Although it is correct to say that The Bible is considered to be mythology, it is important to define the term as it is used by scholars of literary criticism. A "myth" is a story that provides meaning beyond the literal details contained in the narrative. Myths speak to specific cultures or communities, providing common history, identity and spiritual purpose. To say that a story is "myth" says nothing about the story's historical or factual truth.
