Theodosia, Virgin-Martyr of Constantinople
The Righteous Martyr Theodosia, having Constantinople as her homeland, struggled in asceticism in her own convent, which was located in that same imperial city. Filled with zeal for the veneration of the holy icons, she withstood Emperor Leo the Isaurian's impious command that the icons be destroyed. She received the martyr's crown when a soldier of the imperial guard plunged a ram's horn through her throat, about the year 717.
Apolytikion of Virgin Martyr Theodosia of Constantinople 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 of Virgin Martyr Theodosia of Constantinople in the Second Tone
Through labours hast thou inherited life free of pain; with streams of thy blood, O all-praised maiden, thou didst drown the vile lion, who is the most abhorrent enemy of Christ's Church. As thou now rejoicest with Christ, unceasingly pray thou in our soul's behalf.
