Art Katz warns against the temptation of seeking knowledge from the Tree of the Knowledge of Good and Evil, emphasizing that this desire leads to a false sense of superiority where individuals presume to judge right and wrong as if they were God. He highlights the danger of self-deception, where one believes they are serving God by making moral judgments, yet in reality, they unleash chaos and evil. Katz stresses that true knowledge of good and evil belongs solely to God, and when humans attempt to take on this role, they fracture their relationships with others and with God. The sermon serves as a reminder of the humility required in our understanding of morality and the importance of recognizing our limitations as humans.
