Apolytikion of Great Martyr Euphemia 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 Great Martyr Euphemia in the Fourth Tone
Thou strovest valiantly in thy sacred contest; and even after death, thou makest us holy with streams of healings, O all-famed Euphemia. For this cause we venerate thy most holy dormition and with faith we stand before thine all-ven'rable relics, that we be freed from illness of the soul and also draw forth the grace of thy miracles.
