Based on the writings of Ellen White, Adam and Eve were not created mortal. Their immortality was conditional upon their obedience to God and their access to the tree of life.
Here's a breakdown of what the texts indicate:
* **Death was a consequence of sin:** Ellen White states that their disobedience "brought sin and sorrow and death into the world" (
SJ 43.6). The transgression of God's law "separated man from God and opened the floodgates of death and untold woe upon our world" (
SC 33.1). This shows that death was not their original state.
* **The Tree of Life perpetuated immortality:** The purpose of the tree of life was to sustain their immortal state. After they sinned, they were barred from the garden specifically to prevent them from accessing this tree. "The tree of life was to perpetuate immortality. I heard an angel ask, Who of the family of Adam have passed that flaming sword, and have partaken of the tree of life? I heard another angel answer, Not one of the family of Adam have passed that flaming sword, and partaken of that tree; therefore there is not an immortal sinner" (1SG 113).
* **They were created perfect and sinless:** Before the fall, Adam and Eve were described as perfect beings. "The Lord made man upright in the beginning. He was created with a perfectly balanced mind, the size and strength of all its organs being perfectly developed. Adam was a perfect type of man" (
3T 72.1). They were "clothed with a covering of light and glory, such as the angels wear. So long as they lived in obedience to God, this robe of light continued to enshroud them" (
PP 45.3).
In summary, Adam and Eve were created with conditional immortality, which they would have retained as long as they remained obedient and had access to the tree of life. Mortality was the direct result of their transgression.
