Troparion — Tone 8
O Champion of Orthodoxy, teacher of purity and of true worship, / The enlightener of the universe and the adornment of the Hierarchs: / O all-wise Father Cosmas, Your teachings have gleamed with light upon all things. / Intercede before Christ our God to save our souls!
Troparion — Tone 4
Though in the flesh, you were zealous to emulate the choirs of heaven, / And while on earth you composed hymns to God in the highest, / Like a harp of holy wisdom, / With enlightened understanding you hymned God the Word. / O divinely inspired Cosmas, we praise you with hymns!
Kontakion — Tone 2
O God-inspired Cosmas, you adorned yourself with virtues, / Adorning the Church of Christ with the rich splendor of your hymns. / Intercede with the Lord that He may deliver us from the snares of our enemies! / We cry out to you: Rejoice, O holy and blessed Father!
