Final Judgement, Heaven and Hell (by Danny Manthei)

*Theological interpretations and understandings aside, the teaching on Hell and the Last Judgment can be summarized in this way:

IV. HELL

1033 We cannot be united with God unless we freely choose to love him. But we cannot love God if we sin gravely against him, against our neighbor or against ourselves: "He who does not love remains in death. Anyone who hates his brother is a murderer, and you know that no murderer has eternal life abiding in him."⁶¹² Our Lord warns us that we shall be separated from him if we fail to meet the serious needs of the poor and the little ones who are his brethren.⁶¹³ To die in mortal sin without repenting and accepting God's merciful love means remaining separated from him for ever by our own free choice. This state of definitive self-exclusion from communion with God and the blessed is called "hell."

1034 Jesus often speaks of "Gehenna" of "the unquenchable fire" reserved for those who to the end of their lives refuse to believe and be converted, where both soul and body can be lost.⁶¹⁴ Jesus solemnly proclaims that he "will send his angels, and they will gather . . . all evil doers, and throw them into the furnace of fire,"⁶¹⁵ and that he will pronounce the condemnation: "Depart from me, you cursed, into the eternal fire!"⁶¹⁶

1035 The teaching of the Church affirms the existence of hell and its eternity. Immediately after death the souls of those who die in a state of mortal sin descend into hell, where they suffer the punishments of hell, "eternal fire."⁶¹⁷ The chief punishment of hell is eternal separation from God, in whom alone man can possess the life and happiness for which he was created and for which he longs.

1036 The affirmations of Sacred Scripture and the teachings of the Church on the subject of hell are a call to the responsibility incumbent upon man to make use of his freedom in view of his eternal destiny. They are at the same time an urgent call to conversion: "Enter by the narrow gate; for the gate is wide and the way is easy, that leads to destruction, and those who enter by it are many. For the gate is narrow and the way is hard, that leads to life, and those who find it are few."⁶¹⁸

Since we know neither the day nor the hour, we should follow the advice of the Lord and watch constantly so that, when the single course of our earthly life is completed, we may merit to enter with him into the marriage feast and be numbered among the blessed, and not, like the wicked and slothful servants, be ordered to depart into the eternal fire, into the outer darkness where "men will weep and gnash their teeth."⁶¹⁹

1037 God predestines no one to go to hell;⁶²⁰ for this, a willful turning away from God (a mortal sin) is necessary, and persistence in it until the end. In the Eucharistic liturgy and in the daily prayers of her faithful, the Church implores the mercy of God, who does not want "any to perish, but all to come to repentance":⁶²¹

Father, accept this offering from your whole family. Grant us your peace in this life, save us from final damnation, and count us among those you have chosen.⁶²²

V. THE LAST JUDGMENT

1038 The resurrection of all the dead, "of both the just and the unjust,"⁶²³ will precede the Last Judgment. This will be "the hour when all who are in the tombs will hear [the Son of man's] voice and come forth, those who have done good, to the resurrection of life, and those who have done evil, to the resurrection of judgment."⁶²⁴ Then Christ will come "in his glory, and all the angels with him. . . . Before him will be gathered all the nations, and he will separate them one from another as a shepherd separates the sheep from the goats, and he will place the sheep at his right hand, but the goats at the left. . . . And they will go away into eternal punishment, but the righteous into eternal life."⁶²⁵

1039 In the presence of Christ, who is Truth itself, the truth of each man's relationship with God will be laid bare.⁶²⁶ The Last Judgment will reveal even to its furthest consequences the good each person has done or failed to do during his earthly life:

All that the wicked do is recorded, and they do not know. When "our God comes, he does not keep silence.". . . he will turn towards those at his left hand: . . . "I placed my poor little ones on earth for you. I as their head was seated in heaven at the right hand of my Father - but on earth my members were suffering, my members on earth were in need. If you gave anything to my members, what you gave would reach their Head. Would that you had known that my little ones were in need when I placed them on earth for you and appointed them your stewards to bring your good works into my treasury. But you have placed nothing in their hands; therefore you have found nothing in my presence."⁶²⁷

1040 The Last Judgment will come when Christ returns in glory. Only the Father knows the day and the hour; only he determines the moment of its coming. Then through his Son Jesus Christ he will pronounce the final word on all history. We shall know the ultimate meaning of the whole work of creation and of the entire economy of salvation and understand the marvelous ways by which his Providence led everything towards its final end. The Last Judgment will reveal that God's justice triumphs over all the injustices committed by his creatures and that God's love is stronger than death.⁶²⁸

1041 The message of the Last Judgment calls men to conversion while God is still giving them "the acceptable time, . . . the day of salvation."⁶²⁹ It inspires a holy fear of God and commits them to the justice of the Kingdom of God. It proclaims the "blessed hope" of the Lord's return, when he will come "to be glorified in his saints, and to be marveled at in all who have believed."⁶³⁰
