I believe that's Ἀληθῶς ανέστη...

     'The mystery of the incarnation of the Logos is the key to all the inner symbolism and typology in the Scriptures, and in addition gives us knowledge of created things, both visible and invisible. He who apprehends the mystery of the cross and the burial apprehends the inward essences of created things; while he who is initiated into the inexpressible power of the resurrection apprehends the purpose for which God first established everything,' St. Maximus the Confessor, Centuries on Theology and Economy, I.66.
