Proverbs 14:8 The wisdom of the prudent is to understand his way, but the folly of fools is deceit.<quoted text>I pray for the dead. I also ask the dead to pray for me. We know the Saints and Mary are alive in Heaven.
2 Maccabees 12:43-46
43 He then took up a collection among all his soldiers, amounting to two thousand silver drachmas, which he sent to Jerusalem to provide for an expiatory sacrifice. In doing this he acted in a very excellent and noble way, inasmuch as he had the resurrection of the dead in view;
44 for if he were not expecting the fallen to rise again, it would have been useless and foolish to pray for them in death.
45 But if he did this with a view to the splendid reward that awaits those who had gone to rest in godliness, it was a holy and pious thought.
46 Thus he made atonement for the dead that they might be freed from this sin.
