The Autograph Score:
This score was probably inherited by W.F. Bach and in October of 1761, because of the property that his wife owned, he was forced to make a larger than expected contribution to the war effort (7-Years War), so he decided to sell the cantatas from the early part of this yearly (1725) cantata cycle, which were not complete in any case. The next owner that can be documented is Johann Georg Nacke (1718-1804), a cantor in the town of Oelsnitz. His initials and year (J.G.N. | 1762) appear on the score. After his death, this cantata and other Bachiana came into the possession of his successor as cantor: Johann Gottlob Schuster (1765-1839), who then sold it to Franz Hauser in 1833. In 1904 the BB purchased the Hauser collection which contained this score. During WWII the score was taken to the Silesian monastery in Grüssau and after the war (1946) in ended up in the Biblioteka Jagiellońska in Kraków where it is located today.
On the title page Bach wrote the following:
J.J. Doica (there is a fermata over the ‘i’ and ‘c’) 3. post Epiphan. Was mein Gott will, das g’scheh allzeit.
The Original Set of Parts:
It is very likely that this set went to Anna Magdalena who gave them to the St. Thomas School, but every trace of them has been lost. Three doublets which were separated from this set, went along with the autograph score and are now located in the BB.
The Text and 1st Performance:
Despite the theories that abound that Bach and a pastor who delivered the sermon on January 21, 1725 in Leipzig collaborated on writing the text, the NBA KB I/6 (1996) still believes that the librettist is unknown. This unknown librettist based the text on the chorale, “Was mein Gott will, das g’scheh allzeit” by Duke Albrecht of Prussia (1547) with the inclusion of 4th verse by an anonymous individual (Nürnberg, 1554). Verses 1 and 4 are used verbatim in mvts. 1 & 6. Mvts. 2 to 5 base their material upon the 2nd and 3rd verse of the chorale.
