O Gracious Light Phos hilaron
O gracious Light,
pure brightness of the everliving Father in heaven,
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 your praises, O God: Father, Son, and Holy Spirit.
You 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.
(Evening Prayer in The Book of Common Prayer, p. 118 )
