(36) What is the meaning of the expression, "Ye shall be as gods, knowing good and evil?" (#Ge 3:5). Whence was it that the serpent found the plural word "gods," when there is only one true God, and when this is the first time that he names him? But perhaps this arises from there having been in him a certain prescient wisdom, by which he now declared the notion of the multitude of gods which was at a future time to prevail amongst men; and, perhaps, history now relates this correctly at its first being advanced not by any rational being, nor by any creature of the higher class, but as having derived its origin from the most virulent and vile of beasts and serpents, since other similar creatures lie hid under the earth, and their lurking places are in the holes and fissures of the earth. Moreover, it is the inseparable sign of a being endowed with reason to look upon God as essentially one being, but it is the mark of a beast to imagine that there are many gods, and these too devoid of reason, and who can scarcely be said with propriety to have any existence at all. Moreover, the devil proceeds with great art, speaking by the mouth of the serpent. For not only is there in the Divinity the knowledge of good and evil, but there is also an approval of what is good and a repudiation of what is evil; but he does not speak of either of these feelings because they were useful, but only suggested the mere knowledge of the two contrary things, namely, of good and evil. In the second place, the expression, "as gods," in the plural number, is in this place not used inconsiderately, but in order to give the idea of there being both a bad and a good God. And these are of a twofold quality. Therefore it is suitable to the notion of particular gods to have a knowledge of contrary things; but the Supreme Cause is above all others.
Now the tempter's words would not have caused the tempted pair to sin had not their greed abetted the tempter. And even if the tempter had not come, the Tree with all its beauty would have caused them a struggle with their greed. In other words, they used the serpent's counsel as an excuse, for it was their own greed, which conformed with the serpent's counsel and went beyond it, that brought harm upon them.
Do you see how the devil led her captive, handicapped her reasoning and caused her to set her thoughts on goals beyond her real capabilities, in order that she might be puffed up with empty hopes and lose her hold on the advantages already accorded her?
But it is most truly said … "Pride is the beginning of all sin," for it was this sin that overthrew the devil, from whom arose the origin of sin and who, through subsequent envy, overturned the man who was standing in the righteousness from which he had fallen. For the serpent, seeking a way to enter, clearly sought the door of pride, when he declared, "You shall be as gods." That is why it is written, "Pride is the beginning of all sin," and "The beginning of the pride of man is to fall away from God."
The conclusion is that the devil would not have begun by an open and obvious sin to tempt man into doing something that God had forbidden, had not man already begun to seek satisfaction in himself and consequently to take pleasure in the words "you shall be as gods." The promise of these words, however, would much more truly have to pass if, by obedience, Adam and Eve had kept close to the ultimate and true source of their being and had not, by pride, imagined that they were themselves the source of their being.… Whoever seeks to be more than he is becomes less. Whenever he aspires to be self-sufficing, he retreats from the One who is truly sufficient for him.
[Hyperichius] also said, ‘The serpent whispered to Eve and cast her out of paradise. The man who whispers against his neighbour is like the serpent. He condemns the soul of whoever listens to him, and he does not save his own.’
