On “Lord, I have cried…”, 6 stichera: 3 of the feast, in Tone I: Spec. Mel.: “Joy of the ranks of heaven…”—
Troparion of the martyr, in Tone IV—
He Who of old spake with Moses on Mount Sinai in images, saying: “I am God Who am!” today, transfigured on Mount Tabor, showeth forth the Prototype, shining with rays of splendor. Wherefore, O Christ, I magnify Thy power!
Glory…, Now & ever…: troparion of the feast, in Tone VII—
Taking with Thee Thy favorite disciples, O Christ, Peter, James and John, Thou didst willingly lead them up to the mountain, showing them an awesome wonder: the everlasting and unbearable magnificence of Thy divine arrival from afar.
The apostles of old, trembling at Thine unapproachable advent, O Christ, falling prostrate on the ground, marvelled at the power of Thy divinity, which shone forth more brightly than the sun, O Good One, with Thine ineffable might.
And 3 stichera of the martyr, in the same tone: Spec. Mel.: “Thou hast given a sign…”—
Thou didst traverse well the abyss of suffering, thy sail filled with the breath of the Spirit; and thou didst make thy way to the calm haven of the kingdom of God, wherein thou hast received rich reward for thy pangs, and standest with the angels before the Master of creation, O blessed one.
Clad in a purple robe dyed in thy blood, O glorious one, and crowned with the wreath of victory by the hand of the Creator of life, thou dwellest in the heavens, reigning with the most Compassionate One. Wherefore, we call thee blessed, as a true martyr and a servant of the Word, the confirmation of the Faith.
As a minister of the mysteries of the Master, the wondrous Euplus brought himself forth like an innocent lamb; and, beheaded with the sword, he became a divine lamb, a sacrifice of sweet savor. We therefore call him blessed, celebrating today, in sacred manner, his hallowed suffering, O ye who love the martyrs.
Glory…, Now & ever…, in the same tone—
The mountain which before was dark and gloomy is now honorable and holy, for thereon did Thy feet stand, O Lord; for in the latter days Thou didst make manifest the hidden, preëternal mystery, Thine awesome transfiguration, to Peter, John and James. But they, unable to endure the radiance of Thy countenance and the brightness of Thy raiment, fell prostrate on the ground and covered themselves. And, seized with terror, they marvelled, beholding Moses and Elijah conversing with Thee as they stood with Thee; and the voice of the Father bore witness, saying: “This is My beloved Son in Whom I am well pleased: Him do ye obey! He Will grant the world great mercy!”
At the aposticha, these stichera of the feast, in Tone II: Spec. Mel.: “O house of Ephratha…”—
Desiring to transform the nature of Adam, Christ doth now ascend Mount Tabor, revealing His divinity to the disciples.
Stichos: Thine are the heavens, and Thine is the earth.
The thrice-radiant light of Thy divine glory shone forth ineffably on Mount Tabor, O Savior, and hath illumined all things.
Stichos: Tabor and Hermon shall rejoice in Thy name.
The disciples, beholding the transformation of Thy garments and of Thy whole body, O Word, fell prostrate, chanting.
Glory…, Now & ever…, in Tone IV—
Transfigured on the high mountain, the Savior, having with Him His preëminent disciples, shone forth most wondrously, showing them forth as illumined by the loftiness of the virtues and as ones vouchsafed divine glory. Moses and Elijah, who spake with Christ, showed that He hath authority over the living and the dead, and that He is the God Who of old spake through the law and the prophets. Of Him was the voice of the Father heard saying from the cloud of light: “Him do ye obey, Who through the Cross made hell captive and granteth life everlasting to the dead!”
In his suffering, O Lord, Thy martyr Euplus received an imperishable crown from Thee, our God; for, possessed of Thy might, he set at nought his tormenters, and crushed the feeble audacity of the demons. Through his supplications, save Thou our souls.
Thou wast transfigured on the mountain, O Christ God, Who didst show Thy glory to Thy disciples as far as they could bear it. May Thine ever-existing light shine forth also upon us sinners through the prayers of the Theotokos. O Bestower of light, glory be to Thee!
