O Oriens – St Thomas, Apostle
O morning star, 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.

Relevant verse in Veni, Veni Emmanuel:

O come, Thou Dayspring, come and cheer,
Our spirits by your advent here;
Disperse the gloomy clouds of night,
And death's dark shadows put to flight.

1 When the Lord restored the fortunes of Zion,*
we were like those who dream.
2 Then our mouth was filled with laughter, and our tongue with shouts of joy;
then it was said among the nations, ‘The Lord has done great things for them.’
3 The Lord has done great things for us,
and we rejoiced.
4 Restore our fortunes, O Lord,
like the watercourses in the Negeb.
5 May those who sow in tears
reap with shouts of joy.
6 Those who go out weeping, bearing the seed for sowing,
shall come home with shouts of joy, carrying their sheaves.
Psalm 126 New Revised Standard Version
