Early Christian Beliefs About the Tree of Knowledge and the Fall
Early Christian writers mostly taught that the tree of knowledge was good, but disobedience brought the fall. Theophilus, Irenaeus, Clement of Alexandria, and other early writers tie the sin to the serpent’s lie and Adam and Eve’s choice to eat. Genesis 2–3 is the main Bible text, and many writers read it plainly while a few add symbolic meaning. The result was shame, death, and exile from paradise.

What did early Christians believe about the Tree of Knowledge and the Fall?
Early Christian writers usually taught that the tree of knowledge was part of God’s good creation, and that the fall came through disobedience, the serpent’s deception, and Adam and Eve’s choice to eat what God forbade. Theophilus of Antioch, Mathetes in the Epistle to Diognetus, Irenaeus, Clement of Alexandria, and others repeat the same basic reading from Genesis. Several writers also say the tree itself was not evil;
the sin was disobedience, and the result was death, shame, and exile from paradise. The evidence is broad across the 1st to 3rd centuries, but some details are mixed because a few authors use the tree more symbolically or focus on later moral lessons rather than the first sin itself. Many more early Christian quotations, Bible passages, and source links are gathered below so you can study the evidence for yourself.
Key Takeaways

Theophilus of Antioch, To Autolycus Direct teaching
The tree of knowledge itself was good, and its fruit was good. For it was not the tree, as some think, but disobedience, that had death in it. For there was nothing in the fruit except knowledge, and knowledge is good when a person uses it wisely. But Adam, since he was still like an infant in age, was not yet able to receive knowledge in a proper way. Even now, when a child is born, he is not able to eat bread at once. He is first fed with milk, and then, as he grows older, he moves on to solid food. It would have been the same with Adam. God did not command him not to eat from the tree of knowledge because He was unwilling to let him have it, as some suppose. Rather, He also wanted to test him, to see whether he would submit to His commandment. At the same time, He wanted man, since he was still like an infant, to remain simple and sincere for a while longer. For this is holy, not only with God but also among men: that children should obey their parents with simplicity and without deceit. But if it is right for children to be subject to their parents, how much more should they be subject to the God and Father of all things? Besides, it is not fitting for children in infancy to be

Mathetes, Epistle to Diognetus Direct teaching
...hose who rightly love Him. You are made to be a paradise of delight, presenting within yourselves a tree bearing all kinds of produce and flourishing well, adorned with various fruits. For in this place, the tree of knowledge and the tree of life have been planted; but it is not the tree of knowledge that destroys—it is disobedience that is destructive. Furthermore, the words written about how God from the beginning planted the tree of life in the midst of paradise are not without significance, revealing through knowledge the way to life. When those who were first formed did not use this knowledge properly, they were stripped naked through the fraud of the Serpent. For neither can life exist without knowledge, nor is knowledge secure without life. Therefore, both were planted close together. The Apostle, understanding the significance of this connection and criticizing that knowledge which, without true doctrine, is allowed to influence life, declares, “Knowledge puffs up, but love builds up.” For anyone who thinks they know anything without true knowledge, and such knowledge that is supported by life, knows nothing but is deceived by the Serpent, as they do not love life. But w

Clement of Alexandria, The Stromata (Miscellanies) Background
...ough it commandments exist. Through it the law exists. Through it the Gospel exists. Through it the knowledge of God exists. "And all flesh is grass, and all its glory is like the flower of grass; and the grass dries up, and the flower falls, but the word of the Lord remains," and it anointed the soul and united it to the spirit. But how could the divine arrangement in our Church have been brought to its end without a body, when even He Himself, who is the head of the Church, passed His life in flesh that was without form and without outward beauty, so that He might teach us to look to the nature of the divine cause, which is without form and without body? For, says the proverb, "The tree of life is in good desire," Proverbs 13:12, teaching good and pure desires, which are in the living Lord. Now they want to say that a husband's intercourse with his wife in marriage, which is called knowledge, is sin. For they think it is indicated by the eating of the tree of good and evil, Genesis 3:5, through the meaning of this expression, "He knew," Genesis 4:1, which marks the transgression of the commandment. But if this is so, then the knowledge of the truth also is an eating of the tre
Did early Christians connect the fall with knowledge, shame, and being driven out of paradise?
These sources connect the fall with the first humans gaining knowledge of good and evil, realizing their nakedness, and being driven from paradise. Some also describe the event as a loss of life or immortality after the command was broken.

