Philipp Melanchthon, along with Martin Luther and…

Philipp Melanchthon, along with Martin Luther and probably Justus Jonas, writes the so-called Articles of Schwabach (so named because they are presented at the Convention of Schwabach on October 16 of the same year) beginning in July 1529, as a confession of faith with other Wittenberg theologians.

Material from this document will later be incorporated into the Augsburg Confession written by Melanchthon in 1530.

During Luther's stay in the Wartburg, Jonas had been one of the most active of the Wittenberg reformers.

Giving himself up to preaching and polemics, he has aided the Reformation by his gift as a translator, turning Luther's and Melanchthon's works into German or Latin as the case might be, thus becoming a sort of double of both.

Jonas has also assisted Luther with his translation of the Bible into German.

One of the eight hymns in the first Lutheran hymnal is attributed to him, In Jesu Namen wir heben an (In the name of Jesus we begin), which appeared in 1524 with four hymns by Martin Luther and three by Paul Speratus.

His hymn "Wo Gott der Herr nicht bei uns hält", a paraphrase of Psalm 124, was published in the Erfurt Enchiridion in 1524.

It was used by several composers as a base for organ and choral music, including Bach's chorale cantata BWV 178.
