After this, on April 26, in accordance with the command of the Emperor, he was obliged to quit Worms. An extension of the safe conduct for twenty-one days was expressly granted him, coupled, however, with the injunction not to preach or publish anything on the way. Two days later, while on his journey, Luther forwarded a missive to the Emperor and another to the Estates in his own defence, the latter being immediately printed by his friends as a broadsheet. The print depicted Luther with a halo, and the dove or symbol of the Holy Ghost hovering over him.
The fact that at the time the Diet was sitting a committee of the Estates brought forward, under a new form, the so-called “Gravamina of the German Nation” against the Roman See, was greatly to the advantage of Luther’s cause. They consisted largely of legitimate suggestions for the amelioration of ecclesiastical conditions and the removal of the oppression exercised by the Curia. These were made the subject of debate, and were exploited in Luther’s interests by those desirous of innovations. Those among the Humanists who sided with him, and likewise the Knights of the Empire, had taken various steps during his stay at Worms to strengthen his position and to frighten the Estates by hinting at violent action to be undertaken on his behalf.
Ulrich von Hutten wrote to him from the Ebernburg on April 17: “Keep a good heart ... I will stand by you to the last breath if you remain true to yourself.” He knows how those assembled at the Diet gnash their teeth at him; his fancy indeed paints things black, but his hope in God sustains him.[156] In a second letter of April 20, Hutten speaks to him of trusting not only in God and His Christ, but also in earthly weapons: “I see that sword and bow, arrows and bolts are necessary in order to withstand the mad rage of the devil ... the wisdom of my friends hinders me from a venture, because they fear lest I go too far, otherwise I should already have prepared some kind of surprise for these gentlemen under the walls [of Worms]. In a short time, however, my hand will be free, and then you shall see that I will not be wanting in the spirit which God has roused up in me.”[157] In the same way as in his rhetorical language he ascribes his own mood to the illumination of the Spirit of God, so Hutten also sought to unearth a Divine inspiration in his friend Franz von Sickingen; all this was the outcome of Luther’s pseudo-mysticism, to which his friends were indebted for such figures of speech. Regarding Sickingen, Hutten wrote to Willibald Pirkheimer: “He has, so to speak, drunk in Luther completely; he has his little books read aloud at table, and I have heard him swear that he will never forsake the cause of truth in spite of every danger.” “You may well regard these words as a Divine Voice, so great is his constancy.”[158]
