Luther had foreseen that the cause of the Reformation would soon be brought before the new emperor; and, when Charles was still at Madrid, addressed a letter to him, in which he said, "If the cause which I defend is worthy of being presented before the heavenly Majesty, it cannot be unworthy of engaging the attention of a prince of this world. O, Charles! prince of the kings of the earth, I cast myself as a suppliant at the feet of your most serene majesty, and beseech you to deign to take under the shadow of your wings, not me, but the very cause of eternal truth, for the defence of which God has entrusted you with the sword."[177] The young king of Spain threw aside this odd letter from a German monk, and returned no answer. [177] Causam ipsam veritatis.... (L. Ep. i, p. 392. 15th Jan., 1520.) While Luther was turning in vain toward Madrid, the storm seemed gathering around him. Fanaticism was rekindled in Germany. Hochstraten, indefatigable in his efforts at persecution, had extracted certain theses from Luther's writings, and obtained their condemnation by the universities of Cologne and Louvain. That of Erfurt, which had always had a grudge at Luther, for having given Wittemberg the preference, was on the eve of following their example. But the doctor, having been informed of it, wrote Lange, in terms so energetic that the theologians of Erfurt took fright, and said nothing. Still, however, there was enough to inflame the minds of men in the condemnation pronounced by Cologne and Louvain. More than this; the priests of Misnia who had espoused Emser's quarrel said openly (such is Melancthon's statement) that there would be no sin in killing Luther.[178] "The time is come," said Luther, "when men think they will do Jesus Christ service by putting us to death." The murderous language of the priests did not fail of its effect. [178] "Ut sine peccato esse eum censebant qui me interfecerit." (L. Ep. i, p. 383.) [Sidenote: FREDERICK'S INSTRUCTIONS TO HIS ENVOY.] "One day," says a biographer, "when Luther was in front of the Augustin convent, a stranger, with a pistol hid under his arm, accosted him, and said, Why do you walk about thus quite alone?" "I am in the hands of God," replied Luther; "He is my strength and my shield." "Thereupon," adds the biographer, "the stranger grew pale, and fled trembling."[179] About the same time Serra Longa, the orator of the conference of Augsburg, wrote to the Elector, "Let not Luther find any asylum in the states of your highness, but, repulsed by all, let him be stoned to death in the face of heaven. This would please me more than a gift of ten thousand crowns."[180] [179] Was kann mir ein Mensch thun? (Keith, L. Umstände, p. 89.) [180] Tenze, Hist. Ber. ii, p. 168.
