Georg Philipp Telemann, in his capacity as church music director in
Hamburg, organised a festival in the city in 1730 to celebrate the bicentenary of the
Augsburg Confession. He contributed two cantatas, which were performed at the Katharinenkirche on 25 June, before and after the service. In the same year, he composed the motet
Ein feste Burg ist unser Gott as a choral setting of Luther's
hymn "Ein feste Burg ist unser Gott", known in English as "
A Mighty Fortress Is Our God", for a
four-part choir and continuo. The motet was first published around 1780 in a collection of 34 motets. A modern edition was published by
Carus-Verlag in 1978 and again in 1992, edited by
Günter Graulich. == Text and music ==
