Theology might justly be defined the science of contradictions. Every religion is only a system, invented to reconcile irreconcilable notions. By the aid of habit and terror, man becomes obstinate in the greatest absurdities, even after they are exposed in the clearest manner. All religions are easily combated, but with difficulty extirpated. Reason avails nothing against custom, which becomes, says the proverb, a second nature. Many persons, in other respects sensible, even after having examined the rotten foundation of their belief, adhere to it in contempt of the most striking arguments. Whenever we complain of religion, its shocking absurdities, and impossibilities, we are told that we are not made to understand the truths of religion; that reason goes astray, and is capable of leading us to perdition; and moreover, that what is folly in the eyes of man, is wisdom in the eyes of God, to whom nothing is impossible. In short, to surmount, by a single word, the most insurmountable difficulties, presented on all sides by theology, they get rid of them by saying, these are mysteries!
