The city of Braunsberg was then part of the Diocese of Warmia (Ermland), a prince-bishopric under rule of Cardinal Hosius.

Loci Communes Loci Communes or Loci communes rerum theologicarum seu hypotyposes theologicae (Latin for "Common Places in Theology or Fundamental Doctrinal Themes") was a work by the Lutheran theologian Philipp Melanchthon published in 1521 (other, modified editions produced in the life of the author occurred in: 1535, 1543 and 1559). Martin Luther said of it that "Next to Holy Scripture, there is no better book," and its existence is a common reason given for why Luther never wrote a systematic theology of his own. In an overture to the English king, Henry VIII, to gain the English crown as converts to Lutheran protestantism, Philipp Melanchthon provided a dedication to the king in one of his printed editions.
