To Florus 2.223

He says that we died to sin at the time when, to receive the gift of forgiveness, we professed our renunciation of the world and all sins. Remembering the gift, we should therefore live in a way that shows we have been buried with Christ and visibly bear his resurrection in holiness. Just as, after rising from the dead, he undergoes no bodily weakness or scourging, so we too should strive to be invulnerable to all sins and vices. ‘For if we have been planted together in the likeness of his death, we shall also share his resurrection, knowing that our old self was crucified with him so that the body of sin might be destroyed, so that we no longer serve sin. For the one who has died has been justified from sin’ (Romans 6:5–7). He binds believers with clear reasoning. If you wish, he says, to share his resurrection, imitate the power of his death too, so that, dead to vices, you may live in virtue. You will share that happiness if you bear the image of his death by dying to sins. Our old self should be shown nailed to his cross, to destroy the body of sin through the courage of suffering. By ‘body of sin,’ according to his customary usage, Paul means vices, not the substance of flesh. For he continues: ‘So that the body of sin might be destroyed, so that we no longer serve sin. For the one who has died has been justified from sin.’
