The divine law, then, while keeping in mind all virtue, trains man especially to self-restraint, laying this as the foundation of the virtues; and disciplines us beforehand to the attainment of self-restraint by forbidding us to partake of such things as are by nature fat, as the breed of swine, which is full-fleshed. For such a use is assigned to epicures. It is accordingly said that one of the philosophers, giving the etymology of ὗς (sow), said that it was θύς, as being fit only for slaughter (θύσιν) and killing; for life was given to this animal for no other purpose than that it might swell in flesh. Similarly, repressing our desires, it forbade partaking of fishes which have neither fins nor scales; for these surpass other fishes in fleshiness and fatness. From this it was, in my opinion, that the mysteries not only prohibited touching certain animals, but also withdrew certain parts of those slain in sacrifice, for reasons which are known to the initiated. If, then, we are to exercise control over the belly, and what is below the belly, it is clear that we have of old heard from the Lord that we are to check lust by the law.
