[390] The account of the fall in Genesis 3 uses figurative language, but affirms a primeval event, a deed that took place at the beginning of the history of man . Revelation gives us the certainty of faith that the whole of human history is marked by the original fault freely committed by our first parents.

III. ORIGINAL SIN
Freedom put to the test
[396] God created man in his image and established him in his friendship. A spiritual creature, man can live this friendship only in free submission to God. The prohibition against eating “of the tree of the knowledge of good and evil” spells this out: “for in the day that you eat of it, you shall die.” The “tree of the knowledge of good and evil” symbolically evokes the insurmountable limits that man, being a creature, must freely recognize and respect with trust. Man is dependent on his Creator, and subject to the laws of creation and to the moral norms that govern the use of freedom.
Man’s first sin
[397] Man, tempted by the devil, let his trust in his Creator die in his heart and, abusing his freedom, disobeyed God’s command. This is what man’s first sin consisted of. All subsequent sin would be disobedience toward God and lack of trust in his goodness.
[398] In that sin man preferred himself to God and by that very act scorned him. He chose himself over and against God, against the requirements of his creaturely status and therefore against his own good. Constituted in a state of holiness, man was destined to be fully “divinized” by God in glory. Seduced by the devil, he wanted to “be like God”, but “without God, before God, and not in accordance with God”.
399 Scripture portrays the tragic consequences of this first disobedience. Adam and Eve immediately lose the grace of original holiness.280 They become afraid of the God of whom they have conceived a distorted image - that of a God jealous of his prerogatives.
[400] The harmony in which they had found themselves, thanks to original justice, is now destroyed: the control of the soul’s spiritual faculties over the body is shattered; the union of man and woman becomes subject to tensions, their relations henceforth marked by lust and domination. Harmony with creation is broken: visible creation has become alien and hostile to man. Because of man, creation is now subject “to its bondage to decay”. Finally, the consequence explicitly foretold for this disobedience will come true: man will “return to the ground”, for out of it he was taken. Death makes its entrance into human history .
[401] After that first sin, the world is virtually inundated by sin…
