LOST WORD
According to Masonic legend, the true password of a Master Mason was lost when Hiram Abiff, the master architect of King Solomon’s Temple, was murdered by three craftsmen. Since the true word was lost, King Solomon is said to have established a replacement for it, the word now used in Masonic practice as the Master’s Word. See Freemasonry; Hiram Abiff.
This legend offered an obvious opportunity to the creators of higher degrees. Starting in the middle of the eighteenth century degrees were in circulation purporting to reveal the true Lost Word, and most systems of high degrees introduce at least one such word to candidates; the Scottish Rite, the most popular system of higher degrees in Masonry, presents three such words to its initiates at different points along its sequence of degrees. Many Masonic writers, however, argue that the true Lost Word is a symbol of divine truth, which can only be discovered within the self through prayer, meditation, and moral effort. See Ancient and Accepted Scottish Rite (AASR); high degrees.
