If you would like to hear some of the Gregorian chant that accompanied it:
We praise thee, O God :
we acknowledge thee to be the Lord.
All the earth doth worship thee :
the Father everlasting.
To thee all Angels cry aloud :
the Heavens, and all the Powers therein.
To thee Cherubim and Seraphim :
continually do cry,
Holy, Holy, Holy :
Lord God of Sabaoth;
Heaven and earth are full of the Majesty :
of thy glory.
The glorious company of the Apostles : praise thee.
The goodly fellowship of the Prophets : praise thee.
The noble army of Martyrs : praise thee.
The holy Church throughout all the world :
doth acknowledge thee;
The Father : of an infinite Majesty;
Thine honourable, true : and only Son;
Also the Holy Ghost : the Comforter.
Thou art the King of Glory : O Christ.
Thou art the everlasting Son : of the Father.
When thou tookest upon thee to deliver man :
thou didst not abhor the Virgin's womb.
When thou hadst overcome the sharpness of death :
thou didst open the Kingdom of Heaven to all believers.
Thou sittest at the right hand of God : in the glory of the Father.
We believe that thou shalt come : to be our Judge.
We therefore pray thee, help thy servants :
whom thou hast redeemed with thy precious blood.
Make them to be numbered with thy Saints : in glory everlasting.
