Demythologization

Demythologization as a hermeneutic approach to religious texts seeks to separate cosmological and historic claims from philosophical, ethical and theological teachings. Rudolf Bultmann (1884–1976) introduced the term "demythologization" (in German: "Entmythologisierung") in this context,
but the concept has earlier precedents.
Spinoza's hermeneutic approach to Scripture.
In his 1677 "Theologico-Political Treatise", Spinoza argues that any event in Scripture which is inconsistent with natural laws must be interpreted either as unreliable testimony or as a metaphorical or allegorical representation of a moral teaching. Because the masses are "wholly ignorant of the workings of nature", they are prone to interpret any natural event they can not explain as a miracle, and this "ridiculous way of expressing ignorance" often finds its way into Scripture. Scripture aims not at narrating things in terms of their natural causes, but rather at exciting the "popular imagination" in order to "impress the minds of the masses with devotion."Therefore it speaks inaccurately of God and of events, seeing that its object is not to convince the reason, but to attract and lay hold of the imagination. If the Bible were to describe the destruction of an empire in the style of political historians, the masses would remain unstirred.In order to correctly interpret scripture we must understand the opinions and judgments of the ancients and learn common "Jewish phrases and metaphors." Otherwise we will be prone to "confound actual events with symbolical and imaginary ones."Many things are narrated in Scripture as real, and were believed to be real, which were in fact only symbolical and imaginary.
Kant's "Religion Within the Limits of Reason Alone".
Immanuel Kant's 1793 "Religion Within the Limits of Reason Alone" argues that the New Testament teaches a hermeneutic strategy in which "not scriptural scholarship but the pure religion of reason must be the law's interpreter."[Jesus] claims that not the observance of outer civil or statutory churchly duties but the pure moral disposition of the heart alone can make man well-pleasing to God (Mt 5:20–48); … that injury done one’s neighbor can be repaired only through satisfaction rendered to the neighbor himself, not through acts of divine worship (Mt 5:24). Thus, he says, does he intend to do full justice to the Jewish law (Mt 5:17); whence it is obvious that not scriptural scholarship but the pure religion of reason must be the law’s interpreter, for taken according to the letter, it allowed the very opposite of all this.Kant understood the Pharisees to have interpreted the Old Testament as a statutory religion, and he claims that the New Testament intends to replace statutory religion with a "moral religion," which combines all duties into a single universal rule, "Love thy neighbor as thyself."Whatever, over and above good life-conduct, man fancies that he can do to become well-pleasing to God is mere religious delusion.Such delusions, Kant argues, must be abandoned to fulfill the New Testament's demand for a rational religion.
Bultmann's "New Testament and Mythology".
The German theologian Rudolf Bultmann argues in his 1941 "New Testament and Mythology" that it is no longer plausible to demand that Christians accept the "mythical world picture" of the New Testament.We cannot use electric lights and radios and, in the event of illness, avail ourselves of modern medical and clinical means and at the same time believe in the spirit and wonder world of the New Testament.To interpret New Testament mythology in cosmological terms, as a description of the universe, is not plausible. This interpretation must be superseded by an anthropological interpretation that "discloses the truth of the kerygma as kerygma for those who do not think mythologically."Can the Christian proclamation today expect men and women to acknowledge the mythical world picture as true? To do so would be both pointless and impossible. It would be pointless because there is nothing specifically Christian about the mythical world picture, which is simply the world picture of a time now past which was not yet formed by scientific thinking. It would be impossible because no one can appropriate a world picture by sheer resolve, since it is already given with one’s historical situation.