...whom they also claim to be angels. Their mother (Sophia) cleverly devised a plan to deceive Eve and Adam, through the serpent, to break Ialdabaoth's command. Eve listened to this as if it came from a son of God, and believed it easily. She also persuaded Adam to eat from the tree about which God had said they should not eat. They then claim that by eating, they gained the knowledge of the power above all and left those who created them. When Prunicus saw that the powers were thwarted by their own creation, she rejoiced greatly and exclaimed again that since the father was incorruptible, he (Ialdabaoth), who previously called himself the father, was a liar; and that, while Anthropos and the first woman (the Spirit) existed before, this one (Eve) sinned by committing adultery.

...w had said, You shall not covet," Romans 7:7. For when our first parents heard, "Of the tree of the knowledge of good and evil, you shall not eat of it; for in the day you eat of it you shall surely die," Genesis 2:17, then they conceived lust and took it in. Therefore it was said, "I had not known lust, except the law had said, You shall not covet." Nor would they have desired to eat, unless it had been said, "You shall not eat of it." For it was from there that sin took an occasion to deceive me. For when the law was given, the devil had power to work lust in me; for "without the law, sin was dead," Romans 7:8, which means that when the law had not been given, sin could not be committed. But "I was alive and blameless before the law," having no commandment by which it was necessary to live. But when the commandment came, sin revived, and I died. "And the commandment, which was ordained to life, I found to be to death," Romans 7:9-10. For after God had given the law, and had commanded me what I ought to do and what I ought not to do, the devil worked lust in me. For the promise of God given to me was for life and incorruption, so that by obeying it I might have ever-flourishing

Irenaeus, Fragments from the Lost Writings of Irenæus Supporting witness
... resisted the serpent for a time and ate from the tree only after being cunningly deceived; whereas Adam, without any resistance, ate the fruit given by the woman, showing extreme weakness and lack of resolve. The woman, having been defeated by a demon, is deserving of pardon; but Adam deserves none, for he was overcome by a woman—the same man who had directly received God's command. The woman, having heard the command from Adam, ignored it, either because she thought it unworthy of God or had doubts, perhaps even thinking the command came from Adam himself. The serpent found her working alone and was thus able to converse with her. Seeing her either eating or not eating from the trees, he offered her the fruit of the forbidden tree. If he saw her eating, it shows that she had a mortal, corruptible body, for “everything going in at the mouth is cast out.” If corruptible, she was mortal, so there was no curse, nor was there condemnation when God told the man, “For dust you are, and to dust you shall return,” which has always been the natural order. If the serpent saw her not eating, how did he persuade her to eat who had never eaten? Who informed this cursed, man-deceiving serpen

However, my point here is not to focus on this aspect, but to prove to you that the Holy Spirit reproaches people because they were made like God, free from suffering and death, as long as they followed His commandments, and were considered worthy of being called His sons, but they, like Adam and Eve, bring death upon themselves; you may interpret the Psalm as you prefer, yet it demonstrates that all people are considered worthy of becoming “gods,” and having the power to become sons of the Highest; and will each be judged and condemned like Adam and Eve. Now I have shown extensively that Christ is called God.

And the serpent said to the woman, “Why has God said, ‘You shall not eat from every tree of the garden’?” And the woman said to the serpent, “We may eat from every tree of the garden, but about the fruit of the tree that is in the middle of the garden, God has said, ‘You shall not eat it, and you shall not touch it, lest you die.’” And the serpent said to the woman, “You will not surely die. For God knows that on the day you eat of it, your eyes will be opened, and you will be like gods, knowing good and evil.” And the woman saw that the tree was good for food, pleasing to the eyes, and desirable for making one wise. So she took its fruit and ate. She also gave some to her husband, who was with her, and they ate. Then the eyes of both of them were opened, and they knew that they were naked. So they sewed fig leaves together and made coverings for themselves. And they heard the voice of the Lord God walking in the garden in the cool of the day, and Adam and his wife hid themselves from the presence of the Lord God among the trees of the garden.

