Genesis 3:7

7.And the eyes of them both were opened. It was necessary that the eyes of Eve should be veiled till her husband also was deceived; but now both, being alike bound by the chain of an unhappy consent, begin to be sensible of their wretchedness although they are not yet affected with a deep knowledge of their fault. They are ashamed of their nakedness, yet, though convinced, they do not humble themselves before God, nor fear his judgements as they ought; they even do not cease to resort to evasions. Some progress, however, is made; for whereas recently they would, like giants, assault heaven by storm; now, confounded with a sense of their own ignominy, they flee to hiding-places. And truly this opening of the eyes in our first parents to discern their baseness, clearly proves them to have been condemned by their own judgment. They are not yet summoned to the tribunal of God; there is none who accuses them; is not then the sense of shame, which rises spontaneously, a sure token of guilt? The eloquence, therefore, of the whole world will avail nothing to deliver those from condemnation, whose own conscience has become the judge to compel them to confess their fault. It rather becomes us all to open our eyes, that, being confounded at our own disgrace, we may give to God the glory which is his due. God created man flexible; and not only permitted, but willed that he should be tempted. For he both adapted the tongue of the serpent beyond the ordinary use of nature, to the devil’s purpose, just as if any one should furnish another with a sword and armor; and then, though the unhappy event was foreknown by him, he did not apply the remedy, which he had the power to do. On the other hand, when we come to speak of man, he will be found to have sinned voluntarily, and to have departed from God, his Maker, by a movement of the mind not less free than perverse. Nor ought we to call that a light fault, which, refusing credit to the word of God, exalted itself against him by impious and sacrilegious emulation, which would not be subject to his authority, and which, finally, both proudly and perfidiously revolted from him. Therefore, whatever sin and fault there is in the fall of our first parents remains with themselves; but there is sufficient reason why the eternal counsel of God preceded it, though that reason is concealed from us. We see, indeed, some good fruit daily springing from a ruin so dreadful, inasmuch as God instructs us in humility by our miseries and then more clearly illustrates his own goodness; for his grace is more abundantly poured forth, through Christ, upon the world, than it was imparted to Adam in the beginning. Now, if the reason why this is so lies beyond our reach, it is not wonderful that the secret counsel of God should be to us like a labyrinth. (175)

And they sewed fig - leaves together. What I lately said, that they had not been brought either by true shame or by serious fear to repentance, is now more manifest. They sew together for themselves girdles of leaves. (176) For what end? That they may keep God at a distance, as by an invincible barrier! Their sense of evil, therefore, was only confused, and combined with dulness, as is wont to be the case in unquiet sleep. There is none of us who does not smile at their folly, since, certainly, it was ridiculous to place such a covering before the eyes of God. In the meanwhile, we are all infected with the same disease; for, indeed, we tremble, and are covered with shame at the first compunctions of conscience; but self-indulgence soon steals in, and induces us to resort to vain trifles, as if it were an easy thing to delude God. Therefore unless conscience be more closely pressed there is no shadow of excuse too faint and fleeting to obtain our acquiescence; and even if there be no pretext whatever, we still make pleasures for ourselves, and, by an oblivion of three days’ duration, we imagine that we are well covered. (177) In short, the cold and faint (178) knowledge of sin, which is inherent in the minds of men, is here described by Moses, in order that they may be rendered inexcusable. (179) Then (as we have already said) Adam and his wife were yet ignorant of their own vileness, since with a covering so light they attempted to hide themselves from the presence of God.
