Troparion — Tone 3
You brought joy to the Orthodox / and shame to the defenders of heresy, / for you confirmed what the Fathers of the Fourth Council had correctly taught. / Glorious martyr Euphemia, fair virgin of Christ, / entreat Christ God to grant us His great mercy.
Kontakion — Tone 2
For the sake of Christ your Bridegroom / you underwent struggles in both martyrdom and faith. / Now intercede with the Mother of God / that heresies and the insolent enemies of the Orthodox be placed underfoot. / You received and guarded that which was defined by the six hundred and thirty God-bearing Fathers, / all-praised Euphemia.
