Pope John Paul II gave a great teaching on Adam and Eve and the Tree of the Knowledge of Good and Evil. Thought it might have been in “The Theology of the Body” but couldn’t find it there. So I’ll just give it as good as my memory allows!
The Pope spoke of Adam’s time in the garden, the freedoms, learning who he was - human, not animal. And as a human, discovering his superiority over being an animal. But it was important for man to know his limitations also - that he is inferior to God. It is God alone who determines good and evil. When Adam and Eve ate of the Tree of Knowledge of Good and Evil, they were usurping God’s role.
