What is referred to as the sacred geometry

Geometry itself is given a sacred and divine character within the Craft, rather than being treated merely as an arithmetical or physical study 23. In the Old Constitutions and medieval manuscripts, such as the Regius and Harleian manuscripts, the science of geometry is used synonymously with Masonry itself, described as the foundational science upon which the entire superstructure rests 1.

William Preston notes that geometry, as presented in the Fellow Craft degree, is of a divine and moral nature, serving to prove the properties of nature while demonstrating moral truths 3. Carl Claudy similarly emphasizes that geometry functions in the second degree as a symbol of order, law, and universality 2. Through its unchanging principles—observable throughout creation in planetary orbits, snowflakes, and organic forms—geometry acts as a symbol by which man recognizes the order of Deity, referred to symbolically as the Great Geometer 2.
