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

“We meet in our Lodges regularly we perform our ceremonial work and repeat catechetical instruction-lectures night after night with a less or greater degree of intelligence and verbal perfection, and there our work ends, though the ability to perform this work creditably were the be-all and the end-all of Masonic work: Seldom or never do we employ our Lodge meeting for that purpose for which, quite as much as for ceremonial purposes, they were intended, for ‘expatiating on the mysteries of the Craft,’ and perhaps our neglect to do so is because we have ourselves imperfectly realized what those mysteries are into which our Order was primarily formed to introduce us.” [via]
