The king was energetically seconded by the Parlement of Paris. A royal edict provided that no book should be printed without the imprimatur of the university. The king next ordered the extirpation of the errors of Martin Luther of Saxony, and, having begun by burning books, continued, as Erasmus observed was usually the case, by burning people. The first to suffer was John Valliere. At the same time Briconnet was summoned to Paris, [Sidenote: 1523] sharply reprimanded for leniency to heretics and fined two hundred livres, in {192} consequence of which he issued two decrees against the heresy, charging it with attempting to subvert the hierarchy and to abolish sacerdotal celibacy. [Sidenote: 1524] When Lefevre's doctrines were condemned, he submitted; those of his disciples who failed to do so were proscribed. But the efforts of the government became more strenuous after 1524. Francis was at this time courting the assistance of the pope against the emperor, and moreover he was horrified by the outbreak of the Peasants' War in Germany. Convinced of the danger of allowing the new sect to propagate itself any further he commanded the archbishops and bishops of his realm to "proceed against those who hold, publish and follow the heresies, errors and doctrines of Martin Luther." [Sidenote: 1525] Lefevre and some of his friends fled to Strassburg. Arrests and executions against those who were sometimes called "heretics of Meaux," and sometimes Lutherans, followed. The theologians did not leave the whole burden of the battle to the government. A swarm of anti-Lutheran tracts issued from the press. Not only the heresiarch, but Erasmus and Lefevre were attacked. Their translations of the Bible were condemned as blasphemies against Jerome and against the Holy Ghost and as subverting the foundations of the Christian religion. Luther's sacramental dogmas and his repudiation of monastic vows were refuted.
