"'Those who are generally termed Rationalists,' says Dr. Bretschneider, 'admit universally, in Christianity, a divine, benevolent, and positive appointment for the good of mankind, and Jesus as a Messenger of divine Providence, believing that the true and everlasting word of God is contained in the Holy Scripture, and that by the same the welfare of mankind will be obtained and extended. But they deny therein a supernatural and miraculous working of God, and consider the object of Christianity to be that of introducing into the world such a religion as reason can comprehend; and they distinguish the essential from the unessential, and what is local and temporary from that which is universal and permanent in Christianity.' There is, however, a third class of divines, which in fact differs very little from this, though very widely in profession. They affect to allow 'a revealing operation of God,' but establish on internal proofs rather than on miracles the divine nature of Christianity. They allow that revelation _may_ contain much out of the power of reason to explain, but say that it should assert nothing contrary to reason, but rather what may be proved by it. This sounds better, but they who are acquainted with the writings of the persons thus described, know that by establishing Christianity on internal proofs, they only mean the accepting those doctrines which they like, and which seem to them _reasonable_, and that though they allow in theory that revelation may contain what are technically called much above reason, yet in practice they reject the positive doctrines of Christianity (I mean especially the doctrines of the Trinity, the Atonement, the Mediation and Intercession of our Lord, Original Sin, and Justification by Faith), because they allege that those doctrines are contrary to reason. The difference between them and the others is therefore simply this, that while the others set no limits at all to the powers of reason in matters of faith, they set such a limit in theory but not in practice, and consequently cannot justly demand to be separated from the others."[6] One of the ablest advocates of Supernaturalism among English divines is the late Dr. A. McCaul, of London. He joins issue successfully with the Rationalists. We quote a specimen of his method of argument. His definition of Rationalism is beautifully lucid and logical. He says:
