An evening prayer (4th century)*
O GLADDENING light of the holy glory of the immortal, heavenly, holy, blessed Father, O Jesus Christ!
Now that we are come at the setting of the sun and behold the evening light, We sing the praise of God, Father, Son and Holy Spirit.
It is right at all times to hymn thee with songs of praise, O Son of God, Giver of life: wherefore all the world glorifieth thee.
* From the Greek, meaning ‘Cheerful or cheering light’. The prayer is found in the ‘Apostolic Constitutions’, compiled in Syria in about 375, though much of the material is a great deal older. Some liturgical books attribute it to St Sophronius of Jerusalem (560-638), but he was simply an editor, not the original author. ‘Hail Gladdening Light’ is sung every evening at Vespers.
