"Now thank we all our God" is a popular Christian hymn. Catherine Winkworth translated it from the German "", written by the Lutheran pastor Martin Rinkart. Its hymn tune, Zahn No. 5142, was published by Johann Crüger in the 1647 edition of his Praxis pietatis melica. Background Martin Rinkart was a Lutheran pastor who came to Eilenburg, Saxony, at the beginning of the Thirty Years' War. The walled city of Eilenburg became the refuge for political and military fugitives, but the result was overcrowding, deadly pestilence and famine. Armies overran it three times. The Rinkart home was a refuge for the victims, even though he was often hard-pressed to provide for his own family. During the height of a severe plague in 1637, Rinkart was the only surviving pastor in Eilenburg, conducting as many as 50 funerals in a day. He performed more than 4,000 funerals in that year, including that of his wife. Rinkart was a prolific hymn writer. In Rinkart's (Leipzig, 1636), "" appears under the title "", as a short prayer before meals. The exact date is debated, but it is known that it was widely sung by the time the Peace of Westphalia was signed in 1648. Johann Crüger published it in the 1647 edition of his Praxis pietatis melica. Text Below is the text in a modern version from the German hymnal Evangelisches Gesangbuch, and a 19th-century translation by Catherine Winkworth: Melody The melody is sometimes attributed to Rinkart, but it is usually considered to be by Johann Crüger, who first published it. Musical settings It is used in J.S. Bach's cantatas, such as BWV 79, 192 (music lost), harmonized for four voices in BWV 252 and 386, and set in a chorale prelude, BWV 657, as part of the Great Eighteen Chorale Preludes. The now-standard harmonisation was devised by Felix Mendelssohn in 1840 when he adopted the hymn, sung in the now-standard key of F major and with its original German lyrics, as the chorale to his Lobgesang or Hymn of Praise (also known as his Symphony No. 2). Max Reger composed a chorale prelude as No. 27 of his 52 Chorale Preludes, Op. 67 in 1902. The late-Romantic German composer Sigfrid Karg-Elert used it in his Marche Triomphale. In 1969 Mr. Jo Mama also used Martin Rinkart's hymn to write a song entitled We Must Rejoice. ("For 2 tubas, 2 violas, and Organ
