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.
[1][2] The Mass is composed for soprano, alto, tenor and bass soloist singers, and a choir consisting of the four same voice types (SATB).
The oboes are silent throughout Zelenka's Credo, and the BWV 239 Sanctus only requires a four-part choir, strings and continuo.
In the 2010s the Bach Digital website described BWV 239 as a work derived from the first section of the Gloria of Caldara's Missa Providentiae.
