Troparion
When Thou, O Lord, wast baptized in the Jordan, the worship of the Trinity was made manifest; for the voice of the Father didst bear witness unto Thee, calling Thee His beloved Son. And the Spirit, in the form of a dove, didst confirm the truthfulness of His word. O Christ our God Who hast revealed Thyself and hast enlightened the world, glory to Thee!
Kontakion
Today Thou hast shown forth to the world, O Lord, and the light of Thy countenance hath been marked upon us. Knowing Thee, we sing Thy praises. Thou hast come and revealed Thyself, O unapproachable Light.
