Troparion — Tone 7

You were transfigured on the mountain, O Christ God, / revealing Your glory to Your disciples as far as they could bear it. / Let Your everlasting Light also shine upon us sinners, / through the prayers of the Theotokos. / O Giver of Light, glory to You!

Kontakion — Tone 7

On the Mountain You were Transfigured, O Christ God, / and Your disciples beheld Your glory as far as they could see it; / so that when they would behold You crucified, / they would understand that Your suffering was voluntary, / and would proclaim to the world, / that You are truly the Radiance of the Father!
