And that the blood is the Word, is testified by the blood of Abel, the righteous interceding with God. For the blood would never have uttered a voice, had it not been regarded as the Word: for the righteous man of old is the type of the new righteous one; and the blood of old that interceded, intercedes in the place of the new blood. And the blood that is the Word cries to God, since it intimated that the Word was to suffer. Further, this flesh, and the blood in it, are by a mutual sympathy moistened and increased by the milk. And the process of formation of the seed in conception ensues when it has mingled with the pure residue of the menses, which remains. For the force that is in the seed coagulating the substances of the blood, as the rennet curdles milk, effects the essential part of the formative process. For a suitable blending conduces to fruitfulness; but extremes are adverse, and tend to sterility. For when the earth itself is flooded by excessive rain, the seed is swept away, while in consequence of scarcity it is dried up; but when the sap is viscous, it retains the seed, and makes it germinate. Some also hold the hypothesis, that the seed of an animal is in substance the foam of the blood, which being by the natural heat of the male agitated and shaken out, in copulation is turned into foam, and deposited in the seminal veins. For Diogenes Apollionates will have it, that hence is derived the word _aphrodisia_. From all this it is therefore evident, that the essential principle of the human body is blood. The contents of the stomach, too, at first are milky, a coagulation of fluid; then the same coagulated substance is changed into blood; but when it is formed into a compact consistency in the womb, by the natural and warm spirit by which the embryo is fashioned, it becomes a living creature. Further also, the child after birth is nourished by the same blood. For the flow of milk is the product of the blood; and the source of nourishment is the milk; by which a woman is shown to have brought forth a child, and to be truly a mother, by which also she receives a potent charm of affection. Wherefore the Holy Spirit in the apostle, using the voice of the Lord, says mystically, “I have given you milk to drink.”[249] For if we have been regenerated unto Christ, He who has regenerated us nourishes us with His own milk, the Word; for it is proper that what has procreated should forthwith supply nourishment to that which has been procreated. And as the regeneration was conformably spiritual, so also was the nutriment of man spiritual. In all respects, therefore, and in all things, we are brought into union with Christ, into relationship through His blood, by which we are redeemed; and into sympathy, in consequence of the nourishment which flows from the Word; and into immortality, through His guidance: “Among men the bringing up of children Often produces stronger impulses to love than the procreating of them.”
