Often he complained to his friends about the terrors of the struggles which the Devil caused him. "He has never since the creation been so fierce and angry as now at the end of the world. I feel him very plainly. He sleeps closer to me than my Käthe--that is, he gives me more trouble than she does pleasure." Luther never tired of censuring the pope as the Anti-Christ, and the papal system as the work of the Devil. But a closer scrutiny will recognize under this hatred of the Devil an indestructible piety, in which the loyal heart of the man was bound to the old Church. What became hallucinations to him were often only pious remembrances from his youth, which stood in startling contrast to the transformations which he had passed through as a man. For no man is entirely transformed by the great thoughts and deeds of his manhood. We ourselves do not become new through new deeds. Our mental life is based upon the sum of all thoughts and feelings that we have ever had. Whoever is chosen by Fate to establish new greatness by destroying the greatness of the old, shatters in fragments at the same time a portion of his own life. He must break obligations in order to fulfil greater obligations. The more conscientious he is, the more deeply he feels in his own heart the wound he has inflicted upon the order of the world. That is the secret sorrow, the regret, of every great historical character. There are few mortals who have felt this sorrow so deeply as Luther. And what is great in him is the fact that such sorrow never kept him from the boldest action. To us this appears as a tragic touch in his spiritual life.
