20 December – O Oriens (O Radiant Dawn)
O Day-Spring, radiant everlasting Light, and Sun of Righteousness: Come and enlighten those who sit in darkness and the shadow of death.
O come, thou Day-spring from on high,
And cheer us by thy drawing nigh;
Disperse the gloomy clouds of night,
And death’s dark shadow put to flight.
The people that walked in darkness, have seen a great light: to them that dwelt in the region of the shadow of death, light is risen.
For behold the day shall come kindled as a furnace: and all the proud, and all that do wickedly shall be stubble: and the day that cometh shall set them on fire, saith the Lord of hosts, it shall not leave them root, nor branch. But unto you that fear my name, the Sun of justice shall arise, and health in his wings: and you shall go forth, and shall leap like calves of the herd. And you shall tread down the wicked when they shall be ashes under the sole of your feet in the day that I do this, saith the Lord of hosts.
Luke 1:78, 79; Hebrews 1:3; John 1:4, 5; Titus 3:4; Luke 7:22; Ephesians 5:8-14.
