He answered in a friendly letter to Luther on February 13, 1526, that he had been pleased to take note of the difficulty, and would for the future know how to comport himself in these matters in a Christian and irreproachable manner.[986] Subsequent to this assurance he acted as an apt pupil of the Wittenberg Professor. In accordance with the instructions given by the Elector in 1527 for the general Visitation of the Churches in the Saxon Electorate, an “inquisition” was to be held everywhere by the ecclesiastical Visitors as to whether any “sect or schism” existed in the country. Whoever was “suspected of error in respect of the sacraments or some doctrine of faith” was to be “summoned and interrogated, and, if the occasion required, hostile witnesses were to be heard”; if any refused to give up their “error,” they were commanded to sell their possessions within a given time and to quit the country.[987] One thing only was still wanting, viz. that the people should be compelled by the Ruler to attend the Lutheran sermons and services. Even this was, however, implied in the regulations, since those who did not attend were classed among the “suspects.” As time went on Luther demanded the exercise of such coercion, and it was actually introduced in the Electorate and, later, in the Protestant Duchy of Saxony.[988] The proceedings on the introduction of the innovations in other districts were similar to those in the Electorate of Saxony. Wherever a small group of persons were willing to throw in their lot with the first local representatives of the new faith--generally clerics--they were backed up by the State authorities, who reconstructed the religious system as they thought best. “Nowhere was the primitive Lutheran ideal realised of a congregation forming itself in entire independence.... Thus at an early date Lutheranism took its place among the political factors, and its development was to a certain extent dependent upon the tendencies and inclinations of the authorities and ruling sovereigns of that day.”[989] The Electors Frederick and Johann of Saxony were gradually joined by a number of other Princes who introduced the innovations into their lands, and the magistrates of the larger, and even of some of the smaller, Imperial cities soon followed suit. Thus the whole movement, having owed its success so largely to the authorities, was governed and exploited by them and assumed a strongly political character, needless to say, much to the detriment of its religious aspect.
