Wolfgang Musculus (born MüslinorMauslein; 10 September 1497 – 30 August 1563) was a Reformed theologian of the Reformation.
Born in the village of Duss (Moselle), in a German-speaking area (French-speaking, from the Thirty Years War), Musculus was a lover of song and of knowledge, of languages, Humanism and religion. The oral tradition of his songs is still found in the churches of the Reformation.
In 1527, he left the Benedictine monasteryatLixheim (now in the area of Moselle), to serve as deacon of the Cathedral of Our Lady of Strasbourg (French: Cathédrale Notre-Dame-de-Strasbourg) and preaching assistant to Matthäus Zell while studying under Bucer and Capito. He left for Augsburg in 1531, and after 17 years of service, he left the town after the introduction of the Augsburg Interim, and came to Switzerland, where he was the primary professor of theology at Bern from 1549. At Bern, he wrote several biblical commentaries and Loci communes sacrae theologiae (Common Places of the Christian Religion), a major systematic theology.[1]
J. S. Bach used Musculus' 1530 hymn, a paraphrase of Psalm 23, as the text for his chorale cantata Der Herr ist mein getreuer Hirt, BWV 112, which he first performed in Leipzig in 1731.[2][3]
