A pious fiction is a narrative that is presented as true by the author, but is considered by others to be fictional albeit produced with an altruistic motivation. The term is sometimes used pejoratively to suggest that the author of the narrative was deliberately misleading readers for selfish or deceitful reasons. The term is often used in religious contexts, sometimes referring to passages in religious texts.
An early use of the phrase was in 1862 in the British newspaper The Examiner.
The pious fiction of the dream of the herdsman Caedmon, and the direct interposition from heaven that gave to the noble paraphrase of Scripture stories into English verse made for the religious bouse of Whitby, stronger hold on the surrounding peasantry, for whose instruction it was made, was a fraud honestly meant, and may escape blame if interpreted by the imperfect ethics of that day, which now disgrace only as an anachronism some orders in the Roman Church.
