Irmos: Overwhelming power once laid low the whole army of Pharaoh in the deep, and the incarnate Word hath destroyed pernicious sin. All-glorious is the Lord, for gloriously hath He been glorified.
Having crowned thy life with divine virtues, O venerable Cassian, thou didst depart unto God. Him do thou beseech, we pray, that deliverance from transgressions be granted us who commemorate thy holy repose with faith.
Theotokion: We all know thee, O pure one, as her who conceived in the womb; for in manner past understanding thou gavest birth to God Who had clothed Himself in mortal flesh, the all-glorious Lord Who hath illumined the company of the venerable. Gloriously hath He been glorified!
Wholly inclined toward the God of all, O right glorious one, thou didst turn away from passionate thoughts, and, deified by partaking of the immaterial, thou becamest light, hymning the all-glorious Lord Who glorified thee.
In thy divine teachings thou wast a physician for souls, O Cassian, and, setting aright the thoughts of monastics by grace, thou didst lead them to life everlasting. Wherefore, we all honor thee with love.
