On the part of the Elector, Luther still continued to reap the benefit of that placid good-will which disregarded all attempts, either by friendly words or menaces, to set that prince against him. Luther for this thanked him publicly, without meeting with any demurrer from the Elector, as well in a dedication of the first part of his new work on the Psalms, which he had sent to the press early in 1519, as in another prefixed to his tract on Christian comfort, already noticed. This last work he had been encouraged to write by Spalatin, the confidant of the sick prince whom it was intended to please. In the dedication prefixed to the Psalms, he expressed his joy at hearing how Frederick had declared in a conversation reported by Staupitz, that all sermons, made by man's wit and uttering man's opinions, were cold and powerless, and the Scriptures alone inspired with such marvellous power and majesty that one must needs say, 'There is something more there than mere Scribe and Pharisee; there is the finger of God;' and how, when Staupitz had concurred in the remark, the prince had taken his hand and said, 'Promise me that you will always think thus.' Luther also thanked Frederick for having, as all his subjects knew, taken more care of his safety than he had done himself. In his thoughtlessness, he himself had thrown the die, and had already prepared himself for the worst, and only hoped to be able to retire into some corner, when his prince had come forward as his champion. At the same time the Elector remained constant in his efforts to check the impetuosity of Luther. We have noticed how he encouraged him, through Spalatin, to peaceful work in the service of Christian preaching. When the episcopal missive from Stolpen threatened to make the storm break out afresh, he sent, by Spalatin, an urgent exhortation to Luther to restrain his pen, and further advised him to send letters of explanation, in a conciliatory spirit, to Albert, Archbishop of Magdeburg and Mayence, and the Bishop of Merseburg. Luther wrote to both in a tone of perfect dignity. He begged them not to lend an ear to the complaints and calumniations which were being circulated against him, especially in reference to giving the cup to the laity, and to the Papal power, until the matter had been seriously examined. He spoke at the same time of malicious accusers, who on those points held secretly the same opinions as himself.
