At Rome the trouble in Germany was one of the main subjects that engaged the attention of the Curia. It was felt that the time had come when decisive measures must be taken. After long and anxious deliberations Leo X. published the Bull, /Exsurge Domine/ (June 1520), in which forty propositions taken from Luther's writings were condemned, his works were ordered to be burned, the full penalties of excommunication were proclaimed against him unless he withdrew his errors and made his submission within sixty days, while his aiders and abettors were besought in the most touching terms to abandon the dangerous path into which they had been betrayed. Had such a pronouncement been issued at the beginning of the movement it might have done much to restore peace to the Church, but, coming as it did at a time when Luther's movement, backed by all the revolutionary forces of Germany, had already acquired considerable dimensions, it failed to put an end to the tumult. Besides, the papal decision was deprived of much of its force by the fact that Eck, Caraccioli, and Aleandro were appointed as a commission to superintend its execution. The appointment of Eck was a great tactical blunder, as it afforded Luther and his friends an opportunity of proclaiming that the sentence of excommunication was procured by the intrigues and misrepresentations of their personal enemies; while the fact that the German bishops were disregarded in the execution of the Bull as if they were not above suspicion themselves, was looked upon by many as a studied insult to the entire German hierarchy. Even though Luther had entertained any thoughts of submission, the triumph of Eck would have created very serious obstacles; but, knowing as he did, that even at the worst he could reckon upon the support of a certain number of the discontented nobles who had pledged themselves to put their swords at his disposal, he had no intention of making his submission.
