The Mass in B minor, BWV 232, is an extended setting of the Mass ordinary by Johann Sebastian Bach. The composition was completed in 1749, the year before the composer's death, and was to a large extent based on earlier work, such as a Sanctus Bach had composed in 1724. Sections that were specifically composed to complete the Mass in the late 1740s include the "Et incarnatus est" part of the Credo.
