Writers in defence of Christianity had, before Butler, amply discussed the several departments of evidences; but still there remained objections. The structure of the globe, the course of nature, the organization of animals, &c. were affirmed to contradict revelation. Its doctrines and duties, moreover, were pronounced inconsistent with sound reason. Butler repeats none of the old arguments, but confines himself to the showing that the declarations of revelation are in perfect harmony with facts seen daily in the world, and which all admit. That the world might not have been ordered and governed otherwise, he does not choose to dispute. Taking things as they are, and closely studying the connection between one thing and another, we ought to inquire what course of action on our part, will conform to the needs of such a nature and such circumstances. Our bodies are constructed of parts, all adapted to each other, and also to one general end. So too, our souls. And the two together have relations and adaptations, which may, to some extent at least, indicate what is designed to be the _general_ end of our existence. If Christianity befits these several parts of our mixed nature and their obvious uses, then there is nothing incongruous between the two; and no objections against Christianity can be drawn from the course of nature. On the contrary, all seems to be governed as the gospel declares it is, and shows that the Author of man and the Author of the Bible is the same. This is still more impressive when we consider that we have a _moral faculty_; for it is the very object and business of this faculty to deal with right and wrong, good and evil; the facts and magnitudes of which are obvious in the course of nature. If Christianity does, in an especial manner, _befit_ this faculty, if it is adapted to promote our general rectitude and happiness, and if it contains no principle which is not discernible in the government of the visible world, then there is no discrepancy between Christianity and Providence. This is Butler’s position. He confines himself to proving such an analogy between revelation and the daily course of things, as that nothing known in the universe can be offered in disproof of Christianity. The mode of warfare was new. Without professing to prove Christianity to be true, he demonstrates that it cannot be proved to be false; and that if it be even probable, the rejection of it is a gross folly and a tremendous hazard. Every objection against it he proves to be equally forcible against facts which constantly occur, and which all admit, though none profess to understand. Thus leaving the ramparts of the church to be guarded by the mighty men who had valiantly maintained its defence, he quietly walked out into the camp of the enemy, and spiked every gun!
