The study of Scripture I find to be quite like mastering an instrument. No one is so good that they cannot get any better; no one knows so much that they can know no more. A professional can spot an amateur or a lack of practice or experience a mile away. His technicality, his spiritual ear is razor-sharp. He is familiar with the common mistakes, the counter-arguments; and insofar as this, he can clearly distinguish the difference between honest critics of the Faith and mere fools who criticize that which they know nothing.
It will not, however, affect one tiny bit the question of whether the text has a literal meaning because—mark this—every biblical text has a literal meaning. Many people are stunned to hear this. That is because many people think a "literal meaning" can only be conveyed by literal language. They make the mistake of assuming that an author who uses metaphor, fiction, hyperbole, or various other figures of speech does not have a literal meaning. Thus, for instance, if I say "my heart is broken", some people mistakenly imagine that I "meant nothing literally." But, of course, I do. I literally mean I am deeply grieved and I am expressing that grief via a metaphor. Likewise, if I say "I stood in line for a million years" I am using an exaggeration to communicate another literal meaning: I waited a long time. Indeed, more often than not, metaphor is exactly the right vehicle for conveying a literal meaning and is far better than nonfigurative language. The shortest distance between two minds is a figure of speech. -- Making Senses of Scripture
The literal sense of the author was "creation is the orderly act of a loving Creator God." What the modern reader often hears, however, is "The universe was made in six 24-hour days." This is as wrong-headed as taking me to mean I actually stood in line a million years or that my cardiac tissue has been torn in half or that Christ had delusions of being a grape plant.-- Making Senses of Scripture
