Missa Providentiae is a Kyrie–Gloria Mass in D minor composed by Antonio Caldara, which around 1728 was expanded into a Missa tota by Jan Dismas Zelenka: this composer derived a Sanctus and Agnus Dei from Caldara's Kyrie and Gloria, and added a Credo, ZWV 31, of his own hand. Around 1738–1741, Johann Sebastian Bach made a copy of a Sanctus, BWV 239, which was based on the first section of the Gloria of Caldara's Kyrie–Gloria Mass.
