Troparion

The image of Thy Cross hath now shone forth more brightly than the sun,
and Thou hast extended it from the holy mountain to the place of the skull,
and therein hast revealed Thy might, O Savior.
Strengthening all faithful Orthodox Christians thereby, O Christ God,
save them ever in peace, and by the supplications of the Theotokos do Thou also save us.
