Wa Halalela - Sanctus

This Sanctus is sung by the North Western Catholic Deanery Choir in the Sesotho language.

Holy, Holy, Holy Lord God of hosts.
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.

Sanctus, Sanctus, Sanctus
Dominus Deus Sabaoth.
Plenisuntcæli et terra gloria tua.
Hosanna in excelsis.
Benedictus qui venit in nomine Domini.
Hosanna in excelsis.
Sanctus, Sanctus, Sanctus, Dominus Deus Sabaoth.
Plenisuntcæli et terra maiestatisgloriætuæ.

The Sanctus is the last part of the Preface in the Mass, sung in practically every rite by the people (or choir).
Now the center and summit of the entire celebration begins: namely, the Eucharistic Prayer, that is, the prayer of thanksgiving and sanctification. The priest invites the people to lift up their hearts to the Lord in prayer and thanksgiving; he unites the congregation with himself in the prayer that he addresses in the name of the entire community to God the Father through Jesus Christ in the Holy Spirit. Furthermore, the meaning of the Prayer is that the entire congregation of the faithful should join itself with Christ in confessing the great deeds of God and in the offering of Sacrifice. The Eucharistic Prayer demands that all listen to it with reverence and in silence.
79. The chief elements making up the Eucharistic Prayer may be distinguished in this way:
a. Thanksgiving (expressed especially in the Preface): In which the priest, in the name of the entire holy people, glorifies God the Father and gives thanks for the whole work of salvation or for some special aspect of it that corresponds to the day, festivity, or season.
b. Acclamation: In which the whole congregation, joining with the heavenly powers, sings the Sanctus. This acclamation, which is part of the Eucharistic Prayer itself, is sung or said by all the people with the priest.
