About this time (1539), in Brandenburg, the Elector Joachim II. also ushered in the innovations. The rights and possessions of the ancient Church fell a prey to the spoilers. Luther praised the ruler for going forward so bravely “to the welfare and salvation of many souls.” He was, however, apprehensive lest the “roaring of the lion in high places” might influence the Elector; with the Divine assistance, however, he would not fear even this.[629] He showed himself strangely lenient in regard to the Elector’s prudent retention of much more of the Catholic ceremonial than had been preserved in any other German land. Even the Elevation of the Sacrament at Mass (or rather at the sham Mass still in use) was tolerated by Luther; he writes: “We had good reasons for doing away with the elevation [of the Sacrament] here at Wittenberg, but perhaps at Berlin you have not.”[630] In the Duchy of Prussia, formerly ecclesiastical property of the Teutonic Knights, the way had been paved for the apostasy of these Knights, all bound by the vow of chastity, by Luther’s alluring tract “An die Herrn Deutschs Ordens, das sic falsche Keuscheyt meyden und zur rechten ehlichen Keuscheyt greyffen.”[631] Albert, the Grand Master, who had visited Luther twice, as already narrated, seized upon the lands of the Order belonging to the Church and caused himself to be solemnly invested and proclaimed hereditary Duke of Prussia on April 10, 1525; thereupon Luther sent him his congratulations that God should have so graciously called him to this new Estate. The Grand Master, himself a married man, with the assistance of the two apostate Bishops of Samland and Pomerania, then established Lutheranism. As chief Bishop he assumed the position of head of the territorial Church, agreeably with the Protestant practice in the other German lands. The episcopal jurisdiction was transferred to the civil Consistorial Courts. Violent appropriation of alien property, as well as illegal assumption of ecclesiastical jurisdiction, also characterised the advent of the new faith in Würtemberg. Duke Ulrich, who had been raised to the throne in 1534 by a breach of the peace of the Empire and contrary to all law and justice, thanks to the successful raid of Philip of Hesse (above, p. 47; vol. iii., p. 67 f.), continued to labour under the stigma attaching to the manner in which he had obtained the Duchy, in spite of the peace he had patched up with the Emperor. The religious transformation of the country was however, soon accomplished, thanks to his pressure. The chief part in this, so far as Upper Würtemberg was concerned, devolved on the preacher, Ambrosius Blaurer (Blarer), who favoured the Zwinglian leanings of Bucer.
