This is not accomplished with comfortable, pleasant days, but here we must hurt our nature and let it be hurt. Here begins the strife between the spirit and the flesh; here the spirit resists anger, lust, pride, while the flesh wants to be in pleasure, honor and comfort. Of this St. Paul says, Galatians v, "They that are our Lord Christ's have crucified the flesh with its affections and lusts." Then follow the good works, -- fasting, watching, labor, of which some say and write so much, although they know neither the source nor the purpose of these good works.
Therefore we will now also speak of them.
XVIII. This rest, namely, that our work cease and God alone work in us, is accomplished in two ways. First, through our own effort, secondly, through the effort or urging of others.
Our own effort is to be so made and ordered that, in the first place, when we see our flesh, senses, will and thoughts tempting us, we resist them and do not heed them, as the Wise Man says:
"Follow not thine own desires." And Moses, Deuteronomy xii: "Thou shalt not do what is right in thine own eyes."Here a man must make daily use of those prayers which David prays: "Lord, lead me in Thy path, and let me not walk in my own ways," and many like prayers, which are all summed up in the prayer, "Thy kingdom come." For the desires are so many, so various, and besides at times so nimble, so subtile and specious, through the suggestions of the evil one, that it is not possible for a man to control himself in his own ways. He must let hands and feet go, commend himself to God's governance, and entrust nothing to his reason, as Jeremiah says, "O Lord, I know that the way of man is not in his own power." We see proof of this, when the children of Israel went out of Egypt through the Wilderness, where there was no way, no food, no drink, no help. Therefore God went before them, by day in a bright: cloud, by night in a fiery pillar, fed them with manna from heaven, and kept their garments and shoes that they waxed not old, as we read in the Books of Moses. For this reason we pray: "Thy kingdom come, that Thou rule us, and not: we ourselves," for there is nothing more perilous in us than our reason and will. And this is the first and highest work of God in us and the best training, that we cease from our works, that we let our reason and will be idle, that we rest and commend ourselves to God in all things, especially when they seem to be spiritual and good.
XIX. After this comes the discipline of the flesh, to kill its gross, evil lust, to give it rest and relief. This we must kill and quiet with fasting, watching and labor, and from this we learn how much and why we shall fast, watch and labor.
There are, alas! many blind men, who practise their castigation, whether it be fasting, watching or labor, only because they think these are good works, intending by them to gain much merit. Far blinder still are they who measure their fasting not only by the quantity or duration, as these do, but also by the nature of the food, thinking that it is of far greater worth if they do not eat meat, eggs or butter. Beyond these are those who fast according to the saints, and according to the days; one fasting on Wednesday, another on Saturday, another on St. Barbara's day, another on St. Sebastian's day, and so on. These all seek in their fasting nothing beyond the work itself: when they have performed that, they think they have done a good work. I will here say nothing of the fact that some fast in such a way that they none the less drink themselves full; some fast by eating fish and other foods so lavishly that they would come much nearer to fasting if they ate meat, eggs and butter, and by so doing would obtain far better results from their fasting. For such fasting is not fasting, but a mockery of fasting and of God.
Therefore I allow everyone to choose his day, food and quantity for fasting, as he will, on condition that he do not stop with that, but have regard to his flesh; let him put upon it fasting, watching and labor according to its lust and wantonness, and no more, although pope, Church, bishop, father-confessor or any one else whosoever have commanded it. For no one should measure and regulate fasting, watching and labor according to the character or quantity of the food, or according to the days, but according to the withdrawal or approach of the lust and wantonness of the flesh, for the sake of which alone the fasting, watching and labor is ordained, that is, to kill and to subdue them. If it were not for this lust, eating were as meritorious as fasting, sleeping as watching, idleness as labor, and each were as good as the other without all distinction.
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.
