Rationalism was very adroit in its initial steps. Its method of betrayal was, Judas-like, to sit in friendly intercourse beside its victim, and afterwards, when the fulness of malevolent inspiration had come, to give the fatal kiss in the presence of enemies. The people did not know the ills they were about to suffer until deliverance was well-nigh hopeless. Had Rationalism begun by laying down its platform and planning the work of proof, the forces of the opposition might have been organized. But it commenced without a platform, and worked long without one. The systematic theology of Bretschneider would by no means be accepted by the entire class of Rationalistic divines. To get a fair conception of what has been the aggregate sentiment of the whole class, one must wander through hundreds of volumes of exegesis, history, philosophy, and romance; and these covering a space of many years. Even when you hold up your treasure, and cry "Eureka!" your shrewd opponent will coolly say that you have given a false interpretation, and have drawn wrong conclusions,—that his masters never claimed such an absurdity. Rationalism looked upon Revelation as a tottering edifice, and set itself busily at work to destroy the entire superstructure. But sometimes it is the surrounding vines and trees that shake in the autumn storm, and not the building itself; and often beneath the worm-eaten bark there is a great oaken heart, which no arm is strong enough and no axe sufficiently keen to cleave.
Rationalism has been striving to destroy a house which was built upon a rock; and if it fell not, the fault lay not in the absence of ingenuity and strength of attack, but in the undecayed material and deeply-grounded solidity of the structure.
We are not blind to the extenuating circumstances that are adduced for Rationalism. The motives of its founders seemed pure enough, for these men held their life-task to be the purification of faith from the misconceptions of inspiration, and the deliverance of the church from the thraldom of stiff formularies. Some of their successors held that their labors were only philosophical, and hence could not affect theology. They all claimed relationship with the Reformers, and with the good and great of all ages. Bretschneider says that Luther talked of miracles as only fit for the ignorant and vulgar, as apples and pears are for children.
Paulus tries to prove the great Saxon a Rationalist by the following circumstance. The Elector of Brandenburg having asked Luther if it were true that he had said he should not stop unless convinced from Scripture, received this reply: "Yes, my lord, unless I am convinced by clear and evident reasons!" It was a favorite view of the Rationalists that the Reformation had been produced by Reason asserting her rights; and it was then an easy step to take, when they claimed as much right to use Reason within the domain of Protestantism as their fathers possessed when within the pale of Catholicism.
But there were wide points of difference between the Reformers and Rationalists. The former would return to the spirit and letter of the Word of God, while the latter did not hesitate to depart from both. The former accepted the Bible as it is, making Faith its interpreter; the latter would only construe its utterances as Reason would dictate.
With the Reformers there was a conflict between the Bible and the Roman church, but harmony between Reason and the Bible; hence these two homogeneous elements should be united and the rebellious one forever discarded. But with the Rationalists there was an irreconcilable difference between Reason and Revelation, and the latter must be moulded into whatever shape the former chose to mark out. The Reformers celebrated the reunion of both; but the Rationalists never rested as long as there was any hope of putting asunder those whom they believed God had never joined together. But the later Rationalists, least of all, could claim consanguinity with the Reformers. How could they who banished miracles from the Scriptures and reduced Christ to a much lower personality than even the Ebionites declared him to be, dare to range themselves in the circle of the honored ones who had unsealed the long-locked treasures of inspiration, and declared that Christ, instead of being an inferior Socrates, was divine, and the only worthy mediator between God and man? After we accept every reasonable apology for this destructive skepticism there will still be found a large balance against it. There are four considerations which must always be borne in mind when we would decide on the character of any development of religious doubt and innovation. 1. The necessity for its origin and development; 2. Its point of attack; 3. The spirit with which it conducts its warfare; and 4. The success which it achieves.
