Younger depicting biographical events of Davids life in relation to the New Testament. The book saw four further editions in the latin language within half a year. A second edition by Adam Petri in August, one by Johannes Petreius in Nuremberg and also by Johannes Knobloch in Strassburg. Another one is assumed to have been printed by Johann Schöffer in Mainz. Two years later, a German translation was printed by Adam Petri in which for the Psalms text, the German translation by Martin Luther were used. Bugenhagen was regarded as one of the most important teachers and practitioners of biblical interpretation in the Wittenberg-centered Protestant Reformation, ordaining a generation of Lutheran pastors who were educated at this university. On 17 March 1533, he was promoted doctor of theology at the university of Wittenberg, together with Johannes Aepinus and Kaspar Cruciger. The promotion was supervised by Martin Luther, based on Philipp Melanchthon's theses, financed and attended by Frederick III, Elector of Saxony, and formally granted by deacon Justus Jonas. With the ceremony in Wittenberg's castle church (Schloßkirche), Aepinus, Bugenhagen and Cruciger became the first three Protestant doctors of theology. While theological doctoral promotions had been suspended in Wittenberg for the preceding eight years, the promotion of Aepinus had become necessary as the Hamburg burghers demanded their new superintendent to bear the title of a doctor.

Bugenhagen produced rules and regulations for religious service, for schooling, and for social issues of the church. In 1539, he became superintendent of the Lutheran Church in Saxony. Also in 1539, Bugenhagen reformed the Pomeranian University of Greifswald, which he "re-founded"
