A literal interpretation of holy writings soon leads to confusion, obscures the truth, and makes it unnecessarily hard for rational individuals to realize the spiritual truths enshrined therein.
The stories of Adam and Eve, Noah, Moses provide spiritual teachings, such as: “God the Creator”, “God the Protector”, “God the Provider” - they are not historical accounts.
In this day, now that Christ has returned, such stories, and the teachings they provide can be viewed as the necessary steps and fundamental building blocks of our current task: to build the Kingdom of God on Earth.
