Protestantism has prospered just in proportion as she has kept the cross at the forefront of all her preaching. The missionaries bring back the same report from every field, that it is the story of Jesus' death that opens the hearts of the pagan world. Every now and then a denomination has started, determined to get rid of the cross of Jesus, or at least to pay scant attention to it, and in every case these denominations have been at the end of the third or fourth generation either decaying or dead. There is no interpretation of the Christian religion that has in it redeeming power which ignores or belittles the death of Christ.

If Protestantism to-day is not doing what it ought to do, and is manifesting symptoms which are alarming to Christian leaders, it is because she has in these recent years been engaged so largely in practical duties as to forget to drink inspiration from the great doctrines which must forever furnish life and strength and hope. If you will allow me to prophesy this morning, I predict that the preaching of the next fifty years will be far more doctrinal than the preaching of the last fifty years has been. I imagine some of you will shudder at that. You say you do not like doctrinal preaching, you want preaching that is practical. Well, pray, what is practical preaching? Practical preaching is preaching that accomplishes the object for which preaching is done, and the primary object of all Christian preaching is to reconcile men to God. The experience of 1900 years proves that it is only doctrinal preaching that reconciles the heart to God. If, then, you really want practical preaching, the only preaching that is deserving the name is preaching that deals with the great Christian doctrines. But somebody says, I do not like doctrinal preaching. A great many people have said that within recent years. I do not believe they mean what they say. They are not expressing with accuracy what is in their mind. They do like doctrinal preaching if they are intelligent, faithful Christians, for doctrinal preaching is bread to hearts that have been born again. When people say they do not like doctrinal preaching, they often mean that they do not like preaching which belongs to the eighteenth or seventeenth or sixteenth centuries. They are not to be blamed for this. There is nothing that gets stale so soon as preaching. We can not live upon the preaching of a bygone age. If preachers bring out the interpretations and phraseology which were current a hundred years ago, people must of necessity say, "Oh, please do not give us that, we do not like such doctrinal preaching." But doctrinal preaching need not be antiquated or belated, it may be fresh, it may be couched in the language in which men were born, it may use for its illustrations the images and figures and analogies which are uppermost in men's imagination. And whenever it does this there is no preaching which is so thrilling and uplifting and mighty as the preaching which deals with the great fundamental doctrines.

In one sense, the Christian religion never changes, in another sense it is changing all the time. The facts of Christianity never change, the interpretations of those facts alter from age to age. It is with religion as it is with, the stars, the stars never change. They move in their orbits in our night sky as they moved in the night sky of Abraham when he left his old Chaldean home. The constellations were the same at the opening of our century as they were when David watched his flocks on the old Judean hills. But the interpretations of the stars have always changed, must always change. Pick up the old charts which the astrologers made and compare them with the charts of astronomers of our day. How vast the difference! Listen to our astronomers talk about the magnitudes and disunites and composition of the stars, and compare with their story that which was written in the astronomy of a few centuries ago. The stellar universe has not changed, but men's conceptions have changed amazingly. The facts of the human body do not change. Our heart beats as the heart of Homer beat, our blood flows as the blood of Julius Caesar flowed, our muscles and nerves live and die as the nerves and muscles have lived and died in the bodies of men in all the generations—and yet, how the theories of medicine have been altered from time to time. A doctor does not want to hear a medical lecturer speak who persists in using the phraseology and conceptions which were accepted by the medical science of fifty years ago. Conceptions become too narrow to fit the growing mind of the world, and when once outgrown they must be thrown aside. As it is in science, so it is in religion. The facts of Christianity never change, they are fixt stars in the firmament of moral truth. Forever and forever it will be true that Christ died for our sins, but the interpretations of this fact must be determined by the intelligence of the age. Men will never be content with simple facts, they must go behind them to find out an explanation of them. Man is a rational being, he must think, he will not sit down calmly in front of a fact and be content with looking it in the face, he will go behind it and ask how came it to be and what are its relations to other facts. That is what man has always been doing with the facts of the Christian revelation, he has been going behind them and bringing out interpretations which will account for them. The interpretations are good for a little while, and then they are outgrown and cast aside.

A good illustration of the progressive nature of theology is found in the doctrine of the atonement. All of the apostles taught distinctly that Christ died for our sins. The early Christians did not attempt to go behind that fact, but by and by men began to attempt explanations. In the second century a man by the name of Irenaeus seized upon the word "ransom" in the sentence, "The Son of man is come to give his life a ransom for many," and found in that word "ransom" the key-word of the whole problem. The explanation of Irenaeus was taken up in the third century by a distinguished preacher, Origen. And in the fourth century the teaching of Origen was elaborated by Gregory of Nyssa.

