The most radical view will be that of mythology in the Bible. This is a difficult concept for most Christians to grasp, because most of us are taught that "myth" means a lie, that it's a dirty word, an insult, and that it is really debunking the Bible or rejecting it as God's word. The problem is in our understanding of myth. "Myth" does not mean lie; it does not mean something that is necessarily untrue. It is a literary genre—a way of telling a story. In Genesis, for example, the creation story and the story of the Garden are mythological. They are based on Babylonian and Sumerian myths that contain the same elements and follow the same outlines. But three things must be noted: 1) Myth is not a dirty word, not a lie. Myth is a very healthy thing. 2) The point of the myth is the point the story is making--not the literal historical events of the story. So the point of mythologizing creation is not to transmit historical events but to make a point. We will look more closely at these two points. 3) I don't assume mythology in the Bible out of any tendency to doubt miracles or the supernatural, I believe in them. I base this purely on the way the text is written.
In Kerenyi's essays on a Science of Mythology we find the two figures of the maiden and the Krone. These are standard figures repeated throughout myths of every culture. They serve different functions, but are symbolic of the same woman at different times in her life. The Krone is the enlightener, the guide, the old wise woman who guides the younger into maidenhood. In Genesis we find something different. Here the Pagan myths follow the same outline and contain many of the same characters (Adam and Adapa—see, Cornfeld Archaeology of the Bible 1976).
But in Genesis we find something different. The chaotic creation story of Babylon is ordered and the source of creation is different. Rather than being emerging out of Tiamot (chaos) we find "in the beginning God created the heavens and the earth." Order is imposed. We have a logical and orderly progression (as opposed to the Pagan primordial chaos). The seven days of creation represent perfection and it is another aspect of order, seven periods, the seventh being rest. Moreover, the point of the story changes. In the Babylonian myth the primordial chaos is the ages of creation, and there is no moral overtone, the story revolves around other things. This is a common element in mythology, a world in which the myths happen, mythological time and place. All of these elements taken together are called Myths, and every mythos has a cosmogony, an explanation of creation and being (I didn't say there were no explanations in myth.). We find these elements in the Genesis story, Cosmogony included. But, the point of the story becomes moral: it becomes a story about man rebelling against God, the entrance of sin into the world. So the Genesis account is a literary rendering of pagan myth, but it stands that myth on its head. It is saying God is the true source of creation and the true point is that life is about knowing God.
The mythological elements are more common in the early books of the Bible. The material becomes more historical as we go along. How do we know? Because the mythical elements of the first account immediately drop away. Elements such as the talking serpent, the timeless time ("in the beginning"), the firmament and other aspects of the myth all drop away. The firmament was the ancient world's notion of the world itself. It was a flat earth set upon angular pillars, with a dome over it. On the inside of the dome stars were stuck on, and it contained doors in the dome through which snow and rain could be forced through by the gods (that's why Genesis says "he divided the waters above the firmament from the waters below”). We are clearly in a mythological world in Genesis. The Great flood is mythology as well, as all nations have their flood myths. But as we move through the Bible things become more historical.
The NT is not mythological at all. The Resurrection of Christ is an historical event and can be argued as such (see Resurrection page). Christ is a flesh and blood historical person who can be validated as having existed. The resurrection is set in an historical setting, names, dates, places are all historically verifiable and many have been validated. So the major point I'm making is that God uses myth to communicate to humanity. The mythical elements create the sort of psychological healing and force of literary strength and guidance that any mythos conjures up. God is novelist, he inspires myth. That is to say, the inner experience model led the redactors to remake ancient myth with a divine message. But the Bible is not all mythology; in fact most of it is an historical record and has been largely validated as such.
The upshot of all of this is that there is no need to argue evolution or the great flood. Evolution is just a scientific understanding of the development of life. It doesn't contradict the true account because we don't have a "true" scientific account. In Genesis, God was not trying to write a science text book. We are not told how life developed after creation. That is a point of concern for science not theology.
How do we know the Bible is the Word of God? Not because it contains big amazing miracle prophecy fulfillments, not because it reveals scientific information which no one could know at the time of writing, but for the simplest of reasons. Because it does what religious literature should do, it is transformative.
