Irmos: The unoriginate King of glory, before Whom the hosts of heaven tremble, hymn, ye priests, and exalt supremely for all ages!
Him Who showed forth Isaacius as a champion of the Orthodox Faith do ye hymn, O priests; ye people, exalt Him supremely forever.
Theotokion: The Stone of life was cut from thee without the aid of man’s hands, as is written, O all-holy and pure one: God Whose good pleasure it was to dwell within thee.
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.
