Above the doors is a painting that portrays Luther on the left with a German Bible, and Philipp Melanchthon on the right, with the Augsburg Confession, the main confession of faith in the Lutheran Church which was formed by Luther and Melanchthon.
Through the influence of Camerarius and Melanchthon, he obtained a post at Nuremberg (1526), but, finding a regular life distasteful, he again went back to Erfurt (1533).
Curiously enough Melanchthon's letter introducing Sozzini to Maximilian II invokes as an historic parallel the hospitable reception rendered by the Emperor Constantine to Athanasius when he fled from Egypt to Trèves.
Melanchthon's treatment is not only more clear than that of his predecessor, but he draws his examples from the Bible instead of from the Church Fathers, and under Pauline influence deduces, in addition to loci communes, certain loci communissimi, such as "sin," "grace," and "law."
With his title of "royal typographer" Estienne made the Paris establishment famous by his numerous editions of grammatical works and other school-books (among them many of Melanchthon's), and of classical and Patristic authors, as Dio Cassius, Cicero, Sallust, Julius Caesar, Justin, Socrates Scholasticus, and Sozomen.
The Two Kinds of Righteousness is explicitly mentioned in Luther’s 1518 sermon entitled Two Kinds of Righteousness, in Luther’s Galatians Commentary (1535), in his Bondage of the Will, Melanchthon’s Apology of the Augsburg Confession, and in the third article of the Formula of Concord.
