THE opening of the Diet of Ratisbon in 1541[595] coincided with the advance of Protestantism in one of the strongholds of the power and influence of Albert of Mayence. The usual residence of the Archbishop and Elector was at Halle, in his diocese of Magdeburg. Against this town accordingly all the already numerous Protestants in Albert’s sees of Magdeburg and Halberstadt directed their united efforts. Albert was compelled by the local Landtag to abolish the Catholic so-called “Neue Stift” at Halle, and to remove his residence to Mayence. Thereupon Jonas, Luther’s friend, at once, on Good Friday, 1541, commenced to preach at the church of St. Mary’s at Halle. He then became permanent preacher and head of the growing movement in the town, while two other churches were also seized by Lutheran preachers. The town and bishopric of Naumburg, which had been much neglected by its bishop, Prince Philip of Bavaria, who resided at Freising, fell a prey to the innovations under the Elector Johann Frederick of Saxony; this in spite of being an imperial city under the immediate protection of the Emperor. The Elector had taken advantage of his position as arbitrator, thanks to his influence and to the authority he soon secured, gradually to establish himself in Naumburg. By his orders, in 1541, as soon as Philip was dead, Nicholas Medler began to preach at the Cathedral as “Superintendent of Naumburg”; Julius Pflug, the excellent Provost, who had been elected bishop by the Cathedral chapter, was prevented by the Elector from taking possession of the see. Even the Wittenberg theologians were rather surprised at the haste and violence with which the Elector proceeded to upset the religious conditions there, and—a matter which concerned him deeply—to seize the city and the whole diocese. (See below, p. 191 f.) The storm was already gathering over the archbishopric of Cologne under the weak and illiterate Archbishop, Hermann von Wied. This man, who was in reality more of a secular ruler, after having in earlier days shown himself kindly disposed to the Church, was won over, first by Peter Medmann in 1539 and then by Martin Bucer in 1541, and persuaded to introduce Lutheranism. Only by the energetic resistance of the chapter, and particularly of the chief Catholics of the archdiocese, was the danger warded off; to them the Archbishop owed, first his removal, and then his excommunication. On March 28, 1546, shortly before the excommunication, the Emperor Charles V said to Landgrave Philip of Hesse, who had been pleading the cause of Hermann: “Why does he start novelties? He knows no Latin, and, in his whole life, has only said three Masses, two of which I attended myself. He does not even understand the Confiteor. To reform does not mean to bring in another belief or another religion.”[596]
