On “Lord, I have cried…”, these stichera, in Tone II: Spec. Mel.: “When from the Tree…”—
Glory…, Now & ever…: Theotokion, in the same tone & melody—
Troparion, in Tone IV—
The Church of God bestowed thee upon the flock and reason-endowed sheep of Christ as an invincible champion, O blessed Eutychius, who drove therefrom the impious Nestorius, who in vain blasphemed the all-glorious and pure Mother of God, denying that she is in truth the Theotokos. Him didst thou reject.
Thou didst wisely guide thy flock to the grass of the right Faith, the living water of true wisdom, and beauteous verdure in pastures planted by God, to the food of incorruption which never faileth and never falleth away; and thy mouth overflowed with the divine words of eternal life and indestructible thought.
Cutting down the words of the heretics like roots and thorns with the scythe and plough of thy doctrine, thou didst fell their vile hearts and sow thy correction and judgment of the divine commandments; and having shown them to be fruitful, thou hast earned thy talant twofold and bearest it to thy Master.
Truly we have acquired no other mighty refuge and tower of strength, no other unassailable rampart than thee, O all-pure one. To thee do we flee, and to thee do we cry out: O Mistress, help us! Let us not perish! Show forth upon us thy grace, the glory of thy might and the magnitude of thy loving-kindness!
Stavrotheotokion—
Beholding knew not wedlock said, weeping: “O my sweet Child, wherefore hast Thou forsaken me who alone gave birth to Thee, O unapproachable Light of the all-unoriginate Father? Haste Thou and glorify Thyself, that they who glorify Thy divine sufferings may receive divine glory!”
The truth of things revealed thee to thy flock as a rule of faith, a model of meekness and teacher of abstinence. Wherefore, by humility thou hast acquired lofty things, and riches by poverty. O father Eutychius, entreat Christ God, that our souls be saved.
