Creation and Creationism.
Creation, then, does not make any difference to things. If you like, it makes all the difference, but you cannot expect to find a ‘created look’ about things. The effect of creation is just that things are there, being themselves, instead of nothing. Creation is, of course, an unintelligible notion. I mean it is unintelligible in the sense that God is unintelligible. It is a mystery. Not that the notion is self-contradictory, but it involves extrapolating from what we can understand to what we are only trying to understand. To be created is to exist instead of nothing; but the notion of ‘nothing’ is itself a mystery unintelligible to us.
Unless we grasp the truth that creation means leaving the world to be itself, to run itself by its own scientific laws so that things behave in accordance with their own natures and not at the arbitrary behest of some god, we shall never begin to understand that the Lord we worship is not a god but the unknown reason why there is anything instead of nothing. –Herbert McCabe, God Still Matters.
