Kontakion for the Holy Feast of Theophany. Mode 4. Original Melody.

You appeared to us on earth* today, O Master,* and Your light was signed on us * who cry aloud to You and say * with understanding, O Christ our God: You came and shone forth, O Light unapproachable.

The Oikos for the Feast

On Galilee of the Gentiles, on the region of Zebulòn and the land of Nephthalím, as the Prophet declared, a great light has shone, which is the Christ. Dark-dwellers have seen a radiant dawn shining out of Bethlehem, rather out of Mary, as the Lord—the Sun of Justice—breaks His rays o’er the whole of civilization. Come then, all unclothed offspring of Adam: let us put on Christ and thus keep warm. For, as a mantle for the denuded and a beacon to the be-darkened, You came and shone forth, O Light unapproachable.
