The Emperor, on March 6th, issued a citation to Luther, summoning him to Worms to give "information concerning his doctrines and books." An imperial herald was sent to conduct him. In the event of his disobeying the citation, or refusing to retract, the estates declared their consent to treat him as an open heretic. Luther, therefore, had to renounce at once all hope of having the truth touching his articles of faith tested fairly at Worms by the standard of God's word in Scripture. Spalatin indicated to him the points on which he would in any case be expected to make a public recantation. Luther formed his resolve at once on the two points required of him. He determined to obey the summons to the diet, and, if there unconvicted of error, to refuse the recantation demanded. The Emperor's citation was delivered to him on March 26th by the imperial herald, Kaspar Sturm, who was to accompany him to Worms. Within twenty-one days after its receipt, Luther was to appear before the Emperor; he was due therefore at Worms on April 16th at the latest. On April 2d, the Tuesday after Easter, he set out on his way to Worms. His friend Amsdorf and the Pomeranian nobleman Peter Swaven, who was then studying at Wittenberg, accompanied him. He took with him also, according to the rules of the order, a brother of the order, John Pezensteiner. The Wittenberg magistracy provided carriages and horses. The way led past Leipzig, through Thuringia from Naumburg to Eisenach, southward past Berka, Hersfeld, Gruenberg, Friedberg, Frankfort, and Oppenheim. The herald rode on before in his coat-of-arms, and announced the man whose word had everywhere so mightily stirred the minds of people, and for whose future behavior and fate friend and foe were alike anxious. Everywhere people collected to catch a glimpse of him. On April 6th he was very solemnly received at Erfurt. The large majority of the university there were by this time full of enthusiasm for his cause. Meanwhile at Worms disquietude and suspense prevailed on both sides. Hutten[29] from the castle of Ebernburg sent threatening and angry letters to the papal legates, who became really anxious lest a blow might be struck from that quarter. Some anxious friends of Luther's were afraid that, according to papal law, the safe-conduct would not be observed in the case of a condemned heretic. Spalatin himself sent from Worms a second warning to Luther after he had left Frankfort, intimating that he would suffer the fate of Huss. But Luther continued on his way. To Spalatin he replied, though Huss were burned, yet the truth was not burned; he would go to Worms though there were as many devils there as there were tiles on the roofs of the houses.
