With Original Sin, Adam and Eve had their innocence. They had Divine Grace.
While not Catholic, a sermon given by I think JD Jakes that actually fits with Catholic teaching which may answer the question. What did Adam and Eve eat?
They ate a lie.
They bought into an untruth that by eating the forbidden fruit, they would be like God.
They bought into the lie that by eating the forbidden fruit because they believed the snake’s lie that they did not need God.
They were duped by the Liar of all liars. They discovered that they were naked.
What does being naked mean? To be naked is to be vulnerable. This was not part of the sermon; I don’t remember the name of the Catholic article where I read it. The article I read was about the importance of being open in marriage, the real meaning of being vulnerable.
After eating the fruit, Adam and Eve began to see each other differently. They put up barriers and defenses. They needed to be clothed.
There are many forms of literature with the Bible. God inspired different men at different times of history to set His truth is written form. It is meant for spiritual guidance, and not merely as a historical or science book. Scientism fails to see the truth of God’s creative hand and argues with fundamentalists who miss the forest for the trees. God continues to create every time a new child is born. He involves man and woman in the creative process.
What did God do after each day of creation? He looked over what He had created and saw that it was good. He made man in His own image and saw that it was very good. If I am made in God image, then I am made to be creative, artistic. If God took time to reflect on what He made, then I need to take time at the end of each day to reflect on my day. How have I used my time as a mechanic, carpenter, writer, farmer, or whatever mundane job I may have as part of God’s creative work? The O.T. has many passages about the need for rest, for the land to take a sabbath. What happened to land that is overworked, and not allowed to lie fallow? “What good is your earlier rising, your going later to bed, you who toil for the bread you eat?”
St. John Paul II writes in his Theology of the Body that Adam did not recognize that he was made in God’s image until he saw his reflection in Eve.
It is easy to get stuck in one passage of scripture. The Catholic Church tells us to read the Bible as a whole. Allow the O.T. to shed light upon the N.T. Allow the Holy Spirit to guide your personal reading into deeper reflection so God’s Word transforms your life and is not merely another piece of literature on the shelf that you read and argue about.
