XX. Now, if some one should find that more wantonness arose in his flesh from eating fish than from eating eggs and meat, let him eat meat and not fish. Again, if he find that his head becomes confused and crazed or his body and stomach injured through fasting, or that it is not needful to kill the wantonness of his flesh, he shall let fasting alone entirely, and eat, sleep, be idle as is necessary for his health, regardless whether it be against the command of the Church, or the rules of monastic orders: for no commandment of the Church, no law of an order can make fasting, watching and labor of more value than it has in serving to repress or to kill the flesh and its lusts. Where men go beyond this, and the fasting, eating, sleeping, watching are practised beyond the strength of the body, and more than is necessary to the killing of the lust, so that through it the natural strength is ruined and the head is racked; then let no one imagine that he has done good works, or excuse himself by citing the commandment of the Church or the law of his order. He will be regarded as a man who takes no care of himself, and, as far as in him lies, has become his own murderer. For the body is not given us that we should kill its natural life or work, but only that we kill its wantonness; unless its wantonness were so strong and great that we could not sufficiently resist it without ruin and harm to the natural life. For, as has been said, in the practice of fasting, watching and labor, we are not to look upon the works in themselves, not on the days, not on the number, not on the food, but only on the wanton and lustful Adam, that through them he may be cured of his evil appetite. [Sidenote: Foolish Fasting and Foolish Neglect of Fasting] XXI. From this we can judge how wisely or foolishly some women act when they are with child, and how the sick are to be treated. For the foolish women cling so firmly to their fasting that they run the risk of great danger to the fruit of their womb and to themselves, rather than not to fast when the others fast. They make a matter of conscience where there is none, and where there is matter of conscience they make none. This is all the fault of the preachers, because they continually prate of fasting, and never point out its true use, limit, fruit, cause and purpose. So also the sick should be allowed to eat and to drink every day whatever they wish. In brief, where the wantonness of the flesh ceases, there every reason for fasting, watching, laboring, eating this or that, has already ceased, and there no longer is any binding commandment at all.
