O DAWN OF THE EAST, brightness of light eternal, and Sun of Justice: COME, and enlighten those who sit in darkness and in the shadow of death. Amen. "O Oriens..."
Isaiah 9:1: "The people who walked in darkness have seen a great light. Upon those who dwelt in the land of gloom a light has shone".
Malachi 3:20: "For you who fear my name, there will arise the sun of justice with its healing rays".
2 Peter 1:19: "Keep your attention closely fixed on it, as you would on a lamp shining in a dark place, until the first streaks of dawn appear and the morning star rises in your heart".
This title is variously translated "morning star", "Dayspring", "rising sun", "radiant dawn", "and orient". It develops the previous antiphon. It’s my favourite one I think because it expresses beautifully the idea of light shattering the darkness of night, of sin and death, of sickness and despair, with its brightness bringing healing and warmth to cold hearts. Jesus is indeed the true light in our darkness but sometimes we seem to prefer the dark!
