An echo of his tempestuous sermon of November 27 is to be found in the pamphlet which Luther published at the commencement of 1525: “On the abomination of Silent Masses” (against the Canon of the Mass). In the Preface he refers directly to the inglorious proceedings against the unfortunate Chapter. He finds it necessary to declare that he, for his part, had aroused no revolt, for what was done by the established authorities could not be termed revolt; the “secular gentlemen,” who, according to him, constituted the established authorities, had, however, felt it their duty to take steps against the Catholic worship in the Collegiate Church. In that same year, 1525, under the auspices of the new Elector Johann, a great friend to Lutheranism, who succeeded the Elector Frederick upon his death on May 5, 1525, and whom Luther had long before won over to his cause, the order of Divine Service at Wittenberg was entirely altered. “The Pope” was at last, as Spalatin joyfully proclaimed throughout the city, “completely set aside.”[980] * * * * * Under the rule of the Elector Johann, Luther at once carried out the complete suppression of Catholic worship throughout the Electorate. On October 1, 1525, Spalatin wrote to the Elector Johann: “Dr. Martin also says, that your Electoral Grace is on no account to permit anyone to continue the anti-Christian ceremonies any longer, or to start them again.”[981] With the object of helping him in his work at Court and of removing any scruples he might have, Luther explained to Spalatin, in a letter of November 11 of the same year, that by stamping out the Catholic worship rulers would not be forcing the faith on anyone, but merely prohibiting such open abominations as the Mass; if anyone, in spite of all, desired to believe in it privately, or to blaspheme in secret, no coercion would be exercised.[982] No attention was paid to the rights of Catholics to a Divine Worship, attendance at which was to them a matter of conscience. They were simply to be permitted to emigrate; if they chose to remain they were not to “perform or take any part in any public worship.”[983] It was on such principles as these that the Memorandum which Spalatin presented to the Elector on January 10, 1526, was based.[984] Luther himself appealed to the Elector on February 9, 1526, seeking to “fortify his conscience” and to encourage him “to attack the idolaters with even greater readiness.” He points out to him, first, how damnable is the blasphemous, idolatrous worship; were he to afford it any protection, then “all the abominations against God would eventually weigh upon his, the Prince’s, conscience”; secondly, that differences in religious worship would inevitably give rise to “revolt and tumults”; hence the ruler must provide that “in each locality there be but one doctrine.”[985] To the force of such arguments Johann could not but yield.
