St Luke Passion, BWV 246

A surviving manuscript of the St Luke Passion from about 1730 is partly in Bach's hand, though scholars believe that the music is certainly not his own. The music was later thought to have been composed by Johann Melchior Molter, but that was proven false because if Molter composed the music, then the manuscript would date to later than 1730.[2] Presumably Bach performed it, or intended to perform it, in Leipzig. C. P. E. Bach and Agricola may have mistaken it for a work of Bach's and thus included it in their census. Of course, given his delight in exhaustive cycles, Bach should have composed a St Luke Passion. Apparently J. S. Bach took the anonymous St Luke Passion and arranged it for four voices, chorus, orchestra, and continuo to meet an urgent deadline for Good Friday in 1730.

With regard to the authorship of the passion, Felix Mendelssohn commented in a letter to Franz Hauser who had just paid a large sum of money to purchase the Lukaspassion: "I am sorry to hear you have given so much money for the St. Luke Passion." Mendelssohn repudiated Bach's authorship of the work upon the evidence of a single chorale, 'Weide mich und mach' mich satt' (No. 9). He continued:

"No doubt, as an authentic autograph, it would be worth the price. But it is not by Bach. You ask, 'On what grounds do you maintain your opinion?' I answer, on intrinsic evidence, though it is unpleasant to say so, since it is your property. But just look at the chorale, 'Weide mich und mach' mich satt'! If that is by Sebastian, may I be hanged! It certainly is in his handwriting, but it is too clean. Evidently he copied it. 'Whose is it?' you ask; 'Telemann, or M. Bach, or Altnichol?' Jung Nichol or plain Nichol, how can I tell? It's not by Bach. Probably it is of North German origin." (Terry, 78).

A performance of the St. Luke Passion, specifically the aria "Lasst mich ihn nur noch einmal küssen" was used by musician Leyland James Kirby, also known as The Caretaker, in a track called "Friends Past Reunited." He used the track in multiple albums, most notably his first album, Selected Memories From The Haunted Ballroom(1999) and A Stairway To The Stars(2001). He also used the same performance recording as the ending to Stage 6 of his final project, Everywhere at the End of Time(2016-2019).[3][4] The exact performance remains unknown.
