Holy and Glorious Great-martyr Demetrius the Myrrh-gusher of Thessalonica (306).
Verily, the inhabited world found thee a great succor in tribulations and a vanquisher of nations, O fight-bearing one. Wherefore, as thou didst demolish the arrogance of Lahosh, and on the battle-field didst hearten Nestor, beseech, O Saint, Christ God to grant us the Great Mercy.
+Troparion, Tone 3
Verily, God, O Demetrius, who granted thee invincible power hath touched the Church with the live coal of thy blood streams, preserving the city unbreached; for it is established by thee.
+Kontakion, Tone 2
