Today’s Catechism sections discuss the consequences of the first sin – our struggle between good and evil. The supplemental material comes from the Pastoral Constitution, “Guadium et Spes”.

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

403 Following St. Paul, the Church has always taught that the overwhelming misery which oppresses men and their inclination towards evil and death cannot be understood apart from their connection with Adam's sin and the fact that he has transmitted to us a sin with which we are all born afflicted, a sin which is the "death of the soul".291 Because of this certainty of faith, the Church baptizes for the remission of sins even tiny infants who have not committed personal sin.292

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.

406 The Church's teaching on the transmission of original sin was articulated more precisely in the fifth century, especially under the impulse of St. Augustine's reflections against Pelagianism, and in the sixteenth century, in opposition to the Protestant Reformation. Pelagius held that man could, by the natural power of free will and without the necessary help of God's grace, lead a morally good life; he thus reduced the influence of Adam's fault to bad example. The first Protestant reformers, on the contrary, taught that original sin has radically perverted man and destroyed his freedom; they identified the sin inherited by each man with the tendency to evil (concupiscentia), which would be insurmountable. The Church pronounced on the meaning of the data of Revelation on original sin especially at the second Council of Orange (529)296 and at the Council of Trent (1546).297

A hard battle. . .

407 The doctrine of original sin, closely connected with that of redemption by Christ, provides lucid discernment of man's situation and activity in the world. By our first parents' sin, the devil has acquired a certain domination over man, even though man remains free. Original sin entails "captivity under the power of him who thenceforth had the power of death, that is, the devil".298 Ignorance of the fact that man has a wounded nature inclined to evil gives rise to serious errors in the areas of education, politics, social action299 and morals.

408 The consequences of original sin and of all men's personal sins put the world as a whole in the sinful condition aptly described in St. John's expression, "the sin of the world".300 This expression can also refer to the negative influence exerted on people by communal situations and social structures that are the fruit of men's sins.301

409 This dramatic situation of "the whole world [which] is in the power of the evil one"302 makes man's life a battle:

The whole of man's history has been the story of dour combat with the powers of evil, stretching, so our Lord tells us, from the very dawn of history until the last day. Finding himself in the midst of the battlefield man has to struggle to do what is right, and it is at great cost to himself, and aided by God's grace, that he succeeds in achieving his own inner integrity.303


419 "We therefore hold, with the Council of Trent, that original sin is transmitted with human nature, "by propagation, not by imitation" and that it is. . . 'proper to each'" (Paul VI, CPG # 16).

The Pastoral Constitution, “Guadium et Spes” (13) discusses the inclination man has toward sin and his struggle between good and evil:

13. Although he was made by God in a state of holiness, from the very onset of his history man abused his liberty, at the urging of the Evil One. Man set himself against God and sought to attain his goal apart from God. Although they knew God, they did not glorify Him as God, but their senseless minds were darkened and they served the creature rather than the Creator.(3) What divine revelation makes known to us agrees with experience. Examining his heart, man finds that he has inclinations toward evil too, and is engulfed by manifold ills which cannot come from his good Creator. Often refusing to acknowledge God as his beginning, man has disrupted also his proper relationship to his own ultimate goal as well as his whole relationship toward himself and others and all created things.

Therefore man is split within himself. As a result, all of human life, whether individual or collective, shows itself to be a dramatic struggle between good and evil, between light and darkness. Indeed, man finds that by himself he is incapable of battling the assaults of evil successfully, so that everyone feels as though he is bound by chains. But the Lord Himself came to free and strengthen man, renewing him inwardly and casting out that "prince of this world" (John 12:31) who held him in the bondage of sin.(4) For sin has diminished man, blocking his path to fulfillment.

The call to grandeur and the depths of misery, both of which are a part of human experience, find their ultimate and simultaneous explanation in the light of this revelation.
