Venerable Isaac, Founder of Dalmátos Monastery at Constantinople - Troparion & Kontakion

Troparion — Tone 3

(Podoben: “The Divine Faith...”)
Appearing as an example of abstinence, and a support of the Church, / O Isaac, adornment of the Fathers, / your life was radiant with virtues, / and you clearly expounded the word of Orthodoxy. / O Venerable Father, entreat Christ God that He may grant us great mercy.

Kontakion — Tone 8

(Podoben: “As first-fruits...”)
As a faithful servant of God, you were inflamed with zeal for the Church of Christ, / holding the reins of the Emperor Valens, / you prophetically foretold His death in a fire because of his closure of the churches. / Therefore, always pray for us who honor you, O Venerable Father Isaac.
