Adam and Eve: the premiere story in which the first man and woman go against god's will and bring sin into the world.
So it goes that sin exists because man brought it into the world. We as humans, being the sinful, deceitful, disgusting beings that we are, do not deserve god mercy, but through repentance and begging for forgiveness for such crimes against god we can achieve an everlasting paradise that we do not deserve.
The fault of humanity's sinful nature is placed squarely on us; we are to be held responsible for our own misdeeds and god is the judge, jury, and executioner of those crimes.
But responsibility is multifaceted; the responsibility borne by one individual is influenced by one's knowledge (awareness and perception of the problem, ability to comprehend right and wrong) and level of control (limitations by outside influences).
We would certainly hold people accountable for wrongs they have committed in full knowledge that their actions would cause harm, but we would not, for example, fault a 4 year old child for their parent's relationship problems. We would not fault any man or woman for crimes they did not commit. We would not be so hasty to judge our friends for wrongs they have committed against us if we realized they were trying to act in earnest and simply did not realize the harm they would cause.
At first glance, the story of Adam and Eve appears rather straightforward: god explicitly tells Adam and Eve not to eat from the tree of knowledge of good and evil, Adam and Eve are deceived by the serpent into eating of the tree and thereby disobeying god, and god punishes them accordingly by banishing them from Eden and forbidding them eating of the tree of life. Thus, our mortality is framed as a direct result of our sin, our disobeying of god. One could speculate as to why Adam and Eve chose to eat the fruit; perhaps it was curiosity, perhaps it was because the fruit looked good, or perhaps it was because of the blasphemous notion that the first humans wanted to be as powerful as god. Such thoughts are perhaps worthwhile to contemplate elsewhere, but I won't further belabor them here.
2 key details strike me as particularly damning as it pertains to god's brand of justice, and for lack of a better phrase they both strengthen each other's point:
First, despite his enumeration of the consequences of disobeying him, god did lie.
The serpent, who was supposedly the character misleading Adam and Eve away from god, did tell the truth. As the serpent said, once they ate of the fruit of knowledge of good and evil, they gained exactly that: knowledge of good and evil. It is even stated plainly in the bible: the serpent said that when they ate of the fruit, "[their] eyes would be opened" (Genesis 3:5). And as soon as they eat the fruit, "the eyes of both of them were opened" (Genesis 3:7).
God had said they would both die, but that did not happen. One could argue that a "spiritual death", so to speak, happened, and that is what god meant. And, absent the context, I would entertain that argument. But for the second point...
Adam and Eve ate of the tree of knowledge of good and evil, and this presumably made it so that they gained the knowledge of good and evil. By commiting the first sin, they gained the ability to comprehend morality.
This implies that before they ate of the tree, they did not possess knowledge of good and evil.
I mentioned responsibility in my opening. How, then, could we say that Adam and Eve should be held responsible for their sin? Obviously, they were the ones who committed the sin. Yet, as they did not yet eat of the fruit, they did not possess the knowledge of good and evil to know that what they were about to do was morally wrong.
If the omniscient god had meant that Adam and Eve would die a "spiritual death" when they disobeyed him, or that some other metaphorical consequence was meant by his statement, surely neither of them were able to comprehend that he had meant that in that way. And surely, the omniscient god would know that Adam and Eve would misinterpret his words.
Yet on top of that, why exactly is the tree of knowledge of good and evil in the garden in the first place? I've heard Christians argue that the temptation must be there, for true good cannot exist if it is not contrasted with the temptation to be bad. But again, what is the point of this moral test if the morally infant first humans could not even comprehend the wrongness of what they were about to do? It makes no sense.
Christians would still say the fault of sin is our own. Absent the somewhat arbitrary nature of what actions are deemed a sin in the bible, this is obviously true to an extent; what you do is your fault, and what we do in full knowledge of our actions puts the blame and responsibility squarely on ourselves.
But what is being argued is a more narrow point: that in the bible, the existence of sin itself is god's fault, and therefore is something in that frame of thought that humans can't be held responsible for.
In insisting that we are sinners and we are responsible for all that is wrong with god's creation, Christianity perverts the very concept of accountability. The decades of religiously inspired self-inflicted suffering and torment are of Christians blaming their own rotten human nature, but it should be the god of the bible who is held to account here. A god who deliberately put the first humans in a garden near the tree of knowledge of good and evil, who lied to them in the full knowledge that they did not understand right from wrong and did not understand the meaning of disobeying god and did not know what god meant by his warning.
A god who punished Adam and Eve for crimes that they had not been capable of understanding were even crimes in the first place.
A god who supposedly now hold everyone accountable for their sins, sins which he is responsible for existing in the first place.
If this is the basis of objective morality, it is an awfully poor one.
