Ὅστις σῶμα ἐνίκησεν, οὗτος φύσιν ἐνίκησεν· ὁ δὲ (τὴν) φύσιν νικήσας, οὗτος ὑπὲρ φύσιν ἐγένετο.
He who has conquered his body has conquered nature; and he who has conquered nature has
certainly risen above nature.
St. John Climacus, The Ladder of Divine Ascent, Step 15:7
St. James the Ascetic's scroll is probably an extract from his personal prayer from within the sepulcher where he spent 15 years:
Ὁ Θεός ὁ τοὺς κατεῤῥαγμένους ἐξανιστῶν καὶ παρασκευάζων τοὺς ἐχθροὺς ἡμῶν κόπτεσθαι ἡνίκα ἄν μετανοῶμεν
God, who rises the contrite and provides for our enemies, mourns whether we repent (or not)...or something like that
