Augustine of Hippo : For as a snake does not creep on with open steps, but advances by the very minutest efforts of its several scales; so the slippery motion of falling away [from what is good] takes possession of the negligent only gradually, and beginning from a perverse desire for the likeness of God, arrives in the end at the likeness of beasts. Hence it is that being naked of their first garment, they earned by mortality coats of skins. For the true honor of man is the image and likeness of God, which is not preserved except it be in relation to Him by whom it is impressed. The less therefore that one loves what is one's own, the more one cleaves to God. But through the desire of making trial of his own power, man by his own bidding falls down to himself as to a sort of intermediate grade. And so, while he wishes to be as God is, that is, under no one, he is thrust on, even from his own middle grade, by way of punishment, to that which is lowest, that is, to those things in which beasts delight: and thus, while his honor is the likeness of God, but his dishonor is the likeness of the beast, "Man being in honor abideth not: he is compared to the beasts that are foolish, and is made like to them." — On the Trinity 12.11.16 Bede : And the Lord God made for Adam and his wife tunics of skins, and clothed them. And this was done for the sake of significance, yet it was indeed done. For by this kind of garment, the Lord indicates that they had already been made mortal; for skins, which are not stripped from animals unless they are dead, contain the figure of death. Thus, when man sought to be God against the commandment, not by legitimate imitation, but by illicit pride, he was cast down to the mortality of beasts. And indeed, they had made for themselves girdles of fig leaves, to cover their shame: but God made for them tunics of skins, to cover their whole body: because they, having lost the glory of innocence through transgression, provided for themselves the covering of excuse, by which they transferred their guilt to the Creator: and the Creator himself, by the sentence of a just judgment, punished them with the penalty of mortality in both soul and flesh, having taken away the state of immutable life. Moreover, the Gospel parable narrates that the merciful father, among other gifts, ordered the first robe to be brought and put on his prodigal son returning to him through repentance, mystically signifying that the elect are to receive the habit of immortality, which they lost in Adam at the beginning of the world, at the end of the world in Christ, and indeed with greater grace. For Adam was made immortal in such a way that he could not die, if he kept the commandment: but the children of the resurrection will be so immortal that they can neither die ever, nor be affected by the fear of death. Regarding the reception of this robe, the Apostle says: For this corruptible must put on incorruption, and this mortal must put on immortality (I Cor. XV, 53): where "put on" signifies the removal of the nakedness, which Adam and Eve recognized and blushed for after sin. — Commentary on Genesis (Hexaemeron) Ephrem the Syrian : Having spoken of the punishment which the tempter and those tempted received, Scripture describes how "the Lord made garments of skin for Adam and Eve, and clothed them. " [ Gen. 3:21 ] Whether these garments were from the skins of animals, or whether they were specially created, like the thorn bushes and thistles which were created after the other works of creation had been completed, seeing that it is said that "the Lord made... and clothed them," it seems likely that when their hands were laid upon their leaves they found themselves clothed with garments made of skin. Or were, perhaps, some animals killed before them, so that they could nourish themselves with their flesh, cover up their nakedness with their skins, and in their deaths see the death of their own bodies? Ephrem the Syrian : Were these garments from the skins of animals? Or were they created like the thistles and thorns that were created after the other works of creation had been completed? Because it was said that the "Lord made … and clothed them," it seems most likely that when their hands were placed over their leaves they found themselves clothed in garments of skin. Why would beasts have been killed in their presence? Perhaps this happened so that by the animal's flesh Adam and Eve might nourish their own bodies and that with the skins they might cover their nakedness, but also that by the death of the animals Adam and Eve might see the death of their own bodies. — COMMENTARY ON Genesis 2.33.1 Gregory of Nyssa : Just so our nature, becoming passional, had to encounter all the necessary results of a life of passion: but when it shall have started back to that state of passionless blessedness, it will no longer encounter the inevitable results of evil tendencies. Seeing, then, that all the infusions of the life of the brute into our nature were not in us before our humanity descended through the touch of evil into passions, most certainly, when we abandon those passions, we shall abandon all their visible results. No one, therefore, will be justified in seeking in that other life for the consequences in us of any passion. Just as if a man, who, clad in a ragged tunic, has divested himself of the garb, feels no more its disgrace upon him, so we too, when we have cast off that dead unsightly tunic made from the skins of brutes and put upon us (for I take the "coats of skins" to mean that conformation belonging