Listen to me now: stand together in peace. Look after one another, and show concern for another’s needs. By eating too much, some of you have brought sickness on your bodies and ruined them, while the limbs of others, who have nothing to eat, waste away for lack of food.… And you who have become old in spirit: you are already dying. Your soft living and constant doubts have brought you to this point. You are enervated by the affairs of daily life; you have fallen into lethargy; you are like old men who have given up hope of regaining strength and expect nothing but to fall asleep… But don’t give up hope. Awake and repent, and you will all be quite new again.
