On high feast days during Bach’s time, settings of Latin prayers and other texts could be heard at Sunday service in Leipzig: Kyrie, Gloria, Sanctus in the morning and the Magnificat in the afternoon. Although many of these were existing repertoire pieces, Bach also made his own settings from his earliest days as Thomascantor, such as the Sanctus in D (BWV 238), presumably composed for Christmas Day in 1723. This setting by Daniel Pinkham contains violin 1 part only.
