What does it mean to be a human being? What are we really?
The answer our children are taught in school is that we are just animals, the result of a long process of accidents in which an amoeba became a fish, became a lizard, became a monkey, became us. So all we are is a material body, a fluke of the universe, a "selfish gene," and when we die, that's it.
Of course, virtually no one can or does live consistently with this "materialist" view of human beings. Even radical atheists like Richard Dawkins get "mad" at Christians for the supposed "wrong" things they do. But getting "mad" and moral concepts like "right" and "wrong" make no sense if we are simply material beings, biological robots.
Jesus Christ, and before him all the prophets of Israel, emphatically renounced the view that all we are is animals. The readings for this Sunday point relentlessly to the fact that we are something more: spiritual beings, personal beings, made for communion with God and eternal life.
