The chief architect of Solomon’s Temple was and is often referred to as “The Builder”. The term is also applied generally to the Craft, for every speculative Mason is as much a builder as was his operative predecessor. Masons are also known as moral builders. As the operative Mason spreads the cement to bind the stone, speculative Masons spread Brotherly love, relief, and truth to bind men morally and spiritually. The operative builder builds for a century and the speculative builds for eternity. In this sense, “The Builder” is the most noble title that can be bestowed upon a Mason.
