“When Thou, O Lord, wast baptized in the Jordan, the worship of the Trinity was made manifest! For the voice of the Father bare witness to Thee, and called Thee His beloved Son! And the Spirit, in the form of a dove, confirmed the truthfulness of His word. O Christ our God, who hast revealed Thyself and hast enlightened the world, glory to Thee!”
(Troparion of Epiphany)
