Resurrectional Apolytikion
Ότε κατήλθες πρός τόν θάνατον, η Ζωή η αθάνατος, τότε τόν Άδην ενέκρωσας τή αστραπή τής θεότητος, ότε δέ καί τούς τεθνεώτας εκ τών καταχθονίων ανέστησας, πάσαι αι Δυνάμεις τών επουρανίων εκραύγαζον, Ζωοδότα Χριστέ ο Θεός ημών δόξα σοι.

When You descended to death, O Immortal Life, then, the light of Your divinity destroyed Hades. When You raised the dead from the depths of darkness, all the heavenly powers cried out, "Glory to You our Christ, the Giver of Life." -Translation by Narthex Press

Apolytikion of the Church
Third Tone

The world has found in you a great champion in time of peril, as you emerged the victor in routing the barbarians. For as you brought to naught the boasts of Lyaios, imparting courage to Nestor in the stadium, in like manner, holy one, great Martyr Demetrios, invoke Christ God for us, that He may grant us His great mercy.

O Protection of Christians that cannot be put to shame, mediation unto the creator most constant: O despise not the voices of those who have sinned; but be quick, O good one, to come unto our aid, who in faith cry unto thee: Hasten to intercession and speed thou to make supplication, O thou who dost ever protect, O Theotokos, them that honor thee. - Translation by Holy Transfiguration Monastery
