Johann Christoph Bach (1642 –1703) was a German composer and organist of the Baroque period. He was born at Arnstadt, the son of Heinrich Bach, Johann Sebastian Bach's great uncle, hence he was Johann Sebastian's first cousin once removed. He was also the uncle of Maria Barbara Bach, J.S. Bach's first wife. Johann Christoph had a reputation as a composer that was only equalled by that of Johann Sebastian within the Bach family during his lifetime. He was organist at Eisenach and later a member of the court chamber orchestra there.
"Wir glauben all an einen Gott" and "Mit Fried und Freud ich fahr dahin" are part of the 44 Choral Preludes.
