Troparion — Tone 3
The entire world has found you to be a great champion in times of peril; / for you put the heathen to flight, O victorious one. / As you brought to naught the boasts of Lyaeus, and gave courage to Nestor in the stadium, / in the same way, O Holy Great Martyr Dēmḗtrios, / entreat Christ God, that He grant us great mercy.
Kontakion — Tone 2
(The Original Melody)
God, Who has given you invincible strength, Dēmḗtrios, / has adorned the Church with the royal purple of the streams of your blood, / and has kept your city unharmed, / for you are its support.
