Recent historical investigation emphasizes more and more that the movement was not religious in any sense, except superficially, and that the forces that gathered behind Luther were political. There was the opportunity for reigning princes to become both the head of the Church and the State in their dominions and, above all, to get possession of the property of the Church and share it with the nobility or creatures of their own, thus strengthening their hold upon the government and securing extension of power. We know in our day the all-persuasive power of political graft and how it saps honesty and corrupts character. Everywhere the track of it can be followed readily in the Reformation period. Luther was not only the first but the most important of these reformers. There has been more controversy over the true import of his work than that of any of the others. He was undoubtedly the leader through whom the religious revolution of this period was brought about. He had had predecessors, but the work of none of them had anything like the significance of his. Within the past ten years his history has been revolutionized. Denifle, the great historian of the mediaeval universities, by publishing all the documents that show the worse side of Luther's character created a great commotion in Germany. Grisar's later life of the reformer is, in accordance with the traditions of his order, much more irenic, yet makes it very clear how many of the very generally accepted favorable impressions with regard to Luther are contradicted by the many lately unearthed materials with regard to his life now available. Only those who have read these books can have any pretence to know the realities of the history of the religious revolt in Germany, though even these probably must not be considered as representing ultimate truth. With regard to Luther and the other reformers, as well as the significance of the whole movement, I have preferred to quote only Protestant authorities in order to avoid the almost inevitable bias of my own educational training and {249} environment. Even thus I can only hope to give an approximately impartial discussion of these men whose work as I see it did more to hurt human development in every line of thought than anything else in modern history.
