The work of Erasmus reached Wittenberg in September, 1524. Luther treated it with contempt and ostentatiously repudiated it. He wrote to Spalatin, on November 1, that it disgusted him; he had been able to read only two pages of it; it was tedious to him to reply to so unlearned a book by so learned a man.[745] All the same, he did write a lengthy and detailed answer; that he delayed doing so until late in the following year is to be accounted for by the Peasant-War with its terrors, which entirely engrossed his attention; it was also the year of his marriage. In estimating the value of the reply, upon which he then set to work with great energy, we must bear in mind the state of the author and the inward and outward experiences through which he had just gone. The impression made on his mind by the events of those days has left its stamp in the even more than usually extreme utterances contained in his reply to Erasmus. When once he had begun the work he carried it to its end with a rush; he himself admits that it was composed in excessive haste. We also know to whose influence his final decision to take the work in hand was due, viz. to Catherine Bora. “It was only at her request” that he undertook the work, when she pointed out to him, “that his foes might see in his obstinate silence an admission of defeat.”[746] _Luther’s Book “On the Enslaved Will” against Erasmus_ The title “_De servo arbitrio_,” “On the enslaved will,” was borrowed by Luther from a misunderstood saying of St. Augustine’s.[747] While the book which bears it was still in the press his friend Jonas commenced a German version and entitled it: “Dass der freie Wille nichts sei.”[748] However grotesque and exaggerated some of the principal theses of the famous work, Luther was at pains to declare therein that they were the result of most careful deliberation and were not written in the heat of controversy. Hence, as a Protestant historian says, “we must not seek to hide or explain them away, as was soon done by Luther’s followers and has been attempted even in our own day.”[749] Another Protestant scholar, in the preface to his study on the work “_De servo arbitrio_,” remarks that “quite rightly it caused great scandal and wonder,” and goes on to point out that “the hard, offensive theory” which it champions was “no mere result of haste or of annoyance with Erasmus, coupled with the desire clearly to define his own position with regard to the latter,” but really “expresses the matured conviction of the Reformer.”[750]
