When you attend Presanctified Liturgy tonight, listen for this prayer:
O Joyful Light of the Holy Glory of the Father immortal,
the heavenly, holy, Blessed One; O Jesus Christ.
Now that we have reached the setting of the sun
and see the evening light, we sing to God, +Father, Son and Holy Spirit.
It is fitting at all times to raise a song of praise in measured melody to You,
O Son of God, the giver of life. Therefore the universe sings your glory.
Priest: Wisdom! Be attentive! The Light of Christ shines upon everyone!
People: Make three great prostrations in silence.
Did you know that this is a very ancient hymn, and that it is considered the very oldest song, besides those written in scripture, that Christians still sing today?
