O Oriens or O Rising Dawn or Morning Star (December 21)
O Rising Dawn, (Jer 23:5; Zechariah 3:8; 6:12),
Radiance of the Light eternal (Habakkuk 3:4; Wisdom 7:26; Hebrews 1:3) and Sun of Justice (Malachi 3:20): * come, and enlighten those who sit in darkness and in the shadow of death (Ps 107:10; Lk 1:78).
