Having arrived from the confines of the wilderness, O venerable and holy one, thou didst make firm the Faith of Christ, scattering the assembly of heretics.
Thou wast in nowise ashamed to address the emperor as Nathan did David, O glorious one, desiring to make steadfast the Church of Christ.
Cast into the mire by the deceived, O all-praised and glorious one, thou didst shine forth like a pearl lustrous with the splendor of the Spirit.
Thou wast shown to be a noetic clarion, O father, summoning all as to battle, to stand against the hordes of the enemy with the help of Christ the Savior.
Thou wast shown to be a noetic ladder, O God-bearer, leading to the kingdom on high those who enter upon it with faith and are made steadfast in the Spirit by thy teachings.
Thou wast revealed as a mountain of doctrine by the love of the Master, O God-bearer, gathering into the Church of Christ all who have cleaved unto Him through the virtues.
As thou didst show forth thy life on earth as angelic, thou dost dance with the heavenly hosts.
Having first been a leader of monks from the desert, O divinely wise and glorious one, thou didst provide a model for those in the city.
Thy memory now doth truly gladden the hearts of those who hymn thee, O father Isaac.
Thou didst truly shine forth from the desert like a radiant star, and with thy doctrines didst drive away the night of heresy.
Holding the horse of Valens by the bridle, O all-praised one, thou didst denounce his bestial understanding, openly putting him to shame.
Thou didst expose thy head to the blows of a staff, O father, noetically holding Christ God to be the head of thy faith.
Through the knowledge of the Spirit thou didst foretell an abominable death for Valens, O wise one, and wast truly shown to be a glorious prophet.
With the winnowing-fan of the Faith thou didst gather the faithful in like wheat, O wise one, and by thy supplications thou didst burn up Valens like weeds in a bonfire.
Thou hast smoothed the tablets of the hearts of those who heed thee with faith, O divinely wise Isaac, engraving the image of Orthodoxy upon them.
O Lord God of our fathers, Who granted thy venerable one the words to upbraid the tyrant for his wickedness, blessed art Thou forever!
Dwelling gloriously in the splendid mansion of the righteous, O father, thou criest out to the Creator: Blessed art Thou forever, O Lord God of our fathers!
O honored father, cease thou never to entreat the Savior constantly in our behalf, that thy flock may be delivered from every misfortune and may receive life which cannot be taken away.
Him Who showed forth Isaac as a champion of the Orthodox Faith do ye hymn, O priests; ye people, exalt Him supremely forever.
Thou didst come forth from the wilderness as a noetic lamb, driving the wild beasts from the flock of Christ, and expelling them to dwell in empty places.
In thy meekness of spirit thou wast not daunted by the cruel and wicked wrath of Valens, O father, for the Spirit of truth was working within thee.
Thou didst mightily crush the powers of the ungodly with the strength of the divine Spirit.
With the bond of faith thou didst bind with bonds the heretical hordes.
O divinely wise Isaac, cease thou never to cause God to be mindful of our salvation.
