On the way he found a new imperial edict posted up, which ordered all his books to be seized, as having been condemned by the Pope and being contrary to the Christian faith. Charles V. by this edict had given satisfaction again to the legates, who were annoyed at Luther being summoned to Worms. Many doubted whether Luther, after this condemnation of his cause by the Emperor, would venture to present himself in person at Worms. He himself was alarmed, but travelled on. Meanwhile at Worms disquietude and suspense prevailed on both sides. Hutten 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. Aleander complained that Sickingen now was king in Germany, since he could command a following whenever and as large as he pleased. But in truth he was in no case ready for an attack at that moment. He still reckoned on being able, with his Church sympathies, to remain the Emperor's friend, and was just now on the point of taking a post of military command in his service. 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. Meanwhile Glapio, on the other side, no doubt with the knowledge and consent of his imperial master, made one more attempt in a very unexpected manner to influence Luther, or at least to prevent him from going to Worms. He went with the imperial chamberlain, Paul von Armsdorf, to Sickingen and Hutten at the Castle of Ebernburg, spoke of Luther as he had formerly done to Brück, in an unconstrained and friendly manner, and offered to hold a peaceable interview with Luther in Sickingen's presence. Armsdorf at the same time earnestly dissuaded Hutten from his attacks and threats against the legates, and made him the offer of an imperial pension if he would desist. Had Luther agreed to this proposal and gone to the Ebernburg, he could not have reached Worms in time; the safe-conduct promised him would have been no longer valid, and the Emperor would have been free to act against him. Nevertheless Sickingen entered into the proposal. The danger threatening Luther at Worms must have appeared still greater to him, and Luther could then have enjoyed the protection of his castle, which he had offered him before. Martin Butzer, the theologian from Schlettstadt, happened then to be with Sickingen; he had already met Luther at Heidelberg in 1518, had then learned to know him, and had embraced his opinions. He was now commissioned to convey this invitation to him at Oppenheim, which lay on Luther's road.
