""Freemasonry is a fraternal organization, existing in various forms worldwide, whose membership has shared moral and metaphysical ideals and in most of its branches requires a constitutional declaration of belief in a Supreme Being.[1]
The fraternity uses the metaphor of operative stonemasons' tools and implements, against the allegorical backdrop of the building of King Solomon's Temple, to convey what is most generally defined as "a system of morality veiled in allegory and illustrated by symbols."[2]""
