here to appreciate the importance of the Reformation; I have done it, partially, elsewhere, and hope to return to it in future. Suffice it to say that the revolution which goes by this name wrought an upheaval in the political, social and religious structure of Europe and prepared the ground for our modern civilization.

No man in history has more thoroughly represented and more completely dominated his time. And these earliest years were the most beautiful in his life; a desperate battle and a momentous victory for progress and for the right. There have been more faultless men than Luther, but there have been none who have
