O Morning Star,
splendour of light eternal and sun of righteousness:
Come and enlighten those who dwell in darkness
and the shadow of death.

The photo is of the inside of the Armenian Cathedral of St James the Greater and St James the Less, Jerusalem. Light penetrates the dark from above. The inside of the great dome is in the design of a six-sided Star of David.
