The First Apology Of Justin by Justin Martyr
Chapter XVIII.--Proof of immortality and the resurrection.
For reflect upon the end of each of the preceding kings, how they died the death common to all, which, if it issued in insensibility, would be a godsend to all the wicked. But since sensation remains to all who have ever lived, and eternal punishment is laid up (i.e., for the wicked), see that ye neglect not to be convinced, and to hold as your belief, that these things are true. For let even necromancy, and the divinations you practise by immaculate children, and the evoking of departed human souls, and those who are called among the magi, Dream-senders and Assistant-spirits (Familiars), and all that is done by those who are skilled in such matters -- let these persuade you that even after death souls are in a state of sensation; and those who are seized and cast about by the spirits of the dead, whom all call dæmoniacs or madmen; and what you repute as oracles, both of Amphilochus, Dodana, Pytho, and as many other such as exist; and the opinions of your authors, Empedocles and Pythagoras, Plato and Socrates, and the pit of Homer, and the descent of Ulysses to inspect these things, and all that has been uttered of a like kind. Such favour as you grant to these, grant also to us, who not less but more firmly than they believe in God; since we expect to receive again our own bodies, though they be dead and cast into the earth, for we maintain that with God nothing is impossible.
