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?.................................
So why is it so important that the Bible be interpreted literally?
Of course, Jesus' parables or illustrative stories are Not literal happenings but lessons to remember and learn.
However, I do wonder why the E.O. church would think or doubt about a literal Adam and Eve.
If Adam and Eve were Not real, then how could Jesus be related to them as per Luke 3:38 _________
Plus, the Jewish ancestral record list starting at 1 Chronicles 1:1 lists Adam as a real live person.
Ezra considered what Moses wrote, as Moses being a man of God - Ezra 3:2 B.
Moses considered the first man as a real man as per Deuteronomy 4:32 besides what he wrote in Genesis.
