Sammartini had a long and active musical career, working as maestro di cappella or organist in as many as ten different churches, yet surprisingly few of his sacred compositions survive. In the sacred cantata Gerusalemme sconoscente ingrata, set to a text from another of his cantatas, La perfidia giudaica nella SS. Passione di Gesù Cristo, vocal texture is dominated by a typically Italianate melodiousness and virtuosity, while the orchestral writing is full of daring harmonies, sparkling themes, and an inexhaustible wealth of ideas.

The cantata Della Passione di Gesù Cristo, J-C 124 (On Jesus Christ's Passion), was first performed in San Fedele on 9 March 1759, the first Friday of Lent. This title, which was published in the catalogue of Sammartini's works (Harvard University Press, 1976), does not correspond to the text found in Father Keller's manuscript. The text belongs instead to the cantata Gerusalemme sconoscente, ingrata (Jerusalem, ungrateful and disowning), which bears the number J-C 122. In the catalogue, this number belongs to the text of the cantata La perfidia giudaica (The Jewish Wickedness), which is considered lost and is catalogued as number C-49. According to the current state of research the 1760 cantata Della Passione di Gesù Cristo, Signor nostro seems to be lost.

Sacred Cantatas Naxos' Eighteenth Century Classics series treats listeners to a couple of samplings from a genre in which Giovanni Battista Sammartini, "father of the symphony," was involved to a largely unknown extent, the sacred cantata. Both of these works come from 1751, which must have been a very sad year indeed for this composer, as they are Maria Addolorata (The Sorrowing Mary) and Il pianto di San Pietro (The Tears of Saint Peter). These works have been edited for publication by musicologist Daniele Ferrari, and are recorded here with Ferrari himself conducting.