Let us see how Rationalism stands the test of these criteria. It must be confessed that the German Protestant church, both the Lutheran and Reformed, called loudly for reinvigoration. But it was Faith, not Reason, that could furnish the remedy. The Pietistic influence was gaining ground and fast achieving a good work; but it was reprobated by the idolaters of Reason, and the tender plant was touched by the fatal frost. Had Pietism, with all its extravagances, been fostered by the intellect of the pulpits and universities it would have accomplished the same work for Germany in the seventeenth that the Wesleys and Whitefield wrought in England in the eighteenth century. There was no call for Rationalism, though its literary contributions to the church and the times will eventually be highly useful; but they were ill-timed in that season of remarkable religious doubt. It was the warmth of the heart, and not the cold logic of the intellect that could rejuvenate the church.
Nor do we find the position of Rationalism to be any better when we call to mind that it really acknowledges no hallowed ground. It attacked the most endeared doctrines of our faith, and applied its enginery to those very parts of our citadel which we would be most likely to defend the longest. Had it contented itself with the mere discussion of minor points, with here and there a quibble about a miracle or a prophecy, we could excuse many of its vagaries on the score of enthusiasm. But its premiss was, "We will accept nothing between the two lids of this Book if our Reason cannot fathom it." Hence, all truth, every book of the Bible, even the sacraments of the church, came in for their share of discussion and pruning. In this respect Rationalism takes rank as one of the most corrupt tendencies of infidelity which appears anywhere upon the page of ecclesiastical history. But do we find its spirit mild and amiable? Some of the Rationalists were naturally men of admirable temperament, but this was no effect of their faith. The most lamentable feature of this whole system was the ruthless character of its warfare. The professions of love for the Scriptures and the church, which we so often meet with in the writings of the early Rationalistic divines, were soon laid aside. The demon of destruction presided over the storm. And the work of ruin was rapid, by forced marches and through devious paths,—in the true military style. When the hour of fight came there was no swerving. Men full of the spirit of a bad cause will sometimes fight as valiantly as others for a good one; but it is then that God determines the victor. The evangelical Christians of Protestant Germany saw their banner captured by their foes. And it was their foes who gave the first fire; but they will not be so fortunate in the last encounter. We challenge Deism and even Atheism itself, to furnish proof of a more malignant antipathy to some of the cardinal doctrines of the common faith of Christendom than Rationalism has produced in certain ones of its exponents, and which we shall strive to expose in future pages of this work. Some of the Rationalists were John-like in all they did, save when they discussed the holy truths of inspiration. Then they were possessed by the evil spirit. Nowhere can we find a more deplorable example of the disastrous effects of a false creed on the human character. It is an infallible law of our nature that the mind, not less than the body, becomes depraved by an impure diet. Many persons have been permanently injured by reading the Briefe über den Rationalismus, and other works which Rationalism has published against the doctrines of Revelation.
As far as the completeness and speed of the work of Rationalism are concerned we shall find that it ranks with the most rapid and destructive errors that have ever risen in conflict with the church. Instead of striving to build up a land that had so long been cursed with the blight of Papacy, and had not yet been redeemed a full century, this evil brought its quota of poison into the university, the pulpit, and the household circle. Nor did it cease, as we shall see, until it corrupted nearly all the land for several generations. To-day the humblest peasant who steps on our shore at Castle Garden will stare in wonder as you speak of the final judgment, the immortality of the soul, and the authenticity of the Scriptures. Naturalism could not live thus long in Italy, nor Deism in England, nor the blind Atheism of the Encyclopædists in France; neither in either land was the work of destruction so complete.
But the church has proved herself able to depose many corruptions of her faith; yet this attack upon her faith she has still to vanquish thoroughly. It is not works on the evidences of Christianity that she needs for the consummation of her great aim; and we trust that, by the divine blessing, the inquiry into the vagaries of Reason upon which we are now entering will not be without its effect upon the young mind of America. Our task is simply to lift the finger of warning against the increasing influx of Rationalistic tendencies from France and England; which lands had first received them from Germany. One of our great dangers lies in permitting Reason to take our premises and build her own conclusions upon them. There is an intimate union between theology and philosophy; and anything less than the pursuit and cultivation of a sound philosophy will endanger our theology. Tennyson gives a beautiful word of advice when he says:
