The Adam and Eve stories are the first primordial stories that were passed down through Jewish generations. The creation accounts of Genesis are not history books; but rather literary forms employed to describe primordial creation, and to present universal religious themes: that of the fatherhood of God, the free will of man, the disobedience of man, and the chance for salvation. The reader is not supposed to ask questions like, “who were Cain and Abel’s wives?” None of the biblical writers in fact know precisely how many people there were, or how things started out. Again, the earliest stories known concerned Adam and Eve and their family. No stories invovled other people, although of course a reasonable person reading seeking out historical facts would have to assume there were other people around at the time.
None of the Vatican statements on Adam and Eve are conclusive, but are somewhat vaguely worded, so as to verify the Adam and Eve story–that real primordial events are described–but without accounting for all associated historical details. We have to use our brains a little when reading this stuff, or we can begin to sink into the type of so-called thinking that avers there were no dinosaurs because they are not mentioned in the bible, there was no rain before the flood, etc.
…or this?
CCC 389
389 The doctrine of original sin is, so to speak, the “reverse side” of the Good News that Jesus is the Saviour of all men, that all need salvation and that salvation is offered to all through Christ. The Church, which has the mind of Christ,263 knows very well that we cannot tamper with the revelation of original sin without undermining the mystery of Christ.
CCC 54-55
54 "God, who creates and conserves all things by his Word, provides men with constant evidence of himself in created realities, and furthermore, wishing to open up the way to heavenly salvation - he manifested himself to our first parents from the very beginning."6 He invited them to intimate communion with himself and clothed them with resplendent grace and justice.
55 This revelation was not broken off by our first parents’ sin. "After the fall, (God) buoyed them up with the hope of salvation, by promising redemption; and he has never ceased to show his solicitude for the human race. For he wishes to give eternal life to all those who seek salvation by patience in well-doing."7
CCC 410-412
410 After his fall, man was not abandoned by God. On the contrary, God calls him and in a mysterious way heralds the coming victory over evil and his restoration from his fall.304 This passage in Genesis is called the Protoevangelium (“first gospel”): the first announcement of the Messiah and Redeemer, of a battle between the serpent and the Woman, and of the final victory of a descendant of hers.
411 The Christian tradition sees in this passage an announcement of the “New Adam” who, because he “became obedient unto death, even death on a cross”, makes amends superabundantly for the disobedience, of Adam.305 Furthermore many Fathers and Doctors of the Church have seen the woman announced in the “Proto-evangelium” as Mary, the mother of Christ, the “new Eve”. Mary benefited first of all and uniquely from Christ’s victory over sin: she was preserved from all stain of original sin and by a special grace of God committed no sin of any kind during her whole earthly life.306
412 But why did God not prevent the first man from sinning? St. Leo the Great responds, "Christ’s inexpressible grace gave us blessings better than those the demon’s envy had taken away."307 and St. Thomas Aquinas wrote, "There is nothing to prevent human nature’s being raised up to something greater, even after sin; God permits evil in order to draw forth some greater good. Thus St. Paul says, ‘Where sin increased, grace abounded all the more’; and the Exsultet sings, ‘O happy fault,. . . which gained for us so great a Redeemer!’"308
CCC 388
388 With the progress of Revelation, the reality of sin is also illuminated. Although to some extent the People of God in the Old Testament had tried to understand the pathos of the human condition in the light of the history of the fall narrated in Genesis, they could not grasp this story’s ultimate meaning, which is revealed only in the light of the death and Resurrection of Jesus Christ.261 We must know Christ as the source of grace in order to know Adam as the source of sin. the Spirit-Paraclete, sent by the risen Christ, came to “convict the world concerning sin”,262 by revealing him who is its Redeemer.
CCC 404
404 How did the sin of Adam become the sin of all his descendants? the whole human race is in Adam “as one body of one man”.293 By this “unity of the human race” all men are implicated in Adam’s sin, as all are implicated in Christ’s justice. Still, the transmission of original sin is a mystery that we cannot fully understand. But we do know by Revelation that Adam had received original holiness and justice not for himself alone, but for all human nature. By yielding to the tempter, Adam and Eve committed a personal sin, but this sin affected the human nature that they would then transmit in a fallen state.294 It is a sin which will be transmitted by propagation to all mankind, that is, by the transmission of a human nature deprived of original holiness and justice. and that is why original sin is called “sin” only in an analogical sense: it is a sin “contracted” and not “committed” - a state and not an act.
