was Desiderus Erasmus, who declared that "The inclemency of the bull ill comports with the moderation of Leo" and also that "Papal bulls are weighty, but scholars attach much more weight to books with good arguments drawn from the testimony of divine Scripture, which does not coerce but instructs." For these reasons, its dissemination took several months to complete. Luther himself received an official copy bearing the papal seal in early October of that year. However, rumors of its existence reached Luther well in advance of the official copy. At first he doubted their veracity and thought that the document to which they referred may be a forgery, possibly by Eck himself. Nonetheless he commented that it was the work of the Antichrist, whatever its true origin may be, and started to compose a response even before he had received an official copy. His response was entitled Adversus Execrabile Antichristi Bullam (Against the Execrable Bull of the Antichrist). Luther defiantly proclaimed in his response that "whoever wrote this bull, he is Antichrist. I protest before God, our Lord Jesus, his sacred angels and the whole world that with my whole heart I dissent from the damnation of this bull, that I curse and execrate it as sacrilege and blasphemy of Christ, God's Son and our Lord. This be my recantation, O bull, thou daughter of bulls." He subsequently took issue with the censure of his statements: "My articles are called 'respectively some heretical, some erroneous, some scandalous', which is as much to say, 'We don't know which are which.' O meticulous ignorance! I want to be instructed, not respectively, but absolutely and certainly. ... Let them show where I am a heretic, or dry up their spittle." Much of the remainder of the tract is devoted to a discussion of the censured propositions. With the publication of the bull, sporadic public burnings of Luther's works began to take place in Germany in accordance with Leo X's instructions. However, in some places this directive proved impossible or difficult to carry out because of Luther's popular support. On certain occasions, his followers managed to substitute his condemned books with wastepaper or anti-Luther tracts, or rescue some of his works from the flames before they were consumed. On 29 November 1520, Luther published a second response to the bull entitled Assertion of All the Articles Wrongly Condemned in the Roman Bull. Luther's commentary
