Not all of Christendom believes all of the Bible literally. The Roman Catholic and Eastern Orthodox, and probably Anglican Churches view it as largely metaphorical and allegorical. Even when I was Christian I did not take it literally. My priest in the Eastern Orthodox Church used to say "what does it matter if Adam and Eve actually existed? The important thing is that we do exist to give glory to God". Yet there are large numbers in various Christian denominations that take the Bible literally. Why? Does taking it as largely allegorical somehow diminish any truths or lessons it holds? Does that make it false?
Using my own Hinduism for example, it's safe to say the overwhelming number of Hindus do not take most of our scriptures or stories literally, specifically the puranas. The Vedas are the exception in that they're generally accepted lock, stock and barrel because they are apauruṣeya (lit. means "not of man", i.e. divinely inspired). But they are not the equivalent of the Bible. The Vedas are hymns, poems, prayers, musings and treatises on theology, ontology and epistemology, and the world, etc. In the Nasadiya Sukta the Rig Veda even questions how creation came about. That said, that we don't take most of our texts literally doesn't diminish their value as being divinely inspired and holding truths.
So why is it so important that the Bible be interpreted literally?
Jainarayan,
There are two ways to consider literal. The Bible is literal as to the message written from our Creator!!!
The words were written in several different languages, and, especially in Hebrew and Aramaic, you cannot take literally, in many cases. The reason for this is because Hebrew, just like English, was living language, and was changing lol the time.
If a Bible translator tried to write the Bible using literal words of today, we would not be able to tell what it was saying, we would never get a correct message. The Bible must be translated in the exact meaning that the words had at the time of writing. This is very difficult today, and takes much, much study. This is one, very correctly called a Bible Scholar. Today, we do not need to understand the old Hebrew, we have many scholars who have proven to be trustworthy. Each different translation should be compared with other translations, if you want the truth.
The Almighty God Jehovah has even promised to make sure that the Bible will be accurate throughout all generations, Psalms 12:6,7, Isaiah 40:8, 1Peter 1:25. There are mistakes in all Bibles, but they can easily be found by comparing different translations.
Agape!!!
