From December 21st Vespers, the Antiphon to the Magnificat
O Oriens,
splendor lucis aeternae,
et sol justitiae:
veni, et illumina
sedentes in tenebris,
et umbra mortis.
O Day-spring, O Morning Star, O Breaking Sun, O Son of Righteousness
splendor of the light eternal and bright sun of righteousness:
come and bring light to those who dwell in darkness
and walk in the shadow of death.
Amen. Come, Lord Jesus.
