When You, O Lord were baptized in the Jordan / The worship of the Trinity was made manifest / For the voice of the Father bore witness to You / And called You His beloved Son. / And the Spirit, in the form of a dove, / Confirmed the truthfulness of His word. / O Christ, our God, You have revealed Yourself / And have enlightened the world, glory to You!
