Disclosure of the Monstrous Tenets of the Manichæans
49 Is your reason for thinking the bodies of trees better than our bodies, that flesh is nourished by trees and not trees by flesh. You forget the obvious fact that plants, when manured with dung, become richer and more fertile and crops heavier, though you think it your gravest charge against flesh that it is the abode of dung. This then gives nourishment to things you consider clean, though it is, according to you, the most unclean part of what you consider unclean. But if you dislike flesh because it springs from sexual intercourse, you should be pleased with the flesh of worms, which are bred in such numbers, and of such a size, in fruits, in wood, and in the earth itself, without any sexual intercourse. But there is some insincerity in this. For if you were displeased with flesh because it is formed from the cohabitation of father and mother, you would not say that those princes of darkness were born from the fruits of their own trees; for no doubt you think worse of these princes than of flesh, which you refuse to eat.
50. Your idea that all the souls of animals come from the food of their parents, from which confinement you pretend to liberate the divine substance which is held bound in your viands, is quite inconsistent with your abstinence from flesh, and makes it a pressing duty for you to eat animal food. For if souls are bound in the body by those who eat animal food, why do you not secure their liberation by being beforehand in eating the food? You reply, it is not from the animal food that the good part comes which those people bring into bondage, but from the vegetables which they take with their meat. What will you say then of the souls of lions, who feed only on flesh? They drink, is the reply, and so the soul is drawn in from the water and confined in flesh. But what of birds without number? What of eagles, which eat only flesh, and need no drink? Here you are at a loss, and can find no answer. For if the soul comes from food, and there are animals which neither drink anything nor have any food but flesh, and yet bring forth young, there must be some soul in flesh; and you are bound to try your plan of purifying it by eating the flesh. Or will you say that a pig has a soul of light, because it eats vegetables, and drinks water; and that the eagle, because it eats only flesh, has a soul of darkness, though it is so fond of the sun?
51. What a confusion of ideas! What amazing fatuity! All this you would have escaped, if you had rejected idle fictions, and had followed what truth sanctions in abstinence from food, which would have taught you that sumptuous eating is to be avoided, not to escape pollution, as there is nothing of the kind, but to subdue the sensual appetite. For should any one, from inattention to the nature of things, and the properties of the soul and body, allow that the soul is polluted by animal food, you will admit that it is much much more defiled by sensuality. Is it reasonable, then, or rather, is it not most unreasonable, to expel from the number of the elect a man who, perhaps for his health's sake, takes some animal food without sensual appetite; while, if a man eagerly devours peppered truffles, you can only reprove him for excess, but cannot condemn him as abusing your symbol? So one who has been induced, not by sensuality, but for health, to eat part of a fowl, cannot remain among your elect; though one may remain who has yielded voluntarily to an excessive appetite for comfits and cakes without animal matter. You retain the man plunged in the defilements of sensuality, and dismiss the man polluted, as you think, by the mere food; though you allow that the defilement of sensuality is far greater than that of meat. You keep hold of one who gloats with delight over highly-seasoned vegetables, unable to keep possession of himself; while you shut out one who, to satisfy hunger, takes whatever comes, if suitable for nourishment, ready either to use the food, or to let it go. Admirable customs! Excellent morals! Notable temperance!
52. Again, the notion that it is unlawful for any one but the elect to touch as food what is brought to your meals for what you call purification, leads to shameful and sometimes to criminal practices. For sometimes so much is brought that it cannot easily be eaten up by a few; and as it is considered sacrilege to give what is left to others, or, at least, to throw it away, you are obliged to eat to excess, from the desire to purify, as you call it, all that is given. Then, when you are full almost to bursting, you cruelly use force in making the boys of your sect eat the rest. So it was charged against some one at Rome that he killed some poor children, by compelling them to eat for this superstitious reason. This I should not believe, did I not know how sinful you consider it to give this food to those who are not elect, or, at any rate, to throw it away. So the only way is to eat it; and this leads every day to gluttony, and may sometimes lead to murder.
53. For the same reason you forbid giving bread to beggars. By way of showing compassion, or rather of avoiding reproach, you advise to give money. The cruelty of this is equalled by its stupidity. For suppose a place where food cannot be purchased: the beggar will die of starvation, while you, in your wisdom and benevolence, have more mercy on a cucumber than on a human being! This is in truth (for how could it be better designated) pretended compassion, and real cruelty. Then observe the stupidity. What if the beggar buys bread for himself with the money you give him? Will the divine part, as you call it, not suffer the same in him when he buys the food as it would have suffered if he had taken it as a gift from you? So this sinful beggar plunges in corruption part of God eager to escape, and is aided in this crime by your money! But you in your great sagacity think it enough that you do not give to one about to commit murder a man to kill, though you knowingly give him money to procure somebody to be killed. Can any madness go beyond this? The result is, that either the man dies if he cannot get food for his money, or the food itself dies if he gets it. The one is true murder; the other what you call murder: though in both cases you incur the guilt of real murder. Again, there is the greatest folly and absurdity in allowing your followers to eat animal food, while you forbid them to kill animals. If this food does not defile, take it yourselves. If it defiles, what can be more unreasonable than to think it more sinful to separate the soul of a pig from its body than to defile the soul of a man with the pig's flesh.
