Commemorated on January 18
Troparion & Kontakion
Troparion — Tone 3
You shone forth with works of Orthodoxy and quenched all heresy, / and became victorious trophy-bearers, hierarchs Athanasius and Cyril. / You enriched all things with piety and greatly adorned the Church, / and worthily found Christ God, / who grants His great mercy to all.
Kontakion — Tone 4
Athanasius and Cyril, great hierarchs of true piety, and noble champions of the Church of Christ, / preserve all who sing: / “O Compassionate Lord, save those who honor You.”
