1 O Holy Ghost, thou Fount of light,
Thy blessed radiance puts to flight
The darkness of the mind;
The pure are only pure through thee;
And thou the prisoner dost set free,
And cheer with light the blind.

2 Thy grace eternal truth instills,
The ignorant with knowledge fills,
Awakens those who sleep,
Inspires the tongue, informs the eye,
Expands the heart with charity,
And comforts all who weep.

3 Teach us to aim at heaven's high prize,
And for its glory to despise
The world and all below;
Cleanse us from sin, direct us right,
Illume us with thy heavenly light,
Thy peace on us bestow.

4 Lord of all sanctity and might,
Eternal thou and infinite,
The life of earth and heaven;
To thee the High and Holy One,
To thee, with Father, and with Son,
Be praise and glory given.
