Should I Read the Bible as Literature?
Absolutely! In fact, the Bible reader must be a reader of literature. Why? First of all, the Bible as an anthology of literature, tells the story of humankind; it is a story of tradition revealing the present. Genesis chronicles the beginning of humankind. From the beginning, humans are described as finite creatures who must learn their limitations yet yearn for release from them. Eve is mother of humankind; Adam is formed from the earth itself, although made in the image of God, having the divine inbreathed; he asks for and is given a clone of himself to discover, ironically, that human will seeks in its own choices to pronounce "good" solely of itself, to deny its own nakedness and ignorance, to usurp divine right to autonomy, and to enter into a conflict with God, nature, and humankind. Apart from arguments of the existence or inexistence of this God, our literary inheritance provides us with a rich repository of perspectives on this experienced conflict.
The issues of "literal" or "symbolic" create an unfortunate tension for many beginning readers of the Bible. To begin to read, though, is to be drawn immediately into the middle of symbolism: the alphabet itself is a symbol system; words themselves form from an active combining of symbols, both in the creation of text and in the reading and interpretation of text. Not to read symbolically is not to read at all. The Oxford Companion to the Bible rightly cautions the reader about any stance taken toward symbolism.....
Reading the Bible as literature, one recognizes several familiar themes repeated: one is the theme of creation/new beginnings. We see this in reiterative story chains: Moses leads people through the sea onto dry land to begin a new life (Ex. 14-15); Joshua crosses the Jordan River (3.7-17); Jacob crosses the Jabbok in Gen. 32.22. In this, one discovers a reiteration of the original division of waters at creation, separating chaos from new order.
Yet another familiar theme is God's war against the godless. Destruction stories abound: Babylon (Jeremiah 50-51), Samaria and Jerusalem (2 Kings 17 and 25); prophecies of destructions against God's enemies (Jeremiah 46-49); Great flood (Gen 6-9); Soddom and Gomorrah (Gen 19); Noah and Lot fill the role of surviving remnant. The metaphor of cosmic war is a much repeated motif; look at
Psalms 2, 8, 89, 110. This cosmic war is picked up in the New Testament in the book of Revelation. Moreover, the reiterations continue the theme that God will preserve His own chosen remnant, both the literal Jerusalem and the spiritual New Jerusalem. Consider Zechariah: : Behold, the day of the LORD cometh, and thy spoil shall be divided in the midst of thee.
2: For I will gather all nations against Jerusalem to battle; and the city shall be taken, and the houses rifled, and the women ravished; and half of the city shall go forth into captivity, and the residue of the people shall not be cut off from the city.
3: Then shall the LORD go forth, and fight against those nations, as when he fought in the day of battle.
4: And his feet shall stand in that day upon the mount of Olives, which is before Jerusalem on the east, and the mount of Olives shall cleave in the midst thereof toward the east and toward the west, and there shall be a very great valley; and half of the mountain shall remove toward the north, and half of it toward the south.
5: And ye shall flee to the valley of the mountains; for the valley of the mountains shall reach unto Azal: yea, ye shall flee, like as ye fled from before the earthquake in the days of Uzziah king of Judah: and the LORD my God shall come, and all the saints with thee.
6: And it shall come to pass in that day, that the light shall not be clear, nor dark:
7: But it shall be one day which shall be known to the LORD, not day, nor night: but it shall come to pass, that at evening time it shall be light.
8: And it shall be in that day, that living waters shall go out from Jerusalem; half of them toward the former sea, and half of them toward the hinder sea: in summer and in winter shall it be.
9: And the LORD shall be king over all the earth: in that day shall there be one LORD, and his name one.
