For believers, certain divine mysteries lie beyond the reach of pure logic.
Note
Here the thing is unknown by nature, not for lack of evidence. A puzzle in the everyday sense may yet be solved, but a mystery of faith cannot be reasoned out. Jonathan Swift's A Sermon on the Trinity (first printed 1744) shows the usual construction, "this great mystery of the Trinity." Swift adds that even revealed mysteries would stay beyond understanding without further divine help.

Less common meanings
- 4A medieval religious drama enacting biblical stories, also called a mystery play.
Medieval guilds competed to produce the most elaborate mystery.
The cycle of mysteries told the whole biblical story from creation to judgment.
Note
Medieval stage history sets this word beside its neighbor. George Borrow, in Wild Wales (1862), compares the Mysteries with the Moralities and finds the Moralities more inventive, because they personified virtues, vices and qualities and often had something like a plot. That contrast is the useful one to keep in mind. In this sense the word often appears capitalized and plural, naming the genre as a whole.

Similarrite
Note
Here the word stands closest to its Greek root, where the initiated one is meant literally. It is chiefly plural and usually named for a place or god: the Eleusinian mysteries, the Mysteries of Mithras, the Orphean mysteries. Lewis Spence's Mysteries of Britain (1928) extends it to a British tradition. Joseph Conrad's Heart of Darkness (1899) keeps the tie to initiation, speaking of "no initiation either into such mysteries."

- 8A secret or mystical meaning concealed beneath the surface of a text or sign.
Note
The interpreter's sense, now gone from the language: what lay inside a plan or a sign for those who could read it. Geffraie Fenton's 1567 translation of Bandello sets it beside the plain word, in 'the meaning or misterie of her pollicie.' Today say hidden meaning or significance instead. The sense stays close to the Greek root, mústēs 'initiated one', from a verb meaning 'I shut': knowledge closed to outsiders.

1776, Adam Smith, An Inquiry into the Nature and Causes of the Wealth of NationsNote
Adam Smith still uses it in 1776, in An Inquiry into the Nature and Causes of the Wealth of Nations, as the third of a set: "The trades, the crafts, the mysteries." That company is the best guide to the archaic sense, which means a skilled occupation and, by extension, the body of craftsmen who practice it. Today it belongs to historical writing, and elsewhere most readers will hear "secret" before "trade."

Origin
Ancient Greek múō ("I shut") lies at the root of mústēs ("initiated one"), which gave mustḗrion, meaning "a mystery, a secret, a secret rite." Latin borrowed this as mysterium, and it reached English through Anglo-Norman misterie and Middle English. The word replaced the native Old English ġerȳne.
