Troparion for the Feast:

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!

Kontakion for the Feast:

Today You have shown forth to the world, O Lord,
and the light of Your countenance has been marked on us.
Knowing You, we sing Your praises.
You have come and revealed Yourself,
O unapproachable Light.
