On the Feast of St. John the Baptist, Bach led the first performance of Christ unser Herr zum Jordan kam, BWV 7, the third cantata of his chorale cantata cycle.

The Nativity of John the Baptist is a Christian feast day. It is observed annually on 24 June. The Nativity of John the Baptist is a high-ranking liturgical feast, kept in the Catholic Church, Eastern Orthodox Church, Anglicanism, and Lutheranism. The sole biblical account of the birth of John the Baptist comes from the Gospel of Luke.

Johann Sebastian Bach was a German composer and musician of the late Baroque period. He is known for his prolific output across a variety of instruments and forms, including the orchestral Brandenburg Concertos; solo instrumental works such as the cello suites and sonatas and partitas for solo violin; keyboard works such as the Goldberg Variations and The Well-Tempered Clavier; organ works such as the Schübler Chorales and the Toccata and Fugue in D minor; and choral works such as the St Matthew Passion and the Mass in B minor. Since the 19th-century Bach Revival, he has been widely regarded as one of the greatest composers in the history of Western music.

Christ unser Herr zum Jordan kam, BWV 7, is one of several church cantatas which Johann Sebastian Bach composed for the Feast of St. John the Baptist. He wrote it in Leipzig and led its first performance on 24 June 1724.

Johann Sebastian Bach's chorale cantata cycle is the year-cycle of church cantatas he started composing in Leipzig from the first Sunday after Trinity in 1724. It followed the cantata cycle he had composed from his appointment as Thomaskantor after Trinity in 1723.
