Rudolf Karl Bultmann
Rudolf Karl Bultmann (August 20, 1884, Wiefelstede – July 30, 1976, Marburg) was a German Lutheran theologian and professor of New Testament at the University of Marburg. He was one of the major figures of early 20th century biblical studies and a prominent voice in liberal Christianity.
Bultmann is known for his belief that the historical analysis of the New Testament is both futile and unnecessary, given that the earliest Christian literature showed little interest in specific locations.] Bultmann argued that all that matters is the "thatness", not the "whatness" of Jesus, i.e. only that Jesus existed, preached and died by crucifixion matters, not what happened throughout his life.
Bultmann relied on demythologization, an approach interpreting the mythological elements in the New Testament existentially. Bultmann contended that only faith in the kerygma, or proclamation, of the New Testament was necessary for Christian faith, not any particular facts regarding the historical Jesus.
“When reason has followed its road to the end, the point of crisis is reached and man is brought to the great question mark over his own existence.”
“The historical method includes the presupposition that history is a unity in the sense of a closed continuum of effects in which individual events are connected by the succession of cause and effect....This closedness means that the continuum of historical happenings cannot be rent by the interference of supernatural transcendent powers and that therefore there is no "miracle" in this sense of the word.”
“Can Christian preaching expect modern man to accept the mythical view of the world as true? To do so would be both senseless and impossible. It would be senseless, because there is nothing specifically Christian in the mythical view of the world as such. It is simply the cosmology of a pre-scientific age.”
