The only legitimate method of controverting a doctrine which purports to be founded on the Scriptures is the exegetical. If its advocates undertake to show that it is taught in the Bible, its opponents are bound to prove that the Bible, understood agreeably to the recognized laws of interpretation, does not teach it. This method, comparatively speaking, is little relied upon, or resorted to by the adversaries of the Church doctrine concerning the satisfaction of Christ. Their main reliance is on objections of two classes: the one drawn from speculative or philosophical principles; the other from the sentiments or feelings. It is not uncommon for modern writers, especially among the German theologians, to begin the discussion of this subject by a review of the Scriptural statements in relation to it. This is often eminently satisfactory. It is admitted that Christ saves us as a priest by offering Himself a sacrifice for sin; that He is a priest and sin offering in the Old Testament sense of those terms; and that a priest is a mediator, a representative of the people, and an offerer of sacrifices. It is admitted that the sin offerings of the old dispensation were expiatory sacrifices, designed to satisfy the justice of God and to secure the restoration of his favour to the sinner. It is admitted that expiation was made by substitution and vicarious punishment, that the victim bore the sins of the offerer and died not only for his benefit, but in his place. It is further admitted that all this was designed to be typical of the priesthood and sacrifice of Christ, and that the New Testament teaches that these types were fulfilled in Him; that He was the only true priest, and his offering of Himself was the only available sacrifice for sin; that He bore the sins of men; made expiation for their guilt by taking their place, and sustaining the penalty of the law and time wrath of God in their stead; and that the effect of his satisfaction of justice is that God is in such a sense reconciled to man, that He can consistently pardon their sins, and bestow upon them all saving blessings. Having given this exhibition of what the Scriptures teach on the subject, they go on to state what the Fathers taught; how the doctrine was presented during the Middle Ages, and afterwards by the Reformers; how the Rationalists and Supernaturalists of the last generation dealt with it; and how the modern speculative theologians have philosophized about it; and end, generally, by giving in their adhesion to some one of these modern theories more or less modified. All the while there stand the Scriptural statements untouched and unrefuted. They are allowed to go for what they are worth; but they are not permitted to control the writers own convictions. This course is adopted by different men on different principles. Sometimes it is upon the distinct denial of the inspiration of the sacred writers. They are admitted to be honest end faithful. They may or may not have been the recipients of a supernatural revelation, but they were fallible men, subject to all the influences which determine the modes of thought and the expressions of the men of any given age or nation. The sacred writers were Jews, and accustomed to a religion which had priests and sacrifices. It was, therefore, natural that they should set forth under figures and in the use of terms, borrowed from their own institutions, the truths that Christ saved sinners, and that in the prosecution of that work He suffered and died. These truths may be retained, but the form in which they are presented in the Bible may be safely discarded.
Others, and perhaps the majority of the most popular of this class of theologians, go further than this. They are willing that criticism and forced interpretations should make what havoc they please with the Bible. Any and every book may be rejected from the canon. Any and every doctrine may be interpreted out of the sacred pages; still the only Christianity they value is safe. Christianity is independent of any form of doctrine. It is a life, an inward, organic power, which remodels the soul; which life is Christianity, because it is assumed to have its origin in Christ.
Others again act on the principles of that form of rationalism which has received the name of Dogmatism. The doctrines and facts of the Bible are allowed to stand as true. They are allowed to be the proper modes of statement for popular instruction and impression. But it is assumed to be the office of the theologian to discover, present, and bring into harmony with his system, the philosophical truths which underlie these doctrinal statements of the Bible. And these philosophical truths are assumed to be the substance of the Scriptural doctrines, of which the doctrines themselves are the unessential and mutable forms. Thus the doctrine of the Trinity is admitted. The form in which it is presented in the Bible is regarded as its popular form, which it may be useful to retain for the people. But the real and important truth which it involves is, that original, unintelligent, unconscious Being (the Father) comes to conscious existence in the world (the Son), by an eternal process, and returns by an unceasing flow into the infinite (the Spirit). It is also admitted that God became flesh, but it was, as some say, in the whole race of man; mankind are the manifestation of God in the flesh; or, as others say, the Church is his body, that is, the form in which the incarnation is realized. Christ is acknowledged to be our saviour from sin, but it is by a purely subjective process. He introduces a new life power into humanity, which enters into conflict with the evil of our nature, and after a painful struggle overcomes it. This is called the application of philosophy to the explanation of Scriptural doctrines. It is patent, however, that this is not explanation, but substitution. It is the substitution of the human for the divine; of the thoughts of men, which are mere vapour, for the thoughts of God, which are eternal verities. It is giving a stone for bread, and a scorpion for an egg. It is, indeed, a very convenient method of getting rid of the teachings of the Bible, while professing to admit its authority. It is important, however, to notice the concession involved in these modes of proceeding. It is acknowledged that the Church doctrine of a true expiatory sacrifice for sin, of a real satisfaction of justice by means of the vicarious punishment of sin, is the doctrine of the Scriptures, as well of the Old Testament as of the New. This is all we contend for, and all we care for. If God teaches this, men may teach what they please.
