Martin Luther transformed from an Austin friar and pastor to a critical theologian and eventually to a reformer. His theological approaches had extensive consequences for theology and clerical life. During the political power constellations of the 16th century, principalities used his demands to repress the power of the Pope and the Emperor. Luther’s rhetoric and authorial gift, just like his charismatic personality, had great effects on his contemporaries. To this day, the Lutheran bible is ranked among the most important bible translations and is still used by Protestants. Luther’s published works include numerous texts and letters, as well as a huge amount of sermons and dinner speeches – but he is also known as an infamous poet of church songs through his contribution to church music.
