In chapter 4 of Jesus Christ and Mythology (New York: Charles Scribner's Sons: 1958), titled "Modern Biblical Interpretation and Existentialist Philosophy", Rudolf Bultmann made several observations that I found worth sharing (or, at least typing out as a means of remembrance):
(1) Bultmann clarifies, "...that demythologizing is a hermeneutic method, that is, a method of interpretation, of exegesis." (p. 45) He emphasizes a handful of times that de-mythologization is a method, admitting that it is based in his own philosophical presuppositions about the world. He says more on this.
(2) He writes, "interpretation, that is, exegesis, is always based on principles and conceptions which guide exegesis as presuppositions, although interpreters are often not aware of this fact." (p. 46)
(3) "...every interpreter brings with him certain conceptions, perhaps idealistic or psychological, as presuppositions of his exegesis, in most cases unconsciously. But then the question arises, which conceptions are right and adequate? Which presuppositions are right and adequate? Or is it perhaps impossible to give an answer to these questions? (p. 48)
(4) "It could be said that method is nothing other than a kind of questioning, a way of putting questions. This means that I cannot understand a given text without asking certain questions of it." (pp. 49-50)
(5) "This is, then, the basic presupposition for every form of exegesis: that your own relation to the subject-matter prompts the question you bring to the text and elicits the answers you obtain from the text." (p. 51)
(6) "Now, when we interpret the Bible, what is our interest? Certainly the Bible is an (sic) historical document and we must interpret the Bible by the methods of historical research." (pp. 51-52)
(7) "It is beyond the competence of critical study that I should hear the word of the Bile as a word addressed personally to me and that I should believe in it. This personal understanding, in traditional terminology, is imparted by the Holy Spirit, who is not at my disposal." (p. 54)
