Who is not astounded when he sees, O holy martyrs, the good fight that you fought? Being in the body you conquered the bodiless enemy, confessing Christ and armed with the Cross. In this way justly you were revealed to be expellers of demons and enemies of barbaric powers. Intercede unceasingly for the salvation of our souls. For, like the three children in the fiery furnace, you did not endure your trials in the hope of a reward, but out of love for God, as you yourselves have declared: ‘For even if He does not deliver us, yet we will not for that reason deny Him as one who does not save’ (cf. Dan. 3:17-18).
