Those who talk of reading the Bible "as literature" sometimes mean, I think, reading it without attending to the main thing it is about; like reading Burke with no interest in politics, or reading the Aeneid with no interest in Rome. That seems to me to be nonsense. But there is a saner sense in which the Bible, since it is after all literature, cannot properly be read except as literature; and the different parts of it as the different sorts of literature they are. Most emphatically, the Psalms must be read as poems; as lyrics, with all the licenses and all the formalities, the hyperboles, the emotional rather than logical connections, which are proper to lyric poetry.
C.S. Lewis, Reflection on the Psalms, p. 3.
