After studying in Ingolstadt, Osiander initially worked as a pastor in Nuremberg at St. Lorenz from 1522 , at the appointment of the local provost Hektor Poemer (1495–1541). [ 1 ] Convinced by the theology of Martin Luther, he implemented the Reformation in Nuremberg together with his companions, the painter Albrecht Dürer , the humanist and councilor Willibald Pirckheimer as well as the council clerk Lazarus Spengler and the master singer Hans Sachs . Osiander was the main author of the important church order of 1533, which was influential far beyond Nuremberg and was introduced simultaneously in Nuremberg and in the neighboring Margraviate of Brandenburg-Ansbach . [ 2 ]

Osiander also played a key role in the renewal of the church in the Upper Palatinate . He provided the template for the edict of the sovereign Otto Heinrich and developed a new church order . Osiander was also behind the dismissal of the Protestant-minded headmaster of the Sebaldus School, Hans Denck , who later joined the Anabaptists of the Reformation .

In 1549, Osiander was appointed professor of theology by Duke Albrecht of Brandenburg-Ansbach at the still young Albertus University in Königsberg , founded in 1544. There he became involved in a heated argument with the followers of Philipp Melanchthon , Luther's close companion. The dispute was about the doctrine of justification , one of the core statements of Reformation theology. For Melanchthon, a sinner remained a sinner to the core even after being justified before Christ. Osiander, on the other hand - similar to the position of the Eastern churches - was of the opinion that the righteousness of Christ is implanted in man through faith and thus becomes an essential part of the believer.

This so-called Osiandrian controversy agitated and divided Protestantism for many years. Ultimately, Osiander and his followers went their own ways on this theological question, which was important for the Reformation, throughout their lives. [ 3 ]

Osiander was considered an expert in the Hebrew language and Jewish mysticism . Unlike Luther, he sought a genuine dialogue with the Jews , fought vigorously for their rights and rejected every form of anti-Judaism . In 1540, his work "Whether it is true and credible that the Jews secretly strangle Christian children and use their blood" was published (anonymously), in which he refuted the accusation of ritual murder and other accusations against the Jews. [ 4 ]

It was also Osiander who added a foreword to Nicolaus Copernicus ' work De revolutionibus orbium coelestium before its publication in Nuremberg in 1543, which presented Copernicus' theory as a mere calculation model with no claim to correspond to reality. He failed to make it clear that these sentences came from his pen and not from Copernicus's. For a long time, the opinion prevailed that Copernicus did not really believe in his model. He also made a number of other changes to the work that were not authorized by Copernicus: he deleted important passages and added sentences.
