In a godly, devout, or pious manner; with reverence, virtue, and moral righteousness.
From 'godly' + '-ly' adverbial suffix (Old English origin). A double suffix construction (-ly on an adjective already derived from 'god') creating an adverb of manner.
This word is vanishingly rare in modern English because religious behavior is no longer typically described this way—its rarity traces changing attitudes about how we publicly discuss piety and devotion.
