This magnificent icon of the Virgin Theotokos and Christ Child appears above the apse of the Great Church of Constantinople, Hagia Sophia (today preserved as the Ayasofya museum in Istanbul).
The featured prayer is the opening of the long, beautiful Compline supplication to the Theotokos.
Take a minute after reading this prayer to ponder the theological depth of these words in particular: “O undefiled, untainted, uncorrupted, most pure, chaste Virgin, thou Bride of God. . . who. . . hast linked the apostate nature of our race with the heavenly. . .”
