For those souls which are devoid of flesh and of the body, remaining undisturbed in the theatre of the universe, occupied in seeing and hearing divine things, of which an insatiable desire has seized them, enjoy a pleasure to which no one offers any interruption. But those which bear the heavy burden of the flesh, being weighed down and oppressed by it, are unable to look upwards to the revolutions of the heaven, but being dragged downwards, have their necks forcibly pressed to the ground like so many quadrupeds.
 In reference to which fact, the lawgiver having determined to put an end to all illegal and illegitimate associations and unions, begins his denunciations in the following manner: "Man shall not come near to any one who is akin to his own flesh, to uncover his nakedness: I am the Lord." Leviticus xviii. 6. How could any one more forcibly exhort man to despise the flesh and what is akin to the flesh than in this way? And indeed he does not only exhort us to abandon such things, but he shows positively that he who is really a man will never

come of his own accord to those pleasures which are dear to and connected with the body, but will always be meditating to alienate himself from them entirely. For the saying, "man, man," not once but twice, is a sign that what is here meant is not the man composed of body and soul, but him only who is possessed of virtue. For such an one is really a true man, whom some one of the ancient philosophers having lighted a lantern at midday, went in search of, and told those who asked him that he was seeking a man. And as for the prohibition against every man coming near to any one who is akin to his own flesh, this is induced by necessary reasons. For there are some things which we should admit, such for instance as those useful things, by the employment of which we may be able to live in freedom from disease and in good health; and there are other things which should be rejected, by which, when the appetites become inflamed, they burn up all goodness in one vast conflagration.
 Let not then our appetites rush eagerly in pursuit of all the things that are pleasant to the flesh, for the pleasures are often untameable, when like dogs they fawn upon us, and all of a sudden, change and bite us, inflicting incurable wounds. So that by cleaving to frugality, which is a friend to virtue, in preference to the pleasures akin to the body, we shall defeat the numerous and infinite multitude of irreconcilable enemies. And if any occasion should seek to compel us to take more than what is moderate or sufficient, let us not yield; for the scripture saith, "He shall come near to him to uncover his nakedness."
