It was foretold that the struggle between humanity and the serpent, that is, between man and the forces of evil and death, would continue throughout history.
It was also foretold, however, that the “offspring” of a woman would one day triumph and would crush the head of the serpent to death; it was foretold that the offspring of the woman – and in this offspring the woman and the mother herself – would be victorious and that thus, through man, God would triumph.
If we set ourselves with the believing and praying Church to listen to this text, then we can begin to understand what original sin, inherited sin, is and also what the protection against this inherited sin is, what redemption is.
What picture does this passage show us? The human being does not trust God. Tempted by the serpent, he harbors the suspicion that in the end, God takes something away from his life, that God is a rival who curtails our freedom and that we will be fully human only when we have cast him aside; in brief, that only in this way can we fully achieve our freedom.
The human being lives in the suspicion that God’s love creates a dependence and that he must rid himself of this dependency if he is to be fully himself. Man does not want to receive his existence and the fullness of his life from God.
He himself wants to obtain from the tree of knowledge the power to shape the world, to make himself a god, raising himself to God’s level, and to overcome death and darkness with his own efforts. He does not want to rely on love that to him seems untrustworthy; he relies solely on his own knowledge since it confers power upon him. Rather than on love, he sets his sights on power, with which he desires to take his own life autonomously in hand. And in doing so, he trusts in deceit rather than in truth and thereby sinks with his life into emptiness, into death.
Love is not dependence but a gift that makes us live. The freedom of a human being is the freedom of a limited being, and therefore is itself limited. We can possess it only as a shared freedom, in the communion of freedom: only if we live in the right way, with one another and for one another, can freedom develop.
We live in the right way if we live in accordance with the truth of our being, and that is, in accordance with God’s will. For God’s will is not a law for the human being imposed from the outside and that constrains him, but the intrinsic measure of his nature, a measure that is engraved within him and makes him the image of God, hence, a free creature.
If we live in opposition to love and against the truth – in opposition to God – then we destroy one another and destroy the world. Then we do not find life but act in the interests of death. All this is recounted with immortal images in the history of the original fall of man and the expulsion of man from the earthly Paradise. – Benedict XVI, Homily, 2005.
