City of God, Book XXI
Zoroaster alone is said to have laughed when he was born, and that unnatural omen portended no good to him. For he is said to have been the inventor of magical arts, though indeed they were unable to secure to him even the poor felicity of this present life against the assaults of his enemies. For, himself king of the Bactrians, he was conquered by Ninus king of the Assyrians. In short, the words of Scripture, “An heavy yoke is upon the sons of Adam, from the day that they go out of their mother’s womb till the day that they return to the mother of all things,” —these words so infallibly find fulfillment, that even the little ones, who by the layer of regeneration have been freed from the bond of original sin in which alone they were held, yet suffer many ills, and in some instances are even exposed to the assaults of evil spirits. But let us not for a moment suppose that this suffering is prejudicial to their future happiness, even though it has so increased as to sever soul from body, and to terminate their life in that early age.
Chapter 15.—That Everything Which the Grace of God Does in the Way of Rescuing Us from the Inveterate Evils in Which We are Sunk, Pertains to the Future World, in Which All Things are Made New.
Nevertheless, in the “heavy yoke that is laid upon the sons of Adam, from the day that they go out of their mother’s womb to the day that they return to the mother of all things,” there is found an admirable though painful monitor teaching us to be sober-minded, and convincing us that this life has become penal in consequence of that outrageous wickedness which was perpetrated in Paradise, and that all to which the New Testament invites belongs to that future inheritance which awaits us in the world to come, and is offered for our acceptance, as the earnest that we may, in its own due time, obtain that of which it is the pledge. Now, therefore, let us walk in hope, and let us by the spirit mortify the deeds of the flesh, and so make progress from day to day. For “the Lord knoweth them that are His;” and “as many as are led by the Spirit of God, they are sons of God,” but by grace, not by nature. For there is but one Son of God by nature, who in His compassion became Son of man for our sakes, that we, by nature sons of men, might by grace become through Him sons of God. For He, abiding unchangeable, took upon Him our nature, that thereby He might take us to Himself; and, holding fast His own divinity, He became partaker of our infirmity, that we, being changed into some better thing, might, by participating in His righteousness and immortality, lose our own properties of sin and mortality, and preserve whatever good quality He had implanted in our nature perfected now by sharing in the goodness of His nature. For as by the sin of one man we have fallen into a misery so deplorable, so by the righteousness of one Man, who also is God, shall we come to a blessedness inconceivably exalted. Nor ought any one to trust that he has passed from the one man to the other until he shall have reached that place where there is no temptation, and have entered into the peace which he seeks in the many and various conflicts of this war, in which “the flesh lusteth against the spirit, and the spirit against the flesh.”
Now, such a war as this would have had no existence if human nature had, in the exercise of free will, continued steadfast in the uprightness in which it was created. But now in its misery it makes war upon itself, because in its blessedness it would not continue at peace with God; and this, though it be a miserable calamity, is better than the earlier stages of this life, which do not recognize that a war is to be maintained. For better is it to contend with vices than without conflict to be subdued by them. Better, I say, is war with the hope of peace everlasting than captivity without any thought of deliverance. We long, indeed, for the cessation of this war, and, kindled by the flame of divine love, we burn for entrance on that well-ordered peace in which whatever is inferior is for ever subordinated to what is above it. But if (which God forbid) there had been no hope of so blessed a consummation, we should still have preferred to endure the hardness of this conflict, rather than, by our non-resistance, to yield ourselves to the dominion of vice.
Chapter 16.—The Laws of Grace, Which Extend to All the Epochs of the Life of the Regenerate.
But such is God’s mercy towards the vessels of mercy which He has prepared for glory, that even the first age of man, that is, infancy, which submits without any resistance to the flesh, and the second age, which is called boyhood, and which has not yet understanding enough to undertake this warfare, and therefore yields to almost every vicious pleasure (because though this age has the power of speech, and may therefore seem to have passed infancy, the mind is still too weak to comprehend the commandment), yet if either of these ages has received the sacraments of the Mediator, then, although the present life be immediately brought to an end, the child, having been translated from the power of darkness to the kingdom of Christ, shall not only be saved from eternal punishments, but shall not even suffer purgatorial torments after death. For spiritual regeneration of itself suffices to prevent any evil consequences resulting after death from the connection with death which carnal generation forms. But when we reach that age which can now comprehend the commandment, and submit to the dominion of law, we must declare war upon vices, and wage this war keenly, lest we be landed in damnable sins. And if vices have not gathered strength, by habitual victory they are more easily overcome and subdued; but if they have been used to conquer and rule, it is only with difficulty and labor they are mastered. And indeed this victory cannot be sincerely and truly gained but by delighting in true righteousness, and it is faith in Christ that gives this. For if the law be present with its command, and the Spirit be absent with His help, the presence of the prohibition serves only to increase the desire to sin, and adds the guilt of transgression. Sometimes, indeed, patent vices are overcome by other and hidden vices, which are reckoned virtues, though pride and a kind of ruinous self-sufficiency are their informing principles. Accordingly vices are then only to be considered overcome when they are conquered by the love of God, which God Himself alone gives, and which He gives only through the Mediator between God and men, the man Christ Jesus, who became a partaker of our mortality that He might make us partakers of His divinity. But few indeed are they who are so happy as to have passed their youth without committing any damnable sins, either by dissolute or violent conduct, or by following some godless and unlawful opinions, but have subdued by their greatness of soul everything in them which could make them the slaves of carnal pleasures. The greater number having first become transgressors of the law that they have received, and having allowed vice to have the ascendency in them, then flee to grace for help, and so, by a penitence more bitter, and a struggle more violent than it would otherwise have been, they subdue the soul to God, and thus give it its lawful authority over the flesh, and become victors. Whoever, therefore, desires to escape eternal punishment, let him not only be baptized, but also justified in Christ, and so let him in truth pass from the devil to Christ. And let him not fancy that there are any purgatorial pains except before that final and dreadful judgment. We must not, however, deny that even the eternal fire will be proportioned to the deserts of the wicked, so that to some it will be more, and to others less painful, whether this result be accomplished by a variation in the temperature of the fire itself, graduated according to every one’s merit, or whether it be that the heat remains the same, but that all do not feel it with equal intensity of torment.
