Eating fruit was not the original sin. Adultery was. How could the serpent have a sexual union with Eve? It was only after God cursed it that he became a snake. “Upon thy belly shalt thou go (he didn’t go on his belly before this) and dust thou shalt eat all the days of thy life.” (Genesis 3:14).
Before this, he was more subtle than any beasts (not reptiles) of the field (Genesis 3:1). He could also talk, reason and persuade. (Genesis 3:1-5).
He walked upright, he talked and he was intelligent. He was between the animal kingdom and the human. Satan was in the garden (Ezekiel 28:13-17) and used the Serpent to mix his seed with the woman’s seed. The sin exposing their nakedness was adultery.
Apples didn’t cause them shame; it was the loss of innocence. They didn’t
cover their mouths. The Serpent ate with Eve, then she shared with her husband. Two children were born. One evil and one good. Cain was the son of the devil (St John 8:44), the wicked one (1 John 3:12). He was never recorded in the genealogy of Adam. Genealogies do not differ good sons from bad, they are based on the identity of the biological father.
Adam was the son of God (St Luke 3:38) and his son was Seth, who took the place of Abel (Genesis 5:3 and Jude 14). Eve is the mother of all living (Genesis 3:20) but Adam was not the father of all living. He knew her for the second time and she had her third son (Genesis 4:24).
Jesus had to be born of a virgin – the Remedy for our sin bypassed the original sin. We are shaped in iniquity and conceived in sin (Psalms 51:5).
Men are typed as trees. (Psalms 1:1-3) Women are typed as a Garden enclosed.(Song of Solomon 4:12) Eves punishment affected her in childbearing (Genesis 3:16)
The fruit of the Womb are children. (Psalms 127:3)…an adulterous woman, she eateth, and wipeth her mouth…. (Proverbs 30:20)
The idea that Eve ate an apple is a trumped-up doctrine by a church that places no value in the scriptures. Much of the Bible is written in parables and types and shadows, but this is no reason to believe fables and church dogma instead of the Word of God.
