Today’s Catechism sections discuss the fall of man and the fallen angels. Supporting material comes from a general audience of Pope Benedict XVI and “City of God” by St. Augustine.
Paragraph 7. THE FALL
385 God is infinitely good and all his works are good. Yet no one can escape the experience of suffering or the evils in nature which seem to be linked to the limitations proper to creatures: and above all to the question of moral evil. Where does evil come from? "I sought whence evil comes and there was no solution", said St. Augustine,257 and his own painful quest would only be resolved by his conversion to the living God. For "the mystery of lawlessness" is clarified only in the light of the "mystery of our religion".258 The revelation of divine love in Christ manifested at the same time the extent of evil and the superabundance of grace.259 We must therefore approach the question of the origin of evil by fixing the eyes of our faith on him who alone is its conqueror.260
I. WHERE SIN ABOUNDED, GRACE ABOUNDED ALL THE MORE
The reality of sin
386 Sin is present in human history; any attempt to ignore it or to give this dark reality other names would be futile. To try to understand what sin is, one must first recognize the profound relation of man to God, for only in this relationship is the evil of sin unmasked in its true identity as humanity's rejection of God and opposition to him, even as it continues to weigh heavy on human life and history.
387 Only the light of divine Revelation clarifies the reality of sin and particularly of the sin committed at mankind's origins. Without the knowledge Revelation gives of God we cannot recognize sin clearly and are tempted to explain it as merely a developmental flaw, a psychological weakness, a mistake, or the necessary consequence of an inadequate social structure, etc. Only in the knowledge of God's plan for man can we grasp that sin is an abuse of the freedom that God gives to created persons so that they are capable of loving him and loving one another.
Original sin - an essential truth of the faith
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.
389 The doctrine of original sin is, so to speak, the "reverse side" of the Good News that Jesus is the Savior 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.
How to read the account of the fall
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.264 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.265
II. THE FALL OF THE ANGELS
391 Behind the disobedient choice of our first parents lurks a seductive voice, opposed to God, which makes them fall into death out of envy.266 Scripture and the Church's Tradition see in this being a fallen angel, called "Satan" or the "devil".267 The Church teaches that Satan was at first a good angel, made by God: "The devil and the other demons were indeed created naturally good by God, but they became evil by their own doing."268
392 Scripture speaks of a sin of these angels.269 This "fall" consists in the free choice of these created spirits, who radically and irrevocably rejected God and his reign. We find a reflection of that rebellion in the tempter's words to our first parents: "You will be like God."270 The devil "has sinned from the beginning"; he is "a liar and the father of lies".271
393 It is the irrevocable character of their choice, and not a defect in the infinite divine mercy, that makes the angels' sin unforgivable. "There is no repentance for the angels after their fall, just as there is no repentance for men after death."272
394 Scripture witnesses to the disastrous influence of the one Jesus calls "a murderer from the beginning", who would even try to divert Jesus from the mission received from his Father.273 "The reason the Son of God appeared was to destroy the works of the devil."274 In its consequences the gravest of these works was the mendacious seduction that led man to disobey God.
395 The power of Satan is, nonetheless, not infinite. He is only a creature, powerful from the fact that he is pure spirit, but still a creature. He cannot prevent the building up of God's reign. Although Satan may act in the world out of hatred for God and his kingdom in Christ Jesus, and although his action may cause grave injuries - of a spiritual nature and, indirectly, even of a physical nature - to each man and to society, the action is permitted by divine providence which with strength and gentleness guides human and cosmic history. It is a great mystery that providence should permit diabolical activity, but "we know that in everything God works for good with those who love him."275
413 "God did not make death, and he does not delight in the death of the living. . . It was through the devil's envy that death entered the world" (⇒ Wis 1:13; ⇒ 2:24).
414 Satan or the devil and the other demons are fallen angels who have freely refused to serve God and his plan. Their choice against God is definitive. They try to associate man in their revolt against God.
Pope Benedict XVI gave a great reflection on Original Sin in his general audience on December 3, 2008:
However, as people of today we must ask ourselves: what is this original sin? What does St Paul teach, what does the Church teach? Is this doctrine still sustainable today? Many think that in light of the history of evolution, there is no longer room for the doctrine of a first sin that then would have permeated the whole of human history. And, as a result, the matter of Redemption and of the Redeemer would also lose its foundation. Therefore, does original sin exist or not? In order to respond, we must distinguish between two aspects of the doctrine on original sin. There exists an empirical aspect, that is, a reality that is concrete, visible, I would say tangible to all. And an aspect of mystery concerning the ontological foundation of this event. The empirical fact is that a contradiction exists in our being. On the one hand every person knows that he must do good and intimately wants to do it. Yet at the same time he also feels the other impulse to do the contrary, to follow the path of selfishness and violence, to do only what pleases him, while also knowing that in this way he is acting against the good, against God and against his neighbor. In his Letter to the Romans St Paul expressed this contradiction in our being in this way: "I can will what is right, but I cannot do it. For I do not do the good I want, but I do the evil I do not want" (7: 18-19). This inner contradiction of our being is not a theory. Each one of us experiences it every day. And above all we always see around us the prevalence of this second will. It is enough to think of the daily news of injustice, violence, falsehood and lust. We see it every day. It is a fact.
In his great work, “City of God” (Book 22), St. Augustine comments on the fallen angels and the gift of free will to His creatures:
For it is He who in the beginning created the world full of all visible and intelligible beings, among which He created nothing better than those spirits whom He endowed with intelligence, and made capable of contemplating and enjoying Him, and united in our society, which we call the holy and heavenly city, and in which the material of their sustenance and blessedness is God Himself, as it were their common food and nourishment. It is He who gave to this intellectual nature free-will of such a kind, that if he wished to forsake God, i.e., his blessedness, misery should immediately result. It is He who, when He foreknew that certain angels would in their pride desire to suffice for their own blessedness, and would forsake their great good, did not deprive them of this power, deeming it to be more befitting His power and goodness to bring good out of evil than to prevent the evil from coming into existence. And indeed evil had never been, had not the mutable nature— mutable, though good, and created by the most high God and immutable Good, who created all things good— brought evil upon itself by sin. And this its sin is itself proof that its nature was originally good. For had it not been very good, though not equal to its Creator, the desertion of God as its light could not have been an evil to it. For as blindness is a vice of the eye, and this very fact indicates that the eye was created to see the light, and as, consequently, vice itself proves that the eye is more excellent than the other members, because it is capable of light (for on no other supposition would it be a vice of the eye to want light), so the nature which once enjoyed God teaches, even by its very vice, that it was created the best of all, since it is now miserable because it does not enjoy God. It is he who with very just punishment doomed the angels who voluntarily fell to everlasting misery, and rewarded those who continued in their attachment to the supreme good with the assurance of endless stability as the meed of their fidelity. It is He who made also man himself upright, with the same freedom of will,— an earthly animal, indeed, but fit for heaven if he remained faithful to his Creator, but destined to the misery appropriate to such a nature if he forsook Him. It is He who when He foreknew that man would in his turn sin by abandoning God and breaking His law, did not deprive him of the power of free-will, because He at the same time foresaw what good He Himself would bring out of the evil, and how from this mortal race, deservedly and justly condemned, He would by His grace collect, as now He does, a people so numerous, that He thus fills up and repairs the blank made by the fallen angels, and that thus that beloved and heavenly city is not defrauded of the full number of its citizens, but perhaps may even rejoice in a still more overflowing population.
