What good purpose did it serve at all? Why did God make it so? Why did he allow the serpent to exist in Eden? Why didn’t he tell Adam and Eve exactly what was going to happen in detail if they did not obey his command not to eat of it? Why did he not warn them of the lie Eve was going to be told from the serpent about it? What would have happened if Adam refused to eat of it even after Eve insisted he do so?
A little lengthy, but hopefully will be helpful. It addresses most of the questions above.
God planted the garden of Eden, with the tree of life and the tree of the knowledge of good and evil in it. Genesis 2 explains the duties and commands that God placed under Adam’s care. It states that, “The Lord God took the man and put him in the garden of Eden to till and keep it. And the Lord God commanded the man, saying, ‘you may freely eat of every tree of the garden; but of the tree of the knowledge of good and evil you shall not eat, for in the day that you eat of it you shall die’” (Gen 2:15-17). Adam’s duties in the garden along with God’s command to Adam reveal a number of important points.
Adam must fulfill the duties of priest-king in the cosmic covenant and husband in his marital covenant with Eve. The priestly duties of Adam are of concern here. Adam’s duty in the garden was to “till” and “keep” it. The Hebrew word for “keep” is shamar, which means “to guard”. From this, it is clear that Adam was alerted to the possibility that he might be called to exercise his priestly duty by guarding the garden from potential intruders. God’s warning to Adam that, “in the day that you eat of it you shall die” is perfectly clear. Though immortality was one of the preternatural gifts given to Adam, it was given as a conditional gift. That is, Adam had to fulfill the requirement placed upon him by God in order to maintain it. The requirement was that Adam remained obedient to God’s prohibition against eating from the tree of the knowledge of good and evil. So, Adam possessed potential immortality, but knew that the possibility of death existed.
Adam and Eve had been freely given all that they could ever ask for from God. They were given supernatural grace, the preternatural gifts, a life of paradise in the garden of Eden, and each other as husband and wife. Supernatural grace made them partakers in the divine life as adopted sons and daughters of God. All of this was freely bestowed upon them by God as a completely gratuitous gift. To keep this share in divine life, all they had to do was obey the command of God by not eating from the tree of the knowledge of good and evil. They had been given all the necessary tools to do so.
It is important to remember that all of these wonderful gifts, freely bestowed upon Adam and Eve, were not their final end. God wanted to and planned to give them so much more. Their final end was supposed to be an unending life of perfect happiness, produced by immediate union with and direct sight of God, by the beatific vision. The paradise of the garden of Eden, along with all the other gifts given to Adam and Eve, was set up by God as a probationary state of testing.
God’s prohibition against Adam and Eve eating from the tree of the knowledge of good and evil is a very important part of the story of the fall. The tree, “symbolically evokes the insurmountable limits that man, being a creature, must freely recognize and respect with trust. Man is dependent on his Creator and subject to the laws of creation and to the moral norms that govern the use of freedom” (CCC 396). This tree would be central to the test that Adam and Eve were about to endure.
Adam was called to make a sacrifice of obedience and faith to God in return for the earthly paradise that God gratuitously bestowed upon him. God’s prohibition placed on the freedom of man to eat from this one tree demanded obedience and complete submission on the part of man. Disobedience on the part of man meant the loss of the supernatural and preternatural gifts that God had given him. This implies that obedience would have meant the retention of these gifts until man entered the world to come. There was, therefore, an implied pact or covenant between God and Adam, the observance of which by Adam was a grave obligation. It was in this obligation that Adam would fail.
God actually placed this tree in the center of the garden of Eden. This can be seen as a reminder to man that he is not God, and that God must always remain the center of man’s world. In this way, the tree can be seen as sacramental because it is a physical object that conveys a spiritual reality. Obedience to God’s prohibition was required of Adam and Eve in this probationary state of testing. This probationary state of testing was meant to strengthen and confirm Adam and Eve in righteousness so they could face the beatific vision worthily. The tree of the knowledge of good and evil plays a central role in the test that Adam and Eve are about to face in Genesis 3.
The Catechism of the Catholic Church advises how one should read the account of the fall. It states that, “The account of the fall in Genesis 3 uses figurative language, but affirms a primeval event, a deed that took place at the beginning of the history of man. Revelation gives us the certainty of faith that the whole of human history is marked by the original fault freely committed by our first parents” (CCC 390). Genesis 3 should help answer the question of why Adam sinned.
Genesis 3 tells the story of the temptation and fall of man. The story begins with the serpent subtly convincing Eve to eat of the forbidden fruit from the tree of the knowledge of good and evil. The serpent told the woman that they would not die if they ate of the tree, and that their eyes would be opened so that they would be like God. The woman took and ate of the fruit and gave some to her husband, and he ate (Gen 3:1-7). This transgression of God’s command was the first sin of man, but what was the cause of this sin?
It is important to keep in mind, that although man had not yet sinned, the angelic fall had already occurred. The reader is reminded of this when temptation enters the story in the form of a serpent. Temptation presents as good, something that is actually evil. This could not have come from within man in his pre-fallen state. It is important to note that temptation came to pre-fallen man from the outside. Sacred Scripture (see Rev 12:9, 20:2, & Jn 8:44) and the Tradition of the Church both identify the serpent with Satan himself. When he spoke to Eve, the serpent twisted God’s words into a confusing web of half-truths that put Eve on the defensive. This is the time when Adam should have intervened and fulfilled his duty to guard the garden and protect his new wife. The serpent is the intruder that God warned Adam about by giving him the duty to guard the garden. Why did Adam not act?
The Hebrew word for serpent, nahash, often refers to something that bites with venom and poses a threat to mortal life. Adam knew that he possessed eternal life, but he also knew that he could die. The serpent said that they would not die if they ate from the tree. In this statement the serpent implies that he will kill them if they do not eat the forbidden fruit. Adam did not act and fulfill his duty to protect the garden and his new bride because of the fear of physical suffering and death. It is the fear of physical suffering and death that caused Adam to fall before the sins of pride and disobedience came into the picture.
The fear of physical suffering and death is what caused Adam to fall to the sins of pride and disobedience. Adam had to make a choice between the created gifts that were over-abundantly bestowed upon him and his faith in God. It was in turning away from God in pride and disobedience that Adam fell. The results of the first sin can be seen to be immediately devastating.
When man turned away from God at the fall he lost the preternatural gifts and supernatural grace. Man’s nature was not destroyed, but it was wounded and this hindered man’s ability to strive for the moral life. Man was certainly destitute, but God would not leave man alone. His gifts of excess will forever overwhelm man’s being beyond imagination.
After the fall God handed down severe consequences to Adam and Eve, which included pain, suffering, and death. He next cursed the serpent and promised to send a Savior to redeem fallen man. It was suffering and death that Adam was unwilling to endure when he turned from God and betrayed his duties as priest-king and husband. For this reason, it would take much suffering and even death on a cross to reverse the curse (original sin) that Adam brought to humanity because of his sin.
The perfection of the redemptive work of Christ points to how Adam was called to act when he fell to sin. Original sin explains the trouble with human life and redemption explains the remedy.
The act of Christ’s redemption shows how Adam should have acted. It is the complete and sacrificial gift of self that Christ made on the cross that was called for from Adam in the garden. Adam needed to embrace the tree of life with faith that the Father would not abandon him, in the same way that Christ embraced the tree of life, his cross. Adam needed to make a complete gift of self, even to the point of suffering and death, in order to truly love as God willed. Adam needed to open himself up fully to the will of God who was dwelling within him. If he had done so, he would have passed the test and overcome temptation. His reward would surely have been eternal life in heavenly glory.
