In Mormonism, the Fall of Adam and Eve is seen as a necessary and even positive event. Leaders have taught that Adam partook of the fruit voluntarily, “that men might be” — meaning that humanity could only come into existence if Adam and Eve became mortal. They believe Adam and Eve could not have children until they ate from the tree of knowledge of good and evil. For this reason, Mormons often speak of owing Adam gratitude for his choice (2 Nephi 2:22–25).
LDS teaching says God gave Adam and Eve two conflicting commandments: to be fruitful and multiply, and not to eat of the fruit. By eating, they were said to have chosen correctly, using their agency to keep the greater command. Thus, the Fall introduced mortality, death, and suffering, but also opened the door for human progress and eternal families.
This view stands in sharp contrast to biblical Christianity, which sees the Fall as the greatest catastrophe in human history. Through Adam, sin and death entered the world (Romans 5:12–19), and mankind became totally corrupt and separated from God (Romans 3:10–12). Far from being a blessing, the Fall reveals humanity’s desperate need for redemption through Christ.
