"He brought the written word to the masses!" -- during a time when the majority couldn't read.
"He freed the written word from Latin!" -- during a time when anything of consequence was recorded in Latin -- furthermore, proper translations that had been not been butchered by reformers were available in vernacular languages long before Luther came on the scene...Which were about as useful as Latin bibles to the majority of the population whom, again, were illiterate.
"Luther removed heretical editions the Catholics made to the Church!" -- such as Marian devotion, the rosary, sacred music and incense and vestments, liturgy...Oh, wait a minute, no he didn't. Misguided and wrong as Luther was, much of the changes attributed to him are the work of later Protestants.
"He freed the population from the corrupt Church hierarchy!" -- There was a lot of corruption among the hierarchy, and guess what? Much of it kept on rolling both during and after the reformation. lord-Bishops, burghers, princes, landgraves, who had been corrupt Catholics, became corrupt Protestants. Contrary to the neat (not to mention laughable) Protestant image of Post tenebras lux, the reformation was messy, inexact, and fitful. Regional politics heavily influenced how people and places embraced or opposed the reformation. princes and bishops, especially in Germany, could be Lutheran, Catholic, Lutheran-leaning Catholics or Catholic-leaning Lutherans, Lutherans who sided with Catholics or vice-versa for reasons of their own, etc. A bishop might very well continue to hold his position, allow some changes but not others, and nobody could be sure where exactly his loyalties lay. The sack of Munster (if you visit you can still see the metal cages in which Protestants roasted other Protestants alive) and the events leading up to it provide an excellent example of the type of confusion that permeated the era.
If you read carefully, I simply expressed great thankfulness that blessed Luther recovered the Gospel of Grace that saves.
Nothing personal against Germans, but considering all this and the heretical Bishops we have there now nothing good seems to come from the German church.
