Thus, then, the milk which is perfect is perfect nourishment, and brings to that consummation which cannot cease. Wherefore also the same milk and honey were promised in the rest. Rightly, therefore, the Lord again promises milk to the righteous, that the Word may be clearly shown to be both, "the Alpha and Omega, beginning and end;" [1110] the Word being figuratively represented as milk. Something like this Homer oracularly declares against his will, when he calls righteous men milk-fed (galaktophagoi). [1111] So also may we take the Scripture: "And I, brethren, could not speak unto you as unto spiritual, but as unto carnal, even as unto babes in Christ;" [1112] so that the carnal may be understood as those recently instructed, and still babes in Christ. For he called those who had already believed on the Holy Spirit spiritual, and those newly instructed and not yet purified carnal; whom with justice he calls still carnal, as minding equally with the heathen the things of the flesh: "For whereas there is among you envy and strife, are ye not carnal, and walk as men?" [1113] "Wherefore also I have given you milk to drink," he says; meaning, I have instilled into you the knowledge which, from instruction, nourishes up to life eternal. But the expression, "I have given you to drink" (epotisa), is the symbol of perfect appropriation. For those who are full-grown are said to drink, babes to suck. "For my blood," says the Lord, "is true drink." [1114] In saying, therefore, "I have given you milk to drink," has he not indicated the knowledge of the truth, the perfect gladness in the Word, who is the milk? And what follows next, "not meat, for ye were not able," may indicate the clear revelation in the future world, like food, face to face. "For now we see as through a glass," the same apostle says, "but then face to face." [1115] Wherefore also he has added, "neither yet are ye now able, for ye are still carnal," minding the things of the flesh,--desiring, loving, feeling jealousy, wrath, envy. "For we are no more in the flesh," [1116] as some suppose. For with it [they say], having the face which is like an angel's, we shall see the promise face to face. How then, if that is truly the promise after our departure hence, say they that they know "what eye hath not known, nor hath entered into the mind of man," who have not perceived by the Spirit, but received from instruction "what ear hath not heard," [1117] or that ear alone which "was rapt up into the third heaven?" [1118] But it even then was commanded to preserve it unspoken.
But if human wisdom, as it remains to understand, is the glorying in knowledge, hear the law of Scripture: "Let not the wise man glory in his wisdom, and let not the mighty man glory in his might; but let him that glorieth glory in the Lord." [1119] But we are God-taught, and glory in the name of Christ. How then are we not to regard the apostle as attaching this sense to the milk of the babes? And if we who preside over the Churches are shepherds after the image of the good Shepherd, and you the sheep, are we not to regard the Lord as preserving consistency in the use of figurative speech, when He speaks also of the milk of the flock? And to this meaning we may secondly accommodate the expression, "I have given you milk to drink, and not given you food, for ye are not yet able," regarding the meat not as something different from the milk, but the same in substance. For the very same Word is fluid and mild as milk, or solid and compact as meat. And entertaining this view, we may regard the proclamation of the Gospel, which is universally diffused, as milk; and as meat, faith, which from instruction is compacted into a foundation, which, being more substantial than hearing, is likened to meat, and assimilates to the soul itself nourishment of this kind. Elsewhere the Lord, in the Gospel according to John, brought this out by symbols, when He said: "Eat ye my flesh, and drink my blood;" [1120] describing distinctly by metaphor the drinkable properties of faith and the promise, by means of which the Church, like a human being consisting of many members, is refreshed and grows, is welded together and compacted of both,--of faith, which is the body, and of hope, which is the soul; as also the Lord of flesh and blood. For in reality the blood of faith is hope, in which faith is held as by a vital principle. And when hope expires, it is as if blood flowed forth; and the vitality of faith is destroyed. If, then, some would oppose, saying that by milk is meant the first lessons--as it were, the first food--and that by meat is meant those spiritual cognitions to which they attain by raising themselves to knowledge, let them understand that, in saying that meat is solid food, and the flesh and blood of Jesus, they are brought by their own vainglorious wisdom to the true simplicity. For the blood is found to be an original product in man, and some have consequently ventured to call it the substance of the soul. And this blood, transmuted by a natural process of assimilation in the pregnancy of the mother, through the sympathy of parental affection, effloresces and grows old, in order that there may be no fear for the child. Blood, too, is the moister part of flesh, being a kind of liquid flesh; and milk is the sweeter and finer part of blood. For whether it be the blood supplied to the foetus, and sent through the navel of the mother, or whether it be the menses themselves shut out from their proper passage, and by a natural diffusion, bidden by the all-nourishing and creating God, proceed to the already swelling breasts, and by the heat of the spirits transmuted, [whether it be the one or the other] that is formed into food desirable for the babe, that which is changed is the blood. For of all the members, the breasts have the most sympathy with the womb. When there is parturition, the vessel by which blood was conveyed to the foetus is cut off: there is an obstruction of the flow, and the blood receives an impulse towards the breasts; and on a considerable rush taking place, they are distended, and change the blood to milk in a manner analogous to the change of blood into pus in ulceration. Or if, on the other hand, the blood from the veins in the vicinity of the breasts, which have been opened in pregnancy, is poured into the natural hollows of the breasts; and the spirit discharged from the neighbouring arteries being mixed with it, the substance of the blood, still remaining pure, it becomes white by being agitated like a wave; and by an interruption such as this is changed by frothing it, like what takes place with the sea, which at the assaults of the winds, the poets say, "spits forth briny foam." Yet still the essence is supplied by the blood.
