O Gracious Light

O Gracious Light,
pure brightness of the everlasting Father in heav'n.
O Jesus Christ, holy and blessed!
Now as we come to the setting of the sun,
and our eyes behold the vesper light, we sing praises, O God:
Father, Son and Holy Spirit.
Thou are worthy at all times
to be praised by happy voices, O Son of God, O Giver of life,
and to be glorified through all the worlds.
