Tantum Ergo

Tantum ergo Sacramentum
Veneremur cernui
Et antiquum documentum
Novo cedat ritui
Praestet fides supplementum
Sensum defectui

Genitori, Genitoque
Laus et jubilatio
Salus, honor, virtus quoque
Sit et benedictio
Procedenti ab utroque
Compar sit laudatio. A-men

Translation:

Thus, a so important sacrament
We would bended adore.
And the Old Testament
Transfers into the new solemnity
It is a supplement to the believers,
To a flagged spirit.

To the Creator and his creation
Be praise and joy,
Hail and honor, perfectness too
And blessings.
Proceeding from both sides,
The loved one must be praised. Amen.
