It is a metaphor.

Really? The burnt offerings in the Old Testament were metaphors?
Was the ram that Abraham and Isaac offered as a burnt offering in Genesis 22 (after God allowed Isaac to be spared) a metaphor?
Was Creation a metaphor?
What about the Flood, was that a metaphor?
It's disturbing to watch what happens when people deny the teachings of the Church and opt for their own personal interpretations. EVERYTHING they don't like gets dismissed as either a metaphor or outdated. Modern moral relativism/secular humanism certainly got its start during the Reformation.
