O Salutaris Hostia lyrics

O Salutaris Hostia
Quae caeli pandis ostium:
Bella premunt hostilia,
Da robur, fer auxilium.

Uni trinoque Domino
Sit sempiterna gloria,
Qui vitam sine termino
Nobis donet in patria.
Amen.
[ Lyrics from: http://www.lyricsmode.com/lyrics/b/beth_nielsen_chapman/o_salutaris_hostia.html ]
O saving Victim, opening wide
The gate of heaven to all us below:
Our foes press on from every side;
Thine aid supply, Thy strength bestow.

To Thy great Name be endless praise,
Immortal Godhead, One in Three!
O grant us endless length of days
With Thee in our true country.
Amen.
