Ghosts and the dead
Can the dead come back?
All who die in God's grace and friendship, but still imperfectly purified, are indeed assured of their eternal salvation; but after death they undergo purification, so as to achieve the holiness necessary to enter the joy of heaven.
The Church gives the name Purgatory to this final purification of the elect, which is entirely different from the punishment of the damned. Cf. Council of Florence (1439): DS — Denzinger–Schönmetzer (Enchiridion Symbolorum); Council of Trent (1563): DS — Denzinger–Schönmetzer (Enchiridion Symbolorum); (1547): 1580; see also Benedict XII, Benedictus Deus (1336): DS — Denzinger–Schönmetzer (Enchiridion Symbolorum). The Church formulated her doctrine of faith on Purgatory especially at the Councils of Florence and Trent. the tradition of the Church, by reference to certain texts of Scripture, speaks of a cleansing fire: Cf. 1 Cor 3:15; 1 Pet 1:7.
As for certain lesser faults, we must believe that, before the Final Judgment, there is a purifying fire. He who is truth says that whoever utters blasphemy against the Holy Spirit will be pardoned neither in this age nor in the age to come. From this sentence we understand that certain offenses can be forgiven in this age, but certain others in the age to come. St. Gregory the Great, Dial. 4, 39: PL — Patrologia Latina (Migne); cf. Mt 12:31.
This teaching is also based on the practice of prayer for the dead, already mentioned in Sacred Scripture: "Therefore Judas Maccabeus] made atonement for the dead, that they might be delivered from their sin." 2 Macc 12:46. From the beginning the Church has honored the memory of the dead and offered prayers in suffrage for them, above all the Eucharistic sacrifice, so that, thus purified, they may attain the beatific vision of God. Cf. Council of Lyons II (1274): DS — Denzinger–Schönmetzer (Enchiridion Symbolorum). The Church also commends almsgiving, indulgences, and works of penance undertaken on behalf of the dead:
Let us help and commemorate them. If Job's sons were purified by their father's sacrifice, why would we doubt that our offerings for the dead bring them some consolation? Let us not hesitate to help those who have died and to offer our prayers for them. St. John Chrysostom, Hom. in 1 Cor. 41, 5: PG — Patrologia Graeca (Migne); cf. Job 1:5.
Each man receives his eternal retribution in his immortal soul at the very moment of his death, in a particular judgment that refers his life to Christ: either entrance into the blessedness of heaven-through a purification Cf. Council of Lyons II (1274): DS — Denzinger–Schönmetzer (Enchiridion Symbolorum); Council of Florence (1439): DS — Denzinger–Schönmetzer (Enchiridion Symbolorum); Council of Trent (1563): DS — Denzinger–Schönmetzer (Enchiridion Symbolorum). or immediately, Cf. Benedict XII, Benedictus Deus (1336): DS — Denzinger–Schönmetzer (Enchiridion Symbolorum); John XXII, Ne super his (1334): DS — Denzinger–Schönmetzer (Enchiridion Symbolorum).-or immediate and everlasting damnation. Cf. Benedict XII, Benedictus Deus (1336): DS — Denzinger–Schönmetzer (Enchiridion Symbolorum).
At the evening of life, we shall be judged on our love. St. John of the Cross, Dichos 64.
All forms of divination are to be rejected: recourse to Satan or demons, conjuring up the dead or other practices falsely supposed to "unveil" the future. Cf. Deut 18:10; Jer 29:8. Consulting horoscopes, astrology, palm reading, interpretation of omens and lots, the phenomena of clairvoyance, and recourse to mediums all conceal a desire for power over time, history, and, in the last analysis, other human beings, as well as a wish to conciliate hidden powers. They contradict the honor, respect, and loving fear that we owe to God alone.
