The Traditional Reading — and What's Missing Why the standard "original sin" reading doesn't work in the Book of Mormon
The traditional Christian reading of Genesis — developed most explicitly by Augustine and forming the backbone of much Western theology — treats the Fall as catastrophic. Adam and Eve were given a perfect garden. They disobeyed. Sin entered the world, mortality entered, suffering entered, the entire creation was corrupted. The Atonement is required to repair the damage that the Fall caused. Eve, in this reading, is often the primary villain of the story: she listened to the serpent, she ate, she gave the fruit to Adam. The Fall is her fault, and the consequences fall on all humanity.
Lehi does not read the story this way. He reads it as a story in which the Fall was not a disaster but a necessity — not merely permitted by God but required for the plan of salvation to function. His argument is built on a simple logic: without the Fall, there would be no mortality; without mortality, there would be no children; without children, there would be no humanity in the full sense; and without the conditions of mortality — opposition, choice, consequences — there would be no genuine joy. The perfect garden was not a permanent destination. It was a starting point.
"And now, behold, if Adam had not transgressed he would not have fallen, but he would have remained in the garden of Eden. And all things which were created must have remained in the same state in which they were after they were created; and they must have remained forever, and had no end. And they would have had no children; wherefore they would have remained in a state of innocence, having no joy, for they knew no misery; doing no good, for they knew no sin."
2 Nephi 2:22–23 Without the Fall: no children, no opposition, no real choice, no real joy. The garden was stasis. The Fall was movement. And movement was what the plan required.
