To justify Christian morality because it provides a foundation of morality, instead of showing the necessity of Christian morality from the truth of Christianity, is a very dangerous inversion.
The first and last lesson of religion is, "The things that are seen, are temporal; the things that are unseen, are eternal." It puts an affront upon nature.
A large stone presented by the archangel Gabriel to the patriarch Abraham, and preserved at Mecca. The patriarch had perhaps asked the archangel for bread.
If 'god' is a metaphysical term, then it cannot be even probable that a god exists. For to say that 'God exists' is to make a metaphysical utterance which cannot be either true or false. And by the same criterion, no sentence which purports to describe the nature of a transcendent god can possess any literal significance.
The secularists have not wrecked divine things; but the secularists have wrecked secular things, if that is any comfort to them. The Titans did not scale heaven; but they laid waste the world.
