"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]Satanic "pertaining to Satan" is first recorded 1667 (in "Paradise Lost"); meaning "diabolical" is from 1793. Satanism "worship of Satan" dates from 1896, with ref. to France, where it was said to be active at that time; Satanist is attested from 1559, applied by their enemies to Protestant sects.
