God honored you with the gift, why disgrace yourself with the excess thereof? Hear what Paul says, “Use a little wine for your stomach's sake, and your frequent infirmities.” But if that saint, even when oppressed with disease, and enduring successive sicknesses, partook not of wine, until his Teacher suffered him; what excuse shall we have, who are drunken in health? To him indeed He said, “Use a little wine for your stomach's sake;” but to each of you who are drunken, He will say, “Use little wine, for your fornications, your frequent filthy talking, for the other wicked desires to which drunkenness is wont to give birth.” But if you are not willing, for these reasons, to abstain; at least on account of the despondencies which come of it, and the vexations, do ye abstain. For wine was given for gladness, “Yea, wine,” so it is said, “makes glad the heart of man:” but you mar even this excellence in it. For what kind of gladness is it to be beside one's self, and to have innumerable vexations, and to see all things whirling round, and to be oppressed with giddiness, and like those that have a fever, to require some who may drench their heads with oil?
6. These things are not said by me to all: or rather they are said to all, not because all are drunken, God forbid; but because they who do not drink take no thought of the drunken. Therefore even against you do I rather inveigh, that are in health; since the physician too leaves the sick, and addresses his discourse to them that are sitting by them. To you therefore do I direct my speech, entreating you neither to be at any time over-taken by this passion, and to draw up as by cords those who have been so overtaken, that they be not found worse than the brutes. For they indeed seek nothing more than what is needful, but these have become even more brutish than they, overpassing the boundaries of moderation. For how much better is the ass than these men? How much better the dog! For indeed each of these animals, and of all others, whether it need to eat, or to drink, acknowledges sufficiency for a limit, and goes not on beyond what it needs; and though there are innumerable persons to constrain, it will not endure to go on to excess.
In this respect then we are worse even than the brutes, by the judgment not of them that are in health only, but even by our own. For that you have judged yourselves to be baser than both dogs and asses, revealed to Peter, He does hereby again confirm. And neither at this did He stop, but by His very condescension declares this self-same truth; an instance of exceeding wisdom.
