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 thy praises, O God: Father, Son, and Holy Spirit. Thou art 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. (1979 BCP)
