Freemasonry is a philosophy and practice of morality and ethics imparted to its members through the symbolic use of the tools of ancient stonemasons and by initiation ceremonies based upon rituals that are centuries old. Freemasons uniquely use 18th century language and rituals to teach 21st century values.
The heritage of modern Freemasonry is derived from the organized guilds or unions of stonemasons who constructed the beautiful cathedrals and other stately structures throughout Europe during the middle ages. Over time, the demand for operative stonemasons declined until they were eventually replaced with members who emphasized the teaching of moral philosophy rather than the technical and working skills of earlier centuries.
Tools of the stonemasons are still used in Freemasonry today but only to symbolize moral virtue, not to build cathedrals.
