O TRINITY, O blessèd light, O unity, most principal,
The fiery sun now leaves our sight:
Cause in our hearts Thy beams to fall.

2 Let us with songs of praise divine At morn and evening Thee implore,
And let our glory, bowed to Thine, Thee glorify for evermore.
3 To God the Father, glory great, And glory to His only son,
And to the Holy paraclete,
Both now and still while ages run. Amen.
