The Sanctus

I referenced "the Sanctus" in an earlier post and thought I should have a slight explanation:

The Sanctus is the part of the Mass in which the congregation or choir sings, chants, or recites the hymn that the angels sang in Isaiah 6:3 as well as the words of Jesus in the gospel, "Blessed is He who comes in the name of the Lord." It is sung/recited after the Preface of the Eucharistic Canon.

In Latin:

Sanctus, sanctus, sanctus,
Dominus Deus Sabaoth
Pleni sunt caeli et terra in gloria tua.
Hosanna in excelsis.
Benedictus qui venit in nomine Domini.
Hosanna in excelsis.

In English:

Holy, holy, holy,
Lord God of Hosts (the current English Mass translation says "God of power and might")
Heaven and earth are full of Your glory.
Hosanna in the highest.
Blessed is He who comes in the Name of the Lord.
Hosanna in the highest.

Needless to say, there are numerous settings for both the Latin and English texts. Countless classical composers have rendered the Sanctus a very familiar piece in high school repertoires.

I am not even going to go into the alleged quality or alleged lack thereof of the musical settings for the English translation that is currently used in the Mass. Wars have started over less.
