Irmos: With Thy divine light illumine the souls of those who with love rise at dawn unto Thee, I pray Thee, O Good One, that they may know Thee, O Word of God, to be the true God Who calleth all forth from the darkness of sin.
Lifting thy mind to the undefiled good, O saint of Christ, by thy way of life thou didst show thyself to be alien to the things that are in the world, O Isaac, and dost teach all to disdain that which is corruptible, and in nowise to desire those things that are perishable.
Theotokion: Eating of the tree in Eden through the wicked treachery of the serpent showed me to be mortal; but thou, having given birth to Christ, the Bestower of life, hast brought me to life, O thou who alone art full of God’s grace.
With torrents of tears, O father, thou didst utterly dry up the depths of pleasures; and with the outpourings of thy doctrines thou hast flooded the torrents of heresies, O blessed one.
Irmos: Wherefore hast Thou turned Thy face from me, O Light never-waning? And why hath a strange darkness covered me, wretch that I am? But turn me, and guide my steps to the light of Thy commandments, I pray.
Thou wast shown to be a describer and model of the angelic life, O divinely wise Isaac; wherefore, the grace of the Spirit hath shown thee to be a divine pastor and a God-bearing hierarch of the Church of Christ.
Theotokion: Slain by the deception and delusion of the serpent, O all-pure one, I flee unto thee who gavest birth to eternal Life. Enliven my mind by thy vivifying help, and guide me to a blameless life.
Thy mind, illumined by striving toward God, O father Ephraim, began to enjoy the full vision of God, receiving immaterial revelation as a mirror of the divine Spirit.
Having been inducted into the divine mysteries because of the purity of thy way of life, O God-bearer, thou didst do yet greater deeds, O divine Isaac, archpastor of Nineveh, explaining the words of the Gospel to all, and cleansing the wounds of their souls.
Thou didst truly become a temple holding the Trinity and adorned with grace, with the radiance of pure virtues and the fullness of teachings, O father.
