In biblical sources the Hebrew term the satan describes an adversarial role. It is not the name of a particular character. Although Hebrew storytellers as early as the sixth century B.C.E. occasionally introduced a supernatural character whom they called the satan, what they meant was any one of the angels sent by God for the specific purpose of blocking or obstructing human activity. [Elaine Pagels, "The Origin of Satan," 1995]Satanist is attested from 1550s, applied by their enemies to Protestant sects.
Satire, n. An obsolete kind of literary composition in which the vices and follies of the author's enemies were expounded with imperfect tenderness. In this country satire never had more than a sickly and uncertain existence, for the soul of it is wit, wherein we are dolefully deficient, the humor that we mistake for it, like all humor, being tolerant and sympathetic. Moreover, although Americans are 'endowed by their Creator' with abundant vice and folly, it is not generally known that these are reprehensible qualities, wherefore the satirist is popularly regarded as a sour-spirited knave, and his every victim's outcry for codefendants evokes a national assent. [Ambrose Bierce, "Devil's Dictionary," 1911]
Proper satire is distinguished, by the generality of the reflections, from a lampoon which is aimed against a particular person, but they are too frequently confounded. [Johnson]
[I]n whatever department of human expression, wherever there is objective truth there is satire [Wyndham Lewis, "Rude Assignment," 1950]
