 Unlike Bach's earlier existing passions ("St John Passion" and "St Matthew Passion"), the "Markus-Passion" is probably a parody—it recycles previous works.The "St Mark Passion" seems to reuse virtually the whole of the Trauer Ode "Laß, Fürstin, laß noch einen Strahl", BWV 198, along with the two arias from "Widerstehe doch der Sünde", BWV 54.In addition, two choruses from the "St Mark Passion" were reused in the Christmas Oratorio.
