Why this word is great
ENCYCLICAL — [Adjective, Noun] A papal letter for general circulation among bishops and the faithful; as an adjective, intended for wide dissemination. From the Late Latin encyclicus, from the Ancient Greek ἐγκύκλιος (enkúklios, "circular, general"), from ἐν- (en-, "in") + κύκλος (kúklos, "circle"). Unlike a papal "bull" — a weighty, sealed instrument for specific decree — or a bishop's "pastoral letter" — a locally bounded directive — an encyclical is the Pope's own teaching voice cast in a wide, deliberate orbit. It is the rustle of vellum copies dispatched from Rome, the sonorous Latin cadences echoing in a thousand stone naves, and the faint tremor sent through the secular world's foundations — a word made not for the vault but for the current, carrying doctrine on the common air to draw a disparate world into a single, contemplating circle.