In this way also the rivers, borne on with rushing motion, and fretted by contact with the surrounding air, murmur forth foam. The moisture in our mouth, too, is whitened by the breath. What an absurdity [1121] is it, then, not to acknowledge that the blood is converted into that very bright and white substance by the breath! The change it suffers is in quality, not in essence. You will certainly find nothing else more nourishing, or sweeter, or whiter than milk. In every respect, accordingly, it is like spiritual nourishment, which is sweet through grace, nourishing as life, bright as the day of Christ.
The blood of the Word has been also exhibited as milk. Milk being thus provided in parturition, is supplied to the infant; and the breasts, which till then looked straight towards the husband, now bend down towards the child, being taught to furnish the substance elaborated by nature in a way easily received for salutary nourishment. For the breasts are not like fountains full of milk, flowing in ready prepared; but, by effecting a change in the nutriment, form the milk in themselves, and discharge it. And the nutriment suitable and wholesome for the new-formed and new-born babe is elaborated by God, the nourisher and the Father of all that are generated and regenerated,--as manna, the celestial food of angels, flowed down from heaven on the ancient Hebrews. Even now, in fact, nurses call the first-poured drink of milk by the same name as that food--manna. Further, pregnant women, on becoming mothers, discharge milk. But the Lord Christ, the fruit of the Virgin, did not pronounce the breasts of women blessed, nor selected them to give nourishment; but when the kind and loving Father had rained down the Word, Himself became spiritual nourishment to the good. O mystic marvel! The universal Father is one, and one the universal Word; and the Holy Spirit is one and the same everywhere, and one is the only virgin mother. I love to call her the Church. This mother, when alone, had not milk, because alone she was not a woman. But she is once virgin and mother--pure as a virgin, loving as a mother. And calling her children to her, she nurses them with holy milk, viz., with the Word for childhood. Therefore she had not milk; for the milk was this child fair and comely, the body of Christ, which nourishes by the Word the young brood, which the Lord Himself brought forth in throes of the flesh, which the Lord Himself swathed in His precious blood. O amazing birth! O holy swaddling bands! The Word is all to the child, both father and mother and tutor and nurse. "Eat ye my flesh," He says, "and drink my blood." [1122] Such is the suitable food which the Lord ministers, and He offers His flesh and pours forth His blood, and nothing is wanting for the children's growth. O amazing mystery! We are enjoined to cast off the old and carnal corruption, as also the old nutriment, receiving in exchange another new regimen, that of Christ, receiving Him if we can, to hide Him within; and that, enshrining the Saviour in our souls, we may correct the affections of our flesh.
But you are not inclined to understand it thus, but perchance more generally. Hear it also in the following way. The flesh figuratively represents to us the Holy Spirit; for the flesh was created by Him. The blood points out to us the Word, for as rich blood the Word has been infused into life; and the union of both is the Lord, the food of the babes--the Lord who is Spirit and Word. The food--that is, the Lord Jesus--that is, the Word of God, the Spirit made flesh, the heavenly flesh sanctified. The nutriment is the milk of the Father, by which alone we infants are nourished. The Word Himself, then, the beloved One, and our nourisher, hath shed His own blood for us, to save humanity; and by Him, we, believing on God, flee to the Word, "the care-soothing breast" of the Father. And He alone, as is befitting, supplies us children with the milk of love, and those only are truly blessed who suck this breast. Wherefore also Peter says: "Laying therefore aside all malice, and all guile, and hypocrisy, and envy, and evil speaking, as new-born babes, desire the milk of the word, that ye may grow by it to salvation; if ye have tasted that the Lord is Christ." [1123] And were one to concede to them that the meat was something different from the milk, then how shall they avoid being transfixed on their own spit, through want of consideration of nature? [1124] For in winter, when the air is condensed, and prevents the escape of the heat enclosed within, the food, transmuted and digested and changed into blood, passes into the veins, and these, in the absence of exhalation, are greatly distended, and exhibit strong pulsations; consequently also nurses are then fullest of milk. And we have shown a little above, that on pregnancy blood passes into milk by a change which does not affect its substance, just as in old people yellow hair changes to grey. But again in summer, the body, having its pores more open, affords greater facility for diaphoretic action in the case of the food, and the milk is least abundant, since neither is the blood full, nor is the whole nutriment retained. If, then, the digestion of the food results in the production of blood, and the blood becomes milk, then blood is a preparation for milk, as blood is for a human beings, and the grape for the vine. With milk, then, the Lord's nutriment, we are nursed directly we are born; and as soon as we are regenerated, we are honoured by receiving the good news of the hope of rest, even the Jerusalem above, in which it is written that milk and honey fall in showers, receiving through what is material the pledge of the sacred food. "For meats are done away with," [1125] as the apostle himself says; but this nourishment on milk leads to the heavens, rearing up citizens of heaven, and members of the angelic choirs. And since the Word is the gushing fountain of life, and has been called a river of olive oil, Paul, using appropriate figurative language, and calling Him milk, adds: "I have given you to drink;" [1126] for we drink in the word, the nutriment of the truth. In truth, also liquid food is called drink; and the same thing may somehow be both meat and drink, according to the different aspects in which it is considered, just as cheese is the solidification of milk or milk solidified; for I am not concerned here to make a nice selection of an expression, only to say that one substance supplies both articles of food. Besides, for children at the breast, milk alone suffices; it serves both for meat and drink. "I," says the Lord, "have meat to eat that ye know not of. My meat is to do the will of Him that sent Me." [1127] You see another kind of food which, similarly with milk, represents figuratively the will of God. Besides, also, the completion of His own passion He called catachrestically "a cup," [1128] when He alone had to drink and drain it. Thus to Christ the fulfilling of His Father's will was food; and to us infants, who drink the milk of the word of the heavens, Christ Himself is food. Hence seeking is called sucking; for to those babes that seek the Word, the Father's breasts of love supply milk.
