The Deeper Symbolism of Freemasonry from The Meaning of Masonry by Walter Leslie Wilmshurst.

“For the moment let me merely say that behind all the official religion systems of the world, and behind all the great moral movements and developments in the history of humanity, have stood what St. Paul called the keepers or ‘stewards of the Mysteries.'” [via]

Consider also:

  1. “These Mysteries were formerly taught, we are told, ‘on the highest hills and in the lowest valleys,’ which is merely a figure of speech for saying, first, that they have been taught in circumstances of the greatest seclusion and secrecy, and secondly, that they have been taught in both advanced and simple forms according to the understanding of their disciples.”
  2. “We are told seven or more years was the normal period, though less sufficed in worthy cases. The most severe tests of discipline, of purity, of self-balance were required before a neophyte was permitted to pass forward, and a reminiscence of these tests of fitness is preserved in our own working by the conducting of the candidate to the two wardens, and submitting him to a merely formal trial of efficiency.”
  3. “Surely, then, it behoves us to acquaint ourselves with what that larger end consists, to enquire why the fulfilment of that purpose is worthy to be called a science, and to ascertain what are those ‘mysteries’ to which our doctrine promises we may ultimately attain if we apply ourselves assiduously enough to understanding what Masonry is capable of teaching us.”
  4. “To trace the genesis of the movement, which came into activity some 250 years ago (our rituals and ceremonies having been compiled round about the year 1700), is beyond the purpose of my present remarks. It may merely be stated that the movement itself incorporated the slender ritual and the elementary symbolism that, for centuries previously had been employed in connection with the mediaeval Building Guilds, but it gave to them a far fuller meaning and a far wider scope.”
  5. “I cannot too strongly impress upon you, Brethren, the fact that, throughout our rituals and our lectures, the references made to the Lodge are not to the building in which we meet. That building itself is intended to be but a symbol, a veil of allegory concealing something else.”
