Saint Leo the Great, Pope of Rome - Troparion & Kontakion

Troparion — Tone 3

You were the Church’s instrument / in strengthening the teaching of true doctrine; / you shone forth from the West like a sun dispelling the errors of the heretics. / Righteous Leo, entreat Christ God to grant us His great mercy.

Troparion — Tone 8

O Champion of Orthodoxy, and teacher of holiness, / The enlightenment of the universe and the inspired glory of true believers. / O most wise Father Leo, your teachings are as music of the Holy Spirit for us! / Pray that Christ our God may save our souls!

Kontakion — Tone 3

Seated upon the throne of the priesthood, glorious Leo, / you shut the mouths of the spiritual lions. / With divinely inspired teachings of the honored Trinity, / you shed the light of the knowledge of God upon your flock. / Therefore, you are glorified as a divine initiate of the grace of God.
