Christ unser Herr zum Jordan kam in E minor, BWV 7 "Christ our Lord came to the Jordan"

It is the third cantata Bach composed for his chorale cantata cycle, the second cycle he started after being appointed Thomaskantor in 1723. The cantata is based on the seven stanzas of Martin Luther's hymn "Christ unser Herr zum Jordan kam", about baptism. The first and last stanza of the chorale were used for the outer movements of the cantata, while an unknown librettist paraphrased the inner stanzas of the hymn into the text for the five other movements. The first movement, a chorale fantasia, is followed by a succession of arias alternating with recitatives, leading to a four-part closing chorale.
