Venerable John Cassian the Roman - Troparion & Kontakion
Troparion — Tone 8
Having been purified through fasting, / you attained the knowledge of wisdom from the God-bearing Fathers who lived in the desert, / and learned to restrain the passions. / Therefore, by your prayers, grant that our flesh may be obedient to our spirit; / for you, O Venerable Cassian, are the teacher of all those in Christ who glorify your memory.

As a venerable monk, O John Cassian, / you consecrated your life to God, and radiant with virtue, / you shone like the sun with the splendor of your divine teachings, / always enlightening the hearts of all who honor you. / Earnestly entreat Christ on behalf of those who praise you with fervent love.
