There is another evil of the day, which I would were sufficient for it. For by eating and drinking we repair the daily decays of our body, until Thou destroy both belly and meat, when Thou shalt slay my emptiness with a wonderful fulness, and clothe this incorruptible with an eternal incorruption. But now the necessity is sweet unto me, against which sweetness I fight, that I be not taken captive; and carry on a daily war by fastings; often bringing my body into subjection; and my pains are removed by pleasure. For hunger and thirst are in a manner pains; they burn and kill like a fever, unless the medicine of nourishments come to our aid. Which since it is at hand through the consolations of Thy gifts, with which land, and water, and air serve our weakness, our calamity is termed gratification.
This hast Thou taught me, that I should set myself to take food as physic. But while I am passing from the discomfort of emptiness to the content of replenishing, in the very passage the snare of concupiscence besets me. For that passing, is pleasure, nor is there any other way to pass thither, whither we needs must pass. And health being the cause of eating and drinking, there joineth itself as an attendant a dangerous pleasure, which mostly endeavours to go before it, so that I may for her sake do what I say I do, or wish to do, for health's sake. Nor have each the same measure; for what is enough for health, is too little for pleasure. And oft it is uncertain, whether it be the necessary care of the body which is yet asking for sustenance, or whether a voluptuous deceivableness of greediness is proffering its services. In this uncertainty the unhappy soul rejoiceth, and therein prepares an excuse to shield itself, glad that it appeareth not what sufficeth for the moderation of health, that under the cloak of health, it may disguise the matter of gratification. These temptations I daily endeavour to resist, and I call on Thy right hand, and to Thee do I refer my perplexities; because I have as yet no settled counsel herein.