According to the interpretation of these men, Jesus was the price paid for the redemption of men. Paul frequently used the word redemption, and the word had definite meanings to people who lived in the first four centuries of the Christian era. If Christ was indeed a ransom, the question naturally arose, who paid the price? The answer was, God. A ransom must be paid to somebody—to whom was this ransom paid? The answer was, the devil. According to Origen and to Gregory, God paid the devil the life of Jesus in order that the devil might let humanity go free. The devil, by deceit, had tricked man, and man had become his slave—God now plays a trick upon the devil, and by offering him the life of Jesus, secures the release of man. That was the interpretation held by many theologians for almost a thousand years, but in the eleventh century there arose a man who was not satisfied with the old interpretation. The world had outgrown it. To many it seemed ridiculous, to some it seemed blasphemous. There was an Italian by the name of Anselm who was an earnest student of the Scriptures, and he seized upon the word "debt" as the key-word of the problem. He wrote a book, one of the epoch-making books of Christendom, which he called "Cur Deus Homo." In this book Anselm elaborated his interpretation of the reconciliation. "Sin," he said, "is debt, and sin against an infinite being is an infinite debt. A finite being can not pay an infinite debt, hence an infinite being must become man in order that the debt may be paid. The Son of God, therefore, assumes the form of man, and by his sufferings on the cross pays the debt which allows humanity to go free." The interpretation was an advance upon that of Origen and Gregory, but it was not final. It was repudiated by men of the twelfth and thirteenth centuries, and finally, in the day of the Reformation, it was either modified or cast away altogether.

Martin Luther, Calvin, and the other reformers seized upon the word "propitiation," and made that the starting-point of their interpretation. According to these men, God is a great governor and man has broken the divine law—transgressors must be punished—if the man who breaks the law is not punished, somebody else must be punished in his stead. The Son of God, therefore, comes to earth to suffer in His person the punishment that rightly belongs to sinners. He is not guilty, but the sins of humanity are imputed to Him, and God wreaks upon Him the penalty which rightfully should have fallen on the heads of sinners. That is known as "the penal substitution theory."

It was not altogether satisfactory, many men revolted from it, and in the seventeenth century a Dutchman, Hugo Grotius, a lawyer, brought forth another interpretation, which is known in theology as "the governmental theory." He would not admit that Christ was punished. His sufferings were not penal, but illustrative. "God is the moral governor," said Grotius, "his government must be maintained, law can not be broken with impunity. Unless sin is punished the dignity of God's government would be destroyed. Therefore, that man may see how hot is God's displeasure against sin, Christ comes into the world and suffers the consequences of the transgressions of the race. The cross is an exhibition of what God thinks of sin." That governmental theory was carried into England and became the established doctrine of the English Church for almost three hundred years. It was carried across the ocean and became the dominant theory in the New Haven school of theologians, as represented by Jonathan Edwards, Dwight, and Taylor. The Princeton school of theology still clung to the penal substitution theory, and it was the clashing of the New Haven school and the Princeton school which caused such a commotion in the Presbyterian Church of sixty years ago. They are antiquated. They are too little. They seem mechanical, artificial, trivial. We can say of the governmental theory what Dr. Hodge said, "It degrades the work of Christ to the level of a governmental contrivance." If I should attempt to preach to you the governmental theory as it was preached by theologians fifty years ago, you would not be interested in it There is nothing in you that would respond to it. You would simply say, "I do not like doctrinal preaching." Or if I should go back and take up the penal substitution theory in all its nakedness and hideousness, and attempt to give it to you as the correct interpretation of the gospel, you would rise up in open rebellion and say, "We will not listen to such preaching." If I should go back and take up the Anselmic theory and attempt to show how an infinite debt must be paid by infinite suffering, you would say: "Stop, you are converting God into a Shylock, who is demanding His pound of flesh. We prefer to think of Him as our heavenly Father." If I should go further back and take up the old ransom theory of Origen and Gregory, I suspect that some of you would want to laugh. You could not accept an interpretation which represents God as playing a trick upon Satan in order to get humanity out of his grasp. No, those theories have all been outgrown. We have come out into larger and grander times. We have higher conceptions of the Almighty than the ancients ever had. We see far deeper into the Christian revelation than Martin Luther or John Calvin ever saw. These old interpretations are simply husks, and men and women will not listen to the preaching of them. If, now and then, a belated preacher attempts to preach them, the people say, "If that is doctrinal preaching, please give us something practical."

And so the Church is to-day slowly working out a new interpretation of the great fact that Christ died for our sins. The interpretation has not yet been completed, and will not be for many years. I should like this morning simply to outline in a general way some of the more prominent features of the new interpretation. The Holy Ghost is at work. He is taking the things of Christ and showing them unto us. The interpretation of the reconciliation of the future will be superior in every point to any of the interpretations of the past.

The new interpretation is going to be simple, straightforward, and natural. The death of Christ is not going to be made something artificial, mechanical, or theatrical. It is going to be the natural conception of the outflowing life of God.

The new interpretation is going to start from the Fatherhood of God. The old theories were all born in the counting-room, or the court-house. Jesus went into the house to find His illustrations for the conduct of the heavenly Father. He never went into the court-house, nor can we go there for analogies with which to image forth His dealings with our race. It was His custom to say, "If you, being evil, know how to give good gifts unto your children, how much more shall your Father which is in heaven give good things to them that ask him."
