No longer published in hymnals, this hymn is now most commonly recognized as one of the chorales incorporated into the St. John Passion, BWV 245, by J.S. Bach (1685-1750). Bach’s four-part harmonization of the hymn from the St. John Passion is played during the offering.
French organist and composer Marcel Dupré (1886-1971)’s enigmatic harmonization of the hymn is used as the prelude. Bach’s organ chorale prelude BWV 620 is our postlude today.
BWV or the Bach-Werke-Verzeichnis (Bach Works Catalog) is a numbering system for identifying the musical works of Johann Sebastian Bach. The compositions are grouped thematically, not chronologically. The system was published in 1950 by musicologist Wolfgang Schmieder (1901-1990) and has since become the standard for referencing the works of J.S. Bach around the world.
