7 But I have no fear of death, says one, nor of the act of dying, but of a miserable death, of being beheaded. Did John then, I ask, die miserably? For he was beheaded. Or did Stephen die miserably? For he was stoned; and all the martyrs have thus died wretchedly, according to this objection: since some have ended their lives by fire; and others by the sword; and some cast into the ocean; others down a precipice; and others into the jaws of wild beasts, have so come by their death. To die basely, O man, is not to come to one's end by a violent death, but to die in sin! Hear, at least, the prophet moralising on this very matter, and saying, “The death of sinners is evil.” He does not say that a violent death is evil; but what then? “The death of sinners is evil.” And justly so; for after the departure from this life, there is an intolerable punishment; undying vengeance, the envenomed worm; the fire unquenchable, the outer darkness, the chains indissoluble; the gnashing of teeth, the tribulation, and the anguish, and the eternal justice.