Theophilus of Antioch, To Autolycus Supporting witness
After Adam was driven out of Paradise, while he was in that condition, he knew Eve his wife. God had formed her for him as a wife out of his rib. God did this, not because He was unable to make his wife separately, but because God knew beforehand that man would call on many gods. Since He knew this in advance, and knew that through the serpent error would bring in many gods that did not exist—for there is only one God, and even then error was trying to spread the idea of many gods, saying, "You shall be as gods"—therefore, so that it would not be thought that one God made the man and another made the woman, He made them both. And God made the woman together with the man, not only to show the mystery of God's sole rule, but also so that their love for each other might be greater. Therefore Adam said to Eve, "This is now bone of my bones, and flesh of my flesh." Besides this, he also prophesied when he said, "For this cause shall a man leave his father and his mother, and shall cleave to his wife; and they two shall be one flesh." This also is fulfilled in us. For who is there that marries lawfully and does not set aside mother and father, and his whole family connection, and all his

...eived by the devil's lies and craftiness, and after the devil had also entered into the body of the serpent, which was the most sagacious of all the beasts, then from that time the devil was called a liar together with his father. Then also the curse came to rest not only on himself, but also on his father. "Accordingly, when the serpent received him, and indeed admitted him completely into its own being, it was, as it were, made pregnant, for it carried the burden of the devil's vast wickedness. It was like one with child, and under the strain of labor, as it tried to cast out the agitations of his malignant suggestions. For the serpent, grudging the glory of the first man, made its way into paradise. And carrying these pains of labor within itself, it began to produce lying speeches, and to bring forth death for the men who had been formed by God and had received the gift of life. "The devil, however, was not able to show himself fully through the serpent. But he kept his perfection for a time, so that he might show it through Cain, by whom he was fully brought forth. And so through the serpent, on the one hand, he showed his hypocrisies and deceits to Eve; while through Cain,

...virtue. These are ready to be opened to him who follows after virtuous pursuits. The subject of the tree of life will be explained more appropriately when we interpret the statements in the book of Genesis regarding the paradise planted by God. Celsus, moreover, has often mocked at the subject of a resurrection, a doctrine which he did not understand. On the present occasion, not satisfied with what he formerly said, he adds, "And there is said to be a resurrection of the flesh by means of the tree;" not understanding, I think, the symbolic expression that through the tree came death, and through the tree comes life, because death was in Adam, and life in Christ. Next he scoffs at the tree, attacking it on two grounds and saying, "For this reason is the tree introduced, either because our teacher was nailed to a cross, or because he was a carpenter by trade;" not observing that the tree of life is mentioned in the Mosaic writings, and being blind also to this, that in none of the Gospels current in the Churches is Jesus Himself ever described as being a carpenter.

...not be separated from each other unless the body and soul themselves are separated. In the end, the knowledge of good and evil was given at the same time to the first man. And when he understood this, he was immediately driven out of the holy place where there is no evil. For when he was occupied only with what was good, he did not know that this very thing was good. But after he had received the knowledge of good and evil, it was no longer lawful for him to remain in that place of happiness. So he was banished to this common world, so that he might experience both things at once, since he had come to know the nature of both at once. It is clear, therefore, that wisdom has been given to man so that he may distinguish good from evil, so that he may tell the difference between what is beneficial and what is harmful, between what is useful and what is useless, so that he may have judgment and careful thought about what he should guard against, what he should desire, what he should avoid, and what he should follow.

Since whatever he reaches out his hand to will be fitting and suited to nature. So if someone were to place a most excellent dinner before infants who do not yet have taste, it is clear that each one would want whatever impulse, hunger, or even accident draws him to. And whatever they take would be useful and healthy for them. What harm, then, would it be for them always to remain as they are, always infants and unfamiliar with life? But if you add a mixture of bitter things, or useless things, or even poisonous things, they are clearly deceived through their ignorance of good and evil, unless wisdom is added to them, so that they may reject evil things and choose good things.
