No, I’m saying that choosing to eat of the Tree of the Knowledge of Good and Evil was an example of a good act chosen at the wrong time or under the wrong circumstances out of lack of faith. No, I don’t see that it can be presumed that Adam and Eve never could have been allowed to eat from the Tree. They didn’t know that, one way or the other. They were told it would be deadly under the present circumstances and were told no more. They were told enough to act according to God’s plan.
I don’t think God made the Tree of the Knowledge of Good and Evil–or any good thing that is deadly if used at the wrong time or in the wrong way–as a way to trap Adam and Even into sin. We have free will in order to share in the life of God. Like the Trinity, however, the divine life requires that free will is used within a framework of relationship. In our relationship with God, we must have faith–trust that the divine law is superior to our own capacity to choose. Even within the Trinity, after all, there is no contention. The Three Persons are one God: being of one mind is the nature of being in a relationship of love. It is the way the moral universe is built.
Contrast this with the way Adam and Eve reacted to being questioned about their decision–immediately, they point fingers. Immediately, they distance themselves from their decision by shifting blame. This is what evil does: it destroys unity and introduces contention and dissension. The suggestion of the snake, too, was a temptation to lose faith, was it not? The first step towards sin is losing faith in the absolute goodness of the divine law.
The exercise of free will and a correctly-formed conscience, in contrast, is seen in Gethsemane. Our Lord did not look forward to the Passion. He didn’t want to be falsely accused, physically assaulted, insulted, and eventually killed. This was a correct prudential judgment, the same judgment he has used all the times the crowd wanted to kill him and he slipped away. In this case, however, he knew with certainty that there was a overriding concern with regards to the will of the Father that made it an exception. In this case, his prudential judgment was overridden by faith that in this case slipping away was not in God’s plan. In this case, he had to remain, testify to the truth by his actions, and in so doing fulfill the will of the Father, even to death, a death he knew was certain because he understood the situation fully. This was the fulfillment of the journey of faith begun in Abraham (whose righteousness was accounted according to his willingness to trust in both the promises and the commands of God).
Now, if you want to see the Tree of the Knowledge of Good and Evil as something good we can appreciate but can never achieve ourselves, I don’t see why that would be a wrong way to look at it. For instance, you could say it was a physical analogy of the actual sovereignty of God. We can appreciate the divine law, but we don’t get to write it. Sure, that works, too.
What I don’t think works is looking at the Tree of the Knowledge of Good and Evil and as inherently bad thing, rather than a good thing used in the wrong way.
