Venerable John of Damascus - Troparion & Kontakion
Troparion — Tone 8
Champion of Orthodoxy, teacher of purity and of true worship, / the enlightener of the universe and the adornment of hierarchs: / all-wise father John, your teachings have gleamed with light upon all things. / Intercede before Christ God to save our souls.
Kontakion — Tone 4
Let us sing praises to John, worthy of great honor, / the composer of hymns, the star and teacher of the Church, the defender of her doctrines: / through the might of the Lord’s Cross he overcame heretical error / and as a fervent intercessor before God / he entreats that forgiveness of sins may be granted to all.