to a brute nature with which we were clothed when we became familiar with passionate indulgence), shall, along with the casting off of that tunic, fling from us all the belongings that were round us of that skin of a brute; and such accretions are sexual intercourse, conception, parturition, impurities, suckling, feeding, evacuation, gradual growth to full size, prime of life, old age, disease, and death. If that skin is no longer round us, how can its resulting consequences be left behind within us? — ON THE SOUL AND THE RESURRECTION John Chrysostom : In other words, take the case of a kindly father with a son of his own who was brought up with every care, who enjoyed every indulgence, had the run of a fine house, was clad in a silken tunic, and had free access to his father's substance and wealth; later, when he saw him tumble headlong from this great indulgence into an abyss of wickedness, he stripped him of all those assets, subjected him to his own authority and, divesting him of his clothes, clad him in a lowly garment usually worn by slaves lest he be completely naked and indecent. Well, in just the same way the loving God, when they rendered themselves unworthy of that gleaming and resplendent vesture in which they were adorned and which ensured they were prepared against bodily needs, stripped them of all that glory and the enjoyment they were partakers of before suffering that terrible fall. He showed them great pity and had mercy on their fall: seeing them covered in confusion and ignorant of what to do to avoid being naked and feeling ashamed, he makes garments of skin for them and clothes them in them. What I mean is that the machinations of the devil are quite different: when he finds people ready to do his will, he proves their undoing through some slight enjoyment, then drags them down to the very depths of wickedness and covers them in utter shame and degradation, leaving them prostrate, a piteous spectacle for all to see whereas the Guardian of our souls, seeing them in utter helplessness, doesn't allow himself to ignore their condition but devises a covering for them, while indicating to them through the frugality of the garment the sort of garments they have caused themselves to deserve. "The Lord God made garments of skin for Adam and his wife, and clad them in them." See the extent of the considerateness of Sacred Scripture. Still, what I've often said I say again now: let us understand everything in a sense befitting God. Let us understand "made" in the sense of "gave directions for" : he ordered that they be clad in garments of skin as a constant reminder of their disobedience. Let the affluent pay heed, those who pamper themselves with cloth from the silkworm and are clad in silk, and let them learn how at the beginning from the outset the loving Lord instructed the human race: when the firstformed man became liable to the punishment of death through the Fall and the Lord had to clothe him in a garment to hide his shame, he made them garments of skin, to teach us to shun the soft and dissolute life, and not to pine for one that is lazy and characterized by inactivity, but rather strive for an austere life. Perhaps, however, the wealthy will react badly to our words and will say, What reason is there in that? do you bid us wear garments of skin? No, I'm not saying that; after all, not even Adam and Eve wore those garments all the time, the loving Lord always adding further kindnesses to his previous ones, you see. I mean, when he rendered them liable to bodily necessities for the future, stripping them of the angelic way of life and its freedom from suffering, he later arranged for clothes for human beings out of sheep's fleece for no other reason than that they should have covering and that this rational creature should not live his life in nakedness and ugliness just like brute beasts. Accordingly, let the wearing of clothes be a constant reminder to us of the loss of advantages and instruction about the punishment which the race of human beings received on account of disobedience. Accordingly, let those people who make use of such paraphernalia that they are no longer familiar with garments of sheep's wool, but are clad in silk and have been carried to such extremes that they even drape gold with covering, the female sex particularly demonstrating this kind of luxury let them, I say, tell us: Why do you dress up the body with these things and delight in clothing of that kind, not understanding that this covering was devised as severe punishment for the Fall? I mean, why do you not heed Paul's words, "We will be content to have food and clothing." Do you see that it is necessary to be concerned with one thing only, that the body not be naked, and to have an eye only to this, that no further worry be had about variety of dress? Origen of Alexandria : It is said that God made those miserable garments with which the first man was clothed after he had sinned. "For God made skin tunics and clothed Adam and his wife." Therefore, those were tunics of skin taken from animals. For with such as these, it was necessary for the sinner to be dressed. It says, "with skin tunics," which are a symbol of the mortality that he received because of his skin and of his frailty that came from the corruption of the flesh. But if you have been already washed from these and purified through the law of God, then Moses will dress you with a garment of incorruptibility so that "your shame may never appear"and "that what is mortal may be swallowed up by life." — HOMILIES ON Leviticus 6.2.7
