In her solitude, Christina began to wonder who had created this beautiful world. From her room she was delighted by the stars of the heavens and she constantly came back to the thought about the Creator of all the world. She was convinced, that the voiceless and inanimate idols in her room could not create anything, since they themselves were created by human hands. She began to pray to the One God with tears, entreating Him to reveal Himself. Her soul blazed with love for the Unknown God, and she intensified her prayer all the more, and combined it with fasting.
One time Christina was visited by an angel, who instructed her in the true faith in Christ, the Savior of the world. The angel called her a bride of Christ and told her about her future suffering. The holy virgin smashed all the idols standing in her room and threw them out the window. In visiting his daughter Christina's father, Urban, asked her where all the idols had disappeared. Christina was silent. Then, having summoned the servants, Urban learned the truth from them.

Apolytikion in the Fourth Tone O Lord Jesus, unto Thee Thy lamb doth cry with a great voice: O my Bridegroom, Thee I love; and seeking Thee, I now contest, and with Thy baptism am crucified and buried. I suffer for Thy sake, that I may reign with Thee; for Thy sake I die, that I may live in Thee: accept me offered out of longing to Thee as a spotless sacrifice. Lord, save our souls through her intercessions, since Thou art great in mercy.
Kontakion in the Fourth Tone O dove of golden wings, thou shonest like lightning, and flewest up unto the height of the Heavens, august Christina; therefore we all celebrate thy glorious festival, as we faithfully rev'rence the worshipful shrine wherein thy pure relics are treasured, whence thou dost truly well forth unto all divine cures both for the body and for the soul.
