One way to decide what we believe about the Bible is not to begin with some doctrinal stance we have consciously or unconsciously absorbed from our church background, but rather to approach it as historians looking at ancient documents, and on that basis decide what we want to believe about it.
The story of Israel begins in ancient Mesopotamia, a twin river valley running from what is now Southeast Turkey down to the Persian Gulf. According to the Genesis account, Abraham set out from here, going first northwest from Ur to avoid the desert, and then down south along the east coast of the Mediterranean Sea to what is now the land of Israel.
After a sojourn in Egypt, the Israelites returned to what is now Israel. They eventually formed themselves into a monarchy, but after three kings, some of the tribes broke away from Israel to form the kingdom of Judah. Both kingdoms spent much of their time as vassal states of Mesopotamian Empires. In the 8th Century B.C., the kingdom of Israel rebelled against its Assyrian overlords, but was subdued by the Assyrians. Thousands of Israelites were taken away as slaves and the Assyrians imported some people from other parts of their empire to be a ruling elite who would subdue any further rebellion.
It was once thought that all the Israelites had been deported and that the imports practised a corrupt version of Israelite faith. However, over the past 2-3 decades there has been a major re-evaluation of this claim. Based on scripture, such as 1 and 2 Chronicles, archaeological evidence, and DNA samples, it appears that many Israelites avoided deportation by the Assyrians and continued to practice Israelite faith in a way that was no more corrupt than that of the kingdom of Judah.
In the 6th Century B.C., the kingdom of Judah rebelled against its Babylonian overlords. They were subdued and thousand were taken away as slaves to Babylon. After a few generations, the Persians overthrew the Babylonians and the Judahites were permitted to return to Judea. But then the Greeks conquered the Persians and subdued both the remnant of the northern kingdom of Israel and the returned exiles of the kingdom of Judah. Eventually the Greeks were overthrown, first by the Judahites but eventually by the Romans. However, while the Romans conquered the Greeks militarily, the Greeks conquered the Romans linguistically, and Greek became the common language of the Western Roman Empire.
Sorry for the whirlwind tour of history, but it has to do with the language of the Bible and formation of the Bible. Early on in the history of Mesopotamia, the Assyrians conquered the kingdom of Aram militarily. However, the Aramaeans conquered the Assyrians, Babylonians and Persians linguistically. Instead of the more than 600 pictographs of Cuneiform, the Aramaeans had an alphabetic script based on the sounds of the spoken language made up of just 22 letters. Aramaic became the common language of these Mesopotamian Empires. So, there were two common languages: Greek in the West and Aramaic in the East.
Hebrew was a Canaanite language, but when the Judahite exiles returned from Babylon, they came back speaking Aramaic as their everyday language. Hebrew became the language of the Temple and the synagogue, but most importantly, the returning exiles began to write Hebrew language with Aramaic letters. And they still do to this day. Evidence of Hebrew written in the original Hebrew script comes mainly from Samaritan contributions to the Bible. Scholars believe that the first language of Jesus in his community would have been Aramaic. The writing of Hebrew in Aramaic script dates it to the Persian/Greek/Hasmonean period.
The relevance of all this to the way we perceive the Bible is the understanding that the books of the Hebrew Bible reached their final editing in the Persian/Greek/Hasmonean period in the few centuries before Christ. We are not able to step backwards from that time to investigate what theology the books would have revealed in earlier editions. The way they were written and the theology they espoused, date from that time.
Let me draw an analogy. Some centuries back, some German migrants came to a community interstate to where I live. A German expat friend of mine travelled over to visit their community. He was fascinated to find that they spoke a version of the German language that was antiquated – frozen in time – from the era of their migration.
The theology of the Old Testament is like that. Frozen in the time of the Persian/Greek/Hasmonean period. In that, we can see the human influence on revelation.
