the Brotherhood of Man serves as a basic founding principle, highlighting that true unity among people relies upon a shared sense of brotherhood, as an article on the Grand Lodge of India's website notes.

Numbers in Masonic symbolism serve purely as emblems of specific ideas rather than possessing occult virtues, with the primary symbolic numbers traditionally being odd figures beginning with three 2. The number one does not feature as a standalone sacred number in the ritual, but its symbolic significance is expressed through the concept of unity and the monad 2.

Geometrically, the concept of a single universal Deity was first depicted as a simple point to represent divine unity 1. In the English lectures revised by Samuel Hemming following the Union of 1813, the first point of the Pythagorean tetractys represents unity and is termed a monad 2. Geometrically answering to a point, this monad acts as the primary principle from whose multiplication all subsequent combinations of form and number are generated 2. Within this arrangement, the single point serves specifically as an emblem of the Active Principle or Creator 2.
