Преобразился еси на горе, Христе Боже...

For He received from God the Father honor and glory when such a voice came to Him from the Excellent Glory: "This is My beloved Son, in whom I am well pleased."
2 Peter 1:17

You were transfigured on the Mount, Christ God revealing Your glory to Your disciples, insofar as they could comprehend. Illuminate us sinners also with Your everlasting light, through the intercessions of the Theotokos. Giver of light, glory to You.
