IV. MAN IN PARADISE
374 The first man was not only created good, but was also established in friendship with his Creator and in harmony with himself and with the creation around him, in a state that would be surpassed only by the glory of the new creation in Christ.
375 The Church, interpreting the symbolism of biblical language in an authentic way, in the light of the New Testament and Tradition, teaches that our first parents, Adam and Eve, were constituted in an original “state of holiness and justice”.250 This grace of original holiness was “to share in. . .divine life”.251
376 By the radiance of this grace all dimensions of man’s life were confirmed. As long as he remained in the divine intimacy, man would not have to suffer or die.252 The inner harmony of the human person, the harmony between man and woman,253 and finally the harmony between the first couple and all creation, comprised the state called “original justice”.
377 The “mastery” over the world that God offered man from the beginning was realized above all within man himself: mastery of self. The first man was unimpaired and ordered in his whole being because he was free from the triple concupiscence254 that subjugates him to the pleasures of the senses, covetousness for earthly goods, and self-assertion, contrary to the dictates of reason.
378 The sign of man’s familiarity with God is that God places him in the garden.255 There he lives “to till it and keep it”. Work is not yet a burden,256 but rather the collaboration of man and woman with God in perfecting the visible creation.
379 This entire harmony of original justice, foreseen for man in God’s plan, will be lost by the sin of our first parents
Paragraph 7. The Fall
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.278 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”.279
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.282 Harmony with creation is broken: visible creation has become alien and hostile to man.283 Because of man, creation is now subject “to its bondage to decay”.284 Finally, the consequence explicitly foretold for this disobedience will come true: man will “return to the ground”,285 for out of it he was taken. Death makes its entrance into human history.286
What Revelation makes known to us is confirmed by our own experience. For when man looks into his own heart he finds that he is drawn towards what is wrong and sunk in many evils which cannot come from his good creator. Often refusing to acknowledge God as his source, man has also upset the relationship which should link him to his last end, and at the same time he has broken the right order that should reign within himself as well as between himself and other men and all creatures.288
The consequences of Adam’s sin for humanity
402 All men are implicated in Adam’s sin, as St. Paul affirms: “By one man’s disobedience many (that is, all men) were made sinners”: "sin came into the world through one man and death through sin, and so death spread to all men because all men sinned."289 The Apostle contrasts the universality of sin and death with the universality of salvation in Christ. "Then as one man’s trespass led to condemnation for all men, so one man’s act of righteousness leads to acquittal and life for all men."290
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.
405 Although it is proper to each individual,295 original sin does not have the character of a personal fault in any of Adam’s descendants. It is a deprivation of original holiness and justice, but human nature has not been totally corrupted: it is wounded in the natural powers proper to it, subject to ignorance, suffering and the dominion of death, and inclined to sin - an inclination to evil that is called concupiscence". Baptism, by imparting the life of Christ’s grace, erases original sin and turns a man back towards God, but the consequences for nature, weakened and inclined to evil, persist in man and summon him to spiritual battle.
