1 Now, that He who at the beginning created man, did promise him a second birth after his dissolution into earth, Esaias thus declares: “The dead shall rise again, and they who are in the tombs shall arise, and they who are in the earth shall rejoice. For the dew which is from You is health to them.” And again: “I will comfort you, and you shall be comforted in Jerusalem: and you shall see, and your heart shall rejoice, and your bones shall flourish as the grass; and the hand of the Lord shall be known to those who worship Him.” And Ezekiel speaks as follows: “And the hand of the Lord came upon me, and the Lord led me forth in the Spirit, and set me down in the midst of the plain, and this place was full of bones. And He caused me to pass by them round about: and, behold, there were many upon the surface of the plain very dry. And He said unto me, Son of man, can these bones live? And I said, Lord, You who has made them knows. And He said unto me, Prophesy upon these bones, and you shall say to them, You dry bones, hear the word of the Lord. Thus says the Lord to these bones, Behold, I will cause the spirit of life to come upon you, and I will lay sinews upon you, and bring up flesh again upon you, and I will stretch skin upon you, and will put my Spirit into you, and you shall live; and you shall know that I am the Lord. And I prophesied as the Lord had commanded me. And it came to pass, when I was prophesying, that, behold, an earthquake, and the bones were drawn together, each one to its own articulation: and I beheld, and, lo, the sinews and flesh were produced upon them, and the skins rose upon them round about, but there was no breath in them. And He said unto me, Prophesy to the breath, son of man, and say to the breath, These things says the Lord, Come from the four winds (spiritibus), and breathe upon these dead, that they may live. So I prophesied as the Lord had commanded me, and the breath entered into them; and they did live, and stood upon their feet, an exceeding great gathering.” And again he says, “Thus says the Lord, Behold, I will set your graves open, and cause you to come out of your graves, and bring you into the land of Israel; and you shall know that I am the Lord, when I shall open your sepulchres, that I may bring my people again out of the sepulchres: and I will put my Spirit into you, and you shall live; and I will place you in your land, and you shall know that I am the Lord. I have said, and I will do, says the Lord.” As we at once perceive that the Creator (Demiurgo) is in this passage represented as vivifying our dead bodies, and promising resurrection to them, and resuscitation from their sepulchres and tombs, conferring upon them immortality also (He says, “For as the tree of life, so shall their days be”), He is shown to be the only God who accomplishes these things, and as Himself the good Father, benevolently conferring life upon those who have not life from themselves.
2. And for this reason did the Lord most plainly manifest Himself and the Father to His disciples, lest, forsooth, they might seek after another God besides Him who formed man, and who gave him the breath of life; and that men might not rise to such a pitch of madness as to feign another Father above the Creator. And thus also He healed by a word all the others who were in a weakly condition because of sin; to whom also He said, “Behold, you are made whole, sin no more, lest a worse thing come upon you:” pointing out by this, that, because of the sin of disobedience, infirmities have come upon men. To that man, however, who had been blind from his birth, He gave sight, not by means of a word, but by an outward action; doing this not without a purpose, or because it so happened, but that He might show forth the hand of God, that which at the beginning had moulded man. And therefore, when His disciples asked Him for what cause the man had been born blind, whether for his own or his parents' fault, He replied, “Neither has this man sinned, nor his parents, but that the works of God should be made manifest in him.” Now the work of God is the fashioning of man. For, as the Scripture says, He made [man] by a kind of process: “And the Lord took clay from the earth, and formed man.” Wherefore also the Lord spat on the ground and made clay, and smeared it upon the eyes, pointing out the original fashioning [of man], how it was effected, and manifesting the hand of God to those who can understand by what [hand] man was formed out of the dust. For that which the artificer, the Word, had omitted to form in the womb, [viz., the blind man's eyes], He then supplied in public, that the works of God might be manifested in him, in order that we might not be seeking out another hand by which man was fashioned, nor another Father; knowing that this hand of God which formed us at the beginning, and which does form us in the womb, has in the last times sought us out who were lost, winning back His own, and taking up the lost sheep upon His shoulders, and with joy restoring it to the fold of life.
3. Now, that the Word of God forms us in the womb, He says to Jeremiah, “Before I formed you in the womb, I knew you; and before you went forth from the belly, I sanctified you, and appointed you a prophet among the nations.” And Paul, too, says in like manner, “But when it pleased God, who separated me from my mother's womb, that I might declare Him among the nations.” As, therefore, we are by the Word formed in the womb, this very same Word formed the visual power in him who had been blind from his birth; showing openly who it is that fashions us in secret, since the Word Himself had been made manifest to men: and declaring the original formation of Adam, and the manner in which he was created, and by what hand he was fashioned, indicating the whole from a part. For the Lord who formed the visual powers is He who made the whole man, carrying out the will of the Father. And inasmuch as man, with respect to that formation which, was after Adam, having fallen into transgression, needed the laver of regeneration, [the Lord] said to him [upon whom He had conferred sight], after He had smeared his eyes with the clay, “Go to Siloam, and wash;” thus restoring to him both [his perfect] confirmation, and that regeneration which takes place by means of the laver. And for this reason when he was washed he came seeing, that he might both know Him who had fashioned him, and that man might learn [to know] Him who has conferred upon him life.
