Georg Philipp Telemann composed the motet Ein feste Burg ist unser Gott, TWV 8:7, setting Luther's hymn in German, "Ein feste Burg ist unser Gott", for a four-part choir and continuo.

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.

[1][2] 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.

[5][6] While Luther wrote the text in four stanzas as a paraphrase of Psalm 46, it became known as a Kampflied (battle song) of the Reformation.

Telemann structured the work in two sections, the first covering the first two stanzas of Luther's hymn as a chorale fantasia.
