2. "Disobedience" means precisely going beyond that limit, which remains impassable to the will and the freedom of man as a created being. For God the Creator is the one definitive source of the moral order in the world created by him. Man cannot decide by himself what is good and what is evil-cannot "know good and evil, like God." In the created world God indeed remains the first and sovereign source for deciding about good and evil, through the intimate truth of being, which is the reflection of the Word, the eternal Son, consubstantial with the Father. To man, created to the image of God, the Holy Spirit gives the gift of conscience, so that in this conscience the image may faithfully reflect its model, which is both Wisdom and eternal Law, the source of the moral order in man and in the world. "Disobedience," as the original dimension of sin, means the rejection of this source, through man's claim to become an independent and exclusive source for deciding about good and evil The Spirit who "searches the depths of God," and who at the same time is for man the light of conscience and the source of the moral order, knows in all its fullness this dimension of the sin inscribed in the mystery of man's beginning_. Man's disobedience, nevertheless, always means a turning away from God, and in a certain sense the closing up of human freedom in his regard. It also means a certain opening of this freedom-of the human mind and will-to the one who is the "father of lies." This act of conscious choice is not only "disobedience" but also involves a certain consent to the motivation which was contained in the first temptation to sin and which is unceasingly renewed during the whole history of man on earth: "For God knows that when you eat of it your eyes will be opened, and you will be like God, knowing good and evil." (Papal Encyclical, Dominum et Vivificantem, 18 May 1986).
